In-house developed construction method 'Hatwing Method'

General Incorporated Foundation Japan Building Research Institute GBRC Performance Certification No. 15-17

In the "Hatwing Method," a specially processed tip wing is attached to the end of a copper pipe, which is then rotated and driven into the ground, utilizing it as ground reinforcement material. By having the tip wing shaped as a concave, soil can also accumulate in the concave part, effectively increasing the contact area with the ground and ensuring reliable support capacity. 【Features】 ■ The diameter of the tip wing is five times that of the axial copper pipe, demonstrating high support capacity even with low N values. ■ Any construction machine that can perform the work reliably is acceptable. ■ In addition to conventional stop management methods, design length management is possible. ■ An astonishing cost performance with diverse combinations of axial copper pipe and tip wing diameters. ■ Environmentally friendly and cost-effective. *For more details, please download the PDF or feel free to contact us.
