Description
Technical field
The utility model relates to a kind of rainwater and keeps and the green roof of air cleaning module facility, is specifically related to a kind of ecology utilization and air cleaning system based on rain water on roof and forms ecologic building thing of new generation.
Background technology
From earlier 1900s, Global Urbanization level rose violently 50% of the end of the century from 15% of the beginning of the century, and it is " century in city " that 21 century is more described as.A key character of urbanization is exactly waterproof ground, roofing area change.Not moisture roof building thing has replaced good forest land, the farmland of water permeability, cause city overland runoff amount to increase, concentration time shortens, the reduction of basin backwater ability, the speed of confluxing is accelerated, and the ability of basin original smoothization flood waveform reduces, and comes to a point before making flood waveform compared with river basin development steep, crest discharge increases, and rain disaster takes place frequently.The not expansion of moisture roofing, oozes under minimizing rainwater, has reduced the supply of rainwater to underground water.The geometric properties of building has aggravated the tropical island effect in city; The increase of Permeable stratum area, by soil evaporation, the moisture that plant transpiration and water surface evaporation enter atmosphere reduces, and causes the reduction of urban air relative moisture; The comprehensive function that tropical island effect and relative air humidity reduce can cause the minimizing of rainfall again, the shortage of water resources of aggravation regional area.The frequent particulate in air occurring exceeds standard in recent years, and by evaporation, to enter circulatory system deficiency relevant with rainwater.
Many unfavorable factor impacts, reduce city dweller's quality of life above, threaten resident's security of the lives and property, become the factor of restriction urban development.Therefore, in Process of Urbanization, should change traditional rainwater-collecting discharging modes, increase moisture, water, rainwater utilization area on the spot, maintain or repair the hydrological characteristics in city development region, reduce to greatest extent the impact of urbanization on environment, make urbanization process present the feature of conservation culture.
Green roof produces under such background, and when thickness of filter bed is 10cm left and right, green roof can rainfall interception amount 65%.Greatly delay rainwater flood peak peak value and arrive the time, smooth water catchment area peak value, reduces peak flow, has alleviated water catchment area, downstream and has flooded.Green roof, has also increased evaporation discharge simultaneously, has increased airborne humidity, has reduced the amount of suspended particulate substance in air, has effectively purified air.
Summary of the invention
In order to carry out scientific and reasonable greening to building roof, antiseepage, is effectively detained rainfall, science is got rid of unnecessary rainwater, the hypothallus humidity that keeps vegetation growth, promotes vegetation growth, maintains enough life cycles, the utility model provides a kind of rainwater to keep and the green roof of air cleaning module, solved the current shortage of water resources of China, rainfall runoff is large, and rain flood risk is high, city haze, the present situation that atmospheric pollution is serious.
For realizing effective utilization of rainwater, be detained and promote evaporation, the utility model adopts modular construction, and each module is of a size of 1m * 1m, when a plurality of modules are used together, between module and module, by the flange on drainpipe, is connected, expanding area.
Rainwater that the utility model provides keeps with the green roof of air cleaning module by waterproof, waterproof, water, discharge structure pallet, root growth key-course, and light-weight plant growth substrate layer, proofing dust and protecting filter course, vegetable layer forms, wherein:
The internal placement of described waterproof, water, discharge structure tray bottom has water, drainage groove, and the outer setting of waterproof, water, discharge structure tray bottom has collection pipe, and water, drainage groove are connected with collection pipe;
Described root growth key-course is positioned on water, drainage groove;
Described light-weight plant growth substrate layer is positioned on root growth key-course;
Described proofing dust and protecting filter course is positioned on light-weight plant growth substrate layer;

The utlity model has following advantage:
1, modularization, can plant in advance, and unit is transplanted, and implements engineering construction fast, easy for installation, is applicable to the roofing of any exposed roofing, commercial building, residential building, underground parking etc.
2, drainage system is connected convenient with the original storm-water system of building.
3, consider antiseepage, prevent that root system from entering unpredictable region, punched-type support holder structure, effectively controls water, when keeping humidity, has extended the life-span of system.
4, the rooftop zoology system that the utility model forms can effectively be utilized rainwater, filters, and clean air, improves air quality, reduces urban heat land effect; Energy-saving and cost-reducing, blocking-up electromagnetic radiation, the diversity of building the protection ecosystem.
5, simple in structure, be convenient to install maintenance operation; Flexible design, south, the north all can adopt.
6, economical and practical, both can extend life-span on existing structure roof, can upgrade at any time.
