Dawn Construction Method

The birth of a savior for narrow site construction! A steel pipe pile method born from a thorough examination of the roles of blades and shafts.

The "Akatsuki Method" involves attaching a spiral wing steel plate to the upper part of a tip steel pipe, joining an axial steel pipe as a reinforcement material, and using a pile driver equipped with a rotary penetration device to rotate and penetrate it into the ground, utilizing it as ground reinforcement material. The tip of the reinforcement material, which receives significant ground reaction force, can be expanded as a wing section, and a main axial steel pipe with a smaller diameter than the tip steel pipe can be selected. Construction is possible not only with leader machines and pile driving vehicles but also, depending on the conditions, with an excavator. 【Application Range】 ■ Maximum construction depth: 10m (if soft layers continue and SWS is possible, up to 130D) ■ Applicable ground (tip ground): sandy soil (including gravelly soil), clayey soil ■ Applicable structures: - Buildings (3 stories or less, up to 13m in height, and a total floor area of 1500m2 or less) - Structures (retaining walls up to 3.5m in height, septic tanks, etc.) *For more details, please refer to the PDF materials or feel free to contact us.
