Specific embodiment

As shown in Figure 1, a kind of rainwater after-treatment system, including level-one reservoir 1,1 one end of level-one reservoir pass through water inlet Pipe 2 is connected to municipal drainage network management, and 1 other end of level-one reservoir is connected to by box culvert 3 with pump pond 4.Pass through level-one water storage Pond 1, pump pond 4 will converge early period by collection, filtered rainwater.By the way that level-one reservoir 1 is arranged in pump 4 front end of pond, Be conducive to reduce water pressure.

Pump 4 one end of pond is equipped with pumping plant unit 5, and pumping plant unit 5 is drawn by more isocons 6, and isocon 6 passes through coagulation It is connect after native valve well 7 with general pipeline 8, general pipeline 8 is connect with stilling pond 9, and stilling pond 9 passes through the first pipe of concrete 10, inspection shaft 11 And second pipe of concrete 12 be passed into rivers.

Here isocon 6 is using the penstock of DN700mm, and general pipeline 14 is using DN900 penstock, the first concrete Pipe 10, the second pipe of concrete 12 use the international I grades of armored concrete flat tubes of DN1500mm.

Penstock uses Q235 carbon steel tubing, and penstock interface uses welding junction, and armored concrete flat tube connects Degree of lip-rounding formula smears band interface using ferro-cement.

Water, by pump pond 4, is drawn and is shunted using pumping plant unit 5 after reservoir 1 collects by rainwater, Jing Duogen isocon 6, general pipeline 8 enters stilling pond 9, is most discharged into the Changjiang river through the first pipe of concrete 10, inspection shaft 11 and the second pipe of concrete 12 afterwards.

By the way that inspection shaft 11 is arranged, can facilitate the later period occur blocking or other in the case of when slip into and repair, and the power that disappears Pond 15 can converge the water in isocon 6, then be discharged again through pipe of concrete, reduce and drain to isocon 6 itself Pressure requirements.

As shown in Fig. 2, the pump pond 4 includes pump pond ontology 13, pump 13 inner route clapboard of pond ontology is divided into the first compartment 14, the Two compartments 15, third compartment 16 and the 4th compartment 17.Wherein the first compartment 14 is connected by the inlet tube 18 and box culvert 3 of DN1500mm It is logical, be equipped with lifting valve 19 in the first compartment 14, lifting valve 19 includes square type electric flashboard 29, square type electric flashboard 2 with go out Pre-buried flashboard sliding rail frame is slidably matched at mouth 20, and 2 top of square type electric flashboard passes through wirerope 30 and CD1 type electric block 31 Connection.Square type electric flashboard 2 is promoted or reduced by starting CD1 type electric block 31 and realizes that rainwater flows into pump pond or barrier water Stream.

As shown in Fig. 2, 15 upper end of the second compartment is equipped with opening 21, anti-fishing formula grid decontamination is equipped in the second compartment 15 Machine 22.At installation initial stage, according to layout design advance reservation installation space apart from size hole size, loop wheel machine machine is then utilized Tool is lifted to pump pond.Anti- fishing 22 one end of formula grid sewage-removing machine is placed in 15 bottom of pond of the second compartment, and one end is stretched out outside opening 21.Pass through Motor driven flows into rubbish promotion to ground subsidiary in the rainwater in pump pond or more, easy cleaning, to avoid stifled to pump machine Plug.

Pump machine 23 is installed, pump machine 23 is pulled water out and drawn by isocon 6 in the 4th compartment 17.

By being divided into multiple compartments, on the one hand, partition can play certain supporting role, guarantee the stabilization in entire pump pond 4 Property, function division in addition can be carried out, facilitates and carries out garbage reclamation, pumping draining etc., reduces mutual influence.

As shown in figure 3, the isocon 6 is wrapped with impermeable structure 24, impermeable structure 24 is equipped at concrete valve well 7 The casing 25 being arranged in outside isocon 6 is included, reinforcing ring 26 is welded on the outside of casing 25, reinforcing ring 26 is embedded in concrete valve well 7 P8 high-strength concrete layer 27 is then arranged in interior and clamping between described sleeve pipe 25 and isocon 6.By the way that P8 high-strength concrete layer is arranged 27, it can be effectively prevent leak or infiltration, guarantee that installation quality is up to standard.

First compartment, 14 top and 21 tops of opening are embedded with reticulate pattern steel deck-plate 32.By being embedded with reticulate pattern steel deck-plate 32, it is sealed building the later period by openings of sizes.It can facilitate to tilt reticulate pattern steel deck-plate when there is situation in this way and carry out clearly Reason maintenance, is reduced to whole influence.
