Description

Technical Field

[0001] The utility model relates to the technical field of piston rod processing, in particular to a base layer water-permeable structure for a municipal road. Background Art

[0002] With the rapid development of urbanization, the amount of impermeable hard pavement in cities has increased significantly, and this impermeable hard ground has brought many problems to the urban environment. The base permeable structure of municipal roads is an important part of road construction. It plays a significant role in improving the drainage performance of roads, reducing road surface waterlogging, and alleviating the urban heat island effect.

[0003] The patent application with reference publication number CN111139703A discloses a permeable road structure without road humps on the road surface, comprising a roadbed, a cushion layer laid on the roadbed, a base layer laid on the cushion layer, a surface layer laid on the base layer, and an impermeable seal layer laid between the base layer and the surface layer; the impermeable seal layer is an arched structure with a high middle and low sides, the upper surface of the surface layer is a horizontal plane, and the surface layer is made of porous asphalt mixture; on rainy days, rainwater will directly penetrate into the road after contacting the road surface, instead of flowing laterally along the road humps of traditional road surfaces, preventing rainwater from flowing on the road surface to form a water film, and eliminating the road humps, so that the adverse effects of the road humps on driving stability no longer exist, making driving more comfortable and smooth. In summary, the invention can make driving smoother and safer to the greatest extent, prevent rainwater from flowing on the road surface to form a water film, and thus ensure driving.

[0004] As shown in the above-mentioned prior art, although the permeable road structure in the prior art can allow rainwater to penetrate the road surface and prevent rainwater from forming a water film on the road surface to a certain extent, making driving smoother, when there is heavy rain in the rainy season, such road structure does not have a drainage system, which will still cause rainwater to accumulate on the road surface, thereby affecting the normal traffic on the road.

[0005] Therefore, it is necessary to provide a base permeable structure for municipal roads to solve the above technical problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] This utility model provides two technical solutions:

[0033] Figures 1 to 3 A first embodiment is shown: a base permeable structure for a municipal road, comprising:

[0034] Planar layer 2, set on top of the soil layer to ensure the flatness of the road paving;

[0035] The impermeable structural layer 3 is arranged on top of the plane layer 2 to prevent water from penetrating the soil layer, thus avoiding soil softening and instability of the road foundation;

[0036] A filling pad layer 4 is provided on top of the impermeable structural layer 3, and a drainage pipe 15 is provided on the inner wall of the filling pad layer 4;

[0037] A permeable base layer is provided on top of the filling padding layer 4, and a drainage channel 16 is installed between the permeable base layers;

[0038] There are multiple drain covers 5, all of which are fixed to the top of the drainage channel 16. Drain pipes 6 are fixed below the drainage channel 16 in the same number as the number of drain covers 5. The lower ends of the drainage pipes 6 are connected to the upper ends of the drain pipes 15.

[0039] A filter assembly is provided on the inner wall of the drainage channel 16 and below the drain cover 5, and is used for preliminary filtering of water entering the drainage channel 16;

[0040] The fine filter 7 is arranged at the upper end of the drainage pipe 6 and is used for secondary filtering of the water entering the drain pipe 15.

[0041] The permeable base layer includes a gravel layer 9 arranged on top of the filling padding layer 4, and a plurality of permeable bricks 8 are laid on top of the gravel layer 9.

[0042] The filter assembly includes a fixed net 10 fixed to the inner wall of the drainage channel 16 , and a coarse gravel layer 1 is arranged above the fixed net 10 .

[0043] Drainage grooves 11 are provided on both sides of the drainage channel 16 close to the gravel layer 9 , and the drainage channel 16 is communicated with the gravel layer 9 through the drainage grooves 11 .

[0044] Figures 1 to 3 The second embodiment is shown. The main difference from the first embodiment is that a transverse anti-skid groove 12 is opened on the top of the permeable brick 8 in the direction corresponding to the drain cover 5. The anti-skid groove 12 is used to prevent safety hazards caused by slippery road surface, and the anti-skid groove 12 can guide water in the groove to the drain cover 5.

[0045] There is a certain anti-crack gap 14 between every two permeable bricks 8, and the anti-crack gap 14 is filled with high-performance concrete 13; this helps to reduce cracks caused by thermal expansion and contraction, and improves the durability of the road structure.

[0046] Working principle:

[0047] When it rains, part of the rainwater directly penetrates the permeable bricks 8 and enters the gravel layer 9. The water in the gravel layer 9 is discharged to the drainage channel 16 through the drain trough 11; part of the rainwater flows to the drainage cover 5 through the anti-skid groove 12 on the permeable bricks 8, flows out of the fixed net 10 after being filtered by the coarse crushed stone layer 1, enters the bottom of the drainage channel 16, and flows to the drainage pipe 15 after being filtered by the fine filter screen 7. Finally, the rainwater that has been filtered layer by layer is discharged from the drainage pipe 15; this prevents dirt, impurities and garbage on the road from being discharged along with the rainwater, polluting the water quality and endangering the ecological environment.
