The present invention relates to a prefabricated manhole wherein an upper manhole and a lower manhole are coupled without using concrete or mortar necessary for a conventional manhole, and a coupling member is disassembled to be reused when replacing an upper body or lower body. The major configuration of the present invention comprises: a lower body(100) with an open upper part in which a lower supporting member(130) is formed inside on left and right surfaces or front and rear surfaces; an upper body(200) with an open lower body in which a supporting member(230) for the upper part is formed inside in the position corresponding to the lower supporting member(130) for the lower body(100); a lower coupling member(310) in which both ends support the lower supporting member(130) of the lower body(100), and a lower penetration hole(311) with top and bottom penetration portions is formed; an upper coupling member(320) in which both ends support the upper supporting member(230) of the upper body(200), and an upper penetration hole(311) with top and bottom penetration portions is formed; and a coupling member(300) which is composed of a fixing member(330) that is inserted into the upper penetration hole(321) of the upper coupling member(320) and the lower penetration hole(311) of the lower coupling member(310). |
