<p>PURPOSE:To continuously perform a series of works, by applying inner surface repairing in a supply pipe at first and, thereafter, performing repairing due to the traction of a pig while performing an air-tightness test after repairing due to a penetrated resin. CONSTITUTION:At first, a resin lining layer is formed to the inner surface of a supply pipe 2 branched from a conduit 1 to perform a first inner surface repairing process. Next, pigs 6, 7 are introduced into the conduit 1 by the traction of a traction cable 8 to fill the conduit 1 with a primer C and a filling resin D to perform a second predetermined repairing process. At the time of this second process, because the resin D is penetrated into the branched mouth part of the supply pipe 2 to close the same, by the monitoring of a self-recording type manometer 92, it can be judged whether the supply pipe 2 is perfectly repaired. By this method, continuous repairing work is achieved.</p> |
