What Should Attention Be Paid To The Bridge Straddle

1. An operator is assigned at the launching point of the bank rock of the Beret piece to check at any time whether there is a failure of the rock in the launching process and whether the bridge is blocked or deviated; Solve the problem in time, suspend the rollout when necessary, and use a jack to partially lift the bridge and move the roller.
2. Strictly control the speed of pushing and pulling, force should be uniform, push should be slow and smooth, not too fast or too fast.
3. A person should also be assigned to the rock on the other side of the Berei Patch. The task is to assist the guide beam to accurately fall on the rock; If offset, the rock can be moved or the guide beam can be moved to attach the guide beam to the rock.
4. Check the direction of push out at any time. This can be corrected by flipping the tail.
5. When the opposite bank is lower than the push-out bank, control cables can be placed on both sides of the push-out bank truss to control the push-out speed and avoid slipping into the river and causing accidents.
6. Entrance and exit construction After the bridge is in place, the entrance and exit can be constructed. The longitudinal slope of the inlet should not be too large. Since the roadway surface is 79cm higher than the ground, the foundation should be excavated, the bridge deck elevation should be lowered, and the entrance and exit should be kept as gentle as possible.
