城市轨道交通屏蔽门绝缘地坪施工方案的研究

Study on the Construction Scheme of Platform Screen Door Insulation Floor in Urban Rail Transit

在已实施的国内轨道交通项目中,站台屏蔽门的绝缘地坪工艺及施工方法理论上可行,但在施工完成后或设备运营后受多种因素影响易发生绝缘电阻值下降甚至失效的问题。为解决上述问题,我们对国内几种使用较为广泛的有轨道交通安装、运营实例的屏蔽门绝缘地坪方案进行了试验,得出了绝缘地坪性能数据,推荐出几种可靠的方案,为相关工程的设计与施工提供一定的参考。

With the development of traffic, we found that in the completed mass transit projects, the technique and construction method of the insulation floor of the platform screen door are feasible in theory, but the insulation resistance is easy to decline or even fail after the construction or operation, due to many factors. To solve the above problems, we test some schemes of the insulation floor of the platform screen door which are widely used in China, and have installation and operation experience, and obtain their performance data. This paper recommends several reliable solutions for related engineering design and construction for reference.
