China News Service, Lanzhou, February 27th (Feng Miaomiao, Qijianfei, Zhu Xuecheng) "The traffic density during the Spring Festival is high, and the line equipment will appear 'fatigue' after a long time of rolling. To improve the quality of the driving equipment, the line should be repaired in a centralized manner after the Spring Festival every year." Zhang Yanhong, deputy section chief of the Dingxi Works Section of the Lanzhou Railway Bureau, who was monitoring the safety of construction operations on site, said.
On the 27th, trains of rail grinding vehicles stepped on the "hot wheels" on the Longhai Railway Tianshui to Lanzhou section of the railway line. The grinding operation of the large mechanical vehicle line between the Gansu Wangjiawan Station and Xujiatai Station of the Longhai Railway has begun.
From February 26 to April 6, the first phase of the Longhai Line within the jurisdiction of Lanzhou Railway Bureau was intensively repaired and constructed.
The Tianshui-Lanzhou section of the Longhai Railway was built in 1946. It is the choke point from Central China and East China to the Northwest, and also the Silk Road Avenue for China-Europe trains. It ensures that the excellent railway equipment is good for the safe operation of trains and the speed of the trains. Running is crucial.
The centralized repair construction task is heavy and the organization is difficult.
In order to improve the accuracy of the centralized repair construction plan, the Lanzhou Railway Bureau anticipated and planned carefully in advance, carried out thorough on-site investigations, formulated project plans by classification, refined and improved the promotion plan, and improved the operability of the construction plan.
Dingxi Public Works Section, Lanzhou Public Works Machinery Section and other construction units closely cooperated to strictly control all aspects of construction preparation, registration, dispatch orders, safety protection and train release, and to strengthen the refined management of operations to ensure personal and traffic safety during construction.
"This year's intensive repair, we specially organized 15 large excavators to replace 7,402 sleepers on the 4.4-kilometer line between Tianshui and Yangjiahe in the mode of large-scale operation. It used to take 120 seconds to replace one, but now a large The excavator can be replaced in 45 seconds, and the operation efficiency has been greatly improved." Cui Huifeng, chief of the technical section of the Dingxi public works section, introduced.
At the same time, in view of the fact that the centralized repair points are multi-line long and the whole line is blooming, Dingxi Public Works Section, Lanzhou Public Works Machinery Section and other units have established special working groups such as on-site inspection, construction plan coordination, video monitoring, and cadre style supervision. More than 1,000 people participated in the construction, formulated emergency plans scientifically and rationally, gave full play to the role of the control center, and carried out full coverage and monitoring of all major maintenance construction operations during the centralized repair period to ensure that key construction links, key positions and key personnel are under control everywhere , Always be safe, and make every effort to ensure the complete success of the centralized repair construction.
