Description
Technical field
The utility model relates to a kind of Novel flow-stopping well.
Background technology
Existing municipal catchpit mostly is steel concrete catchpit, and adopts Gravity separate principle to be separated rain sewage, and manhole well lid adopts ductile cast iron manhole cover.Cast-in-situ steel reinforced concrete manhole intensity is C25 steel concrete, and its construction period is long, and difficulty is comparatively large, and complex process, heavy duty service has a big risk.Ductile cast iron manhole cover is Prefabricated, and quick construction is convenient.Gravity separate principle is when a large amount of rainwater enters catchpit, and part rainwater flows into sewage conduct simultaneously, increases sewage conduct load.Common ductile cast iron manhole cover is not high with the Connected degree on road surface, easily produces differential settlement, impact driving comfort level.Under the situation of current structure economy type, environment-friendly type society, above construction material and technology cannot satisfy the demands, therefore apply for adjustable catchpit.
Utility model content
For the technical problem solved, the utility model object is to provide a kind of Novel flow-stopping well, and when amount of rainfall is larger, close sewage conduct, water (comprising a large amount of rainwater and a small amount of sewage) flows out from storm sewer, alleviates sewage conduct load.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Novel flow-stopping well, comprise well lid, pit shaft, well room and cover plate, well indoor are respectively equipped with interflow pipeline, storm sewer and sewage conduct, place, described sewage conduct delivery port bottom height is lower than place, pipeline bottom, interflow height, place, described storm sewer delivery port bottom height is between sewage conduct delivery port bottom height and place, pipeline bottom, interflow height, it is characterized in that, described sewage conduct is provided with by floating drum, the shutoff valve of watertight shutter and sealing copper ring composition, when the water yield is less, sewage conduct water outlet is in opening, water enters sewage network, when rainfall is larger, floating drum drives watertight shutter to rotate under buoyancy, close sewage outlet, water enters storm sewer.
Wherein, described well lid is adjustable spheroidal graphite iron well lid.
Wherein, pit shaft is vertical extruded by concrete modular with the borehole wall.
Wherein, described catchpit is three-way shutoff well.
Compared with prior art, the utility model has following beneficial effect:
(1) by using shutoff valve, when without the need to external plant equipment and Energy control, realizing damming truly, alleviating sewage conduct load;
(2) pit shaft and well room adopt concrete modular extruded, and improve catchpit construction technology, construction technology is simple and convenient, flexibly fast, shortens construction period, reduce difficulty of construction;
(3) common ductile cast iron manhole cover is improved to adjustable spheroidal graphite iron well lid, solves the problem of road-ability.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of adjustable catchpit;
Fig. 2 is shutoff valve opening figure;
Fig. 3 is shutoff valve closed condition figure.
Main Reference symbol description
10 well lid 11 pit shaft 12 well room 14 cover plate 15 shutoff valves 16 collaborate pipeline water inlet
17 sewage conduct delivery port 18 storm sewer delivery port 151 floating drum 152 watertight shutter 153 sealing copper rings.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 ~ Fig. 3, for the utility model catchpit sectional drawing and choke valve are opened and closed condition schematic diagram.Novel flow-stopping well, in the utility model, for three-way shutoff well, comprise well lid 10, pit shaft 11, well room 12 and cover plate 14, interflow pipeline is respectively equipped with in well room 12, storm sewer and sewage conduct, place, sewage conduct delivery port 17 bottom height is lower than place, pipeline 16 bottom, interflow height, place, storm sewer delivery port 18 bottom height is between sewage conduct delivery port 17 bottom height and place, pipeline water inlet 16 bottom, interflow height, , sewage conduct is provided with by floating drum 151, the shutoff valve that watertight shutter 152 and sealing copper ring 153 form, when the water yield is less, sewage conduct delivery port 17 is in opening, because sewage conduct delivery port 17 bottom height is lower than storm sewer delivery port 18 bottom height, rainwater or sewage enter sewage network by this delivery port 17, discharge through sewage conduct, when a large amount of rainwater enters in catchpit, water level in catchpit is in propradation, along with the rising of water level, floating drum 151 rises under buoyancy, drive watertight shutter 152 to rotate, sewage outlet is closed, make rainwater flow into storm sewer 18, thus realize the object of primary rainwater closure, avoid sewage conduct load.
As a preferred embodiment, the well lid 10 of catchpit selects adjustable spheroidal graphite iron well lid, the walling crib of well lid 10 with road bituminous layers in conjunction with as a whole, change the force-bearing situation of walling crib, travel load by more than 80% directly to be absorbed by road surface by walling crib, walling crib can be elevated along with road surface, improves the comfortableness of driving.
As another preferred embodiment, pit shaft and the borehole wall adopt concrete modular to make, and this concrete modular is by raw material high frequency tampings according to a certain ratio such as sand, stone, cement, flyash, vertically extruded.The four sides up and down of module is provided with tongue and groove structure, and composition builds rear formation chain lock by laying bricks or stones.Module is hollow structure, and combination is built rear form longitudinal hole hole by laying bricks or stones and passed through mutually, the reticulated cell that transverse holes hole communicates, form cast-in-situ concrete net structure after core note.
Here for rectangle 90 ° of three-way shutoff wells common in town road, working procedure is described:
Preparation → concrete cushion → well room builds by laying bricks or stones → and shutoff valve installs → marks time installation → cover plate installation → pit shaft and build → wipe one's face jointing → walling crib by laying bricks or stones and well lid is installed.
The technical solution of the utility model can shorten construction period greatly, enhances productivity, and reduces construction technology; Realization retains, and alleviates sewage conduct live load; Promote road aesthetic property, comfort.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
