PURPOSE: A plastic manhole comprising a fiber-reinforced plastic support is provided to prevent the body of a manhole from becoming crushsed or separated from a flange due to soil pressure. CONSTITUTION: A plastic manhole comprising a fiber-reinforced plastic support is as follows. An FRP support is fixed to the outside of a manhole body(10). The FRP support consists of a circular body fixing unit and a flange fixing unit(50). The inscribed surface of the circular body fixing unit is formed to have the same size to the outer circumferential surface of the body and the circular body fixing unit has a given thickness. The flange fixing unit has a given thickness and is vertically extended toward the outside of the body fixing unit. Adhesive is applied to the outside of the body, to which the FRP support has been fixed, and then FRP resin(80) is coated.
