Description

[0001] The invention relates to a water barrier device for holding back and / or diverting water, wherein the water barrier device comprises at least a first barrier unit and a second barrier unit, wherein the respective barrier unit comprises a wall element with a wall width, a wall height and a wall depth and a flat base element for placement on a floor, and the flat base element is connected at an angle to the wall element along the wall width and has a side exposed to the wall element.

[0002] Due to climate change, rising sea levels, and / or heavy rainfall events, local flooding is expected to increase in many areas. Flooding can also occur locally due to firefighting water runoff or burst water pipes.

[0003] Generally, permanently installed flood protection systems are known, such as a custom-fitted door barrier that can be inserted into a doorway. Furthermore, mobile flood protection systems are known, such as those consisting of stacked dam beams with seals inserted between them, which are slid into lateral support profiles from above. A disadvantage of known mobile or permanently installed flood protection systems is that they are often not quick and easy to assemble, nor can their spatial arrangement be adapted to the shape of the object to be protected and / or the course of the flood.

[0004] DE 10 2004 025 456 A1 describes a demountable dam wall with posts that can be anchored in the ground and with wall elements, each of which has a curved storage surface and a support foot projecting forward on the storage side. Each wall element has hinge elements distributed along one height of each of the two side edges of the storage surface. When the support feet of two adjacent wall elements are aligned, the hinge elements of both wall elements engage with each other, and to connect them, a separate hinge pin is then inserted from above through the hinge elements of both wall elements.

[0005] The purpose of the invention is to improve the state of the art.

[0006] The problem is solved by a water barrier device for holding back and / or diverting water, wherein the water barrier device comprises at least a first barrier unit and a second barrier unit, wherein each barrier unit comprises a wall element with a wall width, a wall height and a wall depth, and a flat base element for placement on a floor, and the flat base element is connected at an angle to the wall element along the wall width and has a side exposed to the wall element, and each barrier unit has a connecting rod at one end of the wall width aligned in its longitudinal dimension in a direction of the wall height, wherein the connecting rod has at least a partially internal cavity, and has a connecting pin at the opposite end of the wall width, wherein the connecting pin is arranged such thatthat the connecting rod of the first barrier unit with the internal cavity can be attached to the connecting pin of the second barrier unit, so that the two connected barrier units can be angled relative to each other by means of the connecting pin as an axis of rotation.

[0007] This provides a water barrier system that can be quickly and flexibly deployed using at least two barrier units to contain and / or divert water during a flood event. Consequently, the water barrier system is efficient and can be used in a targeted manner, adapting its layout to specific locations, for general property protection during various flood events, for protection against heavy rain, for retaining firefighting water, and as a road barrier to divert water volumes in the event of burst pipes.

[0008] It is particularly advantageous that the water barrier device, consisting of two or more barrier units, especially those of identical construction, can be assembled without additional aids and / or connecting elements and can be erected on a surface. Two consecutive barrier units are simply connected by inserting the connecting rod, which has an internal cavity, of one barrier unit onto a connecting pin of the subsequent barrier unit. The connecting pin simultaneously serves as an axis of rotation, allowing the connected barrier units to be angled relative to each other in their longitudinal orientations along the wall elements. Consequently, at each connection point, the spatial orientation in the longitudinal direction of the preceding barrier unit can be changed and / or precisely aligned by connecting the respective connecting rod to the respective connecting pin of two adjacent barrier units.Furthermore, in the assembled water barrier device, the spatial orientation of two connected barrier units can be changed easily and quickly by moving and rotating one of the two barrier units on the axis of rotation, without having to dismantle the barrier units.

[0009] Furthermore, it is advantageous that the barrier units of the water barrier system are simply placed on the ground and / or an area to be protected, with the respective flat base element resting at least partially on the ground and / or the area to be protected. It is also advantageous that the barrier unit and / or the water barrier system does not need to be fixed in or to the ground, for example, by means of an anchoring element. Instead, the water barrier system is specifically free of any fastening element in or to the ground. Because the free side of the flat base element faces the water, the water flows onto the top of the flat base element and presses it, and thus the respective barrier unit, against the ground, thereby preventing the water barrier system from slipping or being washed away.

