DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for cutting a groove by moving a cutting machine along the curved surface using a guide device that resembles the curved surface when cutting a groove into a curved surface such as an inner wall of a tunnel; Regarding that fragile guide device.

For example, if water leaks from the inner wall of a tunnel,
Repair work is carried out by digging a groove in the inner peripheral wall and fitting a rubber groove cover into the opening of the groove to form a hollow gutter, which directs leakage water to the drainage grooves at the lower ends of both sides.

Conventionally, when cutting grooves on such curved surfaces, it was done by hand-held with a portable cutter powered by a gasoline engine, or by using many straight guides to create a polygonal shape that almost followed the curve. After assembling the equipment, the cutting machine can be installed and removed from each side of the guide device to cut into a polygonal shape, or in the case of a tunnel of a certain standard, it can be cut using an integrated guide device that matches the shape of the tunnel.

These conventional methods, when used manually with a portable cutter, are extremely labor-intensive, work slowly, produce poor results, and are expensive. In addition, when using a polygonal guide device, the working conditions are somewhat relaxed, but in terms of efficiency, there is not much difference from manual operation, the finished state is polygonal, and cutting is done in sections, so it is not sufficient. I can not say. Furthermore, since dedicated guide devices are used only for tunnels that meet the standards, they are of no use for non-standard guide devices, and their use is limited. This invention was developed through research in order to solve the above-mentioned conventional drawbacks, to be able to be used universally and widely for cutting any curved surface, and to cut efficiently and accurately. This will be explained in detail with reference to illustrative diagrams.

Furthermore, in the illustrated example, as shown in FIG. 6, three blades 9 are attached to the rotating shaft to cut three grooves in the wall surface 12, but this is as shown in FIG. When a wedge 13 is driven into the groove in the middle, a crack 14 appears as shown by the broken line connecting the far ends of the grooves, and the dirt and stones between each groove can be easily removed, and the details can be finished by chiseling. As a result, the entire gap between the grooves on both sides is cut out, creating a groove with a predetermined width on the left side.

By using the method of the present invention and the guiding device, no matter what kind of curved surface there is, the short guiding device can be freely curved to follow the curved surface, and the length can be freely continuous and integrated. A guide device can be easily installed on site, and the cutting machine can be moved along with the guide device using power.
It can be used universally regardless of the location, the condition of the curved surface, or the length of the curved surface, and since continuous cutting is performed using a single, stiff guide device, true grooves of the same depth can be cut, resulting in a very impressive finished state. Moreover, it eliminates overwork, allows construction to be completed in a short time, is truly economical, and has substantially excellent effects.
