综合管廊内燃气管道泄漏事故现场应急处置方案与决策分析

燃气管道入廊后表现出了良好的性能和潜力,对于提高燃气管道运维安全性具有重要意义。但应对突发事件,国内现行标准规范仅在事故风机启动要求、管道阀门切断要求等方面做了简单规定,可操作性不强。从燃气管道入廊安全技术角度出发,总结分析相对成熟的直埋燃气管道事故处置技术,重点论述在编制现场处置方案过程中存在的主要矛盾,并对廊内燃气管道泄漏现场处置方案编制思路和内容提出建议。

Analysis on Emergency Disposal Scheme and Decision of Gas Pipeline Leakage Accident in Utility Tunnel

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.
