en.Wedoany.com Reported - On June 4, the final bridge pile foundation concrete was poured and formed in the Chaozhou East to Chaoshan Station section of the Eastern Guangdong Intercity Railway's Lot 8, Sub-lot 2, marking the full completion of bridge pile foundation construction in this section.
This project is invested by Guangdong Provincial Railway Investment Group, led by China Railway South China for construction management, and undertaken by China Railway First Group. The completion of this milestone has fully cleared the construction channel for beam erection in the section, laying a solid foundation for the comprehensive advancement of subsequent main structure works.
It is understood that the total length of the Lot 8, Sub-lot 2 line of the Eastern Guangdong Intercity Railway is 11.35 kilometers, with 2,340 designed bridge piles, including 95 end-bearing piles and 2,245 friction piles, all constructed using the bored pile method, with pile diameters ranging from 1 meter to 1.25 meters, and the entire construction process employing rotary drilling technology for hole formation.
The project is located in the Chaoshan region, where the geological environment is extremely complex. The groundwater level in the area is high, and the strata mostly consist of flow-plastic muddy soil and sand layers. During the pile hole drilling process, construction difficulties such as hole collapse, necking, and sand gushing are prone to occur. Controlling hole formation accuracy, optimizing mud slurry indicators, and managing hole wall protection are extremely challenging, imposing high demands on construction techniques and on-site management.
Since the start of construction, the project team has anchored to the overall construction milestone targets set by the Eastern Guangdong Intercity Railway Company. Leveraging the construction advantages of the Fuyang Station pilot section, they scientifically formulated a construction plan of "tackling easier tasks first, then difficult ones, and advancing steadily." The project department introduced professional hole formation detection equipment to collect, analyze, and dynamically monitor key data such as pile hole formation quality and construction parameters throughout the process, ensuring full traceability and controllability of the entire pile foundation construction, and striving to build a safe, high-quality, premium, and reliable project.
Upon completion, the project will establish a "30-minute commuting circle" for the three cities of Chaozhou, Shantou, and Jieyang.
