摘要： PROBLEM TO BE SOLVED: To suck infiltrated water in a pipe, and to detect surely and efficiently a leak spot where the water infiltrates. SOLUTION: An inspection inner pipe 3 is inserted into a gas pipe, and while moving the inspection inner pipe 3, an image in a pipe photographed by a camera 15 is checked by a camera monitor 38. When confirming the infiltration of the water in the pipe 5-1, the water is sucked by an infiltrated water sucking hose 36. After sucking the water, an airtightness test in the peripheral part is performed, to thereby detect the leak spot where the water infiltrates. A balloon 17 for airtightness is expanded on the spot where the inspection inner pipe 3 is inserted into a prescribed position, and an airtightness test section is set up, and a gas such as the air or a gaseous body is enclosed in the test section and pressurized, and the leak spot is specified by pressure measurement of the enclosed gas or by leak sound detection of the gas by microphones 25-1, 25-2.

摘要： PROBLEM TO BE SOLVED: To prevent a damage from being detected wrong by A/D converting time series data of a receiving voltage, process the data by a method of moving average and comparing values between a present time point and a preceding time point. SOLUTION: An unprocessed data of a receiving voltage when a damage simulation signal is applied at a time point t2 to a buried pipe where a noise current of a high frequency runs is as shown by (a). The receiving voltage decreases large after the time point t2 , and suddenly drops once at a time point t1 by pulse noises. The unprocessed data of (a) is processed by a method of moving average with a rectangular weighing function, whereby a data of (c) is obtained with noises of the high frequency removed. A decrease width at the time point T1 is reduced. When the receiving voltages of adjacent sampling time points are sequentially processed/compared, a data of (d) is obtained and peaks at the time points t1 , t2 are turned small. Noises of the high frequency are nearly eliminated. A data of (e) is obtained by processing the unprocessed data by the method of moving average with a triangular weighing function, wherein the dullness of a wavelength at the time points t1 , t2 is improved. A damage can be distinguished and detected in this manner separately from the pulse- like decrease of the voltage.

摘要： PURPOSE:To prevent a buried pipe from being damaged by the cutter of a drilling machine. CONSTITUTION:A band body 13 is arranged with wires 14 at an appropriate interval such that the wires 14 are conducted in the longitudinal direction of the band body 13 to constitute a long monitoring body 12 which is then buried in the vicinity of an object to be monitored, i.e., a buried pipe 11. A resonance characteristics measuring apparatus 16 for the wire 14 is disposed on one end side of the long monitoring body 12 and an AC monitoring signal is inputted while sweeping the wire 14 from one end side thereof thus measuring the resonance frequency of the wire 14 and monitoring the cut-off of the wire 14 due to damage of the long monitoring body 12 based on a resonance frequency. Since a damage alarm signal of the buried pipe 11 can be delivered at a moment when the cutter of a drilling machine approaches the buried pipe 11, the buried pipe 11 can be protected against damage.

摘要： PURPOSE:To accurately calculate an actual dimension from an image dimension with respect to flaw height by making the corresponding relation between the image dimension and the actual dimension approximate by the fold line due to a plurality of regression line formulae. CONSTITUTION:A part of a predetermined echo level or more is displayed as the image of a flaw and the corresponding relation of flaw height with an image dimension is made approximate using estimation formula H=a.b+b (wherein H is an actual dimension, h is an image dimension and a and b are a constant) to calculate an actual dimension. In this method, the corresponding relation between the image dimension and the actual dimension is made approximate by the fold line due to a plurality of regression line formulae. That is, the actual dimension 0-8mm of flaw height is divided into four stages at an equal interval of 2mm and, corresponding to the respective stages, the corresponding relation between the image dimension and actual dimension of flaw height is made approximate by a plurality of regression line formulae (1), (2), (3), (4) as shown by solid lines. The number of regression line formulae can be appropriately determined. Contrarily, a regression line formula may be calculated at every equal interval of an image dimension to perform approximation.
