Technical Field
The utility model relates to a road surface pavement technical field, more specifically are one kind can strengthen road surface intensity's gravel pavement structure of putting in bulk.
Background
The permeable asphalt pavement has the advantages of rapid water permeability and drainage, high running safety in rainy days, sound absorption and noise reduction and other environmental protection functions, and is currently used as a first-choice pavement structure for municipal road environmental protection and spongy construction. However, the realization of the main water permeable function depends on the large pores in the material, which causes the deficiency of the strength performance of the material, especially in the road sections such as the intersections of urban roads and bus stops, and the like, because the vehicle load generally has start-stop brake on the road sections, the kneading shear stress on the road surface is far higher than that on the common road sections, and the shear resistance of the water permeable asphalt mixture is insufficient, so that the early-stage damage such as rutting, pushing, bag closure and the like is easily formed.
At present, the following problems exist in the existing gravel pavement structure: after the gravel is paved, the structural strength between the base layer and the surface layer is weak, and the service performance of the gravel is influenced. For this reason, a new scheme needs to be designed to give improvements.

In order to achieve the above object, the utility model provides a following technical scheme: a interspersed gravel placement structure capable of enhancing pavement strength, comprising: surface course, enhancement layer, intermediate level and basic unit, the top of basic unit is arranged in to the intermediate level, the enhancement layer is arranged in between surface course and the intermediate level, the intermediate level includes a plurality of connecting block, the connecting block is hexagonal prism structure, through-hole and a plurality of connecting block formation honeycomb structure have been seted up on the surface of connecting block, it has the gravel to fill in the enhancement layer, gravel in the enhancement layer is inlayed in the through-hole, and is located gravel and basic unit surface contact below the through-hole.
As a preferred embodiment of the utility model, still be provided with a plurality of spliced pole in the intermediate level, the lower extreme and the basic unit fixed connection of spliced pole, the upper end of spliced pole upwards extend and pass the enhancement layer and with surface course fixed connection.
As an optimal implementation mode of the utility model, the connecting hole has all been seted up at the lateral wall middle part of connecting block, and is adjacent be linked together through the connecting hole between the through-hole.
As a preferred embodiment of the utility model, the surface layer adopts a high-viscosity modified asphalt mixed material, and the thickness of the surface layer is 3-5 cm.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses, through set up the intermediate level between enhancement layer and basic unit, the intermediate level is surperficial porous structure's honeycomb, when carrying out gravel packing to the enhancement layer, during partial gravel entered into the hole in intermediate level, honeycomb holes was filled up by gravel packing, played the effect of fixed gravel and increase road surface intensity.
