PURPOSE: A high-pressure reservoir is provided to have improved structure by having improved sealability and stability,to minimize leakage of fluid. CONSTITUTION: A cavern(10) is formed by digging out bedrock and is for storing high pressure fluid. A lining(30) prevents leakage of fluid stored in a cavern and is installed in the inner side of the cavern to transfer fluid pressure to the bedrock. A shotcrete layer(31) is formed by placing a shotcrete onto the dig out side of the bedrock. The liner prevents leakage of fluid in the cavern by being spaced from the shotcrete layer at a specific interval. A backfill layer is filled between the liner and the shotcrete layer. A waterproof sheet is inserted between the liner and bagfil layer. The liner is formed of steel. The backfill layer is formed of concrete. A reinforcing material(35) is spread on between the waterproof sheet and liner to prevent shearing force on a frictional surface between the liner and the backfill layer. |
