Description

Modularized road guardrail Technical Field The application relates to the technical field of road protection, in particular to a modularized road guardrail. Background In municipal roads, highways and cement/concrete pavement projects, road fences are important protective facilities for ensuring traffic safety and separating traffic areas. The traditional road fence adopts fixed mounting structure more, mainly comprises vertical backplate, along vertical direction interval arrangement's many stands, and stand bottom welding or bolted connection have horizontal support plate generally, reserve a plurality of installation through-holes in the backup pad. During installation, the bottom surface of the supporting plate is tightly attached to the ground of the cement or concrete base layer, and the expansion screw penetrates through the through hole and is anchored into a preset hole site, so that the rigid connection between the fence and the ground is realized. The structure is widely applied to the existing road engineering due to simple installation and better stability, and becomes a conventional configuration form of a road protection system. In the long-term operation process of municipal roads and highways, diseases such as cracks, subsidence, rutting and the like are easy to occur on the road surface, and in order to restore the service performance of the road surface and improve the travelling comfort, a new asphalt layer is additionally paved on the original road surface structure, which is a high-efficiency maintenance mode commonly adopted in the industry. The process can rapidly improve the flatness and the structural strength of the pavement on the premise of not breaking the original pavement in a large amount, and is widely applied to periodical major-minor repair engineering. After the paving construction is completed, the whole elevation of the road surface can be correspondingly lifted, the original installation height of the road fence which is installed in place still is maintained, the effective protection height of the road fence relative to the road surface is passively reduced along with the lifting of the road surface, and the current standard and the safety protection requirement are difficult to continuously meet. Aiming at the problem of insufficient effective protection height of the rail after paving the pavement, the traditional processing mode is to wholly dismantle the original road rail, and to newly purchase and install a complete guardrail system matched with the elevation of the new pavement. On one hand, a large number of components such as guardrail posts and guard plates still having the use function are forcibly abandoned, high cost is generated when new components are purchased and old components are disposed, the resource waste is serious, on the other hand, the whole dismantling and reinstallation procedures are complicated, the construction period is long, the existing lanes are required to be occupied for a long time, the interference on normal traffic flows is extremely large, road section congestion is easy to cause, the construction efficiency and economy are poor, the actual requirements of modern road rapid maintenance are difficult to adapt, and an improvement space exists. Disclosure of Invention The application aims to provide a modularized road guardrail, which solves the problems of insufficient protection height of a fence after pavement paving, high cost, low efficiency, large traffic interference and resource waste of the traditional integral replacement mode in the related art. The modularized road guardrail provided by the application adopts the following technical scheme: The modularized road guardrail comprises a guard plate which is vertically arranged, and two stand columns which are fixedly arranged on one side of the guard plate along the vertical direction, wherein adjusting rods which can be adjusted up and down are coaxially and slidably arranged on the top surfaces of the stand columns, extension plates which are positioned above the guard plate are fixedly arranged on the periphery of the adjusting rods together, the extension plates can move downwards along with the adjusting rods to a transportation state which is in butt joint with the guard plate, can move upwards along with the adjusting rods to an application state which is in a distance with the guard plate, and limiting pieces which are used for fixing the transportation and application states of the adjusting rods are arranged outside the stand columns. Through adopting above-mentioned technical scheme, the guardrail need not whole demolishs when the road surface adds to spread the maintenance and changes, only drives the extension board through the regulation pole and reciprocates, can the whole effective guard height of quick adjustment guardrail, makes it and new road surface elevation looks adaptation, satisfies current safety protection standard requirement.
