Shipping accident, not only can produce baneful influence, or even entail dangers to population health and life security, cause tremendous economic to water environment
Loss.Prior art mainly takes the mode for arranging pavement runoff collecting pit to mitigate pavement runoff to Highways ' sensitive water body
Affect, again while undertaking the function of leakage liquid collecting in harmful influence leakage accident.Existing highway road surface collecting pit is primarily present
Following deficiency：First, only serving collecting action to Highway Rainfall Runoff, purified treatment is not carried out to which, therefore cannot be carried out
Highway planting etc. is comprehensively utilized；Second, Highway Rainfall Runoff collecting pit majority locates below ground level, constantly there is runoff stream in rainy season
Enter, need artificial extraction to empty, operation inconvenience.
The content of the invention
For solving problem above, this utility model provides a kind of easy to operate, function more full filtering type highway pavement footpath
Stream collection and purification pond.
A kind of filtering type Highway Rainfall Runoff collection and purification pond described in the utility model, the collection and purification pond 6 is successively
Including close to sedimentation tank 7, filtering ponds 8 and storage pool 9；7 both sides of sedimentation tank respectively set one piece of training wall 2；Distinguish at 8 two ends of filtering ponds
It is provided with left cutoff board and right cutoff board；Left cutoff board is provided with multiple sedimentation tank overfalls 3, and right cutoff board is provided with multiple filtrations
Pond outlet 5.
A kind of filtering type Highway Rainfall Runoff collection and purification pond described in the utility model, the height of the training wall 2 with
6 cell body of collection and purification pond is highly identical, and direction is parallel with 6 cell body minor face of collection and purification pond.
A kind of filtering type Highway Rainfall Runoff collection and purification pond described in the utility model, the sedimentation tank overfall 3
The half of height is accumulated for 6 cell body basin's effective volume of collection and purification pond highly.
A kind of filtering type Highway Rainfall Runoff collection and purification pond described in the utility model, arranges two in the filtering ponds 8
Layer filler, respectively gravel upper strata 13 and flyash ceramic infra-granular layer 14, cell body bottom arranges filtering ponds outlet 5.
A kind of filtering type Highway Rainfall Runoff collection and purification pond described in the utility model, the height of 9 bottom of pond of the storage pool
Degree arranges exhaust-valve 10 less than sedimentation tank 7 and filtering ponds 8, bottom.
A kind of filtering type Highway Rainfall Runoff collection and purification pond described in the utility model, 3 He of sedimentation tank overfall
Filtering ponds outlet 5 has three.
Compared with prior art, filtering type Highway Rainfall Runoff collection and purification pond described in the utility model is provided with water conservancy diversion
Wall, extends the time of staying of the pavement runoff in sedimentation tank；It is basin's effective volume height that sedimentation tank overfall arranges overflow height
Half, effectively enhance pavement runoff amount it is larger when by the ability of sedimentation tank；Filtering ponds are provided with two-layer filtrate, and filtrate sets
Height of the height less than sedimentation tank downflow weir is put, filtrate porosity is larger, in the case where contaminant removal efficiency is guaranteed, strengthened
Pavement runoff passes through filtering ponds ability；Storage pool bottom of pond is highly relatively low, can keep in a certain amount of filtration pavement runoff.

Specific embodiment
With reference to specific embodiment filtering type Highway Rainfall Runoff collection and purification pond described in the utility model is made into
One step is illustrated, but protection domain of the present utility model is not limited to this.
Embodiment 1
A kind of filtering type Highway Rainfall Runoff collection and purification pond, it is heavy including what is be connected with pavement runoff chute water inlet 1
7, three, shallow lake pond sedimentation tank overfall 3,8, three filtering ponds outlets 5 of filtering ponds and storage pool 9,9 bottom of pond of storage pool are highly low
In sedimentation tank 7 and filtering ponds 8, in certain water storage height, filtering ponds discharge pavement runoff is not interfered with.
After pavement runoff collects Jing gutter 12, sedimentation tank is entered by chute pathway face diameter stream chute water inlet 1
7.Training wall 2 at two are provided with sedimentation tank 7, impact of the pavement runoff to sedimentation tank 7 can be slowed down, pavement runoff is along training wall 2
The flowing of water conservancy diversion direction, extend the time of staying of the pavement runoff in sedimentation tank 7, strengthen sedimentation effect.Sedimentation tank 7 and filtration
Connected by sedimentation tank overfall 3 between pond 8, sedimentation tank overfall 3 arranges half of the overflow height for basin's effective volume height, effectively
Enhance pavement runoff amount it is larger when by the ability of sedimentation tank.Filtering ponds 8 are provided with two-layer filtrate, respectively on filtering ponds
Layer filler gravel 13 and filtering ponds lower floor filler lytag 14, height of the filtrate rational height less than sedimentation tank downflow weir 3,
Filtrate porosity is larger, in the case where contaminant removal efficiency is guaranteed, strengthens pavement runoff and passes through 8 ability of filtering ponds.Filter
Connected by filtering ponds outlet 5 between pond 8 and storage pool 9, filtering ponds outlet 5 is located at the bottom of filtering ponds 8, therefore, filter
Pond 8 has certain oil removal function, and after filtering ponds outlet 5, pavement runoff flows into storage in storage pool 9, can extract use
In periphery highway planting.9 bottom of pond of storage pool is highly relatively low, can keep in a certain amount of filtration pavement runoff.9 bottom of storage pool is arranged
Exhaust-valve 10, when afforesting using the pavement runoff of storage, opens exhaust-valve 10, when storage pool inner storing water amount is larger, the row of unlatching
Empty valve, excludes stock solution, and the remaining pond of increase holds.
When there is harmful influence shipping accident, harmful influence leakage fluid Jing gutters 12 are collected, and pathway face diameter stream chute enters
The mouth of a river 1 enters pavement runoff and collects processing pond 6, and sedimentation tank 7, filtering ponds 8 can store harmful influence leakage fluid with storage pool 9, after
Phase can be opened exhaust-valve 10 and be will leak out liquid discharge process.After harmful influence leakage fluid is received, in filtering ponds 8, filtering ponds filler 4 is needed
New filtrate is replaced by all.
