(2) When two groups of cable trays are laid in parallel at the same height, the clear distance between them shall not be less than 0.6m. (4) When the route of the bridge is drawn on the parallel diagram, the coordinates or positioning dimensions and elevations of the starting point, end point, turning point, branch point and lifting point of the bridge shall be indicated. If the axial side diagram of bridge laying can be drawn, the material statistics will be more accurate.

直线段：注明全长、桥架层数、标高、型号及规格。拐弯点和分支点：注明所用转弯接板的型号及规格。升降段：注明标高变化，也可用局部大样图或剖面图表示。

Straight line section: indicate the total length, number of bridge layers, elevation, model and specification. Turning point and branch point: indicate the model and specification of the turning adapter used. Lifting section: the elevation change can also be indicated by local detail drawing or section drawing.

（3）桥架支撑点， 如立柱、托臂或非标准支、构架的间距、安装方式、型号规格、标高，可同意在平面上列表说明，也可分段标出用不同的剖面图、单线图或大样图表示。

(3) The spacing, installation mode, model, specification and elevation of bridge support points, such as columns, corbels or non-standard supports and frames, can be listed on the plane, or marked in sections and represented by different section drawings, single line diagrams or detail drawings.

（4）电缆引下点位置及引下方式，一般而言，大批电缆引下可用垂直弯接板和垂直引上架，少量电缆引下可用导板或引管，注明引下方式即可。

(4) Generally speaking, a large number of cables can be led down with vertical bending plate and vertical lead-in frame, and a small number of cables can be led down with guide plate or lead pipe, indicating the lead-down method.

（5）电缆桥架宜高出地面2.2米以上，桥架顶部距顶棚或其它障碍物不应小于0.3米，桥架宽度不宜小于0.1米，桥架内横断面的填充率不应超过百分之50。

（6）电缆桥架内缆线垂直敷设时，在缆线的上端和每间隔1.5米处应固定在桥架的支架上，水平敷设时， 在缆线的首、尾、转弯及每间隔3~5米处进行固定。

(6) When the cable in the cable tray is laid vertically, it shall be fixed on the support of the cable tray at the upper end of the cable and at an interval of 1.5m. When laying horizontally, it shall be fixed at the head, tail, turn and at an interval of 3 ~ 5m.

（7）在吊顶内设置时，槽盖开启面应保持80毫米的垂直净空，线槽截面利用率不应超过百分之50。

(7) When set in the ceiling, the opening surface of the slot cover shall maintain a vertical clearance of 80mm, and the utilization rate of the section of the trunking shall not exceed 50%.

（8）布放在线槽的缆线可以不绑扎，槽内缆线应顺直，槽内缆线应顺直，尽量不交叉，缆线不应溢出线槽，在缆线进出线槽部位， 转弯处应绑扎固定。垂直线槽布放缆线应每间隔1.5米固定在缆线支架上。

(8) The cables laid in the trunking may not be bound. The cables in the trunking shall be straight, and the cables in the trunking shall be straight without crossing as far as possible. The cables shall not overflow the trunking. The cables shall be bound and fixed at the places where they enter and leave the trunking and at the corners. Cables laid in vertical trunking shall be fixed on the cable support at an interval of 1.5m.

（9）在水平、垂直桥架和垂直线槽中敷设线时，应对缆线进行绑扎。4对线电缆以24根为束，25对或以上主干线电缆、光缆及其它信号电缆应根据缆线的类型、缆径、缆线芯数分束绑扎。绑扎间距不宜大于1.5米，扣间距应均匀，松紧适度。
