摘要： PURPOSE: To repair satisfactorily without wasting a resin by detecting the arrival of a resin-entraining air current, which is blown into a supply pipe, at a duct with a change of sound pressure levels, and stopping the supply of the resin.
CONSTITUTION: Low-pressure air is blown into a supply pipe 2 by operating a blower 52, and a resin is injected into the air current from a resin force feeder 55 to form a resin-entraining air current, which is forced into the supply pipe 2, toward the pipe end connected to a duct 1 and successively moved to form a lining layer in the pipe 2. In this series of repairing, operating sounds, generated in the supply pipe 2, are detected by a sound sensor 71 and recorded by a recorder 7 to record a change of sound pressure levels. When the resin-entraining air current reaches the pipe end connected to the duct 1, the vibration of the sound pressure level or the generation of interrupted sound due to the escape of the resin-entraining air current appear as a waveform change point. Consequently, the time to stop the supply of the resin is surely found by confirming said change point.

摘要： PURPOSE: To prevent waste of a resin and to dispense with aftertreatment by measuring variations of pressure in blowing a resin flow into a supply pipe, and detecting the arrival of the lining resin at a duct.
CONSTITUTION: A lining resin is blown as a fog into a supply pipe 2 by the operation of a blower 6, deposited on the inner wall of the pipe 2 to form a lining layer, and sent to the duct 1 side. In said process, the internal pressure of the pipe 2 is gradually increased by the injection of the lining resin. When the resin flow in the supply pipe 2 arrives at the junction of a duct 1, the leading part of the resin is spouted into the duct 1, and air runs away into the duct 1. Consequently, the internal pressure of the supply pipe 2 is decreased. Accordingly, the time when the internal pressure peaks is detected by a pressure gauge 10 as the time when the necessary amt. of the resin is supplied. The injection of the resin is stopped, and only the blower 6 is operated for specified hours. Repairs are carried out without wasting the resin in this way.
