As present invention further optimization technical solution, in the step S3, the hole diameter of punching is 25 ㎜, depth
For 60 ㎜.
As present invention further optimization technical solution, in the step S4, on the Nutrition Soil and planting soil of laying also
Film can be covered to be conserved or sprinkling maintenance.
Environmentally friendly ecological afforestation concrete of the invention and its construction method can by using above-mentioned technical proposal
With reach it is following the utility model has the advantages that
1) the waste residue solid waste after mining, ore dressing can be recycled, alleviates environmental pollution, turns waste into wealth；
2) eco-concrete for selecting waste residue solid waste to recycle, reduces construction cost；
3) small particle stone and mountain flour, the waste residue after taking full advantage of discarded mining, ore dressing, obtained ecology are used
The not only intensity of concrete is higher, and anti-filter effect is good, eliminates bottom and is laid with geotextiles, simplifies working procedure, further
Save production cost.
Specific embodiment
The present invention will be described further with specific embodiment below.In preferred embodiment it is cited as "upper",
The terms such as "lower", "left", "right", " centre " and " one ", only being illustrated convenient for narration, rather than it is implementable to limit the present invention
Range, relativeness is altered or modified, under the content of no substantial changes in technology, when being also considered as the enforceable model of the present invention
Farmland.
Environmentally friendly ecological afforestation concrete of the invention, is mixed: stone by following components in parts by weight
1500 parts, 300 parts of cement, 60 parts of water and additive, the additive include the polycarboxylic-acid for accounting for cement weight 0.5-1%
Water-reducing agent, 0.4 part and 2 parts of early strength agent of water-retaining agent.
In specific implementation, the stone is the barren rock disintegrating slag after mining or ore dressing, and the diameter range of the stone is 5-

The present invention also provides a kind of construction method of environmentally friendly ecological afforestation concrete, this method includes following step
It is rapid:
Step S1, environmentally friendly ecological afforestation concrete described in any of the above-described embodiment is stirred；
In specific implementation, in the step S1, the material is that stone, cement, water and additive specifically include:
The stirring that material is carried out using JGZR350 self-falling mixer, stirs the loading sequence of material are as follows: stone → cement → outer
Add agent；
During site operation, by technical operation personnel according to situations such as different soil properties, weather, temperature make it is appropriate adjustment with
Mixing time is controlled, so that every stone has cement slurry package.
In addition, when being opened mix with blender every time, it should be noted that monitoring opens with detection and mixes the first two initial, three tank concrete
The workability of mixture should analyze immediately situation and handle when such as undesirable, until the workability of mixture conforms to
It asks, it can continuous production.By being sufficiently stirred, the various composition materials of ecological concrete should be made to be uniformly mixed, color one
It causes.
Step S2, the cast-in-place environmentally friendly ecological afforestation concrete being stirred is vibrated into region to be laid, and in time
Type；
In step S2, the region to be laid is that the requirement of engineering such as road, water conservancy are administered and the side slope of greening, and vibrate at
The environmentally friendly ecological afforestation concrete surface of type need to be without laitance, and bottom is without heavy slurry.
Before carrying out environmentally friendly ecological afforestation concreting, the carry out sloping surface arrangement to construction area is also needed,
It specifically includes:
According to design slope ratio, carry out cutting slope and finishing slope surface；
According to design height, width and depth, and in digging process, frequent checking measurements is needed to excavate plan-position, horizontal mark
Whether high, control pile No., grade of side slope etc. meet construction drawing requirement；
It applies for checking and examination in time after slope surface trimming, carries out next procedure construction in time, prevent the side slope exposure duration rebuild too long, slope surface
It is destroyed by artificial or rainwater.
Step S3, it is uniformly punched in the region surface to be laid for being equipped with environmentally friendly ecological afforestation concrete, makes hole
Gap rate is 25%-35%, and compression strength is not less than 8N/ mm 2, antiscour flow velocity is not less than 7m/s；
In specific implementation, in the step S3, the hole diameter of punching is 25 ㎜, and depth is 60 ㎜.
Step S4, Nutrition Soil and planting soil are laid in the environmentally friendly ecological afforestation concrete surface for pouring completion.
In specific implementation, in the step S4, refer in the environmentally friendly ecological afforestation concrete for pouring completion by step
What the surface that rapid S3 is obtained had been punched is equipped with ecological afforestation mixed mud.Preferably, may be used also on the Nutrition Soil and planting soil of laying
Covering film is conserved or sprinkling maintenance.
Environmentally friendly ecological afforestation concrete of the invention can be applied to the slope treatment of the engineerings such as road, water conservancy and green
Change, needs to repave the planting soil of 4 ㎝ thickness after watering according to local climatic condition before kind of grass, keep water-retaining agent, Nutrition Soil abundant
It penetrates into green concrete hole, the growth of more advantageous grass planting, afforestation coverage rate is up to 90% or more.
Although specific embodiments of the present invention have been described above, those skilled in the art should be appreciated that this
It is merely illustrative of, various changes or modifications can be made to present embodiment, without departing from the principle and substance of the present invention,
