Abstract
The present invention provides a groove-type skeleton, a sealed lining structure, an underground gas storage, which belong to the technical field of compressed air energy storage. The groove-type skeleton includes a fixed bottom plate, which has a length direction and a width direction. The fixed bottom plate forms a semi-open receiving space along the length direction at the middle axis, and the top edge of at least one side of the semi-open receiving space extends inward to form a protrusion. The sealed lining structure includes an airtight layer and the groove-type skeleton. The underground gas storage includes a concrete lining layer and the sealed lining structure. The groove-type skeleton can be combined to form a sealed lining structure, which forms an underground gas storage. Its construction period is shorter than that of welded steel plates and its cost is lower.
