COMBINED FIXING OF SLOPES Russian patent published in 2002 - IPC

FIELD: hydraulic engineering; applicable in coast-protecting structures in erodible beds of rivers, canals and other structures. SUBSTANCE: used in combined fixing of slopes are reinforced slabs. Novelty consists in that fixing is effected by foliated concrete blocks subdivided in plan by structural-functional joints into squares or rectangles interconnected with one another from all four sides by rabitsa net and formed by a layer alternating of concrete slabs joined with high-strength mortar or concrete in which rabitsa net is continuously laid or in strips in points of block joining. Said net from atop is brought onto berm and rigidly secured, and on bottom, ends of bottom fasteners are introduced into depth of slopes to form cantilevers. Numbers of layers of concrete slabs is more than two, and a number of layers of rabitsa net is more than one, and depends on values of possible static and dynamic loads. EFFECT: higher efficiency and reliability of protection of beds of rivers and canals from erosion, increased service life of coast-protecting structure. 5 cl, 12 dwg
