Abstract
The utility model discloses a kind of concave herbaceous field and the well lids for concave herbaceous field, including coating and the rainwater collection pool being set to below coating, further include spilling water well, the spilling water well includes top well body and lower part well body, the lower part well body is connected with the upper end of rainwater collection pool, and top well body runs through the coating；It is arranged with outer barrel, elevation components, inner cylinder inside the top well body successively from outside to inside, the outer barrel is connected with top well body inner wall, and the outer barrel is connected with the lower end of inner cylinder by bottom plate, and the region between the outer barrel, inner cylinder and bottom plate forms accommodating chamber；The surface of the top well body and elevation components circumferential direction is porous structure；Multiple floating bodies are connected on the outer wall of the elevation components circumferential direction.The purpose of this utility model is that solving spilling water well well head in concave herbaceous field is easily contaminated the technical issues of object blocking causes rainwater-collecting difficult, while reaches effectively adjusting rainfall runoff and realize rainwater purification, savings and utilize function.
Description
Technical field
The utility model belongs to sponge urban construction field, more particularly, to a kind of concave herbaceous field.
Background technology
In recent years, China's urban storm product damage caused by waterlogging evil takes place frequently, and traditional urban road generally existing is seriously polluted, rainwater money
The problems such as source stream is lost, pressure of drainning off floodwaters is big, the urban waterlogging continuously broken out causes serious life and property loss and ecological disruption.
Sponge city is new generation of city storm water man- agement concept, refers to the nature that city is brought in adaptation environmental change and reply rainwater
Disaster etc. has good " elasticity ".
Rain drop erosion ground can generate runoff pollution, but pollution level it is lighter can be used as after processing urban afforestation,
Wash away the water source of road.It is mainly that roof rain water collecting, urban pavement rainwater utilization, city are green to the utilization technology of rainwater at present
The rainwater on ground continues with.Concave herbaceous field is the public lawn that a kind of elevation is less than surrounding road surface, and theory is using recessed
Open space accept and storage rainwater, reach recharge of groundwater, regulated flow and flood detention and cut down Runoff contaminants work
With.Rainwater storage tank is a kind of rainwater-collecting facility, and main function is that the peak flow of rainfall runoff is kept in it, works as maximum
Flow again discharges rainwater from storage pond after declining at leisure.Rainwater flood peak can be evaded, realize that rainwater recycles, and energy
Pollution of the initial rainwater to receiving waters is avoided, positive effect is played in the draining scheduling between drainage.
Existing concave herbaceous field can generally set a spilling water well among greenery patches, and the well lid of spilling water well is equipped with hole,
While facilitating the rainwater to be flowed into spilling water well, a part of rubbish is retained.But rainwater enters from concave herbaceous field surface overflow
During spilling water well, there may be the well lid orifice area of overflow well is inadequate or rubbish is too much by aperture when amount of rainfall is excessive

It changes；When accommodating chamber 16 needs cleaning, the first well lid can be also opened.The well lid can be applied to the spilling water well of any concave herbaceous field
On, it solves spilling water well well head and is easily contaminated the technical issues of object blocking causes rainwater-collecting difficult, applicability is wide, and is easy to
It replaces.
The specific work process of the utility model：
As shown in Fig. 2, enlarged diagram when elevation components do not rise.After raining, a part of rainwater is under road inflow
Enter overflow well 2 from the two sides of top well body 3 after concave green belt, a part of rainwater by being seeped into rainwater collection pool 1 under coating,
Some rainwater enters overflow well 2 from the first well lid and the second well lid.Wherein, the rainwater entered from the first well lid directly flows
Entering in rainwater collection pool 1, the rainwater entered from the second well lid is flowed into accommodating chamber 16, and rainwater is collected in accommodating chamber 16 on one side,
On one side by the porous inflow overflow well 2 of 16 bottom plate of accommodating chamber setting.
As shown in figure 3, the enlarged diagram after elevation components rising.Rain continues to descend, when collection rainwater in accommodating chamber 16
Speed be more than from bottom plate it is porous leak into overflow well 2 speed when, the rainwater collected in accommodating chamber 16 is more and more, accommodating chamber 16
Multiple floating bodies 18 and contacting rain water on the circumferential outer wall of interior elevation components 4, because floating body 18 is connected to the outer wall of elevation components 4
On, elevation components 4 is driven to rise after the buoyancy that floating body 18 is provided by rainwater, encounter until floating body 18 and be arranged on 18 top of floating body
The baffle 17 of buffer protection function is played, elevation components 4 stop rising.At this point, the entire well body height on top increases, increase
Rainwater enters the area of overflow well 2, and rainwater from the porous inflow of 4 peripheral surface of elevation components and then can also be flowed into spilling water well
In 2.If the porous of top well body 3 is blocked by rubbish, the elevation components come are raised inside top well body 3 later 4 weeks
To surface it is porous be also used as it is spare.
As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiment of the utility model only, not
To limit the utility model, any modification made within the spirit and principles of the present invention, equivalent replacement and change
Into etc., it should be included within the scope of protection of this utility model.
