Abstract
There is the plant shallowly careless ditch, including original state soil layer, the second sandy gravel stratum and the second geotextiles filter layer for cutting dirty purification function the present invention is provided to sponge city;Symmetrical shape is respectively arranged with one piece of edge skewback in original state soil layer top side soil between two pieces of sides draining curbs, and side draining curb adjacent thereto fits two pieces of edge skewbacks respectively.Because the first geotextiles filter layer is contacted with rain penetration auxiliary device, pass through the characteristic of sponge material in rain penetration auxiliary device, rainwater can be along the quick seepage flow of rain penetration auxiliary device, because the sponge layered structure overall structure in rain penetration auxiliary device is similar to root system of plant structure, and it is distributed in inside undisturbed soil aquifer in diffusion type, therefore rainwater can rapidly scattering and permeating in undisturbed soil aquifer, accelerate the infiltration coefficient to undisturbed soil soil aquifer, convenient for the quick infiltration of rainwater, reinforce planting shallow careless ditch to the flood storage regulating power of rainwater.
Description
Technical field
The invention belongs to rainwater treatment technical fields, more specifically, in particular to cut dirt for having for sponge city
The plant of purification function shallowly careless ditch.
Background technique
Shallow grass ditch is the key facility of road rain water diafiltration, and shallow grass ditch is that one kind realizes rainwater treatment and resource utilization
Device, it is a kind of engineering that kind has vegetation in earth's surface irrigation canals and ditches that shallow grass ditch, which is also known as Glassed swale, grass planting shallow ridges, grass planting ditch,
Property measure, generally by gravity stream collect handle runoff rainwater.When rainwater flows through shallow careless ditch, in precipitating, filtering, infiltration, suction
Receive and the collective effects such as biodegrade under, most of pollutant in runoff is removed, reach rainfall runoff Collection utilization and
The purpose of runoff pollution control.Since its structure is simple, investment is small, construction is fast, easy to maintain, have very well to small intensity rainfall runoff
Purified treatment effect, while can effectively cut down runoff peak value, moreover it is possible to build good landscape effect, be a kind of promising rain
Water process with utilize facility.
Based on above-mentioned, the inventors discovered that, when amount of rainfall is larger, a large amount of rainwater is difficult quickly to penetrate into soil infiltration
In the saturating lower undisturbed soil aquifer of coefficient, cause a large amount of rainwater can only be discharged by overflow mechanism municipal Storm Sewer Network or its
It is lower to the flood storage regulating power of rainwater to lead to plant shallowly careless ditch for its water body.
Such as application number:The invention discloses a kind of shallow careless ditches, including overflow mechanism, geotextiles by CN201310740304.7
Layer, vegetable layer and planting soil layer, vegetable layer are located above planting soil layer, further include filter layer and aquifer, and filter layer is located at kind
It plants below soil layer and is located above geotextile layer, aquifer is located at below geotextile layer.When rainwater is flowed into shallow careless ditch by road surface
When, rainwater passes sequentially through planting soil layer, filter layer, geotextile layer and aquifer, finally flows into original state soil layer.Due under filter layer
Face is disposed with aquifer, and aquifer can quickly accommodate more rainwater, and original state soil layer lower for soil permeability coefficient stores
Water layer can accommodate rainwater in time, penetrate into original state soil layer again positioned at the rainwater of aquifer, aquifer can quick water storage, pass through peace
Dress filter layer efficiently avoids the case where soil property blocking geotextile layer of planting soil layer, quickly penetrates into aquifer convenient for rainwater,
Effectively improve the flood storage regulating power of shallow careless ditch regional rainwater lower to soil permeability coefficient.
Based on above-mentioned patent, although storing inventors have found that above-mentioned patent temporarily stores rainwater by increased aquifer
The rainwater capacity that water layer itself may store is less, and the flood storage regulating power that can be played is weaker, solution that still can not be basic
The lower problem of original state soil layer rain penetration coefficient.
Then, in view of this, being studied improvement for existing structure and missing, having for sponge city is provided
The plant of dirty purification function shallowly careless ditch is cut, to achieve the purpose that with more more practical value.
Summary of the invention
In order to solve the above technical problem, the present invention provides have the plant for cutting dirty purification function shallowly careless for sponge city
Ditch, to solve when amount of rainfall is larger, a large amount of rainwater is difficult quickly to penetrate into the lower undisturbed soil storage of soil permeability coefficient
Problem in water layer.
The present invention for the shallow grass ditch of plant cut with dirty purification function in sponge city purpose and, by detail below
Technological means is reached:
There is the plant shallowly careless ditch, including original state soil layer, side draining curb, side for cutting dirty purification function for sponge city
It is seeped along skewback, concrete water-storage tank main body, reservoir, overflow well, connecting pipe, subsoil drain, undisturbed soil aquifer, rainwater
Saturating auxiliary device, sponge layered structure, cuts dirty purifying layer, vegetable layer, vegetation plantation layer, the first sandy gravel stratum, the first soil at spongy layer
Work cloth filter layer, intercept layer, the second sandy gravel stratum and the second geotextiles filter layer;Original state between two pieces of side draining curbs
Symmetrical shape is respectively arranged with one piece of edge skewback in the soil of soil layer top side, and two pieces of edge skewbacks respectively with

Column-shaped is connected with the overflow unit that several groups are connected with the reservoir altogether, and every group of overflow unit is in left and right pair by two
The overflow well claimed is formed;Pass through a connecting pipe between two overflow wells in every group of overflow unit
Be connected, and two overflow wells in every group of overflow unit distinguish between the subsoil drain adjacent thereto also by
A piece connecting pipe is connected;Reservoir inner wall bottom end is provided with by second sandy gravel stratum and the second geotextiles mistake
The intercept layer that filtering layer collectively constitutes;The second geotextiles filter layer is located below to connect with reservoir inner wall bottom end
Touching, and the second geotextiles filter layer size is consistent with reservoir inner wall bottom end;The second sandy gravel stratum place mat is in described
The top of second geotextiles filter layer;The reservoir inner wall is from the intercept layer up up to the full original state is filled in open end
Native aquifer;Undisturbed soil aquifer top side is provided with the rain penetration auxiliary device.
Further, the rain penetration auxiliary device is collectively constituted by the spongy layer and the sponge layered structure;
The spongy layer place mat is in the top of the undisturbed soil aquifer.
Further, the spongy layer bottom face is fixedly connected with several groups in time interval arrangement shape and is integrated with formula
The sponge layered structure of structure, and be not in contact with each other between sponge layered structure described in every group.
Further, sponge layered structure described in the several groups that the spongy layer bottom face is fixedly connected is buried in institute
It states inside undisturbed soil aquifer.
Further, the sponge layered structure overall structure in the rain penetration auxiliary device and plant roots tying
Structure is similar, and is distributed in inside the undisturbed soil aquifer in diffusion type.
Further, it is provided with above the rain penetration auxiliary device by the vegetable layer, vegetation plantation layer, the first sand
