What should be paid attention to across the bridge?

1. One operator is assigned beside the shoreline rock to check whether the rock is faulty at any time, whether bailey bridge is blocked or there is deviation in the process of pushing out; If the problem is found, it should be dealt with in time. When necessary, it should be suspended to push out. The bridge should be jacked partially by the jack and the roller should be moved.

2. Strictly control the speed of push and pull, force should be uniform, push out to be slow and steady, do not too fast.

3. Panel for bailey bridges across the rock should also designate a person responsible for its task is to assist the guide beam accurately fall on the rock; If offset, can move the rock or toggle the guide beam, so that the guide beam on the rock.

4. Check the pushing direction at any time, and correct the deviation immediately if found, especially when the truss is pushed close to the equilibrium point, it is easier to turn, at this time, it can be corrected by pulling the tail.

5. When the opposite shore is lower than the pushing bank, control cables can be set on both sides of the pushing bank truss to control the pushing speed and avoid sliding into the river to cause accidents.

6. Build the entrance and exit bridge is located in place, can build the entrance and exit. The vertical slope of the entrance and exit should not be too large. Because the roadway surface is 79 cm higher than the ground, the foundation should be excavated normally, the elevation of the bridge deck should be lowered, and the entrance and exit should be maintained as far as possible.

7. When the height difference between the bridge deck and the road surface is less than 15 cm, a slab can be set. One end of the board shall be placed in the clasp of the beam, and the other end shall be placed on the road, but the sleepers shall be placed under it. The length of sleepers is the same width as the entrance and exit, and can also be replaced by bridge slabs. When the height difference between the bridge deck and the road surface is 15~30 cm, two slabs should be installed.
