A mud density method suitable for soil conditions nationwide! We will take on even more challenging construction with our technology and track record!
The "SS Small Method," which has an overcutting function, rapidly mixes high-concentration mud water containing a large amount of excavated soil and clogging material sprayed onto the face in a chamber, creating a thick, high-concentration stable liquid. By pressurizing and filling the face and tail voids, this method achieves high stability of the face and is based on the concept of "stabilizing liquid methods" such as underground continuous soil retaining wall methods and reverse circulation methods.

basic information
【Features】 - By filling and pressurizing the tail void with high-concentration mud, the resistance value on the outer surface of the pipe is reduced, enabling long-distance propulsion. - Due to the favorable pressure balance provided by the high-concentration mud, the impact on the ground is extremely low compared to other construction methods. It can accommodate a wide range of soil types, from soft ground to boulder layers. - The discharge method utilizes the pressure difference and the fluidity of the high-concentration mud from the face to inside the machine, and from inside the machine to outside the tunnel, it transports the slurry using a vacuum suction device. - The standard machine can fully take in boulders and can handle sizes up to 1/3 of the nominal diameter. The boulder crushing type can accommodate boulders up to approximately 100% of the nominal diameter. - It is capable of ultra-sharp curve propulsion with a radius of about 15 meters. - Long-distance propulsion of approximately 500 meters can be achieved with just the thrust. - The compact propulsion equipment allows for construction in narrow temporary yards. - It requires almost no auxiliary methods except for starting and reaching the destination. - By adopting a segmented recovery and small shaft starting type, it enables construction in locations where large shaft construction is difficult and allows for reaching existing structures.

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.
