After entering the utility tunnel, the gas pipeline shows good performance and potential, which is of great significance to improve the safety of gas pipeline operation and maintenance.However, in response to emergencies, the current domestic standards and specifications only make simple provisions on the requirements of the start-up of the accident fan and the cutting off of the pipeline valve, and it is not feasible.From the perspective of the safety technology of gas pipeline entering the corridor, the relatively mature accident disposal technology of directly buried gas pipeline is summarized and analyzed.The main contradiction existing in the process of preparing the on-site disposal plan is emphatically discussed, and the train of thought and content of the on-site disposal plan of gas pipeline leakage in the corridor are proposed.
