ANTI-AVALANCHE PROTECTIVE DEVICE Russian patent published in 2012 - IPC E01F7/00 

FIELD: construction.

SUBSTANCE: device actually comprises an avalanche breaker, cutting and diverting the avalanche flow from a protected object, and at least one anchor fixing the avalanche breaker with the help of a rope in a stable position on the snow cover surface, at the same time the device is made of some string material, for instance, a composite one, a metal, etc. in the form of collapsible moved structures mounted from separate elements (blocks). The avalanche breaker is made in the form of a structure triangular in plan and made of two side walls mounted on the frame and forming a cutting face with an angle, L. The avalanche-breaker is installed on the snow cover surface in the period preceding the forecasted time of avalanching. The anchor is made in the form of a multicellular structure of the shape arbitrary in plan, for instance, in the form of a rectangle, formed by vertical plates crossing at different angles and joined to each other, at the same time the anchor with the rope (ropes) is installed onto the soil before winter comes, as a result it is fixed in place with the mass of snow fallen and mass of the avalanche that came down.

EFFECT: improved protective function of a prototype through giving a device mobility, variability of shape and dimensions of its structures, and also the method to install and fix a device in an avalanche transit area.
