Description

Flood control reservoir

description

The invention relates to a device for the flood protection, in particular a reusable, fillable container for the flood protection.

In the event of flooding, areas with or without built-up areas often have to be protected from the rising water. This is usually done by impermeable barriers with a very large mass or weight. On the one hand, it can be an existing facility such as firm dams or dikes. These facilities can only be created with great effort and are therefore only suitable for areas at risk of flooding.

On the other hand, they are limited in time

Flood protection devices, for example in the form of sandbags, when this is required. In this case, a very high use of materials and labor is necessary in order to build up correspondingly high barriers. On the one hand, considerable amounts of sand, if possible already filled in sandbags, must be available. This can already have significant storage problems bring oneself. On the other hand, there are considerable transport problems, since considerable amounts of sand have to be transported to the place of use and put in position there. At the place of use, the sand, if it was not already filled in sandbags, must be filled into sacks. The handling of the sandbags to erect the barrier requires considerable effort due to the heavy weight of the bags. After use, the sand bags or after labor-intensive emptying of the bags, the sand has to be removed again with considerable effort. In addition, the sand is often contaminated after use and has to be disposed of as special waste.

Similar problems occur, but in a very limited form, e.g. B. also in the discharge or collection of extinguishing water in fire brigade operations if extinguishing water does not get into the sewage system or the ground, but is to be collected on an area for later disposal.

As an alternative, flood protection systems are known which consist of two parallel plastic hoses lying side by side, which are lashed together by strong belts. The hoses have two filling connections on the top and two drain connections on the side at the bottom. For assembly, the hoses are first filled with air using a small blower and then connected to the belts in the longitudinal direction so that the joints meet. After the hoses have been brought into the desired position, they are filled with water. The filled hoses inevitably have a circular cross section. Although these hose barriers are easier to store, erect and remove than sandbag barriers, they also have certain design-related disadvantages.

Due to the circular cross-section, the tube wall forms a gusset in the bottom area with the substrate. Water flowing in the lower area against the container wall is therefore pressed into the gusset area and thus towards the support surface of the container. On the one hand, this can easily lead to underflushing, on the other hand, a back pressure is created in the most leaky support zone, which makes it easier for water to seep under the container. Furthermore, because of the circular cross section of the containers and the parallel arrangement for a given barrier length, very large amounts of water have to be pumped into the containers in order to achieve a predetermined dam height. Finally, in order to achieve sufficient tightness and stability, two containers arranged in parallel and lashing together are necessary, which on the one hand entails increased costs, but above all also entails a more complex structure.

The object of the present invention is therefore a

To provide a device for flood protection, which is easy to store, transport and can be used without great effort.

The object is achieved by a container with the features of claim 1. A container according to the invention, which can be filled with a liquid or a fluid, has flexible, watertight outer walls, hereinafter referred to only as "tight", tightly connected to one another. Inside the container are at least partially chamber inner walls connected to the outer walls, which divide the inner space formed by the outer walls into chambers. The chamber inner walls are shaped and connected to the outer walls so that the container filled with a liquid or a fluid takes a predetermined shape. The chambers are arranged adjacent to one another. When filled with water, the container without the inner walls of the chamber would first be flattened due to its flexibility due to the weight of the water, and later, in the largely filled state, would be formed into a tube with an essentially elliptical or circular cross section. Due to the shape of the chamber inner walls and their connection to the outer walls, the chamber inner walls absorb tensile or shear forces caused by the liquid or the fluid in the container and thereby hold the outer walls in a certain shape.

The present invention also relates to a method for erecting a flood barrier, which comprises the steps: laying out a container according to the invention in the empty state and filling the container with water or a fluid. Here, the container can already be pre-filled with a water-curable material, for example a hydraulically setting cement, so that a permanent protective device is created by filling with water or another liquid.

Another object of the present invention is the use of a container according to the invention as Water retention device, in particular as a flood protection device.

The inner walls of the chamber according to the invention now make it possible to give the containers according to the invention a non-circular shape which is better adapted to the requirements, as is otherwise only possible with solid barriers or sandbag barriers. Compared to the simple hose barriers, this also eliminates the need for a parallel arrangement of two containers to be lashed together and the associated disadvantages.

