Steel box girder installation construction structure and using method thereof

LIN JIMING

The invention belongs to the technical field of bridge construction, and particularly relates to a use method of steel box girder installation construction, which comprises the following steps: steel box girder storage construction: S1, swinging and moving a side span girder section to a girder transporting flatcar through a hydraulic synchronous lifting system installed at a mid-span side, transporting the girder section through a girder transporting rail to pass through the inner sides of the roots of two tower columns, and transporting the girder section to the middle span side; storing the beam at a hoisting position; s2, the hydraulic synchronous lifting systems installed on the side span side are swung to a beam storage support for secondary lifting and beam falling and then longitudinally moved in place, and four sets of hydraulic synchronous lifting systems are put in total; and S3, erecting a beam storage support between the tower anchors, filling a site, installing a hydraulic synchronous lifting system, constructing the beam storage support between the tower anchors and the site, and laying a beam storage track. The steel box girder can be installed step by step and section by section according to actual conditions, the installation quality and efficiency are guaranteed, and good operation can be conducted in a small-space working range.

本发明属于桥梁施工技术领域，尤其是涉及一种钢箱梁安装施工的使用方法，包括如下步骤：钢箱梁存梁施工：S1.通过中跨侧安装的液压同步提升系统荡移边跨梁段至运梁平车上，通过运梁轨道运输梁段经两塔柱根部内侧穿过，存梁于吊装位置；S2.利用边跨侧安装的液压同步提升系统荡移至存梁支架上二次提升落梁再纵移就位，共投入4套液压同步提升系统；S3.搭设塔锚间存梁支架、填筑场地及安装液压同步提升系统、施工塔锚间存梁支架及场地，铺设存梁轨道。本发明能够根据实际情况对钢箱梁进行分步分段安装，保证了安装质量和效率，在小空间的工作范围也能够进行很好的操作。
