Installation structure of porous pipes for expropriating cable

An installation structure of porous pipes for accommodating cables is provided to allow ease of installation of porous pipes by reducing frictional force through the rotation of a roller. A communication pipe(100) has a plurality of cable accommodating holes(210). A rotation unit is arranged at the portion where a porous pipe(200) and the communication pipe contact each other, such that the rotation unit moves the porous pipe along the lengthwise direction of the communication pipe. The rotation unit includes a roller(400) rotatably arranged at one side of the porous pipe; and a rail(300) arranged along the lengthwise direction of the communication pipe in a lower portion of the communication pipe such that the roller contacts the rail.
