简述供热管道无补偿直埋电预热施工技术

The technology of preheating of direct buried electric heating without compensation is described

介绍了无补偿直埋预热方式,结合古交兴能电厂长输供热管线实例,重点介绍供热管道敞槽预热敷设方式的基本原理,电预热技术、施工方法等及电预热技术的优势,大大降低了工程造价,节约投资。

This article introduced directly buried heating compensation,combined with the electrical factory of Gujiao Xingneng＇s long-range heat supply pipeline as an example,introduced the basic principle of heating pipe method of laying open slot preheating,electric heating technology,construction method and electric heating technology advantages,greatly reduces the project cost,save investment.
