ROAD BRIDGE PROTECTION FENCE AND ITS INSTALLATION METHOD
PROBLEM TO BE SOLVED: To provide a road bridge protection fence which is excellent in durability, and can shorten a construction time, and its installation method.SOLUTION: This road bridge protection fence comprises: a continuous fiber-reinforced material which is erected on a side end of a floor plate; a precast wall material which has a penetration hole capable of accommodating the continuous fiber-reinforced material, and is installed on the side end of the floor plate so as to accommodate the continuous fiber-reinforced material in the penetration hole; and a cement system filler filled into a gap in the penetration hole. By using the continuous fiber-reinforced material as a reinforcing material, high rigidity is obtained, and the lowering of durability caused by corrosion by a water content, a salt content or the like can be suppressed.SELECTED DRAWING: Figure 1
【課題】耐久性に優れ、工期短縮が可能な道路橋防護柵及びその設置工法を提供する。【解決手段】この道路橋防護柵は、床版の側端部に立設された連続繊維補強材と、連続繊維補強材を収容可能な貫通孔を有し、この貫通孔に連続繊維補強材を収容するようにして床版の側端部の上に設置されたプレキャスト壁材と、貫通孔内の隙間に充填されたセメント系充填材とを具備する。連続繊維補強材を補強材として用いたことによって、高強度で、水分や塩分等による腐食による耐久性の低下を抑えることができる。【選択図】図１
