Dawn Construction Method

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.

Ground Improvement

Ground Improvement

Column improvement and surface improvement! The targets are weak clayey or sandy ground, etc.

"Ground improvement" involves artificially enhancing the properties of the ground or soil. The targets for improvement include weak clayey or sandy ground, unstable rock formations, and permeable rock formations. In "columnar improvement," cement-based solidifying materials are injected to a stable ground level, creating columnar bodies within the soil. In "surface improvement," cement-based solidifying materials are spread over relatively shallow weak ground, and the strength of the ground is increased through mixing, stirring, and compaction. 【Details】 ■ Columnar Improvement ■ Surface Improvement *For more information, please refer to the PDF document or feel free to contact us.

Ground improvement work "Tenokoram Method"

Ground improvement work "Tenokoram Method"

The Tenokoram method can solidify weak ground and improve it into high-quality ground!

The "Tenokoramu Method" is a technique that solidifies the ground into column shapes using solidifying materials. We confirm the "improvement system" for all soil types, including loam and organic soil, and by introducing a construction system that allows real-time management of our self-developed construction conditions, we have successfully enhanced the reliability of underground construction that is not visible to the public, gaining strong trust from our users. This method is mainly used for foundation ground improvement of buildings, with a vast track record ranging from single-family homes and apartment buildings to large shopping centers and skyscrapers. 【Features】 ■ It is possible to create high-quality, high-strength columns that are not found in conventional ground improvement methods through mixing and construction management. ■ Mechanization significantly reduces dangerous work, allowing for safer operations. ■ Improvement effects can be obtained early. ■ The construction process is simple, allowing for significant reductions in construction time and enabling economical design. ■ It is not limited by soil type; it can be applied to sandy soils as well as highly cohesive clay and loam. ■ It is also compatible with peat. *For more details, please download the PDF or feel free to contact us.

"Shiga Prefecture Ground Improvement" Ground Reinforcement Method 'Woody Force Method'

"Shiga Prefecture Ground Improvement" Ground Reinforcement Method 'Woody Force Method'

Applicable to sandy and clayey soil in Shiga Prefecture! This is an ecological and environmentally friendly method that utilizes small-diameter thinned wood as ground reinforcement material for housing!

The Woody Force method is a ground reinforcement technique aimed at small-scale buildings, utilizing unused thinned timber. This method uses thin-diameter thinned timber of "sugi" (Japanese cedar) or "hinoki" (Japanese cypress), which is somewhat too slender for use as house pillars and has been largely underutilized, as ground reinforcement material for houses, making it eco-friendly. By applying anti-corrosion and anti-termite treatment that complies with AQ certification (certification for quality wood building materials, etc.) B-3 (outdoor product components) to the wood used as ground reinforcement material, we aim to further enhance durability. 【Features】 ■ CO2 Reduction - Does not use cement or steel, which emit large amounts of CO2 during the manufacturing process - Contributes to energy conservation and reduction of greenhouse gases ■ Durability - By applying anti-corrosion and anti-termite treatment that complies with AQ certification B-3 to the wood used as ground reinforcement material, we aim to further enhance durability. *For more details, please refer to the PDF document or feel free to contact us.
