Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To estimate the part filled with a grout in a sheath in a prestress concrete(PC) or the grout of a lock bolt and an earth anchor without destruction. SOLUTION: A grout is disposed in a prestress and a concrete member 1, a steel ball 4 is hit against edge part of a PC steel material 2 whose edge part is exposed and a shock acoustic wave is inputted, and an acoustic wave that is propagated in a PC steel material is detected by an acceleration meter 5. The edge part of the PC steel material and the arrival time of a reflection wave at the boundary between the filled part and the non-filled part of the grout are extracted, thus estimating the position of the non-filled part of the grout. Also, an acoustic wave is inputted as in the above, acceleration data detected by acceleration meters 5 and 5 are subjected to Fourier transformation to obtain a spectrum, and the non-filled part of the grout is estimated from the appearance/disappearance interval of a dominant frequency.  The above spectrum may be a response spectrum that is obtained by inputting a sinusoidal wave whose frequency changes to the PC steel material and detecting the response by an acceleration meter.
