    BACKGROUND OF THE INVENTION
    The invention relates to a flood defense that can serve temporarily, and can be converted between a rest position and a flood-proof position.
    Such flood defenses are known in many embodiments, see inter alia applicants earlier patent applications WO 01/071099, WO 2006/062393, WO 2011/159146 and WO 2012/169877. Also common are flood defense bodies that are slidable over fixed rails between a rest position, in which an opening is left clear, such as for movement of vehicles or people, and a flood defense position. In the rest position, the displaceable flood defense bodies lie within or next to a fixed flood defense. In such arrangements, the fixed flood defense will occupy approximately 50% of the total length of the flood defense, which limits the feasible size of the passages in the rest position of the flood defense, which can also be disadvantageous in situations where a wide field of vision is desired , such as along rivers.
    There is a need for a temporary flood defense that can be quickly and easily applied to a water-responsible subsurface such as on a quay, a suitable public road, a boulevard or paved strip suitable for that purpose in a passage in a surrounding fixed water level calculated at elevated water level structures such as dikes, quay walls and or structures including buildings and retaining walls.
    There is a need for a temporary flood defense that is easy to build under difficult, sometimes stormy weather conditions.
    There is a need for a temporary flood defense which, despite being temporarily deployed, nevertheless provides a meter-high, sufficiently safe, retaining wall according to hydraulic engineering criteria.
    There is a need for a flood defense that can cause minor nuisance when not in use.
    SUMMARY OF THE INVENTION
    From one aspect, the invention provides a water-retaining structure comprising at least one movable retaining wall that is movable between a rest position, in which a passage between the water side and the land side is left clear, and a water-retaining position closing the passage, wherein the retaining wall comprises a first retaining wall part and comprises a second retaining wall part, wherein the first retaining wall part is an elongated holder for the second retaining wall part in the horizontal plane and has long sides and short sides, in particular is hollow, one long side forming a water-retaining, wet side and the other long side the opposite, dry side, wherein the second retaining wall part is displaceable between a mountain or rest position and a water-retaining position extending upwards from the first retaining wall part, the first retaining wall part being rotatable about a vertical axis of rotation between a rest position in which the passage is substantially free and a water-retaining position in the passage.
    The retaining wall according to the invention can be present in the immediate vicinity of placement and brought into the active position with a simple turning movement, in which a first water-retaining action is already offered with the first retaining wall part. If required, the water retaining height can be increased with the second retaining wall section ready. In the rest position, the retaining wall can be kept rotated to a position in which it limits the passage as little as possible and the nuisance for traffic and / or visibility can remain small.
    The second retaining wall part can be located on the first retaining wall part as a cover. In one embodiment the second retaining wall part is received in the rest position in the first retaining wall part. This can be in the form of stackable baffles which are accommodated flat on top of each other or standing next to each other in the first retaining wall part. The second retaining wall part can also be designed as a wall, which can then be vertically displaceable between a rest position included in the first retaining wall part and a water-retaining position extending upwards from the first retaining wall part. If a line is taken as a reference, according to which the passage extends (in the day), which line runs substantially parallel to the water barrier to be realized, the first retaining wall part can extend in its rest position transversely of the passage line to the dry side. In that case the passage is minimized in the rest position.
    In one embodiment the vertical axis of rotation is located on a first short side of the first retaining wall part. A movable retaining wall, for example, can be attached to a fixed, permanently water-retaining wall at the location of a hinge with a vertical axis.
    In an embodiment in which the passage has a relatively large width (in the day), the flood defense may comprise a plurality of said rotatable retaining walls, first retaining wall parts, each of which can be rotated about its own vertical axis at places in the passage remote from the boundaries of the passage attached to the surface. Intermediate positions are thus provided. In this case, retaining walls can be arranged in pairs, with the pivot axes of the first retaining wall parts together or coinciding. Within a pair the two retaining wall parts are then rotated in mutually opposite directions from the rest position to the reversed position.
