In the method, an eddy-current flaw detection is carried out for a test tube which is or is equivalent of the tubular object 100 and has a plurality of kinds of simulated defects previously disposed on its inner and outer surfaces 101, 102, while DC magnetizing the test tube by using the sensor, and then the intensity of above DC magnetization and a test frequency of the eddy-current flaw detection coil 12 are selected so that the simulated defects can be detected, and the simulated defects located on any of the inner and outer surfaces 101, 102 of the tubular object 100 can be identified, by using both effects of a magnetic permeability change and an occurrence of eddy current E, E', and then the sensor is inserted into the tubular object 100, and the eddy-current flaw detection is carried out, while DC magnetizing the tubular object 100 in the condition of the selected DC magnetization intensity and test frequency. Which one of the inner and outer surfaces 101, 102 of the tubular object 100 has the defect is identified by using a detection signal of the eddy-current flaw detection coil 12.

Abstract: PROBLEM TO BE SOLVED: To provide a cavity testing method of concrete construct which can test a cavity for its presence and degree by boring only a single hole into the cavity. SOLUTION: In this method, at first a hole is bored into the concrete construct 100. Through this hole 130, let a given amount of gas flow in or flow out (hereinafter called "inflow, etc.") by a predetermined pressure. The volume of a cavity 120 communicating with the hole 130 based on time variation in pressure ratio obtained as the quotient of measuring pressure divided by the predetermined pressure. Then, the pressure ratio per time variation is determined by using the pressure ratio in the time zone when the pressure ratio began to be reduced after rapid depression. COPYRIGHT: (C)2009,JPO&INPIT
