CLEAN WATER AREA FORMATION APPARATUS AND CLEAN WATER AREA FORMATION METHOD
PROBLEM TO BE SOLVED: To provide a clean water area formation apparatus and a clean water area formation method suitable for performing underwater work on a wall body such as a dam wall body in a clean water area where visibility can be secured.SOLUTION: A casing part 200 of a clean water region forming apparatus 100 includes a case 210 (water discharge part) for discharging clean water along a wall body 10, and a surrounding part 220. The surrounding part is fixed to the open surface of the case 210 and is connected to the wall body 10 to surround the flow of fresh water discharged from the case 210. A turbid water raised by a submersible pump 400 is filtered by a filtering device 300 on a barge 30, the clean water generated by the filtering device 300 is sent to the case 210, and discharged from the open surface of the upper surface of the case 210, thereby forming a clean water area in the surrounding part 220.SELECTED DRAWING: Figure 1
【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１００の筐体部２００は、壁体１０に沿って清水を放水するケース２１０（放水部）と、ケース２１０の開放面に固定され、壁体１０と連接してケース２１０から放水される清水の流れを囲む囲み部２２０とを備える。そして、水中ポンプ４００によって揚水された濁水を台船３０上の濾過装置３００で濾過し、濾過装置３００で生成された清水をケース２１０に送水してケース２１０上面の開放面から放水することで、囲み部２２０内に清水領域を形成する。【選択図】図１
