METHOD FOR BUILDING ICE CROSSING Russian patent published in 2015 - IPC E01D15/14 

FIELD: construction.

SUBSTANCE: invention can be used to build the ice crossing on natural ice. Method for building the ice crossing includes arrangement of vessels with variable buoyancy before the formation of natural ice on water basin. Each vessel is fixed at the bottom by wrapping cable with hose around the shaft fixed in the supports and filled with gas under pressure. Then, the ice covering is reinforced by disposal of the reinforcing material on its surface and subsequent freezing of ice layer on its surface. After formation of frozen layer, the vessels are lifted, and the value of buoyant force, which counteracts the load, generated by transport vehicles and moved by cargo, is determined by formula: , where: V_k - displacement of one vessel, m³; B - width of ice crossing, m; a_”к” - width of one vessel to the width of ice crossing, m; b_“к” - length of one vessel in the direction of ice crossing, m; ρ_w - water density, kg/m³; ρ_air - air density, kg/m³; h_“пл” - thickness of ice above the water surface, m; ρ_i - ice density, kg/m³; P_“к” - weight of vessel in the air, n; l - length of hoses to one vessel, m; S_“тш” - cross-section area of the hose, m²; ρ_“мк” - density of the vessel material, kg/m³; g - acceleration of gravity, m/s². During summer vessels are used as pontoon ferry.

EFFECT: improving the efficiency.
