Construction method based on steel trestle anchor piles
The invention provides a construction method based on steel trestle anchoring piles. The method comprises the following steps: firstly, installing inner side steel pipe piles and outer side steel pipe piles, welding an inner side connecting system and outer side connecting systems, then building a cross beam and triangular steel plates, installing bailey beams and a bridge deck slab, and finally anchoring the outer side steel pipe piles. The anchoring of the outer side steel pipe piles comprises the steps of drilling anchoring holes in a rock stratum, grouting the anchoring holes and pouring concrete into the outer side steel pipe piles. According to the construction method, a drilling machine construction temporary operation platform does not need to be built, the outer side steel pipe piles in the steel trestle anchoring piles are anchored on the bridge floor in a modularized mode, a percussion drill construction temporary operation platform does not need to be built, and the construction method has the advantages of being easy to implement and operate, high in working efficiency and high in equipment utilization rate; and meanwhile, the operation of dismantling the drilling machine construction temporary operation platform is avoided, the traffic of a steel trestle is not influenced in the construction process, the construction steps are simplified, and the construction safety and the construction efficiency are greatly improved.
本发明提供了一种基于钢栈桥锚固桩的施工方法，该施工方法首先安装内侧钢管桩和外侧钢管桩和焊接内侧连接系和外侧连接系，然后搭建横梁和三角钢板和安装贝雷梁和桥面板，最后锚固外侧钢管桩；锚固外侧钢管桩包括在岩层内钻锚固孔、锚固孔注浆以及外侧钢管桩浇筑混凝土。该施工方法无需搭建钻机施工临时平台，在桥面上模块化的对钢栈桥锚固桩中的外侧钢管桩进行锚固，无需搭设冲击钻施工临时操作平台，具有易于实施和操作、工作效率高、设备利用率高的优点，同时避免了拆除钻机施工临时操作平台的操作且施工过程不影响钢栈桥的交通，简化了施工步骤，大大地提高了施工安全性和施工效率。
