China News Network Yulin, September 2 (Tan Yujun Qin Zhenbin) At 00:00 on September 1, Li Zhan Line Guangxi Yulin Station to Yulin's second range of 144 kilometers outside the fence, crowded people, there was no wind in the dark night, and the air was sultry. China Railway Nanning Bureau Group Co., Ltd. Yulin Working Section gathered nearly 100 employees in 6 teams in 6 teams in Yulin Line workshop, and preparations for replacing more than 500 meters long rail bunches on the fence.

"Today we will complete construction operations such as more than 500 meters long rails and welded rails in 180 minutes. The time is very tight. Everyone should be in place and move quickly according to the task." Lu Chaoqiang, deputy director of the line workshop, loudly arranged construction tasks.

At 1:20, the construction order was issued, and the on -site protectors quickly set up protection. The employees carried the machine materials and rushed to their respective work sites.

"Da Da Da, One Two One ..." A crispy machine sound and powerful hooded schemes broke the night sky, and the echo was echoed over the line.

This time the rail change must first cut the old rails on the line and then dial out of the line, and then allocate more than 500 meters long new long rails into the rail tank. Such a long rail is difficult to dial in.

In order to make various operations in an orderly manner, the workers are divided into eight operational groups including the rail cutting group, the welding steel rail group, the buckle finishing group, the crowbar rail dialing group, and the inspection and acceptance group. Essence The fastener organizer first launched 4 screw oil coating machines to manipulate the machine quickly to release the fastener. Several employees followed closely, and Mali cleared the nut and buckle out of the pillow groove.

Su Yongneng, the leader of the welded rail group, fixed the saw track to the rail, cut the measured marking into the rail, cut the saw blade and the rail, and made a "nourishing" sound. The sparks on the scene bloomed dazzlingly.

After the cutting is completed, the orbital group is lined up in the word "one", inserting the crowbar into the bottom of the rail. The long new steel rails pushed up, and the force was moved together to make it accurately "lie" in the pillow groove. The old rail all turned from the other end to the shoulders.

Subsequently, the welded steel rail team immediately carried out operations such as rails, molding, and pre -heating. "Ready to ignite, everyone is a little far away from the welding machine, pay attention to the spark." Su Yongneng reminded everyone loudly. Just listening to the "bang", the blue flame with a temperature of 1200 degrees Celsius was sprayed out of the welded rail heater, and the welding head became more and more red. The heat waves generated by the flames and rails rushed towards the operator, and the soaked workers were gradually dried.

200 seconds, 280 seconds, and 300 seconds, the flame in the heater gradually extinguished, and the welded seam was completely merged together. Cooling, positive fire, reinforcement, fine grinding ... "The smoothness of the connector is 0.1 mm." Su Yong could put away the welding seam straight ruler and congestion and report to the person in charge of construction.

After 5 minutes, the welding operation ended. After pushing tumor, polishing and other processes, the welding of the rail joints is completed, and the detection meets the standard.

Other group personnel are also fully rolled out, installing fasteners, rehabilitation bolts, checking track parameters, recycling old materials ... Live operations are busy and orderly.

At 4:10, the construction operation of the rail change was all over, and the employees of the labor section successfully completed the rail change construction task 10 minutes in advance. (Finish)
