Description

A kind of three-dimension vegetative net composite permeable concrete revetment grass-planting brick

Technical field

The utility model relates to the protection of natural resources and environment technical field, particularly a kind of three-dimension vegetative net composite permeable concrete revetment grass-planting brick.

Background technology

In annual rainy season, a large amount of rainwater easily pours water body with the silt of embankment, and a large amount of losses of silt can cause channel aggradation, cause river course flood, and the reduction of discharge capacity also can affect Water quality, so the structure of bank protection is very important.

Traditional bank adopts concrete products mostly, and the cold dull gray of this material is heavy, lacks gas permeability and water permeability, and rough surface and be strong basicity often causes the destruction of river ecological environment.Green grass-planting brick occurs in recent years, provide certain approach for solving security protection and environment harmony.

But in recent years use practice shows, after side slope is laid grass-planting brick in one period, owing to lack binding between the member, meets with rain drop erosion, tends to produce the slippage breakage.Simultaneously, also there is following shortcoming in current grass-planting brick:

1) afforestation effect is not ideal, and the lawn coverage scale only reaches 30%;

2) be only applicable to the more area of rainwater, when rainwater was not enough, surperficial grass planting thirst easily;

3) grass-planting brick hole bore is larger, washed away by stormy waves, and Nutrition Soil is washed away, and the hole bore is less, and the plant plant is carefully few, can not form ecological effect.

Cause the less-than-ideal main cause of afforestation effect to be: these grass-planting bricks adopt pervious concrete usually.Pervious concrete utilizes concrete without the fines principle, take cement as main cementitious materials, the proportioning efficient additive (have foaming, diminishing, early strong, regulate the functions such as pH value and Promoting plant growth), has the above concrete strength of C25, the hole that 15%-20% is arranged in the structure, have better water permeability, be beneficial to plant root growth.But because the top layer do not have firm soil layer, plant is difficult to short-term and adheres on pervious concrete and take root.

Summary of the invention

The purpose of this utility model is the above-mentioned deficiency for prior art, and the three-dimension vegetative net of first plant being grown easily is applied to the pervious concrete surface, forms the high slope protecting grass planting bricks of a kind of vegetation coverage.

For achieving the above object, the technical scheme that the utility model proposes is: a kind of three-dimension vegetative net composite permeable concrete revetment grass-planting brick, it is characterized in that: comprise brick body and three-dimension vegetative net, be provided with anchor hole around the described brick body, described three-dimension vegetative net adheres on the brick body.

Further, described brick body is middle high, low all around, and is the Wave-shaped structural perpendicular to water (flow) direction.

Further, described brick body is the pervious concrete brick.

Further, described anchor hole aperture is
