At 10:28 a.m. on December 4, accompanied by the roar of ceremonial salutes, the pouring of the first underwater bored pile for the main pier of the Xiangjiang No. 7 Bridge by the Fourth Company of CCCC Second Harbor Engineering Co., Ltd. officially began. After eight hours of intense and orderly construction, the concrete pouring was successfully completed, marking the prelude to the main bridge construction.

The pile poured this time is Pile 0# of Main Pier 14# (pile No. K2+342), with a pile top elevation of 27.75 meters, a pile bottom elevation of -9 meters, a pile diameter of 3.6 meters, and a single-pile concrete volume of nearly 400 cubic meters. To successfully pour this highly significant pile, the project department made meticulous arrangements and full preparations, ensuring the timely arrival of equipment, personnel, and concrete. The successful pouring of the first bored pile marks the official start of substructure foundation construction for the Zhuzhou Xiangjiang No. 7 Bridge and lays a solid foundation for the comprehensive and smooth construction of subsequent works. The Zhuzhou Xiangjiang No. 7 Bridge project is a bridge crossing the Xiangjiang River, located in Tianyuan District, Zhuzhou City, about 400 meters upstream of the Lushui-Xiangjiang confluence and about 5 kilometers downstream of the Zhuzhou Navigation and Hydropower Complex. The approach bridge is designed with a width of 35 meters, the main bridge with a width of 28 meters, and the bridge length is 957 meters, with a maximum single span of 90 meters. The project cost is 206 million yuan, and the construction period is 24 months.
