Anchoring assembly, anchoring structure and construction method of anchoring structure

CHEN TAILIN

The invention discloses an anchoring assembly, an anchoring structure and a construction method of the anchoring structure. The technical problem that grouting and rod body imbedding cannot be achieved due to the fact that soil nails and anchor rod holes are difficult to form in a soft soil layer is solved. One end of the rod body is provided with a crosshead, and the drill rod is correspondingly arranged outside the rod body in a sleeving mode. A groove matched with the crosshead is correspondingly formed in the corresponding end side of the drill rod; a corresponding fit clearance is reserved between the drill rod and the rod body during assembly; the rod body is a soil nail steel bar rod body or an anchor rod steel bar rod body. The drill rod and the rod body are designed to be of a structure easy to combine and separate, so that the three working procedures of drilling, grouting and rod body imbedding are carried out at the same time, the construction and material cost is greatly reduced, the operation is simple, the working efficiency is high, the soil taking effect can be avoided, and the construction safety is improved.

本申请公开了一种锚固组件、锚固结构及锚固结构的施作方法，旨在解决在软弱土层中土钉及锚杆成孔难而导致无法注浆及置入杆体的技术问题。其主要包括一端带有十字头的杆体、用于对应套设于该杆体外的钻杆；所述钻杆对应端侧对应设有与所述十字头相匹配的凹槽；装配时所述钻杆与所述杆体间留设对应的配合间隙；所述杆体为土钉钢筋杆体或锚杆钢筋杆体。本申请通过将钻杆与杆体设计为易结合、分离的结构，以实现钻孔、注浆及杆体置入三道工序同时进行，大大降低了施工及物料成本，其操作简单，作业效率高，且可避免产生取土效应，提高了施工安全性。