[0010] A key aspect of the invention is that the length and spatial orientation of a water barrier device can be flexibly adjusted and aligned during assembly. This is achieved by attaching the connecting rod of the preceding barrier unit to the connecting pin of the subsequent barrier unit, particularly those of identical construction. Simultaneously, the connecting pin's design as a pivot axis allows the two connected barrier units to be angled relative to each other. Because the internal cavity of the connecting rod is guided around the upward-facing connecting pin during attachment, two adjacent barrier units can be quickly and easily connected without an additional connecting element. The following terms will be explained:

[0011] A "water barrier device" is, in particular, a modular system with two or more barrier units for holding back and / or diverting water. The water barrier device is constructed by connecting two or more barrier units to each other, thereby creating a protective wall against flooding, inundation, and / or water ingress. In this process, the internal cavity of the connecting rod of one barrier unit is inserted onto the connecting pin of the other barrier unit, creating a rotatable connection. The length of the water barrier device can be flexibly adjusted by selecting the appropriate number of barrier units. Due to the rotatable connection between the connecting rod and the connecting pin of each barrier unit, the water barrier device can be spatially aligned along its length, and thus along the width of the barrier units, within the terrain.This allows the water barrier not only to keep water away from a protected object but also to divert it in a controlled manner across the terrain. Since the connecting rod with its internal cavity is simply attached to the connecting pin, this rotatable connection can be easily disassembled. This makes the water barrier flexible and modular, and particularly mobile, allowing it to be set up, dismantled, and / or transported to various locations requiring protection.

[0012] A "barrier unit" is, in particular, a planar component that extends primarily in a vertical and a horizontal direction. The barrier unit comprises, in particular, a wall element and a base element. The barrier unit can be formed as a single piece, comprising both the wall element and the base element. Likewise, a wall element and a base element can be joined to form a barrier unit, whereby this connection can, in principle, be materially bonded, force-fitted, and / or form-fitted, as long as the connection point and / or line is watertight or sealed. A "wall element" is understood to be, in particular, a vertical planar component whose dimensions in width (wall width) and height (wall height) are greater than in depth (wall depth or wall thickness).A "ground element" is in particular a planar component which is essentially horizontally oriented and, when using the water barrier device, rests at least partially on the ground.

[0013] The barrier unit can, for example, be designed as an elongated plastic angle, thus having an L-shape in cross-section. In this L-shape, the wall element is positioned and connected perpendicularly to one side and / or edge of the flat base element, while the exposed side of the flat base element is oriented towards the water at the opposite edge. Alternatively, the wall element can be positioned and connected at any point in the cross-section between the opposite longitudinal sides of the flat base element. Therefore, the barrier unit can also have an inverted T-shape in cross-section, with the wall element pointing upwards. The barrier unit can be made of any material, such as wood, steel, and / or plastic. Preferably, the barrier unit is made of plastic, for example, polyethylene.The base element can have a rectangular and / or trapezoidal shape in plan view. Alternatively, the base element can essentially have a rectangular shape, with at least one side and / or edge having a conical shape.

[0014] It is important to emphasize that the barrier units do not necessarily have to be identical in construction; only the connecting rod and the connecting pin for the rotating connection must correspond to each other. Therefore, the barrier units can, for example, have different wall widths, wall heights, and / or wall depths, and / or be made of different materials.

[0015] The term "longitudinal direction" refers specifically to the direction of the longest extent of a body and / or component. Thus, the longitudinal direction is, in particular, the direction along the wall width of a barrier unit and therefore along the length of the water barrier device. In the case of the connecting rod, the longitudinal direction is, in particular, the direction along the length of the connecting rod. Accordingly, "longitudinal dimension" refers specifically to the longest dimension of a body and / or component.

[0016] The term "angled" specifically refers to the presence of an angle between the wall element and the floor element in the cross-section of the barrier unit. The wall element does not necessarily have to be perpendicular to or connected to the floor element. For example, the angle between the floor element and the wall element in the cross-section of the barrier unit can be as small as 30° to 90°.