The idea of providing the necessary weight of the flood barrier by means of a liquid to be filled in only when it is used, preferably water, and at the same time giving the barrier a desired shape through the interaction of the structure of the container according to the invention and the liquid contained in it during use, leads to solid barriers or sandbag barriers for several advantages:

On the one hand, the mass of the barrier does not need to be transported, but only the empty and therefore comparatively light container, since there will always be water at the place of use for filling the container, for example water from the water, which is at risk of flooding.

On the other hand, the empty container is ready for use because the outer walls are flexible, pack small and requires little storage space.

Furthermore, the container can be easily ^' laid out before filling, and is thus with very little work and to put effort into position.

Finally, the removal of the barrier is very simple since only the water has to be drained from the container. The empty container can then easily be folded again, if necessary after cleaning. It is then easy to dispose of or can preferably be reused. The problem of storing sand as special waste is eliminated.

The container according to the invention is therefore also very suitable for use in the private sector, since storage in a cellar or shed and the erection of the barrier are easily possible in the event of use.

Another advantage of the container according to the invention is that, when it is filled with water, it adapts very well to unevenness in the subsurface, despite its dimensional stability, due to the flexible outer wall, and thus provides a good seal.

If the container is filled with a fluid, for example a curable or hardening substance, a permanent protective device can be easily produced from the flood protection barrier. For the purposes of the invention, the term "fluid" includes not only liquid and gaseous substances but also low-viscosity to high-viscosity liquids, such as, for example, hardening materials, such as concrete, cement or hardening resins, which give the flood protection device its own shape stability after hardening or hardening, but nevertheless allow easy filling of the respective chambers. The outer walls of the container are made of a dense, flexible material that can absorb sufficient tensile forces and is preferably robust against external mechanical influences, so that it can absorb the tensile forces through the liquid or fluid filling on the one hand and not simply through pointed stones in the subsurface on the other is damaged.

Oil-resistant materials are preferred because, on the one hand, in

Floods can contain oil residues, on the other hand the containers can come into contact with oil during storage and / or use and could otherwise either be weakened in their strength or even leak.

The materials for the outer walls can be sufficiently strong foils, but fiber-reinforced foils or, particularly preferably, plastic-coated fabrics, in particular PES fabrics with a PVC coating on both sides, are preferably used. Corresponding materials are known to the person skilled in the art. This

As composite materials made of fibers or fabrics and plastics, outer wall materials have a very high tensile strength combined with water impermeability and a relatively low weight, whereby fabrics in particular have particular strength due to their structure.

The outer walls can be formed by interconnected flat material pieces or webs or by a hose in connection with material pieces as end faces. A plurality of outer walls are preferably formed by a material web, since there are some outer wall connections which generally represent a weak point and additional ones Processing steps are not required.

The watertight connection of the outer walls can e.g. by gluing or preferably welding. The welded connections by high-frequency or

Ultrasonic welding or using hot air or a hot wedge.

For this purpose, the outer walls preferably have connecting or welding tabs along their edges. After the connection, the flags are particularly preferably inside the container, since this results in the forces occurring due to the liquid in the container being distributed more favorably over the connection.

The chamber walls are preferably also made of a flexible material, so that the whole container can be folded very small.

The inside walls of the chamber can also be connected to the outside walls by gluing or welding. For this purpose, they preferably have two connecting tabs on each edge that is to be connected to an outer wall by gluing or welding, which are folded for connection on both sides of the wall and connected to the outer wall.

Along at least one edge, the chamber inner walls can also preferably be attached to eyelets that are attached to the at least one corresponding outer wall. For this purpose, they particularly preferably have eyelets arranged along the corresponding edge of the eyelets of the corresponding outer wall. The connection between the eyelets is then carried out using suitable eyelets running connecting means such as rings,

Plastic strips that are T-shaped at their ends with flexible

Legs are formed, or preferably carabiners.

Materials for the chamber inner walls that allow welding to the outer walls are particularly preferred. They are also particularly preferably oil-resistant, since they too could be damaged by oil in flood water used as a filling.

The interior walls of the chamber serve, as stated above, primarily to shape the container filled with a liquid in connection with the liquid.

