FIELD: construction. ^ SUBSTANCE: avalanche brake structure comprises a support frame, a suppressing screen fixed on the frame. On the support frame there is a grill made with the possibility to let a portion of a snow flow through down the slope. The suppressing screen consists of two avalanche flow scatterers - the left and the right one, connected by means of a stiffening rib, and having contours of hyperbolic concave curves in plan along with the direction of avalanche flow, and contours of parabolic concave curves in vertical plane along with avalanche flow direction. At the edges of flow scatterers and in area of their connection, to split the avalanche flow, there are support stands-scatterers installed to connect scatterer visors and the support frame. ^ EFFECT: invention increases level of objects protection against avalanche. ^ 1 cl, 3 dwg |
