August 8th

Changjing Yellow high -speed rail control project-

Yaoli Tunnel goes smoothly

It laid a solid foundation for the operation of the entire line

The total length of the Yaoli Tunnel is 9736.49 meters. The Yaoli Tunnel spans the two provinces of Anhui and Jiangxi. Among them, it is 8,803 meters in Jiangxi Province and 933.49 meters in Anhui Province.

The maximum buried depth of the Yaoli Tunnel is 481 meters, and the shallow part is only 6 meters. The geological conditions are complicated and the construction conditions are difficult. It is a level I risk tunnel.

In order to ensure the safety of construction, the construction unit uses the engineering test information management system and the quality management platform of mixing stations to implement the full -process management and control of the informatization process, and introduce various steel components for centralized machinery and equipment; "Change me" to ensure that the tunnel is safe and high -quality.

At the same time, the builders were constructed at the same time in multiple working planes such as Baocun Hengdong and Wangjiazhuang, which effectively guaranteed the progress of the project. After 1185 days of continuous fighting, the Yaoli Tunnel achieved smoothly.

The Changjing Huang high -speed rail started from Nanchang, Jiangxi to Huangshan, Anhui, and the line was about 290 kilometers in length, and the design speed was 350 kilometers per hour.

The Changjing Huang high -speed rail spans the Poyang Lake Plain and runs through the Huangshan Mountains. It is a beautiful tourist scenery. After the Changjing Yellow high -speed rail is completed and opened to traffic, another high -speed rail artery that connects the long triangle of Jiangxi will be formed, which is of great significance to promote the economic construction and development of the Poyang Lake Ecological Economic Zone, improve the regional high -speed rail transportation network, and drive the development of the tourism industry along the line.
