る。The operation of the pavement plate cutting device according to the present invention is as follows. First, a position where the pavement plate cutting device suspended from the heavy construction machine arm 1 is to be cut, for example, a manhole cover 1.
5 and the rotary cutting bit 13 are installed concentrically. Next, the handle 4 is operated to adjust the height of the column 3 so that the cutting bit 13 is parallel to the upper surface of the paving slab 14. After confirming that the cutting bit 13 is parallel to the upper surface of the pavement slab 14, the entire pavement slab cutting device is pressed down from above with the arm 1 of the heavy construction machine and fixed. Next, when the hydraulic motor 10 is started, power is transmitted to the main shaft 12 via the gear device 11, and the cutting bit 13 attached to the lower end rotates. The elevating hydraulic cylinder 9 is operated to lower the inner frame 6 at a predetermined feed speed. The cutting bit 13 cuts the pavement plate at an appropriate feed speed while rotating so as to form a circular cutting groove in the pavement plate. At this time, the reaction force in the rotation direction of the cutting bit is received by the guide rod 8, and the reaction force in the vertical direction is received by the heavy construction machine arm 1.
