(Summary description)The pipe jacking machine should be installed and debugged once before installation, and the tubing should be cleaned before installation to prevent dust and other dirt from entering the tubing. The circuit system should be kept dry, all parts of the machine head running and debugging should operate normally, and the hydraulic system should not leak. The size and structure of the pipe jacking machine should be checked in detail before hoisting. When hoisting the pipe jacking machine, it should be steady and slow to avoid any impact and collision. Use a large crane to use a special spreader to ensure safety and reliability. After the pipe jacking machine is placed on the guide rail, measure the direction deviation and relative height difference of the center of the front and rear ends, and make a record. The contact surfaces of the pipe jacking machine must be consistent with each other. Connect the roadheader to the circuit, oil circuit, water circuit, air pressure, mud pipeline and control system one by one. All components are required to be installed correctly, connected firmly, and no leakage. After installation, each sub-system is required to be carefully inspected and trial run , To achieve normal operation.
