Construction method for manual hole digging cast-in-place pile in karst area
The invention relates to the technical field of building construction, in particular to a manual hole digging cast-in-place pile construction method in a karst area. S1, positioning a square line; s2, building a walling crib; s3, equipment is installed in place; s4, excavating an earthwork part; s5, concrete retaining wall construction; s6, complex geological conditions of the karst area are treated; s7, arranging an expansion head at the bottom of the hole; s8, checking and accepting the foundation trench of the pile foundation; s9, pile hole cleaning; and S10, concrete pouring is conducted. According to the method, the cost is greatly reduced, the personal safety of constructors can be guaranteed, the pile foundation quality and integrity are effectively improved, and the construction efficiency is improved. The method is mainly applied to manual hole digging cast-in-place pile construction in the karst area.
本发明涉及建筑施工技术领域，更具体而言，涉及一种岩溶地区人工挖孔灌注桩施工方法。S1、定位方线；S2、砌筑的井圈；S3、设备安装就位；S4、土方部分开挖；S5、砼护壁施工；S6、岩溶地区复杂地质情况处理；S7、孔底设扩大头；S8、桩基基槽验收；S9、桩孔清理；S10、砼浇筑。本方法大大降低了成本，并能保证施工人员人身安全，有效提升桩基质量和完整性，提高了施工效率。本发明主要应用于岩溶地区人工挖孔灌注桩施工方面。
