隧道电缆桥架施工分析

高速公路的电缆桥架施工安装相对于一搬的普通建筑而言，不仅要求横平竖直，而且弯道也要求对称平滑。
一、高速公路电缆桥架的施工的一般程序：隧道电缆桥架施工准备，电缆桥架支架定位，电缆桥架支架安装，电缆桥架安装，支架的微调整。
二、电缆桥架安装施工准备：
（1）桥架支架的检查，电缆桥架厚度、宽度、是否符合要求，用镀锌检测仪检测电缆桥架涂层厚度。
三、电缆桥架的支架安装画线：
（1）对照图纸核对电缆桥架安装的位置和高度是否正确。
（2）如果是直线隧道，一般采用从中间向两边划电缆桥架安装线。
四、电缆桥架支架的安装微调。
（1）组装好电缆桥架支架。
 (2)测量要安装电缆桥架的隧道弧度。
（3）安装电缆桥架的托臂。
（4）封包电缆桥架托壁，防止高速公路隧道施工污染电缆桥架支架。
五、安装电缆桥架
根据不同的需求选择不同的电缆桥架。一般的电缆桥架长度为两米。
六、电缆桥架支架微调整。在安装的基础上轻微调整支架的位置，使得电缆桥架更加美观漂亮。

Analysis of the application of tunnel cable bridge

The construction and installation of cable tray for expressway is not only required for vertical and horizontal construction, but also symmetrical and smooth for corners.

First, the general procedures for the construction of the highway cable bridge: the construction preparation of the tunnel cable bridge, the positioning of the cable bridge bracket, the installation of the cable bridge bracket, the installation of the cable bridge, and the micro adjustment of the support.

Two. The installation and construction of cable bridge:

(1) the inspection of the bridge bracket, the thickness and width of the cable tray, and whether it meets the requirements, and the thickness of the coating of the cable bridge is detected by galvanizing detector.

Three. The drawing line of the bracket of the cable bridge:

(1) check the location and height of the cable tray installation correctly according to the drawings.

(2) if a straight tunnel is used, the cable bridge installation line should be drawn from the middle to the both sides.

Four. The installation of the cable bridge bracket is trimmed.

(1) assemble the cable bridge scaffold.

(2) measure the arc of the tunnel to be installed on the cable bridge.

(3) the installation of cable tray bracket.

(4) the supporting wall of the cable cable tray is to prevent the pollution of the cable tray support in the construction of the expressway tunnel.

Five. Installation of cable bridge

Select different cable tray according to different needs. The length of the general cable bridge is two meters.

Six, the cable bridge bracket micro adjustment. On the basis of installation, adjust the position of the bracket slightly, making the cable tray more beautiful and beautiful.
