    FLOOD DEFENSE DAM STRUCTURE WITH A CONNECTION, DAM COMPRISING SUCH STRUCTURE, AND METHOD FOR PROVIDING A DAM
    The present invention relates to a flood defense structure that can be used to assemble an entire flood defense dam. Such dam structure can be filled with water or other liquid, and can be used in case of an expected flood, for example caused by heavy rain falls or increase of sea (or river) water level.
    In practice, sand bags are used to protect a house or a dyke in a case or an expected flood. Such sand bags are relatively expensive and require a large amount of labor for filling and positioning the sand bags. Also known are box banders that can be positioned such that a dam is provided. In addition to the relatively high costs associated with these barriers, also storage room is required.
    NL2011435 discloses a flood defense dam structure from a flexible material having an inlet configured for filling a chamber with a liquid such as water. Such an individual dam structure comprises different parts or elements that require assembly. Individual dam structures need to be carefully positioned to provide an effective flood defense dam. This requires careful operation under difficult circumstances when a flood is expected or when there are heavy rain falls, for example.
    The objective for the present invention is to provide a flood defense dam structure that obviates or at least reduces one or more of the above stated problems and particularly provides a dam structure that is easier to use when assembling a flood defense dam and provides an effective dam .
    This objective has been achieved with the flood defense dam structure according to claim 1.
    The liquid chamber of the dam structure can be filled with a liquid, such as water. This chamber extends between two ends of the dam structure in a lengthwise direction. When filled with water the dam structure provides a dam element. Several dam elements can be connected together to achieve a flood defense dam.
    By providing the chamber from a flexible material, the required storage room or storage space can be kept to a minimum when the flood defense dam structure is not required. This reduces the storage costs of the dam structure according to the present invention. By providing an inlet that is configured for filling the chamber with a liquid, such as water, the chamber of the flexible material or the dam structure can be easily filled with a liquid to reach its desired shape and mass.
    According to the present invention a connecting element is provided at or close to at least one of the first and second ends of the chamber. The connecting element is configured for connecting the flood defense dam structure to another adjacent flood defense dam structure. This allows building or assembling an entire flood defense dam from a number of individual flood defense dam structures. The length of an individual dam structure may vary between the length similar to a opening and a length or up to 1000 meters or even more.
    The connecting element comprises a connecting surface area. The adjacent flood defense dam structure can be placed on this area. This provides an effective means to place ends or adjacent dam structures close to each other, with the respective ends engaging each other. This prevents leakage between two adjacent dam structures. The connecting surface area preferably comprises anti-slip material or elements. This further improves the connection or two adjacent dam structures.
    Preferably, the dam structure comprises a bottom surface that acts as a specific floor element of the dam structure. Such bottom structure contributes to maintain the position of the dam structure, also in case forces are acting on the dam structure. Furthermore, twisting of the dam structure is prevented.
    In a presently preferred embodiment according to the invention, the dam structure comprises two liquid chambers that extend substantially parallel to each other along a longitudinal axis from the first to the second end, the liquid chambers are spaced apart from each other in a direction substantially perpendicular to a longitudinal axis, and the liquid chambers are both connected to a common bottom wall.
    Having two liquid chambers that are spaced apart from each other while sharing a common bottom wall has several advantages about the prior art. First of all, manufacturing the dam structure having two chambers that are connected via a common bottom wall is more cost-effective and efficient than manufacturing a dam structure having a single chamber. Furthermore, providing two separate chambers that are connected via a bottom wall provides additional stability and strength compared to a dam structure having a single chamber or dam structure having an internal separation wall. Even if one of the chambers is damaged and leaking, the other chamber remains operational to provide time for switching or repairing the dam structure.
    In an embodiment having two parallel spaced apart chambers, each of the chambers is provided with an inlet configured for filling the chamber with a liquid, the connecting element is a single element connected to both chambers.
    In an embodiment according to the invention, the dam structure is manufactured from a single piece of material, preferably a single piece of material from which the chamber or chambers are folded.