    In an embodiment in which the passage may be limited or not occupied by the retaining walls, in particular at the location of the connection to fixed walls at the boundaries of the passage, the hinge is situated on a first short side, at a distance from the dry side , viewed along a horizontal line across the dry side. In an embodiment thereof, the hinge is located at a location between the two ends of the first short side. In another embodiment, the hinge is located at the angle between the wet side and the first short side
    In one embodiment, the passage is bounded by two fixed walls to each of which a said movable retaining wall is rotatably mounted and wherein one or more of said movable retaining walls are arranged in the passage, wherein in the case of several pairs they move in the direction of the passage line be spaced apart, in particular at a regular distance.
    In one embodiment, the retaining wall is provided with struts for supporting the second retaining wall part in the water-retaining position, which struts are displaceable between an inactive position and an active position. In this case a brace can be connected to each short side of the first retaining wall part in a manner rotatable about a horizontal axis of rotation, the braces extending in their inactive position over the top of the first retaining wall part, in particular forming a cover, wherein, preferably, the axis of rotation is transverse to the wet side. In the inactive position, the second retaining wall part accommodated in the first retaining wall part can cover, wherein, preferably, the struts have a length corresponding to half a length of the first retaining wall part.
    In one embodiment the retaining wall is provided with second conductors for guiding the second retaining wall part in the displacement thereof between the rest position and the water retaining position, wherein a second conductor is connected to each short side of the first retaining wall part in a manner rotatable about a horizontal axis of rotation. wherein the second conductors are movable between an inactive position and an active position, wherein, preferably, the second conductors have a length corresponding to half a length of the first retaining wall part. The second conductors can also be adapted to support the second retaining wall part in the water-retaining position. The second conductors may further be provided with a third conductor for a hoisting cable or the like for pulling up the second retaining wall part. In the storage position, the second conductors can seal or cover the receiving space for the second retaining wall part.
    The first retaining wall part can be provided with first conductors for the second retaining wall part in the movement thereof between the rest position and the water-retaining position, the second conductors in their active position being in line with the first conductors.
    In a simple embodiment, the second conductors can be attached to the struts and thus form a unit that can be moved, can be moved as a whole. Making braces and second conductors active then coincides.
    The second guides can be attached to the struts on the strut edge on the water side.
    In one embodiment, the second conductors and / or the struts are provided with means for coupling adjacent struts of adjacent movable retaining walls.
    The first retaining wall parts can also be provided with means for mutual coupling.
    In one embodiment, the water-retaining structure is provided with an anchor accommodated in the subsurface for fixing the first retaining wall part at a distance from the vertical axis of rotation of the first retaining wall part in its water-retaining position. In the embodiment in which the axis of rotation is located on the first short side, the anchor can be active near the second short side. In that case the anchor can act on two adjacent first retaining wall parts.
    The anchor can be displaceable between a rest position in which it does not protrude from the substrate and an active position in which this is in engagement with the first retaining wall part, the anchor being spring-tensioned to the active position.
    The retaining wall according to the invention can offer a considerable moment arm, in the direction perpendicular to the passage, whereby the force absorption can be promoted. The first retaining wall part can for instance have a water-retaining height of H, wherein the width B, viewed in a horizontal direction transverse to the water-retaining side, is at least 1/3 H.
    The water-retaining height of the second retaining wall portion can approximate that of the first retaining wall portion.
    In one embodiment the water barrier according to the invention comprises a series of retaining walls, wherein in the water retaining position the adjoining first retaining wall parts connect to each other at an angle that deviates from 180 degrees, the successive angles being of opposite sign. In this case, the retaining walls in the water-retaining position can form series of pairs, the lengths of the two first retaining wall sections being different within the pairs, with a relatively longer first retaining wall section and a shorter first retaining wall section of the one pair connecting in the water retaining position on a longer first retaining wall section of the next pair.
    From a further aspect, the invention provides a water barrier comprising at least one retaining wall, wherein the retaining wall comprises a first retaining wall part and at least one second retaining wall part, wherein the first retaining wall part is a holder of the second retaining wall part elongated in the horizontal plane, wherein the second retaining wall part is movable is between a mountain or rest position included in the first retaining wall part and a water-retaining position extending upwards from the first retaining wall part, wherein the retaining wall is provided with struts for supporting the second retaining wall part in the water-retaining position, which struts are movable between an inactive position and an active position, the struts forming a movable, rotatable unit as a whole with receivers mounted thereon for receiving and supporting the longitudinal end edges of the second retaining wall part in its water-retaining position.
