Description

Description HYDRAULIC FLOOD PROTECTION WALL

1.) The invention relates to protection against flooding . 2.) The known state of the art currently includes the following protective measures:

a) Retention areas

Disadvantage: loss of building land, only limited agricultural use.

b) River straightening

Disadvantage: Little protection against flooding. Damage to the water balance.

c) Earth dams

Disadvantage: Disturbance in the landscape. High maintenance costs.

d) Concrete safety walls

Disadvantage: Disturbance in the landscape. High construction costs.

e) Folding walls

Disadvantage: At a flood height of approx. 5 meters, 5 meters of plastic path, disturbing optical image. Joint formation susceptible to failure. Maintenance

intensive.

f) Transportable elements

Disadvantage: Storage is problematic. High time expenditure in the event of a disaster.
3.) The following problem was solved with the invention:

a) Area of operation in particularly cramped residential areas and landscape areas worthy of protection.

b) Constant operational readiness even without flood warning.

c) Manually controllable wall height in case of flood forecast by hydrant or pump pressure support.

d) Flexible height extension using telescopic element.

e) Possibility of right-angled or oblique bends of the dam line.

• · ♦

f) Possibility of connection to building walls.

(g) Factory production or prefabrication.

h) Can also be used in private areas (garden fence)

i) Extension of use as a cycle path or pedestrian path.

j) Lifeboat landing stage

k) Variable optical cover design

I) Construction on existing earth dams

4. ) Invention with problem solution

In order to solve the above problems a) to I), the pressure head or buoyancy that occurs in the event of flooding was used. The buoyancy force corresponds to the weight of the displaced liquid. (Archimedes' law.)

It is a closed system which is filled with water from the receiving water in the event of flooding and is raised vertically by one or more hydraulic rams (floating bodies). This buoyancy can also be generated manually by pump pressure or a hydrant connection. The depth and width of the concrete trough and the dimensions of the hydraulic ram (s) are determined by the desired protective wall height and the difference between buoyancy and load.

5. ) Commercial use

The need for protection exists in all areas at risk of flooding. Construction companies, precast plants, plastics manufacturers and craft businesses can participate in the creation of the system.

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

The current state of the art does not provide a system that combines flood disaster protection with the aesthetic requirements necessary for the human eye. If the covering is designed accordingly as a walkway, flower bed or meadow path, the system is not visible in the event of low water levels.

7.) Execution path

and construction
After excavation is complete, an earth trough with a water channel ( water supply ) in the lower area and an edge (lift barrier) in the upper area is concreted or installed as a prefabricated part in a buoyancy-proof and statically stable manner.

The hydraulic ram (floating body), which is designed like the earth trough but has a cover , is inserted into this trough.

If necessary, the system can be raised using another hydraulic ram (floating body). In this case, the cover on the first hydraulic ram is no longer required. It is then applied to the second ram.

For stiffening, the two hydraulic rams are interlocked and made of glass fiber reinforced plastic material to absorb the lateral water pressure.
