Description
Invention field
The present invention relates to reservoir drawdown band bank slope protection technology, be related specifically to a kind of reservoir drawdown band bank slope protection deal pile-stone
Raw retaining wall is planted in the combination of cage net.
Background technology
Reservoir drawdown band, also known as eat and flow zone or fluctuation district, refers to that reservoir makes periphery flood soil periodically because of seasonal fluctuation in stage
Ground exposure is in a special region of the water surface.Falling zone formed between reservoir area water body and land bank huge ring storehouse ecological every
From band, it is that a kind of special land and water interlocks wetlands ecosystems.Three Gorges Reservoir takes the operating scheme of " clear row is turbid for poultry ", causes
Upstream occurs that drop reaches the falling zone of 30 meters.Periodically washed away by water body due to bank slope and flood, in region, falling zone originally
Plant gradually dead disappear, cause a large amount of earth exposed, severe water and soil erosion, induce many places collapse on the bank, landslide, threaten water
Normal performance, the life property safety of the people and the sustainable development of ecology in reservoir area system of diuretic electrical engineering function.Falling zone is subject to
Storehouse bank runoff and reservoir water wave impact erosion, be more likely formed soil erosion, bank body avalanche, not only can not play the isolation to water body
Defencive function, can carry more pollutant on the contrary and silt threatens reservoir area water quality and the safety of dam.Meanwhile, former in falling zone
The terrestial enviornment come changes into water winter, land summer alternate environment, has the features such as flooding time length, fluctuation in stage amplitude are big.Typically plant
Thing is difficult in adapt to, and often falls after rise in naked state water level, and arid is thin and weak, is then flooded for a long time after rising of groundwater level.And usual water plant
Not drought resisting, xerophyte is weak to flood, and lean thin domatic environment more limits plant growing, similar " desertification " view of generation
Inharmonious also by the development of restriction Reservoir region tourist industry, administer and there is the biggest difficulty.
At present, reservoir drawdown band bank slope protection technology the most only puts undue emphasis on the functions such as flood control, diversion, water drainage, water-retention, less
Consider the harmony in river and the ecological environment of periphery.Bank is carried out frequently with the rigid protection means such as concrete, cemented rock
Slope is protected, and only payes attention to the flood control function of bank protection structure, have ignored the ecological effect in river, river completely by manual, channelization,
Destroying original ecological balance, and its volume, weight are big, material therefor is many, and operating expenses is high, and artificial trace is serious, does not has
There are ecology and landscape function;After rigid protection builds molding by laying bricks or stones, making water system be separated with soil and biotic environment thereof, many moving is planted
Thing cannot be survived, and breaks the ring biological chain of natural river, and bank slope of reservoir can not filter rainwash and purify water, destroying life
State environment;And traditional stone is gloomy with concrete color, surface is dull, gives stiff, coarse, the vision effect of ash cooling
Really, it is impossible to play the effect beautified the environment, more can not adapt with surrounding enviroment.Obviously, prior art reservoir drawdown band bank slope
Means of defence also exists the ecological environment etc. of functions such as only focusing on flood control, diversion, water drainage, water-retention, less consideration river and periphery
Problem.
Summary of the invention
The functions such as flood control, diversion, water drainage, water-retention are only focused on for what solution prior art reservoir drawdown band bank slope protection method existed,
The problems such as the ecological environment of less consideration river and periphery, the present invention proposes a kind of reservoir drawdown band bank slope protection deal pile-gabion box
Raw retaining wall is planted in combination.Raw retaining wall is planted in reservoir drawdown band bank slope protection deal pile of the present invention-gabion box combination, including, gabion box,
Deal pile, graded broken stone layer, anti-filter geotextiles and GSZ;Gabion box is to use braided steel wire or the rectangle that is welded into netted
Boxes and baskets, are ladder-like arranged from lower to upper along retaining wall longitudinal axis and the two rows fissure of displacement is staggered, and fill inside gabion box
Having can the packeted soil of cultivated plant;Rows of deal pile is set in gabion box inner side and outer side, is positioned at the gabion box two of basic part
The deal pile of side inserts in ground, and the outside deal pile being positioned at upper strata gabion box inserts in lower floor's gabion box, and inner side deal pile inserts
After wall in the soil body, between adjacent deal pile, connect into entirety with the rope made of hemp;It is provided with grating between the soil body after inner side deal pile and wall
Metalling;It is provided with anti-filter geotextiles between the soil body between outside deal pile and gabion box and after graded broken stone layer and wall;In phase
Between adjacent bed gabion box and after adjacent layer wall, between the soil body, GSZ is set;The width of described graded broken stone layer is
20cm~40cm.
Further, reservoir drawdown band bank slope protection deal pile of the present invention-gabion box combination plants raw retaining wall, at bottom gabion box
Inner side is provided with Masson Pine frame, is provided with plant floating bed at Masson Pine arch, and Masson Pine frame is fixed up with plant floating bed rope;Institute
Stating Masson Pine frame is that to form cross sectional shape be trapezoidal casing in Masson Pine colligation, is filled with cobblestone in casing;Plant floating bed for arranging
There is the floating mat of implantation hole, filling soil in implantation hole, and plantation emergent aquactic plant.
Further, raw retaining wall is planted in reservoir drawdown band bank slope protection deal pile of the present invention-gabion box combination, and the steel wire of gabion box is
High-strength corrosion-resistant steel wire or be coated with the high-tensile steel wires of PVC;The height of gabion box is 80cm~120cm, and height and wall
The height of the rear soil body matches.
Further, raw retaining wall is planted in reservoir drawdown band bank slope protection deal pile of the present invention-gabion box combination, and each gabion box is upper and lower
With the high-tensile steel wires being coated with PVC, adjacent gabion box colligation is connected at four angles.
Further, raw retaining wall is planted in reservoir drawdown band bank slope protection deal pile of the present invention-gabion box combination, and deal pile inserts ground
Or the degree of depth in the soil body is not less than 80cm in lower floor's gabion box or after wall.
