摘要
PURPOSE: A prefabricated polymer concrete manhole with upper and lower panels of variable cross section corresponding to stress is provided to reduce materials, required for manufacturing upper and lower panels, by analyzing stress generated in the upper and lower panels. CONSTITUTION: A prefabricated polymer concrete manhole with upper and lower panels of variable cross section corresponding to stress comprises a lower plate(10) and an upper plate(30). A protruding rib(17) is formed in the lower plate so that the bottom of a main body(20) is horizontally arranged. The upper plate is arranged between the main body and an upper body(40). A circular passage and a fitting groove are formed in the upper plate. The upper body is inserted into the fitting groove.
