Thanks to CTOnews.com netizens for the clue delivery that you can change your name again! CTOnews.com news on October 31, according to Nanning Railway release, October 26, Nanyu Railway construction site came good news. After two years and four months of continuous struggle by railway builders, the Pancun tunnel was successfully completed. At this point, all 41 tunnels on the Nanyu railway have been completed.

The Nanyu railway has a total length of 193.31 km, with 41 tunnels, with a total length of 39.7km, accounting for 20.5% of the total length of the line. The lithology of the strata along the line is complex and changeable, part of the tunnel passes through the fault fracture zone, and the geological conditions are extremely complex.

The Pancun tunnel, with a total length of 1770.47 meters, is located in Xueyi Town, Hengzhou, Nanning City. the tunnel passes through fault fracture zones and a number of shallow ditches. The surrounding rock of the tunnel is mainly sandstone and mudstone, which is softened after immersion. Tunnel excavation is prone to large deformation, block fall, collapse and other dangers. The construction unit actively tackles the key problems of the tunnel project, co-ordinates the resources of all parties, optimizes the construction organization, adopts reverse pressure backfilling, and then uses temporary horizontal brace, vertical support, advanced pipe shed, radial grouting and other measures to do a good job in advance support, so as to minimize the disturbance to the rock strata, effectively overcome the risks of falling blocks and collapses, and achieve a safe "zero accident" in the process of tunnel construction.

Nanyu Railway, invested by Guangxi Transportation Investment Group and built by Nanning Bureau of National Railway, is the first high-speed railway with a design speed of 350 kilometers per hour in Guangxi. CTOnews.com learned that at present, Nanyu railway project roadbed earthwork, bridge engineering, tunnel project completion volume of more than 90%.

The Nanyu Railway is an important part of the Nan-Shenzhen Railway. After it is put into operation, the travel time from Nanning to Yulin will be reduced from the current one hour and 45 minutes to about 50 minutes.
