本発明は、帯状に延びる湾曲面を検測するため

つた。[Prior art] For example, an automobile test course, a velodrome, an embankment,
Traditionally, a box hoe or bulldozer was used to construct curved surfaces such as waterways, but with this conventional technology, the accuracy of the finish and the amount of work per hour were largely influenced by the skill of the operator. . In particular, shaping work for automobile test courses requires careful work by skilled operators, as the work has a special three-dimensional curved surface and requires high precision. This resulted in extremely low work efficiency, long construction times, and high costs.

築されているか否かを検測しなければならない
が、通常テストコース等の３次元曲面はその帯状
の長手方向の各位置によつて湾曲の曲率がすべて

困難であつた。 In addition, it is necessary to inspect whether the shaped curved surface is constructed correctly according to the design value, but the curvature of the three-dimensional curved surface such as a test course usually depends on each position in the longitudinal direction of the strip. Since all of them are different, it has been extremely difficult to accurately measure them.

りに正確に検測を行うことは困難である。 Generally, in order to pave slopes, it is known that rails of a certain length are connected with pins, and a hydraulic cylinder is provided for each rail to bend it. In the case of a special three-dimensional curved surface such as a course, it is difficult to accurately measure the design values.

る。 However, since the device disclosed in Japanese Utility Model Publication No. 53-12208 measures a predetermined location on the human body, it is very small and the measurement work is all done manually, so it can be used on automobile test courses, velodromes, embankments, etc. It is impossible to apply when constructing curved surfaces such as waterways. Also, Utility Application No. 96125 (1972)
The microfilm device No. 43763) is for measuring liner holes in cylinder blocks, etc., and is applicable to curve measurements when constructing curved surfaces such as automobile test courses, velodromes, embankments, and waterways. I can't do it. Both methods do not have a control mechanism and are measured manually by the measurer, but they are useful for measuring curves when constructing curved surfaces such as automobile test courses, velodromes, embankments, and waterways. There is a problem in that doing everything manually requires a lot of labor and is not suitable for the actual situation in the civil engineering and construction industries, where the problem of labor shortages is particularly evident.

As a result, the flexible ruler attached to the tip of the piston rod is deformed and curved in accordance with the data stored in the control device, that is, in accordance with the ideal curved surface after the shaping operation.
