Method for lowering and pulling joint pipes of anti-seepage construction wall

The invention discloses a method for lowering and pulling joint pipes of an anti-seepage construction wall. The method comprises the steps that first joint pipes are lowered at the two ends of a groove hole respectively and locked through a pipe drawing bench; a lower joint pipe is positioned and connected to the first joint pipe in some optional embodiments; in some optional embodiments, the lower joint pipe is relocked by the pipe drawing bench after being lowered in place; concrete is poured until a tail joint pipe is lowered in place; and pulling is carried out at a set time interval after the concrete is poured for a set time. The method for lowering and pulling the joint pipes of the anti-seepage construction wall aims at solving the problems that the lap joint thickness of a groove hole and the hole inclination control difficulty are large during construction of the anti-seepage wall. 本发明公开了一种防渗施工墙的接头管下放及起拔方法，包括：在槽孔的两端分别下放首节接头管并用拔管机锁定；定位下节接头管并连接在一些可选的实施例中首节连头管、在一些可选的实施例中下节连头管；在一些可选的实施例中下节接头管下放到位后用拔管机重新
