After the construction of the bridge is completed, in order to protect the safety of vehicles and pedestrians below, it is necessary to set up an additional safety protection net on the outside of the bridge's anti-collision guardrail. In order to prevent people on the bridge from throwing garbage, setting up a protection net has become a necessary measure. The protection net can not only prevent garbage from falling from a height, maintain the cleanliness and safety under the bridge, but also prevent people from falling accidentally.
[0003] After the current bridges are built, they are generally equipped with anti-collision railings, but the installation of protective nets is not common. Anti-collision railings are mainly used to prevent vehicles from running out of control and rushing out of the bridge, which is crucial for driving safety. However, in terms of preventing people from throwing garbage or other objects, the role of protective nets cannot be ignored. For this reason, we designed a protective net for road and bridge safety to solve the above problems. Utility Model Content
