Our company undertook the construction tasks of all pier pile foundations (including land piles on both sides of Xiangjiang River, diameter 1.8m~2.5m, 136 rock-socketed piles) of Hunan Xiangtan Yiyang Highway Bridge in March 2016. As the bridge is located in the bare rock area of the Xiangjiang River, a steel cofferdam is installed on the water pier according to the design requirements.
