METHOD TO ERECT AVALANCHE BAFFLE DAM OF BIOPOSITIVE DESIGN Russian patent published in 2011 - IPC E01F7/04 

FIELD: construction.

SUBSTANCE: in the method to erect an avalanche baffle dam of biopositive design, flexible latticed structures are installed at the distance from each other at the crest, which are made of metal sections of various types to form rectangular cells. At the same time vertical stands of lattices and their counterfort beams are tightly attached to anchors, installed in a reinforced concrete fixture of an upper slope and the crest. And above the metal lattices a tight metal rope is pulled through holes made in vertical stands with free travel to both sides. Then the rope in two points in the beginning of the dam and at the top of the rotation angle at both left and right sides of the dam is fixed to anchors with adjustment tightening devices installed opposite to the discharge side of the dam. Each side of the dam has its separate system of rope tensioning. The dam route in plan is made with an angle of rotation opposite to the dominant direction of the avalanche, the crest from the top of the angle of rotation to both sides is arranged with a slope. At the lower slope of the dam, fertile vegetable soil is laid in parallel strips and with sodding into a dam body, where trees and bushes are planted in rows with a developed root system.

EFFECT: method to erect the avalanche baffle dam of biopositive design is intended for engineering and nature conservation protection against avalanching at mountain areas of tourist and recreation areas.
