Abstract

The invention relates to a method for forming an ecological embankment of vertical revetment live branch bundles. The method is characterized in that a row of wood piles or concrete imitative wood piles is driven along the bankside toe line of a riverway, twigs of willows, alders or black poplars are bunched into live branch bundles, gravels, pebbles, haydites and zeolites are filled in the live branch bundles, and the live branch bundles are arranged between the wood piles or the concrete imitative wood piles and the bankside of the riverway parallel to the riverbank. Therefore, the problems of renovating vertical revetment waterfront plants along the riverway and constructing an ecological embankment are solved. The live branches used by the embankment have good tolerance to water logging, thereby quickly budding and forming a vegetation system, creating good living environment for riverbank living things, and beautifying riverbank landscape, and on the other side, plants, purifying filter materials and surface-attached microorganisms have better purifying effects on pollutant and improve the water quality of the riverway. The embankment is very convenient to construct, maintain and manage, and has better transformation and application prospects of the ecological renovation of the vertical revetment.

Description

The forming ecological embankment of vertical revetment live branch bundles method
Technical field
The present invention relates to a kind of ecological river shore protection constructing technology, particularly a kind of forming ecological embankment of vertical revetment live branch bundles method.
Background technology
Embankment of vertical is common river course bank slope form, especially uses very general in city river.Before the present invention, the shore protection technology of existing river course embankment of vertical is mainly hard type shore protection technology.
Hard type shore protection mainly adopts and grouts or placed rockfill, cast-in-situ concrete, precast concrete block etc. protect the river course bank slope.These structures are for keeping bank stability, prevent erosion and ensure that flood control safety has preferable effect, but also in varying degrees to the ecology of bank slope, environment and view have produced harmful effect: its hard material and enclosed construction have destroyed the staggered band in land and water, river course, make bank biological habitat in shore lose, animals and plants are difficult in this existence procreation, heavy damage bio-diversity, cause the self-purification capacity of river water body obviously to descend, the pollutant that enters the river course with face source form is difficult to remove, and its smooth and dull apparent landscape effect that has a strong impact on the river course.
For overcoming the defective of hard type shore protection, repair shore, river course bank band ecological environment, people bring into use the ecology typed bank revetment technology, as Impurifying source ecological bank-protection combined system (CN200610096765.5), landscape type multi-stage stepwise artificial wetland protection slope forming method (CN200410065916.1), the slope type ecological revetment (CN200710036262.3) of band barricade, irrigation canals and ditches river sloping bank constitution wetland effluent sewage processing method (CN200310106558.X), floating ecological bank protecting method and medium carrier (CN200610038576.2), the construction method of framed structure ecological riverway embankment (CN200810238006.7), environmental polygon concrete revetment plate with holes and the application process in shore protection (CN200610148054.8) thereof, environmental concrete revetment cylindrical shell and the application process in shore protection (CN200610148053.3) thereof, the engineering method (CN200410010692.4) etc. that recovers the degeneration riverbank with reed protects the river course bank slope, these technology have better effects and make the bank slope view obtain certain improvement stablizing the bank slope structure, and have certain ecology and clean dirty function, but these technology are mainly used in ramp type or the compound bank slope.At present, the shore water phytoremediation of embankment of vertical and ecological revetment make up and are still a technical barrier.
Summary of the invention
Purpose of the present invention just is to overcome the defective of above-mentioned embankment of vertical slope protecting technique, develops the ecological revetment technology of the good river course embankment of vertical of a kind of comprehensive effect.
Technical scheme of the present invention is: a campshed body is made a call in road bank slope payment to a porter along the river, lay geotextiles in pile body backwater one side, lay piece stone at pile body towards the angle in water one side and riverbed, the spray of willow, alder tree or black poplar tree is bundled into live branch bundles, in live branch bundles, fill and purify filtrate, live branch bundles is put between pile body and the river course bank slope by the mode parallel with the riverbank, live branch bundles is all covered with soil; When described river course bank slope is soil property river course bank slope, excavate former river course bank slope, newly excavate riverside slope identity distance pile body 1~2m, and in the domatic laying geotextiles in new excavation riverbank; When described river course bank slope was hard river course bank slope, pile body was apart from embankment of vertical 0.5~1.0m; Described pile body is the imitative timber of timber or concrete; Described purification filtrate is gravel, cobble, haydite and zeolite.
Advantage of the present invention and effect are: the branch of living that this shore protection adopts has the well anti-performance of flooding, can sprout rapidly and form vegetation system, built the biological habitat in good riverbank, before embankment of vertical, formed green screen one, the visual effect of the embankment of vertical dullness that weakened on the one hand, beautified the riverbank view, plant, the microorganism that purifies filtrate and surface attachment thereof have preferably clean-up effect, have improved river water quality pollutant on the other hand.Construction of this shore protection and maintenance management are all very convenient, are very suitable for the restoration of the ecosystem of embankment of vertical.
The present invention implements and has obtained effect preferably in the test of test place, on-the-spot contrast test by the present invention and hard embankment of vertical implementation result, find that the present invention has the more significant clean-up effect of holding back than hard embankment of vertical to pollution of area source, as shown in table 1.
The on-the-spot comparative test result of table 1
