Abstract

A demountable flood protection wall has a modular construction with similar modules (1) connected by adjacent edges secured by seals. Each module comprises a base (4) an inner wall (3) an outer wall (2) and at least one cross wall (11) to form a trough shape. The module is braced by a triangular support (6) on the dry side which can be further secured by ground spikes (10) and which is removable or is hinged on the inner wall. The water side has at least one water inlet port (5) set above ground level and selectively closed by sliding shutters. The erected module can be filled with ballast.

Description

The The invention relates to a mobile flood protection barrier according to the preamble of Claim 1.

Such a flood barrier is in the DE 202 13 118 U1 been described. From this document is a mobile flood protection, consisting of transportable components that are waterproof coupled with each other known. The components have the shape of square wells that are watertight, fillable with water and emptied, the tub consists of a bottom wall with four side walls.

The Bottom wall has an opening to empty the tub. For partitions is also an opening to Water exchange between the cells formed by the intermediate walls provided.

Another mobile barrier for flood protection is in the DE 20 2007 003 224 U1 described. This consists of L-shaped moldings, each mold body consists of an upright rectangular wall and a ground facing away from the water side, adjacent moldings are watertight coupled together in the wall area, the bottom has a foundation plate or is connected to this area and between wall and Floor of each shaped body at least one connecting this support web is arranged.

Everyone moldings is at least partially formed as a hollow chamber, wherein the hollow chambers with water, sand or any other small-sized, bulked mass fillable are.

adversely in these composed of individual elements flood barriers is that they are static in terms of flood loads and therefore oversized for safety reasons.

The concerns in the case under discussion in particular the funds used for the Stability, namely the bulk material, Water or weighting parts.

Starting from the DE 202 13 118 U1 It is an object of the invention to provide a mobile, composed of individual elements flood control wall, which is adaptable, at least within limits to various flood loads.

Is solved This object with the features of claim 1, advantageous embodiments Subject of the dependent claims.

According to the invention is at a flood protection wall, which can be assembled from individual elements is, wherein the individual elements a floor, two opposite each other Walls and at least one of these walls have connecting connecting wall and fillable with load or loadable are provided, with the individual elements on the outside the opposite of the flood side Wall a support have the loads on the single element from the direction of Flood side intercepts and the wall on the flood side has at least one opening through the flood can flow into or out of the element. By this arrangement is guaranteed that with increasing flood this takes over the weighting function for the elements.

The Connecting wall or the connecting walls do not have to be with the outer edges the flood-side and -abseitigen wall complete, but can also be arranged offset in between these, so that the edges of the flood-side and / or the -abseitigen wall free stand. This is even advantageous for arranging connection means and / or seals between adjacent individual elements.

Further can in this room in a further embodiment, an adjacent Element used, provided that this in this area a fit one smaller cross-section. Preferred for this embodiment is a trapezoidal Well bottom provided. In this case, two elements can be a tub space form.

Further can to increase the element stability further stabilization struts between flood-side and -abseitiger Wall can be arranged.

In the flood side wall is the at least one opening of the Trough bottom arranged away and / or there are several openings at different heights arranged to the bottom of the tub.

In The initial phase with rising water levels are enough for the dead weight and possibly a ground anchorage for a stable position of the elements. As the water level rises, water flows in the elements and complains in addition.

A embodiment Provides that openings closed by a lid are. So z. B. retained in the element infused water be and an increased Weighting about a longer one Period of time to be maintained.

Such covers can be used as a slide or be arranged in the respective wall.

When supports on the outside the opposite of the flood side Wall, the first loads on the single element from the direction of Must catch the flood side, are preferred angle supports arranged with a connecting the angle leg support strut.

The supports are for Transport preferably detachable connected to the respective wall or can be tilted to this wall. Conveniently, feature the supports over ground anchors.

An embodiment is in 1 shown.

The flood barrier is made of individual elements 1 composable, wherein the individual elements 1 on the outside of the wall opposite the flood side 3 a support 6 have to absorb the stresses on the single element from the direction of the flood side and the wall 2 at least one opening on the flood side 5 owns, by the flood in the element 1 flows in and out. The at least one opening 5 is from the ground 4 arranged away.

The supports 6 are each as an angle support with an angle leg 7 . 8th connecting support strut 9 educated. In this case, the support strut 9 a triangular shape.

The support 6 is detachable with the wall 3 connected or adapted to this hinged. Furthermore, the support has 6 over ground anchor 10 , which are drivable in the soil and are pulled out during disassembly.

For the sealing of adjacent individual elements 1 . 1' Sealing strips have proven themselves, preferably with H-shaped cross-section, covering the edges of the walls 2 . 2 ' and 3 . 3 ' and the floors 4 . 4 ' overlap on both sides.
