Description
Technical field
The utility model relates to a kind of road surface facility, especially a kind of highway of collecting the road surface rainwater that filters.
Background technology
Stony desertification is a kind of extreme form of land deterioration; the southwest is that China suffers stony desertification serious area the most; it also is the key area that China's stony desertification is administered; lack of water, few soil and soil property are barren to be the main cause that causes the soil stony desertification; particularly arid makes stony desertification more serious; serious damage caused by a drought causes southwestern 5 provinces more than 6,130 ten thousand people disaster-stricken, at present, faces crisis in food after the total crop failure of part drought-hit area.This disaster also presents the situation that spreads and aggravate; in the face of so great natural calamity; we will consider to take effective way to sue and labour on the one hand; on the other hand; we more should consider the 21 century Development in China from long-range angle, fundamentally check spreading of ecological environment crisis.The natural rainwater of large scale collection also should become the new technology that we pay close attention to.The collection of rainwater now mainly is collecting naturally by river and bottom surface, but in the city, a large amount of rainwater can enter in the sewer pipe, and these rainwater are in case with after sanitary sewage mixes, not only collect difficulty, and the cost height of collecting, and need through a large amount of filtrations, also can't guarantee the water quality of the rainwater collected.
The utility model content
The purpose of this utility model is: a kind of highway of collecting the road surface rainwater that filters is provided, and it can collect the rainwater of highway pavement low-cost, expeditiously, can guarantee that the rainwater of collecting has higher water quality simultaneously, to overcome the deficiencies in the prior art.
The utility model is achieved in that and filters the highway of collecting the road surface rainwater, it comprises the highway bed course, on the highway bed course, be provided with impervious barrier, on impervious barrier, be provided with the highway surface layer, be provided with longitudinal drainage pipe along the highway direction in the side of highway bed course or impervious barrier, on the tube wall of longitudinal drainage pipe at interval be provided with collection hole, and on the longitudinal drainage pipe at interval be connected with transverse drain, one end of transverse drain is communicated with the longitudinal drainage pipe, and its other end extends outside the highway; Be provided with anti-filter lamination in the outside of longitudinal drainage pipe, be provided with pervious layer on anti-filter lamination, the structure of collecting gutter is formed on the top of pervious layer, is provided with replaceable primary filter piece on collecting gutter.
Anti-filter lamination and impervious barrier connect as one.
On the longitudinal drainage pipe of same position, be provided with 3 collection holes, between each collection hole on the equal angular tube wall that is distributed in the longitudinal drainage pipe.
Be provided with grid and anti-against current valve on the termination exposing of transverse drain.
The highway surface layer is the structure of infiltration surface layer.
Owing to adopted technique scheme, compared with prior art, the utility model adopts and in the side of highway the pipeline that can collect rainwater is set, earlier rainwater is carried out collecting behind the primary filter again, can effectively filter pollutants such as leaf, rubbish and suspended particulate, can obtain the rainwater of higher water quality, and collect with low cost, collection efficiency is high.The utility model is simple in structure, and cost of manufacture is cheap, and result of use is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is a longitudinal drainage pipe cross-sectional structure schematic diagram of the present utility model.
The specific embodiment
Embodiment of the present utility model: the structure of the highway of filtration collection road surface rainwater as shown in Figure 1, on soil, lay highway bed course 1, the infiltration layer 2 of setting up defences on highway bed course 1 upper berth, on impervious barrier 2, lay the highway surface layer 3 (rainwater on the highway surface layer 3 directly is penetrated in the pervious layer 8) of infiltration structure, dig out one zanjon along the highway direction in the side of highway bed course 1, longitudinal drainage pipe 4 is laid in this zanjon, on the tube wall of longitudinal drainage pipe 4 at interval be provided with collection hole 5, on the longitudinal drainage pipe 4 of same position, be provided with 3 collection holes 5, between each collection hole 5 on the equal angular tube wall that is distributed in longitudinal drainage pipe 4; And on longitudinal drainage pipe 4 at interval be connected with transverse drain 6, an end of transverse drain 6 is communicated with longitudinal drainage pipe 4, it is outer and expose that its other end extends highway, exposing of transverse drain 6 grid is installed on the termination and reached and prevent against current valve; In the outside of longitudinal drainage pipe 4 with the long-pending thing of the anti-filter (adhesive-bonded fabric that can adopt poly-vinegar class, nylon or polypropylene material such as geotextiles to make, its purpose is for can be permeable, but must intercept object such as silt again enters) be piled into anti-filter lamination 7, the anti-lamination 7 of filtering connects as one with impervious barrier 2; (pervious layer 8 can adopt pervious cement stabilization gravel filler to be provided with pervious layer 8 on anti-filter lamination 7, the coarse aggregate maximum particle diameter is not more than 40mm, the following fine particle content of particle diameter 4.5mm is no more than 16%, 2.36mm following fine particle content is no more than 6%, this is blocked for fear of band water gutter), structure into collecting gutter 9 is built at the top of pervious layer 8, (the primary filter piece adopts and place rubble in a permeable casing being provided with replaceable primary filter piece on the collecting gutter 9, make the leaf in the rainwater, rubbish and suspended solid etc. are adsorbed on the rubble of placement, when needing cleaning, just as casing takes out, pour out then rubble clear up get final product).
When raining, rainwater is introduced in the collecting gutter 9, pass through the primary filter of primary filter piece earlier, again after the filtration by pervious layer 8 and anti-filter lamination 7, enter in the longitudinal drainage pipe 4 from collection hole 5, by transverse drain 6 rainwater is exported then, the other end of transverse drain 6 is connected on the gathering-device (can connect collecting box or collecting pit) of rainwater.So just can obtain the higher road surface rainwater of water quality, improve collection and utilization rate, can fundamentally check spreading of ecological environment crisis rainwater.