    The struts can be connected to the first retaining wall part in a manner rotatable about a horizontal axis of rotation, wherein the struts, in their inactive position, extend over the top of the first retaining wall part, in particular form a cover, the axis of rotation being preferably transverse to the water-retaining side of the first retaining wall section. In the inactive position, the second retaining wall part included in the first retaining wall part can cover.
    In one embodiment the second retaining wall part comprises a number of retaining beams which can be received in the rest position adjacent to or lying flat on top of each other in the first retaining wall part and in the water retaining position stacked in a manner (such as a fence) form a retaining wall.
    In one embodiment, the length of the first retaining wall part is a multiple of the length of a second retaining wall part, wherein a subsequent series of second retaining wall parts is included in the first retaining wall part and pairs of struts are arranged in the area of the transition between adjacent second retaining wall parts inactive position in opposite directions and furthermore provided with means for coupling with each other.
    The second conductors discussed above and the embodiments thereof, in particular the construction of struts and second conductors as one movable whole, can also be applicable here.
    The first retaining wall part can be a fixed construction, in particular a stationary container, mounted on a quay or embankment or bank. .
    The base surface of the first retaining wall part is mainly, but not exclusively, a quadrangle. The quadrangular box-shaped first retaining wall parts can differ in design, for example, the side wall on the water side can be inclined, for example 80 degrees. The mutual formats can differ and the first retaining wall part can be formed with rectangles, with blunt and sharp corners, with possibly but not necessarily with two walls that are parallel to each other as with a parallelogram. By choosing the angles, the flood defense can be given a shape that deviates from it, instead of a straight shape, such as a zigzag shape or a stepwise curved shape to be able to follow the course of a meandering river. The invention offers a long moment arm in the width of the base surface, again with added structural value and a relatively high strength and a high safety factor that is an important objective of the design.
    The present invention is distinguished on essential points such as being rotatable about one fixed point of the proposed construction. This is of great importance in connection with the then possible laterally directed mountain position (in addition to half the height of the expansion position) in order to thereby provide an optimum free passage in the public space with the inclusion of the second retaining wall part in or on or on the side of the first retaining wall section has been placed, resulting in a limited influence on this (sometimes scarce) public space, including preservation of free passage and the view.
    The first retaining wall part may consist of, for example, an inverted box-shaped construction with a water-facing front and a rear-facing rear and has two end faces of which a vertically hinged structure may be placed in the vicinity of one side and at the opposite end side receiving or engaging parts are provided to receive or engage at least one ground anchor, also to enable a row with the requested length to be formed with comparable adjacent structures. The first retaining wall part can stand cold on a quay or subsurface in order to be able to be moved in various ways, including rotatable, sliding or liftable. At least one point of application is provided in the subsurface intended for water retainers to obtain and retain the retaining wall in the required position. Each of these ends has sufficient width of, for example, 50 cm. and therefore offers a favorable, long moment arm. The ends of the possibly box-shaped construction are of such a shape that the rotating movement of the body is not impeded by the opposite or by walls or walls.
    Where desirable, the ground anchor may consist of a cylinder which is internally provided with a compression spring around a draw shaft. At the surface of the quay or threshold a simple annular grip can be connected which is connected to this tension shaft connected to the compression spring. By inserting the point of engagement on the lower longitudinal side of the first retaining wall part in the said annular grip, the first retaining wall part can be coupled to the substrate, wherein during heavy loads or in the event of a shock the compression spring as a part of this ground anchor adds a certain resilient property to this fastening with which a adjustable ductility of the system becomes available.
    From one aspect the invention provides a retaining wall mainly as a flood defense which as a first retaining wall part is holder of a second retaining wall part, wherein this holder is movable or optionally rotatable about an axis located outside or within its own base surface, and wherein the holder is provided with guides provided with bracing means for guiding and retaining the second retaining wall part from the mountain position to the expansion position in order to thereby obtain a water-pressure-resistant position and wherein the first retaining wall part with - if required - the second retaining wall part in the expansion position - a flood defense can form in a passage or over a requested distance and in which a plurality of contiguous first retaining wall parts can be constructively coupled to the substrate and the second retaining wall parts can cooperate with each other in the expansion position, wherein the contiguous parts - with the front sides - mainly the side walls - are constructed in such a way that they i n together form an increased structural stability for the assembled retaining wall such that a relatively high safety standard is guaranteed at a high water level or a high load capacity. The aspects described above may apply separately or in combination.
