      电缆输送机水下施工工作开始前，先检查所敷设电缆是否符合规格要求，检查电缆芯线是否进水受潮，是否有机械损伤，所需的各种材料、工器具是否合格、齐全。各项工作准备就绪，将电缆输送机到工作现场。以电缆沟敷设方式为例，先检查电缆沟是否按图挖好，电缆井砌砖抹灰，沟内杂物清理干净，排水是否通畅，电缆沟电缆支架是否牢靠，接地线是否全程联通，完毕后根据设计图纸和现场情况决定电力电缆走向，丈量电缆路径长度。
      根据路径长度来截电力电缆，一般要留有3~5m 的余度；在敷设电缆时要注意，动力电缆，通信电缆，信号电缆在电缆沟层次要分明，一般动力电缆放在电缆沟最下一层，这样依次排列，电缆尽量摆放平整，少交叉。最后就是盖好电缆盖板。

Before the start of construction work, check the cable laying conformed to the specification requirements, check whether the cable core is water be affected with damp be affected with damp, whether to have mechanical damage, the required qualified whether various materials, instruments and complete.Each work is ready, the power cable to the job site.Cable conduit installation, for example, first check whether the cable trench is according to the figure to dig well, cable pit brick and plaster, ditch cleaning to clean, whether the drainage unobstructed, whether in cable trench and cable bracket, grounding line, whether the whole unicom finished according to the design drawing and site situation decision power cable, cable path length measurement.According to the path length cut power cable, generally should have 3 ~ 5 m redundancy;Should pay attention to when laying cable, power cable, communication cable, signal cable in the cable trench level to clear, general power cable in the cable trench the next layer, lined up like this, cable put flat, as far as possible little cross.Finally, cover the cable cover plate.
