Re-driving of piles is possible! It can be easily accommodated even in cases with time constraints such as close proximity construction or night work.
The "NS Eco Spiral" is a rotary-driven steel pipe pile that inherits the features of the "Small Diameter NS Eco Pile Method," which accommodates construction without soil displacement and in narrow spaces, while enhancing lateral support performance. By using a compact pile driver to directly screw a steel pipe pile with a wide range of spiral fins into the ground, the fins and the ground behave as a single unit, demonstrating significant lateral support strength. Therefore, when the support layer is deep or unclear, there is no need to unnecessarily extend the pile length. 【Features】 ■ Contributes to shortening construction time ■ Can be removed like a screw by rotating the pile in reverse ■ Compact construction ■ Easy to accommodate even when pile locations are scattered ■ Construction can be paused at any time *For more details, please refer to the PDF materials or feel free to contact us.

basic information
Conditions where this construction method is particularly effective: - Sufficient bearing capacity can be secured with an N value of around 5 to 10. - There are strata with an N value of around 5 to 10 at a depth of 20 meters or shallower, and there are no bearing layers with an N value of 30 or higher. - The diameter of the pile is determined by extraction or bending. *For more details, please refer to the PDF document or feel free to contact us.

Applications/Examples of results
【In response to such requests】 ■ We want to support lightweight equipment, but there is no clear support layer. ■ We want to resist pull-out loads, but we want to keep the pile length short. ■ We want to ensure the removal of the foundation of temporary structures after the construction is completed. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Futaba Materials Co., Ltd. is developing its business with two main pillars: the construction sector and the welfare services sector. We offer various construction methods, including the "SY Method," which allows for the installation of enlarged piles with five times the support capacity even in narrow sites using a mechanical widening bucket, and the "GSB Method," which enables the construction of enlarged piles in soft and medium-hard rock support layers using an all-casing approach. Please feel free to contact us if you have any inquiries.
