1. , a kind of method that reduces disadvantageous temperature effect on main girder structure of bridge one of is characterized in that at least in the following manner realizing:

  • (1) in the waterproof concrete layer on surface, adds the thermal insulation material, have the thermal insulation waterproof concrete layer of mating formation so that form at bridge main beam structure end face;

    (2) insulating layer that one deck is made up of pressure-resistant material of between bridge main beam structure and waterproofing course, mating formation, so as to reduce or the heat of blocking surperficial concrete pavement layer to the transmission of bridge main beam inside configuration;

    (3) in the waterproofing course between bridge main beam structure and concrete pavement layer, add the thermal insulation material, so that the water-proof thermal-insulation layer that one of formation can reduce or intercept heat is transmitted between bridge main beam structure and concrete pavement layer;

    (4) in the waterproof concrete leveling layer between asphalt concrete pavement layer and bridge main structure, add the thermal insulation material and form thermal insulation waterproof concrete leveling layer, the interchange of heat between blocking-up and minimizing asphalt concrete pavement layer and the bridge main beam structure;

    (5) between waterproofing course and concrete leveling layer, increase shop one deck insulating layer, reduce or block heat transmission between surperficial asphalt concrete pavement layer and the concrete leveling layer;

    (6) in waterproofing course, add the thermal insulation material, form the water-proof thermal-insulation layer, to reduce or to block heat transmission between surperficial asphalt concrete pavement layer and the concrete leveling layer;

    (7) in the asphalt concrete pavement layer on surface, add the thermal insulation material, form the thermal insulation asphalt concrete pavement layer, to reduce or to block heat transmission between surperficial asphalt concrete pavement layer and the waterproofing course.
