In the track 1, a ballast B made of gravel or crushed stone is piled up on a roadbed (ground) 2 to form a ballast 3, on which sleepers 4 are arranged at predetermined intervals, and left and right rails 5L,
It is configured by fixing 5R. In this case, the sleepers 4 are buried in the ballast B to a standard depth to prevent movement,
In addition, the ballast B spreads the train load widely on the roadbed 2, improves drainage, and also acts as a spring.

されている。The above ballast B may collapse for some reason. The collapse of the ballast B first occurs on the shoulders on one side or both sides of the track bed 3, and this usually extends between the rails 5L and 5R in sequence. Figure 6
An example of a state in which the ballast B of the right shoulder portion 3R collapses is shown. As a result of the normal ballast B 1 collapsing, the ballast B 2 becomes a ballast B 2 and a collapsed portion D of depth H, width W, and length L Has occurred. However, the illustration is an example, and the cross-sectional shape and the spread range of the collapsed portion D vary in size. In any case, when the ballast B collapses, the above-mentioned actions such as the movement prevention of the sleepers 4 are lost and the function is not fulfilled, which hinders train operation or, in the worst case, becomes dangerous and inoperable. It is absolutely necessary to find and treat such a collapse as soon as possible. For this reason, when the inspector walks around to check the condition of the ballast B and finds the collapse part D,
Immediately repaired, each function of ballast B is always maintained well.

The sleepers are embedded in the ballast at a reference depth and arranged at a predetermined interval, and in the track constituted by fixing the left and right rails to the respective sleepers, each is mounted on a track inspection vehicle,
The projector includes a light projecting unit that projects a plurality of laser spots on a straight line in the track cross-sectional direction on the slopes of the ballasts on the left and right shoulders of the roadbed, and a TV camera that captures each laser spot at appropriate time intervals. Each of the TVs can be operated by the two sets of measuring optical system consisting of the light receiving section and the running of the track inspection vehicle.
Image data sequentially output by the camera, and the distance mark from the distance mark generation unit already installed in the track inspection vehicle,
And a recording unit composed of VTRs recorded in parallel and provided on the ground, analyzing each image data recorded in the VTRs, and the sectional shape of the ballast of the left and right shoulders at the time of each imaging. Then, the cross-sectional scale is calculated respectively, and when the calculated cross-sectional scale is larger than the preset reference value, the ballast state of the shoulder is determined to be defective, and the collapsed portion is detected, and the detection is performed. A ballast condition inspecting device for a shoulder of a roadbed, comprising: a ground device for adding position data obtained from the distance mark to the cross-sectional shape of the collapsed portion and displaying the data on a display.
