Detailed Description

The following will describe a polyurethane color gravel pavement structure in further detail with reference to specific embodiments and drawings.

As shown in fig. 1, fig. 2 and fig. 3, in a preferred embodiment, the polyurethane color gravel pavement structure of the present invention includes a roadbed 1, a drainage layer 2 is disposed on the roadbed 1, a water permeable supporting layer 3 is disposed on the drainage layer 2, and a gravel surface layer 4 is disposed on the water permeable supporting layer 3; the macadam surface layer 4 is made of polyurethane color macadam composite materials. When the road surface is laid, firstly, the road surface 1 is tamped and leveled, then the drainage layer 2 is laid, and the drainage layer 2 can guide the water permeating into the road surface out of the road surface, so that the drainage efficiency of the road surface is improved, and the softening and the like of the road surface 1 caused by the water permeation are avoided; after the drainage layer 2 is laid, a permeable supporting layer 3 is laid, the permeable supporting layer 3 plays a main supporting role, the thickness is thick, and the specific thickness is determined according to engineering requirements; finally, paving a broken stone surface layer 4, wherein the broken stone surface layer 4 is made of polyurethane color broken stone composite materials, the color broken stones are bonded by utilizing polyurethane to form floor brick-type blocks and then are paved, compared with the traditional mode of paving the simple exposed broken stones, the broken stones adopted in the embodiment are not easy to slide after the polyurethane is adopted, the antiskid effect is good, the walking is more comfortable, the polyurethane is wear-resistant and corrosion-resistant, the durability of the pavement is prolonged, in addition, the pavement broken stones form an integral bearing, the effect of certain buffering and dispersing force is realized, and the ground is not easy to dent; by adopting the colored macadam, the ground has more ornamental value, and the use experience is improved.

In order to further improve the drainage effect of the ground structure, the drainage layer 2 comprises a plurality of strip-shaped drainage blocks 21 which are transversely paved, drainage grooves 22 are formed in the drainage blocks 21, and at least one end of each drainage groove 22 is open; during the moisture that permeates into ground gets into water drainage tank 22, the ground structure of discharging through water drainage tank 22 that can be quick, when laying ground, water drainage tank 22 open one side towards the roadside escape canal, rivers discharge into the escape canal fast like this, guarantee that the road surface can not ponding, improve drainage efficiency. In this embodiment, the drainage block 21 is made of a waterproof material, such as an asphalt waterproof material, a concrete material added with a waterproof agent, and the like, and moisture is difficult to permeate the drainage block 21 and enter the roadbed 1, so that the roadbed 1 is ensured to be dry and not softened and collapsed due to long-term water soaking. When there is the escape canal in road surface engineering both sides, the drainage groove 22 also can set up both ends opening, also can reach the same technological effect.

Preferably, the water permeable support layer 3 includes a concrete support block 31 and a water permeable filling material 32, the concrete support block 31 includes a base 311 and a plurality of support columns 312 disposed on the base 311, and each support column 312 is provided with a water permeable hole 313 penetrating up and down. Concrete supporting shoe 31 plays main bearing and supporting role, guarantees that road surface structure compressive strength is high, is difficult for collapsing, and sets to support column 312 and the filler material 32 cooperation that permeates water, has reached high compressive resistance promptly, has fine water permeability again, and the rainwater can be directly through the filler material 32 seepage that permeates water, and when the rainfall is big, can further improve the drainage effect that permeates water through the hole 313 of permeating water, ensures that the road surface can not ponding. In this embodiment, the permeable filling material 32 can be directly made of common crushed stone, and after being laid, the height of the permeable filling material is as high as that of the top end of the supporting column 312, and after being leveled and tamped, a surface layer is laid.

In order to further improve the drainage effect, reduce the pavement paving difficulty and improve the structural stability of the pavement, the width of the concrete supporting block 31 is consistent with the width of the drainage block 21, and the water permeable holes 313 on the concrete supporting block 31 correspond to the drainage grooves 22 on the drainage block 21 during paving, so that when the water flow is large, the water flow directly enters the drainage grooves 22 through the water permeable holes 313 to be discharged out of the ground, and the drainage efficiency is high.

In order to improve the structural stability and save raw materials, the number of the supporting columns 312 on the supporting blocks 31 is three, and the supporting columns 312 are arranged on the base 311 in a delta shape, so that when a road surface is paved, after the supporting blocks 21 are paved, the density of the supporting columns 312 is large, the interval is small, and compared with the structure (two or four supporting columns) which is designed in parallel and in one line or two lines of supporting columns 312 in a subsection mode, the comprehensive cost performance is optimal.

In order to enhance the stability of the whole pavement structure, a reinforcing plate 5 is arranged around the pavement structure and used for surrounding the pavement structure and preventing the materials in the pavement structure from collapsing and the like due to peripheral diffusion. The reinforcing plate 5 can be made of steel structures or high-performance concrete materials. In order to ensure the drainage effect, a drainage hole needs to be formed in the reinforcing plate 5, and the position of the drainage hole corresponds to the bottom gap of the drainage groove 22 and the supporting column 312.
