Abstract
The invention discloses the domatic silt soil of one kind softening and flinty slope remodeling method, belong to solid wastes recycling and utilize and slope protection works field.Method includes the domatic silt soil of injection softening, soil mud and modified mud and plants raw base material.First to domatic setting anchor pole, carry out reinforcement protection domatic to hard, then carry out linked network construction.After being mixed thoroughly to mud added material, the domatic silt soil of softening is prepared in situ, it prepares main by weight ratio for 5 ~ 10 parts of mud, 1 ~ 4 part of organic acid, 0.5 ~ 1 part of oxidant；Raw base material is planted by spraying soil mud and modified mud again, bank protection is formed.The present invention not only overcomes the problem of ecological poor, hardly possible of flinty slope is afforested, and while base material plant growth formation landscape, soften domatic silt soil can accomplish gradually to soften hard it is domatic, after after certain time, replace original hard domatic, form integration ecological bank protection.Reuse of dredging utilization is carried out, ecological revetment is built, belongs to environment-friendly engineering.
Description
Technical field
The present invention relates to a kind of ecological revetment technique, and in particular to a kind of ecological revetment skill for the domatic transformation of hard
Art, belongs to Geotechnical Engineering field.
Background technology
In urbanization process, because city development intensity is too fast, substantial amounts of flinty slope is paved on river course two sides, changes
Original river channel natural ecology background and hydrological characteristics, destroy natural river course cavernous body, have impact on original water in river course
Native retention property and restoring ecological environment.China is in the starting stage on the research of slope vegetation restoration.Basic research and skill
Art research not comprehensively, imperfection, belong to the desk study stage more.Most of research is only limitted to qualitatively describe root system of plant
Gu Po is acted on and specific construction method.For existing hard handplay renovation technique, mainly there are alien earth sparging, linked network or geotechnique
Grid, sash vegetative protection, thick layer base material spraying technology, plant biological bag greening technique etc..But because the raw techniques intensity of these plants compares
It is low, and there is the adaptability problem with side slope.
The recycling of mud is solid primarily directed to the hot issue that mud yield is big difficult and produces, including mud
The harmless treatments such as change, compost.And for the in-situ treatment of mud, take into account the transformation domatic to hard, seldom refer to, with very
Big research background.
The content of the invention
It is an object of the invention to meet the domatic transformation of hard, restoration of the ecosystem, and meet ecological revetment antiscour, intensity
The particular/special requirement of aspect is applied to the bank protection technique that flinty slope transforms greening there is provided a kind of reuse of dredging, applied to ground
Engineering.
Therefore, provide a kind of domatic silt soil of softening, in terms of parts by weight, including 5 ~ 10 parts of mud, 1 ~ 4 part of organic acid,
0.5 ~ 1 part of oxidant.
The organic acid mainly reaches the domatic effect of softening hard, reaches that making up the domatic isolation of hard plants raw effect；
The oxidant primarily serves the effect of purification mud, can reach slight deodorization, kill the effect of pathogenic microorganism.
According to an aspect of the present invention, the organic acid is organic acid soln, and organic acid and water ratio are 1：（2~5）.
The organic acid is oxalic acid, malic acid, the one or more of citric acid.The oxidant be KMnO4, H2O2 and
K2S2O8 one or more.The jet thickness of the domatic silt soil of softening is 3 ~ 5cm.
The present invention also provides a kind of flinty slope remodeling method, comprises the following steps：
Step 1, remove domatic float stone, it is as smooth domatic as possible；Anchor pole hole position is made with air drill, anchor pole is installed, fixation is domatic；By applying
Work safety standard, order laying galvanized wire mesh simultaneously tighten by tensioning from top to bottom, carries out linked network；
Step 2, linked network carry out the domatic silt soil spraying operation of softening after terminating, in parts by weight, described including following component：Become silted up
6-8 parts of mud, 1-2 parts of organic acid, 0.5-1 parts of oxidant；Injection is sprayed from left to right, from top to bottom when softening domatic silt soil,
Avoid facing upward spray, jet thickness is 3-5cm；
Step 3, fill-before-fire soil mud and modified mud plant raw base material, and thickness is respectively 1-3cm and 8-12cm.
According to an aspect of the present invention, described soil mud is to meet afforestation standard by material process
Silt soil.The modified mud is planted raw base material and is prepared from by mud, soil, adhesive, water-loss reducer, fertilizer and grass seeds.
In a preferred embodiment, in addition to step 4, bedding non-woven fabrics soil moisture conservation.
According to an aspect of the present invention, the modified mud plants mud, 15-25 weight of the raw base material by 30-50 parts by weight
Measure the soil, the adhesive of 5-10 parts by weight, the water-loss reducer of 3-5 parts by weight, 2-6 parts by weight fertilizer and 0.5-1.5 parts by weight of part
Grass seeds be made.
The mud is riverway sludge, because its moisture content is too high, after dewater treatment, and the original of material is used as after paving solarization
Material.
The soil afforests natural soil for the local plantation that is used for asked for, and moisture content is relatively low.
Described adhesive is super absorbent resin, the one or more of poly- polyvinyl acetate emulsion class.
The water-loss reducer is bentonite, the one or more of polyacrylamide.
The fertilizer is organic fertilizer material.
The grass seeds is mainly Festuca Arundinacea, Bermuda grass, Trifolium repense, the one or more of Korea lawn grass.
As it is another preferably, during the injection, concrete sprayer or pump of sowing grass seeds by duster spray from left to right, from top to bottom,
Avoid facing upward spray, angle as far as possible with it is domatic vertical, do not stay dead angle.The domatic silt soil of first spray softening, fill-before-fire soil mud.Finally
The modified mud of injection plants raw base material, the soil moisture conservation of bedding non-woven fabrics.
Take oxalic acid to be modified mud, while raw base material plant germination and growth formation green landscape is planted on upper strata, utilize grass
Aching and limpization hard is domatic, reaches and overcomes the domatic shortcoming for stopping plant growth of hard；Middle level injection soil mud is to hinder
Keep off the mud base material that oxalic acid destroys upper strata；When oxalic acid reaction is most again, upper strata base material root system passes through following silt soil, until taking root
Domatic following in hard, replacement hard completely is domatic, forms ecological revetment.
Compared with prior art, the present invention is directed to the problem of mud yield is big, processing is difficult, and the life that flinty slope is present
The situation of state property difference, to mud added material, prepares the domatic silt soil of softening, soil mud and modified mud and plants raw base material,
Flinty slope is transformed, ecological revetment is built.In addition, the simple environmental protection of engineering construction of the present invention, there is good economy
Value and social value.
