The main body 111 has a mounting member 128 mounted on one side of the first panel 121 along the outer periphery of the first panel 121 and a mounting member 128 A part of the air pad 113 is disposed inside the mounting member 128 and a mounting member 129 having a shape of "a" is formed on one surface of the second panel 122 The opening of the mounting member 129 is directed to the outside and the remaining part of the air pad 113 is disposed inside the mounting member 129. [

The width adjusting means 127 is any one of an air cylinder and a support pipe.

The air cylinder is already well known. As is well known, the support pipe is fitted in the base pipe so that the movable pipe can be drawn in / out, and the water spiral portion of the movable pipe is fastened to the arm spiral portion of the base pipe, The entire length can be adjusted by turning the movable pipe in either one direction or the opposite direction.

The air pad 113 is formed with a wrinkle portion 116 in the middle so that when the width of the first panel 121 and the second panel 122 is increased by the width adjusting means 127, ).

The length of the width adjuster 127 is reduced so that the first panel 121 and the second panel 122 are overlapped with each other so as to be supplied to the sewer pipe. The width of the first panel 121 and the second panel 122 is increased by the width adjusting means 127 so that the widths of the first panel 121 and the second panel 122 Which is close to the inner surface of the sewer pipe.

Thereafter, air is supplied to the air pad 113 to expand the air pad 113, so that the air pad 113 is separated from the periphery of the first and second panels 121 and 122 and the inner surface of the sewage pipe .

When the main body 11 composed of the first panel 121 and the second panel 122 is manufactured as described above, it is possible to reduce the width of the main body 11 and to lower the main body 11 down to the manhole, The widths of the first panel 121 and the second panel 122 are increased so that the side ends of the first panel 121 and the second panel 122 are arranged as close as possible to the inner surface of the sewer pipe There is an advantage to be able to adjust.

7 and 8, the support beam 150 is formed in the form of an H beam, and a first upper shaft support 153 and a second lower shaft support 154 are mounted in a groove 152 A first spiral shaft 154 is rotatably mounted on the first upper spindle support 153 and the second lower spindle support 153 and the first spiral descent block 155 Is disposed between the upper shaft support 152 and the lower shaft support 153 and the second upper shaft support 158 and the lower shaft support 159 are mounted on the opposite groove 157 of the groove 152 A second spiral shaft 160 is rotatably mounted on the upper spindle support 158 and the lower spindle support 159 and a second ascending / descending block 161 fastened to the second spiral shaft 160 is rotatably mounted on the upper spindle shaft 158, And is disposed between the pedestal 158 and the lower pedestal support 159.

9, the support beam 150 constructed as described above is installed in one manhole 2 of the sewage pipe 1 as follows.

A plurality of support beams 150 are installed at the inlet 2a of the sewage pipe 1 located relatively downstream in the manhole 2 when sewage flows in the direction of the arrow 8 in Fig. 9, in a state where the support beam 150 is set up, the second ascending / descending block 161 is rotated so that the second ascending / descending block 161 ascends, The supporting beam 150 is pressed by being pressed against the inner surface of the ceiling 1a of the main body 1 to fix the standing support beam 150. [

Thereafter, the water tray 110 is lowered through the manhole 2 so as to be closely attached to the support beam 150 and the first spiral shaft 154 is rotated so that the first lift block 155 moves the water tray 110 So that the lower end of the water diaphragm 110 is brought into close contact with the bottom surface 1b of the sewage pipe 1.

10, when the support beam 150 is lifted up from the manhole 2 to the inlet 2a of the sewer pipe 1, when viewed from the direction of the arrow 8 in which sewage flows, Is slightly inclined so as to be slightly ahead of the upper end 151b.

When the support beam 150 is inclined as described above, the lower end 151a of the support beam 150 is strongly adhered to the bottom surface 1b of the sewage pipe 1, so that the support beam 150 is improved in bearing capacity.

10, the dam plate 110 is coupled to the support beam 150 by the bolts 210 and the nuts 211 while being supported by the support beams 150. As shown in Fig.
