Sewage channel or pipe repair - using longitudinal carrier with carrier units to apply radial holding pressure on lining for inner side of channel

摘要

To insert an inner mantle material in sewage channels and pipes, an esp. longitudinal carrier (21) is supported at the inner side of the channel by guides (22) at both ends which also move it along. Variable radial carrier units (23) on the carrier (21) hold the inner mantle (17) in place through their radial tensioning force. Pref. the bonding and/or sealing material is a synthetic resin such as an epoxy resin or polyester resin, an adhesive, motor, concrete sludge etc.. USE/ADVANTAGE - The system is for lining sewage channels and pipes, where they have been damaged or have deteriorated. The operation gives a repair lining to the channel or pipe inner side, rapidly and easily, through remote control and with TV monitoring.
