Polymer Circular Manhole Assembly System
In the present invention, when a circular lid body is opened or closed by a hinge-coupling structure at an eccentric location out of a circle, the circular lid body can be opened or closed without interference between an edge protrusion part of the circular lid body and a circular edge support frame of a support frame body. Therefore, the present invention is useful in that the present invention has overcome innumerable interferences on arcs through a curve insertion scheme of a circular structure, that is, a curve insertion scheme by a rotational inclination angle θ of the edge protrusion part and an operation model view of an S-shaped hinge curve part.
