天然气是我国主要的清洁能源,广泛应用于工农业生产和人民的日常生活中,有利于节约能源、保护环境。随着我国经济水平的不断提高,现代化进程加快,城镇燃气管道的设计也逐渐完善。我国《城镇燃气设计规范》中规定:燃气管道在穿越城镇主干道时,施工中应敷设过路套管保护燃气管道。根据许多城市多年来的应用成果,敷设过路套管虽然对过路燃气管道起到了一定的保护作用,但另一方面也给道路安全带来了极大的威胁。本文将论述城镇燃气管道敷设过路套管的优点和弊端,阐明取消过路套管的好处,总结保护城镇燃气管道的措施。
Natural gas is China’s major clean energy, widely used in industrial and agricultural production and people’s daily life, is conducive to energy conservation and environmental protection. With the continuous improvement of China’s economic level, the modernization process has been accelerated and the design of urban gas pipelines has been gradually improved. China’s “Urban Gas Design Code” provides: gas pipeline crossing the main road in the town, the construction should be laid over the road to protect the gas pipe casing. According to the application results of many cities over the years, laying of the bushing has played a protective role in crossing the gas pipeline, but on the other hand it also poses a great threat to the road safety. This article will discuss the merits and demerits of laying pipelines for urban gas pipelines, clarify the benefits of eliminating pipelines for overpasses, and summarize the measures for protecting gas pipelines in cities and towns.
