MAINTENANCE METHOD OF INSIDE OF WATER INTAKE AND DISCHARGE CHANNEL TUNNEL AND WATER INTAKE AND DISCHARGE PORT
To provide a maintenance method of an inside of a water intake and discharge channel tunnel and a water intake and discharge port in which inspection and repair of entire area of the water intake and discharge channel tunnel can be easily performed in a drying-up state.SOLUTION: In a water discharge channel tunnel 21 connected to a water discharge port 1 including a top slab 3, a bottom slab 5 and a side wall 7, a cover 11 is removed from a top slab opening 29 of the top slab 3, is lifted down to a bottom slab opening 31 provided in the bottom slab 5 so as to communicate with the water discharge channel tunnel 21, and closes the bottom slab opening 31. Then, while supplying air into an air supply and exhaust port 13 of the cover 11 via an air supply and exhaust pipe 15 from the water surface, water in the inside of the water discharge channel tunnel 21 is drained, and maintenance of the inside of the water discharge channel tunnel 21 is performed. While exhausting air from the air supply and exhaust port 13 of the cover 11 via the air supply and exhaust pipe 15 to the water surface, water is injected into the inside of the water discharge channel tunnel 21. Then, the cover 11 is removed from the bottom slab opening 31, is lifted up to the top slab opening 29, and closes the top slab opening 29.SELECTED DRAWING: Figure 1
【課題】取放水路トンネル全域の点検および補修を、ドライアップした状態で容易に行うことができる取放水路トンネル内のメンテナンス方法および取放水口を提供すること。【解決手段】頂版３と底版５と側壁７とを有する放水口１に連結された放水路トンネル２１において、頂版３の頂版開口部２９から蓋１１を取り外し、放水路トンネル２１に連通するように底版５に設けられた底版開口部３１まで吊り下げ、底板開口部３１を蓋１１で塞ぐ。次に、水上から給排気管１５を介して蓋１１の給排気口１３に給気しつつ、放水路２１トンネルの内部を抜水し、放水路トンネル２１の内部のメンテナンスを行う。そして、蓋１１の給排気口１３から給排気管１５を介して水上に排気しつつ、放水路トンネル２１の内部に注水する。その後、底版開口部３１から蓋１１を取り外し、頂版開口部２９まで吊り上げ、頂版開口部２９を蓋１１で塞ぐ。【選択図】図１
