    Flood protection
    FIELD OF THE INVENTION
    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a storm surge protection for protecting an underlying area from a rising water level from a foreground area, wherein the storm surge protection operates between a bottom and a water surface, wherein the storm flood protection comprises at least a longitudinal and elevation barrier element where the longitudinal direction extends in an operating situation. substantially across a region, for example, a river, a fjord, a river or a river delta, where the altitude in an operational situation extends from the bottom of a region, for example a river, a fjord, a river or a river delta, and up, where the at least one locking element, during operation, interacts with a foundation where the foundation is arranged at the bottom of the current area.
    The invention further encompasses a method of operating such a storm surge protection to protect an underlying area against a rising water level from an adjacent area.
    BACKGROUND OF THE INVENTION
    It is generally known to use different systems to curb rising water levels, whether due to tides, winds or rain. In the following, these systems are collectively referred to as storm surge protection - even if these are situations that cannot be attributed to a definite storm surge.
    For example, a number of different locks are known, for example at several Danish rivers in the North Sea. These locks work with side-hung gates or with hoist gates, where the gates can be opened and closed as needed, thereby protecting low-lying areas further inland from flooding with seawater when it blows heavily from the west. Typically, free locks or chamber locks are used for such tasks. Locking systems work well and efficiently to block off relatively narrow passages, but at the same time require a not insignificant system structure. For wider passages such as the mouth of a fjord or off a bay, the known gate solutions are not suitable. Partly because of the extent to be curbed, but also because of both the construction costs and the often unattractive architectural influence of the area.
    DK 2017 70235 A1
    Furthermore, there are also known flap gates arranged on the seabed and from there can be tilted about a horizontal axis at the seabed when there is a need to curb. As mentioned, this entire structure is arranged on the seabed, which of course also requires extensive construction and foundation work. In addition, there are a number of challenges in maintaining the plant, as sanding and deposition of sediment will typically occur over time, and of course there is a common challenge with supervision and maintenance of a plant mounted underwater. At the same time, the structure is complicated and extremely costly to establish on the bottom of a fjord or similar.
    Another variant of a storm surge protection is the so-called Moses gates, which are known from Venice. These gates are also arranged on the seabed in a foundation, but are raised only by allowing compressed air to displace water from the interior of the gate elements. This increases the buoyancy of the mentioned port elements and therefore rises from the seabed and acts as a high waterproofing. This solution avoids complex and vulnerable chain hoists or other hoisting devices to raise the port elements from the seabed. In terms of maintenance and inspection, there is no immediate difference between the gates of Moses and the gates mentioned above.
    The disadvantage of the mentioned types of storm surge fuses is that they require considerable foundations and / or structures that are typically large and unsightly and not least costly to establish and replace when the time comes. The reason for the size of the foundations / structures is that they must be able to withstand the horizontal forces that occur when retaining water from entering a given area. The forces on the two respective sides of a storm surge fuse, of course, remain in balance as long as the water level is the same on both sides, but when the water level rises on one side, horizontal forces arise which must be absorbed into the foundation of the particular structure.
    The object of the invention
    SUMMARY OF THE INVENTION It is the object of this invention to provide a solution to a storm surge protection which provides a good, effective and simple solution by which a rising water level can be retained on the outside of a storm surge protection, thereby avoiding or within it.
    DK 2017 70235 A1 minimize any possible flood of a low lying area on the inside of said storm surge protection.
    The object is also to provide a storm surge protection where the foundation is not burdened with neither vertical nor horizontal forces to the same extent as is known from the known solutions, for example solutions mentioned above.
    It is a further object of the invention to provide a method of activating, deactivating and storing such storm surge protection.
