Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described further.

Fig. 1-8 reference is: the gutter 1 that catchments, gap cover plate 2, desilting well 3, desilting manhole cover plate 4, collecting pipe 5, section dirt Basket 6, circle ooze water tank 7, overflow pipe 8, square ooze water tank 9, municipal administration rain pipe 10, municipal administration catch-basin 11, particle diameter 15～ Band 14, bicycle lane 15, footpath 16 and Tree Planting Earthdrill 17, wherein municipal administration are divided in 25mm metalling 12, car lane 13, side Rain pipe 10 is present situation pumping equipment with municipal administration catch-basin 11, and municipal administration rain pipe 10 is connected on the bottom of municipal administration catch-basin 11.

Sponge engineering system based on existing urban road Yu drainage condition, including the gutter 1 that catchments, gap cover plate 2, desilting Well 3, desilting manhole cover plate 4, collecting pipe 5, cut dirty basket 6, circle oozes water tank 7, overflow pipe 8 and square ooze water tank 9.

As shown in Figure 1-2, the gutter 1 that catchments is arranged on outside car lane 13 along at the flat tooth of road and at bicycle lane 15 And between footpath 16 at the flat tooth of road, cover gap cover plate 2 on gutter 1 catchmenting；Along catchmenting, gutter 1 sets every five to six meters Putting desilting well 3, in order to precipitate early-stage rainwater, cover desilting manhole cover plate 4 above desilting well 3, desilting manhole cover plate 4 is daily permissible Open and desilting well 3 and circle are oozed water tank 7, square ooze water tank 9, carry out desilting, maintenance.Divide in side band 14 existing arbors it Between bury circle underground and ooze water tank 7, circle is oozed water tank 7 and is arranged with desilting well 3 one_to_one corresponding, facilitates circle to ooze the inspection of water tank 7 Repair and clear up.Between the existing arbor of footpath 16, bury the square water tank 9 that oozes underground, square ooze water tank 9 and desilting well 3 one a pair Should arrange, facilitate the square maintenance oozing water tank 9 and cleaning.Gutter 1 and the circle of catchmenting ooze water tank 7, square ooze water tank 9 it Between connected by oblique collecting pipe 5 respectively, be provided with the collecting pipe 5 mouthfuls of desilting well 3 joint and cut a dirty basket 6.

Rainwater in car lane 13, bicycle lane 15 or footpath 16 is converged by gap cover plate 2 through road surface horizontal wall inscription Enter to catchment gutter 1, after the precipitation of desilting well 3 and the filtration of the dirty basket 6 of collecting pipe 5 mouthfuls section, imports circle via collecting pipe 5 and oozes Water tank 7, square ooze in water tank 9, and then directly penetrate into side and divide in band and footpath shade tree Soil Surrounding, play irrigation Afforestation vegetation and the effect of recharging groundwater.Meeting the extra torrential rain beyond 30 years standards, too much rainwater can be caused by overflow pipe Municipal administration storm sewer is discharged.

As shown in Fig. 3 (a), gap cover plate 2 is concrete material, and gap cover plate 2 is rectangle cover plate, gap cover plate 2 liang It is 20mm that minor face has the degree of depth respectively, the groove of a length of 200mm, when adjacent two pieces of gap cover plates 2 splice, and adjacent slits lid The groove docking of plate 2 forms the prismatic gap that width is 40mm, and rainwater imports the gutter 1 that catchments, prismatic gap by prismatic gap Coordinate desilting manhole cover plate 4 hole, discharge area more than 30 years storm recurrence period time rainwater discharge required for discharge area.

As shown in Fig. 3 (b), the gutter 1 that catchments is for concrete material, and generally, urban road present situation road tooth width is 300mm, Concrete U-type ditch wall thickness is 50mm, and for existing road surface is not caused disturbance, therefore gutter 1 clear span of catchmenting takes 200mm,.

