DE10237862A1 - Portable wall for use as flood barrier has wall modules consisting of triangular baseplates with two wall panels fastened together side-by-side and held in place by ground anchors - Google Patents

Abstract

Each wall module (1,2) consists of a baseplate shaped as an equilateral triangle, carrying two wall panels which may be at an obtuse angle to each other. The edge where the two panels meet faces away from the flood (8). The edge or corner (4) is reinforced at the top, and has an eye for a karabiner hook on a cable (5) with a tensioning screw. A karabiner hook on the other end of the cable is fastened to an eye on top of a ground anchor (6). A frame (3) on the base of each wall element carries a second ground anchor (9) which prevents sliding of the base of the wall. Each baseplate rests on a sealing sheet (7). Adjacent sealing sheets overlap, and the wall modules fit together side-by-side.

Description

1.) The invention belongs to protection against floods

2.) To the known state of technology count Coll the following protective measures:

• a) Dam beam systems with permanently installed posts Disadvantage: visible posts. Plug elements very expensive and not sealing.
• b) Barrier systems Disadvantage: Too many individual parts. You have to go to Waterproofing to be covered with foil and weighed down with sandbags.
• c) container systems made of plastic disadvantage: large Time spent setting up and filling.
• d) sandbag dams Disadvantage: High expenditure of time.

3.) The following problem was solved with the invention:

• a) No storage problems since stackable. A truck can be up to 150 meters protective length transport.
• b) Set up very quickly because it is easy and easy to connect. Two people switch approximately 1 km of protective length in 2 hours.
• c) Very dense due to overlapping firmly connected geomembranes.
• d) Safe against water pressure, because on the water side and land side secured in terms of tension and pressure.
• e) Can be bent at right angles through element arrangement.
• f) Factory production or prefabrication.
• g) Can also be used in the private sector because it is very inexpensive.

4.) Invention with problem solving

To the aforementioned problems to solve a) to g) an element was developed which is very light. An element weighs e.g. B. in material Glulam with a protective length of 1., 20 meters and one protection level of 1.20 meters approx. 30 kg. A sandbag is only slightly lighter.

The elements can be easily connected to each other, because the connections are always rectangular.

The element connections are made using screws or plug connections. A height adjustment the slope of the terrain given by the staggered arrangement of the connections.

The stability in the event of a crash and flotsam impact is due to pull ropes and pressure angles which is the Catch overturning moment and which is firmly attached to the ground with anchors connected are given.

Thanks to the trapezoidal sealing membrane firmly connected to the element is due to the overlap an extensive waterproofing is given.

Because the elements are triangular and they can only be stacked well on one side.

5.) Commercial use

The protection requirement is in all flood-prone Given areas. Construction companies, Precast plants, plastics manufacturers and handicraft companies participate.

6.) Beneficial effects of the invention in relation to the prior art

The previous state of the art sees no system, which the flood protection with so lightweight compact elements. No flood protection is included to store such a small space. The right angle bend the Protection line is not so easy in any system.

No other system has one waterproofing connected to the protective element.

No system can be set up so quickly.

No system uses this through a triangular shape Water weight for stability.

These elements can affect ice pressure and Impact of flotsam caused by the train protection and the tipping moment shift do not move.

7.) Execution route

In the earth on the land side become pointed tube sleeves struck into the grown soil 9.

As well; steel rods are inserted into the grown soil on the water side with a hinged eyelet 6 , Now the steel brackets with the welded plug pin 3 into the tube sleeve 9 plugged in. Then the right-angled protective elements including their sealing sheets 1 . 2 etc. to the steel angle 3 pushed up with its tip. Then the protective elements are firmly connected to each other at right angles to the water side by means of push-push or screw connectors. A corresponding height offset can be compensated for with the connections. Then the pull ropes with tensioner are attached to the previously opened corner reinforcement with eyelet using two snap hooks 4 and the earth thorn with eyelet 6 hooked and tense. Then the waterproofing membrane is weighted against floating due to the first water, with one sandbag per element or by means of a steel clamping rail.

Claims (5)

Flood protection device for protecting populated or agricultural areas from flooding, with triangular containers that are open and connected to each other on the water side 1 u. 2 etc. which achieve their stability due to the surface pressure caused by the water load and the shape-related shift of the tilt angle towards the land side, characterized in that: - the protective elements can be made of wood, plastic or steel and the tilting moment by an additional load arm 3 is intercepted towards the land side. Devices according to claim 1, characterized in that the tilt angle 3 has a welded-on thorn, which is hammered into a hollow earth thorn on the land side 9 is inserted to protect against overthrow. Devices according to claim 1 or 2, characterized in that there is a trapezoidal overlapping on the triangular base plate of the protective elements sealing membrane firmly connected to the element. Devices according to claim 1 or 2, characterized in that an additional stability train connection with tensioner 5 , is attached from the water-side upper element tip to the water-side earth surface and an earth rod with eyelet is hammered into the subsurface in a stable manner. Devices according to one or more of the preceding claims, characterized in that the connection between the individual protective elements 11 due to their right-angled arrangement, they can be manufactured with height-adjustable press-in connections or press-in screw connections.
