期は数時間という短時間で終了することが可能である。With the conventional structure, as described above, it was necessary to dig the surrounding asphalt road surface before raising and lowering the work. However, in the case of the present invention, there is no need to dig the asphalt road surface. That is, by rotating the bolt 4, the lid receiving frame 7 can be easily moved up and down, and after completion of the work, the work is completed by a simple operation of filling a gap formed between the lid receiving frame 7 and the asphalt road surface with a caulking material. Thus, the construction period can be completed in a short time of several hours.

作すればよい。Next, the procedure for adjusting the inclination angle will be described. The procedure is the same as the above-described raising and lowering work. In this case, the upper surface of the lid receiving frame 7, that is, the upper surface of the manhole cover coincides with the inclination of the road surface. The bolts 4, 4, and 4 may be operated so as to perform the operation.

することができることは自明である。In the embodiment, in the case of a normal 650 mm manhole, the height of the outer cylinder 1 is 110 mm, the gap between the upper rim 6 of the outer cylinder 1 and the lid receiving frame 7 is 8 mm, and the body of the outer cylinder 1 is When the gap between the inner surface and the outer peripheral surface of the lid receiving frame 7 was 3 mm, the inclination could be changed from 0 ° to about 5 °, which was sufficient for practical use. It is obvious that the inclination angle can be made to be more than this inclination angle by selecting these gaps.

たものである。As described above, in the manhole cover receiving frame according to the present invention, the adjustment of the height and the adjustment of the inclination angle can be easily performed from the top by operating the screw rod for the jack, ie, the jack bolt 4. It is possible to shorten the raising and lowering work and the inclination angle adjusting work in a manner inconceivable in the prior art, and the scale is provided on the outer surface of the lid receiving frame, so that the predetermined height (position) can be obtained. It is advantageous in that the structure of the manhole cover receiving frame is practically effective.