To absorb the forces, the chamber inner walls are preferably connected to the outer walls on at least two, particularly preferably opposite, sides.

The chamber inner walls are preferably aligned essentially parallel to one another, since this results in a more favorable absorption of the forces that occur.

The container can be made in practically any length, but is preferably elongated. In this case, the chamber inner walls are preferably designed and with the

Connected to the outer walls that the container in the filled state on a flat surface with its longitudinal axis parallel to the surface so that at least one lateral outer wall of the filled container is inclined towards the bottom area. "Inclined" means here and in the following that the surface is inclined as a whole, but may still have, for example, vertically extending sections or roundings on the lower or upper edge; under "Filled" is understood to mean "filled with a liquid". As a result, the center of gravity of the filled container is lower, so that the water pressure from high water or waves cannot easily tip it over. Furthermore, waves hitting the side outer walls are partially directed upwards on the inclined side wall and thus exert less forces on the side outer walls. This can also result in the risk of under-flushing occurring in containers with a circular cross-section and possible leakage problems on the bottom surface, and at the same time the relatively high level

Water requirements can be avoided. Neither do two barriers have to be set up one behind the other in order to achieve the necessary tightness.

To achieve such a shape e.g. Chamber walls are used which have a triangular shape as the basic shape. A trapezoidal shape is preferably used, the chamber walls on the two non-parallel sides being at least partially connected to the outer walls. "Basic shape" is intended to mean that bulges or connecting lugs may still be present on the edges of the shape. The shapes mentioned have the advantage that the chamber inner walls can be produced in a simple and material-saving manner and can be processed easily.

In a further embodiment of this type, the chamber inner walls are designed and connected to the outer walls in such a way that the container in the liquid-filled state can be set up on a flat surface in such a way that a lateral outer wall which runs in the longitudinal direction in the direction away from the surface has an increasing inclination towards the surface having . Due to the increasing steepness of the lateral outer walls of the filled container, a better idle running of waves.

In the filled state, depending on the connection of chamber inner walls with the outer walls, between the subsurface and the outer wall resting on the subsurface along the connection of the chamber inner walls with this outer wall, channels can form in that these connected areas of the outer wall compared to the non-connected areas due to the liquid pressure be raised. Depending on the surface, water can seep through the barrier. For better sealing between the substrate and the filled container, the chamber inner walls therefore preferably have at least one bulge on the side facing the substrate during use, along which the corresponding outer wall is not connected to the chamber inner wall, so that the outer wall of the liquid-filled container has a profile along this side with at least one bead. The inner wall of the chamber, in particular its bulge, is designed such that the bead that is formed continues so far away from the inner wall of the chamber that it channels between

Interrupts the subsurface and this resting outer wall and thus prevents the water from seeping through or flowing. The tightness is further increased by several beads along a connection.

In a particularly preferred development, in which the inner chamber walls are connected to the outer wall resting on the substrate by means of eyelets and suitable connecting means, as mentioned above, for example, the part of the outer wall of the container which forms the bottom region in the filled state has at least one, preferably at least five rags running in the longitudinal direction and pointing inward into the container with the spacing of the inner chamber walls therein inset eyelets. The tabs can be, for example, welded welding tabs from sheets forming the bottom part of the container or, preferably because of the simpler processing and increased security against leaks, welds (ie welded folds) of the material web serving the bottom area of the container. The edge of the inner chamber walls opposite the base region then has eyelets opposite the eyelets in the tabs, which are connected to one another with suitable devices, such as rings or preferably carabiners. This design of the container bottom and the chamber inner walls has the advantage that, in the filled state, longitudinal ridges are formed between the lobes, which lead to a further improved sealing against leakage of water under the

Pass the barrier. Furthermore, the bottom of the container is no longer raised as much along the lower edges of the chamber inner walls, which also increases the tightness.

A container according to the invention can have at least one filling device for filling with liquid in an outer wall for each chamber that is tightly separated from other chambers; this is preferably attached in the upper part of the outer wall when filled.

