Zhangzhou Nuclear Power Units 3 and 4 Trench Civil Engineering Completes Milestone Phase

Zhangzhou Nuclear Power Units 3 and 4 Trench Civil Engineering Completes Milestone Phase

On August 27, with the final cubic meter of concrete poured into place, the B1 and B6 sections of the GS and GB trench civil engineering works for Zhangzhou Nuclear Power Units 3 and 4, undertaken by CNNC Huachen, along with the No. 4 overflow well, successfully completed their milestone phase. This phase involved multi-disciplinary cross-operations spanning civil works, installation, electrical, and piping, characterized by complex construction conditions and significant coordination challenges. Among these, Section B1, as the project's main critical path, featured narrow working areas, difficult access for large equipment, and intensive vertical and horizontal cross-operations among multiple units. Seven days before commencement, the project department established a dedicated planning team to verify site conditions, material routes, and cross-operation scopes drawing by drawing, identifying key difficulties such as foundation pouring, equipment positioning, and material supply, and conducting multiple rounds of discussions to optimize the construction plan. The construction period coincided with the rainy season, and Section B1, situated in a low-lying area, faced a high risk of rainwater backflow. The project department implemented measures including full-coverage rain shelters over the base slab, water-retaining curbs at passage openings, and round-the-clock pumping in two shifts, securing dry working areas amid accumulated water; simultaneously, discarded waterproof membranes were collected and reused to cover rebar cages and scaffolding, preventing corrosion and slippery conditions. On-site daily meetings were held, management personnel maintained 24-hour duty, and verbal confirmation with signed handovers was practiced, ensuring issues were resolved the same day, with no plan failures, rain-related stoppages, or process disconnections throughout the period. Facing the immense scheduling pressure from multi-process cross-operations, the project department established a dynamic scheduling system. In terms of manpower loading, fixed posts and personnel quotas were implemented, with zonal responsibility and flexible reinforcement; during peak periods, core work crews were consolidated and work areas were precisely delineated. For machinery, a dynamic scheduling ledger was established, with tower cranes, excavators, and lifting equipment staggered and cross-utilized. Material coordination was also optimized through advance stocking, zoned storage, dedicated management, and emergency replenishment. During the campaign, when the transport of main materials was obstructed, the project department organized management staff and labor crews to manually carry rebar, pipes, and auxiliary materials point-to-point to the working areas, effectively safeguarding project progress. Currently, the main structure construction of the GS and GB trenches by the Zhangzhou Nuclear Power Project Department has achieved phased results, with the GB trench completing 74 sections cumulatively, an 82% completion rate, and the GS trench exceeding 1,160 meters, accounting for 72% of the total length. The company will further strengthen construction organization, optimize construction logic, and continue to advance the remaining sections of the Zhangzhou Nuclear Power Project Department, fully ensuring high-quality performance of the contracted projects.