[0017] A "connecting rod" is understood to be, in particular, a narrow, long component with a circular cross-section, which has at least a partial internal cavity. This internal cavity is connected, in particular, to an opening at one and / or the lower end of the connecting rod. The outer cross-section and / or circumference of the connecting rod is, in particular, circular or oval. The internal cavity of the connecting rod has, in particular, a circular cross-section. The cross-section of the internal cavity corresponds, in particular, to the shape and / or outer diameter of the connecting pin. For optimal design of the connecting pin as an axis of rotation, the connecting pin and the cavity of the connecting rod both have, in particular, a corresponding circular cross-section.In principle, the cross-section of the connecting pin and the cavity of the connecting rod can have any shape, such as triangular, square, hexagonal, or polygonal, provided that both are designed such that the connecting pin can rotate within the cavity of the connecting rod. The height of the internal cavity of the connecting rod is, in particular, at least slightly greater than the height of the connecting pin. Likewise, the diameter of the internal cavity of the connecting rod is somewhat larger than the outer diameter of the connecting pin. The connecting rod, for example, designed as a tube, preferably extends over the entire wall height or is slightly shorter than the wall height. This ensures that the outer surface of the connecting rod and / or tube seals the vertical edge of the wall element of the subsequent barrier unit with the connecting pin. away.Because the connecting rod and / or the pipe itself serves as a sealing element, the transition between two barrier units is seamless and does not require a separate sealing element. Due to the round or circular cross-sectional shape of the connecting rod and / or pipe, the vertically oriented wall element slides along the outside of the connecting rod, ensuring a near-complete seal at any angle and preventing the barrier units from tilting during spatial alignment. Thus, the water barrier device is watertight at every possible minimum angle of the connected barrier units, particularly between ±35°, preferably at least ±25°, due to its design.

[0018] A "connecting pin" is understood to be, in particular, a protruding component used to connect two barrier units. The connecting pin can be designed, in particular, as a round bar with a free, protruding end. The free end of the connecting pin is oriented, in particular, upwards. The longitudinal direction of the connecting pin and the connecting round bar is, in particular, parallel to the wall height. The connecting pin is, in particular, made of solid material. However, the connecting pin can also have at least a partial cavity within it. The connecting pin, as its axis of rotation, has, in particular, a lower height than the connecting round bar and / or its internal cavity. For example, the connecting pin can have a height of 30 mm and the connecting round bar with a continuous cavity a height of 200 mm.

[0019] The connecting rod and the connecting pin each comprise at least one material that is compatible with and / or connectable to the material of the wall element and the floor element, and thus to the respective barrier unit. Preferably, the connecting rod and the connecting pin comprise at least the same material as the wall element. Each barrier unit has only a single connecting rod at one end of its width, and thus along its side wall, and only a single connecting pin at the opposite end of its width, and thus on the opposite side wall. The connecting rod and the connecting pin are each firmly connected to the wall element and / or the floor element. In the case of a barrier unit made of plastic, the connecting rod and / or connecting pin can each be welded and / or bonded in place.In principle, however, a barrier unit can also be designed and manufactured in one piece, so that without an additional connection the barrier unit is manufactured directly with the wall element, the floor element, the connecting rod and the connecting pin, for example cast.

[0020] In another embodiment, the water barrier device has a third barrier unit, a fourth barrier unit, a fifth barrier unit and / or a sixth barrier unit and optionally further barrier units.

[0021] Thus, the water barrier device can be flexibly mobile in its length and spatial orientation on site according to the terrain and protection requirements.

[0022] A third, fourth, fifth and / or sixth and optionally further barrier unit is a barrier unit as defined above.

[0023] In order to allow two adjacent barrier units to bend along their wall width and thus to create a non-linear length of the water barrier device, a smallest angle with the associated axis of rotation as its apex can be formed between the two wall elements of the two connected barrier units in a range of 0° to 35°, in particular from 5° to 25°, preferably from 10° to 20°.

[0024] Thus, the course of the water barrier device can be optimally adapted to the spatial conditions of the terrain on site and / or designed to divert the water in a specific direction.

[0025] In another embodiment of the water barrier device, the respective attached connecting rod is designed with its outer surface to seal against the respective wall element with the connected connecting pin.

[0026] Thus, the outer surface of the connecting rod itself acts as a seal. The vertical wall of the next barrier unit slides circularly past the outside of the connecting rod, ensuring a near-complete seal at every bend angle. Consequently, according to the invention, a separate seal, which would otherwise be laboriously installed between the two adjacent wall elements when connecting the corresponding barrier units, is unnecessary.

[0027] To provide an optimally rotatable connection between two adjacent barrier units, the connecting rod can be designed as a tube and / or the connecting pin as a mandrel.

