Description

Biological detention pond suitable for pavement below

Technical Field

The utility model relates to a biological detention pond suitable for pavement below belongs to environmental engineering technical field.

Background

Along with the rapid urbanization development, the type of the urban underlying surface is changed greatly, the original large-area water-permeable ground surface is gradually covered by water-impermeable materials such as buildings, hardened pavements and the like, and the way of the rainfall runoff infiltrating into the ground is blocked, so that the peak flow of the runoff is increased, and the urban inland inundation is caused frequently. Meanwhile, when the rainwater runoff scours the ground, a large amount of pollutants are carried and are gathered into urban water, so that the urban water pollution is aggravated. Because the biological detention pond can effectively reduce the runoff of rainwater and improve the quality of rainwater runoff, the biological detention pond is widely applied to areas such as construction areas, residential districts, suburbs and the like at present.

The bioretention pond bears the functions of peak clipping, emission reduction and stagnant storage purification in sponge city design and is also a key and difficult point of design and construction. Traditional biological detention pond is located the greenery patches more, and is higher to setting up position, vertical, water conservancy diversion requirement, sets up inappropriately to be difficult to converge or influence the view effect, and the lower landmass of greenery patches of rate then is difficult to implement traditional biological detention facility and carries out runoff control.
