Anti-collision guardrail for municipal engineering

Abstract

The invention discloses a non-collision guardrail for municipal engineering, and relates to municipal engineering facilities, aiming at solving the problems that existing anti-collision guardrails areeasy to damage and have poor use effect. The non-collision guardrail is characterized in that the non-collision guardrail comprises a plurality of stand columns distributed along a road, a pluralityof protective base plates and buffering mechanisms are arranged between every two adjacent stand columns, the protective base plates horizontally extend along the length direction, and the two ends ofeach protective base plate are fixedly connected to the two correspondingly adjacent stand columns; each buffering mechanism comprises two stress plates which are hinged to each other horizontally, wherein the perpendicular projections of the two stress plates are in the shape of V, two arms of the V are slidably connected to the corresponding protective base plate, the stress plates are slidablyconnected along the length directions of the protective base plates, a plurality of tension springs are arranged between the two stress plates, and two ends of each tension spring are connected withthe two stress plates. The non-collision guardrail for municipal engineering has the advantages that impact forces can be buffered and absorbed, and the damage possibility is reduced while a vehicle is stopped from rushing out, so that the use effect is excellent.

Description

technical field [0001] The invention relates to municipal engineering facilities, more specifically, it relates to an anti-collision guardrail for municipal engineering. Background technique [0002] At present, the guardrails on both sides of the expressway are composed of columns and protective plates positioned on the top thereof. The protective plates are made of steel plates, and the two are rigid materials and are also rigidly connected. When the car loses control and hits the protective plate, the guardrail can prevent the car from turning into the waterproof ditch on both sides of the expressway or rushing into the opposite lane to crash. [0003] Once the existing guardrail collides with the car body, most of them cannot absorb the impact force, but can only rigidly block the car body, which makes the car body and guardrail very easy to damage, and makes the vehicle relatively easy to rush out of the guardrail. Therefore, it is necessary to propose a A new solution...
