Enhance quality awareness and promote high-quality development. ----------------------------------------- On March 19, 2022, the direct pipe-laying crossing project along the Xingfu River in Section 9 of the China-Russia East Gas Pipeline Project (Yongqing-Shanghai), specifically in the Tai’an-Taixing area, was successfully completed. This project set four national records in China: the longest crossing distance for direct pipe laying (701 meters), the greatest progress per shift (98 meters), the greatest progress per day (191 meters), and the average daily progress (45.2 meters).
The China-Russia East Route natural gas pipeline is currently the largest in diameter and highest in pressure among China’s long-distance natural gas transmission pipelines. It is also a major strategic project for global natural gas cooperation. The pipeline is being constructed in three sections: the northern section (Heihe in Heilongjiang–Changling in Jilin), the central section (Changling in Jilin–Yongqing in Hebei), and the southern section (Yongqing in Hebei–Shanghai). During the construction of the northern and central sections, the Pipeline Bureau set itself the goals of \"fully digital handover, fully intelligent operation, and full-life-cycle management.\" It successfully applied newly developed equipment, processes, and technologies in all stages of pipeline construction, thereby improving the quality and efficiency of the project. In the southern section of the China-Russia East Route, the Pipeline Bureau won bids for Contracts 4 and 5 of the Anping-Tai’an section, Contracts 1, 3, 4, and 7 of the Tai’an-Taixing section, and Contract 3 of the Nantong-Luzhi test section. The direct pipe laying crossing project over the Xingfu River in Section 9 of the Tai’an-Taixing section is a key project that restricts the construction of the southern section. The pipe diameter is 1,219 millimeters, and it passes through geological formations such as silty clay, silty mud clay, gravelly silty clay, silt, and silty sand, making the construction process highly challenging.
