DETAILED DESCRIPTION
[0021] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in conjunction with the drawings and specific embodiments.
[0022] Referring to Figures 1-4 The utility model provides: a kind of hard road with anti-blocking water-permeable pavement structure, including water permeable layer 3 and the drainage ditch layer 8 being arranged in water permeable layer 3 side, water permeable layer 3 is the key part in road structure, design is used to receive from such as rainwater or road surface water moisture, and allow these moisture to penetrate to lower layer by its structure. Water permeable layer 3 is usually made of water-permeable material, such as water-permeable concrete, these materials allow moisture to penetrate but prevent soil particles and other impurities from passing. One end of drainage ditch layer 8 is connected with drainage pipe 12 for introducing water into underground, gravel layer 4 for filtering impurities in water is arranged above water permeable layer 3, detachable filter frame 9 is arranged in drainage ditch layer 8, the central position of filter frame 9 is recessed to the inside and forms cavity for water passing with drainage ditch layer 8, drainage ditch layer 8 is used to collect and guide the moisture that penetrates from water permeable layer 3, ensure that moisture can flow smoothly to drainage pipe 12. Drainage pipe 12 is composed of longitudinally arranged and transversely arranged pipe, and a plurality of through holes 121 for water passing are distributed on drainage pipe 12, and isolation net is sleeved outside drainage pipe 12.
[0023] Through the synergies of water permeable layer 3, gravel layer 4, drainage ditch layer 8, filter frame 9, drainage pipe 12 and isolation net, effective collection, filtration and discharge of road surface moisture are realized, and the blockage of drainage system is prevented, and the water permeability and drainage efficiency of road are improved.
[0024] The middle part of filter frame 9 is recessed inward, and forms cavity for water passing with drainage ditch layer 8, and one end of drainage pipe 12 is arranged at the central position of drainage ditch layer 8, when water flows into drainage ditch layer 8, water will overflow to the water inlet of drainage pipe 12, and impurities will remain at the bottom of filter frame 9, when the impurities in filter frame 9 are higher than the height of drainage pipe 12, water can still flow into drainage pipe 12 from the upper part of filter frame 9, so that the problem of easy blockage of water inlet of pipe is solved.
[0025] A removable grid layer 10 is provided on top of the drainage channel layer 8, and a filter plate 11 for filtering larger impurities in the water is provided on top of the grid layer 10. The grid layer 10 is mainly used to support the filter plate 11 and provide a framework or structure for easy disassembly and maintenance when needed. In addition, the grid layer 10 itself can also serve as a preliminary filter layer to prevent large debris from falling directly into the drainage channel layer 8. The grid layer 10 is usually made of strong and durable materials such as metal or plastic, which can withstand the weight of pedestrians and vehicles above while maintaining the structural integrity. The grid layer 10 has openings of moderate size that can block larger impurities but allow water to flow through. The filter plate 11 is usually made of water-permeable materials that allow water to flow through but can block larger impurities.

[0026] A gravel cushion layer 2 is provided below the water-permeable layer 3, and a stone base layer 1 for preventing road settlement is provided at the bottom of the gravel cushion layer 2. The stone base layer 1 is the load-bearing layer of the road structure, used to disperse and support the weight of the layers above to prevent road settlement. The stone base layer 1 is usually composed of large, solid stones that are closely arranged to form a stable support structure. The gaps between the stones help with drainage but are not sufficient to cause significant settlement of the road structure. Part of the gravel cushion layer 2 can fill the gaps in the stone base layer 1, and the gravel cushion layer 2 serves as a transition and buffer, which can disperse the weight of the water-permeable layer 3 above to the stone base layer 1 below while providing certain drainage performance. The gravel cushion layer 2 is composed of different sizes of gravel particles, and the gaps between these particles allow water to penetrate and guide water to the lower layer. In addition, part of the gravel cushion layer 2 can fill the gaps in the stone base layer 1, further enhancing the stability of the road structure. A permeable brick layer 5 for water permeability is laid on top of the gravel layer 4, and the height of the permeable brick layer 5 is 10-20 cm. The permeable brick layer 5 is made of water-permeable materials such as water-permeable concrete bricks or water-permeable ceramic bricks.

[0027] A cement support layer 6 for supporting the road is laid on top of the permeable brick layer 5, and the height of the cement support layer 6 is not greater than 50 cm.

A permeable asphalt surface layer 7 is laid on top of the cement support layer 6, and the height of the permeable asphalt surface layer 7 is 3-10 cm. The permeable asphalt surface layer 7 is made of water-permeable asphalt materials that have a porous structure that allows water to penetrate. When rainwater or water on the road surface falls onto the permeable asphalt surface layer 7, water penetrates through its porous structure to the cement support layer 6 and permeable brick layer 5 below.
