Technical Field
The utility model relates to a road anticollision barrier field, concretely relates to utilize road surface of existing wave form guardrail to add shop's 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 uncontrolled driving, and can effectively reduce traffic accidents and property loss, thereby being widely applied.
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 great part of the projects are additionally paved on the original road, so that the road surface elevation is higher and higher, and the road surface is raised after the major parts of the waveform guardrail foundations, the upright posts and the waveform breast boards are completely paved, so that the height of the existing waveform guardrail is insufficient, the safety standard is not met, and the existing waveform guardrail cannot be used continuously. In the prior art, when a road is paved, a common method is to dismantle and rebuild the waveform guardrail which comprises a foundation, an upright post and a waveform sideboard, so that a great deal of social resources are wasted, and the maintenance fund which is originally caught and sees elbows is frosted on snow.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an utilize existing waveform guardrail's road surface to add and spread the structure to need rebuild waveform guardrail again after rebuilding among the solution prior art, big well road surface of repairing and spreading, lead to the problem of the resource and the cost a large amount of wastes, realize the existing resource of make full use of, subtract short project duration, reduce engineering cost's purpose.
The utility model discloses a following technical scheme realizes:
the pavement additional paving structure utilizing the existing waveform guardrail comprises an existing upright post, a new pavement paved above the existing pavement and an additional upright post, wherein the bottom end of the existing upright post is embedded in the existing pavement, the additional upright post is embedded in the new pavement, the top end of the additional upright post is higher than the top end of the existing upright post, and the additional upright post is connected with the existing upright post; the guardrail plate is arranged on the newly-added upright post.
After the road surface is reconstructed and paved on a large and medium-sized road surface in the prior art, the road surface is lifted, the height of the existing waveform guardrail is insufficient, the safety standard is not met, and the road surface cannot be used continuously; and rebuild the wave form guardrail and lead to resource and cost a large amount of extravagant again, for this reason, the utility model provides an utilize the road surface of existing wave form guardrail to add the shop structure, among the existing wave form guardrail, two parts including the breast board of existing stand and guardrail, this structure keeps existing stand to continue to bury underground and keeps unchangeable in existing road surface, pulls down the guardrail breast board, directly pours new shop face on existing road surface. In order to guarantee the road surface and increase the mounting height of back guardrail, the utility model discloses set up newly-increased stand next door, newly-increased stand links to each other with existing stand, and makes the top of newly-increased stand be higher than the top of existing stand. The concrete height of the newly-added stand columns is adapted according to the designed height of the heightened pavement, and the requirements for the height of the guardrail in relevant safety specifications are met. The utility model discloses the new pavement surface of pouring does not have the bottom of newly-increased stand to can bury the bottom of newly-increased stand underground in the new pavement, ensure the stability of newly-increased stand.

For a straight road, the newly added upright posts and the existing upright posts are distributed along the axis direction of the road; but to the crooked section of road, then arrange according to the central line direction to make newly-increased stand, existing stand keep equal to the distance at road center, make the distance of guardrail to road center through this application setting, keep unchangeable with the distance of original guardrail to road center.
Furthermore, the existing upright post is of a hollow structure, and expansion concrete is poured inside the existing upright post. Improve the structural strength and the hardness of existing stand, make its atress basic unit spare as newly-increased stand, when the vehicle was out of control to collide the guardrail, the vehicle keeps forward power under inertial action, leads to the stand to take place the deformation of horizontal direction easily, in case out of control deformation then easily dashes out the road, and through the reinforcement to the existing stand of newly-increased stand in the same horizontal plane in this scheme, the anti horizontal deformation ability of newly-increased stand has effectively been improved, thereby improved the utility model discloses an overall safety nature.
The pavement paving method by using the existing waveform guardrail comprises the following steps:
(a) disassembling the existing corrugated guardrail, taking down the guardrail plate and keeping the existing upright post;
(b) installing a newly-added upright column beside the existing upright column, so that the top end of the newly-added upright column is higher than that of the existing upright column; fixing the newly added upright post;
(c) pouring a new pavement on the existing pavement, so that the bottom end of the newly added stand column is positioned in the poured new pavement;
(d) and installing the taken-down breast board on the newly-added upright post.
The method makes full use of the upright post and the breast board structure of the existing waveform guardrail, does not need to dismantle the existing upright post and re-form holes, has quick and convenient construction, and has lower construction cost than the original traditional method of dismantling and then building the guardrail. In addition, the method does not need to rebuild the guardrail column foundation, so that the maintenance cost can be obviously reduced, and the construction efficiency can be improved. Therefore, the method can fully utilize the existing resources, reduce the maintenance cost, realize quick construction, greatly shorten the construction period, reduce the construction cost and be widely used in road engineering reconstruction and major and middle maintenance.
And (c) further, in the step (b), the newly-added stand columns are fixedly connected with the existing stand columns through a plurality of connecting pieces, and the height of each connecting piece is higher than the height of the newly-paved road.
Further, step (d) further comprises: and pouring the expansive concrete into the existing upright columns.
Compared with the prior art, the utility model, following advantage and beneficial effect have:
the utility model discloses utilize the road surface of existing waveform guardrail to add and spread the structure, make full use of the stand and the breast board structure of existing waveform guardrail, need not demolish existing stand, also need not pore-creating again, the construction is convenient fast, makes the price ratio original tradition demolish newly-built guardrail cheap moreover. And, because the utility model discloses need not to rebuild the guardrail stand basis again, consequently can also show reduction maintenance cost, improve the efficiency of construction.
