Deep stratum diaphragm wall pouring joint pipe and pipe drawing method
The invention relates to the technical field of geological treatment and water conservancy construction, and particularly discloses a deep stratum diaphragm wall pouring connector pipe and a pipe drawing method.The connector pipe comprises a connector pipe body formed by mutually nesting and buckling a first half pipe and a second half pipe, and the first half pipe body is composed of a first arc-shaped side wall and a first nesting part; the second half pipe is composed of a second arc-shaped side wall and a second nesting part, and the cross section of the second arc-shaped side wall is composed of an arc-shaped section located in the middle and linear sections integrally connected to the two ends of the arc-shaped section. The pipe drawing method comprises the steps that the second half pipe and the first half pipe are sequentially drawn, resistance is gradually overcome, the drawing force is reduced, the drawing smoothness and success rate are improved, and the problem that the connector pipe is stuck is solved. Under the condition of the same pipe diameter and depth of the joint pipe, pipe drawing can be completed with lower pulling force.
本申请涉及地质处理，水利施工技术领域，具体公开了深地层防渗墙灌注接头管及拔管方法，接头管包括由第一半管和第二半管相互嵌套扣合形成的接头管，所述第一半管由第一弧形侧壁和第一嵌套部组成，所述第二半管由第二弧形侧壁和第二嵌套部组成，所述第二弧形侧壁的横截面由位于中部的弧形段和一体连接于弧形段两端的直线段。拔管方法包括依次起拔第二半管和第一半管，对阻力逐步克服，降低起拔力，提高起拔的顺畅性和成功率，解决接头管卡滞，卡死的问题。本发明在相同接头管管径和深度的条件下，可以以更低的起拔力完成拔管。
