Specific implementation mode
The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model
Define.
Refering to attached drawing, a kind of river artificial ecologic island, main body includes two parts：Matrix functional areas and ecological revetment area.It is raw
State bank protection area is arranged outside matrix functional areas, and Eco-Island body height is less than 5~10cm of water body ordinary water level.
Matrix functional areas include river sand layer 11, the first gravel layer 12, the second gravel layer 13,14 and of volcano rock stratum from bottom to top
Dirt bed 15.The gradient of matrix functional areas upstream face is 1:2~1:3, the gradient of matrix functional areas back side is 1:3~1:5.Base
Matter functional areas are mainly by the absorption of filler matrix, filtering, microorganism removal effect and other physics chemical actions come purified water
Matter.
River sand layer 11 is made of the river river sand of 5~8mm, and river sand particle is round and smooth, clean.The optional present situation of 11 river sand of river sand layer
River sand, the medium as mass exchange between island body and bed mud.11 thickness of river sand layer is the 20%~30% of Eco-Island total height.River
Bed course of the sand bed 11 as island body, plays a protective role.
The thickness of the thickness of first gravel layer 12 and the second gravel layer 13 is identical, and thickness is that river artificial ecologic island is total
The 10%~20% of height.The grain size of first gravel layer 12 is more than the grain size of the second gravel layer 13, and the utility model is preferred, the
The grain size of one gravel layer, 12 cobble-stone is 30~50mm, and the grain size of 13 cobble-stone of the second gravel layer is 5~25mm.Gravel has object
Suction-operated is managed, water body purification is haved the function that by the physical absorption of gravel：The absorption of gravel layer surface physics is a part of organic
Object, while the organic matter adhered to can become the important source of nutrition of microorganism, microorganism gradually grows shape in gravel surface aggregation
At biomembrane, purified water by the physiological action of microorganism.Moreover, the porosity of gravel layer is larger, water body stream can be reinforced
It is logical, promote the exchange of water body outside water body and island in island.
The thickness of volcano rock stratum 14 is the 10%~30% of river artificial ecologic island total height, volcanic rock in volcano rock stratum 14
The grain size of filtrate is 5~10mm.The more micropores of volcanic rock rough surface, large specific surface area, be suitble to microorganism its surface growth, it is numerous
It grows, forms biomembrane.Meanwhile volcanic rock filtrate is without sharp particle, aperture is big, small to the resistance of flow, can reduce Eco-Island
To the resistance of flow.
Eco-Island surface layer is dirt bed 15, the thickness of dirt bed 15 be river artificial ecologic island total height 20%~
30%.15 kinds of dirt bed is implanted with water plant.At the top of Eco-Island and the island body peripheral regions of 40cm or more plant emergent aquactic plant

Husky and river silt.The gradient in ecological revetment area is 1:3.3~1:5.
In matrix functional areas, surrounding is laid with one layer of geotextiles 21, and geotextiles 21 have good permeability performance, in dry and wet state
Under can keep adequately strength and elongation, hypothallus filler can be prevented to be lost in, in turn ensure water body inside island and external
It exchanges.
To prevent hypothallus filler to be lost in, while fixed Eco-Island form, when preventing island body by flow big ups and downs
It influences, in 21 outer layer containment mesh fence 22 of geotextiles, grid fence 22 can be wire netting or vegetable fiber blanket.
Surrounding landfill river sand and river silt in matrix functional areas form silt layer 23, and on the one hand fixed Eco-Island form, another
Aspect can be used as the matrix of aquatic plants growth on the body surrounding side wall of island.Island body peripheral regions plantation more than Eco-Island 40cm
Emergent aquactic plant 4, in Eco-Island 40cm island body peripheral regions kind planting submerged plants 5 below.Pass through the purification of kind of planting submerged plant 5
Effect promotes water quality；Water plant root system can fix soil simultaneously, reduce flow and washed away to river silt, and then to Eco-Island
Slope surface plays protective action.The slope control of river silt river sand landfill is 0.2:1~0.3:1, to control the slope in ecological revetment area
Degree.
It is provided with water service pipe 3 in first gravel layer 12, is horizontally arranged, passes through ecological revetment area to be connected to extraneous water body, leads to
It crosses water service pipe 3 and is connected to Eco-Island inside and outside water body, water body is promoted to exchange；Reduce impact of the water body to Eco-Island body.Water service pipe 3 is stretched
Plastic silk screen 31 is tied up to one end system of water body, 31 material of plastic silk screen is polyethylene, and aperture is 3~5mm, and main function is barrier
Big grain size, large volume impurity enter water service pipe 3 to cause water service pipe 3 to block in water body.
It these are only the embodiments of the present invention, it does not limit the scope of the patent of the present invention, every utilization
