DEVICE FOR PROTECTION OF SLOPES AND ROAD BASE Russian patent published in 2000 - IPC

FIELD: construction, in particular, devices for protection of road slopes, bank slopes and pond beds, slopes of open pits of mining industry, as well as for construction of road base, water-development works, applicable for prevention of erosion of pond underwater bank slope. SUBSTANCE: the device has a pile of flexible polymeric strips arranged in several raws and interconnected in chess-board order in the length of the strips for formation of a cellular construction at extension of the strips in the direction normal to the surface of the strips. The novelty is in the fact that the strips are joined by hot-pressure welding; the relation between thickness d of the polymeric strip and its width b makes up 0.004 to 0.02, and the relation between thickness d of the polymeric strip and width a of joint weld of these strips - 0.05 to 1.0. EFFECT: enhanced stiffness of cell and strength of joint welds of the strips, provision of uniform distribution of loads on construction members of each cell and redistribution of these loads on construction members of the adjacent cells. 12 cl, 8 dwg, 1 ex
