Ground reinforcement work Σ-i method [Performance certification method]

Advanced pile-type ground reinforcement Σ-i method that has obtained architectural technical performance certification.

This is a highly reliable pile foundation reinforcement method for small-scale buildings, including residential structures. It features a new spiral-shaped tip wing integrated with four excavation blades at the tip, allowing it to penetrate the ground while rotating. The rotary insertion construction minimizes vibration and noise, and it establishes an environmentally friendly design that generates no excavated soil (residual soil) during construction. Furthermore, by adopting an improved tapered tip wing, it allows for the selection of several types of steel pipes for a single tip structure, successfully achieving dramatic cost reductions and economical design while maintaining high construction performance and safety.
