Potential energy pressurization rainwater row for sponge city stores system and method
Technical field
The present invention relates to a kind of potential energy pressurization rainwater row for sponge city to store system and method.
Background technology
Sponge city, is new generation of city storm water man- agement concept, refers to that city is adapting to environmental change and reply rainwater band
Natural calamity come etc. has good " elasticity ", also referred to as " water elasticity city ".International term is " low shadow
Ring exploitation storm-water system structure ".Water suction when raining, water storage, infiltration, water purification, it is necessary to when by the water stored " release " and be subject to profit
With.
Sponge city is built, first has to reverse idea.Mainly set for storm-water system with " slow row's sustained release " and " store and avoid the peak hour "
Meter theory, not only avoids flood, but also effectively have collected rainwater.
Roof drain is to be located at the inlet that rain water on roof is entered storm sewer by gutter.Roof drain has flow straightening grid device,
Rain water on roof can be excluded rapidly, grid has rectified action, avoids the formation of excessive vortex, stablizes water level before bucket, reduces aeration,
It is rapid to exclude rain water on roof, snow-broth, and can effectively stop compared with bigger material.The rainwater that roof drain is collected enters storm sewer, flow to
In raintank, when the rainwater of raintank storage exceedes a certain liquid level, discharged through overflow pipe.
Gravity stream refers to rainwater in rain pipe, by the effect of gravity(The gradient)Flow forward, is generally not filled with flowing,
Draining when suitable amount of rainfall is smaller;Pressure current refers to by pressurizeing to rainwater, rainwater is formed the state flowing of quick flowing full,
It is adapted to use when amount of rainfall is larger.
In many cities in China, all there are rainwater to discharge the problem of not smooth, and specific Producing reason can be roughly divided into
The following aspects:
1. dirty block seriously is blocked on ground.When rainy season set, under the influence of compared with heavy showers, urban discharging pipeline is because caliber
Etc. reason so that drainage speed can not meet requirement, meanwhile, silt of the storm sewer inner clip band from ground, leaf and part
House refuse etc., cleaning and dredging to pipeline, which are safeguarded, brings very big difficulty.
2. storm sewer water outlet is obstructed.The rainwater in current China major part city, is discharged into nearby by storm sewer
The water bodys such as river.But much it is located at the city of plains region, because being restricted be subject to position landform, water outlet, which uses, to be flooded
No formula so that the position of water outlet will be less than the water level of water body.In rainy season, water body water level generally goes up, and is subject to water body water level
Jacking, the water velocity inside storm sewer slow down, and cause the drainability of drainage pipeline and reduce.When rainy season set
There is ponding in low-lying land rapid lapse of time, have impact on the current of nearby residents.
3. lack necessary connection between urban rainwater pipeline.Current storm sewer can generally build up several independent drainings
System carries out rainwater exclusion, is not connected mutually between each drainage system.But in actual drainage procedure, because rain pipe
The time that the charge for remittance of each system in road is how many, catchments has it uncertain, so can not possibly be at the same time in flood season rainwater peak flow
Occur, the drainability of each drainage system is also just different.
PHC pile piles, i.e. PHC piles.It is to use pre-tensioned prestressing centrifugal molding process, and passes through
10 atmospheric pressure, 1800 DEG C or so of steam curing, are made a kind of hollow cylinder shape concrete prefabricated element, and standard knot is a length of
10m, diameter is from 300mm~800mm, strength grade of concrete >=C80.PHC pile piles are held jointly by collateral resistance and end resistance
By upper load, and it is adaptable to the big geological conditions of supporting course fluctuations, therefore adaptation region is wide, building type is more.
In heavy construction, the usage amount of PHC pile piles is very big, and the usage amount of single project is usually up to hundreds if not thousands of roots, pile foundation
Depth is up to tens of rice.For protection stake lower end and back cover, prevent from preventing stake from shifting into soil in pipe, effectively improve the list of pile pile
Pile bearing capacity, when PHC pile piles carry out pressing pile construction, often installs pile top at the termination position of PHC pile piles.Pile top have it is cross and
Tip type etc..Superstructure load friction is undertaken for using the frictional force between end-resistance and pile body side and soil jointly
PHC pile piles, its pile top is still in Soft Soil Layer.

In the course of work of the present invention, it is not necessary to which consumption electric power drives water pump, realizes that zero energy consumption of rainwater is pressurizeed, makes rainwater
Fluidised form in the duct is to be increased full of stream, the inflow-rate of water turbine of unit interval interior conduit from rheology is not filled with, and significantly improves rain pipe
Conveyance capacity in heavy rain, avoids Super High or skyscraper excess surface water.Simultaneously because using small one and large one two pistons,
Discharge pressure enough in the case of, only use smaller size smaller sewage(Rainwater)Discharge larger volume rainwater can be reached
Effect, save the sewage in high water tank(Rainwater), the water in the high water tank of unit volume is pressurizeed more volumes
Rainwater.The discharge that so rainwater just can be more efficiently.
Such as:A certain high-rise building, its high water tank have the static pressure of 100m water columns, first piston plate 37 and second
The area ratio of piston plate 39 is 1:5, pressure=pressure * areas, in the case where static pressure is certain, first piston formula water tank 36
It is 5 with the pressure ratio in second piston formula water tank 38:1, when ignoring the pressure loss, the pressure in second piston formula water tank 38
About 20m water columns.If the pressure head in second piston formula water tank 38 is larger, there is the problem of impact is produced to neighbouring well lid
When, a drainpipe can be individually set up, the downstream place that rainwater is led to remotely is discharged, so as to not influence neighbouring rainwater
Discharge.
Hydraulic pressure is adjusted:Second electric control valve 31 can be adjusted according to the pressure at 39 right side rainwater extrusion end of second piston plate
Save flow and pressure that waste water enters piston.By adjust waste water into piston flow and pressure come adjust rainwater extrude stream
Amount and pressure, avoid when municipal 32 heavy rain of rain pipe is formed full of stream, rainwater superpressure enters municipal Storm Sewer Network.Avoid the formation of
Anti- excessive phenomenon.
The degree of filling of municipal Storm Sewer Network 32 and the pressure of pressurization rainwater entrance can pass through 33 He of liquid level sensor respectively
Second hydraulic pressure sensor 42 of pressurization rainwater entrance is monitored, and in the case of non-extreme heavy rain, municipal Storm Sewer Network 32 is not filled
In the case of full, even if rainwater superpressure sprays into municipal rain pipe, rainwater will not be caused to return excessive phenomenon.But when municipal Storm Sewer Network
In the case of 32 be full of, the pressure in the pressure ratio municipal administration Storm Sewer Network for the pressurization rainwater for spraying into municipal Storm Sewer Network 32 is high
Numerical value not should be greater than buried depth at the top of pipe network, otherwise may result in rainwater return it is excessive.So piston rainwater extrudes cavity and pressurization rainwater
Entrance is respectively equipped with the 3rd hydraulic pressure sensor 43, and pressure signal is fed back to controller 4, and municipal rain pipe is discharged into pressurization
Under the operating mode in road, controller 4 is controlled the second electric control valve 31 according to default program.
