通过对丹东市供热现状、供热规划的分析以及对大管径供热管道应力的计算与校核,从理论上分析,无补偿直埋冷安装技术对于丹东市极大多数供热管网,在设计角度来讲是完全可行的。并结合部分城市的实际应用,对此项技术在设计、安装过程中应注意的问题进行阐述,同时考虑其投资少;施工周期短;运行安全、可靠等诸多优势,无补偿直埋冷安装技术势必要在未来的城市建设中发挥重要的作用。因此,大力推广此项技术,使其尽早的运用到丹东市的热网建设中会对丹东市的发展有着深刻的意义。
Through the analysis of the current situation of heating in Dandong City, heating planning and the calculation and verification of the stress of heating pipe with large diameter, from the theoretical analysis, the technology of direct buried cold compensation without compensation is of great significance to Dandong City’s vast majority of heating pipe networks , In terms of design is entirely feasible. Combined with the practical application in some cities, the problems that should be noticed in the design and installation of this technology are described, taking into account its low investment, short construction period, safe and reliable operation and many other advantages. It is bound to play an important role in the future urban construction. Therefore, vigorously promote this technology to make it as soon as possible to the construction of thermal network in Dandong Dandong City, the development will have profound significance.
