Claims

[Scope of utility model registration request]

The lower parts of the front and rear ends of the two main and subterranean underground storage sides 1 and 2, which are excavated horizontally in parallel in the underground bedrock, are fed into each other and connected through the communication hole 3 and the natural flow passage hole 4, forming the main underground storage cave. A plug 5 is installed perpendicularly and perpendicularly to the infeed communication hole 3 near the entrance of the infeed communication hole 3 on one side (near the inlet of the infeed communication hole 3 on one side that sends storage water from the underground storage cave 1 to the sub-underground storage cave 2).
Insert the pipe shaft 6.7 for pre-injection into the main underground storage cave 1 from above up to the vicinity of the main underground storage cave bottom 1a at the front of the entrance of the main underground storage cave 1, and feed the lower end of the pipe shaft 6 for injection into the communication hole 3. While bending to the side, the open end of the pipe shaft 6 passes through the plug 5 and opens to the feed communication hole 3 side on the side of the sub-underground storage cave 2, and the bottom floor of the feed communication hole 3 on the side of the sub-underground storage cave 2. A concrete bottom floor 8 is formed in a part of the bottom floor part of the sub-underground storage cave 2 which is continuous with the part, and a pipe shaft 7 for discharge is installed in the pivot 1 pivot 9 provided in the main underground storage cave 1. An underground cave characterized by being formed by insertion.
