The present invention relates to a detachable manhole, and more particularly, to a detachable manhole that couples divided upper and lower manholes, wherein the lower manhole is formed into divided left and right manholes in order not to cut an existing pipe, thereby increasing working efficiency. The detachable manhole includes a lower manhole having a certain space formed inside and formed with separate left and right manholes, having a long through hole formed in the center of the outer part through which a water supply pipe passes; a tension steel cable penetrating through upper parts of the left and right manholes and supported by a joining unit on one or both sides to maintain joining force between the left and right manholes with a tension force; and an upper manhole joined with the top of the lower manhole, having a space inside. |
