Description
Technical field
The invention belongs to Rainwater Resources to utilize field, and in particular to a kind of building roof rainwater pushes back benefit lithic drainage
System.
Background technique
Application of Urban Rain Water mode has at present: rainwater accumulating reuse, artificial two broad aspect of retention osmotic technology.
Rainwater accumulating reuse can be divided into secondary reuse and covering underground water etc., and artificial retention osmotic technology can elaborate
For permeable pavement, biological gaseous-waste holdup system, Green Roof, grass planting ditch, concave herbaceous field, plant buffer strip etc.；It is each in this two aspect
Mode stresses function difference, but generally to seep, it is stagnant, store, be net, based on, to largely play the money of rainwater
Source utility value.
But for the problem that above-mentioned two aspects technology is in terms of increasing underground water containing storage capacity, there is space utilization contradiction,
Wherein artificial retention osmotic technology (seep, is stagnant) need to lay related measure, occupy city larger space；Rainwater accumulating reuse (store,
Only, with) reservoir need to be built, occupy urban land, also relate to insufficient space problem, city space utilize between there are lances
Shield.Moreover, above-mentioned technology (in addition to covering underground water) principle essentially increases the rainwater residence time, make rainwater is naturally lower to seep, but
This process time period is long, to quickly increase underground water containing storage capacity, the problems such as urban flooding is effectively relieved, effect is unobvious.
However, existing rainwater covering underground water technology has advantage in terms of quickling increase underground water containing storage capacity；But
There are still deficiencies for this approach, and on the one hand current rainwater covers underground aqueous mode, is all made of and first harvests, after-purification, covers again
Mode, but during harvesting, so that dropping to the losses of potential energy of building roof rainwater；And the adjoint confluence in harvesting
It collects, the processes such as store for a long time, easily deteriorate Rainwater Quality, cause rainwater secondary pollution, be more difficult the problem of purification, increase
The utilization cost of rainwater.On the other hand, the common method of rainwater covering underground water has surface infiltration method and two kinds of pipe well injection method,
But above two method has shortcoming；Surface infiltration method based on infiltrating naturally, long period, and to place (infiltration
Property, occupied area) require it is high；Pipe well injection method, and gravity injection method, priming by vacuum hair and enhancing perfusion method can be divided into；Wherein
In having three ways, such as that pushing back benefit is, the highest one kind of efficiency is covered, compared with without benefit is pushed back, the left side 15%-200% is can be improved in covering efficiency
It is right.But the large-scale covering equipment such as force (forcing) pump, water tank need to be laid by pushing back benefit, and the external world is needed persistently to provide electric energy, using at
This height.Based on above-mentioned two aspects problem, the comprehensive utilization cost of rainwater is increased.
Summary of the invention
In order to solve the problems in the existing technology, the present invention provides a kind of building roof rainwater and pushes back benefit underground water
System, to solve the problems, such as that Urban Underground water shortage, waterlogging take place frequently in the prior art, rainwater comprehensive utilization is at high cost.
The technical solution of the present invention is as follows:
A kind of building roof rainwater pushes back benefit ground water regime, including rain collector, rain pipe, rainwater purification system
System and underground water push back complement system；Rain collector, rainwater purification system, underground water push back complement system and pass through rain
Water pipe, which is sequentially connected, to be connect；Rainwater on building roof carries out quick after rain collector is collected into rainwater purification system
Purified treatment, purified rainwater enter underground water via rain pipe and push back in complement system, finally cover to underground.
The rainwater purification system from top to bottom successively includes rainwater filtering device and rainwater purification apparatus.The rainwater is net
Changing system quantity includes but is not limited to 1 set, and is mountable to the preceding any position of filter pipe.
It includes well casing, filter pipe, filter material that the underground water, which pushes back complement system, and purified rainwater is transmitted via well casing
To filter pipe, enter in filter material through the aperture of drainage pipe surface, finally covers to underground.
Radiation well casing is additionally provided on the filter pipe.The radiation well casing is set as horizontal or tilts down.
The underground water pushes back complement system and is laid in the underground reservoir water surface or less.
Roof superelevation is set on the building roof, is provided with Overflow drainage hole at roof superelevation.
The rain collector includes but is not limited to roof drain, sump, rainwater diversion slot or water pump；Rainwater-collecting
Device includes but is not limited to 1 set in the installation number of building roof, and its mountable any position in building roof.
The filter material material includes but is not limited to cobble, gravel, filter membrane.
Beneficial effects of the present invention:
1, what the present invention may be implemented urban architecture rain water on roof pushes back benefit to underground water.To building roofing rainwater
Collect, fast purification processing on the basis of, take full advantage of the head pressure that building roofing rainwater has itself, not by
Under the premise of extraneous measure and energy, benefit is pushed back to underground water, research advances can be effectively improved, alleviate urban groundwater
The problem that shortage, waterlogging take place frequently；
2, the present invention is not required to be arranged in earth's surface when pushing back urban architecture rain water on roof on the spot benefit to underground water
Other Engineering is handled, and redundant space is prevented take up, can effectively save rainwater comprehensive utilization cost.
