UNDERGROUND HIGH-PRESSURE FLUID RESERVOIR HAVING IMPROVED SHEARING STRENGTH OF BEDROCK AND COMPRESSED AIR ENERGY STORAGE SYSTEM USING SAME

摘要

The present invention relates to a high-pressure fluid reservoir to store high-pressure gas in an underground core part. The high-pressure fluid reservoir, according to the present invention, comprises: a tank body which is embedded in a cavern formed by excavating the ground downward to store high-pressure fluid, is made of a sealable material, and has a receiving part where the high-pressure fluid is stored; a backfill layer which is formed by a backfill material filled between the tank body and the cavern; a plug which closes the cavern; and a strength reinforcement which is inserted from the inner wall of the cavern into the bedrock to improve the shearing strength of the bedrock arranged on the top of the plug.;COPYRIGHT KIPO 2016
