Embodiment
To further illustrate content and feature of the present utility model, it is illustrated with reference to accompanying drawing embodiment, the present embodiment is
For illustrating the utility model, and it is not limited to limit the scope of the utility model.Implementation condition in embodiment can be according to tool
The situation of body plant equipment is adjusted.
The present embodiment selection implements pond of the present utility model of regulating and storing under certain city riverfront greenbelt.Terrain slope is about
0.6%.
Pond of regulating and storing belongs to rainwater storage structures.Its volume scale computational methods mainly has two classes：Equivalent is held with pond
Empirical formula method and the frequency analysis method based on model for drainage system.The utility model is according to control runoff pollution and abatement flood
The different situations of peak flow, consider the rainfall intensity of location, rainfall pattern, last, the silt of frequency and rainwater sweeps along ability
Etc. the influence of factor.Pond dischargeable capacity of regulating and storing (each pond body dischargeable capacity sum) is calculated using equation below.
In formula：V --- storage pond dischargeable capacity (m3)；
α --- deprivation coefficient, value are the ratio between storage pond downstream design discharge and upstream design flow；
Q --- storage pond upstream design flow (m3/min)；
B, n --- Rain Intensity Formula Based parameter；
T --- rainfall duration (min)；
T=t1+t2
t1--- ground inlet time (min), it should be calculated and determined according to terrain slope, charge for remittance distance and floor type, one
As use 5~15min；
t2--- rainwater fashionable colors (min) in pipe duct.
According to result of calculation, the pond dischargeable capacity of regulating and storing under the city riverfront greenbelt is defined as 5000 tons, and synthesis is examined
Consider landform gradient, construction land, rainwater utilization system elevation, each monomer pool volume and number are determined to integrate, N is 5 to regulate and store water
Pond, that is, play purification, the monomer pond of pondage capacity is 5, and monomer pond 1-5 scale is 1000 tons, and the monomer pond 6 of most end is first rain
Collecting pit, volume scale is not counted in, 6 monomer ponds in the underground staged chain rainwater storage pond, with landform gradient chain
Build.Monomer pond is designed as hexagon, and the bottom of pond gradient is set as that 3%, monomer Chi1-6Chi grow 20 meters, and wide 12 meters, pond is deep 4 meters, phase
Border on the river provided with 3 meters of the discrepancy in elevation (being beneficial to wash away) between pond, monomer is connected between pond using rectangular well, slide valve management.
As shown in figure 1, whole staged chain is regulated and stored, pond is made up of monomer pond 1~6, end to end, is arranged into chain.
6 monomer ponds 1~6, according to slope aspect, Cheng Yilie, staged is along slope arrangement step by step.
The pond average height H that regulates and stores is 3.5 meters, and maximum height is 4 meters and (bent：Chi Shen is 4 meters, and what meaning is this height be
ThinkRefer to that pond is deepIf if the depth of pond, pond depth is changed to), according to terrain slope, open-cut, whole pond of regulating and storing is placed in
Below earth's surface, buried depth h=4~4.5 meter in each monomer pond.
In order to facilitate the utilization of rainwater, the present embodiment rainwater storage pond is arranged on the side of urban green belts 19, by returning
Rainwater is delivered to the irrigation system of greenbelt 19 with pipeline 15.
Rainwater enters seat of honour monomer pond 1 by urban rainwater main pipe through water inlet pipe 7, passes through monomer pond 2- successively downwards step by step
5, monomer pond 6 is finally entered, i.e., first rain collecting pit.
