Foundation reinforcement of buildings in Taiwan region of China

This project involves multiple civil buildings in Taiwan, China. Due to issues such as uneven settlement and wall cracking in the buildings, as well as the need for renovation, after structural assessment, it was decided to adopt the 98 helical pile foundation replacement technology for foundation reinforcement. The blades are welded to the pile ends and the pile bodies, serving as a drilling guide, to distribute soil pressure and provide some uplift resistance. The aim is to transfer the load of the upper structure effectively to the deep and stable soil layer by implanting high-strength helical piles, thereby controlling and correcting settlement and ensuring the long-term safety of the buildings.
Typical challenges: Soft clay layers, fill soil layers, sand layers and high groundwater levels are common in Taiwan, which can lead to insufficient foundation bearing capacity or seepage damage.
Earthquake factors: Located in an earthquake-active zone, the reinforcement plan needs to significantly enhance the foundation’s seismic resistance and anti-liquefaction ability.
Construction restrictions: Minimizethe impact on the original structure: Construction vibration and noise need to be strictly controlled to avoid secondary interference to the existing structure and the lives of residents.
