Technical Field

[0001] This invention relates to the field of protective equipment, and more specifically, to a protective device for municipal bridge engineering. Background Technology

[0002] In my country, municipal infrastructure refers to various buildings, structures, and equipment installed within the planned construction area of ​​urban areas and towns (townships) to provide paid or free public goods and services to residents based on government responsibility and obligations. The construction of various public infrastructure supporting urban life falls under the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, waterways, rail transit, sewage treatment, and waste disposal projects.

[0003] Construction on bridges typically involves work beneath the bridge deck or on the outer surface of the piers. Due to the height of bridges, cranes are generally used to raise workers to the work position, or specialized vehicles are used to lower workers from the bridge into a suspended platform. However, the platform or crane can only take workers to one location at a time, and the limited space makes it difficult to carry out the work. This is a limitation of existing technology.
