ELEMENT DE CONSTRUCTION NORMALISE POUR TERRASSEMENTS, FONDATIONS ET TRAVAUX HYDRAULIQUES

摘要

The invention is intended to provide a construction element which can be used horizontally or vertically as drainage element in earthworks, groundworks and water engineering. It is the aim and object of the invention to manufacture a construction element which ensures efficient drainage and filtering and also damming and blocking effect. The structure of the linear textile products permits elastic or minimal permanent deformation without adverse effect on the water flow. According to the invention, compact linear textile products are strung close together in a parallel arrangement and bonded together by adhering or a yarn-bonding technique, and water-impermeable sheaths are incorporated, creating a blocking effect. The compact structure of the linear textile products ensures a mechanical damming function and the water-impermeable sheaths and the elongate capillary structure also ensure adequate directed water flow. The elimination of air circulation prevents ferric encrustation. To obtain an intensive filtering and draining function it is possible to apply in addition a water-permeable filter layer to the construction element.
