Description

Technical Field

[0001] The utility model belongs to the technical field of flooring, and relates to an environmentally friendly flooring. Specifically, the utility model relates to a water-permeable and purified flooring. Background Art

[0002] With the development of economy and the acceleration of urban construction, many towns have gradually replaced the original green space with reinforced concrete houses, large infrastructure and various impermeable sites. Most of the sidewalks, bicycle lanes, suburban roads, open-air parking lots, ground surfaces of courtyards and streets, and public squares in most cities in my country prefer to choose hardened pavements made mainly of neat and beautiful stone slabs or cement and other traditional materials. This plays an important role in preventing bank erosion, but it also isolates the organic connection between the water ecological environment and the terrestrial ecological environment, which makes most of the surface of modern cities covered by hardened ground. These impermeable materials destroy the natural permeability of the ground, thus causing a series of ecological problems and forming an ecological "artificial desert". The groundwater level has dropped sharply, the surface ecology has been unbalanced, urban floods have occurred, and environmental problems have become increasingly serious.

[0003] Research on the permeability and purification of green and environmentally friendly floors can effectively play a role in water resource conservation, ecological sustainability and environmental protection. The permeable floor can be used to make full use of water resources by allowing rainwater to infiltrate the soil or return to rivers, so that rainwater can be recycled and turned into treasure.

[0004] Therefore, how to design a floor that can beautify the urban environment while saving resources, reducing costs, improving permeability and bearing capacity, and utilizing rainwater is a technical problem that needs to be solved urgently. Utility Model Content

[0005] The purpose of the utility model is to provide an environmentally friendly floor with water permeability and purification function to overcome the above-mentioned shortcomings and deficiencies of the prior art.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An environmentally friendly floor comprises a concrete permeable surface layer and a crushed stone layer from top to bottom. The concrete permeable surface layer is laid on the crushed stone layer. The concrete permeable surface layer is composed of a number of floor tiles with a porosity of 15%-25% arranged and laid in a matrix shape.

[0008] The floor tile is provided with a drainage component that runs through the body, and the drainage component includes a pipe body, a filler and two grilles. The upper and lower end surfaces of the pipe body are flush with the upper and lower surfaces of the concrete permeable surface layer. The two grilles are respectively arranged at the two ends of the pipe body. The pipe body is filled with a particle size of 1-2 mm and a specific surface area of ​​100-1000m 2 / g of activated carbon.

[0009] In one embodiment of the present invention, the gravel layer is made of one or more of limestone, basalt, sandstone and Danxia rock.

[0010] In one embodiment of the present invention, the thickness ratio of the floor tiles to the crushed stone layer is 1:3-4:6.

[0011] In one embodiment of the present invention, the drainage assembly and the floor tiles are cast in one piece.

[0012] In one embodiment of the present invention, the pores of the grid are less than 1 mm.

[0013] In one embodiment of the present invention, a filter screen with a pore size of 0.01-0.05 mm is provided at the upper end of the tube body near the grille.

[0014] In one embodiment, the gravel layer includes a skeleton structure and fillers, wherein the skeleton structure is formed by interlocking of large-size gravel of 10mm-20mm, and the fillers are filled in the gaps between the large-size gravel of 10mm-20mm.

[0015] In one embodiment, the filler is gravel of a single particle size, and the particle size range is 1-2 mm.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the utility model include:

[0017] 1. The concrete permeable surface layer is laid directly on the gravel layer. Since the gravel layer has a solid structure, uniform texture and high density, it has a good receptor for the bearing capacity acting on the concrete permeable surface layer, and the floor tiles are not easy to collapse. At the same time, the gaps between the gravel in the gravel layer can quickly allow rainwater to flow into the soil.

[0018] 2. The porosity of the floor tiles is 15%-25%, which greatly improves the water permeability. The floor tiles are equipped with drainage components that run through the body. Rainwater that cannot be discharged from the floor in time is discharged into the ground through the drainage components. The drainage components improve the drainage capacity of the floor and purify pollutants in rainwater runoff.

