Japanese Patent JP4588151
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simplify construction processes, and improve durability. SOLUTION: A storage facility in a bedrock is provided with a pressure-proof shock absorbing member 14 installed on the inner surface side of a cavity part 12 formed in a bedrock 10, and a gas-tight member 16 such as a gas-tight metal lining layer provided on the inner surface side of the pressure-proof shock absorbing member 14. The pressure-proof shock absorbing member 14 is composed of porous concrete provided with gas permeability and water permeability. A space 18 is provided inside the pressure-proof shock absorbing member 14. Inside the space 18, a gas sensor is installed. The pressure-proof shock absorbing member 14 of porous concrete is provided with functions as a draining passage and a leakage detecting passage.
