(Summary description)The main jack pump station and the main jack cylinder are an indispensable part of the pipe jacking construction, and provide sufficient propulsion for the nose and the pipeline to advance. Technical features: 　　 1. Multi-interface, and can realize linkage with the machine head. 　　2. The pumping station is controlled by a single pump to realize two different speeds of cylinder expansion and contraction. 　　3. The pump station adopts double pumps and double motors, with high pressure, large flow and convenient maintenance. 　　4. The oil cylinder seals are sealed with high polyurethane, which has high pressure resistance, excellent wear resistance and good sealing performance. 　　5. In the construction of trenchless long-distance pipe jacking, the relay room assembly is placed at regular intervals to reduce the long-distance and large-tonnage jacking force in sections, and reduce the jacking force of the main jacking cylinder and the bearing force of the backrest of the working well.
