Construction safety covers all safety issues during the operation process and involves relevant contents such as management, finance, and logistics support. The Chinese government has always attached great importance to production safety, people's lives and property safety, and has formulated relevant laws and regulations. With the development of the social economy, more and more road bridges need to be built or rebuilt. However, during the bridge expansion process, devices are needed to warn pedestrians and vehicles to prohibit passing, so as to avoid accidents involving pedestrians, vehicles, and construction workers.

[0003] A safety protection device for bridge reconstruction and expansion is installed with a lifting mechanism. When in use, the threaded rod is rotated, and the threaded rod drives the first support column to move up and down, which plays a role in raising the height of the warning light and attracting the attention of pedestrians and vehicles in the distance. And when the warning light at a high place fails, the height of the warning light is lowered, which plays a role in facilitating the quick replacement of the warning light. It is installed with a warning mechanism. When in use, through the warning light inside the fixing frame, it plays a role in reminding pedestrians and vehicles at night that the road here is blocked. However, in the existing technology, this device generally uses guardrails for isolation, and this method cannot play a role in reminding of the construction ahead at night, and traffic accidents are likely to occur.
