Description

Technical Field

[0001] The utility model relates to the technical field of road paving structures, in particular to a greenway paving structure close to a water body. Background Art

[0002] Greenways are linear green open spaces, usually tree-lined paths, recreational routes for pedestrians and cyclists (excluding electric vehicles), usually built along natural roads and artificial corridors such as riversides, valleys, ridges, and scenic belts. With the increasing awareness of ecological protection, there are more and more wetland parks in China, and most of them are paved with greenways for people to use. However, the greenways in wetland parks are close to water bodies, and the existing greenways have poor drainage capacity. Therefore, due to the influence of water bodies, the greenways in wetland parks are prone to sedimentation, resulting in poor stability of the greenways, affecting normal use, thereby reducing the service life of the greenways. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a greenway paving structure close to a water body. In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0004] A greenway paving structure close to a water body comprises a plain soil layer, a crushed stone layer, a plain concrete layer, an emulsified asphalt permeable layer, a coarse aggregate asphalt layer and a fine aggregate asphalt layer which are laid in sequence from bottom to top, wherein the plain soil layer, the crushed stone layer and the plain concrete layer are all convex, and precast concrete curbs are arranged on both sides of the plain concrete layer, and the precast concrete curbs are enclosed on both sides of the emulsified asphalt permeable layer, the coarse aggregate asphalt layer and the fine aggregate asphalt layer.

[0005] Furthermore, fine stone concrete beds are arranged on both sides of the raised part of the plain concrete layer, and the precast concrete curb is arranged in the fine stone concrete beds.

[0006] Furthermore, the top layer of the coarse aggregate asphalt layer is provided with a tack coat oil.

[0007] Furthermore, a white hot-melt anti-skid road marking is arranged on the top of the fine aggregate asphalt layer.

[0008] Furthermore, the surface of the fine aggregate asphalt layer is arranged with a certain slope, and the lower side of the fine aggregate asphalt layer is close to the water body.

[0009] Furthermore, the slope of the fine aggregate asphalt layer is 1%.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The contact area between the gravel layer and the soil layer is increased by using the convex structure of the plain soil layer and the gravel layer, thereby increasing the drainage of the greenway structure. The convex structure of the plain concrete layer is coordinated with the curbs on both sides to increase the overall structural connectivity between the curbs and the plain concrete layer, thereby increasing the stability of the greenway structure. Both the fine aggregate asphalt layer and the coarse aggregate asphalt layer have a certain water absorption capacity, which can reduce water accumulation on the road surface and reduce the impact of water accumulation on pedestrians.

[0015] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1 As shown, the utility model provides a technical solution, a greenway paving structure close to a water body, comprising a plain soil layer, a crushed stone layer, a plain concrete layer, an emulsified asphalt permeable layer, a coarse aggregate asphalt layer and a fine aggregate asphalt layer laid in sequence from bottom to top, the plain soil layer, the crushed stone layer and the plain concrete layer are all convex, precast concrete curbs are arranged on both sides of the plain concrete layer, and the precast concrete curbs are enclosed on both sides of the emulsified asphalt permeable layer, the coarse aggregate asphalt layer and the fine aggregate asphalt layer.

[0017] Specific laying method: first dig a soil trench, and compact the soil at the bottom of the trench to form a "convex" soil layer, then lay a 200mm thick gravel layer on the compacted soil layer. The bottom and both sides of the gravel layer are in contact with the soil, which increases the drainage of the greenway. A 150mm thick plain concrete layer is laid on the top of the gravel layer as an intermediate layer to increase the stability of the greenway. Fine stone concrete beds are set at both ends of the plain concrete layer and buried in the soil. The groove formed between the fine stone concrete beds and the plain concrete layer is set There are prefabricated concrete curbs, and an emulsified asphalt penetration layer is arranged on the plain concrete layer. The emulsified asphalt penetration layer is easy to construct and has good penetration effect, which increases the drainage of the greenway. A 60mm thick coarse aggregate asphalt layer is laid on the emulsified asphalt penetration layer, and a tack coat oil is arranged on the coarse aggregate asphalt layer. A 40mm thick fine aggregate asphalt layer is laid on the tack coat oil. The tack coat oil mainly plays a bonding role, and the coarse aggregate asphalt layer and the fine aggregate asphalt layer are bonded into a whole through the tack coat oil. A white hot-melt anti-skid road marking is drawn at the top center of the fine aggregate asphalt layer.

[0018] The contact area between the gravel layer and the soil layer is increased by using the convex structure of the plain soil layer and the gravel layer, thereby increasing the drainage of the greenway structure. The convex structure of the plain concrete layer is coordinated with the curbs on both sides to increase the overall structural connectivity between the curbs and the plain concrete layer, thereby increasing the stability of the greenway structure. Both the fine aggregate asphalt layer and the coarse aggregate asphalt layer have a certain water absorption capacity, which can reduce water accumulation on the road surface and reduce the impact of water accumulation on pedestrians.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