    The dam structure according to the invention can advantageously be manufactured from a single piece of material to reduce manufacturing costs and time. Additionally, less raw material is required to manufacture the dam structure, since the material is used more efficiently. Preferably, the single piece of material is folded into a chamber, after which the walls are connected to each other, for example using welding, glueing, stitching or any other suitable method. Especially advantageous is to manufacture the dam structure from Ethylene Propylene Diene Monomer (EPDM), which can easily be folded and welded into the desired shape of the dam structure.
    In a preferred embodiment, in which the dam structure has two separate chambers having a common bottom wall, it is equally more preferable to manufacture the dam structure from a single piece of material. Outer ends of fhe single piece of material are folded inward and shaped to form of the chambers, after which the outer end is connected to the common bottom wall, for example using welding, glueing or another suitable connecting means that provides a durable sealed connection. By providing a space between the two chambers the chambers can be formed, shaped and subsequently connected to the common bottom wall more easily. In addition, the space provides for a more stable and resilient dam structure.
    Both the single chamber version and the dual chamber version of the dam structure according to the invention can be combined with vary or the invention as described below.
    In an embodiment of the invention in which the dam structure comprises two liquid chambers, a distance between oppositely positioned side walls or adjacent liquid chambers may be in the range or 0.05 meters to 2.00 meters, and may be preferably in the range or 0.05 meters - 1.00 meters, and may be more preferably in the range or 0.25 meters to 0.50 meters.
    Providing a specific distance between the opposite walls or two adjacent liquid chambers has several advantages. Preferably the distance is adapted to the (other) dimensions of the dam structure and / or to the specific user demands of the dam structure. A greater distance between the two chambers reduces the amount of material that is required for manufacturing the dam structure, whereas an increasing distance may also lead to a dam structure that is insufficiently strong and resilient for the required function. Therefore, the distance should preferably be adapted to the other dimension of the dam structure, such as the length, height and width as well as the intended use. Preferably, the distance is chosen to be in the range or 0.05 meters to 2.00 meters when the width of the dam structure is between 1.33 and 2.66 meters, although other dimensions of both the distance between the chambers as well as the dam structure as a whole fall within the scope of the invention as well.
    In a presently preferred embodiment of the invention the least one of the first and second ends is provided at an angle to a vertical plane.
    By providing at least one end of the dam structure at an angle to a vertical plane the watertight engagement or two adjacent ends is significantly improved. In one of the presently preferred, the angle is in the range or 1 ° to 15 °, more preferably in the range or 1.5 ° to 10 ° and most preferably the angle is about 5 °. Experiments have shown that such angle significantly contributes to the performance of the dam and the dam structures.
    It will be understood that the actual angle may depend on the overall size of the dam structure. In one of the presently preferred extender the upper surface of the flood defense dam structure has a length extending between the first and second end of the chamber that is larger as compared to the length of the lower surface of the flood defense dam structure that is in use rests on a ground surface. This assures an effective engagement or two adjacent ends or two adjacent dam structures. Experiments showed that the watertight connection when providing this angle is significantly improved, continuously improving the overall protection achieved with the flood defense dam structure.
    In the presently preferred embodiment of the invention the connecting element comprises a fastening element that is configured for releasable connection of the flood defense structure to an adjacent flood defense structure.
    By providing a releasable fastening element the connection can be improved, improving the aforementioned effects or an improved watertight connection between individual flood defense dam structures.
    In one of the invention of the invention, the fastening element comprises Velcro to enable an effective and easy to implement connection between two adjacent flood defense structures. In an alternative embodiment, the fastening element may comprise a number of grommets or eyelets. This allows fastening the connecting element using a rope, cord, cable or other element. In a presently preferred embodiment the dam structure comprises both fastening elements.
    In a further preferred embodiment according to the present invention the dam structure comprises a partition wall division at least two sub-chambers in the liquid chamber.
    By providing a partition wall the effect of the dam structure is improved. Preferably, the partition wall extends in a substantially lengthwise direction of the flood defense dam structure, more preferably in a substantially vertical plane. This improves the stability and strength of the flood defense dam structure.
