Recently, the Songjiang Plant of China West Construction (Shanghai) Co., Ltd. successfully completed the concrete pouring for the first C30 underwater pile at Pier P3 of the W3 Connecting Road (railway-crossing section) project of the Shanghai Songjiang Hub, with a depth exceeding 100 meters. The project includes a total of 16 large pile foundations with depths exceeding 100 meters and concrete volumes exceeding 300 cubic meters each, more than 30 pile foundations with concrete volumes of 100-200 cubic meters, and a total concrete demand of approximately 9,000 cubic meters.

Since the contract was signed, in order to fight this "professional battle," "quality battle," and "brand battle," the Songjiang Plant quickly established a technical research team led by the chief technical engineer and composed of technical department heads. Starting from aspects such as raw material selection, mix proportion optimization, and admixture performance adjustment, the team focused on adjusting key indicators such as concrete workability, setting time, and time-dependent loss, specifically addressing challenges including cohesiveness under high-drop impact, good working performance for more than 3 hours, and retarding time matched to the construction schedule.

During the pouring period, in order to control the pouring progress in real time, the Songjiang Plant leadership team communicated and directed on site, with all departments coordinating and working together, strictly controlling quality, service, and safety. Through the joint efforts of all personnel, the large pile foundation pouring process was smooth and successful, with zero complaints throughout the entire process, receiving unanimous recognition and praise from the project owner, construction contractor, and supervision unit.

It is reported that the newly built W3 Connecting Road (railway-crossing section) project of the Shanghai Songjiang Hub is an important rapid transit channel for the Songjiang South Railway Station hub. This connecting road spans the newly built Shanghai-Kunming Railway and the newly built Shanghai-Suzhou-Huzhou Railway, and is a landmark project of the Songjiang Hub. Going forward, the Songjiang Plant will continue to carry out technical and quality control work, using high-quality products and the best service to help the Songjiang Plant build the West Construction brand on this project.
