CLEAR WATER REGION CREATION DEVICE AND CLEAR WATER REGION CREATION METHOD
PROBLEM TO BE SOLVED: To provide a clear water region creation device and a clear water region creation method suitable to enable underwater work on a wall of a dam body to be executed in a region filled with clear water to secure visibility.SOLUTION: A clear water region creation device 1 comprises: an enclosure section 30 having a pair of wall members 31a and 31b arranged opposite to each other in a horizontal direction on an underwater wall 40 of a dam body; and a water supply section 2 which supplies clear water from bottom side of the enclosure section 30. The clear water region creation device 1 creates: an enclosure region 32 with the wall 40 and the wall members 31a and 31b in a manner that brings edges of the wall members 31a and 31b into contact with the wall 40; and a clear water region inside the enclosure region 32 with the clear water supplied to the enclosure region 32 along the wall 40 through the water supply section 2.SELECTED DRAWING: Figure 2
【課題】ダム堤体などの壁体についての水中作業を、視界を確保できる清水領域で行わせるのに適した、清水領域形成装置及び清水領域形成方法を提供する。【解決手段】清水領域形成装置１は、ダム堤体などの水中の壁体４０の左右方向に対向する一対の壁部材３１ａ、３１ｂからなる囲い部３０と、囲い部３０の底側から放水する放水部２とを備える。そして、清水領域形成装置１は、壁部材３１ａ、３１ｂの端縁を壁体４０に付けることで壁体４０及び壁部材３１ａ、３１ｂで囲み領域３２を形成し、放水部２は、壁体４０に沿うように囲み領域３２内に清水を放水して囲み領域３２内に清水領域を形成する。【選択図】図２
