Technical Field
The utility model relates to a road construction field, concretely relates to guardrail stand risees structure.
Background
The waveform guardrail is used as an important safety accessory facility of a road, can effectively prevent vehicles from rushing out of the road due to faults or driving out of control, and is widely applied to reducing traffic accidents and property loss.
At present, in practical engineering, the waveform guardrail is widely utilized. Along with the construction of a large amount of highway infrastructure in China, more and more highway major repair and intermediate repair projects are continuously developed, wherein a large part of the projects are paved on the original road, so that the road surface elevation is higher and higher, and most of the waveform guardrail foundations, the upright posts and the waveform guardrail plates are intact. The common method is to dismantle and rebuild the waveform guard bar, including the foundation, the upright post and the waveform guard board, which causes a great deal of social resource waste, and the maintenance fund is originally caught in the elbow, so that frost is added on snow. How to effectively and fully utilize the existing resources and reduce the maintenance cost is a subject of constant exploration of relevant units and departments.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a guardrail stand risees structure to solve among the prior art reconstruction, the big well road surface of building and spread the back road surface and improve and the existing guardrail height needs newly-built problem inadequately, realize the original guardrail of make full use of, shorten construction period, practice thrift construction cost's purpose.
The utility model discloses a following technical scheme realizes:
the utility model provides a guardrail stand risees structure, is including fixing the existing stand on former road surface to and be located adding of former road surface top and spread the rear pavement, the sleeve is established to existing stand overcoat, telescopic bottom is located adds and spreads rear pavement surface, pass through bolted connection between sleeve and the existing stand, telescopic top is higher than the top of existing stand, can dismantle on the sleeve and connect guardrail breast board.
Aiming at the problem that after the reconstruction and the additional pavement of the large and medium-sized road surface in the prior art, the guardrail needs to be dismantled and rebuilt again, and comprises a foundation, stand columns and wave-shaped fence plates, which cause the waste of a large amount of social resources, the utility model provides a guardrail stand column lifting structure, the existing stand columns are fixed on the original road surface, after the additional pavement of the original road surface is lifted, the pavement after additional pavement is arranged above the stand columns, at the moment, the existing stand columns are buried in the original road surface and the pavement after additional pavement and extend out to the upper part of the pavement after additional pavement, at the moment, the extending height of the existing stand columns can not meet the required height of the guardrail, the sleeve is sleeved outside the existing stand columns, the bottom of the sleeve is positioned on the surface of the pavement after additional pavement, the sleeve is connected with the existing stand columns through bolts to ensure the stability, and the top end of the sleeve is higher than the top end of the existing stand columns, so that the extension of the existing stand columns is realized through the sleeve, and the, guardrail breast board detachable connects on the sleeve, can realize not dismantling existing guardrail, not rebuild basis, stand and change the basis of guardrail breast board again, realizes setting up the purpose of guardrail to the road surface after additionally laying. The existing structure of this structure make full use of current guardrail need not pore-creating again, and the construction is convenient fast, and the cost is too late moreover former tradition demolish the 1/4 of newly-built guardrail again, simultaneously can be once more after follow-up improvement road surface elevation once more the sleeve, improve the sleeve height can, consequently the utility model discloses really realized along with infrastructure's continuous development and sustainable synchronous effect of following up.
