供热热水管道管廊敷设方式研究进展

Recent Progress of Tunnel Laying Method on Heating Pipeline

综述热水管道传统敷设方式现状,对管廊热水管道的现行敷设方式及存在的主要问题进行探讨.依据热水管道有补偿直埋敷设向无补偿冷安装直埋敷设的研究进展,提出管廊热水管道无补偿架空敷设方式,取消补偿器的设置,增加管网运行安全性与可靠性.分析管廊热水管道无补偿架空敷设可能存在的主要问题,提出管廊热水管道无补偿敷设的理论与工程设想解决方案.

The current situation of laying heating pipeline in traditional ways was reviewed,and several major problems of current laying method were discussed in this paper.In order to cancel the compensator and enhance the running safety and reliability of the whole network,the method of laying heating pipeline without compensation in the utility tunnel was put forward;according to the progress of transforming from directly buried hot water pipe with compensation to the one without compensation.In addition,taking potential problems of overhead laying freecompensation hot water pipeline in the utility tunnel into consideration,the theory and engineering ideas for the freecompensation installation mode of hot water pipeline in the utility tunnel were proposed.
