An assembling equipment of a prefabricated manhole is provided to prevent vertical separation between spherical bodies when the ground subsides and to prevent damage of the sphere formed with the concrete. An assembling equipment of a prefabricated manhole comprises a latch(20) and a fastener(12) which are elastic. Bonding grooves with holders(24) in the upper and lower parts of manhole spheres(4,8) capable of being stacked are formed. In the state that the upper and lower part bonding grooves face to each other, the latch is inserted in the holder. The fastener comprises a connecting bolt(14) which is bolt-coupled through the coupling holes of the latches. The top of the latch is bolt-coupled in the state which a reinforcing piece(18) is placed. The reinforcing piece is formed in order to cover the entire top of the latch. In the holder, a coupling space(30) which enables fastening of a bolt head(14a) and a nut(22) of the connecting bolt is formed. |