    Description of the Invention
    The invention, as mentioned above and in the preamble of claim 1, relates to a storm surge protection for protecting an underlying area against a rising water level from a foreground area, where the storm surge protection operates between a bottom and a water surface, wherein the storm flood protection comprises at least one longitudinal barrier element and an altitude direction in which the longitudinal direction in an operating situation extends substantially across an area, for example a river, a fjord, a river or a river delta, where the altitude direction in an operational situation extends from the bottom of an area, for example a river, fjord, a river or a river delta, and up, where at least one barrier element during operation cooperates with a foundation, the foundation being arranged on the bottom of the current area.
    The new feature of a storm surge protection in accordance with the invention is that said storm surge protection comprises at least one movable and buoyancy-balanced locking member, said locking member comprising an adjustable ballast system for controlling said buoyancy balance, wherein said storm surge protection foundation comprises a bottom rail system. at least one locking member comprises contact means, said contact means being arranged for contact with said bottom rail system.
    The bottom rail system and the mentioned contact means are NOT firmly connected, but cooperate only in that the locking element rests with a harmonized force - according to how the ballast is regulated in the respective locking elements. There is thus a "loose connection" between the bottom rail system and the locking element (s). In the bottom rail system is
    DK 2017 70235 A1 which arranged a contact surface which - when the locking element is in place - forms a system for the contacting means of the locking element. On one or both of these, seals may be arranged which, by contact between the locking element and the bottom rail, prevent water from flowing freely from one side of the storm surge protection to the other side. In a simple embodiment, there may be an elastic coating or lip on the contact means of the locking element, for example a rubber seal.
    The bottom rail system may, for example, be U- or I-shaped and cooperate with a corresponding shape on the respective locking elements. In a preferred variant of a bottom rail system, this can advantageously be fixed with rammed posts or the bottom rail system can be fixed with the known "suction bucket principle". Thus, there is no significant impact on the bottom as neither major excavations nor extensive construction work is required. The bottom rail system can be laid out in sections placed and anchored with suitable processes on the bottom, after which the system is ready to receive the respective locking elements. Due to the simple principle, construction costs are relatively low.
    A storm surge protection according to the invention may be designed such that the at least one buoyancy-balanced barrier element comprises a fixed ballast and an adjustable ballast, the adjustable ballast being water. The fixed ballast is intended to ensure an almost equilibrium of the locking elements, which can be seen with concrete, iron, stone or other suitable ballast. The adjustable ballast is most advantageously constituted by water, since ample quantities are available using the storm surge protection. When the individual locking elements are located, a ballast control can be made so as to obtain a sufficient, but still modest downward force effect on the bottom rail system. It is only to seal a flow from one side to another that this force is established. In use, further correction can also be made in the event that situations arise where it is considered relevant.
    A storm surge protection according to the inventions is special in that the at least one locking element is arranged with its buoyancy center higher than its center of gravity and thus is stable.
    DK 2017 70235 A1
    When the locking element is stable it will be self-creating for an angle of heel less than the so-called Angle of Vanishing Stabillity, which is also known from, for example, ships. This means that the locking element, which is held in place at the bottom in or on the said bottom rail system, will be able to roll to the side when there is a difference in the water level on one of the two sides of the locking element, but that a locking is still maintained.
    Under normal use, storm surge protection will typically be established to protect, for example, a port or residential area from flooding in connection with a storm surge or other situation that may cause an undesirable rise in water. Therefore, it will typically be seawater that is blocked, so that the blocking elements can be arranged to primarily incline to one side, namely inland, as the water presses from the outside. By having the center of gravity positioned as low as possible, and thus below the buoyancy center, good stability is achieved and at the same time a limited heel of the individual locking elements.
    In a embodiment, a storm surge protection according to the invention may comprise that the contact means of at least one barrier element and the bottom rail system are arranged so that the barrier element under the influence of a greater water pressure on one side than on the other side is allowed to tilt at a given angle with respect to the bottom rail system. , whereby the buoyancy center of the locking element is displaced relative to its center of gravity.
