Protective fence applied to roads and bridges

Abstract

The invention discloses a protective fence applied to roads and bridges. The protective fence comprises at least one continuous protection unit arranged in parallel, each protection unit comprises a supporting rod, a connecting rod and a protection baffle, and the angle between the extension line of the advancing direction of the connecting rod and the extension line, extending towards the advancing direction of the connecting rod, of the cross section of the protection baffle is 30-45 DEG. The protection baffle is arranged obliquely to effectively improve the shielding effect of automobile lamps on light rays, a first fixing groove is formed in the top of the connecting rod, a first fixing column is arranged at the bottom of the protection baffle, and the protection baffle and the connecting rod are detachably connected, so when the local protection baffle is damaged, and the local protection baffle can be replaced and maintained, resource waste is effectively avoided; and the multiple protection units are arranged, the protective fence is arranged in a unitization mode, and if the whole protection unit is damaged, the protection unit can be replaced, so resource waste is furtheravoided.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a protective fence applied to roads and bridges. Background technique [0002] Nowadays, the development of roads and bridges is getting faster and faster, especially the development of expressways is very rapid. When many drivers drive on expressways, the lights of the cars on the opposite side often appear to be dazzling, which seriously affects the normal driving of drivers. Therefore, the guardrail of the expressway adopts the design of sheet-shaped barriers arranged at continuous intervals, which can block the lights of cars in the distance to a certain extent. However, in the actual use process, it is found that when one part of the barrier is damaged, Due to the overall design of the isolation grid and the support structure at the bottom of each piece, it is not possible to replace and repair the damaged part separately, and a large section of the isol...