The filling device can be a simple one in the outer wall, e.g. B. act by welding, recessed closure with a removable lid, which also allows the connection of a hose. For this purpose, e.g. B. all closures known to those skilled in the art with screw or

Bayonet locks are used. In particular, connections for garden hoses or fire hoses can be provided. The filling device preferably has a valve with a connection piece for connecting a hose, so that after the filling has been completed, the container can be closed before the hose is removed.

In order to accelerate filling, a container according to the invention has at least one venting device for venting the chamber during filling for each chamber that is tightly separated from other chambers. This can also be a filling device that is not used for filling and is then opened.

For easier emptying after use and for cleaning, a container according to the invention preferably has at least one tightly closable drain opening for draining liquid contained in the container, for each chamber which is tightly separated from other chambers.

The chambers of the container can be used except when connecting

Chamber inner walls and outer walls must be sealed against each other by means of eyelets. This has the advantage that only one chamber loses its liquid content if an outer wall is damaged.

However, several chambers of the container are preferably connected via openings in the chamber inner walls. This has the advantage that, on the one hand, fewer filling devices are required, and, on the other hand, that when the outer walls are loaded in the area of a chamber, pressure equalization between the chambers is possible, which increases stability. So that the liquid can be quickly distributed from the chamber with the filling device to connected chambers during filling, the total area of the openings of an inner chamber wall is preferably larger, particularly preferably many times larger than the area of the inlet openings of the filling device.

For air transport between chambers that are not sealed against one another when filling the container or in the case of a container that is only partially filled, individual or all corresponding inner chamber walls have openings in the upper region adjacent to the outer wall of the container when the filled container is set up.

In order to be able to create longer barriers, the containers according to the invention are advantageously designed at their ends in the longitudinal direction so that a plurality of containers, preferably essentially water-impermeable, can be connected to one another, which is preferably achieved in that the container has at least one end in one filled state lateral outer wall has devices for substantially water-impermeable connection of the container to a corresponding device having adjacent container.

This can e.g. B. done in that the container has at the ends in the longitudinal direction at least along one of the edges in the filled state extending from the surface upward flags for a roll connection. To connect, the flags only have to be placed one on top of the other, rolled up and fastened to the containers with one another or with their ends. Alternatively or in addition, the connection can e.g. B. also be done in that the container at one of its ends in the longitudinal direction at least over the entire length of the edge of the lateral outer wall in the filled state in the longitudinal direction

Have flags with eyelets and on the other side at corresponding locations on or in the outer wall insertable fastening elements, in particular rotatable toggles, for fastening the flag of a container to be connected.

In both cases, the flags can preferably run around the front edges of the container, thereby ensuring a double seal against water that presses against the barrier. This also ensures a better mechanical connection of the containers.

Preferably, on the end faces of the containers, e.g. be attached to flags, zippers in order to connect the containers to one another along their end faces. To relieve strain, connecting tabs with eyelets are attached to at least one outer wall on the side when filled; a rope, preferably a steel rope, is tensioned through these eyelets on adjacent containers for strain relief.

The connecting tabs are preferably attached to two opposite, side walls in the filled state in order to ensure a more secure connection. The end walls of the container can be pressed against each other by the rope tension, which additionally leads to an improved seal between the containers. To barriers also in non-linear form, e.g. B. to be able to create a polygon, in a special development serving as a corner container container at least one end in the longitudinal direction of the filled container an end

Have outer wall that is not perpendicular to the longitudinal direction. It is preferably designed so that it is substantially perpendicular to the ground when the container is filled. By connecting to another container, a change in the direction of the barrier can take place.

A container suitable as a corner container preferably has container outer walls shaped in such a way that the filled container has two linear sections or legs which are angled relative to one another. This will make a much larger one

Stability against the forces occurring in the corner and pushing apart the individual legs of the water acting on the container from the outside is achieved.

In order to exclude a displacement or tipping over of the container due to the water pressing on the filled container from the outside, a container according to the invention in a further advantageous development along its longitudinal direction has flags attached to an outer wall so that when the container is filled, it has heavy weight

Objects for fixing the container are heavy. As a result, a further sealing of the boundary layer between the substrate and the filled container is achieved. The flags preferably have anchor eyelets which are used for fastening to the floor by means of fastening anchors.

The invention is described below on the basis of preferred embodiments and first of all with reference to FIG. 1.

