Embodiment Construction
[0040] like figure 1 and 2 As shown, the hard road with modified permeable structure in this embodiment includes: garage roof rigid protective layer 1, water filter layer 2, geotextile 3, water permeable soil layer 4, gravel cushion 5, dead pipe 6, Concrete cushion 7, dry hard cement mortar 8, granite pavement 9, drainage ditch 10, drainage ditch cover 11, geotextile 12 and cobblestone 13.
[0041]When the water flow accumulates on the road, it gradually flows to the drainage ditch 10 through the slight slope of the granite road surface 9, and the drainage ditch cover 11 is covered with geotextiles 12 and cobblestones 13, and the large particles of impurities in the accumulated water are filtered and removed by the cobblestones 13 and geotextiles 12 Then enter the drainage ditch 10, and gradually infiltrate the gravel cushion layer 5 through several blind pipes 6 at the bottom of the drainage ditch 10, thereby infiltrating downward into the water-permeable soil layer 4. The a...

The invention discloses a hard road with a modified water-pervious structure, relating to the technical field of permeable road construction. The hard road comprises a hard pavement paving structure,a water collection module, a permeable layer and a water-pervious structure, wherein the top surface of the hard pavement paving structure is obliquely distributed; the water collection module is arranged on a relatively low side of the hard pavement paving structure and is used for collecting and eliminating rainwater; the permeable layer is paved below the hard pavement paving structure; and thewater-pervious structure is used for introducing water in the water collection module into the permeable layer. According to the hard road, large particulate pollutants can be effectively entrapped sequentially through collection and permeation, so that compared with a traditional water-pervious paving structure, the hard road has relatively excellent water-pervious capacity; a bottom water storage layer has a certain adsorption effect, so that most surface gathered water can be cleared, and the urban inland inundation disaster is effectively prevented; and the maintenance cost is relativelylow, the cleaning is convenient, and the drawbacks that the traditional water-pervious paving structure is easily blocked and troublesome to clean are well overcome.
Description
technical field [0001] The invention relates to the technical field of permeable road construction, in particular to a hard road with a modified permeable structure. Background technique [0002] With the development of the city, hard pavement is used as the most important brick pavement in the area other than buildings and surrounding greening. The use of large areas has led to increased surface runoff, serious water accumulation on the road, and frequent occurrence of urban waterlogging and non-point source pollution. phenomenon has received great attention. Since the concept of "sponge city" was put forward, the permeable pavement system, as an important source control technology of this concept, has been widely used in engineering practice. [0003] The current permeable pavement is a pavement system with fully permeable or semi-permeable pavement. It is generally believed that its structure is divided into four parts: the surface layer, the base layer, the sub-base la...
