Description
Technical field
The invention belongs to municipal drainage technical fields, and in particular to double-layer drainage guard system.
Background technique
Currently, domestic run-off system mainly has combined system and two kinds of separate system.Combined system be same pipe duct system collect,
The drainage pattern of sewage and rainwater is conveyed, separate system is the draining for collecting, conveying sewage and rainwater respectively with different pipe duct systems
Mode.Since there are waters to fluctuate outside to sewage plant influence on system operation, rainy season pollution load of overflow and dry season siltation foul smell for combined flow system
The problems such as excessive, therefore code requirement, in addition to arid area, newly-built drainage system should be using separate system and to existing combined system
Drainage system should implement rain sewage diversion transformation.
Patent disclosed above or it need to largely be arranged that inspection shaft, the scale of construction are larger, maintenance is difficult and cut-off equipment influences overcurrent
Ability and easy failure;Buried depth is deep, construction backfill requires height, and has a single function, and can not achieve the initial rainwater that shuts off
Effect.And sewer is that all closed pipeline or the double-deck channel, repair and maintenance are difficult；Since inflow-rate of water turbine, ventilation and maintenance are wanted
Ask pipe duct size big.In addition it needing individually separately to seek the inlet for stom water that rainwater on road surface is collected in path space setting, structure is complicated for storm-water system,
Overhaul management is inconvenient, and system buried depth is relatively deep to be required to correspondingly increase to construction working face, this requires that town road needs enough
Width implement, also therefore be limited in the insufficient region of the widths of roadway such as the street lane of drainage system upstream separate system transformation.On
State it is insufficient still have be worth improved place.
Summary of the invention
It is an object of the present invention to overcome the above deficiencies, so that double-layer drainage guard system is provided, it can be by rain sewage
Pipe duct lays with position and realizes the initial rainwater that shuts off, and reaches that the small scale of construction, variable capacity, buried depth are shallow, occupy little space, invest economic and convenient
In the use purpose of repair and maintenance.
According to technical solution provided by the invention, double-layer drainage guard system includes pipe duct main body, and waist is set in pipe duct main body
There is a membrane support, elastic baffle is connected by connector in membrane support, it is characterized in that: elastic baffle is by pipe duct main body internal channel
It is divided into upper layer and lower layer, upper layer is rain water channel, and lower layer is sewage routeway;Elastic baffle is equipped with cutoff hole, cutoff hole underface
Limit valve equipped with shutting off, it is big in lower layer's sewage quantity and when oilysewage surface being caused to rise, ball-cock assembly is taken up to block by the buoyancy of sewage and be cut
Discharge orifice;Cover board is equipped at pipe duct main body upper end opening, cover board covers the opening of pipe duct main body, is uniformly provided with multiple let out on cover board
Water hole.
Further, pipe duct main body uses rectangle, oval or shape of a hoof cross-sectional shape.
Further, connector uses snail or clip.
Further, elastic baffle can be using rubber, silica gel or the production of elastoplastic elastomeric material.
Further, shut off and limit valve using ball-cock assembly.
Further, the shape of cutoff hole can be round, ellipse or rectangle.
Compared with the prior art the present invention has the advantage that
The invention has the advantages of simple structure, compactness and reasonable structure, the initial rainwater that shuts off can be laid and realized with position by rain sewage pipe duct, reach
The scale of construction is small, variable capacity, buried depth is shallow, occupies little space, is with low investment, the use purpose of easy access maintenance.

Specific embodiment
The present invention will be further described in conjunction with the embodiment in attached drawing below:
As shown in Fig. 12, the invention mainly comprises pipe duct main body 1, waist is equipped with membrane support 2, partition branch in pipe duct main body 1
Elastic baffle 3 is connected by connector in support 2,1 internal channel of pipe duct main body is divided into upper layer and lower layer by elastic baffle 3, and upper layer is rain
Aquaporin-5, for arranging rainwater;Lower layer is sewage routeway 4, is used for sewerage.
Elastic baffle 3 is equipped with cutoff hole 8, and cutoff hole 8, which is arranged right below to shut off, limits valve 7.Shut off and limits valve 7 using floating
Ball valve, it is big in lower layer's sewage quantity and when oilysewage surface being caused to rise, ball-cock assembly is taken up by the buoyancy of sewage blocks cutoff hole 8, prevents
Sewage enters in upper layer rain water channel 5.
Cover board 6 is equipped at 1 upper end opening of pipe duct main body, cover board 6 covers the opening of pipe duct main body 1.On the cover board 6
Even to be equipped with multiple drain holes 9, rainwater is flowed into pipe duct main body 1 by drain hole 9.
The working principle of the invention is: pipe duct main body is separated into bilevel sewage routeway to elastic baffle and rainwater leads to
Road.Sewage is excluded by lower layer's sewage routeway, and rainwater is excluded by upper layer rain water channel.It is arranged on cover board above pipe duct main body and sluices
Hole, rainwater enters rain water channel by drain hole when raining, a small amount of seriously polluted initial rainwater by rain water channel bottom bullet
Cutoff hole on property partition enters sewage routeway.With the continuation of rainfall, the rainwater into rain water channel increases, into lower layer's dirt
The retention rainwater of aquaporin increases, and lower layer's sewage routeway water surface curve rises, and is arranged in shutting off below elastic baffle and limits valve and exist
Rise under the action of buoyancy and block cutoff hole, stop shutting off, rain water channel and sewage routeway are completely isolated, and two sets of formation is respectively only
Vertical separate sewage system.As rainfall is continuously increased, the amount of rainfall into rain water channel is gradually increased, and elastic baffle is not
Break gradually sagging under increased rainwater gravity, to be continuously increased rain water channel flow section, increases rain water channel overcurrent
Ability can quickly exclude rainwater on road surface.Elastic baffle resets after rainfall, and system is restored.When needing to overhaul, open cover board and
Elastic baffle can carry out dredging maintenance to upper and lower level rain water channel and sewage routeway.
