Abstract

The invention discloses a kind of drought resisting artificial side slope soil preparation method against corrosion, the present invention is processed under certain condition using polyvinyl acetate (PVAc) lotion, plant fiber (straw or wheat stalk), non-vegetable soil (raw-soil), organic fertilizer (livestock and poultry dry manure), water, vegetable seeds and is made.High molecular material PVAc used can effectively enhance Soil Anti-erodibility and water holding capacity, and plant fiber can play reinforcement fixation, and to prevent soil slump on abrupt slope, while also side slope soil plays stabilization for connection of the PVAc material between soil particle.The artificial soil of preparation is sprayed onto side slope by hydroseeder, forms certain thickness soil layer, has the ability for preferably resisting water erosion and wind erosion, can be grown for side slope vegetation and be provided good soil environment (water, fertilizer).Artificial soil performance of the invention is stablized, and is not influenced by batch, season, region, and good application effect is able to maintain, and convenient, low in cost, the side slope generated suitable for arid biogeographic zone engineering construction of drawing materials.

Description

A kind of drought resisting artificial side slope soil preparation method against corrosion

Technical field

The invention belongs to field of environmental improvement, and in particular to a kind of artificial soil preparation method of drought resisting against corrosion.

Background technique

With urbanization, it is industrialized quickly propel, all kinds of infrastructure constructions, power station and exploitation of mineral resources intensity Increase, Important Project (such as power station, large-scale road and large-scale mine) will form a series of excavation slope and Dumping Sites, lead Cause the ecosystem impaired.These excavation slopes and Dumping Sites are due to no soil and vegetative coverage, and reparation is very slow naturally, and There are the geological disaster risks such as landslide, mud-rock flow, avalanche, soil erosion.Artificial earthing is quickly and effectively side slope reparation Method, since engineering excavation earthwork is huge, and High aititude mountain area soil is shallow, rare, and transport difficult, Resuming agent is very It is high.The artificial soil of design low cost is the important selection of slope ecological reparation.However, unvegetated soil is highly susceptible to water Erosion and wind erosion destroy, and therefore, the resistance to corrosion and water conservation drought-resistant ability for enhancing soil itself are to reduce slope soil erosion, promote The effective means of vegetation growth.The artificial soil with drought resisting against corrosion is prepared using local common materials, for low cost and is had Effect, environmentally friendly impaired slope ecological reparation have important value.

Summary of the invention

Above-mentioned background technique there are aiming at the problem that, the present invention is intended to provide a kind of preparation of drought resisting artificial side slope soil against corrosion Method.

For this purpose, the invention adopts the following technical scheme: a kind of drought resisting artificial side slope soil preparation method against corrosion, including it is following Step,

Step 1, stalk (straw or wheat stalk) is cut into the stalk section of 5~20cm long；

Step 2, gathering project is excavated into the non-vegetable soil generated and crosses 2cm sieve, filter out the ingredient that partial size is less than 2cm；

Step 3, the stalk section that step 1 prepares and the soil that step 2 is screened are mixed with livestock and poultry dry manure, shrub vegetable seeds Conjunction stirs evenly, and accounting for gross mass percentage is (5%~20%): (50%~70%): (5%~30%): (0.1%~ 5%)；

Step 4, polyvinyl acetate is dissolved in water with the concentration that mass percent is 2~5%, dilutes, stirs evenly；

Step 5, the polyvinyl acetate cream after 10%~30% step 4 dilution is added in step 3 gained mixture Liquid；

Step 6, using hydroseeder, the mixture that step 5 is obtained is sprayed onto side slope.

As supplement to above-mentioned technical proposal and perfect, the invention also includes following technical characteristics.

The present invention can achieve it is following the utility model has the advantages that 1. through the invention artificial soil obtained can solve in side slope Soil stability is poor, it is easy to the technical issues of peeling off by water erosion and wind erosion.The artificial soil shearing resistance that the present invention prepares Intensity is larger, and slope stability is preferable, has good resistance water erosion and wind erosion ability；2. Artificial Soil obtained through the invention Earth can solve that side slope soil layer is thin, and soil moisture content is low, the poor technical problem of fertility.The present invention is to the specific retention for improving soil Power greatly facilitates effect for the growth of slope plant and microorganism.The artificial soil that the present invention prepares has good guarantor Outlet capacity and fertility can provide good soil environment basis for vegetation growth；3. the artificial soil that the present invention prepares has good Good freeze proof heat resistance (- 18~60 DEG C), can be suitable for Different climate area；4. it is also possible to play waste The effect utilized: stalk (plant fiber), livestock and poultry dry manure；5.PVAc is can be with the environmental-friendly macromolecule material of natural degradation Material, does not pollute the environment；6. for high gradient slope, Seed spraying technology can overcome artificial earthing difficult, mechanically actuated technique Simply, high-efficient, low in cost.

Specific embodiment

Implementation steps:

1. stalk (straw or wheat stalk) is cut into the stalk section of 5~20cm long；

2. gathering project excavates the non-vegetable soil generated, 2cm sieve is crossed, filters out the ingredient that partial size is less than 2cm.

3. the soil (50%~70%) for stalk section (5%~20%) and step 2 screening that step 1 is prepared and livestock and poultry are dry Excrement (5%~30%), shrub vegetable seeds (0.1%~5%) are mixed evenly；

4. polyvinyl acetate is dissolved in water with 2~5% concentration, dilutes, stir evenly；

5. the venamul after 10%~30% step 4 dilution is added in step 3 gained mixture；

6. using hydroseeder, the mixture that step 5 is obtained is sprayed onto side slope.

Material explanation:

1. polyvinyl acetate (PVAc) lotion, from a wealth of sources and cheap, being can be with the environmental-friendly of natural degradation High molecular material.With good freeze proof heat resistance (- 18~60 DEG C), Different climate area can be suitable for；Soil can be enhanced The shearing strength of earth, is effective against water erosion and wind erosion；This kind of strongly hydrophilic group of-NH2 present in lotion, can also absorb lock Firmly part further prevents the rapid evaporation of moisture to the moisture of air evaporation, therefore further improves the water conservation of lotion Performance；

2. plant fiber mainly includes straw (be suitable for paddy fields) and wheat stalk (suitable for wheat planting district), Reinforcement fixation, at low cost, easily collecting can be played；

3. feces of livestock and poultry is a kind of good Organic Fertilizer Resources, such material cost is low, easily collecting, rich in The nutritional ingredients such as nitrogen, phosphorus, potassium, organic matter also rich in, humus can increase gas permeability, reinforced soil with chesson Water conservation water supply function, promote soil in water, air and heat, the balance of fertilizer, promote the growth and breeding of microorganism, accelerate organic matter The release with nutrient is decomposed, so as to improve soil quality, promotes vegetation growth.

4. non-vegetable soil can be acquired from the waste that engineering excavation goes out on the spot, at low cost, easily collecting.

5. the seed of the present invention selection Indigenous Shrub Species and grass.Indigenous plant is the place of production in locality or originating from local plant Object, this kind of plant undergo very long evolutionary process local, and physiology, heredity, morphological feature and local natural conditions are mutually fitted It answers, is best able to adapt to local habitat conditions.
