Achieving long-distance curved propulsion! Proposing a reduction in lifecycle costs through the longevity of sewer pipelines.
The "Bell Method" allows for long-distance pushing of up to 250 meters even with low-strength pipes, as it is not limited by the allowable thrust extension like conventional methods. By equipping the tunneling machine with two directional correction devices, it enables multiple curved thrusting up to 60R. If unexpected obstacles are encountered during tunneling, it can be retracted and tunneling can proceed along a detour alignment. Additionally, this method achieves long-distance and curved thrusting with PVC pipes, contributing to the longevity of sewer pipelines. 【Features】 ■ Long-distance thrusting and curved thrusting ■ Response to obstacles ■ Shortened construction period ■ Increased lifespan ■ Earthquake resistance *For more details, please refer to the PDF materials or feel free to contact us.
