The Xiangjiang extra-large railway bridge of the Shichang Railway found that the catenary was covered with ice and asked for support. At about 10 o'clock in the evening of February 21, Tan Tianlai, the person in charge of the catenary maintenance workshop of the Changsha power supply section of the Guangzhou Railway Group, received an urgent call.
The Xiangjiang super-large railway bridge of Shichang Railway connects the two trunk lines of Jiaoliu and Beijing-Guangzhou, and is an important channel for the southern transportation of coal from Shanxi and Henan, with more than 90 passenger and freight trains passing through the peak period every day.
Since February 20, the first cold wave of the Year of the Dragon has affected Hunan, freezing rain and sleet in Changsha and surrounding areas, and the catenary of the Xiangjiang extra-large railway bridge and the surrounding equipment have been covered with ice, and the pantograph on the train is easy to break due to overload, which affects the safety of the train.
After receiving the dispatch order, Tan Tianlai quickly went to the scene with the staff of the Laodao River catenary work area to guard and observe, and urgently contacted the skylight to prepare for artificial ice.
At about 5 o'clock in the morning of the 22nd, before dawn, the temperature had plummeted below zero. Tan Tianlai, who was on duty for more than 7 hours, and his party of 4 people set off for the Xiangjiang Bridge to carry out ice breaking operations.
At 7:16, after receiving the notice of permission to work, four people climbed onto the platform of the operation vehicle. On the bridge deck, the biting cold wind hit, and Tan Tianlai couldn't help but shiver.
The platform of the operation truck slowly rises to the same height as the catenary. "Everyone stuck the buckle of the seat belt in a firm place, it was very windy today, so you must pay attention to safety. Tan Tianlai shouted to the workers.
The work truck traveled at a speed of 3 kilometers per hour, and everyone stood on both sides of the iced contact line, holding wooden sticks, and took turns to beat the contact line. The cold wind kept "whapping" their faces, and the low temperature made their feet tremble, but their hands did not stop, repeating the simple but laborious action of "knocking on the ice".
After more than 1 hour of fighting, 1The de-icing operation of 4 kilometers of catenary line was successfully completed.
Scheduling, the ice-breaking operation of the Xiangjiang extra-large railway bridge between Wangcheng and Xiufeng has been completed, and the train can pass safely. Tan Tianlai's hands were red from the cold, and he picked up the walkie-talkie to report the operation.
Not long after, a train passed over the Xiangjiang extra-large railway bridge. Tan Tianlai and his entourage watched from afar, with a relieved smile on their tired faces.
