By changing the length of the bolt that protrudes downward from the bottom of the manhole,
In the former case, the manhole body changes in the vertical direction, and in the latter case, the manhole body tilts.

た接面部である。(Embodiment) The illustrated embodiment of the present invention will be described based on FIG. Further, in the upper part of the bottom plate 2 and in the straight wall 3 of the manhole body 1, a culvert attachment opening 4 is provided to pass through the straight wall 3 of the manhole body 1. A substantially U-shaped notch 5 is provided on the lower surface of the bottom plate 2 at a position equidistant from the axis of the bottom plate 2 and opposite to the axis, and further, a cutout 5 is provided in the bottom plate 2 at an equal distance from the axis of the bottom plate 2, and a notch 5 is provided in the bottom plate 2, penetrating through the cutout 5. A screw hole 2a continuous to the portion 5 is bored, and a bolt 6 is screwed into the screw hole 2a. A nut 8 is screwed onto one end of the bolt 6 in a recess 7 provided in the upper part of the bottom plate 2, and the other end is made to protrude from the notch 5 to the bottom of the bottom plate 2. It is brought into contact with the upper surface of the foundation 10. Note that 11 is a contact surface formed at the other end of the bolt 6.

Since the lower surface of the bottom plate 2 is formed in a spherical shape, the manhole body 1 can be easily rotated along the foundation concrete 9 and the slope can be adjusted. Furthermore, even if the position shifts after construction, it can be easily corrected at any time until the foundation concrete 9 hardens. Further, to adjust the height, all bolts 6 may be loosened or tightened.

By using nuts, manholes can be laid regardless of the finish of the foundation, and foundation work can be done continuously in a short period of time with less labor. Moreover, even after the manhole has been laid, delicate positioning adjustments can be made until the foundation concrete hardens. Furthermore, since the configuration is simple, the complexity of the site and the number of steps are reduced, and therefore the work cost can be reduced.
