Large-diameter slide-resistant pile construction method in karst landform environment
The invention relates to a large-diameter slide-resistant pile construction method in the karst landform environment. Counterboring pile forming is conducted in three times through a rotary drilling rig, no mud pit or steel casing needs to be input, the construction cost is reduced, the environment pollution is reduced, disturbance to existing buildings around the construction site or nearby mountain slopes is reduced, and the construction safety coefficient is high. The perpendicularity of a drill rod is kept through a drilling machine anti-pitch cover plate, the hole-forming quality can be guaranteed, the construction progress is accelerated, and the construction period can be shortened easily.
本发明涉及一种喀斯特地貌环境下的大直径抗滑桩施工方法，采用旋挖钻机分3次扩孔成桩，无需投入泥浆池和钢护筒，节约了工程造价，减少了环境污染，减小了对施工周围已有建筑物或邻近山体边坡的扰动，施工安全系数较高；采用钻机防倾斜盖板保持钻杆垂直度，能保证成孔质量，加快施工进度，有利于缩短工期。
