The high voltage cable and the weak current cable tray vendors in the bridge bridge share one bridge

When people are installing objects, they will inevitably make some mistakes.
So, what are the ways to prevent frequent mistakes in the installation of bridges?
Next, the cable tray manufacturer will introduce to you.
The main results are as follows:
The bridge deck is not well treated with corrosion and poor appearance.
The bolts and nuts at the connection of the bridge plate are on the inside.
The high voltage cable and the weak current cable tray vendors in the bridge bridge share one bridge.
The cables in the bridge are arranged out of order, and there is a phenomenon of twisting.
There are too many cables in the bridge, more than 40% of the net surface of the power cable and 50% of the control cable.
The distance of the bridge support is long (1.5-3m), which is not one section and two supports, there are more deformation, more hanging bars, less fixed support, and can not bear horizontal force; the straight line length of the bridge is more than 30m (steel) (aluminum 15m) without expansion joints.
There are no compensation measures for bridge frames and cables to cross deformation joints.
The cable in the bridge tray is unmarked (entrances and corners and branches).
The cable in the bridge is not firmly fixed, and some are not fixed (especially in the vertical bridge).
Bridge and other pipes, especially heating and air conditioning pipes, are too close to meet the requirements; general pipes 0.4m (parallel), 0.3m (crossing); thermal insulation pipes 0.5m (parallel), 0.3m (crossing); non-thermal insulation pipes 1.0m (parallel), 0.5m (crossing).
There is no spanning at the joint of the non-galvanized steel bridge, or the spanning is poor or the appearance is poor.
Bridge and distribution boxes, plates, cabinets, etc., have no span grounding, and the number of bridge brackets is less than 2.
At the joint of the cable tray vendors plate, the galvanized steel plate does not have two bolts as anti-loosening nuts or washers, which does not meet the requirements.
