Detailed description of the invention

As shown in Figure 1-Figure 3, the drainage type water-permeable brick 10 of first-selected embodiment of the present utility model includes top 1, middle part 2, bottom 3.

Top 1 has a thickness H1, and its end face 11 is the brick face of water-permeable brick 10.

Middle part 2, between top 1 and bottom 3, connects top 1 and bottom 3, and has a thickness H2.

Bottom 3 has a thickness H3, and its bottom surface is the bottom surface of water-permeable brick 10.

Preferably, the width W3 of bottom 3 is narrower than the width W1 on top 1 so that after water-permeable brick 10 lays, as it is shown on figure 3, form the first tank 32 between the side of the bottom 3 of adjacent two pieces of water-permeable bricks. First tank 32 has a width W4.

Preferably, middle part 2 comprises two recessed sides, forms groove 21. The lower edges of groove 21 is connected with the end face of the bottom surface on top 1, bottom 2 respectively so that after water-permeable brick 10 lays, as it is shown on figure 3, be formed over broader second tank 22 of ratio the first tank 32 at the first tank 32. Second tank has a width W5.

Preferably, the thickness H1 on top 1 is 3-10 centimetre, and the thickness H2 at middle part is 3-10 centimetre, and the thickness 2-8 of bottom is centimetre.

Preferably, groove 21 is the cambered surface groove of the horizontal expansion along water-permeable brick 10. Preferably, as it is shown in figure 1, this cambered surface is semicircle cambered surface, the lower edges of semicircle cambered surface is tangent with the end face of the bottom surface on top 1, bottom 3 respectively, thus ensureing the weight capacity of brick body entirety and the stable and firm of partial structurtes to the full extent.

Preferably, the width W4 of the first tank 32 is 3-12 centimetre.

Preferably, in order to permeable better, water-permeable brick 10 is made up as main raw material of the quartz sand that size shape is identical.

By such design, during the rainy day, ground water penetrates down into the brick body of water-permeable brick, outwards ooze out brick body still further below, quickly being discharged in the first tank 32, the water on brick face is such that it is able to continue to penetrate in brick body so that brick body gives full play to the effect of drainage medium.

When rainfall is bigger time, if the water in the first tank 32 cannot be drained in time, the second tank 22 may be provided for the bigger water capacity and receives space, improves the drainage effect of water-permeable brick 10 further.

If water-permeable brick of the present utility model lays the situation occurring loosening after using a period of time, due to the existence of brick face lower flume, after pedestrian steps on, hydrops only can flow in the sink, without there is situation about being extruded under brick face.
