Construction method of enclosure row piles penetrating through underground cavity area
The invention relates to a construction method of an enclosure row pile penetrating through an underground cavity area, which comprises the following steps: backfilling the underground cavity area by adopting a drilling backfilling mode, the drilling range is 2m larger than the two sides of the enclosure row pile to be penetrated respectively, and the drilling depth is 2m larger than the lower part of a bottom plate of the underground cavity area; all pile positions of the enclosure row piles to be penetrated are perforated, and all pile holes are formed; before cast-in-place pile construction is carried out on each pile hole, lateral pressure prevention steel casings are arranged in backfill soil on the two sides of the corresponding pile hole correspondingly, and the lateral pressure prevention steel casings are recycled after cast-in-place pile construction is completed. According to the enclosure row pile construction method, the underground cavity is pretreated in a drilling and backfilling mode, the hole forming quality and the pile forming quality of the cast-in-place pile are guaranteed, the process is simple, and the cost is low.
本发明涉及一种穿越地下空洞区域的围护排桩施工方法，包括步骤：采用钻孔回填方式对地下空洞区域进行回填处理，钻孔范围大于待穿越围护排桩两侧各2m，钻孔深度大于所述地下空洞区域底板以下2m；于待穿越围护排桩的各桩位处进行开孔并形成各桩孔；在对每个桩孔进行灌注桩施工之前于相应桩孔两侧的回填土内分别设置防侧压钢护筒，并在灌注桩施工完毕之后回收所述防侧压钢护筒。本发明的围护排桩施工方法，通过钻孔回填方式对地下空洞进行预处理，保证了灌注桩成孔以及成桩质量，工艺简单，成本低。
