SPR method

Pipeline renewal methods and systems
Product Features
- The SPR method rehabilitates (remodels and updates) worn pipes by injecting special backfill materials into the gaps of existing and rehabilitated pipes after crowning and manufacturing the pipes while winding bands of rigid vinyl chloride resin profiles with both ends crowned into a spiral within the existing pipes. Can be used with regard to such issues as the impact on traffic jams and structures without digging up the ground, thus also greatly reducing waste outflow. Further, the development of automated SPR method to strengthen workability and improve safety contributes to solving urban infrastructure problems.
