A construction method using a compact propulsion device that enables highly efficient excavation!
At Kinki Development Co., Ltd., we handle the "CBM Method," which is constructed using a small-sized thrust machine developed for horizontal boring (double casing method) from a launch shaft of 2,000mm to 4,000mm. The construction range is smaller, allowing for cutter head replacement during excavation (casing return type). Therefore, it can accommodate various soil types and obstacles. 【Features】 ■ Adopts horizontal boring method (double casing method) ■ Uses a small-sized thrust machine for construction ■ Smaller construction range ■ Cutter head replacement during excavation (casing return type) is possible ■ Capable of handling various soil types and obstacles *For more details, please refer to the catalog or feel free to contact us.
