Note that 44 and 44 in the elevation view in Figure 2 indicate the concrete or brick parts inside the manhole. 45
indicates the space inside the concrete manhole.

Claims (1)

[Scope of utility model registration request] The concrete manhole inner surface cutting machine of this invention has a base metal plate thickness of 5 cm width and 6 cm length of 45 cm.
It has an octagonal shape made of eight centimeter-sized iron pieces, and each seam is secured with metal screws by placing iron plates on the top and bottom. A metal plate rotating table with a diameter of 1 m and a thickness of 1 cm is attached on top of the table, and a long hole is made in the center of the table and a vertical rotating shaft is attached. The vertical rotary blade is operated by manual handle in the vertical, horizontal, and circumferential directions, and each degree of inclination is 15 degrees from the horizontal horizontal line.
A manual operation screw is provided on the rotary table plate. The main body of this concrete manhole inner surface cutting machine is equipped with a 22 horsepower motor.The rotary shaft rotary blade is driven by connecting a hydraulic chuck from the hydraulic motor, and the cutting cutting rotary blade is hydraulically operated. The rotary blade makes it possible to cut only the main work areas inside concrete manholes, and the metal friction noise generated during operation is reduced.
