Description
Technical field
The present invention relates to a kind of ecological revetment with bank pollution of area source purification function, specific environment protection technique necks
Domain.
Background technique
Revetment is also referred to as slope protection, refers to that below ground along the river is built, protects riverbank from washing away or avalanche is constructed
Object is generally used for gardens or urban landscape river two sides.Traditional river revetment generally uses concreting or stone to grout and refutes
The mode of bank, plant are not easy to grow, and hard revetment lacks aesthetic feeling, reduce perception effect.In addition, hard revetment has blocked river
The lateral ties of the ecosystem, water body and river soil can not carry out mass exchange, reduce river purification ability.Especially
It is municipal rainwater discharge, natural precipitation, the sewage containing substances such as nitrogen, phosphorus and heavy metals is right directly along revetment fair current to river
It causes seriously to pollute in river.City river of today has the function such as flood control and water drain, Landscape Culture, ecological environment and making use of rain and flood
Can, therefore, builds a kind of ecological revetment with bank pollution of area source purification function and be of great significance.
Summary of the invention

Ecological groove (2) is by groove gravel layer (9), groove zeolite layer (10), groove haydite layer (11), groove planting soil layer
(12), water storage tank (13) and emergent aquactic plant (15) are constituted；Ecological groove (2) is equipped with water storage tank (13), the bottom in water storage tank (13)
Layer be groove gravel layer (9), be followed successively by thereon groove zeolite layer (10), groove haydite layer (11), groove planting soil layer (12) and
Emergent aquactic plant (15)；Wherein, the grain size of gravel of groove gravel layer (9) is 0.3-0.6cm, and laying depth is 30 ± 5cm；Groove boiling
Rock layers (10) sized zeolite particles are 0.6-1.0cm, and laying depth is 30 ± 5cm；Groove haydite layer (11) haydite partial size is 1.0-
1.5cm, thickness are set according to revetment actual grade, minimum thickness 20cm；Groove planting soil layer (12) with a thickness of 20 ±
5cm；
Lower end turf growth belt (3) is by lower end turf gravel layer (16), lower end turf zeolite layer (17), lower end turf planting soil layer
(18) it is formed with turf (8)；Lower end turf growth belt (3) lower end turf gravel layer (16) shop fixtures, is successively arranged lower end thereon
Turf zeolite layer (17), lower end turf planting soil layer (18) and turf (8)；Wherein, lower end turf gravel layer (16) grain size of gravel
For 0.3-0.6cm, laying depth 10-15cm；Lower end turf zeolite layer (17) sized zeolite particles are 0.6-1.0cm, laying depth
For 20 ± 5cm；Lower end turf planting soil layer (18) is with a thickness of 20 ± 5cm.
The water storage tank (13) by the way of concreting, by slot bottom (13-1), upper end cell wall (13-2) and under
End slot wall (13-3) is constituted；Slot bottom (13-1) wide 100 ± 20cm, base thickness are 30 ± 5cm；Lower end cell wall (13-3) is highly set as
50 ± 10cm, upper end cell wall (13-2) are highly set according to revetment actual grade, and the wall thickness of upper/lower terminal cell wall is 20 ±

The invention has the benefit that
Relative to traditional revetment, ecological revetment of the present invention sets up upper end turf growth belt (1), ecological groove (2), lower end turf kind
Band (3) and slope foot (4) are planted, single concrete revetment structure is changed, had not only weakened bank pollution of area source, but also improve sight
Sense.
When flowing through upper end turf growth belt (1), rubble layer (6) is uniformly laid with rainwash by flat rubble, rubble and hair
Irregular crack of stone is formed between stone, is formed overflow ducts, is facilitated overflow of the earth's surface percolating water on rubble layer (6) to ecology
Groove.The surface water of infiltration flows into ecological groove (2), soil particle and solid through stainless steel protection net (14) under the effect of gravity
Impurity is blocked due to geotextiles (14-2's), will not be by water flow erosion.In addition, stainless steel protection net uses SS304 stainless steel
(14-1), anti-shock loading with higher, fixed upper end turf growth belt (1) prevent upper end turf growth belt (1) from gliding.
Ecology retention, the purification of upper end turf growth belt (1), reduce the solid impurity and pollutant in rainwash.
The groove zeolite layer (10) of ecological groove (2) has adsorptivity, ion exchangeable, can deep purifying and absorption upper end
The rainwash of turf growth belt (1) overflow.Groove haydite layer (11) has many advantages, such as impervious excellent, large specific surface area, energy
Water conservation is needed for plant growth.Groove gravel layer (9), groove zeolite layer (10), groove haydite layer (11) can be used as micro-
Bio-carrier forms biomembrane, plays the role of chitosan fluid dressing, heavy metal pollution and organic contamination in purification and elimination water.
In addition, planting emergent aquactic plant, root system membrane, biodegradable water pollutant in groove planting soil layer (12).In mixed filler layer
Under the double action of root system of plant, pollutant concentration is greatly lowered.Meanwhile water storage tank (13) retains surface water, meets
The growth of emergent aquactic plant needs, and realizes the effect of ecologic planting.
Finally under the effect of the deep purifying of the turf of lower section turf growth belt (3) and packing layer, rainwash is through slope foot
(4) overflow to river, pollutant is basically eliminated, and alleviates pollution of the rainwash to river, realize the function of revetment with
Landscape is unified.
