"PVC Pipe Long-Distance Curved Pushing Method" - The world's first pushing technology that contributes to reducing life cycle costs.
The Bell method is a "world-first system" that significantly reduces maintenance costs for sewer pipes and contributes to their longevity. 【Features】 1. Long-distance thrust Unlike conventional methods, the allowable thrust length is not limited by the pipe's allowable load capacity, allowing for long-distance thrust of up to 250 meters even with low-load capacity pipes. 2. Curved thrust The tunneling machine is equipped with two directional correction devices, enabling multiple curved thrusts of up to 60R. 3. Response to obstacles If unexpected obstacles are encountered during tunneling, it is possible to retreat and proceed with a detour alignment. 4. Shortened construction period By adopting an autonomous measurement robot for in-pipe surveying, there is no decrease in daily progress due to the number of curves or curvature radius. Additionally, using the Bell method thrust pipe (1.33m pipe) reduces setup changes by 33% compared to 1m pipes, enhancing work efficiency. 5. Longevity Long-distance and curved thrust is achieved with durable and earthquake-resistant PVC pipes, contributing to the longevity of sewer pipes. 6. Earthquake resistance High earthquake-resistant SUS color is used. The joint section of the thrust pipe maintains water tightness up to an angle of 3 degrees, preventing water and soil from entering.

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.
