Waterproof pipe jacking structure for pipeline construction

The utility model discloses a waterproof pipe jacking structure for pipeline construction, which belongs to the field of building construction and comprises a wellhead body, a sealing plate, an anti-bending component, steel plate corner tucks, a pipe joint, a steel lantern ring and a water swelling ring. The sealing plate and the wellhead body are flexibly connected through the tongue-and-groove after wellhead pouring is completed, the sealing plate is more firmly limited to the wellhead body through the steel plate corner, the sealing plate and the anti-bending component jointly resist water and soil pressure at the position of a hole in the position of the wellhead body, and when pipe joints of a jacking pipe are laid, the steel lantern rings are embedded between the pipe joints, so that the pipe joints are prevented from being damaged. A water expansion ring is installed between the two steel lantern rings to prevent water leakage between the pipe joints, measurement is conducted once when the pipe joints
