隧道電纜橋架施工分析

高速公路的電纜橋架施工安裝相對于一搬的普通建筑而言，不僅要求橫平豎直，而且彎道也要求對稱平滑。
一、高速公路電纜橋架的施工的一般程序：隧道電纜橋架施工準備，電纜橋架支架定位，電纜橋架支架安裝，電纜橋架安裝，支架的微調整。
二、電纜橋架安裝施工準備：
（1）橋架支架的檢查，電纜橋架厚度、寬度、是否符合要求，用鍍鋅檢測儀檢測電纜橋架涂層厚度。
三、電纜橋架的支架安裝畫線：
（1）對照圖紙核對電纜橋架安裝的位置和高度是否正確。
（2）如果是直線隧道，一般采用從中間向兩邊劃電纜橋架安裝線。
四、電纜橋架支架的安裝微調。
（1）組裝好電纜橋架支架。
 (2)測量要安裝電纜橋架的隧道弧度。
（3）安裝電纜橋架的托臂。
（4）封包電纜橋架托壁，防止高速公路隧道施工污染電纜橋架支架。
五、安裝電纜橋架
根據不同的需求選擇不同的電纜橋架。一般的電纜橋架長度為兩米。
六、電纜橋架支架微調整。在安裝的基礎上輕微調整支架的位置，使得電纜橋架更加美觀漂亮。

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.
