Pre-boring pile method for civil engineering.
Our company handles the "COPITA Type Pre-Boring Pile Method." This method uses a drilling and mixing device with a diameter of the pile plus 100 mm, injecting drilling fluid into the ground as needed while excavating to the specified depth, and then injecting a solidifying liquid to create the solidified section. While raising the drilling and mixing device, we inject and mix the pile surrounding fixed liquid to create soil cement within the ground. After that, we install and embed precast concrete piles either by self-weight or rotary pressing to secure them in place. 【Features】 ■ Straight drilling without constructing an enlarged bulb at the tip ■ Collection of unconsolidated samples from the pile surrounding fixed section ■ Strengthened management of on-site welded joints ■ Thorough construction management *For more details, please download the PDF or contact us.
