METHOD OF MAKING SLIT IN DRAINAGE CULVERT, AND EROSION CONTROL DAM HAVING DRAINAGE CULVERT
To provide a method of making slits in a drainage culvert and an erosion control dam having the drainage culvert capable of suppressing small gravel, sediment, and earth and stone in a drainage culvert, without using a closing plate.SOLUTION: A plurality of steel material drilling holes 130i for burying steel materials 140i are opened, from an inlet position IPi for burying a steel material drilling hole on a front surface FS which is determined based on separation Sep from the front surface FS of a dam body 110 on an upper face of a drainage culvert 120, to a predetermined depth under a lower face of the drainage culvert 120, with a prescribed angle. The steel materials 140i are respectively inserted into the steel material drilling holes 130i, to acquire an erosion control dam in which an inside of the drainage culvert 120 has a slit structure.SELECTED DRAWING: Figure 1
【課題】閉鎖板を使用しないで、水抜き暗渠内の小礫や土砂、土石を押さえることができる水抜き暗渠のスリット化方法及びその水抜き暗渠を有する砂防堰堤を得る。【解決手段】堤体１１０の前面ＦＳからの水抜き暗渠１２０の上面における離隔Ｓｅｐに基づいて決定した前面ＦＳにおける鋼材切削孔埋込入口位置ＩＰiから所定角度で、水抜き暗渠１２０の下面の所定深さまで鋼材１４０iを埋込むための複数の鋼材切削孔１３０ｉを空けて、これらの鋼材切削孔１３０ｉに、鋼材１４０ｉを各々挿入して水抜き暗渠１２０内をスリット構造にした砂防堰堤を得る。【選択図】図１
