Protective fence plate mechanism used for road and bridge engineering

Abstract

The invention provides a protective fence plate mechanism used for road and bridge engineering. The protective fence plate mechanism used for road and bridge engineering comprises bases, protective net storage chambers and buffering slide blocks; one group of protective fences is connected to the rear end surface of each base through four groups of bottom connecting rods; the two adjacent groups of protective fences are connected with each other through multiple groups of side connecting rods; two groups of oil pressure buffers are arranged on the internal sides of the lower parts of the basesand the protective fences; and in a normal state, the bases are fixedly connected with the protective fences through bolts. As protective nets are arranged, vehicles are protected, the vehicles are prevented from falling off from a gap after rushing out a pavement; according to the protective fence plate mechanism used for road and bridge engineering, through adoption of a multi-stage protectionand blocking mode, the vehicles are prevented from rushing out the pavement to fall off to cause tragedies, the safety is greatly enhanced, the floor space is smaller, the manufacturing cost is low, and the protective fence plate mechanism used for road and bridge engineering is suitable for substantial promotion.

Description

technical field [0001] The invention belongs to the technical field of road engineering and traffic facilities, and more specifically relates to a guardrail mechanism for road and bridge engineering. Background technique [0002] With the development of the economy, vehicles are used more and more frequently, road construction is more and more, and traffic accidents occur more and more frequently. For bridge decks or winding roads, the protective fences of roads and bridges are particularly important. Existing guardrails generally adopt steel plates or pipes to be fixed on the roadbed for protection. [0003] For example application number: CN201210323373.3 A kind of road guardrail, comprises guardrail post (1) and guardrail body (2), and described guardrail body (2) is installed on the guardrail post (1), is characterized in that: described guardrail body ( 2) It includes a guard plate (3) made of elastic plastic, a corrugated steel plate (4), and N elastic component units...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a protective fence mechanism for road and bridge engineering to solve the problem of adopting a protective fence fixed on the roadbed and setting a buffer device. However, when a large traffic accident actually occurs, it is generally due to the The momentary excessive impact force causes the bolts or weak structures to break, causing tragedy. Adding a buffer device to the guardrail has little effect on improving the overall strength. The protective measures are only the first-level protection of the guardrail itself. Structural breakage will inevitably lead to tragic car crashes, and safety needs to be improved
