description

The invention relates to a dam device for protection against flooding and a method for building a dam device.

In order to protect buildings and facilities, extensive dams made of sandbags by fire fighters and helpers were piled up in the event of the flood disasters that had occurred in recent years, particularly the Elbe floods in August 2002. Such protective walls consisting of layered sandbags can, however, only be built up relatively slowly. There is also the problem that larger amounts of sandbags have to be filled in nearby sand pits and then transported to the place of use. Protective walls built from sandbags can only be kept stable up to a certain height. In the event of stronger impacts, such as those caused by objects carried by the flood, protective walls built up from sandbags are quickly destroyed.

It is an object of the invention to provide a dam device which can be constructed quickly and inexpensively and which offers reliable protection against flooding.

The object of the invention is achieved by a dam device for protection against flooding according to claim 1 and by a method for building a dam device according to claim 21.

The dam device according to the invention for protection against flooding has a first support structure and a second support structure arranged at a distance from the first support structure. In addition, the dam device has a ne large number of water chambers which can be filled with water and are arranged in the free space between the first support structure and the second support structure.

In the dam device according to the invention, the water volume contained in the water chambers is spatially fixed with the aid of the first and the second support structure so that this fixed water volume can serve as an inert mass of the dam device. Instead of sand, the abundant water available on site is therefore used as a “filler material” for producing a dam device of great mass and inertia. The components of the first and second support structures and the water chambers can be produced inexpensively. The components of the first and second supports - The construction and the empty water chambers require little storage space and can be easily transported to the place of use if necessary. The support structures are then set up at the place of use, the water chambers are inserted between the first and second support structures and filled with water The dam device according to the invention is also able to withstand stronger impacts, such as those caused by objects carried by the flood. A further advantage is that greater heights can be achieved with the dam device according to the invention than with a dam device layered from sandbags.

According to an advantageous embodiment of the invention, the first support structure is arranged on the outside of the dam device and the second support structure on the inside of the dam device. The width of the dam device is therefore determined by the two support structures. It is advantageous if the water chambers are spatially fixed by the first support structure and the second support structure. In this way, the water stored in the filled water chambers becomes part of the dam device.

According to a further advantageous embodiment, at least one of the support structures comprises a plurality of supports anchored in the floor. By anchoring the support structures in the ground, the dam device can withstand the flood.

It is advantageous if at least one of the support structures comprises a plurality of guide sleeves anchored vertically in the floor for receiving the carriers. The guide sleeves can be anchored in the ground beforehand. In the event of a flood, only the carriers have to be inserted into the existing guide sleeves.

It is also advantageous if at least one of the

Support structures, the beams are arranged at substantially regular intervals from each other. This ensures maximum stability.

It is advantageous if the beams of the first support structure are offset from the beams of the second support structure by a predetermined distance. A more even anchoring of the dam device to the ground can thereby be achieved.

According to an advantageous embodiment of the invention, at least one of the support structures comprises a plurality of baffle plates. The baffle plates protect the water chambers behind them from impacting objects. In addition, such a formwork improves the stability of the dam device The baffle plates are advantageously metal plates or metal sheets, preferably steel sheets. Metal sheets can deform elastically and in this way absorb shocks, such as those caused by objects swept away by the flood (tree trunks, parts of buildings, etc.).

According to a preferred embodiment of the invention, the carriers are designed to hold baffle plates. According to a further advantageous embodiment, the supports are double-T supports. Double-T beams are characterized by high stability, even with small profile dimensions.

It is advantageous if the baffle plates are inserted from above between two adjacent double T-beams. The profile of the double-T beam forms a holder for the baffle plate mounted therein.

In particular, it is advantageous if the baffle plates are mounted in the double-T beams in such a way that the baffle plates have a certain amount of play to absorb shocks.

It is advantageous if the water chambers can be filled individually with water. The section-by-section construction of the dam device can ensure that at most one section of the dam device is destroyed while the other sections can continue to perform their function. Under certain circumstances, the destroyed section can then be repaired again.

According to an advantageous embodiment, the water chambers each have a connection for a water hose, preferably for connecting a fire hose. The water chambers can be filled with water in a short time using a fire hose. It is advantageous if the water chambers are essentially cuboidal water chambers, the dimensions of which are designed such that the space between the first and the second support structure is essentially completely filled by the filled water chambers.

