Method to collapse snow eaves on avalanche-prone slopes According to the method, before collapse of snow eaves on avalanche-prone slopes by means of cutting of their cantilever part, according to preliminary results of observations carried out in winter period, eave-dangerous sections are detected on a ridge. In summer period on the ridge of every eave-dangerous section, near the ridge line on the windward area of the slope, a permanent scaling benchmark is installed, with the help of which then after every snowstorm the length of the cantilever part of the snow eave is measured. When the size of this part of the snow eave achieves the permissible limit value for this part of the ridge, the action is taken against the snow eave, and it is collapsed. When detecting length of the cantilever part of the snow eave, digital video filming or photomapping of the scaling benchmark is carried out on the background of the snow eave, and by ratio of their dimensions the sought for size of the cantilever part of the snow eave is determined. The permanent scaling benchmark is made in the form of a stand solidly mounted into rock soil on the top of the range, and a cantilever size ruler fixed to the stand, equipped with an appropriate measurement scale and directed towards the windward area of the slope. The stand to the level of the cantilever size ruler is also equipped with an appropriate scale for measurement of snow height directly on the range ridge. |

Then after each snowstorm, having attached themselves through a safety belt to safety anchors, they inspect and measure length of snow eave cantilever with the help of a weight and a reepschnur, for this purpose the weight fixed to the end of the rope is thrown over the edge of the eave, and then pulled to the edge of the eave. Afterwards a point of expected crossing with the ridge line is marked on the reepschnur, and the length of rope is measured in the section between this mark and the weight, then, comparing thus measured length of cantilever part of the snow eave with its permissible limit value for this slope, they forecast the start of spontaneous collapse of snow eave. Installation of landmarks and safety anchors on the ridge primarily takes place in summer period. |

Proposed unit comprises frame coupled via axle with rotary guard element made up of hollow beam jointed with its drive balanced by at least one counterweight. Transverse reinforcing webs are arranged inside said hollow beams. Thrusts are arranged under said webs while axle ends are fitted in bearing supports coupled with aforesaid frame. Metal grid making the foundation carcass in mounting proposed unit on the road is arranged along the frame edges and under it. |

Avalanche-protective dam of combined design In an avalanche-protective dam of combined design on a crest there are flexible latticed structures made of metal profiles of various types, bars and others, rigidly connected to each other mutually perpendicularly to form rectangular cells, vertical stands and their buttress beams are strongly fixed to anchors installed in a reinforced concrete fixture of an upper slope and a dam crest. The dam track in plan passes with a turn angle opposite to the dominant direction of the avalanche, and the dam crest from the top of the turn angle to both sides has an incline of 0.01-0.05. Along the dam crest the metal latticed structures are arranged at the distance from each other, along the top of the lattices via holes made in the vertical stands there is a metal rope pulled with free travel to both sides. The rope is fixed to anchors with controlled tensioning devices arranged opposite to a discharge side of the dam. The proposed design of the dam provides for suppression of excessive energy of avalanche flow and distribution of impact force at higher area, therefore facilities operation reliability increases. |

Front damping automotive guard and damping cartridge for it Invention relates to automotive passive protection means. Proposed guard comprise frame with attachments to vehicle or stationary structure, and damping cartridge jointed to said frame. Damping cartridge comprises case with means to absorb energy generated in collision. Damping cartridge rear section serves to interact with vehicle driven into guard. Its central section serves to decelerate and absorb kinetic energy due to deformation and destruction of energy absorbing means. Its front section serves to limit cartridge deformation and to be attached to base component of road front guard. Cartridge central part energy absorbing means are formed by vertical shaped sheet elements with beads oriented in crosswise direction relative to cartridge lengthwise axis and in opposite direction relative to adjacent elements. Beads of shaped sheet elements are formed by walls and vertical flanges. Adjacent shaped sheet elements are jointed together along vertical flanges either directly or via flat sheet elements to form cells between inclined walls and flanges of adjacent shaped sheet elements. Cartridge front section located on the side of base component of road front guard represents a frame with stiff traverse element. Cartridge rear section represents a 3d module made from thin-sheet material with trapezoidal cross section filler with porous filler. 3d-module vertical flange is jointed with vertical flanges of adjacent shaped sheet element of cartridge central section. |
