MUDDY WATER DIFFUSION SUPPRESSION DEVICE AND MUDDY WATER DIFFUSION SUPPRESSION METHOD
PROBLEM TO BE SOLVED: To suppress the diffusion of muddy water generated in accordance with the installation of a pile under water with a more compact and simple configuration.SOLUTION: An operator delivers a main wining wire 33 of a crane 31 to allow the lower end of a guide pile 2 to reach a water bottom 35, and delivers an auxiliary wining wire 32 to allow a muddy water diffusion suppression device 1 to freely fall along the guide pile 2. Thus, the muddy water diffusion suppression device 1 is arranged at a position to cover a portion that contacts the water bottom of the guide pile 2 in the installation place in a state that the guide pile 2 is put through an opening 103 and a hollow part, and its apex is submerged. While muddy water is generated from the vicinity of the portion that contacts the water bottom of the guide pile 2 in the installation place in accordance with the installation of the guide pile 2, the muddy water stays in the hollow portion of the muddy water diffusion suppression device 1. Since a gap between the edge of the opening 103 and the guide pile 2 is reduced due to an elastic member 104, the quantity of the muddy water which leaks from the muddy water diffusion suppression device 1 is also equivalently suppressed.
【課題】水中での杭の打設に伴って発生する濁水の拡散を、より小型且つ簡易な構成で抑制すること。【解決手段】作業者は、クレーン３１の主巻用ワイヤ３３を繰り出して導杭２の下端を水底３５に着底させてから、補巻用ワイヤ３２を繰り出して濁水拡散抑制装置１を導杭２に沿って自由落下させる。これにより、濁水拡散抑制装置１は、開口部１０３及び中空部に導杭２が通されてその頂部が水没した状態で、打設箇所における導杭２の水底に接する部分を覆うような位置に配置されることになる。導杭２の打設に伴って、打設箇所における導杭２の水底に接する部分付近から濁水が発生するが、その濁水は濁水拡散抑制装置１の中空部内に留まる。弾性部材１０４により開口部１０３の縁と導杭２との隙間は小さくなっているから、濁水拡散抑制装置１から漏れ出る濁水の量も相当に抑制される。【選択図】図１
