Description
Technical field
The invention belongs to complex ecological field of material preparation, it is related to building waste and rice husk ash regeneration preparation water storage is saturating
The method of water material.
Background technology
With the fast development of urbanization process and urban construction, China is faced with Urban Storm Flood, urban waterlogging, haze
A series of serious ecological problems such as pollution, river pollution, shortage of water resources, depletion of groundwater, aquatic organism habitat loss.Separately
Outside, urban house and infrastructure construction scale are growing, and new construction amount, enlarging amount and engineering dismounting amount constantly increase
Add, lead to the generation of a large amount of building wastes, not only causes the waste of vast resources, also seriously affect the living environment of people.Money
Material shows the annual national generated building waste of only Old building dismounting just up to 800,000,000 tons, and generation is built in annual newly-built, dismounting
Building waste total amount is up to 15 ~ 1,700,000,000 tons, but the utilization rate of current domestic construction rubbish is extremely low.In order to solve urban waterlogging, city
The prominent sex chromosome mosaicisms such as tropical island effect, the decline of Urban Underground water level, the important measures such as country's proposition sponge urban construction, and sponge city
The construction in city needs a large amount of water permeability and water storage ability materials, and ecological permeable water storage material is prepared using building waste and agricultural wastes rice husk ash
Material is of great significance to the utilization of resources and preserving the ecological environment.
Invention content
The purpose of the present invention is to propose to a kind of preparation methods of complex ecological water permeability and water storage ability material.
The present invention mixes suitable agricultural wastes rice husk ash using building waste as primary raw material, and preparation meets sponge city
The complex ecological ring of " natural ponding, naturally osmotic, self-purification " the permeable of theory, water storage and careless plant growth that city is built
Border material is alleviated the problems such as Urban Storm Flood, urban waterlogging, haze pollute, level of ground water reduces, urban heat land effect, and is mitigated
The negative effect of building waste and crops to ecological environment.
This material is by rice husk ash base water permeability and water storage ability layer（Lower layer）With building waste base water permeability and water storage ability layer（Upper layer）It is combined.
Lower layer's water-holding capacity is stronger, and has good water penetration；The water permeability and water storage ability that upper layer has not only had also has higher strong
Degree, meets certain bearing requirements.
The present invention is achieved by the following technical solutions.
A kind of preparation method of complex ecological water permeability and water storage ability material of the present invention, includes the following steps.
（1）Using building waste discard fired brick or concrete disintegrating at 2.36 ~ 4.75mm or 4.75 ~ 9.5mm grain sizes as
Aggregate uses agricultural wastes rice husk ash as filler material.
（2）By cement:Rice husk ash:Water=1:0.5~0.95:0.95 ~ 1.35 match ratio, first by cement and rice husk ash mix
Stirring uniformly is added water, is poured into mold and is shakeout and be subject to the pressure of 0.3MPa ~ 1.2MPa and press molding, as rice husk ash
Base water permeability and water storage ability layer；By cement:Rice husk ash:Building waste:Water=1:0.1~0.4:3.0~4.0:0.9 ~ 1.2 match ratio first will
Cement, rice husk ash and building waste mix uniformly add water stirring, then mixture is poured into the molded good permeable storage of rice husk ash base
In the mold of water layer, shakeouts and the pressure for being subject to 0.5MPa ~ 1.5MPa presses molding, as building waste base water permeability and water storage ability layer.
（3）It conserves under ambient temperature and moisture and demoulds for 24 hours, grass seeds is uniformly dispensed on upper layer of material surface, then cover about 1mm thickness
Soil, and daily watering maintenance 28d at normal temperatures.
The interior sky of mold of the present invention may be sized to long × wide 1000mm ~ 1200mm × 600mm ~ 800mm, high
Spend 500mm ~ 800mm（Subsurface material 300mm ~ 500mm, upper layer of material 200mm ~ 500mm can be accommodated）, can also be wanted according to design
It asks and flexibly determines mold size.
The present invention is using building waste, rice husk ash as primary raw material, using cement-based material as cementitious matter, is conserved and is made by room temperature
Standby complex ecological water permeability and water storage ability material, can be used for sponge urban construction, mitigates municipal drainage and pressure of flood, can alleviate Urban Thermal
Island effect keeps soil moisture, improves the life condition of urban ground vegetation and edaphon, and alleviates to a certain extent
Resource pressure improves resource utilization.
