In order to enhance the service brand image of Changzhou Metro's "People's Metro Centennial Metro", from June 18th to 20th, Changzhou Rail Transit Line 2, which was built by China Railway 14th Bureau Electrification Company, held a grand "Ten Thousand People Test Ride" event. , A gift to the 100th anniversary of the founding of the party. During the trial rides, Line 1 is free at the same time, the enthusiasm of the citizens is high, and the passenger flow is constantly refreshed. As of noon on June 20, the passenger flow of Lines 1 and 2 has exceeded 640,000.

The first phase of the Changzhou Metro Line 2 project runs from the center of the city west to Wuyi Road in Qi District. It runs from east to west and is about 19.86 kilometers long. It has 15 stations, including 14 underground stations and 1 elevated station. The Electrification Company of China Railway 14th Bureau is responsible for the mechanical and electrical installation and decoration construction of Lucheng Station, Wuyi Road Station and adjacent sections of this line. Among them, Wuyi Road Station is the only elevated station on Changzhou Metro Line 2.

Since entering the site, the project department has planned in advance, carefully organized, overcame difficulties such as tight schedules and multiple cross-operations. By strengthening communication and coordination with the owner, and scientifically organizing construction, it has achieved a high starting point. Among them, the Lucheng Station starts from the three adjacent facilities. The construction and various process models are the first to lead the construction of the whole line as a model station. The project department adheres to the leadership of party building and actively carries out the "Party building and co-construction and labor competition" activities, establishing a "red flag responsibility zone" for party members, and organizing employees to set off a great upsurge to ensure The project opened as scheduled.

During construction, especially in view of the complex spatial layout of the platform, the various professional systems, the disorderly layout of equipment and pipelines, and the collision of pipelines, the project department fully applied BIM technology to construction and production, using the model design capabilities of BIM technology and on-site integration The ability and construction “rehearsal” function integrates professional models such as architectural structure, electromechanical major, strong current major, and weak current major, to visually and three-dimensionally display the connection between the overall construction process, and detect possible conflicts through collision detection. Make adjustments in time for collisions that have occurred.

During the construction, the three-dimensional model was used to optimize the layout of the integrated support and hanger, the cable tray, and the integrated pipeline to avoid more than 20 collisions. Compared with the traditional construction plan, it effectively reduced the total cost of the project by 3% and saved the total cost. 5% of the construction period, the three improvements of project progress, construction process quality, energy saving and consumption reduction have been successfully achieved, which not only saves costs, but also avoids the waste of construction period caused by rework, and also provides a solid technical guarantee for the construction of high-quality projects.

It is reported that after Changzhou Metro Line 2 is completed and opened to traffic, a cross-shaped traffic skeleton will be formed, which will further relieve urban traffic pressure, stimulate urban construction, optimize the urban structure, and further shorten the distance between east and west in Changzhou, which greatly facilitates the travel of surrounding citizens.
