Flexible layer structure for protecting earthworks, bed walls and for

Abstract

The invention relates to a layer construction formed as a net for the protection of earthworks, constant or periodical water courses, steep area surfaces, for building dams and embankments, for the laterial delimitation of materials tending to spreading, as e.g. sludges, soaked embedding materials. The net to be built-in into the protective layer or earthwork is fixed to the substructure of compacted soil by means of proper fixing elements. After having filled the meshes of the net with a filler, the confining walls of the meshes are carrying the load and stresses acting on the surface. The structure according to the invention follows the motion, consolidation of the earthwork and the substructure flexibly, without getting damaged. The side-walls made of a geotextile are staying in the path of water flow streaming on the surface or next thereto, thus reducing velocity and energy of streaming sickering water; soaked embedding materials of dams and dikes are kept together, neither earthworks nor field surfaces become damaged, materials with a high water content cannot be spread, sludge and soaked ballast bed are protected. By using the structure according to the invention, by using natural materials, as earth, gravel, rocks, sludge, stable crusts and layers can be formed in earthworks, dams, dikes and embeddings well resisting to soil-mechanical stresses and surfacial effects.
