Problems solved by technology

But on the one hand, the soil itself will be polluted during the process of purifying rainwater, and the collection and purification of polluted soil will cost a lot.
On the other hand, rainwater cannot be efficiently collected and used
[0011] 3. Most of the current public roads are paved with impermeable pavement, and the initial sump has no purification ability, and the first 2mm-5mm of the initial rainwater is generally seriously polluted, the flow rate is relatively small, and the acidity is relatively high
[0012] 4. The method of adding artificial pools to regulate and store rainwater cannot save land and occupy road space
[0013] 5. Centralized water storage requires high requirements for the drainage system, and it is easy to cause road accumulation during heavy rain

Embodiment 1

[0072] A method for preparing a water-permeable material. In terms of volume fraction, 40% of sand with a particle size of 6-18mm, 20% of P.P42.5 cement, and 20% of activated carbon are evenly stirred, and then 0.2% of chlorinated Calcium and 19.8% water are fully mixed and stirred; after the permeable material module of the required size and shape is prepared, it is demoulded, dried in the sun, and maintained for molding.

Embodiment 2

[0074] A method for preparing a water-permeable material. In terms of volume fraction, 60% of pulverized coal slag with a particle size of 6-18mm, 15% of asphalt, and 10% of straw are evenly stirred, and then 0.8% of sodium sulfate and 14.2% of water are added , fully mixed and stirred; after the permeable material module is prepared into the required size and shape, it is demoulded, dried in the sun, and maintained for molding.

Embodiment 3

[0076] A method for preparing a water-permeable material. In terms of volume fraction, 45% of bricks with a particle size of 6-18mm, 18% of epoxy resin, and 18% of polyvinyl alcohol fibers are evenly stirred, and then 0.4% of calcium nitrate is added and 18.6% water, fully mixed and stirred; after preparing a permeable material module of the required size and shape, it was demoulded, dried in the sun, and maintained for molding.

Abstract

The invention provides a pervious material as well as a preparation method and an application thereof. The pervious material is mainly prepared from a coarse aggregate, an adhesive material, a water purification functional material, and water. As being influenced by a natural shape of the coarse aggregate, the interior of the pervious material is provided with multiple gaps with a high porosity, the gaps can allow a water body to pass through, and the water body can be filtered by virtue of the water purification functional material. The pervious material provided by the invention has high compression strength and breaking strength, has functions of storage regulating permeation and storage regulating purification at the same time, and can be used for constructing various underground spaces for purifying and storing dispersed rainwater by virtue of a simple way of building blocks. The preparation method of the pervious material provided by the invention is simple in process and low in cost, and is suitable for large-scale production. The pervious material provided by the invention has the functions of storage regulating permeation and storage regulating purification at the same time, can be used for constructing various underground water purification devices and underground reservoirs, and can also be used for constructing debris flow protection slopes.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a water-permeable material and its preparation method and application. Background technique [0002] As a non-traditional water source, rainwater was once used as a disaster prevention and control. Now rainwater has become an important available water resource and one of the important water sources to alleviate the tension of water resources. Rainwater utilization is a kind of resource development and conservation. It is of great significance to improve the ecological environment of the whole city. [0003] a) Collecting and utilizing rainwater can directly save water resources and relieve urban water supply tension. [0004] b) Build infiltration facilities to infiltrate rainwater and conserve groundwater. [0005] c) Reduce the rain and flood load in urban areas, and reduce the flood peak flow and flood threat downstream of the receiving water body. [0006] d) I...