In the present invention, the gutter 1 that catchments be designed as outer diameter length be 900mm, width be 300mm, the degree of depth be the U-shaped of 350mm Ditch, catchment gutter 1 wall thickness 50mm, and meanwhile, gap cover plate 2 thickness is 120mm, and a length of 900mm, width are 300mm；In gap Two long limits of cover plate 2 all have 50mm width trough with straight angle, directly can be placed in by gap cover plate 2 and catchment on gutter 1 ditch body during construction. The gutter 1 that catchments is arranged along flat tooth outside car lane, and ditch body longitudinal lap joint uses tongue and groove design, bottom the gutter 1 that catchments longitudinally one Side evagination 40mm, opposite side indent 40mm, form tongue and groove, during construction, adjacent splicing between gutter 1 of catchmenting is convenient and has very well Seal.

Desilting well 3 is concrete material, and desilting well 3 degree of depth is 650mm, width is 300mm, a length of 900, wall thickness is 50mm, desilting well 3 is connected with the gutter 1 that catchments, at desilting well 3 overlying desilting manhole cover plate 4.Desilting manhole cover plate 4 is concrete material, Thickness is 120mm, a length of 900mm, width are 300mm, has three rows five and indulge on desilting manhole cover plate 4, totally ten five diameters The circular hole of 50mm, both can collect rainwater, also designate the position of desilting well 3, and facilitate desilting to overhaul.

Collecting pipe 5 is internal diameter 100mm plastic tube, connects desilting well 3 and oozes water tank 7 with circle or be connected desilting well 3 and side Shape oozes water tank 9, and collecting pipe 5 is apart from desilting well 3 shaft bottom 200mm.

Circle oozes water tank 7 or the square water tank 9 that oozes is concrete material, and it is 1200mm that circle oozes water tank 7 external diameter, Being highly 1200mm, square water tank 9 external diameter length and width of oozing are 1200mm, a height of 1500mm, and volume all can meet sponge city The requirement of 90% annual flow overall control rate.Circle ooze water tank 7 or square ooze water tank 9 periphery parcel 50mm thickness grain is set Footpath 15～25mm metalling 12, it is possible to by storage rainwater naturally osmotic to soil.

As shown in Figure 4, overflow pipe 8 is caliber 40mm plastic tube, connects catchment gutter 1 and municipal administration rain pipe 10, overflow pipe 8 Distance set waterside ditch 1 20mm suitable for reading, circle oozes water tank 7 or square when oozing the full rainwater of water tank 9, and rainwater is in the gutter 1 that catchments Water level rises to overflow pipe 8 position, meets the extra torrential rain beyond 30 years standards, and circle oozes water tank 7 or the square water tank 9 that oozes stores After full rainwater, too much rainwater will cause municipal administration rain pipe 10 by overflow pipe 8 and discharge.

As it is shown in figure 5, receive collector 5 on desilting well 3, can be by filtering foreign in rainwater, foreign material are stayed and are cut in dirty basket 6, just The rainwater that step purifies imports circle by collecting pipe 5 and oozes water tank 7 or square ooze in water tank 9；On the one hand, as it is shown in fig. 7, Rainwater is imported by gap cover plate 2 through car lane 13 horizontal wall inscription and catchments gutter 1, then imports circle by collecting pipe 5 and ooze water tank 7 In, directly penetrate into side and divide in band 14 soil；On the other hand, rainwater passes through gap through bicycle lane 15 and footpath 16 horizontal wall inscription Cover plate 2 imports and catchments gutter 1, then is imported by collecting pipe 5 and square ooze in water tank 9, directly penetrates into footpath 16 shade tree In Soil Surrounding, play irrigation afforestation vegetation and the effect of recharging groundwater.

As shown in Fig. 6 (a), cut dirty basket 6 and be arranged on the collecting pipe 5 mouthfuls connected with the gutter 1 that catchments, can retain in rainwater Foreign material, make foreign material enter in desilting well；As shown in Fig. 6 (b), cutting dirty basket 6 is hemispherical PE Hanging Basket, cuts dirty basket 6 Hanging Basket mouth and sets ten Font is linked up with, and facilitates hook to take cleaning.