    By tilting and thus by displacing buoyancy center with respect to the center of gravity, a tipping torque is obtained which will affect the bottom rail system and contact means with a horizontal force proportional to the magnitude of the tipping torque which occurs when the buoyancy center and center of gravity are relatively displaced. In addition, a resultant force arises in the opposite direction, which will push against the larger water pressure in the front, ie on the outside of the storm surge protection. This creates a balance in the system and the forces from the higher water level on one side of the storm surge protection are absorbed as horizontal forces in the system. Any vertical forces, that is, forces pressing the bottom rail system, are adjusted by controlling the buoyancy of the respective locking element (s). This adjustment occurs, if necessary, by adjusting the amount of ballast in the individual locking elements.
    DK 2017 70235 A1
    The storm surge protection according to the invention may in one embodiment comprise that at least one of the at least one locking element contact means and the bottom rail system comprise passive valve means, wherein said valve means are activated when the water pressure is greater behind the storm surge protection than on the front.
    With such passive valve means, the advantage is obtained that when the water level is lowered again and the storm surge protection can be deactivated again, water on the underlying side of the stormfold protection is allowed to pass the storm flood protection, thereby again establishing balance in the respective blocking elements, ie buoyancy center and center of gravity. are again aligned to each other. This is done by the underlying water exerting a greater force on the locking elements than the present water. Thereby, a horizontal force is obtained which moves the locking elements relative to the bottom rail system. Either the bottom rail system or the lower part of the locking members or alternatively both have a type of spacer that allows water to pass one way. This is only possible when there is greater pressure from the back than from the front of the locking elements. The illustrative drawings show an example of such a variant of the invention.
    In a variant of a storm surge protection in accordance with the invention, the at least one locking member may be formed with a substantially tapered cross-section, with the pointed end facing the bottom rail system and the wide end thus facing upwards.
    By having a more or less symmetrical cross-section of the locking element and by having an increased volume above and a fixed ballast in the pointed bottom part, it is ensured that the buoyancy center is placed above the center of gravity and thus a natural stability is achieved. As mentioned, the fixed ballast is located at the pointed end and contact means can also be arranged for abutments against the bottom rail system. The fixed ballast is aligned so that the locking element can flow, thus being towed in place in the rail system in an operating position or in a storage magazine. A suitable shape has been found to substantially correspond to a cylinder section with an angle of approx. 60 degrees. However, it is clear that other sizes or shapes may be suitable as well. The most attractive design can advantageously be determined according to the normal water level and the typical water level in, for example, a flood. The important thing at all times must be that a storm surge protection according to the 2017 70235 A1 invention is optimally designed for exactly the location where it is to be used.
    In a particular variant of a storm surge protection according to the invention, the at least one barrier element may comprise an adjustable barrier, the adjustable barrier being arranged tiltably or otherwise movable at the upper edge of the barrier element.
    Said barrier can thus be tilted up or moved to an effective position in the event that the water level in the foreground area is expected to rise to a height higher than the body of the locking element itself. Should the water level rise further and above both the barrier element's body and barrier, the barrier elements will remain active and stable and allow only an overflow, but they will not collapse or overlap and become unstable.
    Such a barrier can advantageously be designed as a kind of flap which is pivoted in place about an axis in the longitudinal direction of the locking element and then locked in this position, either by an actual fixation or alternatively by performing the hinge construction as self-locking. Such a flap, for example, can be one meter high or even more. The important thing about the height of the flap is that it is dimensioned in relation to the overall buoyancy and shape of the locking element itself, and not least in relation to how much the locking element slopes under the influence of the larger water pressure on one side.
    In yet another variant of a storm surge protection according to the invention, the at least one locking member may be arranged pivotally about a substantially vertical axis, whereby the at least one locking member, after rotation about said axis, is lowered in place in a bottom rail system, and thereby blocking off between a front area and a rear area.
