Description
Technical Field
The invention relates to the technical field of sand prevention and fixation, in particular to an ecological sand prevention component.
Background
With the rapid development of economic construction in western regions of China, the construction of infrastructures such as railway, highway and city development is widely developed in northwest deserts, Gobi and other regions of China. And the sand storm has serious dangers to roads and sites, if necessary protective measures are not taken, infrastructures such as the roads and the sites can be seriously damaged, and even the safe operation of other infrastructures can be influenced. At present, the existing engineering sand prevention and control measures mainly comprise sand fixation measures and sand blocking measures, including a concrete sand retaining wall, a high-rise PE net sand barrier, a reed sand retaining fence and the like, and the sand prevention measures play a certain role in existing wind and sand disaster prevention and control projects such as roads, fields and the like, but the problems of high construction difficulty, high manufacturing cost, low sand prevention benefit and the like generally exist. Especially when sand prevention is carried out in big wind areas such as a Bailey wind area, a smoke pier wind area and the like, the sand prevention measures of the common structure have poor durability and stability, and other sand blocking facilities with strong durability and stable structure have the problems of high cost and the like, so that the sand prevention method cannot be popularized in a large area.
At present, materials for curing sand prevention in desert areas are extremely limited, most of the materials for curing sand prevention are cement concrete and mortar, wherein cement can consume a large amount of raw materials such as limestone and the like in the production process, a large amount of carbon dioxide can be generated, global warming is accelerated, heavy metals existing in a cement-based solidified body system can generate uncontrollable influence on the performance of slurry, such as normal coagulation and the like of the slurry, and as a common sealing material, the cement solidified body also has the defects of large capacity increase (about 1.5-2 times), poor long-term stability, high risk of secondary pollution of fly ash and the like, so that the cement solidified body can not meet the requirements of large, long-term, stable and low-cost application of the cured sand prevention materials in desert areas.
The ecological restoration measures such as sand blocking walls, sand blocking nets and the like are formed through measures such as planting trees, planting grass and the like, however, the ecological measures are implemented to cause sand prevention difficulty due to the fact that the ecological environment of a desert area is severe and the survival rate of plants is extremely low, and the limiting factors of the ecological measures are mainly that the rainfall amount of the desert area is small, the evaporation amount is large, and the water loss is fast, so that the sand prevention and control effect by directly planting green plants in the desert area is not ideal.
Disclosure of Invention

The geopolymer solidified material has excellent mechanical performance, acid and alkali resistance, fire resistance and high temperature resistance, has the characteristics of capability of replacing common portland cement and capability of utilizing mineral waste and construction waste as raw materials, and adopts waste incineration fly ash as a base material.
The ecological sand-proof member comprises a curing body and fillers embedded in the curing body, and can realize an effective sand blocking effect (capable of ventilating and blocking dust and sand) through the change of different curing body shapes and arrangement matrixes, wherein the curing body of the ecological sand-proof member is formed by pouring a fly ash base polymerization curing material, so that the stable curing of pollutants such as heavy metal, dioxin and the like in fly ash can be realized, and the curing body can be ensured to have the characteristics of corrosion resistance and high compressive strength on the premise of ensuring the environmental safety, the weather resistance and the stability of the curing body in a sand area are ensured, and the curing body is not damaged along with the influence of the external severe environment;
in addition, the filler mainly formed by modified sludge is embedded in the solidified body, so that higher water retention and high organic matter can be provided for the growth of plants, the filler can meet the growth of drought-resistant grass seeds and plants, and the root system of the plant is promoted to penetrate through the filler to tie the root and sand, so that good sand prevention and fixation effects are achieved. The filler can be combined with a fly ash base polymerization curing material to jointly construct a special composite sand blocking material which is corrosion-resistant, strong in durability and capable of combining physical sand blocking with ecological sand blocking.
Therefore, the ecological sand prevention component comprehensively utilizes a large amount of solid waste and sludge, not only realizes resource utilization of urban solid waste, but also combines physical sand blocking with ecological sand blocking, and realizes a new ecological sand blocking idea.
As a practical manner, the cured body has a rectangular or semicircular shape.
As a practical mode, the fly ash base polymerization solidified material comprises the following raw materials in parts by weight:
20-60 parts of incineration fly ash, 10-40 parts of coal gangue, 10-30 parts of composite modifier and 10-40 parts of solvent.