In Fig. 1, an elongated container according to the invention has outer walls 1 to 6 made of oil-resistant PES fabric coated on both sides with polyvinyl chloride (PVC) with a

Panama 2/2 binding. For this purpose, two end-side outer walls 1 and 2 in a trapezoidal shape are provided with two side outer walls 3 and 4 and one bottom-side and one upper outer wall 5 and 6 connected at their edges. The lateral outer walls are also connected to the bottom and the upper outer wall, so that there is a waterproof container shell. The walls 3 to 6 can also be formed by a tarpaulin sheet so that only a welded connection is necessary.

The outer walls are connected to each other by welded joints. For this purpose, the outer walls, as shown in FIG. 2 for the front outer wall 1, have welding tabs (7 to 10). The welding lugs lie inside the container to ensure greater strength. The weld seams must be designed so that they can absorb the mechanical loads, here the widths of the weld seams are e.g. between 4 and 8 cm.

Three closable filling devices, of which only the two openings 11 and 12 are visible in FIG. 1, to which a hose can be connected, are welded into the upper outer wall. Depending on the application, these are connections for garden or

Fire hoses. For filling at least one of the openings, e.g. B. 11, remain open for ventilation.

An emptying device 13 in the form of a screw cap, via which the container can be emptied, is also welded into the lateral outer wall 3 of the container facing away from the water during use.

As shown in the schematic sectional view of the container parallel to the substrate in FIG. 3, chambers are formed in the interior at regular intervals parallel to one another and to the end outer walls Chamber inner walls 14 welded, of which only one is shown in Fig. 1. They absorb the outward forces that occur when the container is filled with water and hold them together so that the container takes on the desired shape when it is filled with water. In contrast to the schematic view, the areas of the outer wall between two weld seams of adjacent inner chamber walls usually bulge outwards.

As shown in Fig. 4, the basic shape of the inner wall 14 is a trapezoid, which results in a substantially trapezoidal cross section of the container when the container is filled. The chamber inner walls have welding tabs 15 to 17 along the side edges and the bottom edge. More precisely, two welding lugs are provided for each of these edges, which protrude on both sides of the chamber inner wall 14. 5 these are shown for the flag 15; the first flag 15 is formed by a folded piece of the inner wall; a second welding lug 15 'is connected to the

Chamber inner wall with a high-frequency weld seam shown hatched in FIG. 5 formed flaps.

The welding tabs 15 and 15 'can also be extended beyond the respective side edge of an inner wall 14. By means of a further connection, secured in the longitudinal direction on the inside of the outer wall, such that the extensions of the welding lugs 15 and 15 'lie between the outer wall and the further connecting lug, the strength can be further increased or the connections of the inner walls 14 to the outer wall can be substantially strengthened become. In principle, the container can have almost any size, insofar as the chamber walls have sufficient strength. A preferred embodiment has, for example, a height between 30 cm and 150 cm, preferably between 50 cm and 110 cm, when filled.

A multiplicity of uniformly distributed openings 18 are punched into the chamber inner walls, which enable a water quantity compensation between adjacent chambers. Each individual opening has at least the same cross-section as a filling opening 11, so that the large number of openings means that the water can be quickly equalized at any time. Openings are preferably arranged on the bottom edge, so that a water quantity compensation can take place in the first stage of filling. The outer wall here is connected to the inner chamber wall only in the straight parts of the side, but not the bulges. This results, as shown schematically in FIG. 6 in a sectional view of the container transversely to the longitudinal direction near a chamber wall, in the case of filled containers along the side at the unconnected areas 19. FIG. 7 is a detail from a side view of a filled barrier shown. In the area of the chamber inner wall, whose lateral connection to the outer wall 6 is indicated by the dashed lines, the bottom-side outer wall 6 is raised, as a result of which 6 channels with a gusset-like (essentially triangular or trapezoidal) cross-section form between the base and the outer wall. These are blocked by the beads 19, which are shown hatched in FIG. 7 and extend transversely to the channels. This means that water can no longer pass through the barrier along the channels pass.

