The present invention provides a leakage prevention facility for a communication manhole, which can prevent rainwater or sewage from flowing into a manhole body. The leakage prevention facility for a communication manhole comprises: a manhole body constructed in the ground to provide a work space, and provided with a mounting protrusion part formed on the upper end thereof and allowing a cover member to be mounted thereon, a step member installed on an inner wall to allow a worker to enter, and a hole part formed on a lower portion thereof in a left and a right direction to allow a communication cable to pass therethrough; a common duct passing along the hole part formed on the lower portion of the manhole body, storing a plurality of communication cables, and connected to the inside of the manhole body to form an opening part; a door member slidably installed on the opening part to open and close the opening part; a switch part operated by the weight of the cover member when the cover member is mounted on the mounting protrusion part to convert a pressing force generated by the weight of the cover member into an operation to transfer the operation; a power transfer part converting the weight of the cover member transferred by the switch part into an opening/closing operation of the door member to transfer the opening/closing operation of the door member; a detachable fixing part fixing the cover member on the manhole body when the cover member is mounted on the mounting protrusion part, and releasing a closed state of the cover member by an operation of a worker; a sealing part installed on the edge of the cover member, and installed to protrude out of the cover member to finish the gap between the manhole body and the cover member; and a linking part converting an operation of the detaching fixing part into an expansion operation or a contraction operation of the sealing part depending on an open state or a closed state of the detaching fixing part to transfer the expansion operation or the contraction operation. 본 발명은, 지중에 시공되어 작업 공간을 제공하고, 상단에 덮개부재가 안착되는 안착턱부가 형성되며, 내벽에 작업자가 출입 가능하도록 계단부재가 설치되고, 하부에 좌우방향으로 홀부가 형성되어 통신 케이블의 통과될 수 있는 맨홀본체; 상기 맨홀본체의 하부에 형성되는 홀부를 따라 통과되고, 복수 개의 통신 케이블의 수납되며, 상기 맨홀본체의 내부와 연결되어 통하도록 개구부가 형성되는 공동구; 상기 개구부를 개폐할 수 있도록 상기 개구부에 슬라이딩 가능하게 설치되는 도어부재; 상기 덮개부재가 상기 안착턱부에 안착되면 상기 덮개부재의 자중에 의해 작동되어 상기 덮개부재의 자중에 의해 생성되는 가압력을 조작 작동으로 변환시켜 전달하는 스위치부; 상기 스위치부에 의해 전달되는 상기 덮개부재의 자중을 상기 도어부재의 개폐작동을 변환시켜 전달하는 동력전달부; 상기 덮개부재가 상기 안착턱부에 안착되면 상기 덮개부재를 상기 맨홀본체에 고정시키고, 작업자의 조작에 의해 상기 덮개부재의 폐쇄상태를 해제시키는 착탈고정부; 상기 덮개부재의 테두리에 설치되고, 상기 덮개부재 외측으로 돌출 가능하게 설치되어 상기 맨홀본체와 상기 덮개부재 사이의 간격을 마감하는 실링부; 및 상기 착탈고정부의 개방상태 또는 폐쇄상태에 따라 상기 착탈고정부의 작동을 상기 실링부를 팽창작동 또는 수축작동으로 변환시켜 전달하는 연동부를 포함하는 것을 특징으로 한다.
