To increase or decrease as circumstances require the supply amount of cooling water and washing water while removing slurry during road surface cutting work of a pavement road surface by a road surface cutter.SOLUTION: An electric line pump 10 is arranged ahead of a branch for supplying cooling water for a circular blade 2 and washing water for cutting powder from a water tank 1. The branch branches on the downstream side into the circular blade cooling water and washing water. By interlocking the ON/OFF switch of the electric line pump 10 with the switch for a vacuum pump that sucks the used washing water and cooling water, the amount of cooling water supplied can be increased or decreased as circumstances require. The electric line pump is preferably a volute type pump. Thus, even if a cock installed on the downstream side of the pump is closed while the line pump is in operation to stop the supply of washing water, the probability of pump burn out is low.SELECTED DRAWING: Figure 1
【課題】路面カッター装置による舗装路面の切断作業において、泥水を路面から除去しながら冷却水・洗浄水の供給量を臨機応変に増減できるようにする。【解決手段】水タンク１から円形ブレード２の冷却水用と切削粉の洗浄水供給用への分岐の手前に電動ラインポンプ１０を配設し、その下流側に円形ブレード冷却水用と洗浄水用に分岐させ、電動ラインポンプ１０の入・切スイッチが使用済み洗浄水及び冷却水を吸引するバキュームポンプのスイッチと連動させることによって状況に応じて冷却水量の供給量を増減できるようにした。電動ラインポンプは、ボリュート型ポンプが好ましく、作動させた状態でポンプ下流側に設置したコックを閉じて洗浄水の供給を停止させてもポンプの焼損の確率が低い。【選択図】図１
