As shown in FIG. 8, when the inverted plate 12 is assembled with the half pipe portion 11, the flange portion 13 of the half pipe portion 11 is fitted between the fitting piece 15 and the inverted plate 12. When assembled, in the state in which the inverting device 10 is completed, there is a gap between the edge of the invert plate 12 and the side wall 120 of the manhole 100. Because when the inverted plate 12 is assembled, the inverted plate 12 should enter the manhole 100 and move horizontally in the direction of the flange portion 13 of the semi-pipe 11, so that the clearance for the horizontal movement is the horizontal inverted plate ( It is because it exists between the 13 and the side wall 130. Therefore, after the inverting apparatus 10 is assembled and covered on the inverting unit 110, the inverting plate 12 is disposed between the edge of the inverting plate 12 and the sidewall 120 of the manhole 100 before injecting the secondary filler 21. Fill in the gaps that exist. For example, the operation may be performed by padding a thin plate or applying a sealing material made of resin or the like between the gaps. Thus, after filling the gap existing between the edge of the inverted plate 12 and the side wall 120 of the manhole 100, the secondary filler 21 must be injected, so that the secondary filler 21 moves upward through the gap. It can be prevented from rising.

After the injection of the secondary filler 21, the fixing member 40, which fixed the half pipe portion 11 and the invert plate 12 to the side wall 120 of the manhole 100, was removed, and the fixing member 40 was removed.

The half pipe portion 11 and the inverted plate 12 may be made of various materials such as synthetic resin or steel, so that the prefabricated structure is assembled, so that the inverted portion can be easily and quickly repaired without plastering work. The maintenance time is shortened and the manhole can be used immediately after installation.

In addition, since the surface of the inverting device according to the present invention can be made evenly and smoothly, it is possible to smoothly eliminate the concern that the surface of the inverted portion becomes uneven by being manually laid in a narrow manhole space as in the conventional case.

In particular, the inverting device as described above has a configuration in which the half pipe portion 11 and the invert plate 12 are assembled, and the bottom pipe portion 11 is first installed, and then the bottom of the manhole 110 in which the invert plate 12 is planned. Since it is assembled to the half pipe portion 11 while being installed in accordance with the surface height, the installation of the invert device is very easy. In addition, since it has such a prefabricated structure, the filling operation of the filler can be performed by dividing into two steps, thereby ensuring the faithful filling of the filler.

Furthermore, in installing the inverting device according to the present invention, if the inverting device is made of a material having chemical resistance, the manhole can be used even where the sewage with severe pollution is increased due to increased chemical resistance of the manhole. have.
