Recently, the No. 3 Work Area of Section 4 in front of the station of the Chang-Gan High-Speed Railway, undertaken by CCCC Road & Bridge Construction Co., Ltd., successfully completed the pouring of the 1,000th pile foundation, smoothly achieving the milestone of 1,000 pile foundations and marking a key phased achievement in the project's foundation construction. The successful completion of this 1,000-pile construction task effectively resolved bottlenecks in foundation construction, created the prerequisites for the subsequent batch construction of pile caps and pier shafts, and strongly supported the quality improvement, efficiency enhancement and accelerated construction of the entire Chang-Gan High-Speed Railway line.

The Chang-Gan High-Speed Railway is a key infrastructure project that connects Jiangxi and Hunan provinces, improves the layout of the high-speed railway network in central China, and supports the revitalization and development of the revolutionary old areas of Hunan and Jiangxi. It is of great significance for optimizing the regional transportation pattern and driving economic development along the route. Among its sections, the No. 3 Work Area of Section 4 in front of the station, located in the red old area of Yongxin, Jiangxi, is a key and difficult section of the entire line. The construction area has a complex geological environment, with alternating soft and hard rock layers and widespread soft soil foundations. Combined with the long local rainy season and high rainfall frequency, as well as unfavorable factors such as the large scope of land acquisition coordination and the concentration of multiple cross-process operations, this has brought great challenges to the quality, safety production and ecological environmental protection control of pile foundation construction.

Facing complex construction conditions, the project team adhered to scientific construction and precise control, optimized the special pile foundation construction plan in light of actual site conditions, and coordinated the allocation of construction resources such as personnel, machinery and materials. The project established a full-process quality and safety control system, strictly implemented standardized management measures such as technical disclosure, on-site inspections and tiered acceptance, and carefully controlled key processes including hole formation, hole cleaning, reinforcement cage installation and concrete pouring, effectively overcoming the difficulties of pile foundation construction in complex geology and building a solid defense line for engineering safety and quality.

During construction, the project upheld the bottom lines of green infrastructure and civilized construction, and coordinated the advancement of project construction and ecological protection. All builders seized the construction window period, worked continuously day and night, efficiently resolved various construction difficulties, and completed the 1,000-pile foundation construction task to high standards while strictly observing the three bottom lines of safety, quality and environmental protection.

The smooth achievement of the 1,000-pile foundation milestone is an important milestone in the project's foundation construction, marking a substantive breakthrough in the project's offline foundation construction and laying a solid foundation for the full-scale and orderly advancement of subsequent main works. Next, the project department will continue to deepen refined, standardized and green construction management, closely follow construction milestones, strictly control project quality and safety, refine construction deployment, steadily advance construction tasks at each stage, and strive to build a safe, high-quality, green and efficient premium high-speed railway project, continuously empowering the upgrading of transportation in the revolutionary old areas and injecting strong infrastructure momentum into regional high-quality development.
