Equipment for preventing water leakage of an electric communication manhole is provided to prevent an accident like an electric shock by having separate covers on left and right sides to be applied to an existing manhole. In equipment for preventing water leakage of an electric communication manhole(1), a plate-type blocking unit(11) has a size to cover a wiring hole(2a) of the electric communication manhole(1). A side wall(12) has an open space by being bent on a circumference of the blocking unit(11). A wiring hole is elongated to the wiring hole(2a) of the blocking unit(11). A cover(10) is composed of a plurality of bolt holes formed on the blocking unit(11) and a waterproof agent injecting hole(15) in communication with a space on the blocking unit(11). A plurality of anchor bolts mounts the cover(10) on the manhole(1). A waterproof agent(20) is injected to the space through the injecting hole(15) when the cover(10) is mounted on an outer surface of the manhole(1) to seal the wiring hole(2a) of the manhole(1). The cover(10) is composed of a pair of left and right cover units assembled to each other through a coupling unit by having a left and right symmetric structure. |
