Basic Pile Foundation Method "CHR Method"

Piling construction is possible even in narrow tracks! Construction method suitable for low headroom and confined spaces.

The "CHR method" is an economical foundation pile construction method that excels in the installation of steel pipe piles under strict conditions, such as headroom restrictions below girders and constraints on work areas, which have made construction difficult. It is possible to install wing piles with a pile diameter of φ318.5 to 700 mm and a maximum wing diameter of 2.5 times the diameter (screw-type micro piles have pile diameters of φ216 mm and 267 mm) in low headroom and narrow spaces. With low vibration and low noise, and compliant with exhaust gas regulations (off-road law), this method minimizes noise, vibration, and environmental impact, making it suitable for construction in tight spaces. 【Features】 ■ Enables railway construction using wing piles ■ Achieves low vibration and low noise ■ Environmentally friendly construction without soil displacement ■ Introduction of a comprehensive construction management system *For more details, please download the PDF or feel free to contact us.
