[0022] A hinge seat 8 is fixed to the lower front end of each of the two square tubes I1. One end of each of the two square tubes II9 is ​​hinged to its respective hinge seat 8. The other end of each of the two square tubes II9 is ​​fixedly connected to a nut. The nut is threaded to one end of a stud B10. Another nut is also threaded onto the stud B10. The other ends of the two studs B10 are inserted into the limiting bracket 11.

[0023] The frame 6 includes square tube Ⅲ601, connecting tube A602 and square tube Ⅳ603. The two square tubes Ⅲ601 are arranged vertically and spaced apart. The upper ends of the two square tubes Ⅲ601 are fixedly connected to two spaced connecting tubes A602. Between the two connecting tubes A602, a square tube Ⅳ603 is fixedly connected to the back of each of the two square tubes Ⅲ601.

The hydraulic device provides power, and the piston rod of the hydraulic cylinder 12 is connected to the pipe jacking tool 16. The extension of the piston rod drives the pipe jacking tool 16 to advance. The distance between the two well openings is one meter, and the pipe jacking tool 16 can advance a distance of half a meter to perform unblocking operations inside the pipe. Through the advancement of the pipe jacking tool 16, the blockage intensity of the blockage in the pipe is effectively reduced. After this operation is completed, the original working method is used to continue the unblocking operation of the pipe. In this way, the blockage in the pipe between the two well openings can be completely cleared, ensuring the smooth flow of the pipe.
