安裝橋架在以下這些情況下是需要加設保護罩的，玻璃鋼橋架在戶外安裝時，其更上層或每一層。玻璃鋼橋架在鐵算子板或相類似的帶孔裝置下安裝時，其更上層橋架應加保護罩，如果更上層玻璃鋼橋架寬度小于下層的橋架寬度時，下層橋架亦加保護罩。

Installation of the bridge in the following circumstances is required to install protective cover, FRP bridge in outdoor installation, its top or each layer. When a FRP bridge is installed under an iron operator plate or a similar device with holes, the upper deck of the FRP bridge should be protected.

Fiberglass reinforced plastic (FRP) cable bridge is erected vertically within 2 m from the ground level. Fiberglass reinforced plastic (FRP) bridge frames are installed in places susceptible to mechanical damage of pneumatic ball valves. Fiberglass reinforced plastics (FRP) bridge frames are installed in dusty places. In places with special requirements, protective covers should also be installed for FRP bridge erection.

此外，橋架的安裝高度可在2.2-2.8米范圍內可調，選擇2.2米時應防止人為拆除破壞，選擇2.8 米時注意通風管等其他物品影響視頻探測器視野。安裝支架水平距離車位線可在3-4米范圍內可調，雙車位時候選擇行車道（寬度）中間位置。

In addition, the installation height of the bridge can be adjusted in the range of 2.2-2.8 meters. When choosing 2.2 meters, man-made demolition and destruction should be prevented. When choosing 2.8 meters, attention should be paid to ventilation ducts and other items affecting the visual field of video detectors.
