Construction method and structure for prefabricated tubular pile to penetrate through karst cave
The invention discloses a construction method and structure for a prefabricated tubular pile to penetrate through a karst cave. Force of the prefabricated tubular pile (7) is directly transferred to aforce holding layer (2) at the bottom of the karst cave through a steel pipe (5) penetrating through the karst cave (1). The construction problems that in the process of constructing the prefabricated tubular pile in the karst cave, the prefabricated tubular pile is likely to sink and incline and the bearing capacity at the bottom of the pile does not meet design requirements are effectively solved, the effect of reinforcing a soil body of the karst cave can be effectively achieved, and the bearing capacity requirement of the bottom of the prefabricated tubular pile can be guaranteed. Meanwhile, the construction technology can be used for reinforcing the force holding layer of the pile bottom of the prefabricated tubular pile in the karst cave in a targeted manner, so that the construction period is shortened, the material loss is reduced, the construction cost is reduced, and the national green construction requirement is met.
本发明公开了一种针对预制管桩贯穿溶洞的施工方法及结构，本发明通过贯穿溶洞（1）的钢管（5）将预制管桩（7）的力直接传递至溶洞底部的持力层（2）。有效解决了在溶洞部位预制管桩施工过程中容易发生下沉、倾斜、桩底承载力达不到设计要求等施工难题，可以有效达到溶洞土体加固的效果，保证预制管桩桩底的承载力要求。同时该施工技术可有针对性的对溶洞部位预制管桩桩底的持力层加固，缩短了施工工期、节省材料损耗、降低施工成本，符合国家绿色施工要求。
