Novel construction method for jet grouting expansion anchor rod or anchor cable
According to the construction method of the novel rotary jet grouting expansion body anchor rod or anchor cable, the preset first rotary jet grouting expansion body is used for forming a limiting table capable of abutting against the first rotary jet grouting expansion body, so that the continuously-placed anchor cable part is forced to be gradually wound and arranged in the second rotary jet grouting expansion body, and after the second rotary jet grouting expansion body is solidified, the anchor rod or anchor cable is fixed to the first rotary jet grouting expansion body. The binding force between the anchor cable part and the second jet grouting expanding body is stronger, and the anchor cable part is not easy to separate; when the rotary jet grouting expansion body and the second rotary jet grouting expansion body are arranged in a non-spaced mode, namely, the second rotary jet grouting expansion body abuts against each other, the second rotary jet grouting expansion body abuts against the bottom face of the rotary jet grouting expansion body, and the anchoring force of the anchoring part is further increased.
本发明提供了一种新型旋喷扩体锚杆或锚索的施工方法，本发明利用预先设置的第一旋喷扩大体形成一个可以抵靠的限制台，从而迫使持续置入的锚索部逐渐盘绕布设在第二旋喷扩大体内，第二旋喷扩大体凝固后，锚索部与第二旋喷扩大体之间结合力更强，不容易被分离；在旋喷扩体与第二旋喷扩大体非间隔布设即相互抵靠设置时，第二旋喷扩大体抵靠在旋喷扩体底面上，进一步增加了锚固部的锚固力。
