Drainage pumping stations have been often damaged recently because of severe flood events caused by new-recorded torrential rains in any regions over Japan. Urbanization and the mixture state of rural and urban characteristics have been advanced in agricultural areas. In those areas, the drainage pumping stations for agricultural uses are potentially exposed to disaster risks and countermeasures for disaster risk reduction on the stations are urgently required by making the stations water resistant. The design standard, Pumping Stations, revised in May 2018 mentions that new and improved pumping stations should be built with water-resistant measures. However, existing pumping stations without water-resistance are necessary to satisfy the standard afterward. In our report, we investigated how the drainage pumping stations with water-resistance are in reality in the fields and reviewed past studies to see how they were. Our study revealed that the countermeasures were performed for the stations or the areas that were actually damaged by past floods. In addition, there are some advanced countermeasures against disasters on the pumping stations. For example, some countermeasures are ready on the assumption that electricity and water supply are stopped due to a potential Nankai Trough Earthquake. Nowadays, the pumping stations are improved with water-resistance on the management sectors for rivers and sewerages mainly in the urban areas., 既往最大雨量を記録するような豪雨が日本各地で多発する中,農業用排水機場が浸水し機能停止に陥る事例が発生している。農業用排水機場は農地排水を目的に計画されているが,都市化・混住化が進んだ地域では,排水機場の機能停止は住民の被災に直結する問題であり,耐水化による減災対策の重要性が増してきている。平成 30 年 5 月に改定された設計基準「ポンプ場」に耐水化対策が明記され,新設,更新施設では耐水化がなされることとなるが,既存の施設への対応は今後の課題である。本報では,排水機場の耐水化対策の現状及び先行した取組事例について調査を行った。農業用排水機場では,過去に浸水被害を被った地域,機場で対策が行われている。また,大規模津波で電気,水道が途絶した場合の対策を計画している事例がある。河川等類似施設では,都市部を中心に耐水化対策が進められている。}, pages = {119--129}, title = {大規模浸水に対応した農業用排水機場の耐水化対策の事例}, volume = {3}, year = {2019}, yomi = {セキジマ, ケンジ and キリ, ヒロヒデ and アゼチ, イッサク and キムラ, ノブアキ} }