Regulate and store the stagger of each monomer pond 1,2,3,4,5,6 in pond, depth displacement is equal between monomer pond 1,2,3,4,5
For 3 meters.Using the pond body of stagger, there is larger advantage in terms of rainwater utilization, for neighbouring greenery patches 19, in upper
The monomer pond of higher position is swum, is used separately as the head-tank in downstream greenery patches.Solicit orders for body pond 1, monomer pond 1 passes through reuse pipe
Line 15 is connected to irrigation system 14, and reuse water pipe 15 is picked out by the end bottom position perforate 27 of monomer pond 1, into irrigation system
14, due to the discrepancy in elevation between the bottom of pond and irrigation system 14 in monomer pond 1 in the presence of 3 meters, rainwater can flow automatically into irrigation system in pond
14, realize gravity water conveyance irrigation.In this way, each pond body corresponds to one-level, pond body 2,3,4,5 with the irrigation system in downstream, one-level
Irrigation system 21,22,23,24 is corresponded to respectively, 2-3 rice be present between monomer pond 2-5 bottom of pond and corresponding irrigation system 21-24
The discrepancy in elevation, realize energy saving of the rainwater in terms of green area irrigation.
First rain is washed away by the squash type in monomer pond 1,2,3,4,5, reaches just rain collecting pit 6, amount of rainfall rises to necessarily
Highly, after first rain is contained substantially, the slide valve of the first rain collecting pit 6 of float switch control is fallen, and first rain is mothballed, sedimentation
In dislodger 12.
Lock well 8 is set between water inlet pipe 7 and first monomer pond 1, double-deck slide valve 9 is designed in lock well 8, manages rainwater stream
And silt flow.Lock well 8 is also provided between monomer pond, double-deck slide valve 9 is designed in lock well 8, management flows to next stage monomer pond
Rainwater stream and silt flow.
The shaft bottom of the lock well 8 set between water inlet pipe 7 and first monomer pond 1 is than the sinking 50cm of water inlet pipe 7, monomer pond end
The shaft bottom of the lock well 8 at end can intercept the larger silt of partial particulate, pass through sediment transport pipe than the bottom of pond sinking 50cm in the monomer pond
25, into sand sediment trap 11.
When running into the rainfall more than pond savings scale of regulating and storing, rainwater passes through the overflow that is set on monomer pond 1 and monomer pond 5
Pipe 10 enters nearby water system or drainage system.
The first rain sealed up for safekeeping is collected in first rain collecting pit 6, after rainfall stopping, opening management valve 26, first rain is through the row of pipeline 20
Enter domestic sewerage systems, enter sewage plant processing, such as Fig. 1, management valve 26 is arranged on the management lock well of first rain collecting pit end side
It is interior, the convenient management to first rain.
First rain collecting pit 6 such as Fig. 2, the middle part of first rain collecting pit 6, sand setting is set in bottom of pond using the design of partly open formula
Groove 12, the surface of riffler 12, the top of first rain collecting pit 6 set removable cover 18.The floor design of riffler 12 is that concave shape is bent
Face, facilitate vehicles while passing, after the first rain in first rain collecting pit 6 is drained, open removable cover 18, mechanical car's (such as bull-dozer) enters
Enter in riffler 12, clear up the silt of deposition.
Riffler 12 is set in first rain collecting pit 6, and the bottom of pond on riffler both sides is provided with 3% gradient.The utility model
It is not required to set manual cleaning passage, you can using mechanical chipping silt particle, saved human cost, convenient and efficient.
It is more that the utility model solves cistern puzzlement industry in terms of pond body flushing, the separation of first rain, rainwater purification reuse
The problem in year, zero power consumption auto-flushing of pond body was both realized, the separation management to first rain has been realized again, facilitates and isolate to collecting
Chu Yusong factory and office reason.Rareer, pond cleaning, silt cleaning work amount greatly reduce, except most end one-level pond, its
The rainwater accumulated in his pond is substantially not required to reprocessing can reuse.The utility model realizes just rain and collects separation, rainwater
Regulate and store, purify, reuse is completed in one group of structures.Make cistern in " regulating and storing ", " purification ", " utilization " several order process sections
Point realizes integration, imparts traditional cistern completely new concept, improves the efficiency of cistern.
