Anti-scouring reinforced soil abutment composite bridge structure and construction method thereof
The invention discloses an anti-scouring reinforced soil bridge abutment composite bridge structure and a construction method thereof. The reinforced soil bridge abutment composite bridge structure comprises a bridge span, sheet pile wall structures symmetrically arranged along side slopes on the two sides of a river bank, a reinforced soil structure, a road and bridge transition approach and a concrete pedestal, wherein the road and bridge transition approach and the concrete pedestal are arranged on the reinforced soil structure; the sheet-pile wall structure comprises an energy-absorbing sheet-pile wall and a step sheet-pile wall which are vertically arranged on a river slope and have the same top height, the energy-absorbing sheet-pile wall, the step sheet-pile wall and a river bank slope form a cofferdam, and the reinforced soil structure is arranged in the cofferdam; and the bridge span is supported by the concrete pedestal. The cofferdams are formed on the two banks of the river channel through the steel sheet piles, a waterproof and safe construction environment is provided for construction work, the energy absorption parts are further arranged on the upstream face of the energy absorption sheet pile wall, and the problem that when the reinforced soil structure is applied to the two banks of the torrential river, inner gravel filling soil is scoured is solved.
本发明公开了一种防冲刷加筋土桥台复合桥梁结构及其施工方法，所述加筋土桥台复合桥梁结构包括桥跨、沿河岸两侧边坡对称设置的板桩墙结构、加筋土结构，以及布设于所述加筋土结构上的路桥过渡引道和混凝土台座；所述板桩墙结构包括在河道边坡竖直设置且顶部高度相同的吸能板桩墙和阶梯板桩墙，吸能板桩墙和阶梯板桩墙与河岸边坡形成围堰，所述加筋土结构布设于所述围堰中；所述桥跨由所述混凝土台座支撑。本发明利用钢板桩在河道两岸形成围堰，为施工工作提供了隔水、安全的施工环境，在吸能板桩墙的迎水面还设置吸能部件，避免加筋土结构在湍急的河流两岸应用时内部砂石填土被冲刷的问题。
