<P>PROBLEM TO BE SOLVED: To provide a conduit inspection device capable of automating inspection of a buried piping and suitable for miniaturization. <P>SOLUTION: A conduit inspection device comprises: position detecting means 7 for detecting the position of the device within a conduit; sound pressure detecting means 5 and water pressure detecting means 6 for detecting a sound pressure and a water pressure in the conduit; a branch determining circuit for determining a branch of a water stream based on a signal from the pressure detecting means; and control means 10 for controlling the position detecting means 7, the sound pressure detecting means 5, the water pressure detecting means 6, and the branch determining circuit. The control means 10 puts the sound pressure detecting means 5, the water pressure detecting means 6, and the position detecting means 7 into operation simultaneously while moving in the conduit to obtain information on a water leakage position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
