Multi-point self-balancing walking type incremental launching construction method for steel box girder
The invention relates to the field of bridge construction, and provides a steel box girder multi-point self-balancing walking type incremental launching construction method which comprises the following steps: S1, constructing pier foundations on two sides of a road; s2, temporary buttresses and pushing platforms are built on the two sides of the road; s3, a walking type pushing device is installed at the top of the pushing platform, and a bearing beam mechanism is additionally installed at the top of the pushing device; s4, guide mechanisms are installed on the pushing platforms, and the guide mechanisms arranged on the different pushing platforms are positioned in advance through positioning components; s5, hoisting the steel box girder; s6, the steel box girders are assembled to form a bridge structure, and a limiting component below the bridge structure is in sliding fit with the guide mechanism; s7, performing multi-point synchronous pushing on the bridge structure by each piece of pushing equipment; s8, side span box girder installation; and S9, dismounting the temporary buttress and the pushing platform. On the basis, the situation that the bridge structure deviates outwards in the incremental launching construction can be reduced, and incremental launching operation and accurate positioning of the bridge structure can be rapidly completed.
本申请涉及桥梁施工建设领域，提供了一种钢箱梁多点自平衡步履式顶推施工方法，包括以下步骤：S1，道路两侧施工桥墩基础；S2，道路两侧搭建临时支墩及顶推平台；S3，顶推平台顶部安装步履式顶推设备，顶推设备顶部加装垫梁机构；S4，顶推平台安装导向机构，分设于不同顶推平台的导向机构之间通过定位构件预先定位；S5，吊装钢箱梁；S6，钢箱梁拼装组成桥梁结构，桥梁结构下方的限位构件与导向机构之间滑动适配；S7，各个顶推设备对桥梁结构多点同步顶推；S8，边跨箱梁安装；S9，临时支墩及顶推平台拆卸。基于此，能够在顶推施工中减少桥梁结构向外偏移的情况，快速完成桥梁结构的顶推作业以及准确定位。
