Exhibits outstanding water tightness! Capable of restoration beyond that of new pipes, making it suitable for measures against aging sewer pipes and agricultural water pipes.
The "SPR method" is a rehabilitation method that uses a self-propelled pipe manufacturing machine to create a PVC rehabilitation pipe inside an existing pipe. It can be completed quickly without the need for excavation while maintaining water flow. Additionally, it forms a continuous pipe without joints, demonstrating excellent water tightness. It can restore strength beyond that of new pipes, making it suitable for addressing aging pipelines such as sewer pipes and agricultural water pipes. 【Features】 ■ Can be constructed without digging up the road ■ Construction is possible while maintaining water flow ■ Self-propelled system accommodates long-distance and curved construction ■ Enables seismic retrofitting of pipeline facilities *For more details, please refer to the PDF materials or feel free to contact us.
