Basic information about the TRD method and various construction examples are provided! Outstanding stability! Capable of constructing underground continuous walls at a maximum depth of 60 meters with a machine height of 10 meters!
The "TRD Method" is a construction technique that involves moving a cutter post installed underground laterally while excavating the ground with cutter bits attached to a cutter chain. During this process, a solidifying liquid is mixed and stirred with in-situ soil in a vertical direction to create a wall-like solidified body underground. 【Features】 1. Outstanding stability 2. High precision construction is possible 3. Cost savings achieved through excellent excavation capability 4. Homogeneous wall quality in the depth direction 5. Continuous structure without discrepancies 6. Arbitrary setting of core material spacing is possible *For more details, please 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.
