The "CSM method" is a construction technique that uses a horizontal multi-axis rotating cutter to mix soil and a cement-based slurry in place, creating rectangular soil-cement walls (such as retaining walls and waterproof walls) and ground improvement structures. It leverages the performance of the horizontal multi-axis rotating cutter, which has a proven track record in the excavation of stabilized liquid for underground continuous walls, providing high excavation capability that allows for construction even in hard ground without auxiliary methods. Additionally, it can be constructed with uniform wall thickness, offering flexibility in setting the spacing of the necessary inserted core materials to respond to generated stresses. 【Features】 ■ High excavation performance and precision ■ Efficient construction management system ■ Low noise and vibration ■ Customizable core material spacing ■ Compact machinery capable of deep construction *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The "V-JET Method" is a high-pressure injection mixing technique that cuts the ground using ultra-high-pressure spraying of cement-based hardening materials, rapidly creating cylindrical improved bodies. A special dedicated monitor with a step-facing injection mechanism enables efficient cutting, achieving larger diameters for the improved bodies and faster construction. We offer four types based on the amount of hardening material injected and the machinery used. 【Features】 ■ Rapid construction of large-diameter improved bodies ■ Wide range of diameters for improved body construction ■ Adoption of direct drilling method ■ Reduction of mud generation due to improved injection mixing efficiency ■ Applicable for ground liquefaction countermeasures *For more details, please refer to the PDF document or feel free to contact us.

• Ground improvement

The "WILL Method (Slurry Oscillation Mixing Method)" is a construction technique that injects slurry-like solidifying agents and improvement materials through a special mixing blade attached to the tip of a backhoe-type base machine, forcibly mixing the solidifying agents with the in-situ soil to form a stable improved body. By using two types of response screw-type mixing blades, it can accommodate not only weak, viscous soil layers but also compact sandy soil and gravel layers with an N value exceeding 30. Additionally, by selecting the appropriate base machine, it can handle medium-depth improvements of up to approximately 13 meters. 【Features】 ■ Construction of high-quality improved bodies ■ High excavation performance ■ Reduced environmental impact ■ High mobility and safety ■ Reliable quality control *For more details, please refer to the PDF document or feel free to contact us.

• Ground improvement

The BG method involves equipping a base machine with a leader and a high-torque rotary drive, allowing for the execution of all-casing foundation pile work, underground obstacle removal work, and stable liquid drilling foundation pile work using a Kelly bar. The underground obstacle removal work involves rotating and pressing in a casing tube while excavating and removing underground obstacles using drilling tools (auger drill, core tube, drilling bucket) and backfilling with quality soil. 【Features】 ■ Multipurpose drilling machine ■ Can be constructed in close proximity at boundaries *For more details, please download the PDF or feel free to contact us.

• Ground foundation construction method

The "DCS Method" is a cement-based deep mixing ground improvement construction system that creates DCS columns (soil cement columns). By injecting a solidifying agent (cement-based slurry) into the ground and mixing the soil, DCS columns (soil cement columns) are formed. The solidifying agent discharged from the DCS mixing blades (frame-type composite relative mixing blades) is effectively mixed and stirred with various soils, resulting in DCS columns that maintain excellent quality. 【Features】 ■ Large diameter columns of Φ2,000mm ■ Capable of reaching depths of up to 50m ■ Excellent mixing power through relative mixing ■ Outstanding capability to handle hard ground *For more details, please download the PDF or feel free to contact us.
