Henan Daily Client reporter Hu Dacheng Henan Daily All -Media reporter Yang Jingjing correspondent Liu Yuanxin

On September 8th, at the construction site of the 110KV line of Chucheng, Hezhai, Xinyang, Henan, the tension field of the Beijing -Guangzhou Railway was pulling two 240/30 steel core aluminum twisted lines, passed through the 19th iron tower, slowly pulled towards it slowly, and slowly pulled towards it. The top of the tower on the 20th.

"This operation site spans the Beijing -Guangzhou Railway, which is a secondary risk operation." Mei Hongyu, the Ministry of Construction of the State Grid Xinyang Power Supply Company, introduced it at the scene, "As an owner, the State Grid Xinyang Power Supply Company supervised the whole process of the construction site. , Ensure that the project is put into production safely on schedule. "

The reporter looked at the direction of Mei Hongyu's fingers, and two sides of the Beijing -Guangzhou Railway had already stood up with two leap -up frames from all steel frame structures. Overlooking from the sky, the two cross -racks were linked by a large network across the railway. The offline train passed from time to time, and the scene was spectacular.

How is such a spectacular scene realized?

It is reported that in order to ensure the normal operation of the railway, the railway sunroof period is only 20 minutes. The load of drones is limited, and it is obviously unrealistic to directly pull the net from Donglu to West. What should I do? The person in charge of the project of the State Grid Xinyang Power Supply Company gave the answer.

"During the 20 -minute sunroof period, we transported the traction rope from the east side of the railway to the west side with the drone. The weight of the traction rope needs to be demonstrated. Hou Yuzhu, director of the Construction Department, said.

After the traction rope reaches the west side of the railway, there is a connection between the two crossing frames. The construction personnel will be tied to the two roundabout ropes on the back to the east side of the railway through the traction rope. Behind the roundabout rope is pulled, 5 main ropes hanging on the insulation network over the railway. The editorial network also opened vertically on these three main ropes. With the advancement of the editorial network, this 67 -meter -long and 16.2 -meter -wide Dinima insulatory network also slowly moved from the east side to the west side to cross the tower. In the end, the two spans the tower into one piece. Finally, it lasted 4 hours. At 7 pm on September 8th, the net work was completed! The work of subsequent pulling wires is also carried out on schedule.

Xinyang Hezhai 220 kV transmission and transmission project is one of the 64 national key revolutionary old district energy guarantee projects issued by the General Office of the National Development and Reform Commission, and it is of great significance to optimize the structure of the northern power grid of Xinyang. At present, the construction of the project is close to the end and is planned to be put into operation in the near future.
