In the bridge overhaul project over the years has repaired a number of bridges, but there are still some unsolved. My team in the Beijing-Guangzhou line Baishui Bridge without interruption in the transport, do not repair the line conditions, lift the beam lift road 1.2 meters, to solve the problem of water damage. Now the construction method is as follows.
