Strong karst deep and large karst cavity pile foundation construction device
The invention discloses a strong karst deep and large cavity pile foundation construction device which comprises a positioning base placed on the peripheral side of a drilled hole, a circular through groove is formed in the center of the base, and the circle center of the circular through groove is aligned with the circle center of the drilled hole under the positioning effect of the positioning base; the clamping assembly is installed on the portion, on the peripheral side of the circular through groove, of the base, and the steel protection pipe placed in the circular through groove is guided and limited under the clamping effect of the clamping assembly; wherein the clamping assembly comprises an axial limiting assembly and a linkage limiting assembly, the clamping assembly is used for clamping and fixing the steel protection pipe inserted into the positioning base, so that the steel protection pipe is kept in a vertical state when being inserted into a drill hole, meanwhile, a triangular stable structure is formed between the clamping assembly and the steel protection pipe, the stability is higher, and the drilling efficiency is improved. In the downward sliding process, the circle center of the steel protection pipe and the circle center of the drill hole are always kept on the same vertical line, and therefore the possibility that the steel protection pipe deviates from the drill hole in the embedding process is reduced.
本发明公开了一种强岩溶深大溶腔桩基础施工装置，包括定位基座，放置在已钻孔的周侧，基座的中心处开设有圆形通槽，在定位基座的定位作用下以使圆形通槽的圆心与钻孔的圆心相对齐；夹持组件，安装在圆形通槽周侧的基座上，在夹持组件的夹持作用下以对放入圆形通槽中的钢护管进行导向限位；其中，夹持组件包括轴向限位组件与联动限位组件，本发明通过夹持组件对插入定位基座中的钢护管进行夹持固定，以使钢护管在插入钻孔时保持竖直的状态，同时夹持组件与钢护管之间形成一个三角形的稳定结构，稳定性更强，在下滑过程中钢护管的圆心始终与钻孔的圆心保持在同一条垂直线上，从而降低了钢护管在埋设过程中与钻孔之间发生偏移的可能。
