November fifth，After more than 900 days of hard work，Invested by Zhejiang Communications Group、Shanghai Railway Bureau Coastal Railway Zhejiang Co., Ltd. Agent Construction Management、The whole line control project of Qu-Li Railway undertaken by China Railway Tunnel Engineering Group——Quzhou-Lijiang RailwayIThe section from Lianlin inclined shaft to the main tunnel of Baiankou transverse tunnel of Biaofengshuling Tunnel was successfully completed，It marks a solid step forward in the construction of Quli Railway Project.，The project has achieved a phased victory.，It has laid a solid foundation for the whole tunnel of Fengshuling Tunnel.。

Qu-Li Railway is a national medium and long-term railway network planning project and a multi-level rail transit planning project in the Yangtze River Delta.，It is also a comprehensive implementation of the construction of Zhejiang Grand Garden.、Supporting the Development of Eco-tourism Belt in Southwest Zhejiang、It is an important project to fill the gap of high-speed railway network in southwestern Zhejiang.。The total length of Qu-Li Railway is 160.1 km，The total investment is 267.200 million yuan，It shall be implemented in stages。

The total length of Fengshuling Tunnel is 15.185 kilometers，According to the new double line、The design speed is 200 kilometers per hour，Reserve 250 kilometers per hour for construction，The maximum buried depth is about 935 meters.，Crossing 14 faults、5 densely developed joint zones and 3 intrusive contact zones，There is a high ground temperature、High ground stress，It is easy to collapse during construction.、Mud burst and water gushed、Soft rock deformation、Rock burst and other geological disasters，The geological conditions are extremely complex.。The total length of the section from Lianlin inclined shaft to Baiankou transverse tunnel is 5516 meters.，Among them, the single-head tunneling length of Baiankou transverse tunnel in the direction of small mileage is 3027 meters.。

The Qu-Li Railway is scheduled to open to traffic in 2027.，From Quzhou to Lishui by train than the original 1..The five-hour drive is shortened by about 40 percent%，Only 55 minutes.，Will completely open up central China、Southwest China passes through Quzhou and Lishui、Convenient transportation channel between Wenzhou and other areas，Will be connected with Quzhou-Jiujiang Railway、Jinwen Railway and other related railways together constitute the north of Jiangxi.、Convenient access to the sea in southern Anhui and Hubei provinces，To improve the layout of the road network in southwest Zhejiang、Promote the rapid development of Wenzhou port，Promoting industrial transfer along the Yangtze River Delta、Achieve integrated economic development、Promoting the leap-forward and high-quality development of 26 counties in mountainous areas，It is of great significance to help build demonstration zones for common prosperity.。（Economic Daily reporter Qi Hui）
