The left line of Selong Tunnel 1 is smoothly connected

The left track of Selong Tunnel 1 is 840 meters long. Since the construction of the tunnel on May 24, 2022, various participating units have focused on the goal of creating a "safe century quality project", pressed and compacted the responsibilities of all parties, conducted in-depth analysis and research on key and difficult construction technologies, and continuously optimized and adjusted construction plans based on actual conditions. Relying on the project information construction management platform, comprehensive monitoring, timely investigation and elimination of various safety hazards, high standards Strict requirements for strengthening construction technology and process quality control have overcome construction geological problems such as loose and broken surrounding rock, and high soil moisture content, effectively ensuring efficient tunnel construction and excavation.

The construction of the same competition project will continue to increase the efforts to create a century long quality project for Ping An, implement the requirements of the three refined management improvement activities, and accelerate the completion of annual target tasks in project construction.
