Description

Heat insulating function pervious concrete pavement structure

Technical field

The utility model belongs to the road structure technical field, specifically, relates to a kind of heat insulating function pervious concrete pavement structure.

Background technology

Along with the development of national economy, to road construction require increasingly highly, low-carbon (LC), environmental protection, ecological requirement have been proposed in the construction at home.At present, road pavement uses porous pavement in a large number, mainly contains pervious concrete pavement and permeable brick paving.The effect of porous pavement is to eliminate surface gathered water, the protection groundwater resources, and the realization soil is freely breathed.In the solar radiant energy of earth surface, infrared rays accounts for 50%, and solar radiation is the main cause that causes face of land high temperature in summer.Porous pavement of the prior art can not effectively be alleviated ground high temperature.

The utility model content

The technical problem that the utility model will solve is, the deficiency to existing porous pavement exists provides a kind of heat insulating function permeable pavement structure, and it can realize road pervious function and can be heat insulation.

For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of heat insulating function pervious concrete pavement structure; Comprise the pervious concrete layer, wherein said road structure also comprises the antimony-doped stannic oxide layer, and said antimony-doped stannic oxide layer is layed on the pervious concrete layer.

As a kind of preferred version of the utility model, the thickness of said antimony-doped stannic oxide layer is 10～100 μ m.

Implement the heat insulating function pervious concrete pavement structure of the utility model; Has following beneficial effect: the pervious function and the heat insulation and heat control function that can realize road simultaneously; This functional form material-paving of antimony-doped stannic oxide layer is on urban road, square, park road; To meet the requirement of low-carbon (LC), environmental protection, ecology improving aspect performance enormous function such as urban environment, reduction urban heat land effect.

Description of drawings

To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:

Fig. 1 is the new structural representation of this practicality.

The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer, below in conjunction with embodiment and accompanying drawing, to the utility model further explain.

Heat insulation coating material is a kind of constructional materials of environmental protection; Its infrared rays in can reflected solar radiation can be alleviated the road surface and under the irradiation of sunray, heat up, and reduces pavement temperature; Reduce urban heat land effect; In pervious concrete surface-coated one deck heat insulating function coating, the two is combined, process brand-new heat insulating function pervious concrete.

As can be seen from Figure 1, the pervious concrete pavement structure of the utility model comprises pervious concrete layer 1, is equipped with one deck on the pervious concrete layer 1 and is used for heat insulation antimony-doped stannic oxide layer 2.Be specially: after pervious concrete layer 1 had been laid, one deck antimony-doped stannic oxide layer 2 was laid in maintenance 7 days on pervious concrete layer 1.Antimony-doped stannic oxide (ATO), it is the n type, semiconductor material, its visible light transmissivity has high reflectance up to more than 75% for infrared rays.It was with insulating moulding coating commonly used was different in the past, and heat-insulating efficiency is high, but also can process the different color of the various depths.

When the thickness of antimony-doped stannic oxide layer 2 is 10～100 μ m, both can obtain effect preferably, economize on resources again.

Pervious concrete layer 1 is a loose structure; Its heat storage capacity is lower than common real core road surface; Increase antimony-doped stannic oxide layer 2 on pervious concrete layer 1 surface, because the effective reflected infrared ray of antimony-doped stannic oxide layer 2 ability makes that this pervious concrete structural heat-insulation temperature reduction performance is good.Pervious concrete layer 1 is the vesicular structure surface, can increase the application life of antimony-doped stannic oxide layer 2, and the surface is not easy to wear, thereby can guarantee the persistence of heat insulating function.At widely used constructional materialss such as road, parks, square, it is wide to lay area as a kind of for pervious concrete, is widely used behind this pervious concrete with heat insulating function, and for effective urban environment that improves, reducing urban heat land effect has significant effect.

Certainly; This coating material can be organic composite material or the inorganic composite materials that can realize heat insulating function; This coating material and pervious concrete can strong bonded, must have good weatherability, alkali resistance and ageing resistace, and the coat outward appearance can be processed clear, colorless or colored.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
