Description

1241223 IX. Description of the invention: [Technical field to which the invention belongs], the present invention relates to a manufacturing method and a regeneration method, in particular, a protective cover soil made of ^ is suitable for constructing wave-cutting blocks, special-shaped blocks, edges Method for manufacturing hydraulic protective soil for slope protection, such as stone hopper houses, permeable grids, and the like, and when such protective structures are discarded, and a method for recycling. [Prior art] In the known art, in order to resist the waves invading the coast, Sun usually arranges them according to different construction methods, and places such as: wave-cutting blocks, special-shaped blocks, etc. for hydraulic use, and D structures are placed in the vicinity. The location of the coast is used to protect the safety of the coast and the land. However, in the manufacture of conventional protective structures for hydraulic engineering, it is usually necessary to make the cement and slabs as cementing materials. However, cement and cement River sand and gravel-based structures will have the following defects in manufacturing: 1. Cement production will produce a large amount of carbon dioxide that damages the environment. Therefore, the use of cement in Dali will indirectly damage the environment and ecology. D 丨 V 疋 is located in the river bed ±, and can protect the river bed from excessive natural stone washed by the river. However, the protective structure such as the traditional wave-blocking block uses river: stone as the main material, which will cause excessive sand and stone. Mining or stolen mining will make the Tsai River Bed unprotected and endanger the safety of flood control structures or river crossing structures. 2. Known structures such as wave-cutting blocks are a kind of impervious concrete block after molding. The color of this concrete is different from the original color of the coast, so it will seriously damage the landscape of the coast. Said 1241223 Fourth, the more important—the concrete blocks made of sandstone and cement are beneficially recycled and cannot be decomposed by nature, so #structural blocks and other structures are discarded or washed by the waves to the bottom, Will cause permanent pollution of the environment and marine ecology. In addition, a kind of known hydraulic protective cover structure uses soil cement as raw material. The construction method is to mix the soil and cement, and then use a roller to roll the soil cement to the required density and Strength to form, for example, a river bank protection bank structure. Although this construction method is possible, free / useable; 丨 / stone, but during construction, it requires tedious material preparation, rolling procedures, and guarding space. The problem is that the compressive strength after rolling is large, and the “spoon” has reached below 1G MPa (mega_paseal), and the compressive strength is insufficient. In addition, although this construction method uses soil as the main material, the soil particles pass through After compaction, it will be connected to cement, so this kind of structure composed of soil and cement is impervious to water; it cannot be used as a source of water. Therefore, it is necessary to look for alternative materials such as wave-blocking structures for hydraulic protective structures. At the same time, it can meet the requirements of sufficient compressive strength and so on. A. The problem of urgently improving the manufacture of protective structures for plumbing. [Summary of the invention] The purpose of the present invention is to provide a method that can be produced. High-degree, water-permeable structures, such as ri & 4 and ^, and distant, '. Structures can be recycled and reused for manufacturing hydraulic protective soil. A protective cover constructed by another objective of the present invention The purpose of the layered structure is to provide a recycling method capable of recovering and reusing the cover soil for hydraulic engineering. 1241223 The method for manufacturing the cover soil for hydraulic engineering according to the present invention includes the following steps. Syria ..., take the soil of "aluminum alloy" and silicon (Si) as the spare. ^ First, the temperature of the material should be advanced and calcined to destroy the bond of the aluminum lice [Ai (OH) 3] in the soil. The helmet sentenced Fang Lierren ^ to make the soil 壌 form stable m 吕 compounds, and when the soil is hydrogen-free sand, it can be used directly. Add the appropriate amount of active mineral monomers to the soil according to the content of the monomers in the soil. Shao in the supplementary soil of j system (3) Strong test cracking: Use strong test to dissociate Shao in the soil and active minerals. Flat basket (4) Polymerization: Re-polymerize the core material that has been strongly disaggregated with a polymerization medium: a hydraulic protective soil with a silicon latex tetrahedron and an aluminum-oxygen tetrahedron. I. The cover soil for hydraulic engineering can be made into, for example, wave-cutting blocks, special-shaped blocks, bank protection for slopes, stone U housing structures, and permeable grid structures. When it is made, it is washed and placed into a protective structure in hydraulic engineering. The recycling method of the present invention is to recover the aforementioned protective cover structure into a recycled protective cover soil which can be re-used and reused. The recycling method includes the following steps: The product made by the above manufacturing method "is broken into small clods. Grind with U 冓 only: Use a grinder to grind small clods into reclaimed soil. (2) Adding active minerals: The content of Shao and Shixi monomers in the soil regenerated by the medium is 1241223, and an appropriate amount of active minerals and silicon monomers are added to the soil. Aluminum in filled soil (4) Strong base cracking: Use strong base to dissociate regenerated soil and monomers. The polymerization media of aluminum and stone in the wide-area f will be “reconstructed, cut, cut, and regenerated cover soils with silicon-oxygen tetrahedron and aluminum-oxygen tetrahedrons. Layer structure. Re-humans are washed into a regenerative protective shell. The protective layer structure for hydraulic engineering is passed as ffl + Coastal Washing ... The 偁 偁 system is. It can be used to slow down the wave's scouring force. The wave-blocking block, the other side of the mountain sincerely loves mountain fighting, + ”The force J horse is built near the banks of the river. It is stone, a permeable grid, or a building or material near / maternal or edging. The soil used in the invention is classified according to the astm method. The above-mentioned soils can be divided into two types:

