地铁隧道内的电缆支架与疏散平台的金属构件易锈蚀、腐蚀。安装疏散平台与支架所需的种植螺栓材料是否合适,直接影响到隧道主体结构钢筋的电化腐蚀程度。文章阐述利用复合材料将疏散平台与部分电缆支架设计成一体化构件,较完善地解决了构件锈蚀问题,并最大限度地避免了杂散电流对隧道主体钢筋的电化腐蚀。 Subway tunnels within the cable support and evacuation platform metal components easy to rust, corrosion. Whether the planting bolting material needed for the evacuation platform and the support is suitable or not directly affects the galvanic corrosion of the reinforcement of the main structure of the tunnel. The article describes the use of composite materials to evacuate the platform and part of the cable bracket design into an integrated component, a more complete solution to the problem of corrosion components, and to maximize the stray current on the main body of the tunnel galvanic corrosion.