    Optionally, in one of the preferred possibilities of the invention the partition wall is provided between two sub-structures that tire U-shaped. Preferably, open sides of the U-shaped sub-structures or sub-chambers are directed towards each other and the partition wall separates the two sub-structures. The components of such a dam structure are preferably sealed against each other, for example involving a hot-bonding process or other suitable process.
    In a further preferred embodiment according to the present invention the inlet comprises a non-return valve. By providing a non-return valve filling the chamber of the dam structure is made easier and it is prevented that a liquid leaves the chamber in an uncontrolled manner. This improves the filling process when installing the dam structure according to the present invention.
    Preferably, the non-return valve can be manipulated to enable removing the liquid from the chamber. Alternatively, or in addition thereto, a separate outlet can be provided.
    In a presently preferred embodiment the flexible material comprises Ethylene Propylene Diene Monomer (EPDM). Experiments showed that this material is effective, relatively easy to repair, not very sensitive to UV, and requires minimal maintenance. Alternatively, or in additional thereto, other materials can be used, such as PVC or TPE for example. Also, inserts or filaments or other material such as polyester can be included in the EPDM material or alternative material to improve the tensile strength. This further improves the overall performance of the dam structure.
    In a further preferred embodiment of the invention the flood defense dam structure is provided with a ratio between a height of the structure and a width of the structure that is in the range of 1: 4 to 2: 1, and preferably is about 1: 2. Experiments it has been shown that this ratio provides an effective dam structure.
    In an embodiment according to the invention, a height of the dam structure is in the range of 0.50 to 2.00 meters, preferably in the range or 0.67 to 1.33 meters.
    The dam structure can be provided in different heights to accommodate for different situations. Moreover, the available heights are preferably chosen to be multiples, i.e. having a dam structure of 0.67 meters and a different one or 1.33 meters. These particular dimensions provide a relatively easy to handle dam structure that can be filled relatively quickly and is equally usable for small floodings. By combining multiple dam structures, the dam structures can also be used in larger floodings.
    In an embodiment according to the invention, a width of the dam structure is in the range or 1.00 to 4.00 meters, preferably in the range or 1.34 to 2.66 meters.
    The width of the dam structure is preferably adapted to the expected use of the dam, such as the expected water pressure that will be exerted on the dam and dam structures.
    In an embodiment according to the invention, a length of the dam structure is in the range of 1.00 to 10.00 meters, and is preferably substantially 5.00 meters.
    It is found that a length of the dam structure or substantially 5 meters is effective in that it is relatively easily transportable and fillable.
    In an alternative embodiment according to the invention, a length of the dam structure is in the range of 10 to 10,000 meters.
    For specific situations, for example protection against flooding or a river or sea coast, it is preferred to have longer dam structures, which can be placed quickly, such as rolling along a river bank or sea coast.
    In an embodiment according to the invention, the inlet is flush-mounted with respect to the surface of the dam structure in which it is placed.
    The advantage of having a flush-mounted inlet is that damage to the inlet from placing adjacent dam structures is substantially prevented. Furthermore, an improved connection between adjacent dam structures can be obtained when the inlet is flush-mounted.
    In an embodiment according to the invention, the dam structure is provided with an outlet that is positioned in a bottom surface of the dam structure and that is connectable with an inlet or a second dam structure on which the dam structure is placed such that both dam structures are simultaneously fillable. It may also be possible to provide a dam structure having two outlets, each outlet is connectable to an inlet or a different second dam structure that is placed underneath the dam structure.
    The dam structure according to this embodiment is configured to provide a dam that the number of filling operations can be reduced due to the fact that multiple dam structures are in fluid connection with each other. This also makes it possible to connect the inlets and outlets or a number of unfilled dam structures in a stack to each other and fill that stack with liquid in a single operation. As a result, the filling time of the dam is reduced.
    In an embodiment of the dam structure, the dam structure comprises one or more of a number of sensors configured for measuring physical parameters within the chamber, a transmitter for sending and / or receiving signals to an external transmitter and a chip, preferably a computer chip , for providing geolocation and / or for processing signals from and to the sensors and / or transmitter.