The fly ash base polymerization curing material provided by the invention utilizes a large amount of solid waste (coal gangue) and hazardous waste (fly ash) as main raw materials, the composite additive is added according to the proportion to form slurry, and the slurry can be poured into curing bodies with different physical shapes through a mould, so that the fly ash base polymerization curing material has the advantages of high curing speed, high strength after curing, convenience for construction and modeling, strong corrosion resistance, high environmental protection value, good social benefit and the like compared with cement or concrete, does not need any maintenance after construction, has the same hardness, durability and thermal stability as natural rock after molding, has a service life of more than one hundred years, is proved by experience, can be dried at 20 ℃ for 2 hours, can be completely dried at 48 hours, can increase the strength of 96 hours to 10MPa, and can reach the final curing strength of more than 20 MPa.

At present, incineration fly ash is listed as hazardous waste, and an effective recycling treatment mode is not available, so that harmless recycling treatment of the incineration fly ash is an urgent problem.
The coal gangue is a solid waste discharged in the coal mining process and the coal washing process, and is a solid waste mixed with coal in the coal forming processA layer-associated, less carbonaceous, black-gray rock that is harder than coal. Comprises tunneling waste rocks in the tunneling process of a roadway, waste rocks extracted from a top plate, a bottom plate and an interlayer in the mining process, and washing waste rocks extracted in the coal washing process. The main components of the material are Al2O3 and SiO2, and the material also contains Fe2O3, CaO, MgO and Na in different quantities2O、K2O、P2O5、SO3And trace rare elements (gallium, vanadium, titanium, cobalt). The annual output of general industrial solid wastes such as tailings, coal gangue, fly ash and the like in China is more than 13 hundred million tons, the comprehensive utilization rate is only 55 percent, the annual output of the coal gangue serving as second large solid wastes is about 4 hundred million tons, the comprehensive utilization rate is only 58 percent, and the accumulated large amount of coal gangue not only pollutes the local environment, but also is a serious waste of resources.
As a practical mode, the composite modifier comprises the following components in a mass ratio of 40-60: 5-15: 5-20: 5-10 parts of metakaolin, silicon powder, sodium silicate and sodium hydroxide. .
Metakaolin (MK) is kaolin (Al)2O3·2SiO2·2H2O, AS for short2H2) Anhydrous aluminium silicate (Al) formed by dehydration at a proper temperature (600-900 ℃) as a raw material2O3·2SiO2Abbreviated AS2). Kaolin undergoes several structural changes when heated in air, and when heated to about 600 ℃, the layered structure of kaolin is broken down by dehydration to form transition phase-metakaolin having poor crystallinity. Because the molecular arrangement of metakaolin is irregular, the metakaolin is in a thermodynamic metastable state and has gelling property under proper excitation. Metakaolin is a high-activity mineral admixture, is amorphous aluminum silicate formed by low-temperature calcination of superfine kaolin, has high pozzolanic activity, and is used for manufacturing high-performance geopolymers in the application.
Silicon powder (Microsilica or silicon Fume), also called Microsilica, is known as "Silica Fume", and is produced by collecting and treating smoke and dust escaping with waste gas in the process of smelting industrial silicon and ferrosilicon at high temperature in an industrial electric furnace by a special collecting device. The silicon powder is high in the industrial electric furnaceDuring the process of warm smelting of industrial silicon and ferrosilicon, the smoke escaping with the waste gas is collected and treated by a special collecting device. In the escaping soot, SiO2The content of the smoke dust is about 90 percent of the total content of the smoke dust, the granularity is very small, and the average granularity is nearly nano level, so the smoke dust is called as silicon powder.
The melting point of sodium silicate is about 45 ℃, and the sodium silicate is soluble in water and alkali solution and insoluble in alcohol and acid. The water solution of sodium silicate is commonly called water glass, the sodium silicate is colorless and slightly colored transparent or semitransparent viscous liquid in a system taking water as a dispersing agent, and the solid sodium silicate is colorless and slightly colored transparent or semitransparent glass block-shaped body. The form of the material is divided into three types of liquid, solid and water quenching, and the material is called colloid theoretically.
