ベル・ミクロ工法協会 List of Products and Services

The "Berliplace method" involves inserting a pilot crusher into an existing pipe, expanding and crushing the existing pipe while advancing with a tunneling machine that collects debris, and pushing in a new pipe (PVC pipe). The pilot crusher is equipped with crushing blades and a water-stopping device, allowing construction even under groundwater conditions. It contributes to the longevity of PVC pipes and reduces lifecycle costs. 【Features】 ■ Contributes to the lifecycle cost (LCC) and longevity of sewer pipes through the advantages of PVC pipes ■ Proven advancement rate of over 15m per day ■ Cost reduction achieved through increased tunneling speed ■ Capable of reaching the first manhole ■ Economical *For more details, please refer to the PDF document or feel free to contact us.

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.