The upper edge of the chamber inner wall is not connected to the upper outer wall and has an indentation 20. As a result, air residues that collect in the upper part of the container during filling can move along the longitudinal direction of the container, so that on the one hand they can escape more easily through the ventilation opening and on the other hand a pressure equalization between chambers if the container is not completely filled, especially at

External pressure can only take place on individual chambers, as a result of which the container is exposed to low peak loads.

A particularly preferred second embodiment of the invention is shown in FIGS. the inside walls of the chamber are not welded to the bottom of the container, but are connected to it by means of carabiners. Parts that correspond to those of the first embodiment are denoted by the same reference numerals and are not described in more detail below.

As shown in FIG. 8, the container bottom 6 'of a container according to the invention has a plurality of longitudinally extending bottom tabs 21 with eyelets 22 embedded therein. As shown in Fig. 9, the tabs are made by welding the bottom of the container. Chamber inner walls 14 ′ are welded to the container outer walls 3 and 4 and are essentially designed like the chamber inner walls 14. As shown in FIG. 10, however, they have a straight hem 23 with eyelets 24 which are arranged at the same distance from one another as the bottom flaps 21. The eyelets 22 in the bottom flaps of the container bottom are arranged that the inner chamber walls are connected to the container bottom 6 'by carabiners 25 guided into the eyelets 22 of the bottom tabs and the eyelets 24 of the inner chamber walls. The height of the chamber inner walls is designed so that its hem 23 ends about 6 cm above the floor. This type of connection between the tank bottom and the chamber inner walls enables a very simple and cost-saving production. In addition, in the filled state, six beads form between the bottom flaps or next to them due to the fluid or fluid pressure, which provide an improved seal

Leakage of water between the tank bottom and the underground.

The chamber inner walls 14 'also lack the indentation 20 of the chamber inner walls 14 of the first embodiment.

The container also has a flag 26, which is attached along the edge between the container bottom 6 'and the lateral outer wall 4 of the container over the entire length of the container and has stamped-in anchor eyelets 27 through which fastening anchors can be placed in order to prevent the container from slipping. The flag is preferably arranged on the water side of the container. In this case, such a flag also prevents the barrier from being washed under by rapidly flowing water.

To connect a plurality of containers, the containers have zippers 28 welded on their end faces and holding loops 29 with eyelets 30 welded onto the outer walls 3 and 4 near the ends. Steel cables 31 are tensioned through the eyelets 30 of the holding loops 29 of adjacent containers in order to relieve the strain on the zippers, as shown schematically in FIG. 11. The type of connection described is of course also possible for containers according to the first embodiment of the invention, that is to say with chamber inner walls welded to the container bottom.

FIG. 12 shows a sectional view, parallel to the subsurface, of a third embodiment of a container according to the invention, which can serve as a corner element. It may vary with regard to the type of connection

Inner chamber walls with the outer walls e.g. act on containers according to the first or the second embodiment. The container has the usual chamber inner walls 14 or 14 '. A front outer wall 32 is angled at an angle of 45 ° with respect to the longitudinal direction of the container, the outer walls being shortened accordingly in the longitudinal direction.

13 shows a fourth embodiment of a container according to the invention, which can serve as a corner element, also in a schematic sectional view, in which two linear container sections with chamber inner walls 14 or 14 'are arranged at an angle of 90 ° to one another. The longitudinal outer walls of the right-hand container part have extensions 33 which extend beyond the last chamber inner wall 14 ″ and are connected to the corresponding outer walls of the other container part.

In a fifth embodiment, special corner containers 34 are used to create kinks in barriers. As schematically shown in plan view in FIG. 14, these have a trapezoidal plan. In the example shown, the end faces are in opposite to the short side of the container arranged at an angle of 135 °, so that in combination with normal containers with end faces arranged perpendicular to the longitudinal direction, for example according to the first or second embodiment of the invention, there is a 90 ° angle in the overall course of the barrier. Depending on the

Requirement that the water side be the short or long side of the tank. In the latter case, the end faces of the corner container are advantageously pressed against the end faces of the other barriers by the water pressure, which leads to a particularly stable and tight connection.

