[0002] The connection between the existing permeable bricks and their adjacent bricks is not tight enough. After the laid bottom surface is used for a period of time, the bricks are prone to looseness, which is not conducive to walking. Moreover, the current permeable bricks often only have the function of seeping water, that is, infiltrating rainwater into the ground, but do not have the ability to transport and store water. When the rain is heavy, there will be a lot of water accumulation on the sidewalk paved with permeable bricks.

[0003] After retrieval, the patent with the authorization number of CN209816596U in China discloses a permeable brick for a sponge city, which solves the defects of single function and insecure connection of the permeable brick for a sponge city in the prior art. A horizontal drainage hole is opened at the bottom of the permeable brick body, a vertical drainage hole is opened in the middle of the permeable brick body, the bottom of the vertical drainage hole is connected with the horizontal drainage hole, a horizontal water trough is arranged on the top surface of the permeable brick body, one end of the horizontal water trough is connected with the top of the vertical drainage hole, grooves or convex blocks are respectively arranged on the side surfaces of the permeable brick body. When a groove is arranged on one side surface of the two opposite side surfaces of the permeable brick body, a convex block should be arranged on the other side surface. Inclined surfaces inclined inwards are respectively arranged on the lower sides of the two side surfaces not penetrated by the horizontal drainage hole, and a plurality of water inlet grooves are respectively arranged on the upper sides of the two side surfaces not penetrated by the horizontal drainage hole. The utility model is used for hardening the ground and seeping water.

[0028] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0029] Among them, the same reference numerals in the drawings all refer to the same components.

[0030] The usage method of the present utility model is as follows:

[0031] As Figure 1-4 shown, a kind of urban permeable brick includes a permeable brick body 1 and a filter net 2. A central water tank 5 penetrating up and down is provided in the middle of the permeable brick body 1, and a bottom water tank 6 is provided at the bottom of the permeable brick body 1. The bottom water tank 6 horizontally penetrates the bottom surface of the permeable brick body 1. Multiple permeable brick bodies 1 are arranged in sequence with their end faces abutted against each other, so that the bottom water tanks 6 can communicate with each other. All the bottom water tanks 6 are connected and combined to form a whole network-shaped water storage system. When it rains, the rainwater falls on the permeable brick and converges into the bottom water tank 6 through the central water tank. Since the bottom water tank 6 is in large-area contact with the soil, the seepage efficiency is ensured. The bottom water tank 6 and the surface water tank 3 are vertically connected through the central water tank 5. A certain amount of rainwater can be stored in the ground water tank 6 and the central water tank 5, increasing the water storage capacity of the permeable brick.

[0032] Further, as Figure 3 shown, there is a vertical drainage hole 4 penetrating up and down in the surface water tank 3, and the other end of the vertical drainage hole 4 is communicated with the bottom water tank 6. A small part of the rainwater can quickly flow into the ground water tank through the vertical drainage hole 4, realizing the rapid transfer of surface water accumulation.

[0033] Further, as Figure 1-5 shown, a filter net concave platform 7 connected to the filter net 2 is provided in the center of the permeable brick body 1. The thickness of the filter net 2 is less than the depth of the filter net concave platform 7. Preferably, the filter net 2 is provided with dense round holes. The rainwater can converge on the filter net and flow into the bottom water tank 6 below the permeable brick through the central water tank 5 in the lower part of the filter net to contact the soil.

[0034] Further, as Figure 3, the surface water tank 3 communicates with the filter concave platform 7 and is radially distributed evenly along the circumference of the filter concave platform 7. The rainwater in the surface water tank 3 can quickly converge onto the filter net 2 connected to the filter concave platform 7.

[0035] Furthermore, the shape of the permeable brick body 1 is a regular hexagon. Preferably, fillets are provided at the vertical edge positions, as Figure 6-7 , the edge fillets of 3 spliced permeable brick bodies 1 form a vertical drainage channel, which can further improve the drainage capacity.

[0036] Furthermore, the bottom water tanks 6 are radially distributed evenly along the circumference of the central water tank 5. After splicing, all the bottom water tanks 6 can communicate with each other to form a water network, increasing the rainwater dredging capacity.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
