Integrate structure for damage management of road-bridge transition sections in permafrost regions

An integrated structure for damage management of road-bridge transition sections in permafrost regions, comprising a plurality of slope surface cooling blocks (1), a plurality of horizontal equilibrium condensing tubes (2), and a plurality of cooling flanges (3) and targeting heat pipe arrays (7);

• wherein the plurality of slope surface cooling blocks (1) are arranged on the surfaces of the subgrade slope (4) and the abutment conical slope (5);
• the plurality of horizontal equilibrium condensing tubes (2) are installed inside the abutment-back subgrade;
• the plurality of said cooling flanges (3) are arranged on the abutment side wall;
• the targeting heat pipe arrays (7) are arranged on one side of the subgrade, consisting of a plurality of variable-angle heat pipes in evaporation sections (72), wherein the evaporation section (72) is buried below the ground surface, and the condensation section (71) of the heat pipes is directly inserted above the ground surface at a vertical angle, the plurality of heat pipes are distributed in an approximately symmetrical fan shape along the slope toe line of the abutment conical slope (5) with the center of the abutment foundation (6) as the axis;
• wherein each cooling flange (3) is vertically installed at the side wall of the abutment, and pasted or anchored by thermal conductive adhesive;
• the horizontally adjacent cooling flanges (3) are in contact with each other, and the vertically adjacent cooling flanges (3) reserve a space for heat release section;
• wherein the cooling flange comprises a shading flake (31), an insulation layer (32) and a heat pipe unit (33);
• one side of the shading flake (31) is exposed, and the other side thereof is connected with the insulation layer (32), and the insulation layer (32) is connected with the heat pipe unit (33);
• the heat pipe unit (33) is vertically adhered or anchored on the abutment side wall by a thermal conductive adhesive.
