Heroes behind us for city's beauty
CHONGQING (CQNEWS) -- The brilliance of the bridge is like the soul the night view of Chongqing, but the people who put on the “neon clothes” for the bridges quietly exit as the night falls. They are seldom noticed because they are always "above the ground" and climb towering bridges to maintain lighting systems. They are the pursuers of Spider-Man and the guardians of this beautiful city.
Vehicles traffic on Caiyuanba Yangtze River Bridge, but few people notice the Spider-Man wearing orange clothes climbing the high bridge, they are the electricians who maintain the lighting system of the bridge. The lighting system of 14 river-crossing bridges of Chongqing is maintained by 34 municipal electricians, who are divided into five teams and on duty 24 hours in turn.
At least four electricians are required for each bridge lighting maintenance task. Two of them are responsible for operating high above the ground, one is responsible for safety monitoring, and the other is responsible for other related matters on site. Before each aerial operation, the electrician will carefully check all kinds of tools.
There are two major difficulties in bridge lighting maintenance. One is to work high above the ground, the distance from the top of the bridge to the river surface is often more than 100 meters, and the operation risk coefficient is high. In addition, each bridge has an independent lighting control system, which makes the lighting lines complex and maintenance difficult.
According to different structures of bridges, lighting fixtures are also different. There are 5660 lights on Caiyuanba Bridge, which are divided into balustrade lamp, projection lamp, digital display lamp on cable, wall-washing lamp at bridge arch and high-power wall-washing lamp at bridge abdomen.
The biggest difficulty is the high-power wall-washing lamp at the bridge abdomen. It is necessary to suspend the electrician to three meters below the bridge, and then fix a professional support similar to pipeline on the bridge abdomen. The electrician has to climb on the bridge abdomen through the support for maintenance.
The orange overalls of the electricians are made of cotton in order to prevent sparks from rapid burning during operation. Because of the high temperature in summer, electricians choose to wear rattan safety helmet to make it more ventilated and breathable.
In charge of bridge lighting maintenance, it is also a job of "observing the weather". They should always pay attention to the weather forecast. Electricians are not allowed to work in order to ensure safety in extreme weather such as heavy rain and strong winds.
As night falls and the lights begin to shine, bridges across the Yangtze River shine brightly, making the city more dazzling. The silent insistence of municipal electricians, leaves the brilliance to the city and the shadow to themselves. (Translated by Luo Juan, Fathom Language Limited)
