DRAINPIPE EASILY DETECTING WATER LEAKAGE

摘要

PURPOSE: A drainpipe easily detecting water leakage is provided to reduce the repairing costs of the drainpipe by precisely detecting the position of the drainpipe having water leakage. CONSTITUTION: In a drainpipe including a profile(19), wires(11a,11b) are installed at the outer surfaces of both wall of the profile. A bonding layer(150) is made of a nonconducting substance, and is installed between the outer surfaces of the profiles.
