Construction equipment and construction method for pile foundation karst cave under karst geology
The invention relates to the technical field of pile foundation karst cave treatment under the karst geology, in particular to pile foundation karst cave construction equipment and method used under the karst geology, and the pile foundation karst cave construction equipment comprises a pile casing, an overhead lifting motor, a sonar detection probe connected with a monitoring unit through a communication cable, an adjusting motor and an external conveying pipe used for conveying backfill powder. According to the pile foundation karst cave construction equipment used under the karst geology and the construction method, the slurry condition of a cast-in-situ bored pile is fully utilized, the development condition of a karst cave within 10 m of the pile bottom can be tracked and detected in the hole forming process, and the pile foundation karst cave construction equipment and the construction method have the advantages of being low in cost, high in speed, high in precision and the like; by adopting a lifting follow-up operation mode, sonar detection and treatment can be carried out on the inner wall of the whole drill hole, the pile bottom can be treated, the hole wall can be operated, and the detection range and the treatment range are wider.
本发明涉及岩溶地质下的桩基溶洞处理技术领域，尤其是一种用于岩溶地质下的桩基溶洞施工设备以及施工方法，包括护筒、顶置升降电机、与监测单元通过通信电缆相连接的声呐探测探头、调节电机和用于输送回填粉料的外部输送管。本发明的一种用于岩溶地质下的桩基溶洞施工设备以及施工方法通过充分利用了钻孔灌注桩的泥浆条件，可以在成孔过程中跟踪探测桩底10m内溶洞发育情况，具有成本低、速度快、精度高等优点；通过采用升降随动操作方式，可以对整个钻孔内壁进行声呐探测和处理，不仅可以处理桩底，还可以对孔壁进行操作，探测范围和处理范围更加广泛。