    Said variant of a storm surge protection is particularly suitable for use with, for example, creeks and rivers with a limited extension in the width direction corresponding to the longitudinal direction of the storm surge protection. In such cases, the storm surge protection can be established from either one or both sides of the current stream, and this can be done with a relatively simple construction whose primary purpose is to swing a locking element in place in an active or in a passive position. Therefore, the swing mechanism itself should not
    DK 2017 70235 A1 could transmit more forces than is necessary to carry out the actual positioning of the locking elements. All forces from the operation itself, that is, when a higher water level occurs on one side of the locking elements, is primarily absorbed by the locking elements themselves and partly by the bottom rail system, while the swing mechanism is only marginally loaded during operation.
    The storm surge protection according to the invention may in one embodiment comprise at least two or more locking elements, wherein at least one end surface of a locking element comprises sealing means for abutting an end surface of an adjacent locking element.
    Said variant of a storm surge protection may, for example, be provided with sealing means in the form of a kind of fender (an elastic plastic or rubber element) arranged on the end of the locking elements. In one embodiment, the respective ends of two adjacent locking elements can both be provided with sealing means which are either in contact with each other or complement each other, for example by being arranged in a mirror-facing relationship. By having sealants on the ends of the locking elements, the advantage is obtained that they can be moved relative to each other and, of course, also that no more water penetrates than is most necessary through the storm surge protection. Obviously, it is not a goal as such to create a very close joint between two adjacent ends, but that the joint should also not allow any significant flow.
    A storm surge protection may be provided with a walkway on top of the blocking elements so that they can be serviced and / or inspected under bmg or alternatively, such a walkway can be used for recreational purposes. For example, the previously mentioned barrier in the form of a flap at the upper edge of the locking elements may constitute a railing for such a walkway. In that case, such a barrier can advantageously be established at both sides of the upper edge of the locking elements. Of course, a simpler form of railing can also be established.
    A particular variant of a storm surge protection may be provided with a float body mounted via a translational bearing on the low side of a gate element and which together
    DK 2017 70235 A1 constitutes a locking element. This variant is particularly suitable for reducing the force impact of a sill or bottom rail system in an existing lock or storm surge protection. This may be relevant in the case where the construction begins to show signs of weakness due to age or other degradation. By mounting a ballast-balanced floating body on the low side of a door element, a support effect is obtained partly because of the overturning torque which counteracts the pressure of the water on the frame / bottom rail system and thereby relieves it in relation to the previous construction. At the same time, the advantage is obtained that the locking element itself can be designed as a gate - it may even be a previous gate in a lock or the like, which is rebuilt and added to a floating body. The translational bearing only has to ensure that the floating body is held in place against the wall of the gate element at the desired level relative to the water level.
    Regardless of the fact that some type of locking element is blocked, there will typically be a rise in water on both the outside side - ie in front of the locking elements and on the inside side - ie behind the locking elements. This is because, typically - there will always be a supply of water from the hinterland, regardless of the fact that there is a flood that pushes water from the outside into, for example, a fjord or river.
    The invention further relates to a method for establishing a storm surge protection for protecting an underlying area against a rising water level from a foreground area, where the storm flood protection acts between a bottom and a water surface, wherein the storm flood protection comprises at least a longitudinal and elevation barrier element. wherein the longitudinal direction in an operating situation extends substantially across an area, for example, a river, a fjord, a river or a river delta, where the elevation direction in an operational situation extends from the bottom of an area, for example a river, a fjord, a river. river or a river delta, and up where the at least one barrier element, in operation, interacts with a foundation where the foundation is arranged at the bottom of the current area.
    The new feature of a method according to the invention is that the establishment of said storm surge protection comprises at least the following process steps:
    positioning one or more buoyancy-balanced locking elements over a bottom rail system,
    DK 2017 70235 A1
    - adjusting the amount of ballast in the respective locking elements so that the locking elements are fixed against horizontal movement in said bottom rail system.
    This provides a solution in which the respective locking elements are placed in an area when a need is anticipated. Typically, a storm surge or other situation that causes an elevated water level can be predicted with up to two days notice. Thereafter, there is plenty of time to bring the necessary locking elements into place in the provided bottom rail system. As the individual locking elements are fluid, they can be towed in place and the ballast can be increased to lower or lower the bottom rail system.
