Description
石炭溶融灰は噴流床石炭ガス化炉から発生する溶融灰である。
シート状の材料は、水流、潮流、波浪等の外力によって容易に破れる材料や、著しく水質を汚染するような材料以外であれば、材質、厚み、シート状や網状等の形状について特に規定するものではない。
本発明の水域環境保全材を水中に一個ずつ設置する場合は、図2(a)に示すように、船上クレーン3により水中に次々と設置していく。図は、鉄材(鉄筋又は鉄骨)の重り2を水域環境修復材(水域環境保全材料)1に線材などにより縛り付ける方法で取り付けた水域環境保全材の設置例である。
水域環境保全材料1を、漁礁のようにして水中に設置する場合を図5に示す。即ち、図示のように、シート状材料11の四隅に設けられた重りブロック12に建てた柱材13を梁材14で繋いだ台枠ユニット15を用い、シート状材料11上に多数の水域環境保全材料1を並べておく。こうしてシート状材料11上に多数の水域環境保全材料が並べられた台枠ユニット15を船上クレーンにより水中に設置する。
水域環境保全材料1を適当な間隔を開けて水中に設置していく場合を図8に示す。即ち、図示のように、作業船21において、帯状のシート材料を巻きつけたロールシート30からシート31を引き出して、そのシート31上に重りブロック32及び水域環境保全材料1を並べていく。シート31上への重りブロック32及び水域環境保全材料1の設置は、船上クレーン23により行い、特に水域環境保全材料1については、台船25上に大量に積み込まれた水域環境保全材料1の山から船上クレーン23により積み替えて行う。
