AI Technical Summary
Existing permeable bricks are prone to loosening, affecting pedestrian or vehicle passage, and rainwater cannot drain in time during heavy rain, leading to pore blockage and reduced permeability.
The permeable bricks are spliced using a mortise and tenon structure, and a linear drainage ditch is set between the permeable bricks, extending down to the crushed stone cushion layer. A fine stone concrete foundation layer is laid, which is then fixed with a dry-hardened cement mortar layer, forming a structure consisting of a compacted soil layer, a crushed stone cushion layer, a fine stone concrete layer, and a dry-hardened cement mortar layer.
It effectively prevents bricks from loosening, ensures road stability, improves water permeability, drains rainwater in a timely manner, and extends the service life of the road.

Abstract
Description
Technical Field
[0001] This utility model relates to a permeable pavement structure, and more particularly to a permeable pavement structure for residential communities. Background Technology
[0002] The construction of sponge cities has already achieved remarkable results in several pilot cities. In the future, with the deepening of ecological civilization construction and the implementation of "dual-carbon" goals, sponge city construction will become an important development direction for new urbanization. Its technological system will continue to improve, and its application scope will continue to expand, providing crucial support for building livable, resilient, and smart cities. The concept of sponge city construction has emerged in response to this need. Its core lies in constructing a virtuous cycle of the urban water ecosystem through various technological means such as infiltration, retention, storage, purification, utilization, and drainage. This new urban development model can not only effectively alleviate urban flooding and improve water resource utilization efficiency, but also improve the urban ecological environment and promote harmonious coexistence between humans and nature.
[0003] Permeable bricks, as a type of permeable pavement, are frequently used in the construction of sponge cities. Permeable bricks primarily function by rapidly infiltrating rainwater through their porous structure, reducing surface runoff and alleviating pressure on drainage systems.
[0004] The main problems with current permeable bricks are as follows:
[0005] 1. After a period of time, the road may become loose, affecting the passage of pedestrians or vehicles;
[0006] 2. In general, permeable brick roads in residential areas have drainage ditches on both sides of the road or direct drainage into the green belts on both sides. However, during periods of heavy rainfall, rainwater cannot be drained in time. Rainwater mixed with dust on the surface of the bricks can easily block the pores of the permeable bricks, resulting in a decrease in water permeability. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide a permeable pavement structure for residential communities, which not only has good permeability and relieves the pressure on the drainage system, but also effectively prevents the bricks from loosening, prevents uneven road settlement, and extends the service life of the road.
[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is to provide a permeable pavement structure for residential communities, which includes, from bottom to top: a compacted soil layer, a crushed stone cushion layer, a fine stone concrete layer, a dry hard cement mortar layer, and multiple permeable bricks laid flat, with adjacent permeable bricks spliced together using a tenon and mortise structure.
[0009] Furthermore, a linear drainage ditch is formed between the permeable bricks, a drainage ditch cover is provided above the linear drainage ditch, and the linear drainage ditch extends through to the crushed stone cushion layer and a fine stone concrete base layer is laid below the linear drainage ditch.
[0010] Furthermore, the strength grade of the fine aggregate concrete base layer is C20 to C30.
[0011] Furthermore, the thickness of the crushed stone cushion layer is 80mm to 150mm.
[0012] Furthermore, the thickness of the fine aggregate concrete layer is 100–180 mm, and the concrete strength grade is C25–C35.
[0013] Furthermore, the thickness of the dry-hardened cement mortar layer is 30 mm.
[0014] Compared with the prior art, the present invention has the following advantages: The permeable pavement structure for residential communities provided by the present invention uses permeable bricks with mortise and tenon joints, which not only has a good permeability effect and relieves the pressure on the drainage system, but also effectively prevents the bricks from loosening; a dry-hardened cement mortar layer is used under the permeable bricks to bond and fix the permeable pavement, and below the dry-hardened cement mortar layer is a fine stone concrete layer and a crushed stone cushion layer, which plays a role in leveling and ensuring the strength of the foundation, preventing uneven settlement of the road, and extending the service life of the road.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Figure 1 This is a schematic diagram of the permeable pavement structure of this utility model for use in residential communities; Figure 2 This is a schematic diagram of the splicing of two adjacent permeable bricks in the permeable pavement structure of this utility model.
[0021] Please see Figure 1 and Figure 2The permeable pavement structure for residential communities provided by this utility model includes, from bottom to top: a compacted soil layer 1, a crushed stone cushion layer 2, a fine stone concrete layer 3, a dry hard cement mortar layer 4, and multiple permeable bricks 5 laid flat. Adjacent permeable bricks 5 are spliced together using a mortise and tenon structure.
[0022] The permeable pavement structure for residential communities provided by this utility model adopts permeable bricks with mortise and tenon structure (this type of permeable brick can be molded in the factory), that is, two bricks are embedded together in the form of tongue and groove anchoring, which can effectively prevent the bricks from loosening.
[0023] The permeable pavement structure for residential communities provided by this utility model has a crushed stone subbase 2 with a thickness of 80mm to 150mm, preferably 100mm; the fine stone concrete layer 3 has a thickness of 100mm to 180mm, determined according to the parking load, and the concrete grade is not lower than C20, preferably C25 to C35.
[0024] The permeable pavement structure for residential communities provided by this utility model uses a dry-hardened cement mortar layer 4 under the permeable bricks 5 for bonding and fixing the permeable pavement; below the dry-hardened cement mortar layer 4 is a fine stone concrete layer 3, and below the fine stone concrete layer 3 is a crushed stone cushion layer 2, which serves to level the surface and ensure the strength of the foundation, preventing uneven settlement of the road; the bottom layer is a compacted soil layer 1; it not only has a good permeability effect and relieves the pressure on the drainage system, but also prevents uneven settlement of the road and extends the service life of the road.
[0025] The present invention provides a permeable pavement structure for residential communities, wherein a linear drainage ditch 6 is formed between the permeable bricks 5, a drainage ditch cover plate 7 is provided above the linear drainage ditch 6, and the linear drainage ditch 6 extends through to the crushed stone cushion layer 2 and is laid with a fine stone concrete base layer 8, the concrete grade being C20 to C30.
[0026] In addition to drainage ditches along both sides of the road, a linear drainage ditch 6 is installed in the middle of the permeable bricks 5. This ditch is relatively small and will not affect the overall aesthetics of the permeable pavement. The linear drainage ditch 6 connects to the community's drainage pipes and ultimately flows into the municipal drainage system to promptly drain rainwater. A fine aggregate concrete base layer 8, with a concrete grade of no less than C20, is installed beneath the linear drainage ditch 6 to protect it and prevent breakage and deformation.
[0027] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
