Ground improvement work ☆ Deep mixing method 'T-column method' * Certification obtained

Ground improvement work ☆ Deep mixing method 'T-column method' * Certification obtained

This is a columnar improvement work of deep mixing treatment made possible by a self-developed stirring device (patent obtained) that enables high quality, low cost, and flexible responsiveness!

The T-column method is a construction technique that involves excavating the ground while injecting cement-based solidifying materials, efficiently mixing and stirring the solidifying materials with the soil using a uniquely developed mixing device, thereby constructing stable, high-quality columns (columnar improved bodies). ■ Japan Building Center Foundation Construction Technology Examination Certification (Building Technology) 　BCJ - Examination Certification - 219 ■ NETIS Number KT-150083-A <Features> - Maximum column diameter of 1.60 m and maximum depth of 16 m. It is possible to construct up to the maximum column diameter with a base machine of 0.7 m³ class without using a three-point pile driver. It can accommodate various types of soil, including cohesive soil, sandy soil, and loam, allowing for flexible responses to various road and neighboring conditions. - By using a fully automated plant, the slurry production process can be managed, ensuring stable quality. - In the case of small-scale buildings, a mold core can be created by sampling with a depth mold sampler. There is no need to collect boring cores, which can reduce construction time and costs. *Documents can be downloaded from the related links.
