This is a hydraulic full-rotation prefabricated pile excavation method developed for efficient construction of prefabricated piles (steel pipe piles and concrete piles) under harsh conditions such as low spaces and narrow sites. The dedicated machine directly grips the pile body and performs rotary insertion, while low-pressure cement milk is ejected to ensure the construction of a solid foundation bulb. ■ Space-saving: Weighing 5.1 tons or more, the compact machine with a maximum size of 2.8×2.2×2.0m can be easily transported to the excavation bottom. ■ Cost reduction: Eliminates the need for a leader, improving head loss and simplifying temporary facilities such as piers. ■ Improved construction efficiency: Self-propelled movement by the traction unit speeds up pile-to-pile movement in narrow sites. ■ Wide adaptability: Compatible with various diameters of steel pipe and PHC piles, capable of standard installation lengths of up to 50m. ■ Proven track record: Holds extensive construction data with 535 sites nationwide and a total construction length of 259,142m. *For more details, please download the PDF or feel free to contact us.

The "SPACE21 Method" is a hydraulic full-rotation prefabricated pile excavation method developed for efficiently installing prefabricated piles (steel pipe piles and concrete piles) under conditions such as low spaces and narrow locations. Since it does not require a leader for conventional pile drivers, it significantly improves headroom loss and is highly effective for short-length splicing pile installation in low spaces. As of December 2023, there have already been over 520 construction achievements, including those for public institutions. 【Features】 ■ Significantly improved workability in low spaces ■ Advantageous for construction in narrow yards ■ Easily movable and can be brought to underground excavation bottoms ■ Low vibration and low noise construction ■ Capable of various close-proximity construction, etc. *For more details, please download the PDF or feel free to contact us.
