PROBLEM TO BE SOLVED: To provide a soundproof-sound absorption device for track maintenance work optimal for the track maintenance work of a rail.SOLUTION: The soundproof-sound absorption device comprises a soundproof-sound absorption part 11 erected by a structural material, by providing at least any one of a soundproof member and a sound absorption member on at least longitudinal-lateral side surfaces so as to cover a part between two track rails R in the predetermined length in the direction of the track rail R and a guide mechanism part 12A for guiding so that the soundproof-sound absorption part 11 moves along the track rail R. Here, the guide mechanism part 12A comprises a plurality of piles 12A1 fixed by driving the pile along the track rail R in an outside roadbed of the respective track rails R, a guide rail support member 12A2 provided in the respective piles 12A1, a guide rail 12A3 provided in the guide rail support member 12A2 along the track rail R and a guide roller 12A4 provided in a lower end part of the soundproof-sound absorption part 11 and traveling along the guide rail 12A3. |
