Fig. 2 is anti-blocking permeable pavement structure schematic diagram.
Anti-blocking permeable pavement structure 1, anti-blocking porous pavement layer 11, open gradation bed course 12, open Level mixes basic unit 13, and open gradation goes to a grassroots level 14, non-compacted foundation soil 15, drain pipe 2, Geotextile layer 3, perforated pipe 4, sand setting distribution pond 5, purify storage pond 6, the first bright well 61, the second bright well 62, the first stealthy well 63, the second stealthy well 64, the second stealthy well 65, Infiltration well 7, greenbelt tank 8.
Detailed description of the invention:
Embodiment 1: for the rainwater-collecting cleaning system of urban afforestation, it includes anti-blocking permeable Pavement structure 1, for distribute rainwater sand setting distribution pond 5, for filtering rain water purification Storage pond 6 and for permeating the infiltration well 7 of rainwater;Anti-blocking permeable pavement structure 1, sand setting divide Distribution reservoir 5, purification storage pond 6 and infiltration well 7 are sequentially communicated by pipeline, and infiltration well 7 leads to Cross pipeline connection to greenbelt tank 8.
Anti-blocking permeable pavement structure 1 includes: anti-blocking porous pavement layer 11, anti-blocking porous pavement It is sequentially provided with basic unit 13, open gradation on open gradation bed course 12, open gradation below layer 11 to go to a grassroots level 14 and non-compacted foundation soil 15;Open gradation is gone to a grassroots level the 14 internal drain pipies being provided with band perforate 2, the outlet of drain pipe 2 connects with sand setting distribution pond 5;Open gradation goes to a grassroots level 14 and non- Be provided with between rammed subgrade soil layer 15 prevent soil particle blocking open gradation go to a grassroots level 14 geotechnique Tissue layer 3.Anti-blocking porous pavement layer 11 is paved for anti-blocking water-permeable brick and is formed.Normal precipitation feelings Under condition, rainwater first passes around anti-blocking porous pavement layer 11 and filters, and bulky grain is trapped, and makes phase To clean rainwater infiltration.Rainwater basic unit 13 and on open gradation bed course 12, open gradation again Open gradation is gone to a grassroots level and is entered drain pipe 2 after 14, carries to follow-up system from drain pipe 2.Root According to different needs, anti-blocking porous pavement layer 11 for anti-blocking water-permeable brick or other there is water penetration Carrier pave and form.Under big rainfall precipitation event, it is possible to cause drain pipe 2 to be in full Load state, then the rainwater being introduced into drain pipe 2 will be by action of gravity, through geotextile layer 3 Ooze under after non-compacted foundation soil 15, supplement urban groundwater.Non-compacted foundation soil 15 Substantially soil particle, after water penetrates into there is the possibility upwards adsorbed in soil particle.But it is because The existence of geotextile layer 3, make open gradation go to a grassroots level 14 and non-compacted foundation soil 45 realize It is relatively isolated, prevents soil particle blocking open gradation from going to a grassroots level 14, it is ensured that land drainage Smooth and easy.
The pool wall in sand setting distribution pond 5 uses silica sand drainage building block to make, and uses waterproof at the bottom of pond Material is made;Being provided with sand setting distribution pond baffle plate in sand setting distribution pond 5, sand setting distributes Pond baffle plate is arranged along the axis in sand setting distribution pond 5, and distributes pond 5 with entering sand setting Water inlet pipe is correspondingly arranged.
Purify the first bright well 61, stealthy well and the second bright well that storage pond 6 includes being sequentially communicated 62;First bright well 61 connects with sand setting distribution pond 5, and the second bright well 62 is with infiltration well 7 even Logical, stealthy well includes the first stealthy stealthy well 64 of well 63, second and several the 3rd stealthy wells 65, the first stealthy well 63 communicates in bottom with the first bright well 61, the second stealth well 64 and the One stealthy well 63 communicates at middle part, between each the 3rd stealthy well 65 and one of them is hidden All communicate in bottom between shape well and the second stealthy well 65.When rainwater is less, rainwater only needs Enter in the first bright stealthy well 63 of well 61, first and carry out filtration, purification, finally penetrate into ground Under, recharge of groundwater.When rainwater is more, the rainwater entering the first stealthy well 63 can be therefrom Portion enters and carries out in the second stealthy well 64 and the 3rd stealthy well 65 storing, filters, purifies, so Laggard entering to permeate in well 7, then carry out filtering, purifying, unnecessary rainwater enters greenbelt water storage In pond 8.
The borehole wall and the shaft bottom of infiltration well 7 are permeable structure, in all sides and the bottom of infiltration well 7 All it is sequentially provided with metalling and permeable geotextiles;Second bright well 62 and infiltration well 7 are by perforation Pipe 4 connects;Perforated pipe 4 is connected to the second bright well 62 and the top of infiltration well 7, and tilts It is arranged in metalling;Perforated pipe 4 connects the height of second bright well 62 one end and oozes higher than connection The height of well 7 one end thoroughly.Common, perforated pipe 4 is connected to the second bright well 62 and infiltration well The top of 7, and be obliquely installed in metalling.Why it is arranged at the second bright well 62 and infiltration The top of well 7, is in order to rainwater can be made to smoothly enter the second bright well 62 and infiltration well In 7, when rainwater is few, in the second bright well 62, only just can play the work of filtration, purification With, when rainwater is more, can be entered in infiltration well 7 by perforated pipe 4 and filter, Finally by entering greenbelt tank 8.
