the other end of the jacking pipe cylinder is fixedly connected with and penetrates through the cylinder support, the other end of the jacking pipe cylinder is in threaded connection with one end of the pressure testing push head, and the other end of the pressure testing push head is provided with a pressure testing steel pipe.

The utility model is further provided with: the jacking pipe oil cylinder is sealed with the guide sleeve through a group of YX-type sealing rings.

The utility model is further provided with: the cylinder rod of the jacking cylinder is a hollow cylinder.

The utility model is further provided with: the number of the YX-type sealing rings in one group is 2.

The utility model is further provided with: and the cylinder rod is used for connecting the cylinder body and the jacking cylinder.

The utility model is further provided with: the device is suitable for the steel pipe journalism hydrostatic test of which the steel pipe is less than 273 mm.

The utility model is further provided with: the YX type sealing ring of the water injection system is a standard YX ring.

The beneficial technical effects of the utility model are as follows: in the scheme, through the design of a pipe jacking water injection system of the high-pressure medium-high-pressure hydraulic press, the integrated design of a pressure testing push head driving oil cylinder and a water injection pipeline is adopted, and the water injection problem of the steel pipe moving push head is solved.
