DRAINAGE DITCH FORMING MEMBERS AND ROAD BRIDGE DRAINAGE DITCH REPLACEMENT AND REPAIR METHOD
To provide drainage ditch forming members and a drainage ditch replacement and repair method being durable and capable of preventing water from entering a concrete floor slab.SOLUTION: A drainage ditch forming member 1, being located between a ground covering part 3 of a road bridge concrete floor slab 2 and an asphalt pavement layer 4, has a bottom member 5 for running water placed on the exposed concrete floor slab 2, and a side wall member 6 erected on the ground covering part 3. The bottom member 5 for running water has a stainless steel plate 51 for stopping water having an L-shaped cross section and a waterproofing material 52 applied to the bottom of the cross section for running water. The side wall member 6 has a mortar 62 filled between a buried formwork 61 erected on the concrete floor slab 2 and the ground covering part 3. The buried formwork 61 has a vertical part 61a, a horizontal part 61b, and a hypotenuse part 61c that come into contact with a rising part 51b of the stainless steel plate 51 for stopping water. Attaching reinforcements 7 are attached to the side surfaces of the ground covering part 3, and the mortar 62 is filled between the buried formwork 61 and the ground covering part 3.SELECTED DRAWING: Figure 1
【課題】耐久性を有し、コンクリート床版内への浸水を防げる排水溝形成部材及び排水溝の交換補修工法を提供する。【解決手段】排水溝形成部材１は道路橋コンクリート床版２の地覆部３とアスファルト舗装層４との間にあり、表出するコンクリート床版２上に載置する流水用底部部材５と地覆部３側に立設する側壁部材６を有する。流水用底部部材５は、断面Ｌ字状の止水用ステンレス板５１と通水断面底部に施す防水工材５２を有し、側壁部材６は、コンクリート床版２に立設する埋設型枠６１と地覆部３との間に充填するモルタル６２を有する。埋設型枠６１は止水用ステンレス板５１の立上り部５１ｂに当接する垂直部６１ａと水平部６１ｂと斜辺部６１ｃとを有する。地覆部３の側面に付着用鉄筋７を取り付け埋設型枠６１と地覆部３との間にモルタル６２を充填する。【選択図】図１
