Multifunctional Pedestrian Bridge Bailey Bridge/pedestrian Bridge Bailey Bridge

The inspection standards for Bailey bridge wind-resistant tie rods mainly include the following aspects:

1. **Assembly integrity**
- **Check whether the wind-resistant tie rods are fully assembled**: Ensure that the two wind-resistant tie rods set crosswise on each truss section have been correctly installed without omission.

2. **Length adjustment**
- **Check whether the tie rod length is correct**: The wind-resistant tie rod is equipped with a tensioning spiral buckle to adjust the tie rod length. There is a length indicator block inside the spiral buckle. When the spiral buckle is rotated until the rod end touches the length indicator block, it means that the tie rod length is correct.

3. **Fixed condition**
- **Check whether the locking nut is tightened**: There is a locking nut at one end of the spiral buckle to prevent the tie rod from loosening. When installing the tie rod, the locking nut must be tightened to ensure that the tie rod is firmly fixed.

4. **Appearance inspection**
- **Check whether the wind-resistant tie rod has any man-made damage**: Observe whether there are obvious signs of damage on the surface of the wind-resistant tie rod, such as bending, deformation or corrosion, which may affect its normal use.

5. **Looseness check**
- **Check if the wind-resistant tie rod is loose**: During the inspection, make sure that the wind-resistant tie rod is not loose, especially after heavy rain and other bad weather, the loose tie rod may not be able to effectively withstand the wind force.

6. **Function test**
- **Check if the wind-resistant tie rod can effectively withstand the wind force**: The main function of the wind-resistant tie rod is to withstand the lateral wind force perpendicular to the bridge to ensure the straightness and stability of the bridge. During the inspection, the function of the wind-resistant tie rod can be evaluated by simulating wind force tests or observing the performance of the bridge under actual wind force.

Through the above inspection, it can be ensured that the wind-resistant tie rod of the Bailey bridge is in good working condition, thereby ensuring the safety and stability of the bridge under wind force.
