[0002] The sealing layer of the gas storage cavern is a crucial step in sealing the cavern, forming the main enclosed structure of the gas storage facility. After the concrete lining of the gas storage cavern is completed, dust is cleaned from the lining surface, and then the sealing layer construction begins. However, manual sealing layer application presents challenges. During spraying, the distance between the spray nozzle and the sprayed surface may vary, resulting in uneven spray thickness and low-quality sealing layer. Furthermore, the rebound of the material during manual spraying poses a safety hazard to personnel. Additionally, manual spraying of missed areas leaves a layer of material that is prone to later detachment, and also results in low spraying efficiency. Summary of the Invention
