Earth drill type enlarged base pile method that pursues environmental conservation and shortened construction period!

The "ECO-ACE Method" is a type of enlarged base pile method that allows for the entire excavation process, including the enlargement, to be carried out using the earth drill method. It can accommodate a maximum enlarged base diameter of 4.1m (construction diameter). It can be combined with the shaft excavation using three types of cast-in-place piles (earth drill, reverse, all casing). 【Features】 ■ Uses a Remo pump (mixing type slime removal pump) to extract slime ■ Improves the stable liquid to a sand content of less than 1% using a bentonite plant (sand separation device) equipped with a cyclone, ensuring reliable liquid replacement ■ Easy management of enlarged base excavation construction and reliable processing of the enlarged base *For more details, please download the PDF or feel free to contact us.
