"Tsuitaro" is a mechanical joint that eliminates on-site welding of piles. After fitting the inner joint, which is welded at the factory to the lower end of the upper pile, onto the outer joint, which is welded at the factory to the upper end of the lower pile, a pin is inserted to join them together. To prevent the pin from moving or falling out during construction, a pin fixing screw is used to secure the pin. 【Features】 ■ No need for welding work on-site, allowing for easy connections ■ High strength and reliability ■ Simple construction management ■ Compatible with a wide range of pile diameters ■ Removable *For more details, please refer to the PDF document or feel free to contact us.

The "Screw Pile CK-EAZET" is a product with a simple shape that has a single spiral blade at its tip. For each pile diameter, the tip blade can be selected from multiple sizes. This allows for an economical design tailored to the ground and the building. Additionally, due to the rotary insertion method, there is no soil displacement associated with pile installation, eliminating the need for disposal of excess soil as industrial waste. Since no water or cement is used, clean installation is possible without contaminating the construction site. 【Features】 ■ Abundant pile specifications ■ Certification for clayey ground ■ Evaluation of pull-out bearing capacity ■ Environmentally friendly construction method ■ Compatible with pile pull-out work *For more details, please refer to the PDF document or feel free to contact us.

The "Anchor Wing Method" is a technique for preventing manhole uplift. By rotating and embedding an anchor section with spiral wings connected to rods into a stratum that poses no risk of liquefaction, and linking the rods to fixed fittings installed on the manhole head, the uplift of the manhole is physically and reliably restrained. This is a maintenance-free technology that requires no inspection, cleaning, or repairs to maintain drainage functionality over an extended period. 【Construction Flow】 ■ Removal of pavement and subgrade, excavation ■ Anchor wing set ■ Rotational embedding ■ Casing extraction *For more details, please refer to the PDF document or feel free to contact us.

• Civil Engineering Method

The "T-Wing Pile" is a pile that enhances load-bearing performance through the effect of multiple wings by arranging four spiral wings on a small-diameter steel pipe, while maintaining the construction advantages of an environmentally friendly method. Steel pipes are available in various diameters and wall thicknesses, allowing for the selection of suitable specifications according to design and construction conditions. Please feel free to contact us if you have any inquiries. 【Features】 ■ Completely no soil displacement construction, requiring no auxiliary materials such as water or cement ■ Minimal impact on the surrounding environment and safety due to the use of a compact specialized machine ■ Easy construction management by continuously measuring the penetration torque during construction ■ Capable of handling relatively loose ground, improving construction efficiency ■ The ground strength of the four wings and the base plate can be combined, resulting in high load-bearing efficiency and cost-effectiveness *For more details, please refer to the PDF materials or feel free to contact us.

The "K-Wing Z Pile" is a unique multi-winged steel pipe pile with an open tip, designed to protrude from the wing installation position. By using a two-wing pile with an open tip, the construction performance is enhanced, allowing for penetration into supporting ground that includes intermediate hard strata with gravel and cobbles. Sand and gravel soils can be selected as the supporting layer at the pile tip. 【Features】 ■ Low noise and no soil displacement, ensuring dry construction without contaminating soil or groundwater ■ The protruding opening under the wings reduces core misalignment caused by pile rotation ■ The two enlarged wings provide significant bearing capacity and pull-out resistance ■ By using the pile head as a magnifying glass, an economical design suitable for horizontal resistance and vertical forces is possible ■ Automatic recording of pile depth and rotation torque allows for comparison with the N value of the columnar diagram *For more details, please refer to the PDF document or feel free to contact us.
