The present invention relates to a manhole for protection of a communication cable for construction, and an object of the present invention is to protect the manhole from ground behavior through an easy operation without changing the structure of the manhole, and also to help the wiring work of the communication cable and reduce damage. Construction communication cable protection manhole according to the present invention, the manhole body 10 is opened and closed through a cover and a communication cable is routed therein; It is installed symmetrically on the periphery of the manhole body and includes a manhole body support for supporting the manhole body through a pressing force on the ground, and the manhole body includes a support mounting groove 11 that is opened toward the outside on the periphery. And, the manhole body support is a fixing frame 20 which is inserted and fixed into the acupressure plate mounting groove of the manhole body, a socket 25 for fixing the fixing frame, and is tiltably connected to the fixing frame and protrudes out of the fixing frame to the ground It includes an acupressure plate 30 supported on and a link 40 for guiding the tilting of the acupressure plate and maintaining an angle, and the fixing frame extends through the bottom plate 21, corrugated plates on both left and right sides of the bottom plate Alternatively, the left and right side plates 22 that are retractably connected, the rear plate 23 connected to at least one side of the side plate and the bottom plate, and a hub 23a formed on the rear plate and through which the communication cable is routed and the socket is coupled Including, the acupressure plate is formed along the vertical direction and includes a wiring closet hole 32 through which a communication cable routed through the manhole body passes, and the link is a curved rail along the rotational trajectory of the acupressure plate. While including one side is fixed to the acupressure plate is supported through a fixture on the side plate.
