Voice of Chongqing August 3 News Entering August, the mountain city of Chongqing ushered in a continuous high temperature weather, and the meteorological department continuously issued a high temperature orange warning. In order to ensure the safety of railway operation, front-line workers put on the hot steel rails above their heads and stepped on the hot steel rails, sweating between the rails to carry out equipment inspections.
The Chongqing Industrial and Electrical Section of China Railway Chengdu Bureau Group Corporation mainly has jurisdiction over the Chongqing North Railway Station Hub, Yuli High-speed Railway, Yuwan High-speed Railway and part of the Xiangyu Line, and is responsible for the maintenance and repair of railway engineering, signaling, power supply, communications and other infrastructure.
At 9:00 a.m. yesterday (2), at the Chongqing North Railway Station, more than a dozen workers and masters in the industrial and electrical section had been working outdoors for more than 4 hours. Zhang Zhongyong, a turnout maintenance worker, said that in order to avoid the high temperature, the workers went to the construction site at 5:30 a.m. and finished at 11:00 p.m., during which they had to complete the day's inspection tasks with quality and quantity.
The reporter saw at the scene that under the scorching sun, workers wore straw hats, long clothes and trousers and thick gloves between the railway tracks to beat and measure data. Zhang Yongzhong said that the staff is divided into several groups, one group of personnel carrying a ruler to check the geometric size of the turnout, and several other operators with a wrench followed by checking whether the bolts are loose one by one to ensure that the size of each part of the turnout frame is good. Other operators measure the resistance voltage of the turnout insulation joint to prevent the poor insulation from causing the red light belt of the track circuit and affecting the EMU in and out of the garage.
"We also have an important job to prevent the orbit from 'expanding the orbit'." Zhang Zhongyong said that under the scorching sun, every time the track temperature rises by 1 ° C, the rail will be extended by 0.0118 meters, if it is not "anti-inflation", the straight track will bend, so in order to ensure the safety of train traffic, there will be people on the track at any time.
On the long railroad tracks, there is no place to escape the scorching sun, the steaming heat wave on the line forces people to breathe, the workers and masters are wet and dry, dry and wet, sometimes sweat can only be wiped into the eyes, and the work on the hands is not stopped, and there is not even time to drink water. "Although the weather is unusually hot, it is our responsibility and mission to see the trains passing safely and smoothly, so that passengers can travel in comfort." Zhang Zhongyong said.
