Construction method for efficiently treating foundation cavity of foundation under deep covering layer
The invention provides a construction method for efficiently treating a foundation cavity of a foundation under a deep covering layer. The construction method comprises the steps of foundation cleaning, surveying and setting out, drilling machine pipe following hole forming, PVC pipe hole protection placing, drilling machine pipe following pulling out and mortar blocking, and PPR pipe inserting for grouting. The method is wide in application range, the burying depth, size and overlying soil of the cavity are not limited too much, the effect is good, the process is simple, and the manufacturing cost is low.
本发明提供了一种高效处理深厚覆盖层下地基基础空腔的施工方法，包括地基清整，测量放线，钻机跟管成孔，放置PVC管护孔，拔除钻机跟管并用砂浆封堵，插入PPR管进行注浆。该方法适用范围广，对空腔埋藏深浅、空腔大小和上覆土体没有太多限制，且效果好、工艺简单、造价低。
