Description

A kind of improved sponge urban road catchments deodorization pit device

Technical field

The utility model is related to a kind of urban water conservation technical field.

Background technology

Sponge cityMove towards practical application in China from concept.Sponge city is that new generation of city storm water man- agement is general Read, refer to that the aspects such as the natural calamity that city is brought in adaptation environmental change and reply rainwater have good elasticity, when rainy The water storing is discharged when needing and is used by water suction, retaining, infiltration, water purification.Under conditions of primitive nature, most of Rainwater by ground absorption and permeate the ground, then evaporated by earth's surface and plant surface, returned in air, unnecessary rainwater from Earth's surface lentamente comes together in streams rivers, enters lake ocean.But, the development ＆ construction in city change this Natural Circulation, Because waterproof roofing and ground continuously quickly increase with the process of urbanization, the ground that can drink up the rain and The water surface drastically reduces, and the infiltration of underground water is even more scarcity, thus leading to being continuously increased of rainwash, increasing waterlogging and threatening.No The rainwater that method flows into soil collects formation runoff on ground and enters municipal drainage system, but the increase of rainwash is it is meant that more The pollutant through urban surface for the rainwater of many cleanings originally is polluted, and the pressure of drainage pipeline is consequently increased.Simultaneously because For urban discharging pipeline for hard facility it is difficult to coordinating changeable rainfall and changing discharge capacity, so occurring draining not enough and producing The situation of raw waterlogging.Especially in the case that China's early stage builds inadequate specification, the pipe drainage system that city is relied on is in fact Can't bear the heavy load, therefore waterlogging frequently occurs.The principal advantage in sponge city is to be collected utilizing by rainwater " turning waste into wealth ". Singapore's shortage of water resources, water resource 211m per capita, account for world's penultimate, this state utilizes cistern to collect rainwater recycle Using the dependence to running water decreases 40%.Review domestic many cities, the exhaustive exploitation underground water because water resource lacks, lead Groundwater run off is caused drastically to reduce, result is that urban underground space cavity in a large number, surface subsidence, endangers life of urban resident. Rainwater infiltration and rainwater reuse are emphasized in sponge city, enhance the demand feeding and reducing underground water to underground water simultaneously, protect The level of ground water of card safety, reduces the risk of surface subsidence.Blend collection under rainwater being carried out due to sponge city, decrease The dependence to city planting ductwork for the city, puts into so as to reduce pipeline laying., passed with replacing pipeline upgrading taking U.S.'s Portland as a example System drainage system will expend $ 2,500,000, and implement sponge sewerage system only $ 2,000,000, greatly reduce pipe network and put into.Sponge city Rainfall runoff is mainly received by imbibition under nature in the form of concave herbaceous field by city, also adjusts while city " cavernous body " increases Save urban ecology.

In the unitary construction in sponge city, catch pit or Ji Yukeng are common devices, and existing catch pit structure is relatively For simple, there is a problem of that long-term storage rainwater is smelly.

Utility model content
