At 20:49 on December 16, after more than 70 hours of hard fighting by rescue personnel, the 220 thousand volt Tongyuan Line I of Yuncheng, Shanxi Province, which was out of service due to ice and snow disasters, was re-electrified, and important users and all residents in Yuanqu County resumed normal power supply in an orderly manner.
In this race against time and race against time in the rush repair, a large number of singing and crying, lovely and respectable outstanding personnel have emerged, among which the construction personnel who climb the tower are known as a group of "people who are harder than hard bones".
Tower No. 42 is about 40 meters high, located in a mountain pass of Zhongtiao Mountain, and the scene is constantly windy, with instantaneous winds reaching eight or nine levels. Xu Hao and his companions of the State Grid Shanxi Power Transmission and Transformation Company can only wear thick cotton clothes to work on the tower for 20 minutes each time, and they must be replaced, otherwise they are very likely to freeze on the top of the tower.
On the tower, they fastened their seat belts, adjusted their body positions, and used a long wooden stick to rhythmically beat the wires, shaking to remove the ice from the lines little by little. When the wind hit, they hugged the tower, closed their eyes, held their breath, and continued their work after the wind had passed. In the event of a long period of strong winds, in order to ensure personal safety, you can only retreat to the ground first and then make a new departure.
Although the position of Tower 40 is low and the wind is slightly weak, it has brought great difficulties to the emergency repair due to the severe icing. Li Kuiming, a tower climber and a member of Linfen Power Supply Company, said: "There are about 50 foot pegs in an iron tower, and the ice on the foot pegs must be removed first for each step, and then the next one must be removed after stepping on the foot, and at the same time, it is necessary to carefully observe the stress of each tower material to see if there is deformation and distortion, so as to judge whether it can continue to climb, so that it takes half an hour to reach the top of the tower at the earliest, which is more than 20 minutes slower than usual, and the physical consumption is very large." ”
"People often refer to power grid builders as "iron army" and "iron man", which is not an exaggeration. We all felt very cold and shivered when we stood under the tower, and they were so tenacious that they were working continuously on the tower. Many people at the scene sighed.
"People in our industry often say that those who can hold on to the tower for two or three minutes are people with good physique, and those who can hold on for 5 minutes are definitely hard bones. These repairers are definitely harder than hard people. Wei Lifeng, an expert in on-site power grid construction management, said.
In order to repair this line as soon as possible, Yuncheng Power Supply Company tried every possible way to do a good job in logistics support and give the greatest care to the tower operators. They provided the scene with boiled hot eggs, heated milk, beef, as well as warm stickers, knee pads and other edible products, and placed gas stoves on the site to supplement the physical fitness of personnel, facilitate personnel to warm up, and prevent frostbite.
As of press time on the 17th, the emergency repair personnel began to repair the rest of the faulty lines, and once again plunged into a new and more difficult battle. (Source: Shanxi Daily)
