On August 6, according to the introduction of Chengdu Rail Construction Management Co., Ltd., the lines under construction planned to be completed in 2020 are undergoing acceptance, handover and other work on a large scale. Among them, the first and second phases of line 6, the third phase of line 6, the first phase of line 8, the first phase of line 9, the first phase of line 17, the first phase of line 18, and the second phase of line 18 will all be completed and put into operation .

Phase 1 and Phase 2 of Line 6

At 23:00 on August 4, with the completion of the "hot slip" test in the mid-section of the first and second phases of Line 6, all the "hot slip" tests on the entire line were successfully completed, which also laid a solid foundation for the handover of the entire track area and the no-load trial operation. basis. At the same time, 800M coverage of the dedicated wireless communication system for the first and second phases of Line 6 has been completed, and the line has entered the state of wireless communication.

Phase 3 of Line 6

The third-phase power supply system of Line 6 achieved 130 kilometers of ring network cable laying and power transmission within 45 days, and achieved a 100% pass rate of the power supply system before the handover of the rail area, which provides a solid guarantee for the stable operation of the entire power supply system . The post-station engineering (electromechanical installation and decoration, etc.) of this line has gradually moved from the stage of joint commissioning and joint testing to the stage of actual acceptance of unit engineering.

Line 8 Phase I Project

With the completion of the handover of the track area of the last section of the first phase of Line 8, the handover of the track area of the entire line has been completed, laying the foundation for the no-load commissioning of trains.

Phase 1 of Line 9

Following the overall handover of the Wuqing Depot, Yuanhua Parking Lot and the first batch of stations at the end of May, and the handover of the entire track area in mid-June, the handover of the second batch of stations was completed recently. So far, 10 stations of the first phase of Line 9 have been handed over. With the continuous advancement of all-point testing and system joint debugging of all stations on the whole line, conditions have been created for no-load trial operation.

At present, all-point testing and system joint debugging of 13 stations, Wuqing Depot, Yuanhua Parking Lot and the whole track area on the whole line have achieved a pass rate of over 98% of the system joint debugging at each station on the whole line.

Phase 1 of Line 17

Following the completion of the overall transfer of the first batch of stations, Jinxing Station and Huangshi Station, recently, the second batch of stations also completed the overall transfer of the City Fifth Hospital Station, Wenquan Avenue Station, and Mingguang Station. Relevant dispatching and command rights, territorial management rights and equipment use rights were smoothly transferred from the construction unit to the operating unit.

Phase 1 and Phase 2 of Line 18

The fire inspection and acceptance was divided into two batches, and on-site inspections were carried out on all stations, sites, entrances and exits, main stations and part of the track area of the first section. The first batch involves 4 stations including South Railway Station and Incubation Park Station. The second batch involves 6 stations including Haichang Road Station and Hejiang Depot.

The acceptance team unanimously agreed that the quality of the fire protection project in the first phase of the first and second phase of Line 18 was qualified, the linkage function met the fire protection requirements, and the relevant information was complete, and agreed to pass the acceptance.

After these seven lines are put into operation, the comprehensive three-dimensional development of the Chengdu rail transit hub will be further strengthened, the urban traffic structure will be optimized, the sustainable development of Chengdu rail transit will be promoted, and the development of the new Chengdu-Chongqing land-sea corridor will be facilitated.
