Underground gas storage hole lining structure

The invention provides a lining structure of an underground gas storage hole, aims to solve the problems that a steel plate of a steel plate layer is inconsistent with a secondary lining in deformation in the use process, the steel plate is easy to fall off, wrinkled and deformed and the like, and relates to the technical field of underground gas storage holes. The underground gas storage hole lining structure comprises a secondary lining and a steel plate lining and further comprises an inner supporting system. In the circumferential direction of the steel plate lining, the steel plate lining is provided with at least two convex arch slopes for external expansion compensation, the arch slopes are arranged at intervals, and a gap is formed between the inner side face of the second groove and the outer side face of each arch slope so that a deformation receding cavity can be formed; the deformation receding cavity is filled with an elastic supporting body attached to the outer side face of the arch slope.
