Railway departments firmly promote centralized maintenance and equipment spring inspection to lay a solid foundation for safety

In May, a number of lines including Beijing Guangzhou, Beijing Jiulong, Jiaoliu, Jingha, Shenshan, Daqin, Lanxin, Hukun, Tanghu and Jinshan were intensively repaired. Combined with the current weather characteristics, the railway department constantly optimizes the construction organization, grasps the key construction links, and ensures the construction safety, order and control.

In April, the construction of centralized repair of the whole road went smoothly. The construction of centralized repair of Beijing Shanghai, Longhai, Shide, Shitai and other lines has been completed in an all-round way, with 921 kilometers of track replacement and sleeper replacement completed, 14000 kilometers of line cleaning, tamping and rail grinding completed, 7538 groups of turnout replaced, polished and tamped, and more than 2700 kilometers of contact network maintained. The construction of capacity expansion and reconstruction of special transportation channel of Beijing Harbin railway is carried out in order according to the plan.

In view of the fact that severe weather such as high temperature and heavy rainfall occurs frequently in May, according to the requirements of China National Railway Group Co., Ltd., each railway bureau group company strengthens the construction organization, completes the pre construction risk assessment, and refines the construction scheme and flood control emergency measures. For the construction affecting the stability of the line, all units shall strictly implement the construction regulations in flood season and the rail temperature operation conditions of the CWR, and shall not start the construction if it does not meet the safety conditions; for the construction involving interlocking management, LKJ basic data replacement, and large machinery adjacent to the business line, the key inspection and monitoring shall be strengthened. The dispatching department shall further coordinate the transportation and construction, strengthen the organization of interface handover during the centralized repair construction, timely adjust the loading direction, make full use of the overall capacity of the road network, reduce the construction impact, and promote the loading volume.

In April, the locomotive and vehicle department carried out the spring repair of locomotives, EMUs and buses in an orderly manner. A total of 14941 locomotives were identified and 14461 locomotives, 3153 EMUs and more than 35000 buses were repaired. Focusing on the high-speed railway and bus routes, the Department of industry and electricity carried out spring inspection and inspection on the equipment of industry and electricity, and carried out two rounds of full coverage inspection and inspection on the high-speed railway and the six general speed trunk lines.

In May, each equipment management department strengthened the inspection and monitoring of equipment operation status, and continued to solidly promote the spring inspection and spring appraisal. Combined with the current weather characteristics, all units further strengthen the work of rail expansion prevention, wind prevention, lightning protection, bird prevention, etc., promote rail expansion prevention in key sections, do a good job in monitoring and reinforcement of the frost damage falling section, strengthen the adjustment of technical parameters of the contact network, organize the inspection and testing of lightning protection equipment; focus on the inspection and remediation of environmental hazards along the high-speed railway, such as dust-proof net, plastic film and other light floating objects Promote the anti expansion work of the spring melt falling track and rail in key sections, strengthen the adjustment of the technical parameters of the catenary, strengthen the detection and monitoring of the equipment operation status, and ensure that the main driving equipment is in good condition.