[0028] When the connecting pin is designed as a mandrel, the free end of the connecting pin has a tapered tip. This allows the connecting rod to be placed more easily and centrally onto the mandrel-shaped connecting pin.

[0029] In a further embodiment of the water barrier device, the barrier unit or barrier units have at least one foot element, wherein the at least one foot element is arranged under the wall element and / or the flat floor element, so that when the barrier unit and / or barrier units are placed on the floor, the respective exposed side of the floor element rests obliquely on the floor.

[0030] Beneath the wall element and / or a section of the base element, facing away from the water, a foot element or several foot elements, for example, a round foot, are arranged to position the respective barrier unit at an angle on the ground. This places the exposed side of the flat base element at an angle to the ground. Consequently, water can flow diagonally upwards from the water side across the surface of the base element towards the wall element. The foot element or foot elements on the underside of the base element, facing away from the water side, prevent the respective barrier unit from floating away by creating a negative pressure between the underside and top of the base element through the rapid escape of water between the underside of the base element and the top of the ground.Thus, the respective barrier unit adheres to the floor automatically.

[0031] In order to achieve a secure seal even with a large angle between two adjacent barrier units, the barrier unit or units can each have a joint cover element on the base element and / or the connecting round bar, so that when the two connected barrier units are angled, the joint cover element seals the joint between the two base elements of the two connected barrier units in a watertight manner.

[0032] Thus, even with large angles of inclination of the barrier units, a seal between successive base elements can be ensured by each barrier unit having a joint cover element on its base element and / or the connecting rod. For this purpose, the joint cover element can, for example, be welded to the connecting rod and / or the base element. The joint cover element can also be designed as a plate and widen conically on both sides towards the water side and thus towards the free end of the base element. The joint cover element preferably rests on top of the base element of the preceding barrier unit and, after the connection, also on top of the base element of the subsequent barrier unit. The joint cover element can have larger dimensions than the base element when oriented towards the water side.

[0033] In another embodiment of the water barrier device, a material reinforcement is arranged below the connecting pin, the spike and / or the base element.

[0034] To ensure optimal sealing and a defined sealing edge aligned with the water, even on uneven substrates, a sealing material can be arranged in front of and / or below the exposed side of the floor element(s) and / or an exposed side of the joint cover element.

[0035] Each floor element and / or joint cover element can have a sealing edge on its exposed side facing the water. To improve sealing against the ground, a sealing material can be arranged in front of and / or below the exposed side of the floor element and / or joint cover element. This sealing material could be, for example, a foam rubber or an elastomer seal.

[0036] The sealing material can also be a sealing membrane, which is attached beneath the respective barrier element, base element, and / or joint cover element. In this case, the sealing membrane can adapt to unevenness in the ground and improve the seal. The sealing membrane can, for example, be 80 mm wide and welded to the underside of the base element and / or joint cover element over a width of approximately 20 mm. To allow for visual inspection and functional monitoring, the sealing membrane can also extend forward, towards the water side, beyond the free edge of the base element and / or joint cover. For example, the sealing membrane can extend 20 mm beyond the free edge of the respective barrier element.

[0037] Additionally, each base element may have a hole or spaced holes across its width to attach the respective barrier unit and / or the water barrier device to enhance an existing protective system. An existing protective system might, for example, consist of hoses within a mesh casing, with the hoses filled with water to form the protective system. To enhance this protective system, the water barrier device can be attached to the top of the mesh casing, for example, using cable ties through the holes in the base elements.

[0038] In another embodiment, at least one stiffening element is arranged on the wall element and / or the floor element.

[0039] Therefore, to increase the stability of the respective barrier unit, one or more stiffening elements can be arranged on the barrier unit. For example, a stiffening angle is arranged in the transition area between a floor element and a wall element. The arrangement of stiffening elements and / or reinforcing elements on the barrier units is particularly advantageous when the barrier unit is manufactured from recycled plastic.

