Massaging water-passing water-permeable grass-planted brick with heavy-metal filtering layer and preparation method thereof

Abstract

The invention discloses a massaging water-passing water-permeable grass-planted brick with a heavy-metal filtering layer and a preparation method thereof. The massaging water-passing water-permeable grass-planted brick with a heavy-metal filtering layer comprises a water-permeable body, a water-passing gallery located at the lower part of the water-permeable body, a soil-filled body located at the upper part of the water-permeable body, a massaging body arranged on the upper surface of the water-permeable body and a filtering layer located in the soil-filled body, wherein the water-permeable body is composed of recycled aggregate of concrete, cement, fly ash, water and a water reducer. The preparation method provided by the invention is simple in process and uses cheap raw materials; the grass-planted brick prepared by using the method can reach a designed level, and the structure of the brick can overcome the problem that a local underground reservoir is formed due to afflux of rainwater into underground water; meanwhile, due to planting of plants and arrangement of the heavy-metal filtering layer, the brick can effectively remove heavy metals, the turbidity of water and air so as to achieve the purposes of purifying air and beautifying environment.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a massage-type water-permeable grass-planting brick with a heavy metal filter layer and a manufacturing method thereof. Background technique [0002] Heavy metals refer to metals with a density greater than 4.5 g per cubic centimeter, usually including mercury (mercury), cadmium, lead, chromium, arsenic, etc.; heavy metals are usually not biodegradable, on the contrary they can be biomagnified by the food chain, and become thousands of It is enriched in plants and finally enters the human body through the food chain. When heavy metals enter the human body, they can interact strongly with proteins and enzymes, making them inactive, and may accumulate in large quantities in certain organs of the human body, causing headaches, dizziness, chronic poisoning, and even death; The Ecological Environmental Protection Plan pointed out that key areas for heavy meta...

Problems solved by technology

When heavy metals enter the human body, they can interact strongly with proteins and enzymes, making them inactive, and may accumulate in large quantities in certain organs of the human body, causing headaches, dizziness, chronic poisoning, and even death; The Ecological Environmental Protection Plan pointed out that key areas for heavy metal pollution prevention and control need to formulate and implement comprehensive heavy metal pollution prevention and control plans to effectively prevent and control environmental risks and improve regional environmental quality. Comprehensive rectification of outstanding problems in river basins and regions, and establishment of a comprehensive prevention and control coordination mechanism for the "Manganese Triangle" (the three counties of Xiushan County in Chongqing City, Huayuan County in Hunan Province, and Songtao County in Guizhou Province that have serious environmental pollution problems in the mining and production of manganese ore) Therefore, it is very necessary to develop heavy metal removal technology; in addition, the increase of waste concrete also has a negative impact on the environment, increasing atmospheric dust and environmental load
