33,998 person-times, 2,741 additional posts, and track maintenance personnel successfully completed

Rail Transit Exhibition News During the past "Spring Festival" holiday, the maintenance companies planned and deployed in advance, and formulated comprehensive driving measures. According to statistics, a total of 33,998 people participated in the escort, and 2,741 people were added. During the festival, the maintenance personnel still stick to their posts to ensure the safe operation of the subway every day.

During the festival, the maintenance company set up a special working class to make full use of the intelligent operation and maintenance system to monitor and analyze the pantograph monitoring data in real time, and always maintain a keen insight into the abnormal changes in the pantograph-network relationship, thereby effectively reducing the impact of these factors on the operation of the subway.

Behind the scenes of ensuring equipment maintenance, all branches of maintenance have strengthened the daily maintenance and overhaul of key professional equipment. At the same time, behind the scenes of construction, the overall situation of the construction of the maintenance sector is stable, and the daily operation and maintenance are solid and orderly. Each major focuses on key areas with its professional advantages, completes major and special construction with high quality, and closely coordinates and promotes all links. A total of 7,238 construction tasks have been completed, including 2 major constructions: the manual installation of 5G equipment for maintenance and the commissioning of the signal transformation bullet train of Line 3/4.

In view of the low temperature and cold wave weather that may occur during the festival, the maintenance company has also done a good job of tracking and analysis, and formulated practical and effective control measures to ensure the smooth and orderly operation of the subway, and better completed the goal of "six non-occurrence and one control".

Maintenance vehicles

All departments closely focus on the work requirements of "safe Spring Festival, convenient Spring Festival, and warm Spring Festival", strengthen leading cadres on duty, strengthen on-site shift operations and inspections, and command from the front. Set up emergency command points in branches, and set up sub-command points in each maintenance department. Focus on ensuring the facilities and equipment of core lines, core periods, and core stations, improve the capacity of relevant lines of "four stations and two fields", and do a good job in ensuring the opening of the first train.

According to the maintenance requirements and characteristics of facilities and equipment, strengthen the frequency of on-site inspections, and focus on the inspection of train doors, PIS systems, train air conditioning and other systems. At the same time, it strengthens the linkage between the digital collaboration center of the main line and the operation crew, makes full use of intelligent operation and maintenance and other means to improve the efficiency of troubleshooting and emergency response, and effectively ensures the safe, stable and reliable operation of the subway.

Maintenance of power supply

Focus on strengthening the line duty force of the first and end traction stations of each line, the traction stations of the main line entry and exit sections, hub stations, and signal concentration stations. Combined with the cold weather, the branch carried out special inspections on the ground and elevated catenary and power cables, adjusted the maintenance strategy in time, and effectively prevented the impact of temperature changes on the power supply equipment.

The professional multi-functional team of substation and the professional repair team of the network are on standby 24 hours a day to strengthen the emergency response and operation support capabilities under extreme weather to ensure the safe and stable operation of the power supply system.

Maintenance number

In terms of equipment support, the production dispatch of the branch office, as the overall commander of the production emergency of the whole network, coordinates the resources of the whole network for night construction, operation safety, emergency disposal, etc., and connects with the dispatching command center, operation and brother units in a timely manner, so as to do a good job in collaborative linkage and information flow, and ensure a quick response within 15 minutes.

In terms of construction control, during the festival, the group focused on key projects such as the overhaul and reconstruction projects of Lines 3 and 4 and the 5G public and private network projects, and always maintained a state of "non-stop". In order to ensure the safety of construction, the maintenance department takes the middle platform as the core to control the whole process of key construction of the lines under its jurisdiction.

Maintenance and public works

Focus on the inspection and maintenance of key facilities such as rail lines and turnouts, use digital inspection tooling, and refine the status analysis and preventive maintenance of facilities and equipment.

The maintenance staff is watching the New Year at their posts and building the warmest way home for the city. When the last train passes through the silent tunnel, the sparks of the maintenance lights are connected into the Milky Way on the ground, which is a wordless love letter written by the subway maintenance person to the city, and it is the most beautiful New Year's painting outlined with professional ingenuity. They embodied the word "peace" as the stability of the train, the abundance of electric energy, the accuracy of the signal, and the smoothness of the rails, so that every expectation for the Spring Festival arrived at the terminal safely.