If the water chambers are dimensioned in such a way that the space between the first and the second support structure is essentially filled in a form-fitting manner, a good seal can be achieved. The stability of the dam is also improved.

It is also advantageous if the wall of the water chambers is made of flexible material. So the water chamber can adapt to the available space between the first and the second support structure and the

Seal the dam device to the floor and to the neighboring water chambers. In particular, it is advantageous if the wall of the water chambers consists of plastic or rubber, preferably of fabric-reinforced plastic or rubber.

After filling with water, the water chambers advantageously produce a seal from the floor and from adjacent water chambers.

It is advantageous if struts for stabilizing the beams are attached between beams of the first support structure and beams of the second support structure above the water chambers. In this way, buckling of individual beams in particular can be avoided.

The method according to the invention for the construction of a dam device for protection against flooding comprises the construction of a first support structure and a second support structure arranged at a distance from the first support structure, the introduction of unfilled water chambers into the space between the first support structure and the second support structure, and the filling of the water chambers with water. The invention is described below with reference to an embodiment shown in the drawing. Show it:

1 shows the dam device according to the invention. On the first side of the dam device there is a first support structure which is constructed from the beams 1, 2, 3, 4 and metal plates 5, 6, 7 anchored in the floor. The metal plates 5, 6, 7 are each arranged between two adjacent supports. A second support structure is attached to the second side of the dam device. arranges which supports 8, 9, 10 and metal plates 11, 12, 13, 14 arranged between the supports. To increase the stability, the carriers 8, 9, 10 can be arranged laterally offset from the carriers 1, 2, 3, 4. In the free space between the supports 1, 2, 3, 4 on one side and the supports 8, 9, 10 on the other side, water chambers 15, 16, 17 are arranged, the dimensions of which are such that the free space is as possible is completely filled out. The water chambers 15, 16, 17 can be filled with water via fill supports 18, 19, 20. As a result, a positive seal is achieved both to the floor and to the neighboring water chambers.

In the following, concrete dimensions for an embodiment are given as an example to give a clear impression of a possible dimensioning of the dam device. However, the dam device according to the invention can also be realized with dimensions that differ significantly from the dimensions specified below. In the embodiment of the invention presented, the carriers 1, 2, 3, 4 are arranged, for example, at a distance of 2.50 m. For example, double-T beams made of structural steel with a profile of 14 mm x 14 mm can be used as beams, which are known under the name IPB beams. In this preferred embodiment, the height of the beams measured from the ground can be, for example, 2 m. For the metal plates, which preferably also consist of structural steel, dimensions of, for example, 2 m × 2.45 m can result in this embodiment. With regard to the thickness of the metal plates, a sensible compromise should be found between not too high a weight of the plates on the one hand and sufficient stability on the other. The thickness of the metal plates can range, for example, between 4 mm and 15 mm. The distance between the first row of beams 1, 2, 3, 4 and the second row of

Beams 8, 9, 10 can be, for example, 0.60 m. For the water chambers, the walls of which are preferably made of made of reinforced rubber or fabric-reinforced plastic, dimensions of 2 mx 2.5 mx 0.6 m result, for example.

Fig. 2 shows the structure of the support structures in more detail. Guide sleeves 26, 27, 28 are introduced into the ground to anchor the supports 21 to 25. For example, 1.5 m deep holes with a diameter of 20 cm can be drilled using an earth auger to set the guide sleeves. Then the guide sleeves, which have an outer diameter of 16 cm, for example, are placed in the plumb line, and the hole is filled with sand, split, earth, concrete, etc. The carriers 21 to 25 can then be inserted into the guide sleeves if necessary, ie in the event of impending flooding. Next, the metal plates 29, 30,

31 inserted between two adjacent double T-beams from above. Thus, the metal plate 29 is held by the two double-T beams 21, 22, the metal plate 29 having a certain amount of play within the holders.

The support structures can be set up in a short time if you have a self-loading machine available. The use of a truck with a loading arm is particularly advantageous for inserting heavy metal plates.

