Shallow covering layer riverbed high-strength hard rock guide hole steel pipe pile and construction method
The invention relates to a shallow covering layer riverbed high-strength hard rock guide hole steel pipe pile and a construction method. The construction method comprises the following steps of integral guide frame construction, steel casing construction, impact guide hole construction, steel pipe pile construction and steel sleeve box cofferdam construction. The method has the beneficial effects that the high-strength hard rock stratum drilling construction efficiency, the steel casing positioning accuracy and construction stability and the steel pipe pile stability and safety can be improved, meanwhile, the construction quality and efficiency are improved, the construction efficiency of on-site steel casing installation, drilling and the like is greatly improved, manpower and cost are saved, and the construction period is shortened. And good technical and economic benefits can be obtained when the method is applied to practical engineering.
本发明涉及一种浅覆盖层河床高强硬岩引孔钢管桩及施工方法，包括以下步骤：施工整体式导向架、钢护筒施工、冲击引孔施工、钢管桩施工、钢套箱围堰施工。本发明的有益效果是：不但可以提高高强硬岩层钻孔施工效率、钢护筒定位准确性和施工稳定性、钢管桩稳定性和安全性，同时提高了施工质量和效率，大大提高现场钢护筒安装和钻孔等施工效率，节省人力和成本，应用于实际工程中可取得较好的技术经济效益。
