Support-free active closing construction method for large-span steel box girder
The invention relates to the technical field of installation and construction of steel box girders, and provides a non-support active closure construction method for a large-span steel box girder, which comprises the following steps: S1, constructing the top of a pier to the design elevation of a low pier structure; s2, a falling support is constructed at the position of a low pier structure of the pier; s3, an adjusting mechanism is installed at the low pier structure of the pier; and S4, hoisting equipment is installed at the end of the steel-concrete combined section. S5, the bottom side of one end of the steel box girder abuts against the temporary support through a floating crane, and the other end of the steel box girder is hoisted through hoisting equipment; s6, the floating crane and the steel box girder are disconnected; s7, adjusting the position of the steel box girder; s8, dismantling the temporary support; s9, the steel box girder is lowered through cooperation of the jacking jack and the hoisting equipment until the bottom of the steel box girder abuts against the falling support; s10, welding and fixing the closure end of the steel box girder and the end part of the steel-concrete combined section; and S11, a high pier structure of the pier is constructed. The method has the effect of facilitating installation and construction of the steel box girder.
本申请涉及钢箱梁安装施工的技术领域，提出了一种大跨径钢箱梁的无支架主动合拢施工方法，包括以下步骤：S1：桥墩顶部施工至低墩结构设计标高；S2：在桥墩的低墩结构处施工落位支座；S3：在桥墩的低墩结构处安装调节机构，S4：在钢混结合段端部安装吊装设备。S5：通过浮吊使钢箱梁一端底侧与临时支座抵接，将钢箱梁的另一端通过吊接设备吊起；S6：断开浮吊与钢箱梁的连接；S7：钢箱梁位置调节；S8：拆除临时支座；S9：通过顶升千斤顶配合吊装设备下放钢箱梁，直至钢箱梁底部抵接于落位支座；S10：将钢箱梁合拢端与钢混结合段端部进行焊接固定；S11：施作桥墩的高墩结构。本申请具有便于钢箱梁安装施工的效果。
