PREFABRICATED MANHOLE CONNECTING PIPE

摘要

PURPOSE: A prefabricated manhole connecting pipe is provided to prevent the inflow of concrete and improve the waterproof performance between a buried pipe and a connecting pipe by using a fixing member as a finger stop and pressing a waterproof member to fix on a pressing groove in a body. CONSTITUTION: A body(40) is provided with projections along an outer surface thereof. A fixing member(50) is coupled to an end of the body(40) and prevents the inflow of foreign materials into the inside of the body(40) upon pouring concrete. A waterproof member(60) is pressed to be fixed between the fixing member(50) and the body(40). A coupling member(70) is projected to be formed on either end of the body(40) to couple and fix the body(40).
