Soil-cement diaphragm wall method applicable to hard ground with N value of 100 or more.
The "CCC Method" is an abbreviation for the Chain Conveyor Cutter method, which uses CCC to construct ground improvement bodies. By mixing and blending the excavated ground with solidifying materials into soil cement, it enables the construction of underground continuous waterproof walls, temporary earth retaining walls, building foundations, grid-like improvements, and full improvements, among other applications, including soil contamination countermeasures. 【Features】 ■ The quality of the improved body is uniform in the vertical direction. ■ Capable of constructing gravel layers with an N value of 50 or more. ■ Immediate response is possible even if the depths differ within the same site. ■ Quick changeover of construction progress direction. ■ NETIS registration number QSK-12005-V. *For more details, please refer to the catalog or feel free to contact us.

Company information
Our company was founded in 1958 and specializes in underground special civil engineering works such as underground continuous walls, underground obstacle removal, ground improvement, and pipeline construction. In recent years, we have expanded our business operations to include slope work and construction. There is a growing social demand for securing the natural environment, seismic reinforcement, liquefaction prevention, restoration of structures, and urban redevelopment, which have become pressing issues in recent years. In response to these social needs, we have developed seismic reinforcement and liquefaction countermeasure methods such as the "Ultra Multi-Point DP Method" and the "High Grip Grout Method." For structural restoration, we utilize our in-house developed restoration method called "Suiheikun," and for urban redevelopment, we are conducting research and development of new methods such as the "Hiro Work Kmigty Method," "Bauer Method," and "Super Top Method," aimed at underground obstacle removal. Additionally, as part of our eco-friendly initiatives, we are researching and developing methods that use bubble drilling fluid to reduce industrial waste, striving to contribute to society through high-quality construction and services. We aim to continue responding to the needs of the times by deploying a variety of specialized techniques and uniquely developed methods.
