燃气管道跨越河道施工方法的比选及应用

近年来,随着天然气行业的快速发展,城市管网的覆盖越来越广,因此燃气管道敷设不可避免地要跨越河流。简要介绍了架空跨越河道敷设燃气管道随桥架设和管桥架设两种施工方法的适用条件和优缺点,并以工程实例具体分析了在实际施工中的重点和难点,为今后类似施工提供了借鉴。

Comparison and Application of Construction Methods for Gas Pipeline Crossing River

In recent years, with the rapid development of natural gas industry, the coverage of urban pipe network is becoming wider and wider, and the laying of gas pipeline will inevitably face crossing rivers. This paper briefly introduces the applicable conditions, advantages and disadvantages of two construction methods of laying gas pipeline overhead across river(erection method with bridge and pipe bridge method).The key and difficult processes of these two crossing construction methods in actual construction are analyzed with engineering examples, which can be referred to for other similar works in the future.
