Soft soil foundation deep foundation pit water interception excavation supporting device and supporting method
The invention belongs to the technical field of foundation pit construction, and particularly relates to a supporting device and method for water interception excavation of a deep foundation pit of a soft soil foundation. A drill rod is in threaded connection with a drill arm of the anchoring drilling machine; the end, away from the anchoring drilling machine, of the drill rod is in threaded connection with a spiral bit. An annular groove forming structure is arranged between the drill rod and the spiral drill bit; the annular groove forming structure comprises a fixed seat; the two ends of the fixing base are in threaded connection with the drill rod and the spiral drill bit correspondingly. A plurality of mounting grooves are uniformly formed in the middle of the periphery of the fixed seat; an annular groove pressing block is slidably mounted in the mounting groove; a driving unit is arranged between the annular groove pressing block and the mounting groove; the multiple annular grooves are evenly formed in the inner wall of the anchor hole, so that after concrete is injected to form the anchor pile, the multiple convex rings matched with the annular grooves are arranged on the outer ring of the anchor pile, the connection strength between the anchor pile and the anchor hole is improved, and then the supporting effect on the side slope is improved.
本发明属于基坑施工技术领域，具体的说是一种软土地基深基坑截水开挖支护装置及支护方法，包括锚固钻机；所述锚固钻机的钻臂上螺纹连接有钻杆；所述钻杆远离锚固钻机的一端螺纹连接有螺旋钻头；所述钻杆与螺旋钻头之间设置有环槽开设结构；所述环槽开设结构包括固定座；所述固定座的两端分别与钻杆和螺旋钻头螺纹连接；所述固定座的外周中部均匀开设有多个安装槽；所述安装槽的内部滑动安装有环槽压块；所述环槽压块与安装槽之间设置有驱动单元；通过在锚孔的内壁上均匀开设多个环槽，使得注入混凝土形成锚桩后，锚桩的外圈具有多个与环槽相匹配的凸环，从而锚桩与锚孔之间的连接强度，继而提高了对边坡的支护效果。
