Description
Technical field
The present invention relates to ecological, environmental protective technical field, the method for specifically a kind of eco-concrete improvement falling zone.
Background technology
After Three Gorges Reservoir is built up, water level, which disappears, rises that opposite with the natural rhythm and pace of moving things and the duration is long, and reservoir area two sides generate large area
Falling zone, bio-diversity reduce, and ecological functions are degenerated.In recent years, Three Gorges Reservoir water pollution, soil regime is increasingly
Deteriorate, Eco-Environment Frangibility aggravation, as the zone of transition between reservoir water body and land, falling zone not only influences reservoir stability
Stability causes the serious destruction of Three Gorges scenic spot natural character, while also to the ecological safety of surrounding cities and sustainable development
Cause great threat.
The existing method for administering falling zone is mostly only to offset to fall band and repaired from structure or plant angle.But only from
Structural point administers falling zone, causes greatly to destroy to the natural land of reservoir area of Three Gorges；Falling zone only is administered from plant angle, by
In slopes by souring repeatedly, it is difficult to realize lasting falling zone restoration of the ecosystem.There is an urgent need to take plant measures and
The mode comprehensive treatment that engineering measure is combined carries out two river falling zone ecological barrier constructions, prevents erosion, prevent and subtract
Lack geological disaster, keep the stability of main city Riparian Zone, increase species diversity, improves Binjiang ecological environment.
Invention content
The object of the present invention is to provide a kind of methods that eco-concrete administers falling zone, which is characterized in that including following
Step：
1) when water level is minimum, the falling zone slope surface that meets water is cleared up, flattened and is tamped；
2) eco-concrete is configured；The eco-concrete composition and weight proportion are：
The preparation method of the eco-concrete is as follows：
2-1) prepare aggregate (rubble and float stone)；
2-2) Hou Jiashui is stirred evenly in aggregate, stir water and aggregate 2~3 minutes, stirring to particles of aggregates surface wettability
?；
2-3) ready cement, iron tailings sand and flyash are poured on aggregate, carry out aggregate stirring, mixing time 5
~8 minutes, ensure that aggregate is wrapped by cement；
2-4) remaining water and water-reducing agent are poured into aggregate and cement and stirred, when aggregate is wrapped completely by cement cementitious material
After wrapping up in, surface is simultaneously general glossy, you can pours eco-concrete；
3) eco-concrete of thickness 6-10cm is poured on the falling zone surface of compacting；
3) eco-concrete covers Composite nutrient soil, and sow after certain curing time on eco-concrete
Grass-seed or planting plants.
4) before promoting water level, the plant that the grass-seed of sowing has all emerged or planted has been sent from new root.
Further, the pH value of the eco-concrete is 6.8~7.4.
Further, in the eco-concrete,
Rubble：Grain size is 4.75mm~9.50mm, apparent density 2500kg/m3, bulk density 1350kg/m3。
Float stone：Grain size is 4.75mm~9.5mm, apparent density 1700kg/m3, bulk density 850kg/m3, water absorption rate is
10.5%.
Flyash：Density is 2200kg/m3。
Cement：P.O42.5 grades of portland cements, density 3000kg/m3。
Iron tailings sand：Grain size is 0.075mm~0.16mm, apparent density 3005kg/m3, bulk density 1745kg/m3。
Water-reducing agent：Polycarboxylic acid series high efficiency water reducing agent, water-reducing rate reference data are 25%, density 1100kg/m3。
Further, the concrete curing time is 3~10 days.
Further, the Composite nutrient soil is by fertile land and decomposed dung mixed preparing.
Further, the grass-seed be Buffalo bur, sainfoin, coronilia varia and silphium perfoliatum L in one kind or
Person is several.Selected grass-seed should be wide adaptability, and cold-resistant high temperature resistant, resistance to water logging, resistant to diseases and insects are strong, saline-alkali tolerant, Gu soil is aqueous
The kind that ability is strong and survival rate is high.
Further, the plant is Nanchuan willow, mulberry tree, paspalum notatum, R. soongorica, Nitraria sibirica, camel hoof valve, sand
One or several kinds in wormwood artemisia, faenum graecum.Selected plant should be wide adaptability, cold-resistant and high temperature resistant, resistance to water logging, resistant to diseases and insects
By force, saline-alkali tolerant, Gu the soil kind that water holding capacity is strong and survival rate is high.
Further, the plant seeding or implantation time will be at least 35 days apart from the wet season.
The present invention can solve the defect that existing falling zone control measures are difficult to realize lasting restoration of the ecosystem, technology
Effect is unquestionable：
A. the physical and chemical performance of eco-concrete is increased dramatically.The eco-concrete has light weight, and intensity is big, thoroughly
Water, good permeability, be conducive to plant growth the advantages that, overcome the shortcomings that conventional concrete basicity height is unfavorable for plant growth, it is good
Good permeable, permeability ensures vegetation root system effective development in the gap of concrete.
B. the perfect adaptation of falling zone improvement and landscape planting is realized.A kind of eco-concrete proposed by the present invention is administered
The method of falling zone solves the defect that existing falling zone control measures are difficult to realize lasting restoration of the ecosystem, both ensure that and disappeared
The stability of band is fallen, and realizes the purpose of landscape planting.
Specific implementation mode
With reference to embodiment, the invention will be further described, but should not be construed the above-mentioned subject area of the present invention only
It is limited to following embodiments.Without departing from the idea case in the present invention described above, according to ordinary skill knowledge and used
With means, various replacements and change are made, should all include within the scope of the present invention.
Present embodiment discloses a kind of methods that eco-concrete administers falling zone, include the following steps：
1) when water level is minimum, the falling zone slope surface that meets water is cleared up, flattened and is tamped；
2) eco-concrete of thickness 8cm is poured on the falling zone surface of compacting, constituent is according to mass percent
For rubble：Float stone：Water：Flyash：Cement：Iron tailings sand：Water-reducing agent=1.000：0.600：0.480：0.200：0.100：
