A prefabricated manhole and an installation method using a multi-segment are provided that the time required for the assembly can be minimized and the assembly accuracy of segment is improved. A prefabricated manhole and an installation method using a multi-segment comprise a prefabricated manhole main body(100) in which space at the constant size is formed in inside, and a penetration portion for the pipe conduit formation is formed in a side, and a prefabricated pipe conduit which is formed in the penetration portion of prefabricated manhole main body. The prefabricated manhole main body comprises a lower slab(1), segments(5,9) for multi-layer laminated wall on the top of the lower slab, segments(7,8) for the multi-layer pipe conduit formation wall, and an upper slab(3). |
