Why did this bridge start the biggest renovation?
The deck area of Haicang Bridge is 30,000 square meters, and new modified asphalt will be replaced on the 25th.
This is the biggest renovation since the completion of the bridge, because it is really necessary.
People who pass by Haicang Bridge every day will feel that there are potholes on the deck. If it rains, there are often many large puddles on the bridge deck.
Professionals explained that Haicang Bridge is a steel box girder bridge, and the steel plates are paved with asphalt. The steel plate is very smooth, and the asphalt will not completely bite on the steel plate after a long time.
The puddle in rainy days is mainly caused by the aging and shedding of asphalt after it reaches its service life. After the vehicle is crushed, it is difficult to stick back in rainy days like during the day, and pebbles are scattered to form puddles. Considerable traffic volume is also a cause of bridge deck asphalt damage.
The design capacity of Haicang Bridge is 50,000 vehicles per day (two-way). In fact, the capacity of Haicang Bridge has reached1.4000 vehicles/day.
But professionals say that the pit on the bridge deck does not affect safety. This is the asphalt layer on the bridge steel plate. The whole steel box girder structure of the bridge is under asphalt, and the surface potholes have no influence on the overall safety of the bridge.
According to national standards, the health status of bridges can be divided into five categories, one is new bridges and the other is dangerous bridges. 20 1 1 year test results show that Haicang Bridge is rated as a second-class bridge, which is very good. Level.
