[0002] Roads and bridges are generally composed of several major parts, including roadbeds, pavements, bridges, tunnel projects, and traffic engineering facilities. With the vigorous development of the transportation industry, the number of high-grade highways, mainly expressways and first-class highways, has increased year by year. Before the construction of road and bridge projects, a protective device is generally built to surround the road and bridge construction site. On the one hand, it ensures that the construction of road and bridge projects will not affect the surrounding environment. On the other hand, the protective device can play a safety protection role.

[0003] The protective net in the safety protection device is prone to damage after being used for a long time. Traditional protective nets are mostly fixed to the support rods with screws, so that if the protective net is damaged and needs to be replaced, the staff needs to use a series of tedious steps to disassemble it, which brings trouble to the staff in replacing the protective net. For this reason, we propose a road and bridge construction protective device. Utility Model Content
