Embodiment 1

[0027] Such as Figure 1-4 As shown, the permeable brick structure of the present invention includes: a silica sand permeable layer 1 composed of aggregate particles and a hydrophilic binder covering aggregate, and a silica sand permeable layer 1 composed of aggregate particles and a binder covering aggregate The sand-free concrete water-permeable layer 2, and the water-guiding channels 5 (three are shown in the figure, but other numbers may also be possible) are provided through the concrete bottom layer 4 .

[0028] Wherein, the sand-free concrete permeable layer 2 is located below the silica sand permeable surface layer 1 and combined with the silica sand permeable surface layer 1 . Preferably, the thickness of the silica sand water-permeable layer 1 is 1.5-3 cm, and the thickness of the sand-free concrete water-permeable layer 2 is 4-6 cm. Wherein, the aggregate particle size contained in the silica sand water-permeable layer 1 is relatively small, and the particle size i...

Embodiment 2

[0045] Figure 5 Shown is the permeable brick of Embodiment 2 of the present invention, which is basically the same as Embodiment 1, except that the structure of the main body 41 and the blocking portion 42 of the concrete bottom layer 4, specifically, the main body 41 and the blocking portion 42 is an arc-shaped connection structure, the inner surface of the blocking portion 42 is an inclined structure, and the connection between the inner surface and the upper end of the blocking portion 42 is also a circular arc transition. Wherein, preferably, the radius of curvature of the arc-shaped connecting portion is 10-20 mm, the inclination of the inclined structure is 5-10 degrees, and the radius of curvature of the arc transition is 5-10 mm.

[0046] With such a structure, when the rainwater flows through the blocking portion 42, it is smoother, and the effect of scouring sand and soil is better.

Embodiment 3

[0048] Figure 6-7 , shows the permeable brick of Example 3, wherein, the bottom surface of the sandless concrete permeable layer 2 is provided with an impermeable water-retaining layer 21, and the water-retaining layer 21 is arranged on the side of the outlet end, and is in the form of The slope is arranged so that rainwater can flow from the right to the left in the figure. More preferably, at least part of the gap exists between the water-retaining layer 21 and the sand-free concrete water-permeable layer 2 to facilitate the circulation of rainwater.

[0049] With such a structure, rainwater can be concentrated toward the side of the inlet 6, so that the water collected on the inlet side is more concentrated, and the scouring force generated to the right is more obvious.

[0050] In another preferred solution, the water-retaining layer 21 is a wave-shaped structure (such as roof tiles), and gaps are formed at some positions at the top of the wave, so that rainwater can dir...

Abstract

The invention relates to a dustproof self-cleaning combined self-draining water permeable brick. The dustproof self-cleaning combined self-draining water permeable brick is characterized by comprisinga first permeable layer, a second permeable layer and a lower inclined water diversion channel, wherein the first permeable layer has first water permeable pores; the second permeable layer has second water permeable pores. The dustproof self-cleaning combined self-draining water permeable brick is characterized in that the pore diameter of the second water permeable pores is greater than that ofthe first water permeable pores; the channel can drain and has certain capability of storing rainwater. The dustproof self-cleaning combined self-draining water permeable brick is provided with the inclined water diversion channel, so that the infiltration speed of the rainwater is effectively increased, and the adjusting capability for the water volume of the rainwater is high; in addition, a water diversion pipe in the bottom layer of the water permeable brick is obliquely arranged to realize a water storage effect; in addition, the blockage of the water permeable brick can be avoided; in addition, the dustproof self-cleaning combined self-draining water permeable brick can relieve the pressure of air drying, is not easy to dust and can reduce the haze phenomenon.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a dust-proof self-cleaning combined self-draining permeable brick. Background technique [0002] At present, the floors of city squares, commercial streets, sidewalks, community activity sites, parking lots, etc. are mainly paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The impermeable floors are very harmful to the urban environment. When it rains, the impermeable ground completely prevents the rainwater from infiltrating directly into the ground, and the accumulated water makes it very inconvenient for people to travel; the precious water resources finally flow away with the water guide channels, which increases the burden on urban drainage facilities The large loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health of urban vegetation, makes it difficult for the surface pl...
