Recyclable foundation pit supporting anchor rod and construction method thereof
The invention discloses a recoverable foundation pit supporting anchor rod and a construction method thereof. The recoverable foundation pit supporting anchor rod comprises a drill bit, a hollow drill rod, a plastic sleeve and an anchor rod body. An annular protruding part and a connecting hole are arranged at the tail end of the drill bit, a plurality of connecting grooves are formed in the inner circumferential wall of the connecting hole, each connecting groove is provided with a clamping groove part, a straight groove part and a guide groove part, the tail end of each straight groove part extends to the tail end of the connecting hole, and the two ends of each guide groove part are connected to the head end of the corresponding clamping groove part and the head end of the corresponding straight groove part respectively. The head end of the hollow drill rod is sleeved outside the annular convex part in a threaded manner; the plastic sleeve is arranged in the hollow drill rod, and the head end of the plastic sleeve is inserted and fixed in the annular protruding part; the anchor rod is arranged in the plastic sleeve, a connector is arranged at the head end of the anchor rod, a plurality of convex columns clamped in the clamping groove parts one by one are arranged outside the connector, and a spring supported at the head end of the connector is arranged in the connecting hole. Drilling and mounting of the anchor rod can be synchronously carried out, the construction efficiency is improved, the structure is simpler, and the cost is lower.
本发明公开了一种可回收基坑支护锚杆及其施工方法，该可回收基坑支护锚杆包括钻头、空心钻杆、塑料套管和锚杆；钻头的尾端设有环状凸出部和连接孔，连接孔的内周壁设有多个连接槽，各连接槽均具有卡槽部、直槽部和导槽部，直槽部的尾端延伸至连接孔的尾端，导槽部的两端分别连接于卡槽部和直槽部的头端；空心钻杆的头端螺纹套接于环状凸出部外；塑料套管置于空心钻杆内，塑料套管的头端插接固定于环状凸出部内；锚杆置于塑料套管内，锚杆的头端设有一连接头，连接头外设有多个一一卡接于各卡槽部内的凸柱，连接孔内设有支撑在连接头头端的弹簧。本发明不仅能够同步进行锚杆的钻孔和安装，提高了施工效率，而且结构更简单，成本更低。
