Method for sealing end of pipe curtain of jacking pipe

The invention discloses a method for sealing an end of a pipe curtain of a jacking pipe. According to jacking pipe tunnel construction, steel edge waterstop belts are installed on lining walls and jacking pipe tunnel three-linings in the earlier stage, grouting sealing is carried out, steel plates are welded and plugged to the end of the pipe curtain in the later stage, concrete filling is carriedout, waterproof roll paving is carried out, water sealing wall construction is carried out, grouting sealing is carried out, and the pipe curtain is sealed. According to the method, the steel edge waterstop belts effectively enable a dark excavation section, an inner lining wall and a water sealing wall to form a single waterproof and drainage system, later water seepage disposal risks are conveniently prevented, the water seepage treatment cost can be effectively saved, in addition, the pipe curtain cannot be damaged by the plugging manner, the safety of the tunnel structure is facilitated,and a reserved grouting pi
