In order to ensure the construction and future use quality of cable bridge, Shandong cable bridge has strict operation rules in installation and grounding.

（1）电缆桥架装置前，与土建及水暖、通风空调谐和，肯定与通风管、水道管之间的穿插配合问题。依照电让水的准绳，电气管道在上面、水管在下面，桥架处于高点，其次为风管、上、下水管，当部分不能满足请求时需加防水措施。

(1) Before cable bridge erection, first of all, it should be in harmony with civil engineering, water heating, ventilation and air conditioning specialty, and affirm the problem of interpolation and coordination with ventilation pipe and waterway pipe. According to the criterion of electric transfer water, the electrical pipeline is above and the water pipe is below, the bridge is at the top, followed by the air pipe, the upper and the sewer pipe. When some of them can not meet the requirements, waterproofing measures should be added.

（2）先停止放线定位，装置立柱、吊支架等，然后停止托臂装置，托臂与吊支件之间运用专用衔接片固定，以保证支架与桥架本体之间坚持垂直不会受重力作用发作倾斜下垂；再装置桥架本体，桥架本体应运用衔接板衔接结实，并用固定螺栓将桥身固定在托臂上。

(2) First stop setting-out and positioning, install pillars, suspension brackets, etc., then stop brackets, and fix brackets and suspension brackets with special connectors, so as to ensure that the brackets and suspension brackets are perpendicular to each other and will not be inclined and droop under the action of gravity; then install the main body of the bridge, which should be connected and consolidated by professional connector plates, and fix the bridge body with professional fixing bolts. On the bracket.

（3）先装置电缆桥架直线段及弯通、三通等常规附件，然后现场丈量各种特殊外形的弯通、非规范件，并及时把外形尺寸提供应消费厂家，再由消费厂家停止工厂化加工，保证工程装置质量；电缆桥架的装置必需结实牢靠，横平竖直，无扭曲变形，内壁无毛刺，附件齐全。

(3) Firstly install the cable bridge straight section, bending, tee and other conventional accessories, then measure the bending and non-standard parts of various special shapes on the spot, and provide the shape dimensions to the consumer manufacturer in time, then stop the factory processing by the consumer manufacturer to ensure the quality of the engineering device; the cable bridge device must be firm, horizontal and vertical, without distortion, without burrs on the inner wall, and attachment. Complete pieces.

（4）电缆桥架直线段衔接采用衔接板，用垫圈、弹簧垫圈、螺母紧固，接口缝隙紧密平齐，槽盖装上后平整，无翘角，出线口的位置精确。

(4) Connection plate is used to connect the straight line segment of cable bridge frame, which is tightened by gaskets, spring washers and nuts. The joint gap is tightly and smoothly. After the slot cover is installed, it is flat, without warping angle, and the outlet position is accurate.

（5）电缆桥架在干线、支线、拐弯、进出接线箱的应用专用附件停止施工，其附件应与桥架材质相同。桥架底、盖与各种附件相对接时，接缝处应采用抱脚衔接，并用螺丝紧固，应严实平整、固定结实；桥架各种附件的固定点不应少于两点。

(5) The construction of cable bridge frame shall be stopped by using special accessories in the center of trunk line, branch line, bend and access box. The accessories shall be of the same material as the bridge frame. When the bottom and cover of the bridge are connected with various accessories, the joints should be connected by holding feet and fastened by screw, which should be tightly flat and fixed, and the fixed points of all kinds of accessories of the bridge should not be less than two points.

（6）桥架的终端应采用专用的终端头封堵。

(6) The terminal of the bridge shall be blocked by a special terminal head.

（7）在线路分支接头处应采用相应接线箱。

(7) Corresponding wiring boxes should be used at the branch joints of the lines.
