River-crossing bridge double-box-girder parallel construction method
The invention provides a river-crossing bridge double-box-girder concurrent construction method. The method comprises the following steps that S1, rails are laid on rail pads; s2, mounting a return buckle wheel and a foot pad on the lower end face of the main truss; s3, the main truss is hoisted and placed on the track, and the buckle returning wheels are fixed to the track through rear anchor rods; s4, one end of a push rod is fixed to the end of the rail, and a jack A is arranged on the end of the rail in a sleeving mode; s5, double box girders are placed on the piers; s6, after steel bars are bound in the inner formwork and the cantilever plate bottom formwork and embedded parts are installed, concrete is poured; s7, after pouring is completed, the rear anchor rod is loosened and taken out, and a jack A is started to extend to push a foot pad; s8, fixing the return buckle wheel on the track through a rear anchor rod; and S9, the steps from S1 to S8 are repeated until bridge construction is completed. The moving distance of the main truss is accurately controlled through the jack A, manual distance measurement is not needed in each moving process, the construction period is short, labor input is small, and efficiency is high.
本发明提供了一种跨江大桥双箱梁并进施工的方法，包括以下步骤：S1、在轨垫上铺设轨道；S2、在主桁架的下端面安装返扣轮和脚垫；S3、将主桁架吊起放置在轨道上，返扣轮通过后锚杆固定在轨道上；S4、在轨道的端头固定有顶推杆的一端，并套设有千斤顶A；S5、在桥墩上放置双箱梁；S6、在内模架和悬挑板底模架内钢筋绑扎和预埋件安装后浇筑混凝土；S7、浇筑完成后，松开并取出后锚杆，启动千斤顶A伸长推动脚垫；S8、再通过后锚杆将返扣轮固定在轨道上；S9、重复S1至S8步骤，直到桥梁施工完成。通过千斤顶A精确控制主桁架的移动距离，不需要每次移动都需要人工测距，工期短、劳动力投入少、效率高。
