Steel box girder bridge deck concrete pavement overlapping structure and technology thereof
The invention relates to a steel box girder bridge deck concrete pavement overlapping structure and a technology thereof.The structure comprises an upper steel box girder and a lower column type pier, the steel box girder comprises webs, a top plate and a bottom plate, vent holes are formed between the webs, and drainage holes are formed in the bottom plate in the plate length direction of the bottom plate; inner waterproof concrete, an inner waterproof bonding layer, outer waterproof concrete, an outer waterproof bonding layer and asphalt concrete are sequentially arranged on the top plate from inside to outside. The construction process is further simplified, the project amount cost of one-time cast-in-place is greatly reduced, and the fatigue resistance, stability and waterproofness of the bridge floor are remarkably improved.
本发明涉及一种钢箱梁桥面混凝土铺装叠合构造及其工艺，本发明的构造包括上部的钢箱梁和下部的柱式桥墩，所述的钢箱梁包括腹板、顶板和底板，腹板之间构成通气孔，底板上沿其板长方向开设泄水孔；所述的顶板上自内而外依次设置内防水混凝土、内防水粘结层、外防水混凝土、外防水粘结层和沥青混凝土。本发明施工工序进一步简化，一次现浇的工程量成本大大减少，桥面的抗疲劳性、稳定性和防水性都得到显著提高。