    The aspects and measures described in this description and claims of the application and / or shown in the drawings of this application can, where possible, also be applied separately from each other. Those individual aspects and other aspects may be the subject of split-off patent applications directed to them. This applies in particular to the measures and aspects that are described per se in the subclaims.

    DETAILED DESCRIPTION OF THE DRAWINGS
    Figure 1 shows a base surface of the first retaining wall part 1 of a retaining wall 100 in an exemplary embodiment of a water barrier according to the invention, wherein the first retaining wall part 1 is intended to turn water for the land side 201b from the water side 102a and can be rotated for this purpose around a fixed pivot point or placed on a threshold 2 of an opening or passage in a dyke body, or on a quay, at ground level or in an opening or passage between or in structures.
    The first retaining wall part 1 is elongated with short sides 1 b, 1 d and long sides 1a (water side or wet side), 1c (dry or land side). On a first short side 1b, the first retaining wall part 1 is attached at the location of hinge 3 to a fixed wall 2c, of a fixed retaining wall or of a building. The hinge 3 forms a vertical axis of rotation, around which the first retaining wall part 1 is rotatable from the rest or storage position to the water retaining position. This pivot point 3 can be provided on the outside with 1 or be accommodated at a suitable location within the base of 1. To move the first retaining wall part 1 to the water-retaining position, that retaining wall part can be provided with a roller 3c on the underside, then a foot as a sledge. For the displacement of the first retaining wall part, this first retaining wall part can be provided with a drive. The roller 3c can optionally find a location inside or outside said ground surface along the radius 3a of pivot point 3, the roller 3c allowing movement of retaining wall 1 along circular circumference 3b. The pivot point 3 has a connection that must allow some degree of vertical movement during the displacement of the first retaining wall part. To this end, a wider bead or bushing is provided to the top of the hinge 3.
    In addition, a pipe 3d (Figure 1), which is closed in the short side 1d, offers a possible insert for an externally placed part of a lifting tool as an aid in turning the retaining wall.
    Figure 1 furthermore shows two ground anchors 5, half-length and full-length away from the hinge 3, on the water side. These ground anchors 5 can be constructed from a horizontal axis 5b around which a folding part 5a can be rotated. The folding part 5a can be equipped with a rotatable grip 5c. This grip 5c is provided with engagement openings which can couple to a provision in the first retaining wall part 1 to thereby make a coupling between the fixed world and the first retaining wall part 1. Depending on the expected loads, several ground anchors can be provided per retaining wall part. The ground anchor 5 can be biased to a coupling position and locked in the inactive position, lowered into the threshold 2.
    The first retaining wall part 1 is box-shaped and forms a cavity 1g. The long water side or wet side 1a and the second short side 1d are provided with brush-shaped material at the bottom to allow water into the first retaining wall part but to retain litter.
    In the proposed embodiment, the rising water can thus enter the first retaining wall part 1 to prevent floating up. To actually reverse the water, seals are provided on the long land side or dry side 1c and the first short side 1b at the bottom.
    Figure 2 is a horizontal cross-section of the first retaining wall part 1 with a second retaining wall part 6 accommodated in the cavity 1g in the rest position or storage position.
    On the inside of the short sides 1b, 1d, the first retaining wall part 1 is provided with vertical (first) guides 8a with which the rest position is held in place in the second retaining wall part 6 and which provide a vertical guide to the second retaining wall part 6 when it is raised or moved down.
    Figure 3 is a top view of the first retaining wall part 1 with a second retaining wall part 6 accommodated therein. Figure 3 shows shores 9 which are rotatably connected to the upper edges of the short sides 1b, 1d and form one rotatable whole with second conductors 8b, which are attached to the edges of the struts 9 facing the water side. As an illustration, a strut 9 is folded down in the left half of the figure, so that it covers the cavity 1g. The second conductor 8b then lies over the upper edge of the second retaining wall part 6. In the right half the strut 9 is folded up vertically, the second conductor 8b having come to lie vertically in line with the first conductor 8a there, so as to form one continuous conductor for the second retaining wall part 6. On the water side of the folded down second guides 8b the cavity 19 is covered by a fixed plate of casing 4 of first retaining wall part 1.
