FIELD: construction. ^ SUBSTANCE: antiavalanche structure made in the form of a springboard-tray on vertical bearing supports, the springboard is made with periodical profile with a convexo-convex surface separated in the middle with a rigid rib into two symmetrical halves, and in the end part the springboard along the entire length is smoothly turned upwards, where at a certain distance from each other longitudinal baffles are arranged with an expansion angle of 15-30 from the line of the rib rigidity and having a reverse inclination on top. A curvilinear site of the springboard is made of metal boards coated with a polymer composite material on top, and round contour is given to the end part of the springboard in plan. ^ EFFECT: method to erect an antiavalanche structure of combined design may be efficiently used on areas of territories of mountain and tourist infrastructures located in most dangerous zones of impact exposure to heavy avalanches of 3 and 4 size. ^ 2 cl, 3 dwg |
