Abstract
A system and method for creating a subterranean storage facility at a location where there is underlying bedrock. A storage tank is provided that is formed from a cylindrical casing that is sealed with a top closure and a bottom closure. A first hole is excavated through the overburden. At the bottom of the first hole, a second hole is excavated into the bedrock. The storage tank is placed in the second hole with the top closure of the storage tank facing upward. The storage tank is set into the bedrock with a cement mixture. Pipe risers are extended into the storage tank through the first closure. The pipe risers extend up through the first hole and provide access to the storage tank.
Claims15
A method of forming a subterranean storage facility at a location where there is underlying bedrock covered by overburden, said method comprising:
- providing a storage tank having a cylindrical casing with a top closure and a bottom closure, wherein said storage tank has a maximum first width and a maximum first length;
- providing a secondary closure over said top closure, wherein an interstitial space exists between said top closure and said secondary closure;
- excavating a first hole through the overburden to access the underlying bedrock;
- excavating a second hole into the bedrock, wherein said second hole is wider and longer than said storage tank;
- erecting said storage tank in said second hole with said top closure facing said first hole, wherein gap spaces exist between said storage tank and said second hole when said storage tank is placed in said second hole;
- filling said gap spaces between said storage tank and the bedrock in said second hole with a cement mixture;
- extending pipe risers into said storage tank through said top closure, wherein said pipe risers extend through said first hole and provide access to said storage tank;
- and
- filling said first hole.
A method of forming a subterranean storage facility, said method comprising:
- providing a storage tank having a top and a bottom, said storage tank having a double container closure that contains a first closure and a second closure, wherein an interstitial space exists between said first closure and said second closure;
- excavating a hole into bedrock that is large enough to receive said storage tank therein;
- placing said storage tank in said hole with said top of said storage tank facing out of said hole, wherein gap spaces exist between said storage tank and said hole when said storage tank is placed in said hole;
- filling said gap spaces between said storage tank and the bedrock in said hole with a cement mixture;
- extending pipe risers into said storage tank, wherein said pipe risers extend out of said hole and provide access to said storage tank.
