The porosity of concrete layer 2 controls between 25%-35%, and the porosity of concrete layer 2 and is planted green
The type for changing vegetation depends on the type of slope protection 1.(the chiltern when slope protection 1 is set as slope protection 1 or the roof garden of irrigation and drainage system
Soil, gravel soil property), the plant adapted to is Festuca Arundinacea, Bermuda grass, rye grass etc., and the porosity of concrete layer 2 is 25%
Left and right；When slope protection 1 is set as vertical type barricade, the plant that is adapted to is Festuca Arundinacea, Trifolium repense, Radix Ophiopogonis grass etc., and concrete
The porosity of layer 2 is 25% or so；When slope protection 1 is set as railway slope protection or highway slope protection (flinty slope), adapted to
Plant be Bermuda, Bermuda grass etc., and the porosity of concrete layer 2 is 25% or so；When slope protection 1 be set as navigable river or
When person's black-odor riverway, the plant that is adapted to is Festuca Arundinacea, Bermuda grass, yellow flag, Lythrum salicaria etc., and the porosity of concrete layer 2
30% or so.
Nutrition hole soil horizon 31 in nutrition hole 3 is uniformly mixed by Nutrition Soil and additive to be constituted, and additive
Ingredient type is adapted with the type for the afforestation vegetation planted, to meet the life of the seed in 31 surface layer of nutrition hole soil horizon
Needed for length.
As shown in Figure 1, concrete cover includes to pour when slope protection 1 is set as the ramp structures such as the side slope in river
The main body 21 on 1 outer surface of slope protection is taken shape in, main body 21 is by the incline structure of cast-in-place green concrete pouring molding, and main body
Formed by integrally casting is formed with beam structure 22 and structure of bottom girder 23, and beam structure 22 and structure of bottom girder 23 to 21 upper and lower ends respectively
Upper surface it is horizontally disposed, to constitute upper channel and lower channel, while playing the role of reinforcing 1 concrete structure of counterfort virescence.
In conjunction with shown in Fig. 1 and Fig. 3, the outer surface of main body 21 is equipped with topsoil to form topsoil layer 6, topsoil
Earth layer 6 includes that base's soil 61 and the bulky grain rubble 62(base soil 61 being layed on base's soil 61 constitute base
Soil horizon；Bulky grain rubble 62 constitutes bulky grain metalling), base's soil 61 is made of Nutrition Soil and the mixing of 1 soil of slope protection；Battalion
Feeding soil plays the role of providing Major Nutrient substance, and 1 soil of slope protection is that have preferable raw from the collection in worksite of construction ground
State adaptability, and construction operation cost can be reduced.It is piled up on topsoil layer 6 and is formed after seasonal afforestation vegetation corruption
Nutritive layer 7 is degenerated, can regrow for seed of the afforestation vegetation after dead and nutriment is provided, realize substance circular regeneration, and
So that the life cycle of 1 concrete structure of counterfort virescence extends.
Below with reference to construction method, the present invention is further elaborated (with reference to shown in Fig. 5):
S1. slope protection soil layer paving is whole, needs that construction survey personnel is sent to examine on the spot to scene, and is directed to different types of shield
The practical soil property situation of slope soil layer and slope protection soil layer formulates corresponding arrangement and method for construction, i.e., when slope protection soil is by destroying, needs
Soil remediation carried out to slope protection soil layer, then carry out the flattening readjusting operations of slope protection soil layer, so that it meets concrete cast-in-situ work
The construction requirement of industry；
S2. slope protection soil layer aperture opens up pre-manufactured hole on slope protection soil layer by the swing die of customization, and disposable completion one is flat
Pre-manufactured hole on the operation side of square rice opens up operation, and the pre-manufactured hole gradually completed in entire slope protection construction work surface is opened
It is provided as industry, while swing die vibrate and completes the tamping operation of concrete layer 2；
The cast-in-place green concrete that stirring is completed uniformly is layed in the operation side of slope protection 1 by S3. concrete layer pouring molding
On, and during pouring molding, the cast-in-place green concrete in part flows into pre-manufactured hole, that is, is completed at the same time 2 He of concrete layer
The operations for forming of concrete column 4；Then to concrete layer 2 carry out maintenance work so that 2 fast and stable of concrete layer at
Type；
S4. concrete layer aperture uniformly opens up nutrition hole 3 by swing die on concrete layer 2, and swing die includes
Pressing plate and the multiple vertical mould sticks being consistent with 3 quantity of nutrition hole being set on pressing plate, and vibration dress is connected on pressing plate
It sets, vibration device drives vertical mould stick to carry out operation of vibrating, and the nutrition hole 3 on every cubic metre of concrete layer 2 can be realized
It synchronizes and opens up operation, while being conducive to tamp pressed concrete layer 2.Complete nutrition hole 3 open up operation after, i.e., in trophopore
Nutrition hole soil is filled in hole 3, is then transplanted in nutrition hole 3 afforestation vegetation (or seed of plantation afforestation vegetation), and
In nutrition hole 3 fill nutrition hole soil while concrete layer 2 outer surface tiling hole soil (hole soil by
Nutrition Soil and soil moved in improve the original uniformly mix composition), then water to the outer surface of concrete layer 2, so that hole soil is filled in hole 5
It is interior；
S5, topsoil are laid with, and the bulky grain rubble being made of bulky grain rubble 62 is finally laid in the outer surface of concrete layer 2
Then layer is laid with the base's soil horizon being made of base's soil 61 on bulky grain metalling, it should be noted that if directly moving
Afforestation vegetation is planted, then can directly carry out laying operation；If what is planted is the seed of afforestation vegetation, need to avoid nutrition hole 3
Orifice position carry out laying operation.
Present embodiment is only explanation of the invention, is not limitation of the present invention, art technology
