Precast concrete jacking pipe joint in vault straight wall structural form

The utility model provides a precast concrete pipe-jacking section in a vault straight wall structure form, which relates to the field of pipeline engineering and comprises a top plate, a bottom plate and two side plates, the top plate is a vault, the bottom plate is a flat plate, the side plates are straight plates, and the top plate, the bottom plate and the two side plates are connected in a smooth transition mode to form the pipe-jacking section. A steel bellmouth is arranged on the circumferential outer side of one end of each pipe-jacking section, an insertion opening is arranged on the circumferential outer side of the other end of each pipe-jacking section, and the insertion opening of the rear pipe-jacking section is inserted into the steel bellmouth of the front pipe-jacking section, so that the front pipe-jacking section and the rear pipe-jacking section are fixedly connected. Compared with a traditional concrete pipe joint for pipe jacking, on one hand, the top plate is of a vault structure, exter
