P. A rainwater
collection device
based on concrete
sand-based porous
bricks
(ZL201310237771.8)
CN103352411
(A)—2013-10-16
The invention relates to a rainwater penetration collection device based on concrete-sand-based
water-permeable bricks. The invention belongs to the field of construction design. The invention is
characterized in that: pedestrian walkways and squares are paved by using concrete-sand-based
water-permeable bricks; rainwater enters the concrete-sand-based pavement water-permeable bricks and
cover-plate water-permeable bricks, and is filtered by a gravel bedding layer and a crushed stone
bedding layer; rainwater enters a rainwater collection ditch through the water-permeable bricks of a
ditch wall of a rainwater-collection thin ditch side wall; the rainwater is then gathered to a water storage
tank on the square and is used as a landscape or used for irrigation. The device is characterized in that
screened and processed desert sand is used as a main aggregate; high-grade cement is adopted as an
adhesive; and proper additives are added. Frustum-shaped water-permeation holes are provided on brick
bodies, and anti-slip stripes are arranged on the brick body. The device provided by the invention has the
advantages that: desert sand is sufficiently utilized; the strength is high, and cost is low; the water
permeability is good, and the water-permeation holes are prevented from blockage; the device is safe
and comfortable; a good rainwater collection plane which is the square is sufficiently utilized; and
rainwater processing is simple and feasible
