And, the volume of the drainage cavity 9 can be made larger in a matched manner, so that the urban requirement of large rainfall is met.

Example 4

This embodiment is different from embodiment 1 in that, as shown in fig. 10, the tile cover 4 includes: a light-transmitting plate 19 arranged opposite to the solar panel 6, and a water-permeable plate 20 arranged opposite to the sealing float 7; the light-transmitting plate 19 is made of glass, the water-permeable plate 20 is made of water-permeable concrete, and the water inlet 5 is arranged on the water-permeable plate 20; the porous disk 20 with its lower surface of light-passing board 19 is provided with the annular arch 21 that the chamber wall cooperation in its holding chamber 2 of brick base member 1 links to each other, porous disk 20 with its two of light-passing board 19 are connected the face and are the plane. The brick cover 4 is composed of the light-transmitting plate 19 made of glass and the water-permeable plate 20 made of permeable concrete, so that the efficiency of rainwater entering the brick base body 1 and the accommodating cavity 2 for accommodating water can be effectively improved. When avoiding setting up brick lid 4 wholly to light-passing board 19, the rainwater can only get into pervious concrete brick 16 through water inlet 5, leads to when water inlet 5 is sealed by sealed cursory 7, appears the problem of surface gathered water easily. More importantly, the permeable plate 20 made of the permeable concrete can also enable rainwater in the accommodating cavity 2 to evaporate into the atmospheric environment through the permeable plate 20 with holes, so that the city is cooled and the city humidity is increased.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
