Embodiment 1

[0025] Taking the reconstruction of the fountain square of Dalian University of Technology as the design background, a rectangular outer outline with a side length of 100m*300m is adopted. A circular reservoir is located in the center of the square, with a diameter of 10m and a depth of 2m; It is a pedestrian walkway with a width of 3m; 12 rain-collecting rills are evenly distributed in the square according to the angle. cm plain concrete cushion, directly add concrete sand-based cover plate on the ditch wall; lay coarse sand leveling layer, geotextile and gravel cushion with a particle size of 10mm in sequence under the permeable bricks of the square pavement; lay next to the ditch wall Geotextiles and gravel cushions with a particle size of 15mm.

[0026]The outer contour size of the square pavement permeable brick is 20cm long, 10cm wide, and 6cm high; the brick body is arranged with 2 permeable holes, and the permeable holes are designed in a circular frustum shape, with a...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of architectural design, and relates to the design of a rainwater permeation collection device based on sand-based permeable bricks, in particular to the design and manufacture of a concrete sand-based permeable brick, which is used to collect and filter rainwater from roads and squares rainwater. Background technique [0002] According to the data released by the National Development and Reform Commission and the Ministry of Water Resources, more than 400 cities in China are short of water, accounting for about 2 / 3 of the cities in the country, and about 200 of them are seriously short of water. In particular, 30 of the 32 large cities with a population of more than 1 million are short of water. With the continuous expansion of the city scale, the rapid increase of the urban population and the rapid development of the economy, the water demand continues to increase, and a large amount of sewage is produced...
