When building a 321-type Bailey bridge in mountainous areas, it is crucial to ensure that the bridge base is stable. Here are some specific methods and precautions:
1. **Foundation bearing capacity inspection**
- **Soil condition assessment**: Before building a Bailey bridge, the soil conditions at the bridge base must be assessed to ensure that the soil is solid. If the soil bearing pressure does not meet the design requirements, the foundation under the bridge base must be expanded or reinforced.
- **Angle of repose pile setting**: When the bank slope is steep (greater than the angle of repose), the position of the angle of repose pile must be calculated and set according to the formula.
2. **Foundation reinforcement method**
- **Enlarge the foundation**: If the soil conditions are not good, the bearing capacity can be increased by expanding the foundation area.
- **Concrete reinforcement**: Pour the concrete foundation at the bridge base to ensure that the foundation is deep into the stable stratum and provides sufficient support.
- **Pile foundation reinforcement**: When necessary, the method of driving pile foundation can be used to enhance the stability of the foundation.
3. **Bridge seat design and construction**
- **Bridge seat axle beam**: The bridge end column is supported on the bridge seat axle beam, which is divided into multiple sections. The appropriate bridge seat is selected according to the number of bridge rows.
- **Seat plate setting**: The seat plate should be set at the seat plate axis position, and the seat plate position should be properly excavated to reduce the bridge deck elevation, generally making the height difference between the bridge deck and the road surface no more than 30 cm.
4. **Precautions during construction**
- **Construction personnel safety**: Construction personnel must wear safety helmets and safety belts, and it is strictly forbidden to work on the rack after drinking. When using a crane to lift and remove Bailey piers, a special person should be assigned to direct the crane, and it is strictly forbidden for the crane boom to collide with the Bailey beam and its foundation.
- **Roller setting**: Rollers are set at the marked roller position, and a sample plate should be placed underneath. Only one row of trusses is allowed to pass through each rock, and the distance between the rock and the bearing plate is about 1.0 meter, and at least not less than 0.75 meter.
Through the above measures, the stability of the bridge base foundation can be ensured when building a Type 321 Bailey bridge in mountainous areas, thereby ensuring the safety and stability of the bridge.
