Description
Technical field
The present invention relates to outdoor drainage, rainwater processing technology field, relate in particular to a kind of flat roof rain water regulate and store device and the method for regulating and storing.
Background technology
Along with the fast development of urbanization, waterproof region area increases sharply, blocked rainwater under ooze passage, destroyed the Natural Circulation process of rainwater. The design of tradition drainage system against rain is taking " row soon " as guiding theory, and result causes the increase of downstream drainage pipeline pressure, combined sewer overflow (CSO) and waterlogging to take place frequently. Particularly, in China, heavy rain causes drainage pipeline networks overflow event constantly to occur in recent years, and combined sewer overflow pollutes to water body and brought serious pollution, has had a strong impact on resident living and has brought huge economic loss. Therefore, traditional drainage system against rain has been difficult to adapt to the demand of urbanization fast development. Conventionally cause that the principal element that city waterlogging and combined sewer overflow occur not is the water yield, but the time that the size of peak flow and peak value occur. Developed country is for the above-mentioned rainwater problem facing in Process of Urbanization, a series of new storm water management theories have been proposed, as low impact exploitation (LID), sustainable drainage system against rain (SUDS), water sensitivity urban design (WSUD), green infrastructure (GIS) etc., these theories are all emphasized in source, place by distributed facility control rainfall runoff, but because China's Land Development intensity is generally higher, limit to a certain extent applying of these measures. For tackling these complicated urban rainwater problems, the Current Situation such as large in conjunction with China's mining inetesity that at present some cities face, place is limited, waterlogging takes place frequently, combined sewer overflow is seriously polluted, the facility of regulating and storing is more and more used in the management of urban rainwater, regulate and store facility as a kind of effective method of tackling city waterlogging and combined sewer overflow pollution, utilize in system constructing and draining waterlogging control program and occupy consequence in Urban Storm Flood control.
The facility of regulating and storing can be divided into natural facility and the Artificial Regulation facility of regulating and storing, and self-assembling formation is original often just exists for the natural facility of regulating and storing, as swag, wetland, river course, lake etc. Artificial Regulation facility is the various facilities of regulating and storing through artificial design, construction, as storage pond, the tunnel of regulating and storing, sunk type square, parking lot, landscape water body, pipe network are regulated and stored etc. Owing to not taking effective protection measure in most domestic Process of Urban Development; result causes the natural facility of regulating and storing to be landfilled or to take; city " sponge effect " weak or lose; while bringing inevitable destruction when naturally regulating and storing due to urbanization fast, engineering is regulated and stored will become one of effective measures of urban rainwater management. The facility of regulating and storing of Engineering-type can be alleviated the waterlogging pressure increasing due to Site development, and engineering is regulated and stored facility often because the problems such as occupation of land scale is large, cost of investment is high, land used restriction are restricted in actual applications. China's big and medium-sized cities roofing area generally accounts for the 30-60% of urban land, and Urban roof is not only a unemployed huge space resources, is also one of main contributions person who aggravates in Site development process urban rainwater problem simultaneously. Regulate and store in source in roof, the effect that performance is regulated and stored is more effective, and construction cost is low, is convenient to maintenance management, and can effectively utilize Urban Roof space resources. Therefore, in the higher old town of urban architecture density or other high-density development region, regulate and store and can be used as one of method of controlling city waterlogging and combined sewer overflow in roof.
Summary of the invention
Single in order to solve existing outdoor drainage system function design, ignore comprehensive storm water management, the city ability of regulating and storing is low, meet easily waterlogging of rain, combined sewer overflow pollutions etc. are to people's person, the severe contamination of the harm that property brings and the water body that causes and the destruction to ecological environment, effectively realize the controlled discharge to rainwater, peak flow is cut down, alleviate the pressure of city present situation pipe network, effectively reducing city waterlogging risk and combined sewer overflow pollutes, increase the sponge function in city, rain water on roof is filtered and can utilize facility to combine with rainwater recycle simultaneously, saving water resource to a certain extent, alleviate urban water anxiety. one of object of the present invention is to provide a kind of flat roof rain water device of regulating and storing, two of object of the present invention is to provide a kind of flat roof rain water method of regulating and storing.
For achieving the above object one, the present invention has adopted following technical scheme:
A kind of flat roof rain water device of regulating and storing, comprise the pipeline section of regulating and storing, connect pipeline section, the described pipeline section of regulating and storing arranges multiple outlets of regulating and storing from top to bottom, described connection pipeline section for will described in the pipeline section of regulating and storing be connected with building roofing rainwater down pipe, described in the regulate and store caliber of pipeline section be greater than the caliber of building roofing rainwater down pipe; The described outlet of regulating and storing is for the line style hole of strip or circle or the slotted eye of dispersion.
Be provided with and enclose filter frame in the periphery of the described pipeline section of regulating and storing, filtration is housed in filter frameFiller, filter packing can adopt gravel, cobble or other to have the material of filter effect; Described enclose filter frame entirety can be for circular, rectangle orOther shape。
