Construction method of cast-in-situ bored pile in karst cave area
The invention discloses a construction method of a cast-in-situ bored pile in a karst cave area, which relates to the technical field of constructional engineering, and comprises the following steps: surveying a karst cave, drilling, cleaning a hole, connecting a steel sleeve through a positioning mechanism, hoisting the steel sleeve into the hole, inserting a waterproof plate, pouring concrete into the steel sleeve, and dismounting the positioning mechanism. By means of the method, the problem that the construction difficulty of the cast-in-situ bored pile in the karst cave area is high can be solved, and the quality of the cast-in-situ bored pile can be effectively guaranteed. The influence of a karst cave water source on cast-in-place concrete pile construction can be effectively avoided, the construction difficulty is low, and the efficiency is high.
本发明公开一种溶洞地区的钻孔灌注桩的施工方法，涉及建筑工程技术领域，包括溶洞勘察、钻孔、清孔、通过定位机构连接钢套管、将钢套管吊入孔洞、插入防水板、钢套管内浇筑混凝土、拆下定位机构，在孔洞内浇筑混凝土、混凝土初凝后拔出防水板等步骤，通过该方法可解决溶洞地区钻孔灌注桩施工难度高的问题，可有效保证钻孔灌注桩的质量。本发明可有效避免溶洞水源对混凝土灌注桩施工的影响，且施工难度低、效率高。