    In figures 2 and 3, for illustration, an end of a following assembly of first and second retaining wall parts is shown on the right-hand side. The ground anchor 5 at the location of the meeting of both first retaining wall parts has a double effect, namely engaging both first retaining wall parts 1. A seal 10a is provided between the two retaining walls.
    A coupling means 10a couples the adjacent struts 9 of the adjacent wall parts. This coupling means 10a can for instance comprise hooks which can engage in a passage in the pressure braces 9. The adjacent second conductors 8b can also be coupled to each other by a coupling means, in order to keep them together in the transverse direction (towards the water side and land side).
    Figure 4a shows a cross-section of an embodiment of the first retaining wall part 1 with the second retaining wall part 6 still in the storage position. The casing of 1 is provided with a bump 1k on the water side and a water seal 1e on the land side. An embodiment of the ground anchor 5 is here provided with a compression spring 5d. The first retaining wall part 1 in the expansion position is shown in the water retaining situation.
    In the case that the water level will rise further, the second retaining wall part 6 can be expanded to the required maximum retaining height, see figure 4b. The struts 9 are folded up and the second conductors 8b have come to line up with the first conductors 8a.
    Figure 4c is like 4b, now with an example in which the water-side longitudinal wall 1a of the first retaining wall part 1 is inclined, as a result of which the peak load in both wave stroke and collision by objects is limited by bouncing. The slope angle can be adjusted to local requirements. In this figure 4c an additional draw strut 9b is provided on the water side. Pressure brace 9 is here provided with the seal 1f for connection to a fixed wall or to the pressure brace of a subsequent second retaining wall part.
    Figures 5, 6 and 7 show an example on which the second retaining wall part can be brought into the expansion position with one and the same hoisting tool. The hoisting tool 13 is equipped with a winch and a frame 13a which is equipped with an extension arm 13b at the ends of which hoisting cables 13c are attached. The hoisting cables 13c extend through conductor eyes (third conductors) 8c at the ends of the second conductors 8b. (Figure 3) and are attached to the ends of the upper edge of the second retaining wall part 6. The working arm 13b can be adjusted in the working width to the length of the second retaining wall part. The expansion starts with the lifting of the two second conductors 8b. As soon as these have arrived in the vertical expansion position, the lifting / pulling force is released to raise the second retaining wall part, so that the vertical movement of the second retaining wall part starts (6a) until it has reached the expansion position 6b. In the expansion position, the second retaining wall part 6 can be secured by means (not shown). When the second retaining wall part 6 has to be put away again, the locking means are made inactive.
    Figure 8 shows the upper edge of the second retaining wall part 6 in the mountain position. This retaining wall part 6 lies within the circumference of the first retaining wall part 1 and, where present, is covered by the second conductor 8b with the connecting pressure strut 9. Also shown is a flexible O-profile 10b which is mounted within the second conductor 8b, which seal serves for sealing in case of water load in the expansion position. Furthermore, a solid profile 10 of semi-hard plastic is shown, on the water side of wall part 6. Figure 9 shows the situation in the area of figure 8 after the second retaining wall part 6 has been expanded. The chamfered lower edge of retaining wall part 6 presses on the profile 10 which is enclosed between the casing 4 and the lip 6c on the lower edge of retaining wall part 6. The tilted position of profile 10 shown is such that due to the lateral pressure on the lip 6c the second retaining wall part waterproofing against the seal 10a, which forms part of the housing 4, is clamped.
    Figure 10a shows a possible arrangement according to the invention in the rest position with a series of first retaining wall parts 1. The second retaining wall parts 6 are included in the first retaining wall parts 1, so that the height is limited. There is a passage 7a, 7b between the fixed water barriers 2e, for example for people who want to go from the landside 102b to the waterside 102a, or vice versa. The transit line, as a reference, is indicated by T and runs parallel to the water barrier to be realized. The retaining walls 1,6 are oriented transversely with respect to the passage and extend from hinges 3 in the direction of the landside 102b. At least one ground anchor 5 is placed along the threshold 2a, but several anchors 5 per length may be desirable or required. In the center is a column 2f which provides pivot point mounts 3 for two middle retaining walls 1.6. The height of this column 2f is the same as that of the flood defense.
