天然气管道穿越高速公路的方案设计

Scheme Design of Natural Gas Pipeline Crossing Expressway

“十四五”是中国能源转型发展的关键时期,碳达峰、碳中和目标对能源领域提出更高要求。在未来相当长一段时期内,天然气消费将快速增长。目前,中国各地都在加快天然气主干管网建设,实现国家干网、省级干网与支线互联互通。中国在推进天然气建设的同时,天然气管道难免与高速公路存在交叉情况,文章以安徽省天然气管道顶管穿越高速公路方案设计为例,进行分析研究,提升优化天然气管道穿越高速公路的设计方案。

The“14th Five-Year Plan”is a key period for China’s energy transformation and development,and the goal of reaching the peak of carbon and carbon neutrality puts higher requirements on the energy f ield.In the future for a long period of time,natural gas consumption will grow rapidly.At present,all parts of China are speeding up the construction of natural gas main pipeline networks to realize the interconnection of national dry networks,provincial dry networks and branch lines.In the process of promoting the construction of natural gas in China,it is inevitable that natural gas pipelines will cross with expressways.This paper takes the project design of natural gas pipeline jacking through expressways in Anhui Province as an example to carry out analysis and research,and improve and optimize the design scheme of natural gas pipeline crossing expressways.
