Description
Technical field
The present invention relates to rainwater pollution controls and Rainwater Resources to utilize field, more specifically to a kind of progressive
The recessed greenery patches of rotary island.
Background technique
Since China's pumping equipment majority is by the way of " arrange fastly fastly let out ", with adding for Development of China's Urbanization paces
Fastly, waterproof underlying surface increases significantly in city, causes rainfall runoff coefficient to increase, time of concentration shortening, causes rainfall runoff
Peak flow constantly increases.Along with atmosphere pollution settles, on ground the problems such as the accumulation of pollutant fine day, rainwater resource waste and
Runoff pollution caused by Rainwater Initial scouring effect is also got worse, at the same time, extreme weather caused by tropical island effect etc.
Result in heavy rain take place frequently, storm intensity increase, cause urban waterlogging serious, caused to the social economy and resident living in city
Greatly damage.
Concave herbaceous field technology is that low influence the important of utility strategies practices part.Concave herbaceous field refers in Green Space Construction
When, make greenery patches elevation lower than surrounding ground height appropriate, in favor of the remittance of periphery rainfall runoff.Concave herbaceous field not only may be used
Increase urban water-through underlying surface ratio, water permeability is good, and construction cost is close with conventional greenery patches, and there are Rainwater Resources to utilize
And improve the function of urban environment.
Although existing all kinds of concave herbaceous fields are able to satisfy the processing to Rainfall Runoff to a certain extent, increase
City underlying surface area, but there are still apparent shortcomings and deficiencies, if green function is too simple, cannot be removed effectively just
The problems such as major pollutants in phase rainwater, concave herbaceous field water-holding capacity is insufficient in exceptional flood peak.
Summary of the invention
For the purification of main Runoff contaminants present in existing concave herbaceous field, insufficient, flood peak is adjusted not perfect, green
The problems such as rainwater runoff gathering forms stagnant water in ground, and green function is damaged, the present invention provides a kind of progressive rotary island is recessed green
Ground.It can be such that rainwater runoff pollution object absorbs by greenery patches multiple purifying, storm runoff flood peak of regulating and storing, and keep Rainwater Resources sharp
With.
In order to achieve the above object, the technical scheme adopted by the invention is that: providing a kind of recessed greenery patches of progressive rotary island includes
Greenery patches peripheral annular strainer, road surface greenery patches, the arc-shaped greenery patches of first layer up concave type that elevation successively successively decreases, second layer up concave type circle
Arc greenery patches sets the overflow pipe with filter screen in the arc-shaped greenery patches of second layer up concave type, and greenery patches bottom is primary soil,
It is interior be equipped with PP module rainwater storage tank and Greenland Irrigation system, the Greenland Irrigation system include elevator pump, PVC water-supply-pipe and
Spray head.
The road surface annular filter screen material is wire or nylon yarn, is highly 30 ~ 50cm.
The herbaceous plant of growth belt catharsis on the road surface greenery patches, and the spray head of Greenland Irrigation system is set.
Kind is implanted with the herbaceous plant and water plant of catharsis, connection on the arc-shaped greenery patches of first layer up concave type
The height difference of highest point and its minimum point at the arc-shaped greenery patches of second layer up concave type, is planted that vegetation is resistance to be flooded the time and can bear by it
Maximum height.
The arc-shaped greenery patches of second layer up concave type and the arc-shaped greenery patches junction of first layer up concave type is 20 ° ~ 60 °
Arc slope surface, the thereon aquatic vegetation of growth belt catharsis are equipped with overflow pipe at center.
The overflow pipe nozzle is equipped with the filter screen of nylon yarn, and overflow pipe setting is arc-shaped green in second layer up concave type
At ground center, height is that lowest part plants that aquatic vegetation is resistance to be flooded the time and can bear in the arc-shaped greenery patches of second layer up concave type on the ground
Maximum height, the rainwater higher than overflow pipe enters overflow pipe, is delivered to the storage of PP module rainwater storage tank by primary soil.
The primary soil is located at greenery patches peripheral annular strainer, road surface greenery patches, the one or the two layer of arc-shaped greenery patches of up concave type
Bottom, it is interior to be equipped with PP module rainwater storage tank.
The PP module rainwater storage tank is located in primary soil, and top is apart from the arc-shaped greenery patches bottom of second layer up concave type
10 ~ 15cm of portion, surrounding wrap up waterproof geotextile layer, elevator pump, the PVC water-supply-pipe of built-in Greenland Irrigation system.
The elevator pump of the greenery patches spray irrigation system is located at PP module rainwater storage bottom of pond portion, and the connection of PVC water-supply-pipe is promoted
Rainwater indentation water delivery supervisor is redistributed to branch pipe by pump, water pump, and branch pipe passes through PP module rainwater storage tank pond body and primary soil,
The rainwater of storage is promoted to road surface greenery patches and passes through spray head recharge to greenery patches.
In conclusion the invention has the following advantages that
1, the present invention may be provided at the low rainwater catchment of topography, such as be located at the low traffic intersection junction of topography, not only can be with
Rainwater pollution is handled, flood peak is adjusted, utilizes Rainwater Resources, can also play the role of directing traffic, while beautifying landscape；
2, for rainwater by greenery patches peripheral annular strainer, road surface greenery patches, the first layer up concave type that elevation successively successively decreases is round in the present invention
Arc greenery patches, the progressive filtration, purification in the arc-shaped greenery patches of second layer up concave type, more clean rainwater can enter to be seeped into underground benefit
It fills underground water or is stored to PP module rainwater storage tank, the rainwater of collection can replace municipal water sprinkling irrigation greenery patches when needed, make rain
Recycling of water resource utilizes；
3, the water-holding capacity of concave herbaceous field has fully considered that plantation the resistance to of vegetation floods the time in the present invention, makes rain water pollutant can
While to obtain effectively removing, the purification function in greenery patches itself will not because amount of rainfall excessively caused by anoxic, cause in greenery patches
Water becomes stagnant water and is destroyed, while also having broken the limitation of the recessed depth of concave herbaceous field；
4, the overflow pipe nozzle that PP module rainwater storage tank is connected in the present invention is equipped with filter screen, can will be multiple net by greenery patches
Rainwater after change filters again, and also relatively simple economy, overflow pipe can also make PP module rain simultaneously for the cleaning replacement of filter screen
Air in water storage pond is maintained at circulation status.
