Problems solved by technology

[0005] In order to solve the problems that some urban roads are prone to frost heaving, the noise generated by the friction of road car tires on the road surface is relatively large, and the rainwater purification and storage is not done well enough. The road surface effectively overcomes the problems that the existing urban drainage pipe network system cannot solve the water system pollution caused by rainwater runoff, the waterlogging caused by storm runoff, the more serious air quality problems, and the safety hazards caused by the easy frost heaving of urban roads in winter.

Embodiment 1

[0041] like Figure 1-3 Shown, the pavement structure of the present invention comprises road (1), curb stone (4), water-permeable antiskid surface layer (2), temporary storage tank (19) and municipal pipeline network (22) successively from the middle to both sides; 1) Respectively arrange curbstones (4) in the shape of rectangular troughs on the left and right sides. The material of the curbstones (4) is preferably made of granite or relatively hard concrete. The length is set between 360-400cm, and the width is set at Between 60-80cm; the height of the part of the curb (4) beyond the road (1) is set between 25-35cm; the upper part of the rectangular cavity is provided with a curb rainwater inlet (6) on the side close to the road (1) , the interior of the rectangular cavity is sequentially arranged with a rainwater storage layer (5), a permeable foam concrete (12), a graded crushed stone layer (13), a water purification layer (14), a non-woven A geotextile layer (15) and an ...

Embodiment 2

[0043] like figure 2 As shown, when the road surface has a slope, the entire road structure is preferentially perpendicular to the direction of the slope.

Embodiment 3

[0045] like image 3 As shown, this embodiment is the same as figure 1 The embodiments in the above are basically the same in structure and principle, the difference is that the road surface structure proposed in this embodiment is generally applicable to some hard roads with less required load in the park, such road cars, bicycles, motorcycles, There are few pedestrians, so the load required on the road surface is small, and the air quality in the park is relatively good, so the road surface can be paved with permeable bricks with good quality and high hardness. Some roads with less traffic and less load.

Abstract

The invention relates to a rainwater collecting ecological porous road surface having functions of purifying air and preventing frost heave, and belongs to the fields of technical control on air purifying, noise reducing, sewage interception, water collecting, water draining, and rainwater filtering and purifying treatment. The road surface structure sequentially comprises a highway, border stones, porous skidproof surface layers, temporary water storage ponds, municipal pipe network and the like from middle to two sides. Porous foam concrete, graded broken stone layers, water purification layers and a non-woven geotextile layer are arranged for performing effective filtration on seeped water; and when the road surface has a slope, the whole road structure is preferentially perpendicular to the direction of the slope. The rainwater collecting ecological porous road surface disclosed by the invention is simple in structure, good in stress performance, good in seepage effect, low in paving cost and simple in paving technology; the road structure can recover, store, filter and purify rainwater, and the problem of water gathering on the road surface is effectively solved; and besides, air is purified, the problems that in winter, the road surface in a northern city is poor in frost heave resistance property can be effectively solved, the heat island effect is reduced, the city noise pollution is effectively improved, and the rainwater collecting ecological porous road surface is ecological and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical control field of air purification, noise reduction and pollution interception, water collection and drainage, and rainwater filtration and purification treatment, and in particular relates to a rainwater collection ecological permeable pavement with the functions of air purification and frost heaving prevention. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, filters, and purifies water, and "releases" the stored water and uses it when necessary. [0003] As an important method of "ecological drainage", permeable pavement has become an important p...
