1)弹线定位:根据设计图纸确定桥架走向,从始端至终端找好水平线或垂直线,用粉线袋在线路的中心外进行弹线,按照设计图要求及施工验收规范规定,分别找出分线盒、分线口及支架的具体位置,用铅笔分别标注。一般支架间距为1.0-1.5m。
1) Snap line positioning: determine the direction of the bridge according to the design drawings, find the horizontal line or vertical line from the beginning to the end, snap the line outside the center of the line with a powder bag, find out the specific positions of the junction box, junction opening and support respectively according to the requirements of the design drawings and the provisions of the construction acceptance specifications, and mark them with pencils. Generally, the spacing between supports is 1.0-1.5m.
2)桥架敷设:根据标准位置放置分线盒和支架,然后放置桥架和出线口,同时根据需要加各种配件,朝上的桥架不必立得太长,否则易被砸断。连接完毕后,调整支架和塑料盖,使出线口到适当高度。达到位置正确,固定牢固,走向合理。桥架水平或垂直敷设部分平直度和垂直度允许偏差不超过5mm。为防止灰浆进入,各连接处周边抹专用胶,各分线盒、出线口盒盖拧紧,并用铁丝绑扎,未端加塑料封堵。浇筑混凝土时设专人看护,发现问题及时处理。
2) Cable tray laying: place the junction box and support according to the standard position, and then place the cable tray and outlet. At the same time, add various accessories as needed. The upward cable tray does not have to stand too long, otherwise it is easy to be broken. After the connection, adjust the bracket and plastic cover to make the outlet to a proper height. The position is correct, the fixation is firm, and the direction is reasonable. The allowable deviation of straightness and verticality of the horizontal or vertical laying part of the bridge shall not exceed 5mm. In order to prevent mortar from entering, the periphery of each connection is smeared with special glue, the covers of each junction box and outlet box are tightened, bound with iron wire, and the end is blocked with plastic. When pouring concrete, special personnel shall be assigned to take care of it, and problems found shall be handled in time.

3) Welding of jumper wire: determine the specification of jumper wire according to the construction specification. The welding surface at both ends of the ground wire shall not be less than 6 times the cross-section of the jumper wire, and the weld shall be uniform and firm.
4)槽内配线:先清扫桥架,可先将带线穿插至出线口,然后将布条绑在带线一端,从中一端将布线条拉出,反复多次可将山东桥架内的杂物和积水清理干净,也可用空气压缩机将桥架内的杂物和积水吹出。放线前应先检查管及桥架连接处的护日是否齐全。
4) Wiring in the groove: first clean the bridge, insert the belt line to the outlet, then tie the cloth strip to one end of the belt line, pull out the cloth strip from the middle end, and repeatedly clean up the sundries and ponding in Shandong bridge, or blow out the sundries and ponding in the bridge with air compressor. Before setting out, check whether the day protection at the connection of pipe and bridge is complete.
5)线路检查及绝缘遥测可参照管内穿绝缘导线安装工程的相关部分。
5) For line inspection and insulation telemetry, please refer to the relevant parts of the installation project of insulated conductor passing through the pipe.
6)面板安装:配合装修,依据各出线口用途,安装相应的面板。
