Cast-in-place pile construction structure under karst cave geology and construction method
The invention mainly relates to the field of civil engineering, in particular to a cast-in-place pile construction structure under karst cave geology and a construction method. According to the construction method of the cast-in-place pile under the karst cave geology, in the construction process of the cast-in-place pile under the karst cave geology, a double-wall pile casing with high structural strength is adopted and used for maintaining the stability of a soil layer, reducing the risk of pile hole collapse and guaranteeing the engineering safety; the positioning pit is dug in the bottom face of the underground karst cave in a rotary mode through rotary digging equipment, the occupation component is placed in the positioning pit, and the occupation component has the fixed occupation performance and is used for replacing part of filler in the underground karst cave, so that the material use amount of the filler in the backfilling process can be reduced, namely in the construction process of the whole project, the construction efficiency is improved. And for each cast-in-place pile, the use amount of filler with the same volume as the occupied component is reduced. The construction cost of the cast-in-place pile can be reduced, generation of construction waste is reduced, the material utilization rate is increased, construction is convenient, and the pile foundation forming effect is good.
本发明主要涉及土建领域，具体的说是一种溶洞地质下灌注桩施工结构及施工方法。本发明公开了一种溶洞地质下灌注桩的施工方法，在溶洞地质的灌注桩施工过程中，采用结构强度较高的双壁护筒，用于维持土层的稳定性，减少桩孔坍塌的风险，保障工程的安全性；利用旋挖设备在地下溶洞底面旋挖定位坑，定位坑内放置占位构件，占位构件具有固定的占空性，用于替代地下溶洞内部分填充物，能够减少回填过程中填充物的材料用量，即整个项目的施工过程中，每一个灌注桩均减少与占位构件等体积的填充物用量。本发明能够降低灌注桩的建造成本，减少施工垃圾的产生，提高材料利用率，施工便捷，桩基成型效果好。
