Construction is possible up to 80m! It is a low noise, low vibration method.
The "STJ Method" is a construction method for precast concrete piles that falls under the category of low-noise and low-vibration methods for the middle excavation and enlarged root solidification. By switching the auger's rotation to a low speed and jetting cement milk from high-pressure injection nozzles in two directions while raising the auger at a constant speed, a reliable enlarged bulb is constructed. 【Features】 ■ Reliable construction of enlarged bulbs ■ High bearing capacity ■ Rapid construction ■ Low construction costs ■ Low earth discharge method *For more details, please download the PDF or feel free to contact us.
