The tapping sound measurement device 10 continuously performs measurement work in the circumferential direction of the tunnel wall surface T (16 times in this embodiment), 1
After the measurement work in the circumferential direction is completed, the tapping sound diagnostic device 10 is moved in the tunnel axis direction by a pitch corresponding to the width of the divided measurement areas adjacent to the tunnel axis direction (for example, the width of R11 and R21). Then, the same work is repeated. In the following description, a bundle of divided measurement areas (for example, R11 to R116) in which the measurement work is performed when one measurement work in the circumferential direction is performed is referred to as a measurement line (in the present embodiment, four measurement lines are performed). 1 for each survey line
It is assumed that there are 6 divided measurement areas).

[Preparation work] First, the reference data storage means 4
In 6a, the tunnel form data is stored, and the size of the unit measurement area of the tap sound measuring device 10 to be used is input. Subsequently, the position measuring device 30 is installed at a predetermined position, and the tip surface portion of the tapping sound measuring device 10 corresponds to the first divided measurement area R11 (measurement starting point) and the fourth measuring line corresponding to the first measuring line. 16th division measurement area R416

Then, while the position measuring device 30 measures the position of the tapping sound measuring device 10, the tapping sound measuring device guiding means 47 is used to guide the tapping sound measuring device 10 to the first divided measurement region R11 (S1).

After the guidance is completed and the accurate positioning of the hammering sound measuring device 10 is completed (S2, S3), the hammering sound measuring device 10 is operated to measure the hammering sound. The measured tapping sound is sent to the measurement data receiving means 41 of the main body device 40, the state is discriminated by the diagnostic data creating means 43, and diagnostic data is created (S4). Then, the created diagnostic data is stored in the measurement data storage means 46b together with the data of the diagnostic time and the divided measurement area number, and is sent to the display chart creation means 44.

Here, the divided measurement area R11 for performing tapping sound measurement
However, it is judged what number of the first survey line corresponds (S5) (in this case, is the divided measurement area in which the tap sound is measured the first point of the first survey line?). In this example, since the divided measurement range R11 for performing tapping sound corresponds to the first,
By the same method as described above, the tapping sound measurement device 10 is guided to the second divided measurement area R12 of the first survey line (S8), and the tapping sound is measured (S2 to S4).

Is the measurement area R12 the first point of the first survey line? And the divided measurement area R12 for tapping measurement is the last point of the first survey line [first
Sixth point]? ).

In this example, since the division target region R12 is the second one, the first division measurement region R1 of the first survey line is
The first surface image is captured. The photographed surface image data is sent to the measurement data receiving means 41 and trimmed to an optimum state by the surface image data processing means 49,
After being cut into the size of the upper surface frame 25a, it is subjected to predetermined processing, stored in the measurement data storage means 46b together with the data of the diagnostic time and the divided measurement area number, and sent to the display chart creation means 44.

The surface image data sent to the display drawing creation means 44 is matched with the development drawing data by the development creation drawing creation means 44b on the basis of the boundary position data of the divided measurement area R11, and is superimposed on the corresponding portion. It is matched and the development photograph data is created. In addition, the diagnostic data of the divided measurement area R11 that has been transmitted previously is matched with the developed radiographic drawing data by the diagnostic result diagram creation unit 44c on the basis of the boundary position data of the divided measurement area R11.
It is superposed on the corresponding part. As a result, diagnostic result diagram data is created, and is displayed via the display diagram output means 45.
It is displayed on the display 52a (S7). The developed developed view data and the diagnostic result view data are stored in the display view data storage means 46c together with the creation time data and the divided measurement area number data.

After the series of processing is completed, the tapping sound measuring device 10 is guided to the third divided measurement area R12 of the first survey line by the same method as described above (S8) and the tapping sound measurement is performed. Then, the subsequent processing is performed (S2 to S7). After that,
The same processing is repeated, and when the divided measurement area Ri corresponds to the final measurement area (16th) divided measurement area R116 of the first survey line, the tapping sound measurement device 10 is previously measured by the measurement area data creating means 42. The surface image of the 16th divided measurement area R116 of the first survey line is captured by guiding to a predetermined virtual measurement reference point. The photographed surface image data is processed by the same method as described above, and then the diagnosis result is displayed (S6, S9).

Then, it is judged whether or not the next survey line exists (S10), and when the next survey line exists, the control means 48 and the tapping sound measuring device guiding means 47 cause the tapping sound measuring device 10 to move to the next. The same work as described above will be performed by guiding to the first divided measurement area R21 of the survey line (in this case, the second survey line).

After that, the same operation is repeated, and when the measurement of the surface image data of the final divided measurement area R416 of the final measurement line (in this case, the 16th measurement line of the fourth measurement line) is completed, the tapping sound diagnosis is performed. Will be completed.

Diagnosis is performed by creating drawing data, further superimposing the diagnostic data of each of the divided measurement areas Ri on the developed radiographic drawing data by matching with the boundary position data of the divided measurement area Ri as a reference, and outputting the data. Since we are creating a result diagram,
Furthermore, it is possible to make the system excellent in visibility.

Further, in the display diagram creating means 44, it is possible to create a diagnostic result diagram using only the developed view or a diagnostic result diagram using the developed photographed image in accordance with the operator's selection, and to display the diagnostic data. Since it is possible to display in various formats, it is possible to provide a system with excellent convenience.

Further, the position measuring device 30 can be used to measure the position of the tapping sound measuring device 10 and the position of the tapping sound measuring device 10 can be controlled using the tapping sound measuring device guiding means 47. Therefore, it is possible to guide the hammering sound measuring device 10 to a desired position by interlocking both devices. Therefore, since it is possible to perform the work of measuring tapping sound at an accurate measurement position, it is possible to more accurately display the tapping sound diagnosis result.

Further, since the measured tapping sound data can be stored in the measurement data storage means 46b, it is possible to compare the results of the tapping sound measurement diagnosis at the same point over time, which is excellent in convenience. The tap sound diagnosis result display system 1 can be provided.
