Rain penetration-discharging integrated ecological system
The present invention relates to a kind of system that utilizes of rainwater resource, the rainwater resource of particularly building the sub-district utilizes system.
In the city, the rainwater that drops to ground or roofing directly is disposed to the municipal drainage pipe network through the grate gutter inlet on ground or the ditch on ground, has strengthened the rainfall runoff in city like this, has increased the discharge pressure of city planting ductwork.Especially pull down and remove a building for reconstruction in current Urban Large scale, in the upsurge in construction of a large amount of newly-built sub-districts, buried storm sewer need be laid in many newly-built sub-districts, and docks with existing municipal drainage pipe network, this has more increased the load of existing municipal drainage pipe network.And on the other hand, because that most of rainwater fails to reflux is underground, the groundwater table in the city reduces year by year significantly, and the minimizing of underground water source makes the city become withered isolated island, has worsened urban ecological environment.
At present, the way that some head it offs are arranged is that the rainwater of setting up rainwater collecting pit and non-osmosis type in the building sub-district is collected pipe network, and the rainwater of collecting is recharged to underground as sub-district afforestation water through behind the sedimentation and filtration; But for the effect that reaches smooth draining and infiltration and prevent that pipe network from stopping up; Ground need be provided with more rainwater inspection well, link to each other with short pipeline between well and the well, and the quantity of rainwater inspection well is too much; Not only can increase the cost of cell infrastructures; And can influence the landscape effect on ground, and the rainfall load that directly can cause in the pond to be born with the pipeline connection is big, also can't reach good osmotic effect.What is more, attacks suddenly when raining heavyly when running into, because impeded drainage at short notice; A large amount of rainwater and road surface foreign material pour in inlet for stom water; Just cause easily that inlet for stom water stops up and local low-lying land area water is dark excessively, cause the regional traffic paralysis, even the rain big flood evil in zone occurs.To sum up, existing way generally just adopts the means or the local penetration utilization of discharging fully or recovery fully to rainwater, does not still have a kind of rain penetration-discharging integrated system of maturation, and this problem needs to be resolved hurrily.
