1.通信、信号电缆可设在一个电缆槽内,也可以分设,但通信、信号电缆必须和电力电缆分槽敷设,如果分槽敷设有困难时,电力电缆可沿隧道墙壁架设,但应有必要的防护措施:
1. The communication and signal cables can be set in one cable trench or separately, but the communication and signal cables must be laid in separate trench with the power cables. If it is difficult to lay in separate trench, the power cables can be erected along the tunnel wall, but necessary protective measures shall be taken:
2.通信、信号电缆槽的弯曲半径不宜小于1.2m,电力电缆槽的弯曲半径通常为电缆外径的6~30倍3.槽底有高低差时,纵向应顺坡连接
2. The bending radius of communication and signal cable trough should not be less than 1.2m, and the bending radius of power cable trough is usually 6-30 times of the cable outer diameter. 3. When there is height difference at the bottom of trough, the longitudinal connection should be along the slope
4.电缆槽应设盖板,盖板顶面应与避车洞底面或道床顶面齐平,当电缆槽与水沟同侧并行时,应与水沟盖板齐平
4. The cable trench shall be provided with a cover plate, and the top surface of the cover plate shall be flush with the bottom surface of the refuge tunnel or the top surface of the track bed. When the cable trench is parallel to the same side of the ditch, it shall be flush with the ditch cover plate
电缆槽运输时，车厢底部、四周及两层板块之间应铺设一层草帘或其他缓冲物，防止运输中边角磕碰、磨损。车厢底部应保持平坦。设法使成品固定。运输中，板块必须立方靠近挤实，防止串动或碰撞。应采用机械兜底装卸、搬运，严禁抛掷。堆放场地必须坚实平坦，产品堆放时立方、紧贴、倾斜度大于15度，底部和层与层之间用小方木进行隔垫。
During the transportation of cable trough, a layer of straw curtain or other buffers shall be laid at the bottom, around and between two layers of plates to prevent collision and abrasion of edges and corners during the transportation. The bottom of the car should be flat. Try to fix the finished product. During transportation, the plates must be compacted close to each other to prevent movement or collision. Loading, unloading and handling shall be carried out by mechanical pocket bottom, and throwing is strictly prohibited. The stacking site must be solid and flat. When stacking products, they shall be cubic, close and inclined more than 15 degrees. The bottom and between layers shall be padded with small square wood.
