This utility model discloses a self-cleaning sponge urban permeable pavement, comprising, from top to bottom, a permeable brick layer, a self-cleaning layer, a medium sand layer, a gravel layer, and a base soil layer. The permeable brick layer is constructed by laying a plurality of permeable bricks, with gaps between adjacent bricks and a filter screen positioned above the gaps. A rectangular water storage pipe with permeable holes is positioned within the gravel layer. A water reservoir is located on the side of the permeable pavement, connected to the reservoir via a drainage pipe. A blind seepage pipe is inserted through the base soil layer, connecting to the reservoir. The internal pores of this utility model are not easily clogged, and rainwater can be recycled.

[0004] The above technical solutions have generally poor strength and stability during use. When subjected to heavy pressure, the water storage tank is prone to cracking, which reduces the service life of the permeable asphalt pavement of the pedestrian walkway.

The cross section of the mixed brick pavement 1 is an inverted U-shaped, which limits the subsequent parts and uses its special shape to strengthen the connection strength. An anti-cracking mechanism 2 is provided inside the mixed brick pavement 1. The anti-cracking mechanism 2 includes a reinforcement brick layer 201 fixedly connected to the top wall of the mixed brick pavement 1. A plurality of water leakage gaps 202 are opened at the top of the mixed brick pavement 1, and the water accumulated on the road is drained through the water leakage gaps 202. The bottom end of the reinforcement brick layer 201 is fixedly connected to a buffer layer 203. The buffer layer 2 03 is fixedly connected to the bottom of the reinforced brick pavement 1 with a steel reinforcement layer 204, and the top of the buffer layer 203 is provided with a plurality of first connecting grooves 206, the interior of the first connecting groove 206 is clamped with a first connecting block 205, and the first connecting block 205 is fixedly connected to the bottom of the reinforced brick layer 201, and the internal structural strength of the concrete brick pavement 1 is reinforced by the cooperation of the first connecting block 205 and the first connecting groove 206, and the bottom of the buffer layer 203 is provided with a plurality of second connecting grooves 208, the interior of the second connecting groove 208 is clamped with a second connecting block 207, and the second connecting block 207 is fixedly connected to the reinforced brick layer 204. The top of the second connecting groove 208 is fixedly connected, the second connecting groove 208 is staggered with the first connecting groove 206, and the space provided by the first connecting groove 206 and the second connecting groove 208 to provide road deformation is reduced to reduce cracking, and the structural strength of the concrete pavement 1 and the anti-cracking mechanism 2 is strengthened again to prevent cracking. The bottom end of the steel reinforcement layer 204 is fixedly connected to the geogrid layer 4, and the bottom end of the geogrid layer 4 is fixedly connected to the base layer 5. The anti-cracking mechanism 2 is restricted by the cooperation of the concrete pavement 1 and the base layer 5. The top cross-section of the leakage gap 202 is V-shaped, and the bottom end of the leakage gap 202 is fixed. A drainage pipe 3 is fixedly connected, and the shape of the leakage gap 202 is used to prevent debris from clogging the leakage gap 202 and facilitate cleaning by personnel. At the same time, the drainage pipe 3 is used to discharge the accumulated water. Through the cooperation of the concrete brick pavement 1 and the anti-cracking mechanism 2, the strength of the structure is initially strengthened by the cooperation of the reinforced brick layer 201, the buffer layer 203 and the steel reinforcement layer 204, and the staggered distribution of the first connecting groove 206 and the second connecting groove 208 is used to further improve the stability of the structure. Therefore, on the basis of maintaining the original drainage function of the leakage gap 202, the anti-cracking function is added to provide the practicality of the structure.

[0025] Refer to the instruction manual Figure 1-4The inner wall of the drain pipe 3 is fixedly connected with a first turbulent plate 8, and a second turbulent plate 7 is arranged below the first turbulent plate 8.

Through the cooperation of the drain pipe 3, the second turbulent plate 7 and the first turbulent plate 8, the cooperation between the second turbulent plate 7 and the first turbulent plate 8 is used to reduce the diameter of the drain pipe 3 in turn, thereby accelerating the speed of the water flow inside the drain pipe 3, and then improving the drainage speed of the drain pipe 3.

[0026] This utility works as follows:

[0027] Refer to the instruction manual Figure 1-4 During rainfall, rainwater enters the interior of the drain pipe 3 through the leaking gap 202, and the V-shaped structure at the top of the leaking gap 202 is used to prevent debris from clogging the leaking gap 202 and facilitate cleaning by personnel. The second turbulent plate 7 and the first turbulent plate 8 are used in conjunction with each other to successively reduce the diameter of the drain pipe 3, thereby accelerating the speed of the water flow inside the drain pipe 3, and then increasing the drainage speed of the drain pipe 3 to achieve the drainage function of the structure. Subsequently, when the concrete brick pavement 1 is in use, the pressure of the anti-cracking mechanism 2 is limited by the shape of the concrete brick pavement 1. The force is dispersed, so that the pressure on the anti-cracking mechanism 2 is more dispersed, thereby maintaining the structure of the anti-cracking mechanism 2 without deformation, and using the reinforcement plate 6 to disperse the pressure inside the anti-cracking mechanism 2, and then using the reinforcement brick layer 201, the buffer layer 203 and the steel reinforcement layer 204 to preliminarily strengthen the strength of the structure, and using the staggered distribution of the first connecting groove 206 and the second connecting groove 208 to further improve the stability of the structure, thereby increasing the anti-cracking function on the basis of maintaining the original drainage function of the leakage gap 202 to provide practicality of the structure.
