According to the introduction of the research and development personnel, Shield Machine No. 001 of China Railway Shanhe belongs to the composite soil-pressure balanced shield, with a total length of about 90 meters and a weight of about 500 tons, the main drive adopts the liquid-driven type and is equipped with 8 sets of hydraulic motors, which has a high driving power, and is equipped with a 6-main beam composite cutter, which has an outstanding digging capacity. At the same time, the shield machine also adds the ventilation and cooling system and soil silo visualization system and shield tail gap measurement system independently developed by China Railway Shanhe, and the safety performance of the equipment is effectively guaranteed during the construction process.

“This is already the fourth time that Shield Machine No. 001 of China Railway Shanhe has been on the road.” After-sales service engineers said that this “battle-hardened” shield “veteran” has participated in the underground construction of two intervals of Changsha Metro Line 5 and Guangzhou Metro Line 11 between 2017 and 2021, providing a great help for the successful completion of the project. The project has provided a great help for the successful completion of the project. The participation in the Yueyang Municipal Conduit Corridor project is a reflection of the project's recognition of the strength of the shield machine.

It is understood that the Yueyang city government pipe corridor project west from the central substation, east to the east of Wangjiahe Bridge, a total length of about 4.5 kilometers, Yueyang City, the first soil pressure balance shield construction as the main body of the project, after the completion of the Yueyang City, the central city of the electric power system will greatly improve the capacity to help complete the “three years to recreate a new Yueyang Power Grid” goal, to solve the problem of power supply tension, enhance the quality of urban life of the people. Solve the problem of power supply tension in Yueyang city, improve the quality of the city and people's quality of life.

This time, the shield machine No. 001 of China Railway Shanhe tunneling interval is from Wangjiahe Bridge to Jianxiang Road, with a total length of about 2,400 meters, and the shield adopts a split start, with an excavation diameter of 6.28 meters, and the tunneling process mainly crosses the hard rock strata of medium-weathering and micro-weathering. Despite the hardness of the strata, it is hard to resist the strong 001.

Next, as the equipment provider, China Railway Shanhe will always adhere to the epidemic prevention and control and safe production, rationally coordinate resources to ensure stable and efficient operation of the equipment, and contribute Shanhe's strength to the construction of this major people's livelihood project.
