Lock pipe is often used as connection joint in the construction of diaphragm wall. After pouring concrete, it often fails because of poor control of drawing time. In this paper, combined with an engineering example, the post-treatment of drawing fracture is described in detail. During the construction, it is necessary to chisel out the locking pipe on one side of the foundation pit and the nearby concrete, then cut off part of the locking pipe, make reinforcement cage in the excavation groove, weld with the original connecting wall reinforcement, and pour concrete to cover it. The possibility of rust and expansion of residual locking pipe was analyzed, and the treatment method was verified to be effective by the use of several years later.