    In a preferred embodiment, barrier elements for a storm surge protection, as indicated above, can advantageously be connected to chains and thus towed in place - as beads on a leash - in the rail system and lowered, either simultaneously or one by one, into the underlying bottom rail system.
    Prior to placing the necessary locking elements, the bottom rail system can advantageously be cleaned with a cleaning tool drawn through the bottom rail, thereby removing sand and other sediment and thus ensuring a desired density between the respective locking elements and the bottom rail system. Such a cleaning tool can, in principle, be constituted by a '' spit plow 'which lifts the unwanted sand and sediment up and out of the bottom rail system. You can also imagine that the cleaning is done with a tool where water is flushed down the bottom rail and thereby removes sand and sediment. This purification can be done in many conceivable ways and it is clear that the said methods for one of ordinary skill in the art are only two of many possible.
    When the storm surge protection is not in use, it can advantageously be stored in a dedicated magazine where the individual locking elements can possibly be stored side by side. In a preferred embodiment of such a magazine, the individual locking elements may optionally be stored submerged by filling them with ballast water so that they are not visible. In certain scenic areas or other selected areas, this can be an advantageous solution for aesthetic reasons.
    DK 2017 70235 A1
    If the barrier elements for storm surge protection are stored in a dedicated reservoir, then this reservoir can advantageously be supplied to fresh water from streams and drainage pipes, thereby providing the opportunity to switch between fresh water and saline in this reservoir. Precisely the fact that switching between fresh water and saline will help reduce the fouling of bacteria, plants or animals on the barrier elements, as these fouling typically cannot thrive in both saline and fresh water. Thus, by regularly switching between fresh water and saline water and possibly brackish water in such a reservoir, for example by switching between flow or overflow, limitations can be limited to a minimum.

    Detailed description
    In FIG. 1, a storm surge protection 1 is shown, which comprises a locking element 2 in a bottom rail 3 with equal water level on both the low water side 4 and on the high water side 5.1 The locking element 2 is indicated the center of gravity 6 and the buoyancy center 7. These are placed above each other, indicating a stable construction. At the bottom of the locking element 2 is seen its contact means 8, which also constitute a ballast compartment 9. At the bottom of the locking element 2, in the ballast compartment 9, a fixed ballast of iron, concrete or the like is arranged. In addition, an adjustable ballast consisting of, for example, water can be established. This adjustable ballast can advantageously be pumped in from the surroundings with equipment adapted thereto, which however is not shown in the figure.
    The contact means 8 rest in the bottom rail 3, thereby preventing flow
    DK 2017 70235 A1 any significant amount of water from one to the other side of the storm surge protection 1.1 shown, the contact means 8 are shaped so that the blocking element 2 can be tilted towards both the low water side 4 and the high water side 5, while creating a larger contact surface between the locking means 8 of the locking element and the bottom rail 3.
    FIG. 2 shows a locking element 2 in a bottom rail 3 and in an operating position, where the water level is practically as high as possible on the high water side and where the barrier 10 at the upper edge of the locking element is maximally utilized. As can be seen, the locking element here is pressed to one side as a function of the larger water level on the high water side 5. The increased pressure on one side of the locking element 2 is offset by the overturning moment caused by the buoyancy center 7 being displaced in relation to to the center of gravity 6. The storm surge fuse 1 is precisely designed to be balanced at equal water level on both sides and so as to be tilted by an increased water level on one side, but this is precisely offset by the torque arising as a function of , that the buoyancy center is shifted relative to the center of gravity. At the same time, a storm surge protection as shown here is balanced so that only minimal vertical forces are applied to the bottom rail system 3. However, it must be mentioned that in the intermediate positions from the resting position, ie where there is equal water level on both sides, and to full active dam, will be an upward force component. In the starting position, the angle on the high water side is 5, for example 24 degrees. The opposite side, ie on the lawand side 4, also has the locking element at an angle of approx. 24 degrees and the system is in stable rest.
