Description
Technical field
The utility model is related to a kind of adjustable plastic concrete mixed structures of interception ratio intelligently to cut dirty well, belong to draining
Engineering field, the more particularly to sewage of confluence of rainwater and sewage pipeline retain structures.
Background technology
Urban Drainage System is divided into separate system and combined system.Separate system is that two independent systems are respectively adopted in rainwater and sewage
System is discharged, and rainwater is discharged into the water bodys such as river, and sewage is discharged into after sewage plant is handled by pipeline collection and is discharged into water body again.Interflow
System is that rainwater and sewage are collected using a system, and sewage is carried out before being discharged into water body and is shut off, and sewage drains into dirt by cutting dirty pipe
Water factory is handled, rainy day rainwater and sewage interflow, is directly discharged into water body beyond the flow that dirty pipe designs holding filth capacity is cut, collecting fitting is made
Valence is relatively low.Many cities are using the run-off system of combined system the problems such as first stage of construction is due to population, fund, and some is even
Shut off without sewage and is directly discharged into water body.First stage of construction is less serious to the pollution of water body since population is few, does not also obtain weight
Depending on.With the development of economy, a large amount of sewage is directly discharged into water body and pollutes, people turn back again carry out environment control
Reason.Section dirty pipe that either primary construction is just provided with the combined drainage system for cutting dirty pipe or later stage environmental improvement increases newly
Road is directed to a kind of drainage structures --- and sewage intercepting chamber also referred to as cuts dirty well and hereinafter referred to as cuts dirty well.
The dirty well that cuts of the prior art mainly has downflow weir formula, great-jump-forward, flashboard type etc..Downflow weir formula cuts dirty well and belongs to water blocking
Type is that downflow weir is arranged in cutting dirty well, usually there was only sewage in collecting fitting, and flow is smaller, is no more than the height of downflow weir, dirty
Water, which is shut off by downflow weir blocking to a section dirty pipe, to be arranged to sewage plant, and rainy day sewage is mixed into rainwater cuts a dirty well, works as confluence of rainwater and sewage
Flow increases, and when water level is more than the height of downflow weir, interflow water is overflowed from downflow weir is discharged into water body by cutting the delivery pipe of dirty well,
Cut at this time in dirty pipe be filled with interflow water drain into sewage plant.Some cut dirty pipe and are not immediately discharged to sewage plant, but are connected to city
Sewage pipe collects drains into sewage plant again, the pure sewage of the water inlet not just separate sewage system of such sewage treatment plant, also
It is mixed into a large amount of confluence of rainwater and sewage water, since excessive interflow water and sewage are mixed into sewage plant, into the water quality of sewage plant
And water, it is excessive in the difference of fine day and rainy day, very big difficulty is brought to sewage plant operation, while water inlet has exceeded sewage plant
Processing capacity, sewage plant can only handle a part of sewage, and what it is beyond processing capacity is usually to be directly discharged into water body, is caused to environment
Prodigious influence.Great-jump-forward section dirt well belongs to waterpower type, and the water inlet collecting fitting of section dirty well is managed higher than a section dirt and a delivery pipe, in utilization
Trip collecting fitting water changes the flow curvilinear motion principle to be formed and cuts dirt, cuts between dirty pipe and delivery pipe and weir plate, collecting fitting is arranged
When inflow is less than design combined closure system, intercepting sewer is fallen into water inlet, and when collecting fitting inflow is more than that design cuts dirty flow, water inlet is jumped
Jump, which crosses weir plate and enters delivery pipe, is discharged into water body.Great-jump-forward, which cuts dirty well, to be discharged into water body by a large amount of interflow water, but still has one
Branch, which falls into weir plate to flow into, cuts dirty pipe.Great-jump-forward cuts the collecting fitting that dirty well requires outlet drain pipe to be less than import, ability of intaking
Jump crosses weir plate and enters delivery pipe, but section dirty well that transformation is added on existing collecting fitting, the collecting fitting and outlet drain of import
Pipe can not be reduced in same absolute altitude since downstream line is discharged into the limitation of water body absolute altitude, thus cut dirt in existing collecting fitting
In improvement project, great-jump-forward cuts the inadaptable of dirty well.Flashboard type cuts dirty well and belongs to mechanical, and the rainy day is by manually or electrically closing
Flashboard is closed, interflow water, which does not enter, to be cut dirty pipe and be all discharged into water body, and sewage plant does not have the interflow water of excess to enter, and will not cause to locate
Reason ability excess load.But flashboard type cuts dirty well and numerous dirty wells that cuts along section dirty pipe is needed to use manual control, operates
It is inconvenient, it is in the majority still to cut dirty well with downflow weir formula and great-jump-forward in the prior art.
Calculating for cutting dirty well mainly reasonably determines used interception ration 0, according ton 0It determines to cut dirty pipe
Design discharge and delivery pipe are discharged into the vent flow of water body.It is contaminated to make water body lack from the angle of environmental protection, it should use
Larger interception ratio, but economically, interception ration 0It is excessive, it can greatly increase and cut dirty pipe, Boosting pumping station and dirt
The cost of water factory, while the water quality and water of sewage plant are caused entry into, it is excessive in the difference of fine day and rainy day, it is run to sewage plant
Bring very big difficulty.To make the cost of entire collecting fitting drainage system rationally and being convenient for operational management, excessive cut should not be used
Flow multiplen 0.Current edition《Code for design of outdoor sewerage engineering》GB50014-2006 regulations, interception ration 0It should be according to the water of dry flow sewage
The factors such as matter, water, environmental carrying capacity, the hydrology, weather, economy and the drainage size of discharge water body are computed determination, shut off
Multiplen 0Preferably use 1~5.The prior art cuts dirty well interception ration 0It is typically fixed, it is economical with the increase of population
Development, sewage quantity can increase therewith, high when the more former design of wastewater level when fine day in collecting fitting, after the rainy day is mixed into rainwater, overflow
The water for crossing downflow weir or the weir plate that jumps is constant, is not intrinsic interception ratio water to the rain sewage mixing water of discharge into water
Amount cuts the interception ratio of dirty welln 0It will accordingly reduce, that is, sewage content increases in the water discharged, and rainwater content reduces, unfavorable
In environmental protection.
The dirty well majority that cuts of the prior art is according to collecting fitting and to cut the specific location of dirty pipe and be designed, using brick or
Person's concreting, most of in Practical Project is to use brickwork construction, brick to have construction letter relative to concrete structure
Just, the advantages that short time limit.But the building by laying bricks or stones of brick drainage inspection well requires very high, and puzzle joint mortar answers full, well inner waterproofing mortar
Plastering wants closely knit.Closed-water test is carried out before drainage pipeline backfill, examines the airtight performance of pipeline.Closed-water test requires band well to try
It tests, i.e., pipeline is together with inspection shaft closed-water test.Often there is inspection shaft in practice of construction, to build brickwork joint by laying bricks or stones not tight, especially
Be it is more difficult between pipeline and inspection shaft build by laying bricks or stones, the hidden danger of quality such as plastering leakiness in well.The inspection shaft of concrete cast in situs
Leakiness of vibrating also will appear drainage.
