Recently, the third phase of Chengdu Rail Transit Line 18.
The city (suburban) railway is the Meimei line.
There is a new development.
Recently, the successful completion of the laying of the third phase of the existing catenary cable of Chengdu Rail Transit Line 18 marks the successful completion of the laying of the longest existing high-voltage cable of Chengdu Rail Transit so far, laying a solid foundation for the next stage of the catenary.
The laying of the existing catenary cable of the third phase of Line 18 was completed.
The total length of the third phase of Chengdu Rail Transit Line 18 is about 16658km, is the extension of the first and second phases of Line 18 to the central urban area and the north of the airport, which will connect the main urban area of Chengdu, Sichuan Tianfu New Area, Chengdu Eastern New Area and Tianfu International Airport after completion and opening to traffic.
The third phase of Line 18 is located in the existing rail area of the first phase of Line 18, which has been put into operation, starting from South Railway Station, passing through Incubation Park Station, Jincheng Square East Station, Century City Station, Haichang Road Station, and finally Haixi No. 1 Wind Shaft between Haichang Road Station and Xibocheng Station. A total of 6 cables with a length of 90,562 meters are laid in this section, which is the number one "difficulty" of the project, which is difficult to coordinate construction, must apply for power outage operations at night, complex path conditions, and high safety pressure. It is reported that the whole line of Line 18 has a long running distance, and according to the design specifications, when the power supply of the northern section of the third phase of Line 18 is out of normal operation, it needs to be supported by the adjacent main power supply. However, due to the fact that the first and second phases of Line 18 and the third phase of Line 18 do not belong to the same batch of construction planning lines, the first and second phases of Line 18 have not implemented the catenary support power supply cable of the third phase of Line 18 in the early stage, so it is necessary to lay cables in the existing operating lines of the first and second phases of Line 18.
Recently, 10 times of 500kV ultra-high voltage power lines (between Sencha Station and Hongbei Station) of the Chengdu to Meishan Line Project of the Municipal (Suburban) Railway, Shantao Line 34 successfully completed the line relocation, passed the on-site acceptance and successfully transmitted, marking the successful completion of half of the ultra-high voltage power lines of the S5 line, and refreshed a number of records in Chengdu rail transit construction.
The total length of the eyebrow line is about 59139km, a total of 13 stations (including 8 elevated stations, 5 underground stations), after the completion of the line, will accelerate the interconnection of infrastructure in the Chengmei area, and promote the sustainable development of regional economy and society.
The relocation and reconstruction of Chengmei Line includes 10 times of 500kV ultra-high voltage power lines of Shantao 1234 Line, Shanpeng 12 Line, Penglin (formerly Jiapeng) 12 Line, and Popeng 12 Line, and the successful relocation and reconstruction of the project provides a strong guarantee for the subsequent civil construction of S5 Line.
