Construction method of multi-box-chamber steel box girder
The invention discloses a construction method of a multi-box-chamber steel box girder. The construction method comprises the following construction steps that S1, an assembling platform used for assembling the steel box girder is erected at a preset position; s2, splicing a preset number of steel box girders, and welding the steel box girders to form a steel box girder assembly in a preset shape; s3, transporting the steel box girder assembly body in the preset shape to a girder erection area by adopting transportation equipment; s4, a beam feeding step is carried out on the steel box beam assembly body; s5, erecting the steel box girder assembly to a designed position by using a bridge girder erection machine; s6, the steps S2 to S5 are repeated, and erection of all the steel box girder assemblies is completed; s7, an operation platform used for assisting the bridge girder erection machine in installing the steel box girder is installed; s8, transverse partition plates between box chambers in the steel box girder assembly bodies are connected through high-strength bolts by means of the operation platform; s9, transverse seams of the adjacent steel box girder assembly bodies are connected in a welded mode through an operation platform; s10, beam bottom operation is conducted through the operation platform; and S11, after the inspection and acceptance are qualified, the operation platform used for assisting the bridge girder erection machine to install the steel box girder is dismantled.
本发明公开了一种多箱室钢箱梁的施工方法，包括以下施工步骤：S1.在预设位置搭设用于拼装钢箱梁的拼装平台；S2.拼装预设数量的钢箱梁使其焊接形成预设形状的钢箱梁装配体；S3.采用运输设备将形成预设形状的钢箱梁装配体运输至架梁区；S4.对钢箱梁装配体进行喂梁步骤；S5.利用架桥机将钢箱梁装配体架设到设计位置；S6.重复步骤S2～S5，完成所有钢箱梁装配体的架设；S7.安装用于辅助架桥机安装钢箱梁的操作平台；S8.利用操作平台对各个钢箱梁装配体中各个箱室之间的横隔板采用高强螺栓进行连接；S9.利用操作平台将相邻钢箱梁装配体的横缝焊接连接；S10.利用操作平台进行梁底作业；S11.检查验收合格后，拆除用于辅助架桥机安装钢箱梁的操作平台。
