DEPLOYMENT METHOD OF UNDERWATER CONTAMINATION PREVENTATIVE DEVICE
To provide a deployment method of an underwater contamination preventative device deploying a contamination preventative membrane in a tensed state even at the time of a low water level.SOLUTION: A deployment method of an underwater contamination preventative device comprises mooring a lower edge part of a contamination preventative membrane of the underwater contamination preventative device in which a float is provided on an upper edge part of a shield body upon deployment of the contamination prevention membrane in an area where a water level is fluctuated, the contamination preventative membrane is provided on a lower edge part of the shield body, auxiliary floats are provided at positions near a water surface of the contamination preventative membrane at the time of a lower water level, and heavy weights are provided on the contamination prevention membrane at the shield body side closer to a middle position between the auxiliary floats and the lower edge part of the shield body.SELECTED DRAWING: Figure 6
【課題】低水位時においても汚濁防止膜を緊張状態に展張する水中汚濁防止装置の展張方法を提供することにある。【解決手段】水位が変動する水域に汚濁防止膜を展張するに当り、遮蔽体の上縁部にフロートを設け、前記遮蔽体の下縁部に汚濁防止膜を設け、かつ低水位時の汚濁防止膜の水面近傍部位に、補助フロートを設け、該補助フロートと遮蔽体下縁部間の中間点部位より遮蔽体側の汚濁防止膜に重錘を設けてなる水中汚濁防止装置を、該水中汚濁防止装置の汚濁防止膜の下縁部を水底に係留してなる、水中汚濁防止装置の展張方法。【選択図】 図６
