Tsubasa pile (steel pipe rotary driven pile)

Achieving high tip support capacity! An environmentally friendly construction method with no soil disposal, low vibration, and low noise.

The "Tsubasa Pile (Steel Pipe Rotational Press-in Pile)" is a method that involves rotating a steel pipe pile equipped with semicircular steel plates (tip wings) at the tip, which are installed in a crossed manner, to penetrate the ground with low noise and low vibration. The tip wings are expanded to 1.75 to 2.5 times the pile diameter, contributing to a significant tip bearing capacity when functioning as a pile, and providing thrust to the pile during the rotational penetration process. There are two types of tip shapes: "closed-end type" and "open-end type." Inclined piles that can respond to horizontal forces are also possible. 【Features】 ■ Achieves large tip bearing capacity ■ Environmentally friendly construction method ■ Cost reduction ■ By using an enlarged head structure, it has horizontal resistance, excellent seismic performance, and reduced costs ■ Easy to remove *For more details, please refer to the PDF document or feel free to contact us.

basic information

【Other Features】 ■ Inclined piles that can withstand horizontal forces are also possible. ■ The diameter of the wings is 1.5 to 2 times the diameter of the steel pipe, allowing for significant support strength commensurate with the strength of the steel material. ■ As it is a no-excavation, low vibration, and low noise construction method, there is no environmental impact associated with the disposal of excess soil. ■ Due to the rotary insertion method, there is less noise and vibration, making it suitable for foundation work in urban areas. ■ There is no concern about contaminating groundwater as no cement milk is used during construction. ■ The no-excavation construction method reduces costs associated with the disposal of excess soil. ■ Insertion can be done in a clockwise direction, and extraction can be done in a counterclockwise direction. *For more details, please refer to the PDF document or feel free to contact us.