    In use, especially during emergency situations, it is preferred that the operational status or the dam structure is measurable. This may for example include measuring a fill level and / or a pressure within the chamber to detect leakage and may also include providing a geolocation of the dam structure. Preferably, the dam structure is provided with multiple sensors for measuring a diversity of physical parameters indicating the operational status of the dam structure, which information is processed and provided to an external receiver for processing. This allows continuous remote monitoring of larger numbers of dam structures, for example dam structures in an emergency dam. As a result, a leak or failure of a dam structure, for example in a dam, may be detected at an early stage such that the leak can be repaired and damage to the surroundings may be diminished. The present invention also relates to a flood defense including a number of flood defense structures as described.
    The flood defense dam provides the same advantages and effects as described for the flood defense dam structure. Especially the connecting elements achieve a watertight connection or two ends or two adjacent dam structures engaging each other. This effect is further increased by providing one or both edges at an angle relative to the vertical.
    Ί
    In an embodiment of the flood defense according to the invention, it may comprise a number of drive plates that are positioned on an upper surface of the dam for providing an emergency walk- or driveway.
    The flood defense dam according to the invention can advantageously used to provide both a flood defense dam as well as an emergency road or path along which people may be evacuated. The flood defense only needs to be provided with drive plates, which are placed on an upper surface of the dam structure.
    Moreover, if the dam structures forming the dam are filled with another fluid, for example a gas or a liquid that floats on water, the dam can also be used to form an (emergency) bridge to cross bodies of water. This may for example be used in a situation in which a flood defense dam according to the invention is used, after which a number of dam structures is filled with air, provided with drive plates and is connected connected to the flood defense dam to form a bridge to allow the evacuation of people and / or other living beings.
    The bridge as described above may also be used alone and without a combination with a flood defense dam according to the invention as described above.

The dam-bridge structure according to the invention may be used in conjunction with one or a combination of the expires that are disclosed in reference to the flood defense dam structure.
    In an embodiment of the dam-bridge structure, the connecting element comprises a connecting surface area, whereon the adjacent dam-bridge structure is placeable.
    The adjacent dam-bridge structure can be placed on this area. This provides an effective means to place ends or adjacent dam-bridge structures close to each other, with the respective ends engaging each other. This prevents leakage between two adjacent dam-bridge structures. The connecting surface area preferably comprises anti-slip material or elements. This further improves the connection or two adjacent dam-bridge structures.
    Preferably, the dam-bridge structure comprises a bottom surface that acts as a specific floor element of the dam-bridge structure. Such bottom structure contributes to maintain the position of the dam-bridge structure, also in case forces are acting on the dam-bridge structure. Furthermore, twisting of the dam-bridge structure is prevented.
    In an embodiment of the dam-bridge structure, the dam-bridge structure further comprises a drive-deck connecting element for connecting drive plates to the dam-bridge structure.
    Preferably, the dam-bridge structure is configured with a drive-deck connecting element for securing drive-plates to the upper surface of the dam-bridge structure to provide increase the safety of the driveway on the bridge.
    As mentioned above, the invention also relates to a bridge including a number of connected flood defense structures or dam-bridge structures according to the invention.

As such, inwardly facing chamber walls 613a, 613b are positioned opposite each other and form a slot-formed opening. Similarly, chamber 606 is further provided with upper surface 610b, end walls 616b, 618b, and outwardly facing wall 612b. Chambers 604, 606 are connected to each other with bottom wall 614, which in this example is an integral part of both chambers. Each chamber 604, 606 is provided with its own respective liquid inlet 620a, 620b. Dam structure 602 is also provided with a connector 124 for connecting dam structure 602 with an adjacent dam structure 602. In this example connector 124 is formed as a foldable flap that extends from end walls 616a, 616b outwardly (see figure 6b). Connector 124 may be an integrally formed flap or may be a separate flap that is connected to dam structure 602.
    A second dam structure 602 can be placed in the U-shape form of connector 124 after which the end parts of connector 124 are folded around dam second structure 602, thus forming a solid and substantial water-tight connection that substantially prevents water from flowing or seeping through the connected dam structures. The present invention is by no means limited to the above described preferred elsewhere. The rights sought are defined by the following claims, within the scope of which many modifications can be envisaged.
