青岛电力工程中非开挖技术的应用

The Uses of No-Excavate Technique in Qingdao Power Project

非开挖技术是近几年来发展起来的一种市区敷设管道的先进市政施工技术，该文阐述了非开挖工艺特点、设备组成及设计与施工方式、管材连接及安装，同时进行了开挖和非开挖工期比较、经济性分析，认为目前在青岛市区进行大规模电力管线施工的情况下，为了防止市政工程二次开挖达到保护市容环境的目的，采用非开挖技术施工势在必行。

No-excavate technique is a new kind of pipeline laying method which is used in municipal construction. The technique characteristics of no-excavate, equipment, methods of construction and connection of pipeline were mentioned in this paper, on the other hand, the construction methods and economic analyze were compared between no-excavate technique and excavate technique. Considering that large scale of power pipeline construction are processed now, in the purpose of protect environment and prevent second-excavate, the no-excavate technique is the best way to adopt.
