Bell method
"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.
