Recently, the No. 3 work zone of Section 4 in front of the station of the Changsha-Ganzhou High-Speed Railway, undertaken by CCCC Road & Bridge Construction, successfully completed the pouring of the 1,000th pile foundation, smoothly achieving the milestone target 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 boosted the quality, efficiency, and pace of the entire Changsha-Ganzhou High-Speed Railway project.

The Changsha-Ganzhou High-Speed Railway is a key infrastructure project that connects Jiangxi and Hunan provinces, improves the layout of the high-speed rail 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 zone 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 unfavorable factors such as a long local rainy season, high rainfall frequency, a large scope of land acquisition coordination, and concentrated cross-operation of multiple processes, this poses enormous challenges to the quality, safety production, and ecological and environmental 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 based on 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 briefings, on-site inspections, and tiered acceptance, and finely 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 adhered to the bottom lines of green infrastructure and civilized construction, and coordinated the advancement of project construction and ecological protection. All construction workers 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 triple bottom lines of safety, quality, and environmental protection.

The successful achievement of this 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 engineering 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 rail project, continuously empowering the upgrading of transportation in the revolutionary old areas and injecting strong infrastructure momentum into regional high-quality development.
