During dry season, the sewage that is entered shunting well by interflow pipeline dams through cut-off groove 30, the space that the inwall that sewage flows into L-type plate, the second compartment wall 22 and flow control chamber 22a through cut-off groove 30 surrounds, through sewage transition conduit 32 (or sewage transition conduit 32 '), sewage branch pipeline 14, enter drainage 13 afterwards, finally by drainage 13, enter Wastewater Treatment Plant and process.
During rainfall, the first rain that is entered shunting well by interflow pipeline dams through cut-off groove 30, the space that the inwall that just rain flows into L-type plate, the second compartment wall 22 and flow control chamber 22a through cut-off groove 30 surrounds, through sewage transition conduit 32 (or sewage transition conduit 32 '), sewage branch pipeline 14, enter drainage 13 afterwards, finally by drainage 13, enter Wastewater Treatment Plant and process.
When rainfall surpasses the amount of damming of cut-off groove 30 originally, first rain flow through that cut-off groove 30 enters retaining chamber 4 by first rain import 40 and the passage chamber 22b that is communicated with it in, then enter the long line retaining pipeline 50,51 being communicated with retaining chamber 4 and passage chamber 22b, so that storage.In this process, increase and water level rise along with early-stage rainwater flow, the also corresponding increasing of flow in the space that the inwall of inflow L-type plate, the second compartment wall 22 and flow control chamber 22a surrounds, when surpassing the maximum inflow-rate of water turbine in the space that the inwall of L-type plate, the second compartment wall 22 and flow control chamber 22a surrounds, produce overflow, the water yield is overflowed from the side plate top of L shaped plate 31, enters flow control chamber 22a.
Water storage level in the 22b of passage chamber is during lower than water level in the 22a of flow control chamber, non-return flap valve 24a opens, rainwater admission passage chamber 22b in the 22a of flow control chamber, water storage level in the 22b of passage chamber is during higher than water level in the 22a of flow control chamber, non-return flap valve 24a closes, along with L-type plate, in the space that the inwall of the second compartment wall 22 and flow control chamber 22a surrounds, rainwater constantly overflows, in the 22a of flow control chamber, water level constantly rises, when water level surpasses after the circular keg float 35 of kickboard 33 bottoms, keg float 35 rises gradually under buoyancy, drive kickboard 33 to lift gradually, until by the port shutdown of sewage transition conduit 32 (or sewage transition conduit 32 '), make L-type plate, sewage in the space that the inwall of the second compartment wall 22 and flow control chamber 22a surrounds is no longer by sewage transition conduit 32 (or sewage transition conduit 32 '), sewage branch pipeline 14 enters drainage, thereby avoid excessive rainwater to enter the normal draining that drainage affects drainage.
After holding completely in retaining chamber 4, removable cover device is closed first rain import 40, by interflow pipeline, entering flow through cut-off groove 30,4 tops, retaining chamber of follow-up cleaner rainwater in shunting well is discharged by delivery port 20b, finally flow into river course, thereby avoided the early-stage rainwater of heavy contamination to flow into river course, river course has been polluted; Meanwhile, the impact while also having avoided interflow water flow of pipeline larger, drainage having been caused, has guaranteed the normal draining of drainage.
The rainfall later stage, displacement in the pipeline of interflow reduces, water level declines, the discharge reduction in the space that the inwall of cut-off groove 30 and L-type plate, the second compartment wall 22 and flow control chamber 22a of flowing through surrounds, behind the water level of the accommodation space top lower than sewage transition conduit 32 (or sewage transition conduit 32 ') port, circular keg float 35 drives kickboard 33 to decline gradually, finally makes kickboard 33 drop on baffle plate 34, recovers the sewage current floe condition of L shaped plate 31.
In retaining chamber 4 and water storage system 5, the first rain of savings is slowly retracted into drainage 13 through water-break system.Owing to entering the early-stage rainwater amount of long line retaining pipeline 50,51 and be greater than the water-break amount of water-break system, therefore, can the long line retaining pipeline being communicated with each shunting well be held full in the rainfall incipient stage, after the rain, again can be by early-stage rainwater amount from the slow drainage 13 that is retracted into of water-break system, in the situation that not affecting Wastewater Treatment Plant's operation, a large amount of early-stage rainwaters is processed.
Although above-mentioned, the utility model is described in detail; but the utility model is not limited to this; those skilled in the art can modify according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
