DE20109417U1 - Flood barrier from system boxes - Google Patents

Description

The most well-known water barrier consists of bags filled with sand that are stacked on top of each other to protect against flooding. Another flood barrier consists of a textile container system (hose system, HS container technology) that is filled with water.

problem

The problem with sandbags is that the bags and sand must be available in sufficient quantities and must be filled by a large number of helpers and brought to the site with extreme effort. In addition, the sand is contaminated with mud after the flood and must be disposed of at great expense. The HS container technology can only be arranged in one row and therefore cannot be expanded as the floodwater rises. After use, the textile hose must be cleaned on the inside with clear water (a valuable raw material) and must be absolutely dry to avoid mold and hardening when stored rolled up.

Solution

These problems are eliminated by the features listed in claim 1.

The invention achieves that by connecting and stacking several system boxes, a solid wall is created that can withstand high pressures and that can be further reinforced by building a second system chain if the flood continues to rise and the resulting higher pressures.

The conical system boxes are stored stacked inside each other and can therefore be brought to the site very quickly when needed with relatively little manpower. They can be quickly lined up next to each other and filled with water in just a few easy steps, even by untrained personnel, using the connecting pieces. The system boxes are coupled together at the openings with the connecting piece by clamping the connecting piece into the connecting frame and screwing or clamping it to the box using the fastening bracket. When a row is complete, it is filled with the incoming flood water and its increasing weight provides resistance to the flood. When the flood water rises, the boxes are closed with the lid so that another row of boxes can be stacked on top of them. This can be done in several rows, one on top of the other. The pressure from the upper rows of boxes, which in turn have to be filled with water, seals the lid watertight with the row of boxes below.

To further seal a box wall consisting of several layers, a tarpaulin made of tear-resistant PVC (fabric tarpaulin) can also be used. The tarpaulin is clamped to the boxes under the first layer and then pulled up layer by layer and anchored to the top layer.

When building multiple layers, the water pressure on the box wall can become so great that the connection between the boxes does not hold. In this case, a second wall can be built directly behind the first wall. This can be repeated as often as desired.

Another advantage of the invention is that the boxes and accessories are easy to clean and store after use. There is no need to ensure that the boxes are completely dry. The boxes can be stacked inside each other and thus stored in a small space.

The invention can also protect doors, gates, light shafts and exits from flooding. The fitting pieces are used to create a tight connection to walls and floors. Because the boxes can also be lined up at an angle, they can be used to remodel doors, gates, light shafts and exits.

In addition, the boxes can also be used to protect individual rooms from water entering the sewer system. To do this, the box is secured with the

The sealing ring to be attached is placed over the manhole cover and clamped to the ceiling of the building using the spreader.

An embodiment according to claim 1 is explained using figures 1 to 6. They show:

• Fig. 1 coupled system boxes

• Fig.2 and 3 the connecting piece

• Fig. 4 the system box with fitting pieces

• Fig. 5 and 6 the system box as a single element with accessories

Figure 1 shows the system boxes (1) made of sturdy plastic or other materials such as aluminum, fiberglass or PVC-metal connections with a lid (3) and connecting piece (2).

Figures 2 and 3 show the connecting piece made of tear-resistant plastic or plastic fabric cover (2) with the two aluminum connecting frames (4) and the connecting mechanism (5).

Figure 4 shows the use of the box with fitting pieces (6). The fitting pieces are made of the same materials as the system box or of rubber or rigid foam.

Figure 5 shows the use of a system box according to protection claim 12 with sealing ring (7) as a fitting piece over a gully grate (8).

Figure 6 shows the use of a system box according to protection claims 14 and 15 with an accessory made of metal or plastic and adjustable in height (9), as well as the sealing ring (7).

Claims (16)

1. Water barrier against flooding, consisting of system boxes which can be connected, stacked and combined as a modular system and can be expanded with accessories and fittings with existing buildings or parts of buildings. - characterized , - that the conical and thus stackable system boxes ( 1 ) made of stable plastic or other materials such as aluminum, fiberglass or PVC-metal compounds can be lined up one after the other through openings on the opposite sides by means of the connecting pieces ( 2 ) to form a container system that is variable in length and height, can be filled with water and is leak-proof. 2. Water barrier according to claim 1 - characterized, - that the boxes can be manufactured in any size from 500 mm (H) × 500 mm (W) × 1000 mm (L) to 3200 mm (H) × 3260 mm (W) × 5000 mm (L), preferably as a standard size 750 mm (H) × 990 mm (W) × 1770 mm (L). 3. Water barrier according to claim 1 - characterized, - that the system boxes can also be connected at right angles by placing the opening on the left or right side of the system box. 4. Water barrier according to claim 1 and 3 - characterized, - that the connecting pieces ( 2 ) are made of a tear-resistant plastic or plastic fabric material. 5. Water barrier according to claim 4 - characterized, - that the connecting pieces ( 2 ) are attached to the sides of the system box by means of a connecting frame ( 4 ). 6. Water barrier according to claim 5 - characterized, - that the connecting frame ( 4 ) is made of aluminium, hard PVC or other stable materials. 7. Water barrier according to claim 5 and 6 - characterized, - that the connecting piece is screwed or clipped to the system box using a fastening bracket ( 5 ). 8. Water barrier according to claim 7 - characterized, - that the fastening bracket is designed as a screw or clip mechanism. 9.
