CTOnews.com March 27 news, Southwest Railway official Weixin Official Accounts today updated the article, announced that with the first pair of 500 meters long rails safely and steadily laid on ballast track ballast, Hanbanan Railway Nanchong to Bazhong section officially entered the track laying construction stage.

Nanchong-Bazhong section of Hanbanan Railway is located in the northeast of Sichuan Province, with a total length of 148.04km and a design speed of 250km/h.104 bridges and 53 tunnels will be newly built, with a bridge-tunnel ratio of about 69%.6 stations including Nanchong North Station, Muba Station, Yilong Station, Ma 'an Station, Enyang Station and Bazhong East Station will be set up. The construction period is 4.5 years. It is expected to be completed and opened to traffic in 2024.

CTOnews.com learned from the Southwest Railway official that the track laying project of Nanchong to Bazhong section of Hanban-Banan Railway includes the construction of ballasted track, ballastless track, ballasted turnout and ballast along the whole line. The total length of track laying on the main line is about 298 kilometers. At present, ballasted track can be laid 1.5 to 2 kilometers per day, ballastless track can be laid 4.5 to 6 kilometers per day, and it is planned to complete the construction task of track laying along the whole line by the end of September this year.

In addition, in order to ensure the safe and smooth progress of track laying construction, the Hanbanan Railway Bid 6 Project Department of China Railway Fourth Bureau has invested 32 fixed group cranes, 6 mobile gantry cranes, 80 railway flat road vehicles, 1 WZ500 ballastless track laying unit, 1 ballastless tractor, 1 CPG500 intelligent track laying unit, large-scale maintenance tamping equipment and other intelligent track laying equipment. During the peak construction period, 7 track laying operation surfaces can be constructed simultaneously. More than 900 people work at the same time.

At the same time, CPG500 intelligent rail laying unit invested in rail laying can increase the mechanization degree by 90% compared with the traditional rail laying mode, reduce the dependence on the number of auxiliary operators by 63%, significantly reduce the number of auxiliary personnel, reduce labor intensity, save construction costs and shorten the rail laying period.

After the project is completed and opened to traffic, the shortest operation time from Bazhong to Nanchong and even Chengdu and Chongqing will be greatly shortened.
