4)強(qiáng)電和弱電電纜。如受條件限制需安裝在同一層橋架上時(shí)，應(yīng)用隔板隔開。

4) Strong and weak current cables. If it is required to be installed on the same level of bridge due to limitations, partitions should be used to separate it.

九、不銹鋼橋架與各種管道平行或交叉時(shí)，其凈距應(yīng)符合表DQ4-1的規(guī)定。

9、 When stainless steel cable trays are parallel or cross with various pipelines, their clear distance should comply with the provisions of Table DQ4-1.
