城市燃气管道入综合管廊的应用分析及技术探讨

Applied Analysis and Technical Discussion on Installation of Natural Gas Pipeline in Utility Tunnel

近年来综合管廊的建设快速发展,如何提高燃气管道入综合管廊的技术水平是目前推动综合管廊长远发展的关键点。本文首先分析了燃气管道入廊的优缺点、国内外现状及相关设计经验,从如何有效防止泄露、发生泄露时如何有效防止爆炸两方面对燃气管道入廊的技术要点进行探讨,并提出了相应技术方法。

With the rapid development of the construction of the utility tunnel, the key point of promoting long-term development of the utility tunnel is how to improve the technical level of installation of natural gas pipeline in utility tunnel. To begin with, advantages and disadvantages, domestic and overseas status, as well as related design experience were introduced in this paper. Then, keynotes of design technique were discussed on how to prevent gas leakage and avoid gas explosion effectively alter detecting the leakage, and the corresponding technical methods were put forward to deal with those problems.
