The sixth section of the Sino-Russian East Line (Changling-Yongqing) Wangbaohe pipe jacking tunnel was successfully completed! The welding equipment used for the installation and construction of the pipeline in the tunnel is still the "battle-tested" Kumagai pipeline automatic welding machine.

Wangbao River pipe jacking tunnel crossing project is located in Suizhong County, Huludao City, since the start of the construction of Wang Baohe pipe jacking tunnel, due to complex geological conditions, rock strength is excellent (the original design of pipe jacking tunnel is mainly in the strong weathered granite layer, the rock strength is about 30 megapascals, and the actual geological conditions, the pipe jacking tunnel crossing section stone strength of 134 megapascals), fracture water is abundant (water pressure reaches 0.8 megapascals) and other reasons, once a day to jack less than 2 meters, an average of three days to change the knife. In order to overcome the problems of complex geological conditions, strong construction professionalism, high safety and environmental protection requirements and tight construction schedules of the Wangbaohe pipe jacking tunnel, the relevant leaders of the owner visited the site many times and personally deployed the plan.

After the completion of the construction of the Wangbaohe pipe jacking tunnel, the pipeline installation construction in the tunnel will be completed, and the project department of the sixth bid section of the Sino-Russian East Line (Changling-Yongqing) of CNPC (Xinjiang) Oil Construction Branch will organize the welding technology and excellent quality of the elite soldiers "strong generals" to weld the section to ensure excellent quality. The Kumagai pipeline automatic welding machine will follow the PetroChina (Xinjiang) Oil Construction Branch to solidly promote the final completion of the Wangbao River pipe jacking tunnel crossing.