    At full load, as seen here in FIG. 2, the locking member 2 is now rotated 24 degrees and the high water side 5 is now vertical and the opposite side, the lawand side is approx. 48 degrees from the vertical and the system is again at rest.
    On the way from unloaded to maximum loaded, however, with this design a vertical pressure component will appear. This means that the dam will float upwards until equilibrium occurs. At a low water level behind a dam of, for example, 9.4 meters and a high water level rising in front of the dam, at approx. The 12 degree slope means an extra buoyancy of just over a ton / meter, which means that a circular top locking element will lift approx. 0.34 meters up from the bottom rail 3. This is based on the equilibrium and no vertical forces acting at a uniform water level
    DK 2017 70235 A1 for example 9.4 meters on each side of a locking element. Incidentally, this example is based on a storm surge fuse 1, with a total height of 10.6 meters measured from the bottom rail 3 location on the bottom.
    Below is a numerical example of the above-mentioned situation, where the third column indicates the angle of the high water side relative to the vertical. In equilibrium - that is, at equal water levels on both sides the angle is 24 degrees and at full load it is 0 degrees.
    The sixth column indicates the additional buoyancy [tonnes / meter] that occurs when the barrier element 2 is loaded to a slope of 24 degrees corresponding to the high water side becoming vertical.
    The example of the figure shows that an additional buoyancy of 1.15 tonnes / meter occurs at a slope of 12 degrees, which is also seen in the graph below, showing the buoyancy as a function of the slope angle.

    This vertical movement demands that the bottom rail system 3 can accommodate the vertical movement and still hold the rising water or that the ballast is adjusted along the way, thereby maintaining a very small load on the bottom rail 3. Alternatively, the bottom rail system 3 can be arranged. to take up this minimum load at the start and end, so that no lifting of the floating element occurs during the journey from unloaded to fully loaded.
    Another alternative may be to design the top geometry of the locking element so that during rotation ffa one of the two resting positions towards the other resting position loses buoyancy and thereby provides a substantially correspondingly opposite force. This can be done, for example, by forming the top of the locking element 2 with a downward recess.
    FIG. 3 shows an example of a U-shaped bottom rail 3 in which the locking element 2 rests. The contour of the contact means and the lower part of the blocking element is here drawn with a thick line and at the bottom is a ballast compartment 9 for solid ballast, and above this is another ballast compartment in which can be supplied or from which ballast can be removed. Such an adjustment of ballast can advantageously be made due to the rotated position and load degree of the locking element 2. Whether there is a downward force or not from the total
    DK 2017 70235 A1 system of buoyancy and gravity, then a storm surge protection 1, as shown here in fig. 3, be close to the bottom, as the contact means 8 will contact one side of the bottom rail 3 due to the greater water pressure on one side of the locking member 2. In this figure, the barrier 10 is also seen as a foldable element. along the high water side 5 at its hinge line 11.
    In FIG. 4 is another example of a bottom rail 3, but here is the bottom rail 3 with Iform. In principle, there is no difference between the two solutions shown, and one solution is far from being better than the other. The two examples are given to show that several alternatives exist and it is to be understood that the important thing is that a contact surface is formed between the bottom rail system 3 and the contact means 8 of the locking element 8.
    FIG. 5 shows an example of storm surge protection 1, where a return valve 12 is arranged at the lower edge of the locking element 12. The return valve 12 serves the purpose of closing water out of the low water side 4 when the water level on the high water side 5 has again dropped to a level corresponding to or below the level of the low water side. 4. In the situation shown, the return valve 12 is closed, showing a situation with higher water level on the high water side 5 than on the low water side 4. As long as the horizontal pressure on the high water side 5 is greatest, the contact means 8 will press against the bottom rail 3 and ensure , that is sealed. As the horizontal pressure from the water changes direction, the entire locking element will be pressed against the other side of the bottom rail system 3, and as a number of projections are formed at the return valve 12, water will be allowed to flow downwards and past the contacting means 8 of the locking element. Hereby pressure is equalized and the locking elements 2 are relieved, as seen in Fig. 6.
