Abstract

A polymer sheet is laid on the river bed so as to even the bed out, one sheet with and one without inbuilt stiffeners and push-rods to unroll the sheet. The sheet is anchored to the river bed and can be installed in the autumn still rolled up so that the sheet rolls out in the thaw with the accelerated water flow, even without the use of pumps.

Description

In Ergänzung zur Patentanmeldung, in der ein Verfahren zum Hochwasserschutz an Flüssen beschrieben wird, das durch eine künstliche Erhöhung der Fließgeschwindigkeit der Wassermenge direkt im Flußlauf hin zum Meer oder seiner Zuflüsse in den Hauptfluß durch abpumpen mittels eines Pumpwerks realisierbar ist, wird zur Steigerung der Effektivität eine zusätzliche Vorrichtung vorgeschlagen.In addition to the patent application, in which a procedure for flood protection Rivers is described by an artificial increase in the flow rate the amount of water directly in the course of the river towards the sea or its inflows into the main river by pumping out by means of a pumping station, will increase the Effectiveness proposed an additional device.

Zur Verringerung der Bremswirkung des Wasserlaufes auf einzelnen Flußabschnitten, zum Beispiel am Beginn einer kleineren Sohlengefälle oder in den Abschnitten mit hoher Rauheit auf der Sohle des Flusses zur Ausgleichen der Bodenunebenheiten, wird im Flußbett ein Blatt aus polymerem Werkstoff in Flußrichtung ausgelegt. Es sind 2 Blattformen vorgesehen, die eine ohne (Fig. 1) - und die andere mit eingebrachten inneren Elementen (Fig. 3). Ist eine Pumpstation vorhanden, wird diese Vorrichtung ober- beziehungsweise unterhalb dieser ausgebracht.To reduce the braking effect of the watercourse on individual river sections, for example at the beginning of a smaller bed slope or in the sections with high roughness on the river bed to compensate for the unevenness in the river bed, a sheet of polymeric material is laid out in the flow direction. Two leaf shapes are provided, one without ( Fig. 1) - and the other with inserted internal elements ( Fig. 3). If a pumping station is present, this device is deployed above or below it.

Das Blatt aus polymerem Werkstoff entfaltet sich beim Einbringen in den Fluß und wird mehrfach auf dem Boden verankert (Fig. 2).The sheet of polymeric material unfolds when it is introduced into the river and is anchored several times to the bottom ( Fig. 2).

Zur Verhinderung von Überschwemmungen im Frühjahr kann das Blatt bereits im Herbst zum Überwintern unausgerollt in den Fluß eingebracht werden (Fig. 4).In order to prevent flooding in spring, the leaf can be rolled into the river unrolled in the winter for the winter ( Fig. 4).

Die im Wasser befindliche Rolle wird während der Tauperiode im Frühjahr aktiviert. Dies erfolgt mittels Einpumpen von Wasser in, auf das Blatt angebrachte Versteifungsrippen und Stößel zur Entfaltung des gesamten Blattes (Fig. 5).The role in the water is activated during the thawing period in spring. This is done by pumping water into the stiffening ribs and plunger attached to the sheet to unfold the entire sheet ( Fig. 5).

Das Blatt ist zur mehrfachen Benutzung ausgelegt, wofür sie jeweils nach Verwendung aus dem Wasser geholt und wieder eingerollt wird.The sheet is designed for multiple uses, for which they each after use is taken out of the water and rolled up again.

Die Vorrichtung zur beschleunigten Wasserabfluß kann, zum Beispiel, an kleinen Flüssen ohne Pumpstation eingesetzt werden.The device for accelerated water drainage can, for example, on small rivers can be used without a pumping station.

Claims

1. A device as a supplement to the method for flood protection on rivers, which by an artificial increase in the flow rate of the amount of water directly in the river towards the sea or its inflows into the main river by pumping by means of a pumping station, characterized in that it is a sheet of polymeric material , which is laid out on the bottom of the river to compensate for uneven ground.

2. The device according to item 1 , characterized in that it is a sheet of polymeric material. in 2 forms, without - and with inserted internal elements, which are stiffening ribs and plungers for unfolding the entire sheet.

3. The device according to item 1 , characterized in that it unfolds when introduced into the river, or the role in the water is activated, in which by means of pumping water into, attached to the sheet of polymeric material stiffening ribs and plunger, the serve to unfold the entire sheet, in both cases the sheet is anchored to the ground.

4. The device according to item 1 , characterized in that the leaf can already be rolled into the river unrolled for the winter for the winter.

5. The device according to item 1 , characterized in that it can be used, for example, on small rivers for accelerated water drainage even without a pumping station.
