Detailed description of the invention
Embodiment
In FIG, provide a kind of stormwater overflow well with rain leakage function, include the overflow well 2 of upper end open, lower end closed, suitable for reading being provided with of described overflow well 2 cuts dirty basket 11, for collecting the foreign material such as leaf, improves the penetrating power of overflow well.Cut above dirty basket 11 and be provided with well lid 1, different weepage holes size, shape can be designed according to different situations.
The middle part of described overflow well 2 is provided with two drainage outlets 3, and drainage outlet 3 is 400mm with the height of bottom, and each drainage outlet 3 is respectively communicated with a rainwater arm 4, and unnecessary rainwater can be discharged to underground beyond overflow well 2 by arm.
Be positioned on overflow well 2 sidewall below drainage outlet 3 and be provided with four drain holes 5, the outside of drain hole 5 is enclosed with the permeable geotextiles 6 of internal layer, prevents silt from carrying out permeable formation.
Overflow well 2 bottom is provided with three rhones 9, and rhone 9 is all fixed with capillary penetrating drainage band 10.The water suction of capillary penetrating drainage band 10 utilizes " capillary force, siphon power, gravity, surface tension " self-assembling formation, filter, close, the function of draining, initiatively supersaturation water inspiration in soil is entered in drainage belt capillary hole slot, " capillary force " and " siphon power " produces negative pressure in capilar bore, impels drainage belt initiatively to absorb water draining.Because micropore is very little, silt can not be blocking microporous, and can prevent silt from entering the below of overflow well 2, is beneficial to the infiltration of permeable formation.
The bottom of overflow well 2 and bottom outer are provided with cobble 7, and cobble 7 lateral thickness is 200mm, and bottom thickness is 200mm, and cobble 7 outer wrap has outer permeable geotextiles 8.The permeable formation formed by cobble 7 can improve osmotic effect.
