摘要： PURPOSE:To detect the abnormality of underground piping by exciting in terms of sound wave pipings buried in a burying body by a sound wave source installed in a branch pipe, and at the same time, irradiating microwave on the surface of the burying body near the place where the piping is buried. CONSTITUTION:A water leakage position detecting device 11 consists of an ultrasonic sound source installed mainly in the branch pipe 3 of a water pipe 1 and excites in terms of ultrasonic wave the water pipe 1 and water in the water pipe 1, a synchronizing signal detector 12, a microwave device 13 and a recorder 10. The ultrasonic wave sound source consists of a vibrator 6 and a vibrator driving device 7. The device 13 is provided movable near the ground surface, and irradiates microwave on the ground surface of the place where the water pipe 1 is buried, and at the same time, detects the reflected wave of the microwave modulated by feeble ultrasonic vibration of the ground surface propagated from the water pipe 1 through the ground 2. Thus, the presence of abnormality of the state of burying can be judged accurately.

摘要： PURPOSE:To detect the abnormality of underground piping by exciting in terms of sound wave pipings buried in the burying body by a sound wave source installed in a branch pipe, and at the same time, irradiating laser light on the surface of the burying body near a place where the piping is buried, and detecting its reflected light. CONSTITUTION:A water leakage position detecting device 11 consists of an ultrasonic wave sound source installed mainly in the branch pipe 3 of a water pipe and excites in terms of ultrasonic wave the water pipe 1 and water in the water pipe 1, a synchronizing signal detector 12, a laser light equipment 13 and a recorder 10. The ultrasonic wave sound source is made up of a vibrator 6 and a vibrator driving device 7. The equipment 13 is provided movably near the ground surface, and irradiates laser light on the ground surface near the place where the water pipe 1 is buried, and at the same time, detects the reflected light of the laser light modulated by feeble ultrasonic vibration of the ground surface propagated from the water pipe through the ground 2. Thus, the presence of abnormality of the state of burying can be judged accurately.
