Description

Technical Field

[0001] The present invention relates to the technical field of municipal construction facilities, and in particular to a guardrail used on a municipal road bridge. Background Art

[0002] Bridges generally refer to structures erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected across mountain streams, poor geology, or to meet other transportation needs to make communication more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the support locations of the span structure and the piers or abutments; and the ancillary structures refer to the bridgehead slabs, conical slope protection, revetments, diversion projects, etc.

[0003] The guardrail of a bridge is a safety protection facility, which not only has the function of protecting the safety of people, but also can increase the beautification effect of the bridge. In the Chinese utility model patent document with the publication number CN206448160U, a municipal bridge guardrail is disclosed, which achieves the effect of anti-slipping of the fixing bolts by installing upper gaskets and lower gaskets, and achieves the effect of anti-slipping of the upper gasket and the lower gasket by setting the anti-slip groove and the anti-sliding block to engage, thereby achieving the effect of preventing the installation base from loosening, and by setting the inside of the connecting hole to be respectively plugged with the first secondary guardrail and the second secondary guardrail, the first main guardrail and the second main guardrail can be made more stable, and by setting the reinforcing ribs, the bottom of the first main guardrail and the second main guardrail can be effectively prevented from breaking, and the stability can be increased, and by setting the inside of the street lamp groove and the street lamp hole to fix the installation rod, the nighttime lighting of the bridge can be effectively enhanced, and the stability of the guardrail can be reduced by preventing accidental collision, and by setting the protective shell and transparent tempered glass, the possibility of the light rod being damaged can be effectively reduced, thereby effectively solving the problem that the bridge guardrail is easy to loosen after long-term use.

[0004] However, since the bridge guardrails are set up in the open air, dust accumulates on the bridge for a long time, resulting in the need for frequent cleaning of the bridge guardrails. When cleaning the guardrails, sanitation workers are required to drive sprinkler trucks or use buckets to fill water to the bridge guardrails, and then clean the guardrails, which is inconvenient to get water. Moreover, most of the existing guardrails are connected by welding, which is prone to rigid deformation when hit, thereby reducing the protective effect. Summary of the invention
