Construction method for forming steel trestle first and then anchoring piles
The invention relates to a construction method for forming a bridge first and then anchoring a pile of a steel trestle, and belongs to the technical field of trestle construction. The method comprises the following steps: step 1, inserting and driving a steel pipe pile of a current span trestle by a hoisting crane, and mounting an inter-pile connecting system and a pile cap; 2, a lifting crane paves a distribution beam of the current-span trestle on the pile caps, a bailey beam and a bridge deck system are installed above the distribution beam, and the transverse size of the bridge deck system is smaller than the transverse distance between the two steel pipe piles; 3, the hoisting crane carries out construction of steel pipe piles, connecting systems, pile caps, distribution beams, bailey beams and bridge deck systems of the next-span trestle, anchor piles of the current-span trestle are constructed through the punching drilling machine, and levelness data of the bridge deck systems of the current-span trestle during anchor pile construction are uploaded to a control module through a levelness sensor; an operator judges whether construction is conducted or interrupted according to the levelness data; and fourthly, the steps are repeated till construction of the multi-span trestle is completed, the construction efficiency is high, and meanwhile the influence on the trestle is small.
本发明涉及一种钢栈桥先成桥后锚桩施工方法，属于栈桥施工技术领域，步骤一：起重吊机插打当前一跨栈桥的钢管桩，并安装桩间连接系和桩帽；步骤二：起重吊机在桩帽上铺设当前一跨栈桥的分配梁，并在分配梁的上方安装贝雷梁和桥面系，桥面系的横向尺寸小于两钢管桩的横向距离；步骤三：起重吊机进行下一跨栈桥的钢管桩、连接系、桩帽、分配梁、贝雷梁和桥面系的施工，利用冲孔钻机施工当前一跨栈桥锚桩，水平度传感器将锚桩施工时当前一跨栈桥桥面系的水平度数据上传至控制模块，作业人员根据水平度数据判断施工的进行或中断；步骤四：重复上述步骤，直至完成多跨栈桥的施工，其施工效率高的同时对栈桥自身影响小。
