平駄船の英語

作業本船の前進に応じて水底の堆積土砂を均しながら掻き集めて水面上の浚渫土砂貯溜手段まで連続的に圧送できるようにして、従来の浚渫で必要とした大型のグラブ等が不要となり、また浚渫後の水底面が略平坦として浚渫を計画レベル通りに無駄なく行うことが可能となり、更に浚渫に伴う周辺水域の土砂拡散、汚濁を効果的に抑える。例文帳に追加

To effectively restrain diffusion of sediment and pollution of a surrounding water area caused by dredging by serviceably dredging as a planned level by making a dredged water bottom surface substantially flat without requiring a large glove required in conventional dredging by continuously forcibly feeding up to a dredging sediment storage means on a water surface by scraping up while leveling deposit sediment of the water bottom in response to an advance of a work mother ship. - 特許庁
