Summary:PROBLEM TO BE SOLVED: To provide a cable trough with a ballast stopper by which, even if it is necessary to exchange the cable trough with a railroad related construction or even when searching for a cable fault, the work can be promptly performed while preventing the cable trough from being buried by gradually deforming a ballast formed from gravel or pebble groups and depositing them on the cable trough, the work is also simplified by integrally configuring a ballast stopper structure with the cable trough, and cost can also be reduced.SOLUTION: The cable trough with the ballast stopper includes: a cable trough body 1 that is substantially U-shaped; a ballast stopper wall 4 which rises upward from any one sidewall 3 and is substantially plate-shaped; a ballast stopper wall lock piece 9 which is spliced to both side faces and an upper end face of the wall and substantially U-shaped; a pile insertion member 12 in a hollow pipe shape fitted to a rear side of the ballast stopper wall lock piece; and a cable trough fixing pile 14 including an installation part 15 which is inserted through a hollow part of the pile insertion member and installed into the ground. 【課題】砂利や小石群によって形成されたバラストが徐々に崩れて、ケーブルトラフ上に堆積して、ケーブルトラフが埋もれることがなく、鉄道関連工事に伴うケーブルトラフ取替えが必要とされるときにあっても、ケーブル障害探索時にあっても、迅速に作業を行え、バラスト止め構造体をケーブルトラフと一体的に構成するため作業も簡単で、コストも安価になしえるバラスト止め付きケーブルトラフを提供する。【解決手段】略Ｕ字状をなすケーブルトラフ本体１と、いずれか一方の側壁３より上方に立ち上がる略平板状をなすバラスト止め壁４と、壁の両側面及び上端面に添接する略コ字状をなすバラスト止め壁係止片９と、バラスト止め壁係止片の裏面側に取り付けられる中空パイプ状の杭貫挿部材１２と、杭貫挿部材の中空部内を貫挿し、地中に打設される打設部１５を有するケーブルトラフ固定用杭１４を有する。【選択図】図１