[0040] The invention will now be explained in more detail using an exemplary embodiment. Figures show... Figure 1 is a schematic top view of a first guide angle element of a water barrier device with a joint cover plate; Figure 2 is a schematic top view of the joint cover plate; Figure 3 is a schematic top view of a section of the water barrier device with the first guide angle element connected to a second guide angle element; Figure 4 is a schematic sectional view of a cross-section through the first guide angle element in the area of ​​a connecting pipe and the base of the first guide angle element; Figure 5 is a schematic sectional view of a cross-section through the first guide angle element in the area of ​​the middle of its width; and Figure 6 is a schematic sectional view of a cross-section through the first guide angle element in the area of ​​its connecting mandrel.

[0041] A water barrier device 101 comprises a first guide angle element 103. The first guide angle element 103 has a base plate 115, to which a wall 107 is perpendicularly connected on one side of the base plate 115. Opposite the wall 107, the base plate 115 has a free side 121. The base plate 115 and the wall 107 have a maximum width of 1,500 mm. The base plate has a depth of 300 mm. A connecting pin 125 is arranged at one end of the width of the base plate 115. There, the base plate 115 has a side perpendicular to the wall 107 in plan view along its depth ( Figure 1) which abuts the free side 121 perpendicularly. The corners of the base plate 115 are rounded. A connecting pipe 123 is arranged at one end of the width of the base plate 115 opposite the connecting mandrel 125. One side of the connecting pipe 123 runs along the depth of the base plate 115, tapering conically towards the free side 121 of the base plate 115. A joint cover plate 131 is connected to the connecting pipe 123 and the base plate 115, and partially rests on one upper surface of the base plate 115 ( Figure 1 and 4 ).

[0042] The joint cover plate 131 has a conically widening, essentially triangular shape with rounded corners extending from the connecting pipe 123 towards the free side 121 of the base plate 115. A recess 133 is arranged in the narrowest conical section of the joint cover plate 131, which surrounds the connecting pipe 123 ( Figures 1 and 2Furthermore, the base plate 115 has two spaced-apart feet 143 on its underside below the wall 107. Three spaced-apart stiffening brackets 145 are arranged across the width of the base plate 115 and the wall 107 in their transition area. The base plate 115 also has two spaced-apart holes 149 near the free side 121. A dowel reinforcement 141 is arranged below the connecting pin 125 and the underside of the base plate 115 ( Figure 6 ).

[0043] The water barrier device 101 has a second guide angle element 105 (as well as optional further guide angle elements) which is designed like the first guide angle element 103 described above.

[0044] The connecting mandrel 125 has a height of 30 mm, while the connecting tube 123 extends over the entire height of the wall 107, which is 200 mm. To connect the first guide angle element 103 to the second guide angle element 105, the connecting tube 123 of the first guide angle element 103 is placed onto the connecting mandrel 125 of the second guide angle element 105. Further guide angle elements (not shown) are connected in the same manner to increase the length of the water barrier device 101. When connecting the first guide angle element 103 with the second guide angle element 105, the alignment of the second guide angle element 105 along its width and thus along the wall 107 is bent by approximately 30° relative to the longitudinal alignment of the width of the first guide angle element 103 and thus of the wall 107 of the first guide angle element 103, whereby the second guide angle element 105 is aligned more towards the free side 121.Here, the joint cover plate 131 covers and seals a joint between the outer edges of the adjacent base plates 115 of the first guide angle element 103 and the second guide angle element 105 from above. Due to the feet 143, the free ends 121 of the base plates 115 of the first guide angle element 103 and the second guide angle element 105 rest obliquely downwards on the floor 117. A seal 147 is arranged in this area below the underside of the respective base plate 115.

[0045] In the event of heavy rainfall, rainwater flows from the open side 121 onto the top of the respective base plate 115 towards the respective wall 107. Due to the water pressure, the respective guide angle elements 103 and 105 are pressed against the ground. Simultaneously, despite the seal 147, at least some water penetrates between the underside of the base plate 115 and the top of the floor 117. This creates a negative pressure between the underside and the top of the respective base plate 115, and the corresponding guide angle elements 103 and 105 adhere to the floor 117 as a result, causing the water to quickly drain away from under the floor 115 towards the feet 143. A wedge-shaped widening of the joint between the underside of the base plate 115 and the floor 117, formed by the feet 143, ensures rapid drainage and creates a negative pressure.

[0046] Thus, a water barrier device 101 with guide angle elements 103, 105 is provided, which can be flexibly connected spatially and in a simple manner, placed on a floor without fastening means and used to hold back and divert water. Reference symbol list
