The safety of highway bridge construction is the premise for ensuring the smooth and timely completion of a project. In the previous article, we discussed common safety issues that occur during different stages of bridge construction. Based on this, the following points are analyzed to address accident prevention. Firstly, construction managers should carry out strict supervision in a timely manner, construction workers should enhance their safety awareness, and the construction processes should adhere to relevant standards without any negligence. This article will focus on sharing safety construction methods at different stages.

1. Foundation Pit Excavation Stage

For the safety focus mentioned in the various stages, in the excavation stage, timely measures must be taken to prevent water accumulation, ensure the stability of the retaining walls, and manage the disposal of spoil properly without random piling. Hazardous factors around the excavation, such as dangerous rocks and hillside protection, should be addressed promptly. This is to prevent accidents caused by improper operations.

2. Pile Drilling Stage

In the pile driving and excavation stage, especially during manual excavation, care must be taken to avoid the risk of collapse caused by excessively large pile holes. Measures should be taken to prevent water ingress into the pile holes during rainy weather, which could lead to pile damage. During blasting operations inside the holes, professional blasting methods should be adopted to avoid unnecessary safety hazards. In the operation of bored piles, special attention should be paid to using methods such as top-pipe and hook fixation to prevent floating cages from appearing. During construction, non-relevant personnel should stay clear of the site.

3. Pier Construction Stage

During the pier construction stage, a safety inspection must be conducted before high-altitude operations. Strict adherence to safety procedures and regulations should be ensured, and risky operations should be avoided. The scaffold connections must comply with standards. Work should not proceed in adverse weather conditions. After such weather, scaffolding and other safety equipment should be checked before continuing construction.

4. Girders, Caps, and Bridge Assembly Stage

In the construction of the upper structure of the bridge, such as the cap beam and tie beam, the installation of scaffolding and equipment must follow the standards. Care should be taken during installation to avoid negligence. The selection of lifting equipment should be based on rigorous load-bearing calculations to ensure the proper equipment is chosen. Prior to using the lifting equipment, a thorough inspection should be performed to prevent major safety incidents during lifting operations. During bridge erection, attention should be paid to synchronizing the movement of the tie beams to avoid issues such as misalignment, slipping, or crane settlement.

Conclusion

The safety of highway bridge construction is the foundation for the smooth and timely completion of a project. Effective safety construction methods are the key to successfully completing the project. By continuously improving safety construction methods and safety management experience in bridge construction, we can ensure that the construction process is conducted more safely and orderly. This not only reduces safety accidents during bridge construction but also minimizes economic losses. It is essential to emphasize that accident prevention is the key to avoiding incidents. Strengthening safety awareness through safety education helps cultivate a habit of safe construction.

Safety is the precondition for the successful progress of bridge engineering. Safety control techniques and safety management play a crucial role in the bridge construction process. To ensure smooth and safe construction, attention must be paid to the stages where accidents are likely to occur. Different safety management measures should be adopted for bridges in different environments. Different hazard warning levels should be set based on the psychological state of the construction personnel. Through a series of safety control measures, construction workers' safety awareness should gradually be strengthened, helping them develop safe construction habits. Actively building a road and bridge construction safety management system will enhance the efficiency of safety management.
