METHOD FOR ERECTION OF AVALANCHE-BREAKERS OF BIOPOSITIVE DESIGN Russian patent published in 2011 - IPC E01F7/04 

FIELD: construction.

SUBSTANCE: in the method of avalanche-breaker erection of biopositive design, avalanche-breakers of flexible and biopositive design are arranged. Each avalanche-breaker is built in the following order - at first a reinforced concrete base is made with installation of anchors along the line of external walls, vertical stands of metal latticed frame are rigidly fixed to the anchors. Inside the frame a gabion net is mounted with attachment to lattice rods, then layers are filled with stone and soil materials, and in each layer gabion mats are made to the top of the frame. At the outer side the vertical stands of latticed frames are made of metal shaped bars or double tees, according to this technology, side walls of the avalanche breaker are erected along areas and in 4-5 sections at a time. At the same time the top of avalanche-breaker walls from the top of angle at both sides is made with inclination. And on top of avalanche-breaker walls, metal latticed structures are installed, which consist of vertical lattices, triangular cantilever protruding bars and straining rods. At the same time all these latticed structures are tightly fixed to the vertical stands and cross rods of metal frames. Avalanche-breakers are made according to the triangle shape with the angle of 80-90 degrees on top, metal latticed structures on top and along side walls of the avalanche-breaker the metal latticed structures are arranged at the distance of the frame section length from each other. Above lattices a tight metal cord is pulled through holes made in vertical stands as passing along the whole length of a triangular avalanche-breaker with free movement towards both sides, 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.

EFFECT: reliability improvement.
