Specific embodiment
It elaborates with reference to the accompanying drawing to embodiment.
Embodiment: as shown in Figures 1 to 6, a kind of ecological bank protection structure efficiently using river bottom mud is mainly kept off by shore protection
Cob wall 3 is planted layer 1 and is covered and plants the composition of layer 2, covers plant layer 2 and is covered on above-mentioned plantation layer 1, shore protection retaining wall 3 and above-mentioned plantation layer
The 1 angled geotechnical grid with geotechnological checkerwork cell 61 for being arranged and being fixed on river side, plant that laying on layer 1 is in streamline grid type
6, bed mud also sprays bottom into geotechnical grid 6 in above-mentioned geotechnical grid 6, while by injection apparatus from injection after river extraction
The substances such as mud modifying agent, curing agent and fibre plant, fibre plant are stringy solids, and ingredient is shredded coconut meat or stalk, and raw material is easily received
Collection.Use cost is low, and the addition of curing agent and fibre plant keeps bed mud easily blocking, bed mud is prevented to be lost, while can strengthen bed mud
Structure, 6 upper layer of geotechnical grid are to cover to plant layer 2, plant enriching plant, aperture is densely distributed, so that the enriching plant root system of every room
It mutually grows, staggeredly, so that bank protection structure is stronger, avoids the adverse effects such as landslide.
It covers and plants layer 2 on plantation layer 1, every lattice geotechnical grid 6 uniformly sprays vegetable seeds, is changed according to river water level, is covered
It plants, 2 points are humidogene area and bank slope area, and Plants selection super enriching plant can effectively adsorb heavy metal and nitrogen phosphorus etc. in bed mud and seek
Substance is supported, can be after planting plants after bed mud solidification, sample detection bed mud content of material ingredient determines the kind covered and plant layer plant according to this
Class.
Shore protection retaining wall 3 includes shore protection barricade outer layer 34 and shore protection barricade internal layer, and above-mentioned shore protection barricade internal layer includes barricade
Layer 33, barricade middle layer 32 and barricade fixing layer 31 are planted, above-mentioned barricade fixing layer 31 is concrete layer, by concrete material
Piling is made, and above-mentioned barricade fixing layer 31, barricade middle layer and barricade plantation layer 33 are set gradually from bottom to top, above-mentioned shore protection gear
The U-shaped structure of wall outer layer 34, is stacked by porous brick, is connected between 3 surface layer of shore protection retaining wall and plantation layer 1, can be in time
The moisture flowed down from plantation layer 1 toward river direction is leaked, moisture includes moisture, rainwater and rainwash contained by sprinkling bed mud
Deng other moisture, above-mentioned barricade middle layer is upper layer 321 and barricade immediate underlying layer 322 among modified zeolite layer, including barricade, on
State the FeZn-LDHs modified zeolite for being 5~10mm filled with partial size in upper layer 321 among barricade, above-mentioned barricade immediate underlying layer 322
The FeZn-LDHs modified zeolite for being 10~20mm filled with partial size, FeZn-LDHs modified zeolite divide different-grain diameter to fill full barricade
Intermediate upper layer 321 and barricade immediate underlying layer 322 can be filtered the moisture that plantation layer 1 leaks, nitrogen, phosphorus etc. in adsorption moisture
Nutriment, purification flow into the water quality in river.
3 top of shore protection retaining wall is slightly above 4 ordinary water level of river water face, avoids water flow directly washing away to plantation layer 1, influences to plant
The quality of layer 1 is planted, and shore protection retaining wall 3 stops plantation layer 1 for bearing the lateral stress of plantation layer 1 perpendicular to river water face 4
It glides.
Plantation layer 1 is covered by the geotechnical grid 6 with geotechnological checkerwork cell 61, and 6 ingredient of geotechnical grid is high density polyethylene (HDPE)
(HDPE), chemical property stabilization, resistance to oxidation, acid and alkali-resistance, will not pollute, Tu Gongge, and 6 are arranged in streamline grid-shaped, have
There is the geotechnological checkerwork cell 61 of 4 pieces of dense distributions at certain retractility, four sides, are in " matrix pattern ", and geotechnological checkerwork cell 61 divides 3 layers, every layer
Distribution 6, the block of " matrix pattern " enable the root system for covering the plant on plant layer 2 to grow by geotechnological checkerwork cell 61, staggeredly, increase
The strong fixed function of root system, reduces a possibility that bed mud flows back through water, reduces river secondary pollution to a certain extent,
The non-porous sections of the block of " matrix pattern " have obstructed the reflux of plantation layer contained humidity from upper, middle and lower-ranking, extend and cover plant layer
On 2 plant to organic pollutant, heavy metal, nutriment adsorption time, strengthen cover plant 2 plant of layer suction-operated, prolong
The radial pressure of shore protection retaining wall 3 is delayed.
The floristics for planting layer 2 is covered according to the selection of the heterogeneity of bed mud, and the higher bed mud of Ni metal content covers plant, and 2 is wet
Dayflower is planted at raw area's plantation cyperus alternifolius, bank slope；The higher bed mud of metal Pb content covers and plants 2 humidogene area of floor plantation east perfume
Vetiver is planted at Pu, bank slope；The higher bed mud of nutriment phosphorus content covers and plants 2 humidogene area of floor plantation cattail, plants at bank slope
Rye grass, river bottom mud, adhesion agent and the fibre plant of the sprinkling of bed mud injection apparatus are planted covering, 2 surfaces mixing, after moisture runoff
Clod is formed, plant growth is easy to, the plant for covering plant layer 2 plays the role of three, first is that root system can preferably absorb in bed mud
Various pollutants matter plays the role of processing and recycles bed mud；Second is that root system is fixed on plantation layer, the water of plantation layer is alleviated
Soil flow is lost, and the service life of ecological revetment is enhanced；Third is that improving greening and the landscape utility of entire ecological revetment.
Angle between shore protection retaining wall 3 and above-mentioned plantation layer 1 is set as 30 °~90 °, alleviates shore protection retaining wall 3
Radial pressure ensure that the service life of shore protection retaining wall 3, reduce construction cost.
Continuous three layers of design in ecological revetment, so that the utilization rate of river bottom mud is promoted, shore protection repair is strong, avoids
Sediment improper bring secondary pollution, the treatment in situ of bed mud, labour cost is low, and engineering construction is easy, ecological benefits
It is high.
Whole ecological bank protection structure design is reasonable, novel, has the advantage that
One, shore protection retaining wall 3 filtering and suction-operated it is obvious, structure design so that filler be conducive to replacement, it is high-efficient；
Two, the design planted layer 1 and cover plant layer 2 strengthens adsorption effect, has done specific aim processing to soil erosion, greatly
Ground improves the utilization rate of bed mud, reduces pollution, has given full play to the ecological benefits of bank protection structure, can effectively handle bottom
Mud；
Three, the floristics for planting layer 2 is covered by classifying and selecting after Soil K+adsorption, and specific aim is had more to the absorption of polluter.
