Abstract

A repair procedure for defective joints in inaccessible underground water pipes is described. Two access/services manholes are required (one either side of the defect) and a small trolley within the pipe on which is mounted a) a television camera and light, and b) a motor driven operating head. After inspection by closed circuit T.V. a set of brushes in inserted in the head to clean the repair area. A centrifugal projector then replaces the brushes and is connected by flexible line to a mortar supply vehicle. The repair operation is monitored inside a mobile control laboratory. An air current induced between the access holes prevents mortar spattering the camera and light.
