Buffering anti-collision warning guardrail for road and bridge construction

Abstract

The invention relates to the technical field of guardrails, in particular to a buffering anti-collision warning guardrail for road and bridge construction, which comprises a base, a guardrail plate, a primary damping assembly, a secondary damping assembly and a silencing assembly arranged on one side of the guardrail plate, and a vertical part of the guardrail plate is fixed on the base; the damping guardrail has the beneficial effects that the primary damping assembly and the secondary damping assembly directly face a lane, the silencing assembly directly faces a road and bridge construction site, the base is fixed to the designated ground position, and when a vehicle rushes to the guardrail plate, the primary damping assembly is used for conducting primary force unloading and damping on the vehicle; secondary force unloading and shock absorption are conducted on the vehicle through the secondary shock absorption assembly, and noise generated in the road and bridge construction process is isolated through the noise reduction assembly; damping and force unloading can be effectively carried out on vehicles, major traffic accidents are prevented, noise reduction can be effectively carried out in the road and bridge construction process, and the road and bridge construction requirements are fully met.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a buffering anti-collision warning guardrail for road and bridge construction. Background technique [0002] The existing construction guardrails are generally fixed directly on the ground to isolate the lane and the road and bridge construction sites. However, some vehicles in the lane will directly hit the guardrail before they can react. Shock absorption and unloading make the vehicle and the guardrail collide hard, causing major traffic accidents; in addition, due to the huge noise generated during the construction of road and bridge, the existing guardrail only has a separation function, which can no longer meet the requirements of road and bridge construction. need. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to aim at the above-mentioned deficiencies, to provide a kind of buffer anti-collision warning guardrail for road and bridge constr...

Problems solved by technology

[0002] The existing construction guardrails are usually directly fixed on the ground to isolate the driveway and the road and bridge construction site. However, some vehicles on the driveway will directly hit the guardrail before they have time to react. The shock absorption and force unloading will make the vehicle collide with the guardrail hard, causing major traffic accidents; in addition, due to the huge noise generated during the construction of roads and bridges, the existing guardrails only have a separation function and cannot meet the requirements of road and bridge construction. need