[0019] 3. The concrete permeable surface layer can achieve rapid installation of the floor through splicing floor tiles, which is convenient for construction, short in construction period, and greatly improves the laying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] See also Figure 1-2 The environmentally friendly floor with water permeability and purification function comprises a concrete permeable surface layer and a crushed stone layer from top to bottom. The concrete permeable surface layer is laid on the crushed stone layer. The concrete permeable surface layer is composed of a plurality of floor tiles with a porosity of 15%-25% arranged in a matrix. The floor tiles are provided with a drainage component that runs through the body. The drainage component comprises a pipe body, a filler and two grilles. The upper and lower end surfaces of the pipe body are flush with the upper and lower surfaces of the concrete permeable surface layer. The two grilles are respectively arranged at the two ends of the pipe body. The pipe body is filled with a particle size of 1-2mm and a specific surface area of ​​100-1000m 2 / g of activated carbon.

[0029] The crushed stone layer is made of limestone, and the crushed stone layer includes a skeleton structure and fillers. The skeleton structure is formed by interlocking large-grained limestone of 10mm-20mm and laid on the soil, and the fillers are filled in the gaps between the large-grained crushed stones of 10mm-20mm. The fillers are made of single-grained limestone with a particle size of 1mm. The single-grained filled large-grained cement-stabilized crushed stone base uses a single-grained filler to fill the skeleton. After compaction, the overall base material has a large porosity inside, which is conducive to the timely discharge of rainwater infiltrated from the surface, slowing down the damage caused by rainwater to the base, and extending the service life of the base.

[0030] The thickness ratio of the floor tiles to the gravel layer is 1:3, which is used to improve the bearing capacity of the floor. The drainage assembly is cast integrally with the floor tiles. In order to confine the activated carbon in the tube body, the pores of the grille are less than 1mm, and the grille can block large suspended matter. In order to further prevent polluted particles from clogging the tube body, a filter with a pore size of 0.01mm is provided at the upper end of the tube body near the grille, and the filter is removable for replacement and maintenance.

[0031] Example 2

[0032] Another type of permeable and environmentally friendly flooring includes a concrete permeable surface layer and a crushed stone layer in order from top to bottom. The concrete permeable surface layer is laid on the crushed stone layer. The concrete permeable surface layer is composed of a number of floor tiles with a porosity of 15%-25% arranged in a matrix. The floor tiles are provided with a drainage component that runs through the body. The drainage component includes a pipe body, a filler and two grilles. The upper and lower end faces of the pipe body are flush with the upper and lower surfaces of the concrete permeable surface layer. The two grilles are respectively arranged at the two ends of the pipe body. The pipe body is filled with a particle size of 1-2mm and a specific surface area of ​​100-1000m 2 / g of activated carbon.

[0033] The crushed stone layer is made of basalt, and the crushed stone layer includes a skeleton structure and fillers. The skeleton structure is formed by interlocking large-grained limestone of 10mm-20mm and laid on the soil, and the fillers are filled in the gaps between the large-grained crushed stones of 10mm-20mm. The fillers are made of single-grained limestone with a particle size of 2mm. The single-grained filled large-grained cement-stabilized crushed stone base uses a single-grained filler to fill the skeleton. After compaction, the overall base material has a large porosity inside, which is conducive to the timely discharge of rainwater infiltrated from the surface, slowing down the damage caused by rainwater to the base, and extending the service life of the base.

[0034] The thickness ratio of the floor tiles to the gravel layer is 4:6, which is used to improve the bearing capacity of the floor. The drainage assembly is cast integrally with the floor tiles. In order to confine the activated carbon in the pipe body, the pores of the grille are less than 1mm, and the grille can block large suspended matter. In order to further prevent polluted particles from clogging the pipe body, a filter with a pore size of 0.05mm is provided at the upper end of the pipe body near the grille. The filter is detachable and fixed to the grille by fasteners for replacement and maintenance.
