Description
Technical field
The utility model belongs to cities and towns drainage system, environmental protection technical field, is specifically related to the manhole of drainage system.
Background technology
Manhole is basic, the crucial ancillary structure of in the drainage system of cities and towns, mainly be arranged on sewer direction turning point, change place of the sewer gradient, pipe duct section, basis, interface change place, pipe duct intersection, the straight line pipe duct every certain distance and special purpose (locating) as drop, hold back, overflow etc., be used to realize the connection between the sewer, and make things convenient for the pipe duct maintenance.
At present, draining field, cities and towns mainly contains combined system and two kinds of main drainage system forms of segregation system, and the former discharges rainwater and town sewage in same pipe duct, and the latter adopts two pipe duct systems to carry respectively rainwater and town sewage and discharges.In separated drainage system, manhole is respectively applied for and connects rainwater pipe duct (for rainwater pipe duct system) and sewage pipe duct (for soil pipe canal system system), and in combined drainage system, manhole is used for connecting the interflow pipe duct, but no matter for any form, manhole all adopts form of single sheet.Manhole in above-mentioned two kinds of drainage systems exists certain defective and deficiency:
(1) for the shutoff type combined drainage system, rainwater and sewage can mix mutually in manhole, when particularly rainfall exceeds the interception capacity of downstream pipe duct, unnecessary rain, dirty interflow water need overflow, owing to contain the pollutant of various ways such as a large amount of organic matters, suspension in the overflow water, can cause more serious pollution to receiving water body, and when flowing line from the river course, lake, pond waters have long apart from the time, the overflow pipe duct is also comparatively inconvenience on laying, and also there is the problem of addressing difficulty in manhole.
(2) for separated drainage system, rain, the dirty mixing generally can not appear in manhole, but on the one hand, manhole quantity ratio is held back the formula combined drainage system and will be increased considerably, can increase considerably the investment of manhole, and take a large amount of spaces, street, bring greater inconvenience for the setting of other kinds pipeline well, the cities and towns limitation particularly comparatively narrow for the street, that the underground space is comparatively limited is bigger, in regular maintenance for the also corresponding increase of the influence of traffic; On the other hand, usually can occur the phenomenon of rain, sewage hybrid junction in practice, cause the segregation system manhole in fact to become two interflow manholes.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the utility model proposes a kind of rainwater, sewage compound double-layer drainage manhole, the rainwater pipe duct is inserted on the manhole upper strata, the sewage pipe duct inserts in lower floor, realize that single manhole can admit rainwater and sewage simultaneously, and, reduce space hold and construction investment, and realize the normal function of routine inspection well by the separately connection in manhole of rainwater pipe duct, sewage pipe duct.
The technical solution of the utility model is as follows:
A kind of rainwater, sewage compound double-layer drainage manhole, this manhole has well body and well lid, in the middle of the well body, be provided with horizontal able to turn on or off intermediate active interlayer, the intermediate active interlayer is divided into manhole two-layer up and down, lower floor is used to connect the sewage pipe duct and allows sewage to pass through, the upper strata is used to connect the rainwater pipe duct and allows rainwater to pass through. like this by a manhole, surface runoff and sewage layering are passed through in the time of both can having realized surface runoff, can there be maintenance to open movable interlayer when needing and make the staff enter lower floor again. simultaneously, the intermediate active interlayer is provided with ventilating pipe, be communicated with the two-layer up and down of manhole, guarantee the normal ventilation and the safe operation of lower floor.
For able to turn on or off intermediate active interlayer, can adopt all-in-one-piece able to turn on or off formula structure, or adopt intermediate course main body and manhole are fixed, able to turn on or off activity is set on the intermediate course main body opens and closes the structure of cover plate form, the movable cover plate that opens and closes will guarantee that it has the big or small space that appearance service work personnel pass through.
Further, on the intermediate active interlayer in described manhole the structure of damming can also be set, spill etc. when producing surface runoff, allow partially face diameter stream to realize damming of rain runoff just by damming into lower floor's manhole in the aperture to water at precipitation or road.The structure of damming can be set to the fixing circle of size or the form of bar hole/seam, also can be set to the form that the regulated quantity size is regulated with the rainfall runoff amount, be provided with one by the spring controlled blind patch that dams as the hole of damming in circle or bar shaped/sew on, at ordinary times with the low discharge rainfall runoff time, cover plate draws back certain angle by spring and forms the hole and allow rainfall runoff to dam into lower floor's manhole of damming, and in rainfall, cover plate increases with amount of rainfall in the well of upper strata, the depth of water increase effect of being stressed rotates and the hole dimension that dams is reduced gradually even closes, and reduce along with rainfall and be withdrawn into original opening gradually by spring in the later stage, enter lower floor's manhole in the time of can avoiding rainfall runoff excessive like this.
This manhole is compared with existing manhole, has the following advantages:
In same well, realize being connected of rainwater pipe duct and sewage pipe duct simultaneously, and further can realize damming of early-stage rainwater runoff, cut down the polluting effect of rain runoff just significantly, and compare with existing separated drainage system, can reduce the quantity of manhole, the cost of investment that reduces the sewer system and later stage operation and maintenance cost significantly, reduce to the space, street take, reduce complexity that all kinds of pipeline wells in intersection are provided with and operation maintenance influence to traffic, and compare with the formula combined drainage system of holding back and not produce overflow water and pollute.
