1. A sealing structure of an underground high-pressure gas storage, arranged inside a gas storage, comprising:
an annular lining structure, wherein the annular lining structure is formed by enclosing a plurality of concrete segments;
closed steel sheets, wherein the closed steel sheets are arranged at an inner side of the annular lining structure and used for connecting two adjacent concrete segments and plugging a gap between the two adjacent concrete segments; and
a sealing layer, wherein the sealing layer is arranged close to the inner side of the annular lining structure and forms a coating with the annular lining structure on the closed steel sheets;
wherein each of the concrete segments has an equal arc length and the plurality of the concrete segments together form a circle; empty slots are respectively arranged near both ends of an inner side of each of the concrete segments; each of the empty slots is provided with an outlet towards an inner wall of each of the concrete segments; two ends of each of the closed steel sheets respectively enter the empty slots of the two adjacent concrete segments to form a connection;
two ends of each of the closed steel sheets are provided with T-shaped structures adapted to the empty slots; and
pressure sensors in contact with the T-shaped structures are arranged in each of the empty slots.