The chemical formula of sodium hydroxide is NaOH, commonly called caustic soda, caustic soda and caustic soda, is strong alkali with strong corrosivity, is generally in a sheet or particle form, is easy to dissolve in water (release heat when dissolved in water) and form an alkaline solution, has deliquescence, and is easy to absorb water vapor (deliquescence) and carbon dioxide (deterioration) in air. The sodium hydroxide is colorless transparent crystal with density of 2.130g/cm3Melting point 318.4 deg.C, boiling point 1390 deg.C, soluble in ethanol and glycerol, and insoluble in propanol and diethyl ether.
As a practical way, the solvent is water and/or landfill leachate.
The landfill leachate is high-concentration organic wastewater which is formed by deducting the saturated water holding capacity of garbage and a soil covering layer from water contained in the garbage in a garbage landfill, rain, snow and water entering the landfill and other water and passing through the garbage layer and the soil covering layer. There is also moisture that accumulates to leak out of the waste ready for incineration.
As a practical manner, the method for producing the cured body includes the steps of:
s1, mixing the metakaolin, the silicon powder, the sodium silicate and the sodium hydroxide according to the proportion to obtain the composite modifier;
s2, mixing the composite modifier obtained in the step S1 with the incineration fly ash and the coal gangue in parts by weight, adding the solvent in parts by weight, and stirring to obtain a slurry-shaped solidified body;
and S3, adding the slurry-shaped solidified body into a mould for pouring and forming to obtain the solidified body.
As a practical mode, the modified sludge comprises the following raw materials in parts by weight:
100-400 parts of oven-dried sludge, 10-20 parts of aeolian sand, 20-40 parts of bentonite and/or kaolin and 0.1-0.5 part of sodium carbonate and/or sodium bicarbonate.
Wind-blown sand refers to a layer of sand blown and deposited by wind. The aeolian sand is mostly seen in deserts and gobi, the grain diameter of the aeolian sand is mainly distributed between 0.074mm and 0.250mm, the content is more than 90 percent, few particles larger than 0.25mm are only 0.1 percent, and less than 9 percent of particles smaller than 0.074mm are also present, and the nonuniform coefficient is about 1.35. The aeolian sand has the advantages of low content of powder sticky particles, low surface activity, looseness, no aggregation and obvious non-plasticity, the particles belong to fine sand, and the sand particles are composed of natural poor grading. For aeolian sand with extremely poor grading and no cohesiveness, the forming is difficult, and the shearing resistance after forming is also poor. The surface of the sand has almost no physical adsorption to water, and the maximum water absorption is less than 1%, and is generally near 0.
The bentonite is a non-metal mineral product with montmorillonite as a main mineral component, is also called bentonite, bentonite or bentonite rock, the content of the montmorillonite in the bentonite is 85-90%, the main chemical components of the bentonite are silicon dioxide, aluminum oxide and water, and the bentonite also contains elements such as iron, magnesium, calcium, sodium, potassium and the like.
Kaolin is a non-metal mineral product, is a clay and clay rock mainly containing kaolinite clay minerals, and its mineral components mainly comprise kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals.
Sodium carbonate (Na)2CO3) Molecular weight 105.99. The purity of chemicals is more than 99.5% (mass fraction), which is called soda ash, but the classification belongs to salt and not to alkali. Also known as soda or soda ash in international trade. Sodium carbonate is a white powder that is readily soluble in water, and the solution is alkaline (which causes the phenolphthalein solution to turn pale red).Can be decomposed at high temperature, and can not be decomposed by heating.
Sodium Bicarbonate (Sodium Bicarbonate), commonly known as "baking soda", "soda ash" or "bicarbon", is a white fine crystal with a solubility in water lower than that of Sodium carbonate. The solid starts to be gradually decomposed at a temperature of more than 50 ℃ to generate sodium carbonate, carbon dioxide and water, and is completely decomposed at a temperature of 440 ℃. Sodium bicarbonate is an acid salt generated by neutralizing a strong base and a weak acid, and is weakly alkaline when dissolved in water.
As a practical mode, the absolutely dry sludge is taken from municipal sludge or sludge after composting and fermentation decomposition.
As a practical mode, the water content of the sludge after the composting fermentation and decomposition is 38-42 wt%, and the water content of the municipal sludge is 78-82 wt%.
As an implementable step, the preparation method of the modified sludge comprises the step of mixing and stirring the oven-dried sludge, the aeolian sand, the bentonite and/or the kaolin, and the sodium carbonate and/or the sodium bicarbonate in parts by weight.
