蒸汽直埋管道的安全与节能技术近年来日趋成熟,但在南方高水位城市应用中还存在诸多缺陷。本文结合工程实践,针对这些缺陷进行了技术改进,并在多项工程中推广应用,取得了良好的效果。 In recent years, the safety and energy saving technologies of steam buried pipes have become more and more mature, but there are still many shortcomings in the application of the high water level cities in the south. Based on the engineering practice, this paper has made technical improvements to these defects and popularized them in many projects and achieved good results.
