影响地铁施工的电力线路迁改设计研究

Relocation design of power line affecting metro construction

在调查国内地铁施工管线迁改现状的基础上,分析了影响地铁施工电力线路的不同种类和敷设形式。根据地铁工程施工中的土建结构形式,归纳了电力线路的迁改类型。在综合考虑实施难易程度及工程投资因素的基础上,提出采取保护形式和迁改形式的设计思路。结合电力线路工程特点,研究电力线路保护和迁改的实施方案,并按迁改实施步骤出发,探索电力线路迁改与保护的阶段性设计要点和工程措施。

Based on the investigation of the current situation of pipeline modification in metro construction, this paper analyzes different types and laying forms of power lines affecting metro construction. Based on the civil structure forms in the construction of metro projects, it summarizes the types of power line modification. Considering comprehensively the difficulty of implementation and the factors of the project investment, this paper puts forward the design concept by using the form of protection and modification. With the characteristics of power line engineering works, it studies the implementation scheme of power line protection and relocation, and explores the staged design key points and engineering measures of power line relocation and protection in line with the implementation steps of relocation.
