DE19754340A1 - Protection against high water flooding - Google Patents

Abstract

The collection of fabric hoses (1) acts as a flood barrier. Filling and emptying devices are typically installed on the face sides. The device is filled with flood or well water. An arbitrary formation of the system can be laid out and taken into service and correspondingly filled to the correct level. The operating excess pressure imparts the static stability to the system. The device can be installed at the application location or elsewhere when in the emptied state. It can be encased when installed in areas at risk from flotsam and jetsam. The device can be used for closing broken portions of dykes, in that it can be introduced as an individual component or in combination into the break point, and after anchoring with the filling seals the break.

Description

The invention relates to a device for protecting buildings, farmsteads, cities or Areas before floods, consisting of at least one tubular waterproof textile Tubes of any length and constructionally variable diameter, which is closed on the end faces and typically has filling or emptying valves on the end faces, possibly several Tubes combined as a system combined in a constructive manner and with flood or groundwater Overpressure to be filled for static stability.

As a basic concept, flood protection has hitherto been endangered on rivers or similar Areas with increasing flood levels either constantly increasing dike ridges or as temporary Measures sheet piling and sandbag barriers enforced.

Such measures are often disadvantageous because in built-up areas, towns and cities do a lot of that The peculiarity of the traditional, often touristically effective bank architecture is lost. In Island locations, e.g. B. Courtyards in renaturation areas, can rarely be temporary when there is an acute risk of flooding Measures to protect against flooding are used because material and personnel are compatible with the previous ones Methods cannot be used in a diversified manner due to bottlenecks, but rather to the Main focal points (dykes) are used.

For economic reasons, it is also often forbidden for long periods occurring abnormal water levels also smaller residential units or farmsteads in polder areas etc. to be provided with permanent flood walls or dikes.

Furthermore, in the event of unpredictable dike breaks, the hinterland can be flooded in a few hours will. However, all previous protective measures can only be produced with great expenditure of time that for this reason alone effective protection could not be established. this leads to especially in agricultural areas for equipping and evacuating animals vulnerable areas. This leads to a clear one in the herds as well as receiving increased risk of illness, u. U. to epidemic spreading diseases.

Furthermore, looting or destruction must be expected in evacuated companies and buildings will.

This invention is now based on the object to provide temporary flood protection, depending according to scope, installed by one or more people in a few hours and / or ready for operation can be made. In addition, due to the constructive peculiarity of the flood protection system in island locations, the hose system can be stored in a relatively space-saving manner so that it can be used immediately if necessary to be available without the use of external forces (military, civil protection, etc.) have to.

Another object of the invention is to make the temporary flood protection self-sufficient, e.g. B. as a farmer or Small community to be able to use, since it is unlikely in crises, first of all over functioning Transport and logistics routes are available; secondly, there are potential assistants at other focal points tied and third are in flood crises u. U. the usual communication channels (telephone) failed.

With the presented invention, further river restoration areas can now be identified, those due to the flooding hazards of the buildings there and their flood protection Up to now, economically inconsistent expenses were impossible, not in previous planning could be included. With the  newly developed flood protection system is an inexpensive and effective solution Agreement on conservation and economic issues available.

In the end, this new flood protection device enables extremely low device and in particular also cost a similar flood protection, as stationary buildings in the general offer.

To ensure independence from any external infrastructure (energy, external personnel, Transport capacities), it makes sense to fill the system with water to provide internal combustion engine-driven pumps, if necessary with power-operated units Keep generators ready to produce the stabilizing operating pressure even in the event of leaks.

The filling can be automated in polder areas and river courses with the corresponding relief energy, the Gravity principle following (Mühlenbach principle) happen. For this, in the upper reaches or on determining dike levels to install inlets and with the pipe system of the temporary Flood protection system to connect. When the tide rises, the system is filled and with it ready for use.

With a slightly changed design, the system elements can be used as a means of repairing Dike breaks can be used. To do this, the elements that have not yet been filled are left in the dike gap float. Once there, they are anchored in the water, river or canal bed and typically filled on the sea side. With their own weight and volume, they are able to close dike gaps or to prevent further dike erosion. Possibly. are several system elements for the complete closure of Breakthroughs required.

The present invention will be explained in more detail below using exemplary embodiments. In the show the corresponding drawing,

Fig. 1 m a cross-section through the inventive device in a flood protection height of approximately 3,

Fig. 2 shows a circular configuration for system protection to a farm in Auenlage with a flood protection height of about 1.20 m,

Fig. 3 is a schematic representation of the basic structure of the device.

It is possible to use a variety of variants of the flood protection device described here to modify. So it is not mandatory, from how many tubes that are connected System must exist. It becomes in the sense of an optimization of protection concerns and justifiable Costs can be tailored individually. The length of a pipe is constructively arbitrary however for transport reasons at approx. 800 m max. lie. The system components are prepared by Eyelets connectable on the end faces. Flood water resistance is ensured by a min. 0.5 mm strong, 15 m overlapping film ensures that the seam surrounds.

Claims (4)
