陶瓷锚栓在防止轨道交通杂散电流腐蚀中的应用

Application of Ceramics Anchor Bolt in Rail Transit System to Prevent Stray Current Corrosion

针对地铁隧道潮湿环境和存在杂散电流的现状,结合国外已应用的新技术新材料,提出了新的解决方案,以解决相关设备遭受腐蚀的问题。杂散电流是一个不容回避的问题,要彻底解决也绝非易事。陶瓷锚栓作为解决地铁中杂散电流对设备造成腐蚀的方法,不仅可有效地保护相关的设备,而且带来了维护方面的便利和维护成本的降低,其全寿命成本大大低于采用普通锚栓。

Aiming at solving the current status of metro tunnel humid environment and the existence of stray current, by introducing the new technology and new materials adopted in foreign countries, a new solution is proposed to tackle with the problems of relevant device＇s corrosion. Stray current is a persistent problem uneasy to be solved completely, however, the application of ceramics anchor bolt could effectively prevent corrosion caused by stray current and protect the relevant devices and reduce the maintenance cost.
