Description
Technical field
The present invention relates to sponge urban construction and Rainwater Resources to utilize technical field, and in particular to one kind is used for sponge city
Ability of swimming ecologic rainwater storage pond is strained in the floating of city's construction.
Background technique
In recent years waterlogging is frequent in China city, there is the demand drained rapidly for rainy season mainly due to city, but encounters strong
When the especially a-hundred-year heavy rain of rainfall, original municipal administration Storm Sewer Network is not able to satisfy the demand drained rapidly, so pipe network is held
The pressure of load is continuously increased, and how quickly and on the basis of not influencing original pipe network, is solved the problems, such as urban waterlogging, is become present
The emphasis of concern.
Currently, the mode of city rainfall runoff mostly uses greatly the mode shut off, although this mode can drain ground rapidly
The extra runoff of table, but this mode is more demanding to the bearing capacity of Storm Sewer Network, and pipe network system original for city
System is affected, and construction cost is higher, and lower to the utilization rate of rainwater.Although present more common engineering measure be
Rainwater storage tank is added to play and alleviate Storm Sewer Network discharge pressure and storage rainwater in case benefit in the middle rear end of Urban Rainwater Pipe Networks
Purpose, wherein the rainwater storage tank being previously mentioned, setting purpose is when rainy season set, it can receiving rainwater, again
Storm Sewer Network pressure is shared to reduce the risk of urban waterlogging；After rainy season, and water can be discharged to alleviate urban water pressure.
This way, smaller for the influence of original Storm Sewer Network system, the LID (low influence exploitation) for meeting sponge urban construction is theoretical.
But the generally existing pollutant long-term existence in rainfall runoff brought by pollution of area source of common rainwater storage tank is in water
Smelly after causing pool bottom sludge to precipitate in body for a long time, cleaning difficulty is big and is easy the problems such as again resulting in pollution.
Summary of the invention
