があつた。[Problems to be solved by the invention] In measuring the trajectory curve using the conventional method described above, most of the inner upper surface of the outer rail is worn out, and it is difficult to manually measure every other thread 1. Since it is stretched between points M, a predetermined depth position D inside the outer rail 2
Although there is a measuring point M at , there are individual differences depending on the person who stretched the thread 1, and
Errors may occur because the measurement points M to which the scales are applied do not match exactly, and because the scale is also a normal scale, even if the same person measures the masaya at the same measurement point M, there may be errors at the time of measurement. There was a problem that it was not preferable as a measurement method in Masaya measurement, where relatively high measurement accuracy is required, such as the occurrence of errors in each measurement.

要するという問題点もあつた。 In addition, when measuring Masaya Check, for example, track curve surveying in places where it is difficult to install standard piles 3, such as existing slab track sections, non-track bed bridge sections, directly connected track sections, etc., and economically standard in quiet areas. In the past, standard piles 3 were installed in most sections, such as when measuring track curves in sections where piles 3 were not needed, or when repairing a track in an emergency. Not only is it difficult to perform accurate and economical emergency surveys, but it is also difficult to perform accurate and economical emergency surveys. In roadbed work that requires large machinery, there are cases where the reference pile 3 is removed and the work is carried out, and there is also the problem that the work to restore the reference pile 3 requires a great deal of effort.

ものである。[Means for Solving the Problems] In order to achieve the above object, the present invention has a positive arrow measurement scale on the surface on the plus side (outside the outer rail) and the minus side (outside the inner rail) with the O point in between. A pair of movement scales, which are provided on the back side with abutting claws that coincide with the O point position on the front surface and abut against each other at a predetermined depth position from the upper surface of the outer rail, and a pair of movement scales similar to this movement scale. The present invention is characterized in that it consists of a masaya shaku, which is movable in the direction of the masaya measurement scale, and is provided with a free shaku having a masaya check measurement scale.

The mating claws collide and are placed on the outer rail, and the mating claws on the lower surface of the Masaya shaku collide with each other at the above-mentioned center measurement point and are placed on the outer rail in the same way as the displacement scale. As a result, the O position of the movement scale and the positive arrow scale will always be located at the correct position of the measuring point, regardless of whether the rail is worn. After the thread is stretched at the O point position of the masaya measurement scale on both movement scales, read the masaya measurement scale on the masaya scale at the position where this thread and the masaya measurement scale of the masaya scale overlap. By doing this, the masaya can be measured in the field.

If the amount of movement at the second measurement point is S ₂ and the amount of movement at the third measurement point is -S ₃ , one end of the thread is placed at the S ₁ position on the positive arrow measurement scale of the movement scale mounted at the first measurement point. Align the other end of the thread with the _S3 position on the positive arrow measurement scale of the movement scale mounted at the third measurement point, and tension the thread. On the other hand, for the Masaya shaku mounted at the second measuring point, the S ₁ of the Masaya check measurement scale is set to S ₂ of the Masaya check measurement scale.
After sliding the free length so that it is aligned with the position, the rod is placed on the second measuring point with its abutting claws abutting each other. At this time, read the numerical value at the position where the previously stretched thread and the Masaya check measurement scale of the Masaya shaku overlap. If this numerical value is, for example, a, and the value of the straight square arrow at the second measurement point is also a, it is confirmed that the test value is correct. In this way, the positive arrow at each measurement point is checked in sequence.

At this time, read the numerical value at the position where the previously stretched thread 1 and the Masaya check measurement scale 9b of Masaya shaku B overlap. If this value is, for example, 30 mm, and the fairing arrow F at the second measurement point _M2 is also 30 mm, it is confirmed that the inspection value is correct. In this way, each station M ₁ ...

When checking the Masaya, it is possible to always correctly position the O position of the string and measuring device at the predetermined measurement point, which not only improves measurement accuracy, but also enables easy installation of reference stakes even in places where it is difficult to install. By using this measuring instrument, it is possible to accurately measure track curves without relying on reference piles, and it is ideal for use when surveying to make economical and emergency corrections to track curves.

Moreover, it is easy to place the rack almost perpendicularly to the outer rail, and in the case where the free scale of the Masaya shaku is provided with a knob that also serves as a set screw for the free scale, the free scale can be mounted almost perpendicularly to the outer rail. It has the effect of being able to securely fix the shaku in a predetermined position and preventing the shaku from erroneously moving during handling.
