China Railway Indonesia Yawan High Speed Rail News!
The China Railway Indonesia Yawan High-speed Railway project made another good news. The No. 5 tunnel of the Yawan High Speed Rail has been successfully completed, which is also the completion of the second tunnel of the China Railway Yawan High Speed Rail Project.
Yawan High Speed Rail No. 5 Tunnel is 422 meters long and is a shallow buried tunnel, all of which are clayey, with poor self-stabilizing ability and complicated geological conditions. In order to ensure safe construction, the tunnel uses advanced geological prediction and surrounding rock monitoring and measurement technology to ensure safe and rapid construction of the tunnel. After many technical breakthroughs by engineers, it was finally determined to adopt the three-step temporary inverted arch method to overcome the difficulties of shallow tunnel burial and weak surrounding rock. Through short footage, strong support, diligent monitoring, and quick adjustment, the tunnel construction safety and safety were ensured. Excavation progress. Aiming at the deep and steep terrain of the gully where the bridge and tunnel at the exit of Tunnel No. 5 meet, the project department breaks the rules, adjusts the plan, improves the equipment, solves the transportation difficulties, and successfully completes the construction of the large pipe shed to ensure the safety of the exit. During the construction of the tunnel, 79 Indonesian tunnel skilled workers were also trained, which played an important role in the construction process and will soon become the main force in the construction of the Yawan high-speed rail.
During the new coronavirus epidemic, personnel and materials were restricted from going to Indonesia, which exacerbated the already difficult rainy season construction. However, the China Railway Indonesia Yawan High-speed Railway Project Management Department has united its minds to work together to adhere to overseas construction and production positions, implement its original mission with practical actions, solidify epidemic prevention and control, and resolutely promote construction and production. The tunnel was completed and the actual production value was exceeded. The epidemic prevention and control and construction and production were two-handed, two-handed, and two-handed.
Tunnel No. 5 is an important node in the advancement of the tunnel project. The timely completion of the tunnel further reflects the determination of the China Railway Yawan High-speed Railway construction team to advance the project progress on time, and also more effectively promotes the overall process of the Yawan High-speed Railway project construction.
China-Indonesia's comprehensive cooperation on the Yawan High Speed Rail is an important step forward in the "21st Century Maritime Silk Road" initiative and an important landing project of Indonesia's "Global Ocean Fulcrum" strategy. This project is the "first order" for China's high-speed railway to go abroad, from technical standards, survey and design, engineering construction, equipment manufacturing, material supply, to operation management, talent training, and comprehensive development along the line. The Jakarta-Bandung high-speed rail has a total length of 142.3 kilometers and a maximum design speed of 350 kilometers per hour. After completion, the driving time will be shortened from more than 3 hours to more than 40 minutes.