In order to have this advantage in the case of convex barrier profiles, kinks are formed from three types of containers in a sixth embodiment. In this case, as shown in FIG. 15, the end faces of the side containers 35 have an angle of 135 ° or greater with respect to the longitudinal direction of the container. The corner element 36 is again rectangular or trapezoidal with corresponding angles, but now the long side of the trapezoid lies on the inner side of the kink. Water on the inside will therefore press the corner container 36 against the side container 35, which in turn achieves a particularly stable and tight seal between the containers.

A fastening device for the lateral fastening of at least two containers to one another is described in more detail below with reference to FIGS. 16 and 17.

The cross-sectional view from FIG. 16 runs in a plane that extends in the direction of the longitudinal axis X of two containers 35 fastened to one another. The fastening device 37 comprises a profile strip 38, which defines lateral, outwardly open chambers 39, 40 for receiving thickened ends 41, 42 of flags 43, 44 of both containers.

For a better understanding, FIG. 17 shows a perspective view of the two interconnected containers 35 and the arrangement of the fastening device 37.

By means of the fastening device 37, a fixed connection can be created before the container 35 is filled by pushing the profile strip 38 over the thickened ends 41 and 42. This provides a tensile connection between the containers, which is defined by filling the containers 35 below one

Tension is set, which is already sufficient to create a watertight connection between the containers 35 so that no more flood water can pass between the containers 35.

If the container is filled with a fluid, for example a curable or hardening substance, a permanent protective device can be easily produced from the flood protection barrier.

In the following, reference is made to FIG. 18, which shows a further preferred embodiment of the invention in a schematic cross-sectional illustration.

18 has two longitudinally extending inner chamber walls 14 ''', which are welded to the outer wall 50 on both sides by connecting lugs 17. The one that extends in the longitudinal direction In the filled state, as a result of the chamber inner walls 14 ″ ″, which likewise extend in the longitudinal direction, at least, as shown, an essentially round cross section in the outer chambers. Furthermore, the chamber inner walls 14 '''are lower in height than that

Total height of the container when filled, so that the container has at least two support points 51 in cross-section, one on each outer chamber, and consequently the stability against rolling and / or undesired displacement is increased.

However, it should be pointed out that, depending on the area of use, an inner chamber wall 14 ″ ″ may be sufficient with regard to the desired stabilization of the filled container. In principle, however, the stability increases by increasing the number of inner walls 14 '' 'running in the longitudinal direction.

The connecting flags are expediently designed as double keder flags, so that one side 17a of the flag 17 can be fastened with a chamber inner wall 14 '' 'and one side 17b of the flag 17 with the outer wall 50. Furthermore, depending on the design, they can be glued, sewn or otherwise connected to the outer wall.

Due to the special shape of the container according to FIG. 18, in comparison to trapezoidal containers, extremely long containers, for example up to 50 meters or 100 meters, can be produced with considerably less material. The embodiment according to FIG. 18 is therefore particularly inexpensive. The external dimensions, such as the circumference, height or length of the container can be varied as in the previously described embodiments. With regard to the material used and its processing, this applies accordingly in relation to the embodiments described above. The filling and / or emptying devices are also designed accordingly, in particular as a screw cap, Storz connections, taps and the like. Furthermore, containers according to FIG. 18 can be connected to one another in a corresponding manner and a plurality of openings can be provided on the chamber inner walls 14 ″ ″ to compensate for the filling material.

Finally, the invention also includes embodiments in which holding devices on the for additional, in particular targeted positioning or fastening

Container outer wall are attached. Such holding device are practically arranged near the floor and can be provided in particular in the form of belt straps attached to the outer wall with eyelets, in particular in the form of semicircular rings, through which, for example, anchors, wedges or pegs can be driven into the floor. Such straps can be fastened to the outer wall in a manner corresponding to fastening the connecting lugs.

Belt straps attached to the outer wall are also suitable for packaging emptied containers, which in this case can be fixed in a space-saving manner in a correspondingly folded or rolled form with the belt straps, particularly for transport or storage.

In addition, it is within the scope of the invention a receiving device with a roller or a drum such to provide that empty containers according to the invention can be rolled up or wound onto the roll or drum for transport or storage.

When the containers are rolled or unwound from the drum for the intended use of the containers, the containers can also be filled automatically. In particular, it is provided for this purpose that a hose for filling the container, which can be connected to the container to be unwound, is arranged on the transport device.
