Traditional filter well and road drainage port are combined by patent of the present invention, and set up pressue device, make road drainage well can adapt to the dewatering needs of different rainfall.
(2) technical scheme
The pressure water seepage road drainage shaft that patent of the present invention relates to, is made up of natural drainage systems, natural infiltration system, pressure infiltration system.Wherein natural drainage systems are similar with traditional road discharge outlet, are made up of leaf grating for down pipe, the waterproof borehole wall, drain pipe；Naturally infiltration system is similar with tradition filter well, is made up of the permeable borehole wall, husky base drainage layer, gravel layer；Pressure infiltration system is made up of motor, water pump, filter, level sensor, infiltration water pipe, utilizes water pump to provide pressure, is forced by water around press-in infiltration water pipe and in the soil of end.
(3) beneficial effect
The pressure water seepage road drainage shaft that patent of the present invention relates to can automatically select drainage pattern according to rainfall.If rainfall is less, then by natural infiltration mode, rainwater is discharged to underground, the most naturally the work of infiltration system；If rainfall is slightly larger, rainwater did not had drain pipe port, then removed by Water in Rainwater Drainage by water pipe, the most naturally infiltration system and natural drainage systems work；If rainfall is big again, will not have the level sensor of excess pressure infiltration system, start motor switch, drive pump working, now three digest journals works together.
Heavy rain was fallen over a large area in Guangzhou City, in inner city, owing to water logging causes traffic jam on May 7th, 2010, part retail shop, parking lot are flooded, it is impacted that the whole city has 35 underground parkings, and 1400 multiple stage vehicles meet with water logging, and extra torrential rain causes about 5.44 hundred million yuan of economic losses to In Guangzhou Area.
In JIUYUE, 2010 is attacked by extra torrential rain 20, causes 109.86 ten thousand people disaster-stricken, dead 33 people, missing 42 people, direct economic loss 20.08 hundred million yuan.
On July 21st, 2012, extra torrential rain attacked Beijing, whole city population suffered from disaster 160.2 ten thousand people, and victim's total number of persons reaches 79 people, because calamity causes economic loss 116.40 hundred million yuan.
Similar incidents are the most of common occurrence, emerge in an endless stream, if using pressure water seepage road drainage shaft at large-and-medium size cities main roads, realize the mode draining that natural drainage, naturally infiltration combine with pressure infiltration, not only can be greatly improved drainability, groundwater level can also be effectively improved, prevent road collapsion and damage, inclined building that surface subsidence causes and collapse.Meanwhile, groundwater level improves, it is possible to makes green plants root system preferably absorb moisture, promotees its normal growth.
