Qiubei Independent Energy Storage
Constructed in 2024
Benefits:
- Flexibility in design to satisfy both the structure’s stability and the client’s aesthetic requirement
- On-site materials were utilised, reducing the need for import of structural soil for earthwork
- Mechanically stabilised layer eliminated costly ground improvement
The client needed a reliable solution to build a battery energy storage station (BESS) over closed depressions and valleys. The existing ground had underlying stiff red clay of variable thickness over moderately weathered stone strata, which was unable to support the construction activity. It called for a foundation solution prior to the retaining structure construction with maximum height of 19m to level the site.
The TensarTech earth-retaining system composed of a TensarTech Green Slope and the SierraScape system. This was adopted for the construction of the plant’s retaining structures to meet the land use requirements. Meanwhile, the mechanically stabilised layer (MSL) incorporating Tensar InterAx geogrids were adopted to stabilise the soft ground, which effectively reduced differential settlement.
