Problems solved by technology

[0004] The purpose of the present invention is to propose a "golden cicada shelling" type rectangular pipe jacking construction method for the problems existing in the prior art, aiming to solve the shelling process by adopting quick plugging by laying bricks at the end and fast replacement of cement grout under pressure In order to improve the deformation resistance of the steel shell, the casing frame is used to weld the longitudinal steel plate in the rectangular cast-in-place concrete lining to improve the deformation resistance of the steel shell. Waterproof and drainage construction joints to solve the waterproof problem of the joints between the cast-in-place concrete lining and the main structure

Abstract

The invention discloses a periostracum cicada shelling type rectangular jacking pipe receiving construction method. The method comprises the following steps that drilling detection is conducted; a ground wall is chiseled and a cutter head soil bin is cleaned; a temporary hole is plugged; pipe jacking equipment is dismounted; preparation before pouring is carried out; a bottom plate and short side wall formwork is erected, and concrete is poured; side walls are welded with a bin dividing steel plate of a top plate; reinforcing steel bars are bound and welded, and a formwork is erected; concrete is poured under pressure; and a guide type waterproof and drainage construction joint is arranged. According to the construction method, the longitudinal bin dividing steel plate is welded to a machine shell frame, the deformation resistance of a steel shell is improved, micro-expansion self-compacting concrete is adopted for under-pressure pouring, and the concrete pouring quality and efficiency are guaranteed; and the guide type waterproof and drainage construction joint is arranged between a cast-in-place concrete lining and a prefabricated segment, and therefore, the waterproof problem of a joint between cast-in-place concrete and an existing structure is effectively solved.

Description

technical field [0001] The invention relates to a pipe jacking construction method for an entrance and exit channel of an urban subway station, in particular to a "golden cicada shelling" type rectangular pipe jacking construction method. Background technique [0002] Pipe jacking construction technology mainly originated in Japan and European and American countries. Due to its high construction efficiency, small construction disturbance, and small footprint, it is widely used in the construction of urban underground passages and underpasses. With the further development of urban construction, the above-ground and underground spaces in the city are becoming more and more crowded, which can ensure the starting and receiving space of pipe jacking construction is also decreasing day by day. Under special circumstances, it is impossible to arrange the pipe jacking receiving well, and the pipe jacking machine can only be received in the existing underground buildings. Due to the...
