220 kV nuclear three-core nuclear power transmission line at the end of October

At 10 o'clock on the morning of August 11th, the power workers at the construction site of the 220 kV nuclear power plant of the three-door nuclear power plant in Hangu Tong Village, Liujiao Town, were sweating. "Prepare! Pull!" With a loud chant, the three workers standing on the ground slowly pulled up the ropes that tied the arms. At the same time, on the tower 70 meters above the ground, seven power workers were working on Non-stop erection of the hanging cross-arms on the tower.

As a debugging power source for the three-door nuclear power equipment and a standby power source after start-up, the construction progress of the 220 kV three-door nuclear power-hovering transmission line has attracted attention from all walks of life. It is understood that the transmission line from the 220 kV suspended transformer, and finally the Sanmen nuclear power plant, a total length of 26.77 kilometers, the need to build a new 68-pole tower, of which the straight-line tower 38 base, 30 tower tension tower. Routes need to span multiple highways, cableways, houses and various power and communication lines.

According to Tao Dongxiao, director of the project's project department, since the construction of the project started on February 27 this year, the power supply department has deployed elite troops to form a construction commando team to work overtime to grab the construction period. Up to now, the foundation construction of 63 foundation towers and the erection of 32 foundation towers have been completed, and the construction of the line will be started on August 18. According to the current work progress, the project will be completed and put into use by the end of October.

In the past six months since the start of construction, the harsh construction conditions have made Tao Dongxiao feel deeply. Since more than 90% of the area where the route passes is mountainous and quagmire, it has become a common practice for power workers to go over mountains and rivers and drowning across the river. In order to transport a steel structure tower weighing several tens of tons to a hill of inconvenient traffic, construction workers are racking their brains and not only carrying their shoulders and carrying their hands, but also finding the original transport vehicles such as horses and horses. The most impressive time for Tao Dongxiao was on Zheng Gongshan in Xidu Village, Liubu Town. In order to transport more than 20 tons of materials to the hilltop at an altitude of 381 meters, they also specially set up a cableway.

Although the construction conditions are harsh and the work is very hard, this is not the most worrying thing. The most troublesome thing for construction workers is the progress of the project. Due to geographical conditions, the project originally planned to only need 67 base towers to change the line to another base. Because blasting cannot be used in the Sanmen nuclear power plant area, the construction personnel can only use the artificial excavation method to complete the 4-pillar tower in the nuclear power plant. The excavation depth of the 4-base tower must reach 10 meters and the project is quite difficult.

“Although it is difficult, we have all overcome it under the coordination of electric power, township and township departments. We have assured the people of the county that the mission must be completed by the end of October,” Tao Dongxiao told reporters.
