CAISSON INFILLING MATERIAL-CHARGING METHOD
PROBLEM TO BE SOLVED: To provide a caisson infilling material-charging method capable of preventing occurrence of turbidity of seawater by the infilling material, and capable of preventing reduction in a weight per unit volume caused by fall through water, of the infilling material, in a case that slag or the like is used as the infilling material of a caisson.SOLUTION: A caisson infilling material-charging method: installs a charging pipe 10 so that a lower end of the pipe 10 extends up to the vicinity of a bottom part BT of the caisson CA, in the inside of the caisson CA; injects air into a lower part of the charging pipe from an opening/closing type cover part so that water does not enter from the lower end 10a of the charging pipe and so as to close the opening/closing type cover part 20 provided in the inside of the charging pipe; charges the infilling material FM from an upper end of the charging pipe; opens the opening/closing type cover part by pressure by a dead weight of the charged infilling material; drops the infilling material through the air in the charging pipe; and discharges the infilling material to the bottom part of the caisson from the lower end of the charging pipe. Next, the caisson infilling material-charging method repeats injection of the air and charging of the infilling material after pulling up the charging pipe by a predetermined height.
【課題】ケーソンの中詰材としてスラグなどを用いた場合、その中詰材による海水の濁りの発生を防止できるとともに、中詰材の水中落下による単位体積重量の減少を防止できるケーソン中詰材投入方法を提供する。【解決手段】このケーソン中詰材投入方法は、ケーソンＣＡの内部にその底部ＢＴ近傍まで下端が延びるようにして投入管１０を設置し、投入管の下端１０ａから水が進入せずかつ投入管の内部に設けられた開閉式蓋部２０が閉塞するように開閉式蓋部から下方の投入管内に空気を注入し、投入管の上端から中詰材ＦＭを投入し、投入された中詰材の自重による圧力によって開閉式蓋部が開放し、中詰材が投入管内の気中で落下し、投入管の下端からケーソンの底部へと中詰材が排出され、次に、投入管を所定高さだけ引き上げてから空気の注入および中詰材の投入を繰り返す。【選択図】図１
