Shallow buried excavation does not affect ground facilities
The reporter interviewed Jiang Jianping, director of the Infrastructure Department of Lanzhou Power Supply Company, and learned that in the 110 kV Xiguan Cross cable tunnel of Lanzhou Power Grid, the construction department adopted the “shallow-buried, undercut†construction method. Experts believe that the design and construction of the project has effectively reduced the environmental problems such as surface movement and deformation caused by the loss of stratum, minimized the impact on the surrounding environment, and improved the construction quality and speed. Since the construction site is along the Yellow River Line of Sightseeing, the pedestrians of the vehicles are denser. The use of "deep-buried dug" will not affect the vehicles, pedestrians and ground facilities, and it will also facilitate the maintenance and repair of power grids in the future. According to expert scientific analysis, the 110 kV Xiguan Cross cable tunnel adopts the method of “shallow-buried and dug†construction, which has low cost, does not require much special equipment, does not interfere with the ground traffic and the surrounding environment, and has significant social and environmental benefits.
It is understood that the "shallow buried excavation" construction method was first applied in the construction of electric power facilities in Lanzhou, and it will surely gain first-hand information and accumulated rich construction experience. It will be the future of various municipal projects and urban underground facilities in Lanzhou. Construction has played a positive and guiding role.
Cable entry will further enhance the image of the city
According to Jiang Jianping, director: "According to the design plan, plans a total investment of 230 million yuan of the West Gate Cross 110 kV transmission substation, will further enhance the emergency response capacity of the power grid in Lanzhou City, West Gate Cross-powered dredge weaknesses, reliability of power supply for the region and The safety of power supply is guaranteed. According to reports, the new 110 kV Xiguan Cross Substation cable tunnel of Lanzhou Power Grid goes from the first vertical pit on the west side of the Lantan River in Lanzhou to the west along the Nanbinhe Road to Qilihe Wujiayuan, and the length of the tunnel 4120 m, where the length of the main tunnel is about 4,120 meters and the length of the tunnel is about 950 meters.
Is it only necessary to build new cables into this section? The reporter learned from the provincial power company that, in accordance with relevant requirements, the new wire and cable in Lanzhou will be planned to enter the ground in the future to reduce the impact of high-altitude overhead lines on the overall image of the city. For the north and south Binhe Road of Lanzhou City, as a scenic line of the city, the provincial power company has communicated with the relevant departments of the province and plans to connect all the cables of Binhe Road in the north and south to the land to further beautify the Binhe Road. However, due to the large amount of funds involved, consultations are currently under way.
