AVALANCHE-BREAKER OF BIOPOSITIVE DESIGN Russian patent published in 2011 - IPC E01F7/04 

FIELD: construction.

SUBSTANCE: avalanche-breaker made of descending walls, which form a sharp angle on the top, is arranged with flexible and biopositive design, avalanche-breaker walls are made of gabion and soil mats laid in reinforcement latticed frames of prefabricated design. Vertical stands of latticed frames are made of metal shaped bars or double-tees anchored in a reinforced concrete base arranged along the whole length of head walls. Above the avalanche-breaker walls there are metal latticed structures made of vertical grids, triangular cantilever protruding bars and straining rods, at the same time all these latticed structures are rigidly fixed to the vertical stands and transversal rods of metal frames. The avalanche-breaker has a triangle shape with the angle of 80-90 degrees, on top along side walls of the avalanche-breaker the metal latticed structures are arranged at the distance of the frame section length from each other, and at the same time both ends of the cord are fixed to anchors with adjustable tightening devices arranged in front of the avalanche-breaker top. Some mats arranged inside the metal frame closer to external walls and on top of the avalanche-breaker are made of geogrid and a fertile vegetable soil with addition of seeds of permanent grasses and bushes, and the inner part between side walls of the triangular avalanche-breaker are filled with local and vegetable soil with planting of trees and bushes. The proposed design of the avalanche-breaker provides for suppression of excessive energy of avalanche flow and impact force dispersal over a larger area, thus reliability of structures operation increases.

EFFECT: avalanche-breakers of biopositive design may be efficiently used at areas of mountain infrastructure territories located in most endangered zones of powerful avalanches impact action.
