To keep the purpose of this utility model, technical solution and advantage clearer, below to the utility model embodiment
It is described in further detail.
Embodiment 1
A kind of buried biological delaying basin based on original greenbelt, i.e., the selected greenbelt for needing to be transformed determine its ruler
Very little and underground buried depth, designs and manufactures a kind of biological delaying basin of vertical current, by the topsoil of original greenbelt and its plant
Migrate to the filler surface layer of biological delaying basin, maintenance, plantation.It is buried to refer to biological delaying basin being arranged in original greenbelt
Place below ground.The utility model embodiment helps to improve the arrangement efficiency of biological delaying basin, improves the rainwater water of collection
Matter keeps original greening state.
The utility model embodiment discloses a kind of buried biological delaying basin based on original greenbelt, referring to Fig. 1, packet
It includes: curb entrance 1, biological delaying basin 2, filtering rainwater-collecting pipeline 3 and overflow pipe 4.
Referring to fig. 2, which includes: coating 2-1, filter layer 2-2, transition zone 2-3, drainage blanket 2-4, row
Water blind pipe 2-5 and plant 2-6.
(1) device working principle
Behind rain drop erosion road surface, entered in biological delaying basin 2 by the curb entrance 1 of road.Rainwater passes through vertical and water
Flat flow direction passes sequentially through coating 2-1, filter layer 2-2, transition zone 2-3, drainage blanket 2-4, passes through draining blind pipe 2-5 stream
Biological delaying basin 2 out, completes the filtering and purification of rainwater.The rainwater for flowing out biological delaying basin 2 enters filtering rainwater-collecting pipeline
3, according to the later period requirement of rainwater, flow ipe, equipment or underground.
Coating 2-1, filter layer 2-2, transition zone 2-3, drainage blanket 2-4 in biological delaying basin 2, draining blind pipe 2-5 and
Plant 2-6 is respectively as follows:
Coating 2-1: effect is 1. to protect filler (including filter layer 2-2, transition zone 2-3, the draining of biological delaying basin 2
Layer 2-4 and draining blind pipe 2-5) and plant 2-6, prevent rain drop erosion from leading to filler deformation and soil erosion；2. guaranteeing soil
There are enough moisture content, plant preferably grows；3. wetland environment can also allow microorganism to be more effectively carried out life
Object chemical reaction, improves purifying water effect.
Filter layer 2-2: being to contain planting soil, microorganism in filtering layer, 1. main function is most important one layer in filler
The filtering of biological delaying basin 2, purification, absorption, degradation function are completed in this layer substantially；2. root system of plant is generally embedded in this layer, because
This filter layer 2-2 provides well suitable growing environment for plant.
Transition zone 2-3: main function is 1. to prevent from the filler in filter layer from entering drainage blanket to cause line clogging and water and soil
It is lost, protects the draining blind pipe 2-5 in drainage blanket 2-4；2. uniformly transferring the pressure transmitted downwards from filter layer；
Drainage blanket 2-4: effect is the rainwater that 1. discharge is filtered by biological delaying basin 2；2. draining blind pipe 2-5 is laid on row
In water layer 2-4, therefore drainage blanket 2-4 also has the function of protection draining blind pipe 2-5, and the pollutant for such as avoiding shape sharp is to row
The cutting of water blind pipe 2-5；
Draining blind pipe 2-5: the water and soil that effect is to maintain in biological delaying basin 2 balances, and extra water in device for transferring makes net
Biological delaying basin 2 can be smoothly discharged in the rainwater of change；
Plant 2-6: being the important component of biological delaying basin 2, and function and feature include: 1. to adsorb, be enriched with pollution
Object；2. being conducive to microbe survival；3. providing oxygen and energy, the ecosystem is kept to stablize；4. accumulating organic matter.
To prevent from flowing into the amount of rainfall of biological delaying basin 2 beyond processing capacity, causes rainwater to overflow, pollute biological delaying basin
Region around 22, installs overflow pipe 4, and the rainwater higher than 4 entrance of overflow pipe can be arranged by the entrance of overflow pipe 4
Out.
(2) arrangement
Range in the determining place measurement greening region for needing to be transformed into biological delaying basin 2, size is biology
The size of delaying basin 2.According to the connection of resulting size and underground piping, by the producer of biological delaying basin 2 to equipment
It is produced and is processed, including curb entrance 1 and outer wall production, filler and the laying for draining blind pipe 2-5 etc..Wherein, filter layer
2-2 is only laid with certain thickness, does not need to be fully filled with；Coating 2-1 is not laid with temporarily.
By the plant planted in original afforested areas together with topsoil, root system together dig remove afforested areas it is spare, to the greatest extent
Amount protection changes its appearance not.
Excavate the remaining soil of original afforested areas, biological delaying basin 2, curb entrance 1 can be placed by making to hollow out area just
Height it is almost the same with road, so that road rain water is smoothly flowed into curb entrance 1.It is carrying out cleaning appropriate and is stablizing to add
Gu after, whole be placed in of the biological delaying basin 2 made is hollowed out into area, by the draining blind pipe 2-5 of biological delaying basin 2, filtering rain
Water collection pipe road 3, underground piping are rationally connected, so that purified rainwater is smoothly discharged, such as lead to water tank, garden fills
Irrigate pipeline, infiltration area etc..Plant 2-6 and the topsoil plantation for digging removal before are covered in packing area surface layer, then
Certain maintenance is carried out, it is appropriate to be laid with coating 2-1, so that from the appearance, plant 2-6 is almost the same before and after excavation.
The utility model embodiment discloses a kind of buried biological delaying basin based on original greenbelt and can filter, only
Change road rain water, improves Rainwater Quality and utilization rate；Meanwhile equipment is provided with overflow pipe, dirt caused by preventing rainwater from overflowing
Dye.
