Low cost, short delivery time, low noise! A mega-solar foundation method that accommodates all ground conditions!
The "Screw Press Steel Pipe Insertion Method" is a foundation method for mega-solar installations that adapts to all types of land. By performing pre-drilling, it enables construction on sandy soils, clayey soils, and gravelly ground. Additionally, since thick steel pipes are erected vertically, braces are unnecessary, allowing for wider spacing between piles and achieving overall cost reduction for the framework. During removal, the steel pipes can be sold for more than the removal costs, providing an advantage in asset value compared to methods that incur removal and waste disposal costs, such as concrete gravity foundations or concrete piles. 【Features】 ■ Foundation method using winged steel pipe rotary insertion ■ Asset value exceeding removal costs ■ Adaptable to various ground conditions ■ Achieves cost reduction ■ High quality, high precision, low noise *For more details, please refer to the PDF materials or feel free to contact us.
