The water permeable bricks 1 have good water permeability, so that rainwater can rapidly permeate into the ground through the water permeable bricks 1 in rainy days to supplement soil water and underground water, so that no water is accumulated after rain, and pedestrians can conveniently pass through; in a sunny climate, the moisture accumulated in the bricks balances the surface temperature through evaporation.

The water permeable brick 1 can be any one of common water permeable bricks, colored stone epoxy through-body water permeable bricks, ecological sand-based water permeable bricks and the like, in order to effectively prevent the water permeable brick 1 from being blocked, a self-cleaning water permeable brick is preferably adopted, the self-cleaning water permeable brick can be directly purchased from Beijing Jinjiangshundao building materials Co., Ltd, a photocatalyst technology is applied to the water permeable brick, the photocatalyst can generate a photocatalytic reaction under the irradiation of light to generate free hydroxyl and active oxygen with extremely strong oxidation capability, and the free hydroxyl and the active oxygen can be oxidized and decomposed into various organic compounds and partial inorganic substances, so that the water permeable brick has extremely strong functions of antifouling and self-cleaning and water purification, can effectively prevent the pores of the water permeable brick 1 from being blocked, further prolong the service life of the water permeable brick 1, and can reduce the problem of soil pollution caused by water quality to a certain degree.

In addition, if the buckling is not tight between the brick and the brick, the phenomenon of looseness easily occurs, so that the brick surface is broken due to uneven stress, and after years of use, some stagnant water can exist in the gap between the brick and the brick, so that the looseness of the permeable brick 1 on the sidewalk is accelerated, the service life of the sidewalk is shortened, and the effective drainage of the permeable brick 1 is not facilitated. Therefore, the gaps between the adjacent permeable bricks 1 which are mutually abutted are filled with permeable cement concrete. The cement concrete that permeates water can strengthen the laying fastness of brick 1 that permeates water, and in addition, the cement concrete that permeates water is the concrete that the void ratio is 15% ~ 25%, and the cement concrete that will permeate water is laid and can be increased the permeable area, the infiltration area on road surface on the pavement road surface, can be fast with rainwater infiltration to the soil in, when supplying moisture for vegetation, with the cooperation of brick 1 that permeates water use, can reduce the possibility of pavement ponding, and then be favorable to the pedestrian current.

As shown in fig. 1, if there is a low-lying area on the pavement of the sidewalk, the accumulated water will gather in the low-lying area after heavy rain, and at this time, if the water is drained completely by the water permeable bricks 1, it takes a long time, and it is not beneficial to the long-term use of the water permeable bricks 1, so that the gaps 11 can be opened at the four corners of the water permeable bricks 1, the gaps 11 of the water permeable bricks 1 laid adjacently enclose a closed water outlet 111, the water outlet 111 is internally provided with a drainage mechanism 3, and a plurality of drainage mechanisms 3 can be provided.

As shown in fig. 1, the shape of the drainage opening 111 formed by the notch 11 may be any shape such as circular, square, etc., and the drainage opening 111 in this embodiment is circular, because the circular drainage opening 111 can be attached to the outer wall of the drainage mechanism 3 more tightly, so that the accumulated water is further ensured not to penetrate into the gap between the drainage opening 111 and the drainage mechanism 3, and the water permeable brick 1 is protected.

As can be seen from fig. 1 and 2, the drainage mechanism 3 includes a drainage assembly 2 and a water pipe 24, the drainage assembly 2 is installed inside the drainage opening 111, the end of the drainage assembly 2 is communicated with the water pipe 24, and one end of the water pipe 24 far away from the drainage assembly 2 extends into the soil. Rainwater can directly flow into the water delivery pipeline 24 through the drainage component 2, and then the purpose of collecting rainwater can be achieved while timely draining water on the pavement of the pedestrian path.

As shown in fig. 2, the drainage assembly 2 may adopt any structure that can make the accumulated water on the pavement of the sidewalk smoothly pass through, such as a floor drain, a siphon drainage pipe fitting, etc., in order to better filter the accumulated water, the drainage assembly 2 in this embodiment adopts a filter net sleeve 22, the filter net sleeve 22 is embedded into a drainage port 111 formed by the notch 11, the outer wall of the filter net sleeve 22 is tightly attached to the inner wall of the drainage port 111, a filter net 221 is fixedly connected inside the filter net sleeve 22, and one end of the filter net sleeve 22 close to the ground is communicated with the water pipe 24.
