The present invention relates to a detachable waterproofing manhole through which a multipurpose pipe (M) laid underground is penetrated including a manhole cover (10); an upper body (20) having the top whereon the manhole cover (10) is installed and a first connecting flange (22) along the lower inner circumference; a lower body (30) having a second connecting flange (32) in contact with the first connecting flange (22) along the upper inner circumference and installed on the lower part of the upper body (20) through which the multipurpose pipe (M) is penetrated; and multiple coupling members (40) installed on the first and second connecting flanges (22, 32). According to the same, the present invention is capable of preventing corrosion of the coupling members, minimizing excavation when separating the manhole body for maintenance of the multipurpose pipe, and easily separating the upper and lower bodies by easily removing the coupling members. In addition, the present invention minimizes ...
