The utility model provides a rainwater permeable water storage device suitable for laying on the impermeable ground. By laying the hollow brick 1 on the impermeable structure 6, when there is a heavy rain, part of the rainwater in the large area of the square will penetrate into the hollow brick 1. All the rainwater will flow into the rainwater pipe network, which buffers and reduces the pressure of the municipal drainage pipe network. It can also effectively remove some N, P, grease, heavy metals and other pollutants in the rainwater runoff, reducing the pollution of rainwater flowing into the river.

In addition, on sunny days, especially in summer, large-area hard pavements in squares cause serious heat island effects, making it very uncomfortable for pedestrians to move around in squares. The water in the hollow brick 1 can evaporate slowly, reduce the ground temperature, and eliminate the heat island effect.

The utility model can be used in places such as roofs of buildings, roads in residential quarters, sidewalks, basement roofs, and squares.

A rainwater permeable water storage device suitable for laying on impermeable ground provided by the utility model has the following characteristics:

1. Use permeable concrete materials to prefabricate the hollow brick 1 of 300mm (length) × 300mm (width) × 200mm (height). The specifications of the hollow brick 1 can also be changed to other sizes according to the needs of the design;

2. The wall thickness of the hollow brick 1 is 30mm. You can also calculate the strength, select the wall thickness, and select the mix ratio of concrete cement and mortar according to the bearing capacity required by pedestrians or vehicles;

3. The cavity 2 of the hollow brick 1 is filled with spongy soil blocks, that is, the volume ratio of compost:sand:black soil=3:2:5, high water permeability and water storage soil;

4. Openings 7 are set in the center around the hollow brick 1. For the hollow brick 1 of 300mm (length) × 300mm (width) × 200mm (height), the size of the opening 7 is 100mm (length) × 50mm (height), so as to facilitate the interpenetration of rainwater after laying ;

5. The pedestrian surface of the hollow brick 1 can adopt the embossed pattern 4. In order to improve the water permeability, the pedestrian surface can reserve water permeable holes 5 (also called micro-perforation) with a diameter not greater than 3mm. Each hollow brick 1 is provided with about 50 water permeable holes. 5. The effective permeable area of the perforation is about 2cm ² , which strengthens the permeable effect;
