Suspension Bailey Bridge/prefabricated Compact Bailey Bridge
When reinforcing Bailey bridges in mountainous areas, construction safety is of vital importance. Here are some key safety considerations and measures:
1. **Preparation before construction**
- **Geological survey**: Before construction, a detailed survey of the geological conditions in the mountainous area should be conducted to ensure the rationality of the foundation treatment plan.
- **Special construction plan**: Prepare a special construction plan including design, assembly, dismantling, etc., and clarify safety measures.
- **Staff training**: All personnel involved in the construction must be qualified after training before they can take up their posts, and special operations personnel must be certified before taking up their posts.
2. **Foundation treatment**
- **Foundation bearing capacity inspection**: After the foundation is excavated, it should be checked whether the geology meets the design requirements, the concrete foundation should be poured in time, and drainage facilities should be well prepared to avoid rainwater soaking.
- **Foundation reinforcement**: According to the geological conditions, pile foundation reinforcement or foundation treatment (such as replacement filling, grouting reinforcement, etc.) is used to enhance the bearing capacity and stability of the foundation.
3. **Safety measures during construction**
- **Construction equipment management**: The machinery, equipment, materials, etc. used should comply with national and industry standards to ensure the safety of the equipment.
- **Protection of construction personnel**: Construction personnel must wear personal protective equipment such as safety helmets and safety belts, and it is strictly forbidden to work under the influence of alcohol.
- **Lifting operation**: When lifting Bailey piers, they should be assembled in layers to avoid lifting a single set of Baileys to the top at one time, and ensure that the connection is firm before proceeding to the next step.
- **Scaffolding and protective facilities**: The erected scaffolding must be firm and reliable, and protective nets should be installed around and below to prevent people and objects from falling.
- **Electrical safety**: Temporary electricity use at the construction site should be strictly implemented in accordance with relevant specifications, use safe voltage, and ensure safe electricity use.
4. **Inspection and maintenance after construction**
- **Inspection and acceptance**: After the construction is completed, the connection of each part should be inspected and accepted to ensure the quality of construction.
- **Regular maintenance**: After the reinforcement is completed, the bridge should be inspected and maintained regularly to promptly discover and deal with potential safety hazards.
Through the above measures, construction safety can be effectively guaranteed during the reinforcement construction of Bailey bridges in mountainous areas, ensuring the stability and safety of the bridges.
