Definitions

  • the invention relates to a dam element according to the preamble of claim 1, a method for its use and a dam device comprising such dam elements.
  • a protective element for use with an inventive damper Dam elements and dam devices of this type are used to contain liquids, in particular water, in the event of flooding.
  • dam element is known primarily for coastal protection, which consists of a hose section which is filled with water.
  • dam elements which are arranged in a row in such a way that successive elements abut one another on the end face, form a dam membrane which follows the coastline.
  • Dammelemen-ce of this type must be very large and heavy, otherwise they can be easily shifted or rolled away from the surrounding water masses. The requirements for the material are correspondingly high, and transportation and handling are difficult and time-consuming.
  • Another dam element is known from DE-A-41 00 889. It is designed as a double tube made of two tubes connected along a longitudinal line, which is wound on a reel, from which it can be unwound and, if necessary, with Water is filled. It is mainly used on dyke crowns on coasts and banks. Such a dam element is inevitably very heavy, even when unfilled, and transportation and handling are correspondingly difficult.
  • dam element From US-A-5 059 065 a dam element is known in which two water-filled inner hose sections are arranged side by side in an outer hose section. In the longitudinal direction successive dam elements are connected by a connecting sleeve which receives the front ends of the dam elements and the distance between them filling full elements, which are designed as water-filled sacks.
  • the dam elements are relatively complex and difficult to use. It is questionable whether the connection between the dam elements which follow one another in the longitudinal direction and which is only effective when the inner hose sections are fully filled and the full elements can withstand the action of large forces.

  • successive dam elements are through a connection tarpaulin, which under the end portions of the
  • Dam elements are pulled through and the edges of which are curled up by the same running belt pieces, are connected. This connection does not seem to be suitable for withstanding large forces. There is also no possibility of giving a dam device consisting of juxtaposed hose sections greater stability by means of cross connections between the same. Presentation of the invention
  • the invention is based on the object of specifying a generic dam element which is easy to transport and use and is nevertheless - in large numbers - suitable for building a stable dam device which can also be used to insulate a longer distance.

  • FIG. 2 shows a cross section through the dam device according to the invention along II-II in FIG. 1
  • 3 shows a section through part of the dam element according to the invention, corresponding to III-III in FIG. 2
  • FIG. 4 shows a plan view of a section of a component of the dam element according to the invention, corresponding to IV in FIG. 2,
  • FIG. 8 schematically shows a section corresponding to FIG. 7, with the filler neck in the folded state

Abstract

L'invention concerne une section flexible (1) entourée de plusieurs passants de sangle (4) qui se succèdent dans le sens longitudinal et qui sont respectivement cousus à une section de sangle sur le côté, cette section de sangle formant une sangle de raccord supérieure (8) et une sangle de raccord inférieure (9), dont les extrémités sont assemblées de façon amovible, pouvant ainsi entourer une section flexible supplémentaire (1'). Les passants successifs (4) et les sections de sangles cousues à ces passants sont reliés par une sangle longitudinale placée sur le côté. Un dispositif isolant est composé respectivement de plusieurs éléments isolants se succédant dans le sens longitudinal et d'autres sections flexible (1') qui sont parallèles aux éléments isolants, reliées à ces derniers et respectivement décalées de la moitié de leur longueur. Les éléments isolants face frontale contre face frontale sont accrochés ensemble par les sangles longitudinales et de façon identique aux autres sections flexibles (1') adjacentes par des courroies de liaison (32) tendues entre des anneaux (31) situés au niveau des sections de flexible (1, 1'). Les éléments isolants sont positionnés, remplis d'air, alignés et accrochés ensemble et aux autres sections de flexible (1') également remplies d'air. Ensuite, les sections de flexible (1, 1') sont remplies d'eau.