Next, the water chambers are inserted from above into the space between the first and the second support structure and filled with water. A water chamber 32 with a filler neck 33 is shown separately in FIG. 3. The dimensions of the water chamber 32 are chosen such that the space between the support structures is essentially completely filled. The water chambers arranged one behind the other between the two support structures are able to fill the space between the support structures in a form-fitting manner. A quick filling of the water chamber can best be carried out with the help of a fire hose, in particular a C hose, such as is used, for example, to empty cellars. The filler support 33 is therefore preferably a bayonet lock for connecting a C hose (C connection). The construction of the dam device according to the invention is completed with the filling of the water chambers. However, braces can be added between the beams above the water chambers.

In Fig. 4, the dam device according to the invention is drawn in plan view. The first support structure comprises the supports 34, 35, 36, 37 and the metal plates 38, 39, 40. The second support structure comprises the supports 41, 42, 43 and the metal plates 44, 45, 46, 47. In the space between the first and the second support structure has water chambers 48, 49, 50. It should be assumed that the first support structure faces the flood, while the second support structure is on the side of the area to be protected. If, for example, the metal plate 39 is subjected to impacts, such as are caused, for example, by heavy objects carried along by the flood, such as tree trunks, furnishings, etc., such impacts can be absorbed by the dam device according to the invention by means of a plurality of operating mechanisms. The metal plate 39 is held by the profiles of the double-T beams 35, 36 with a certain amount of play. The profile cross-section of the double-T beam forms a front stop and a rear stop for the metal plate stored therein. Normally, the metal plates are pressed outwards by the filled water chambers, that is to say to the front stops of the double-T beams, as can be seen, for example, from the metal plate 38 shown in FIG. 4. In the event of an impact on the metal plate 39, it is pressed against the rear stops of the double-T supports 35, 36 into a new position 51. With stronger impacts the metal plate also deform according to the position 52 shown in FIG. 4. These two mechanisms of action can also absorb stronger impacts from the dam device in such a way that a dam break can be avoided. In a way, this is reminiscent of a crumple zone of a motor vehicle.

The associated section of the dam device would only be damaged if the plate 39 were very strongly deflected or the plate 39 broke. Because of the construction of the dam device in sections, the remaining sections would remain undamaged in this case as well. The damaged section can also be restored by inserting a new metal plate between the supports 35, 36. A new water chamber can then be introduced and filled to restore the original state.

FIG. 5 shows a cross section through the dam device according to the invention along the line AA ^r shown in FIG. 4. The filled water chamber 50 is fixed on the right side by the metal plate 40, which is part of the first support structure. On the left side of the filled water chamber 50, the carrier 43 can be seen, which is part of the second support structure. The carrier 43 is inserted into a guide sleeve 53 which has been set vertically and fixed with the aid of filler material 54.

The stability of the dam device according to the invention can optionally be further increased by struts attached above the water chambers. In particular, struts can be attached between the beams on one side of the dam device and the diagonally opposite beams on the other side of the dam device. An advantageous embodiment of such struts is shown in FIG. 6A. A connecting piece 56 is molded onto the ends of a rod 55 or in some other way

Attached way, which consists of two U-shaped elements 58, 59 connected to one another via a web 57. With help of the connecting piece 56, the strut can be pushed onto the upper end of a double-T beam 60.

The construction shown in FIG. 6A can also be used to brace a beam with two beams arranged obliquely opposite one another on the other side of the dam device. For this purpose, struts 61, 62 of the type shown in FIG. 6B can be used. First, the strut 61 with its connecting piece 63 is pushed onto the upper end of the double-T beam 64. The strut 62 can then be pushed onto the connecting piece 63 by means of its connecting piece 65. For this purpose, the distances between the two U-shaped elements of the connecting piece 65 are adapted to the dimensions of the connecting piece 63, as shown in FIG. 6B.

In FIG. 7, a top view is shown of how the dam device according to the invention can be built over a corner. Carriers 66 and metal plates inserted between the carriers are arranged along the inside of the dam device. There are supports 67 along the outside and metal plates inserted between the supports 67. The water chambers 68 are located in the free space between the inner support structure and the outer support structure arranged at a distance d. In order to be able to build over corners, additional metal plates 69, 70 of an adapted width are required. The width of the metal plate 69 results from half the distance between adjacent supports 66 minus the distance d. Correspondingly, the width of the metal plate 70 results from half the distance between two adjacent supports 67 plus the distance d.
