Construction method of diaphragm wall

The invention discloses a construction method of a diaphragm wall. The construction method comprises the steps that surveying and setting out are conducted; a construction platform and a guide wall are constructed; a groove hole is formed, and primary cleaning is conducted on the groove hole; a reinforcement cage joint pipe is placed and a guide pipe is poured; secondary cleaning on the groove hole is conducted; wall concrete is poured; and the reinforcement cage joint pipe is jacked and pulled. The construction method of the diaphragm wall aims at solving the problem that the construction period is long due to the fact that the technology is tedious in the construction process of the diaphragm wall. 本发明公开了一种防渗墙的施工方法，包括：进行测量放样；对施工平台及导墙进行施工；开设槽孔并对其进行一次清理；安放钢筋笼接头管及浇筑导管；对槽孔进行二次清理；浇灌墙体砼；顶拔钢筋笼接头管。该防渗墙的施工方法的目的是解决防渗墙施工过程工艺繁琐导致工期长的问题。
