Root Pile Method "SP Fix Pile Method"

A route pile construction method that achieves high speed, labor savings, and multi-stage hook effects.

The "SP Fix Pile" uses a hollow SP bolt as a center rod and employs the "Permanent Route Pile Method," which involves double-tube drilling with a general-purpose drill pipe, and can also be applied as a micro pile. Once drilling is complete, injection is performed through the SP bolt, and only the drill pipe is withdrawn, allowing for labor-saving and high-speed construction without the need for rod recovery or core material installation work. Although it features a thick bolt structure with a diameter of 115 mm or more, stable drilling and reliable shaping through pressurized injection can be achieved with a general-purpose anchor machine up to about 20 meters, making it effective as a long, thick bolt for countermeasures on slopes with extremely deep soft layers or embankment slopes. Additionally, when adopted as a compression-type pile foundation, placing a "mouth reinforcement pipe" at the head allows for the rational handling of horizontal forces and bending moments in addition to axial compressive forces. 【Features】 - Permanent Route Pile Method - Labor-saving and high-speed construction without rod recovery or core material installation work - Reliable shaping through stable drilling and pressurized injection - Rational handling of horizontal forces and bending moments in addition to axial compressive forces For more details, please contact us or download the catalog.

Reinforced soil method EP route pile method

The EP root pile method, which firmly establishes roots in the earth, realizes public works that harmonize with people and nature.

The EP root pile method is a reinforcement technique developed in Italy to prevent natural slopes and ground from collapsing. "Root pile" refers to tree roots, and it involves inserting numerous mortar piles, approximately 10 cm in diameter and reinforced with rebar, into the ground like tree roots to integrate the soil.

EP Route Pile Method

It has been widely adopted in the reconstruction projects of the Hanshin Awaji and the Great East Japan Earthquake!

The "EP Route Pile Method" is a ground reinforcement construction method that has been widely adopted since it was used in Japan in 1980 as a protective measure for an observation deck near a shield tunnel. The cement milk used as the injection material hardens and expands, enhancing not only the core material but also the friction with the soil, promoting integration with the ground. The mesh arrangement effect of the piles suppresses soil deformation and soil flow between the piles, achieving integration between the piles and the ground. 【Features】 ■ Enables downsizing of structures ■ Ensures traffic on existing roads during construction ■ Guarantees overall stability of the structure ■ Allows reinforcement while preserving existing structures ■ Can be implemented even in sloped areas or challenging ground conditions ■ Can be executed in narrow spaces *For more details, please download the PDF or feel free to contact us.
