Abstract

The utility model discloses a greened concrete component with grass growing which belongs to the means used for the earth, the wood and the hydraulic engineering building. The greened concrete component with grass growing is integratively poured by inner and outer concrete with different properties. The basic configuration is a regular hexagon, a rectangle and a square. The cross section of the outer frame of the means is an approximately trapezoidal pentagon with narrow upper part and wide lower part. The inclined face is higher than the inner layer and forms a concave face. The concave face is filled with the soil which can be cultivated. The greened concrete component with grass growing has high germination rate and is not easy to break and can simultaneously reduce the heat absorbing capacity and stop the nutrient element from escaping.

Description

A kind of green concrete member that grows grass

Technical field

The utility model relates to soil, wood, water conservancy construction member class, particularly a kind of green concrete member that grows grass, refer to especially a kind of integrated by inside and outside two kinds of concrete of different nature, the green concrete member of moulding by casting simultaneously.

Background technology

As everyone knows, along with rapid development of economy, progress of science and technology, the human new concept of harmonious co-existence between man and nature of establishing gradually, all kinds of water conservancy project buildings begin to change under the prerequisite that guarantees existing function by based on functional, make rational use of resources, allow engineering construction and ecological environment coordinate, create the environment that is more suitable for human survival by engineering construction; For hydraulic engineering, changing development and use into by single able to resisting flood and drought combines with environmental protection, make it more to coordinate with the existence of human society, the high development of economic society, realize sustainable utilization of water resources, the research and the application of environmental engineering material, having become the new research and development direction of water conservancy and other geotechnical engineering building materials, also is the basic important means that realizes harmonious co-existence between man and nature; Engineerings such as river dyke adopt hard building stones, concrete etc. to do protective materials usually, when consolidating and having strengthened the border, land and water, also natural environment have been caused destruction.There is a kind of common green concrete to protect piece in recent years; recover to provide effective way for solving security protection and environment; as shown in Figure 1; this common green concrete protects piece; obtained widely applying, it is to adopt the outer double mould of doing of bearer bar of prefabricated C20 concrete on every side, and non-fine concrete is filled in the centre; fill nutrition soil and plant grass in non-fine concrete, the common green concrete of this kind protects piece and has following shortcoming:

But 1 cultivated area is little, germination percentage is low, outer bearer bar can not be planted grass, therefore can plant the grass part in the middle of and only account for 65% of member area, in this area of 65%, because of the surface porosity factor of non-fine concrete is 30%, the area that then can germinate is 0.65 * 0.3=0.195 only, be 19.5%, so germination is bad;

2, because inside and outside two kinds of concrete are not the while integrated moldings, segregation phenomenon appears easily;

3, the same plane of bearer bar and non-fine concrete place can't retain surface soil, and the concrete surface that can grow grass directly is exposed under the sunlight, absorbs heat in a large number, and withered easily after grass is germinateed, the dried-up phenomenon of hot dormancy appears in growth back easily;

4, after the fertilizer of filling decomposes in the concrete pore,, overflow easily and lost efficacy owing to do not intercepted.

In sum, common green concrete protects that piece is anxious to be waited to be improved.

The utility model content

The purpose of this utility model is to provide a kind of green concrete member that grows grass, the prior art cultivated area is little, germination percentage is low but solved, occur segregation phenomenon easily, and surface soil can't retain, the fertilizer of the filling shortcomings such as inefficacy of overflowing easily in the concrete pore.

Structure of the present utility model is by the integrated while moulding by casting of inside and outside two kinds of concrete of different nature, has avoided because of the not good bond strength that causes of the mixed soil connection of the old and new is low segregative disadvantage; The profile of member is regular hexagon, rectangle, square substantially, also can determine shape according to requirement of engineering; Member housing layer cross section is up-narrow and down-wide, and the pentagon of approximate trapezoid, inclined-plane exceed internal layer and form the surface for concave panel, can change the shortcoming that area is little, germination percentage is low of can growing, but makes sown area be increased to 85% by original 65%, has improved germination percentage greatly; Member housing layer adopts general one-level to join concrete, and compressive strength is C20, and is middle for having the non-fine concrete of effective aperture; During enforcement, in having the non-fine concrete hole of effective aperture with air-blowing, vibration mode filling compound nutritional material, but and in the member concave surface, cover mold to flushing with the outer, be convenient to plant germination, reduce the influence of high heat to germinateing of generation at sunshine, changed the original bad shortcoming of plant germination and growth environment.

Advantage of the present utility model is:

1,, makes and low, the peripheral compressive strength height of construction breakage rate and not easily separated owing to the moulding of member integrated casting;

2, because member housing layer cross section is up-narrow and down-wide formation concave surface, the germination area is increased, improved germination percentage and green percentage; But can make to hold mold and strengthen and to adhere to stability, can reduce amount of heat absorption simultaneously, intercept the effusion of nutrient.

The specific embodiment:

As shown in Figures 3 to 5,1 is that housing layer, 2 is that non-fine concrete internal layer, 3 is concave surface, 4 is plant, the utility model is by inside and outside two kinds of concrete while moulding by casting of different nature, increase bond strength, not easily separated, profile is regular hexagon, rectangle, square substantially, also can determine shape according to requirement of engineering; Member housing layer cross section is up-narrow and down-wide, and the pentagon of approximate trapezoid, inclined-plane exceed internal layer and form the surface for concave panel 3, has changed the member shortcoming that area is little, germination percentage is low of can growing; Housing layer 1 adopts general one-level to join concrete, compressive strength is C20, internal layer is the non-fine concrete with effective aperture, compressive strength is 5.00Mpa, porosity is greater than 30%, water/binder ratio is 0.34, during enforcement, in non-fine concrete 2 holes with effective aperture with air-blowing, vibration mode filling compound nutritional material, but contain mold 1 in the concave surface, effectively reduce the influence of high heat to germinateing of generation at sunshine, changed the original bad shortcoming of plant germination and growth environment, effectively intercepted the fertilizer effusion.

During enforcement, in non-fine concrete 2 holes with effective aperture with air-blowing, vibration mode filling compound nutritional material, but and in member concave surface 3, cover mold to flushing with the outer, be convenient to plant germination, reduce the influence of high heat to germinateing of generation at sunshine, further changed the original bad shortcoming of plant germination and growth environment.

As shown in Figure 6,, form the external form of neat appearance, not only play protective action, also beautify the environment simultaneously, keep ecological balance for the utility model is laid on enforcement figure on river, the river levee dam.
