摘要
结合现行标准规范和相关规定,对城市综合管廊天然气管道的敷设进行探讨,包括天然气管道安全间距的确定原则、与重要公共设施的安全间距、与地铁隧道的安全间距、进排气口高度、独立设舱、舱位设置、本质安全设计等方面。分析需要进一步研究的问题,包括廊体抗震设计、管廊本体和市政管线同步设计与同步建设、完全独立舱室、与其他管线舱室共享排水泵等。
Combined with the current standards and relevant regulations, the laying of natural gas pipe-line in urban utility tunnel is discussed, including the principles for determining the safety distance of natural gas pipeline, the safety distance to major public facilities, the safety distance to subway tunnel, the heights of air inlet and outlet, independently setting of compartment, setting of compartment space, intrinsically safe design and other aspects. The issues that need to be further studied are analyzed, including the seismic design of the tunnel body, the synchronous design and construction of the compartment body and municipal pipelines, the completely independent compartment, sharing drainage pump with other pipeline compartments and other aspects.