    Figure 10b shows the situation in the case of active flood defense. The first retaining wall parts 1 are rotated through 90 degrees to close the passages 7a, 7b. The second retaining wall parts 6 are plotted for the maximum water retaining situation in which they connect to the fixed water retainer 2e and also to column 2f.
    Figures 11 a and 11 b show another arrangement according to the invention, in rest position, below, and in water-retaining position, above. The water barrier comprises a series of pairs of retaining walls 100a and 100b, each comprising a first retaining wall part 1 and a second retaining wall part 6. The retaining walls 100a are longer than the retaining walls 100b. The retaining walls 100a and 100b are rotatable about a common axis of rotation 3, which is located on the land side, in the rest position of Figure 11a. The angles x of the short sides of the first retaining wall parts 1 have been specifically selected in advance, tailored to the situation of use. With this it can be achieved that the angle on the land side in the case of the operating position, Fig. 11b, is smaller than 180 degrees, and as can be seen, a water barrier with a zigzag-like course can be obtained. The retaining walls Herewith, in conjunction with the choice of the length of the relevant retaining wall part, the flood defense becomes particularly suitable for an environment with variable wave directions Z including W1, 2, 3, 4 and the possibly changing loads therefrom. The composition of a retaining wall from several versions of the retaining wall parts (here short and long) offers the possibility of determining a favorable angle Y. The wave stroke can be settled and thereby moderated.
    For the waves coming from a direction of, for example, the open sea or from the length of a large river or from the length of a lake, there is a chance of a long wave with high peaks and a chance of relatively high dynamic loads. In such an environment, the impacts of the dynamic forces due to rolling and breaking waves can be influenced with the wave angle alignment and thereby reduced. This is possible in cooperation with a leading area 102b such as a land strip, wherein the base surface of the first retaining wall part is formed by straight, blunt and sharp corners or a choice thereof.
    Figures 12a-d show a water barrier according to the invention, wherein a first retaining wall part 1 is fixedly arranged on, for example, a quay and forms a series of trays separated by intermediate walls 1w in which a second retaining wall part 6 is each time stored. The second retaining wall part is therefore divided in longitudinal direction and also divided into partitions 6a-d in attainable retaining height. These lie in the rest position of Figure 12a in the receiving space of the first retaining wall part and are then completely covered by struts 9. At the bottom, the covering struts 9 are provided with a U-shaped guide 8. For each part length, second retaining wall parts 6 are two partitions 9, which are rotatable about a horizontal axis S near the ends of the stored second retaining wall parts 6a-d. This can also be seen in the schematic top view of figure 12d.
    When the flood defense must be active at a height above the first retaining wall part 1, the partitions 9 are folded upwards on either side, around two respective pivot axes S, and then upright partitions 9 lying next to each other are coupled to each other, so that their upright position is retained . Subsequently, the partitions 6a-d are taken out of the receiving space and lowered with the end edges guided by the guides 8. In the position of figure 12c, the guides 8 keep the partitions 6a-d in line with each other and in place. The water forces are transferred from the partitions 6a-d via the guides 8 and the partitions 9 to the intermediate walls 1w of the first retaining wall part 1.
    The first retaining wall part 1 can act independently as a flood defense between the water side 102a and the land side 102b. The first retaining wall part 1 offers several special advantages over the prior art because this first part, possibly in connection with one or more ground anchors, is calculated as an independent body to absorb peak loads. In addition, when the first retaining wall parts are placed in series, the base may contain varying angles and lengths and may therefore be suitable for heavier tasks than the standards on the market.
    The invention (s) is by no means limited to the embodiments shown and described in the drawings and description. The above description is included to illustrate the operation of preferred embodiments of the invention, and not to limit the scope of the invention. Starting from the above explanation, many variations will be apparent to those skilled in the art that fall within the spirit and scope of the present invention. Variations are possible of the parts shown in the drawings and described in the description. They can be used separately in other embodiments of the invention (s). Parts of different examples can be combined with each other.
