Steel pipe pile construction method for high cantilever trestle in rapid flow deepwater bare rock area and bridge
The invention relates to the technical field of bridge construction, and provides a steel pipe pile construction method for a high cantilever trestle in a rapid flow deepwater bare rock area and a bridge. According to the steel pipe pile construction method, steel pipe pile construction is conducted in the mode that the percussion drill is wrapped by the inner-layer steel sleeve and the outer-layer steel sleeve, so that the outer-layer steel sleeve can prevent rapid flow from scouring a base and can provide relative still water construction conditions for the steel pipe pile (namely the inner-layer steel sleeve), construction can be conducted rapidly in an environment-friendly mode, slurry overflowing is effectively avoided, the structure is simple, and cost is low. Backfield processing and field installation are adopted, the reliability is high, meanwhile, equipment can be recycled for multiple times, waste and loss are reduced, and the engineering cost is greatly reduced.
本公开涉及桥梁施工技术领域，提供了一种用于急流深水裸岩区高悬臂栈桥的钢管桩施工方法及桥梁。该钢管桩施工方法通过内外双层钢套管包裹冲击钻的方式进行钢管桩施工，从而外层钢套管不仅可以防止急流冲刷基底，还可以为钢管桩(即内层钢套管)提供相对静水的施工条件，由此能够快速且环保地施工，有效避免泥浆外溢，结构简单，采用后场加工、现场安装，可靠性强，同时设备可多次循环使用，减少浪费和损耗，极大地降低了工程成本。
