On September 13th, near the patriotic tunnel of Asanon County, Sichuan, the green Dadu River water, 3 wires with a length of more than 500 meters across the Dadu River. With the operation of the power workers swaying in the air, the metal was shot after the sun was illuminated by the sunlight. Unique luster. "The arc is adjusted." "Pulling the line is normal." At 13:56, the State Grid Zigong Power Supply Company Luding Earthquake Rescue Team is adjusting the vertical arc of 10 kV Caotian Line 49+1 to 50, and will soon recover to recover. Electric arteries leading to Xingfu Village, Yexian County.

Two days ago, the rescue team surveyed on the spot, and finally finalized on the flat ground near the patriotic tunnel. The new three -linked three -link connection was connected to No. 50. The newly -established three -link.

"The repair plan has been settled, but I encountered a problem on the electric pole hole and the pull -line cave." Tang Ming, the person in charge of the site work, watched the cave that had been playing 7 working hours and shook his head. "The geological conditions here and the Zigong area here are It is completely different. It is a layer of firm stone and a layer of sand. It can only rely on excavators to dig pits, but the excavator is to grab the road. We can only fight the holes artificially.

"We resumed power supply earlier, and the affected people could use power and light up the lights earlier." The anxious Tang Ming turned around with a tape measure, and measured the depth and width of the electric pole hole and pulling cave one by one. After 3 working hours, 3 electric pole caves have construction conditions. Tang Ming, who had been waiting for a long time, immediately took the rescue team to step forward. Within an hour, the 3 -base electrical pole was successfully completed.

"There is still a difficult point in this construction. The distance from the 49+1 to 50 is more than 500 meters. There have been rescue vessels from the cross -river section to shuttle back and forth, which cannot affect normal navigation. It is difficult to cross the river crossing." introduce. The rescue team urgently contacted the State Grid Ya'an power supply company to coordinate a special drone for the construction of the power construction line. In the end, the third -level traction rope is then across the river with a wire. In the roar of the twisted burst, after six hours of intense operations, the three -stage guide line cross the river crossing. At 15:16, the front section of the 10 kV Caotian Line and the happiness branch of the happiness branch were normal.

At this point, the most complicated geological conditions encountered by the rescue team and the most time -consuming task of the repair work have been successfully completed. The rescue team overcame the difficulties of multiple overlapping difficulties such as Jianshi Hengsong, Mountains, and Dadu River Navigation Rescue, and completed on -site surveys, material transfer, and on -site construction.

As of 20:00, the rescue team completed the main line and 9 branches of 10KV Caota Line No. 28 -95 and the corresponding 14 platforms. Wait for 19 rescue tasks.
