地铁隧道内机械敷设电缆方法实践

Practice of Mechanical Cable Laying Method in Subway Tunnel

针对地铁隧道空间小、大截面电缆不易弯曲(电缆本体重、外径大)、人工敷设效率低、施工组织困难,施工质量和安全控制效果差的实际情况,在西安地铁二号线的环网电缆敷施工展开时,提出采用机械敷设电缆的方法,在全面提高安全保证的前提下,极大地提升了电缆敷设质量,减轻了作业人员劳动强度,显著提高了作业效率,取得了成效。

The subway tunnel with small space, large cross-section cable （cable is not easy to bend the body weight, diameter）, artificial laying low efficiency, construction difficult, the actual situation of the construction quality and safety control of expansion loop network, cable laying construction in Xi＇an metro line two, the paper puts forward the method of Mechanical cable laying, on the premise of improving safety, which greatly improved the quality o fthe cable laying, reducing the labor intensity of workers, improves the work efficiency, achieved results.
