The present invention provides an angle adjustable manhole which is capable of adjusting angles according to the gradient of a ground surface (L). The manhole comprises a cylindrical pipe shaped fixing body (10) having a flow groove (11) which are bored from the upper side to the lower side thereof; an elliptical pipe shaped rotatory body (20) having a penetrating groove (21) having the fixing body (10), which is arranged in the lower side thereof and can be tilted, and a mounting groove (22) which allows an openable manhole cover (23) to be arranged on the upper side of the mounting groove; and a hinge unit (30) connected to the sides of the fixing body (10) and the rotatory body (20), wherein the rotatory body (20) is supported by the fixing body (10) to be able to rotate. Accordingly, the angle adjustable manhole according to the present invention prevents generation of noises due to travelling cars on a slope where a man hole is hardly flush with the surface of the ground, and protects a pedestrian from tripping on the manhole. |
