Rehabilitation of all types of pipes, such as circular, rectangular, and horseshoe-shaped, as a strong composite pipe integrated with existing pipes and rehabilitation pipe backfill material, while maintaining non-excavation and water flow!
The existing pipe is fitted with rigid PVC material in a spiral manner while manufacturing the rehabilitation pipe, and a special backfill material is filled in the gap between the existing pipe and the rehabilitation pipe. This revitalizes the old pipeline into a strong composite pipe that integrates the existing pipe and the backfill material of the rehabilitation pipe.
【Features】
● The self-propelled pipe manufacturing method allows for the rehabilitation of various pipe shapes, including circular, rectangular, and horseshoe shapes.
● Construction can be carried out while allowing water flow, eliminating the need for temporary drainage within the main pipe.
● Non-excavation means there is minimal impact on traffic and social life.
● There are no restrictions on the pipe manufacturing distance, enabling long-distance pipe production.
● It can accommodate curved construction and can be installed with a slope.
● The flow capacity is equal to or greater than the design flow rate before rehabilitation.
● The rehabilitation pipe is excellent in durability, wear resistance, and chemical resistance.
● Seismic retrofitting of pipeline facilities is possible.
● Work can be suspended even during pipe manufacturing in the event of sudden heavy rainfall.
【Applications】
● Reconstruction and extension of the lifespan of aging or damaged sewer pipes (Ø250 to 5000)
● Strength restoration
● Improvement of water tightness against inflow, flowability, corrosion resistance, prevention of tree root intrusion, and seismic resistance enhancement
● Setting of pipe slope (rehabilitation pipe Ø800mm and above)
