Description

Sealing and reinforcing structure of underground gas storage Technical Field The invention relates to the technical field of underground gas storage, in particular to a sealing and reinforcing structure of an underground gas storage. Background The compressed air underground gas storage is a gas storage system for storing and compressing air by utilizing underground spaces such as natural underground caverns, salt caverns or deep rock pores. For storing high pressure gas, the underground gas storage chamber walls are typically provided with a sealing layer. The conventional gas storage cavern is built underground, the sealing layer is a single layer, when vibration is encountered, the sealing layer of the single layer is easy to crack and seal and lose efficacy due to uneven stratum deviation stress, the sealing effect of the sealing layer is affected, the cavern cannot continuously store gas, meanwhile, the existing underground gas storage supporting structure is insufficient, the stability and reliability are difficult to meet the construction requirement of the underground gas storage, and the cost in the aspects of later repair and the like is high. Accordingly, there is a need for an underground gas storage seal reinforcement structure that solves the above-mentioned problems of the prior art. Disclosure of Invention The invention aims to solve the technical problem of overcoming the defects existing in the prior art and providing the underground gas storage sealing and reinforcing structure with good universality and sealing reliability. In order to solve the technical problems, the invention adopts the following technical scheme: A sealing and reinforcing structure of an underground gas storage comprises a sealing wall and a reinforcing component; the sealing wall is used for enclosing a gas storage cavity for forming an underground gas storage, the sealing wall comprises a lining layer, a functional layer and a rock layer which are sequentially arranged outwards from a sealing cavity, the functional layer comprises an outer sealing layer and an inner sealing layer, a plurality of gaps are correspondingly arranged on the outer sealing layer and the inner sealing layer one by one, and when the outer sealing layer and the inner sealing layer are staggered, the gaps on the outer sealing layer and the inner sealing layer can be mutually embedded; The reinforcing component comprises a first column body arranged on the sealing wall and a plurality of groups of second column bodies arranged on the sealing wall along the trend of the sealing wall at intervals, and the first column body is connected with each second column body through first reinforcing ribs. As a further improvement of the above technical scheme: and rubber layers for processing the notch are arranged on the outer sealing layer and the inner sealing layer. As a further improvement of the above technical scheme: The first column body is a semi-column, a center frame is arranged at the top of the first column body, and a plurality of groups of first reinforcing ribs connected with the second column body are arranged on the center frame.
