BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cutting machine for a manhole using an end mill,

The present invention relates to a cutting machine used for repairing a manhole using an end mill.

Generally, a lot of facilities such as a water pipe, a sewer pipe, a power cable, a communication cable, etc. are embedded in the underground of roads and indoors, and these various facilities should be repaired from time to time as needed. Therefore, manholes are installed at regular intervals for the maintenance of various facilities underground.

Typically, roads are overlayed at a period of 4 to 5 years, as roads become aged and uneven due to frequent car traffic and cracks occur in the ground.

However, since the surface of the road is higher than the surface of the existing manhole, the difference in height between the road surface and the manhole occurs when the road overlaying operation is performed. As a cause of the accident, the manhole must be repaired and the maintenance of the manhole must be made to match the surface of the overpassed road.

In the manhole repair work, the peripheral road surface layer of the manhole housing is vertically cut using a cutting machine, and then the vertically cut road surface layer is excavated and removed. When the manhole housing is raised, And then putting the manhole housing on top of it and filling and curing road paving material such as asphalt on the space part of the excavated and removed road surface layer.

However, in the conventional manhole repairing machine, since the road surface layer is to be cut linearly, the cutting line remains square and the worker can not cut the road surface layer squarely, and unnecessary cutting lines There is a problem in that not only a bad appearance but also an unnecessary part of the cutting line must be filled with the road wrapping material. In addition, there is a problem that noise and dust are generated in the crushing and excavation of the cut road surface layer, thereby causing inconvenience to passengers and automobiles passing around.

In order to overcome the above-described problems, the present applicant proposes Registration No. 10-0952069 and proposes a manhole repairing cutting machine, which can cut a road surface layer in a circular shape corresponding to the size of a manhole so as not to leave an unnecessary cutting line . However, it still does not solve the problem of generating noise and dust because the road surface is cut using a wheel cutter. Japanese Unexamined Patent Application Publication No. Hei 07-229158 proposes using an end mill instead of a wheel cutter. However, since the end mill is merely used by connecting an end mill to a drive motor in the field, the end mill There is a problem in that it can not be easily cut off by interposing in the road surface layer.
