[Construction Example] Pile Extraction (All Casing)

Introduction of case studies for all-casing pile extraction, including prefabricated piles and cast-in-place piles!

We would like to introduce a case study of our company's "Pile Extraction (All Casing)" construction method. First, we use an excavator to expose the top of the pile, and then we align the casing screw attached to the heavy machinery with the position of the buried pile and cover it with the casing. While rotating, we excavate down to the tip of the pile, perform the cutting of the pile edge, and confirm that the pile is rotating through the discharge outlet of the casing. Once the edge cutting is completed, the friction is eliminated, and the pile rotation stops. After that, we set a lifting wire at the tip of the buried pile and extract it with a crane. 【Construction Examples】 ■ Extraction of prefabricated piles ■ Extraction of cast-in-place piles (Nagoya City, φ1500 L=47.0m) *For more details, please refer to the related links page or feel free to contact us.
