Two months in advance than the original plan!Hengyong high -speed Qishan Tunnel's left hole is smoothly connected

Hengyang News Network reporter Li Yangjie correspondent Liu Xianjun Peng Jianyun Yuan Dongwei reported on August 11, the reporter's Zihengyang City Transportation Bureau learned that a few days ago, the left cave of the Qishan Tunnel from Hengyang to Yongzhou Highway was successful. The goal of Hengyong Expressway was established in 2024.

As the key control project of the Hengyong Expressway project, the Qishan Tunnel runs through the Qishan Mountains and connects Qiyang City and Qidong County. It is the only long tunnel on the entire line. The design is a separate dual -line tunnel with a length of 2,550 meters on the left and a length of 2630 meters on the right. The terrain along the way is large, the mountains are narrow, the slope is steep, the geological structure is complicated, and the construction organization is more difficult. To this end, the construction party uses a number of "wisdom" construction technology during the construction process. The tunnel construction adopts intelligent mechanical jet equipment, which can automatically identify characteristic structures such as arch, protective nets, and super excavation of the surface of the tunnel. Automatically adjust the jet mode during the construction process to complete the spray on the tunnel surface with high efficiency and low loss consumption. Operation. Informatization intelligent two -lined buildings, the intelligent operation of data visualization completes the concrete pouring in the tunnel, solves the unsightly problems of conventional two -lining construction forming streamlines, and improves the quality and efficiency of construction. In order to effectively enhance the awareness of self -protection of workers, the project department has set up a safety experience hall at the entrance of the tunnel to allow the front -line construction staff to experience safety production and emergencies in the "immersive" and improve the effectiveness of safety education.

The Hengyong Expressway is the encryption line planned by the "Seven Episodes and Nine Heng" highway network in Hunan Province. It is a golden channel connecting Hengyang and Yongzhou. District, Hengnan County, Qidong County.

According to the relevant person in charge, the right hole of the tunnel is expected to penetrate in October. After the completion of the tunnel, it will greatly shorten the straight -line distance between Hengyang and Yongzhou, which will improve the investment environment in the region, promote the economic integration of the southern Hunan Demonstration Zone, and enhance the overall competitiveness of the region.
