Description
Technical field
The present invention relates to a kind of automatic control pouring application apparatus, particularly relating to a kind of planted roof that is used for is the Automatic Cycle irrigation device that the required moisture of plant growing is provided.
Background technology
In recent years, along with the fast development of China's economic construction, being surging forward of real estate industry, the urban architecture emerge in multitude, the high buildings and large mansions as standing in great numbers, the city space that makes people depend on for existence becomes more and more littler, also forces greenery area more and more littler.Especially densely populated big and medium-sized cities; The greenery area on plane is pitiably little; Also in addition rural population constantly pour into the city, various commercial facilitys concentrate on many factors such as trend that launch in the city again, are nibbling the greenery area as the important environmental assets in city in a large number.Therefore, produce various cities public hazards such as tropical island effect, pernicious gas, environmental deterioration, caused the continuous decline of urban life environmental quality.For this reason, in limited land resources, how to improve greenery area and become the important subject of urban development with preserving the ecological environment, various places research institution studies diverse ways one after another and material manages to solve this difficult problem.Simultaneously, also caused the great attention of China governments at all levels.
Utilize the end face plantation green plants of various roof of buildings and Other Engineering and set up various functions place; Can slow down effectively the city " tropical island effect ", increase oxygen content in the urban atmosphere, be absorbed with harmful substances, alleviate atmospheric pollution, regulate ecotope, beautifying city view; Also various economic crops are planted in the space of deck capable of using, increase economic well-being of workers and staff, foundation activity (motion) place, give full play to the effect that utilizes and control urban rainwater, the service life that prolongs the various materials of roofing.
At present, the main structure of the roof planting system that China is commonly used by infrastructure layer, screed-coat, heat-insulation layer, the resistance of anti-plant roots layer, watertight composition, white-out water layer, filter course, plant soil layer, green planting layer formed, and sees Fig. 2.The roof greening ecosystem is built in unscreened space, is that sleet water is collected maximum places throughout the year, the snow in the especially southern rain and the north, and the absorptive amount of plant substrates layer is very limited.So how the unnecessary sleet water of recycle keeps the plant of roofing not waterlog for a long time at rainwater; Rainwater is not non-irrigated after a little while; Can both supply with suitable moisture throughout the year, make all kinds of plant normal growths, be a major issue that will solve in the roof greening ecosystem.Though in year surplus the roof greening work of China has carried out ten, the manual watering is still depended in the later stage maintenance of roof greening plant; The result who obtains improves management cost, wastes a large amount of manpower and financial resources, and plant can not finely be grown; Thirst, situation withered, that freeze to death is very serious, when winter gave place to spring, greening can not germinate; Can not get good result, make people lose confidence, also had a strong impact on the development of roof greening cause roof greening.
Summary of the invention
The objective of the invention is to,, thereby a kind of a kind of Automatic Cycle irrigation device that is used for roof greening is provided to the deficiency of above-mentioned existing roof greening technology existence;
This device takes to dredge, arrange, hold and combine, and detects automatically, control is carried, the mode of pouring at any time, makes full use of the white-out water system of layer structure, surplus, lack of water resource is carried out Automatic Cycle, the comprehensive adjustment utilization; Accomplish to control correctly timely, time saving and energy saving, practice thrift the modernized maintenance management of maintenance cost and water resource, practicable extensive roof greening system;
The objective of the invention is to realize like this:
