Water purifying type greening brick applied to ecologic slope protection and preparation method thereof

Abstract

The invention discloses a water purifying type greening brick applied to ecologic slope protection. The greening brick comprises a soil wrapping hollow building block, a composite drainage net and a water permeable porous building block which are sequentially arranged from top to bottom; the soil wrapping hollow building block is prepared from dredged spoil, zeolite, coal ash, portland cement, water glass, lignosulfonate and water; the water permeable porous building block is prepared from ceramic particles, clay, an admixture, portland cement, a pore forming agent, hydroxypropyl methyl cellulose and water. The invention further discloses a preparation method of the water purifying type greening brick. The soil wrapping hollow building block is light and high in structure stability, the water permeable porous building block is good in water permeability and high in porosity, according to the water purifying type greening brick, by combining the soil wrapping hollow building block, thecomposite drainage net and the water permeable porous building block, effective ecologic slope protection can be achieved, and rainwater can be absorbed, filtered, purified, drained and protected.

Description

technical field [0001] The invention belongs to the technical field of ecological corridors, and in particular relates to a water-purifying green brick applied to ecological slope protection and a preparation method thereof. Background technique [0002] At present, correctly handling the relationship between project development and environmental protection has become an important topic for people to study sustainable economic development, and it is also a problem that must be faced and taken seriously in the rational use of resources, environmental protection, and beautification of the environment in engineering construction. The construction of highways and water conservancy projects is closely related to the natural environment, and improper handling may lead to a series of ecological environment and engineering problems such as plant damage, soil erosion, landslides, and slope instability. [0003] Ecological slope protection technology refers to using the relatively dev...

AI Technical Summary

Problems solved by technology

At present, the problems of ecological slope protection are: poor landscape effect, single slope protection mode cuts off the connection between road and nature, long construction cost and construction period, and is not suitable for maintenance; limited ecological function, lack of ecological measures such as ecological corridors, not suitable Conducive to the survival and reproduction of plants and microorganisms