    In FIG. 7, a storm surge protection 1 is seen in the open state, where the individual locking elements 2 are arranged side by side in a magazine 13.1 the magazine 13, the locking elements can be partially stored above the water, but they can also be stored submerged and thus not visible by filling ballast in the locking elements 2 and thereby lowering them. The magazine 13 may advantageously be arranged so that the height of the edges is below the normal water level, whereby also the magazine 13 is immediately hidden from the naked eye. When the storm surge protection 1 is to be used, the respective locking elements 2 are pulled / towed in place over the bottom rail 3 and between the shown side pieces 14. Hereafter or as they are
    GB 2017 70235 A1 single locking elements 2 come into place, so the ballast is adjusted as needed so that the necessary seal and any downward force is obtained. Thereafter, the storm surge protection 1 is ready for use.
    FIG. 8 shows in principle the same as FIG. 7, but here the storm surge protection 1 is established and the respective locking elements 2 are in place, while only the contour of the locking elements 2 is seen in the magazine 13.
    FIG. 9 shows a barrier element 2 with a walkway on the upper side, where a barrier 10 provides shielding to the sides and where additional railings 15 are established between the outer barriers 10. A walkway can have many shapes and it can be as wide as the surface of the barrier element or it can be positioned at one side or in the middle, and the railing can have numerous shapes.
    FIG. 10 shows a cleaning tool 16 in a U-shaped bottom rail - seen from the end. The cleaning tool 16 here has a profile / shape that fits quite precisely to the bottom rail 3 so that it can be pushed or pulled through the bottom rail 3 and thereby used to remove sand and other sediment from the bottom rail 3. Such an operation will typically be performed immediately prior to positioning of the respective blocking elements 2 in connection with a storm surge warning. Furthermore, it may be extremely relevant that regular cleaning tool 16 is used to maintain the bottom rail 3 and thereby ensure that no such massive sanding or similar occurs that a storm surge protection will not be established within a relatively short time. .
    FIG. 11 shows the same cleaning tool as seen in FIG. 10, but here seen from the side. As can be seen in the figure, this is a simple plow-like device which, as mentioned, can be pushed, but which will preferably be pulled through the bottom rail, thereby displacing accumulated material.
    In FIG. 12 shows how an anchorage 17 of a U-shaped bottom rail 3 can be made to the bottom of the area where the storm surge protection 1 is to be established. As can be seen here, the bottom rail 3 is mounted in a recess on the bottom of, for example, a fjord, but it could in principle be arranged on top of the bottom. To place the bottom rail 3 directly
    DK 2017 70235 A1 on top of the bottom can be advantageous in the case of, for example, rock bottom.
    The anchor 17 is quite simple and consists in all of its simplicity of a number of ground skewers which are hit at the bottom at a suitable distance. Since there is virtually a balance in the locking elements 2 during operation, only small loads must be accommodated in the bottom rail 3, which is why this simple anchoring is sufficient. At the same time, close to negligible impact on the bottom and the environment on the bottom of the fjord, river or similar is achieved.
    FIG. 13 shows a storm surge fuse 1 with translational bearings 19 between a floating body 18 and a gate element 20, which together constitute a blocking element 2, shown here in the unloaded state. In this variant of the invention, the same principles are stated as in the above mentioned variant. Here, however, there is the difference that it is not the locking element 2 that creates the stabilizing creating torque, but rather this is created by the floating body 18. However, the effect is the same, since the floating element is connected to the gate element 20 via said translational bearings 19. Said translational bearings 19 have the sole purpose of ensuring that the float body can follow the water level on the lowland side 4.
    In FIG. 14, a storm surge fuse 1 with translational bearings 19 is shown between the floating body 18 and the port element 20 in the loaded state, the water level on the high water side 5 being considerably increased compared to that seen in FIG. 13th