-C ^ OC-OM ^ OW-OM ^ ow-oc ^ OP G 'GM quality soil (sw, SP, sm, sc, scsmGP-GM, GP_GC) 1 sP-SM.SP-sc), # if ^ f ; M'SW-SM'SW-s-H clay soil (CL, paper, 0L, heart Γ 0H, CL_ML, Pt). Among them, G represents dish soil, S: sandy soil, M represents inorganic silt soil, c represents Wuqing soil, 0 === soil, surface peat soil, " represents good gradation ~ represents poor gradation, and L represents Low plasticity, Η represents high plasticity. According to the present invention, different treatments of the soil M _ i are used. When the soil yields poorly depending on the _ structure of the soil, Rufu, 7: ,, and bond clay, the hydrogen bonding is not ruled out. Not only will it affect the molding. The resistance of the structure to 1241223 dust and the presence of hydrogen bonds will also absorb a large amount of water during molding, resulting in shrinkage cracks in the structure after molding, which affects the quality of construction. In order to avoid the above defects, when using clay as soil In the present invention, the clay mineral needs to be heated to 700V and maintained at 7 ° C for 4 hours. The purpose is to destroy the hydrogen bond of aluminum hydroxide [A1 (0H) 3] in the soil, so that the soil forms amorphous broken oxygen compounds.活性 The active mineral used in the present invention refers to an active mineral containing high-dioxide state office) and alumina (Al203), and specific examples include fly ash, furnace slag, and zeolite. , Silica ash (training "e", etc.) can supplement the deficiency of aluminum and silicon in the soil by the addition of active minerals. The strong depolymerization step of the present invention mainly uses 5 ~ Satoshi's aerosol ( NaOH) solution, and dissociate the soil and active minerals after high temperature treatment into second monomers and materials. The purpose of dissolution is to enable the polymerization step to proceed smoothly. Krypton or potassium oxalate (K2Si04) 'repolymerizes the osmium and ming monomers in the mineral after strong base depolymerization into an inorganic hydraulic protective layer i with a vermiculite-like structure. The basic structure of oxygen tetrahedron and oxygen tetrahedron, the connection of each tetrahedron is mainly based on ionic and covalent bonds, with arm watt bonds (van der Waals bond) as the auxiliary. This type of ionic and covalent bonds The main feature of the 2 protective soil is the type of bond relationship between monomers. Metal-like 'so it can produce better structural strength, and the ratio of the material of the protective soil for hydraulic engineering is different.' The bonded structure can be roughly divided into the following four types. (A) the first type: Si : A1 = 1, (m), the three-dimensional structural formula is as shown below I241223:

The structure is shown below

(<) The third type: Si: A1 = 3, do, the three-dimensional structural formula is as follows:

The three-dimensional structural formula is as follows: (4) Type 4: Si: Al > 3,

〇 That is, if the ratio of the hydraulic protective soil after depolymerization and repolymerization is approximately equal to 1, the molecular structure of the protective soil

When the ratio between the number of μ and the number of the two is approximately 2, its molecular structure is ^, and the first type is similar to the second 10 1241223 type, and so on. When the quantity ratio of silicon and aluminum is 3 It belongs to the second type, and when the ratio of the two is greater than 3, the molecular structure is similar to that of the fourth type. In order to form, for example: a wave-blocking block, a shaped block, a sloping block, a τ-biting anti-slab, a stone material, a house structure, a permeable grid, etc., the present invention needs to be in the aforementioned covering soil. Add an appropriate proportion of water to remove the slurry that is ready to be used to form the structure. According to the test results, it is known that the mud destruction preferably contains: 25 to 50% by weight of soil, 25 to 50% by weight of active minerals, 20 to 35% by weight of water, 5 to 10% by weight of a polymerization medium, and A small amount of gas content. The mud prepared in this proportion will have good compressive strength and water permeability when forming a protective layer structure. The regeneration method of the present invention is mainly used to recover the hydraulic protective cover structure manufactured according to the above manufacturing method, and the protective cover structure is made into a renewable protective cover soil. The regeneration method firstly converts the structure The material is dismantled, and then the structure is crushed into small soil pieces, and then a grinder with a steel ball with a diameter of 50 to 80 mm is used to grind the powder with a particle size of less than 0.2 mm to form regenerated soil. The above-mentioned regenerated soil can be made into the reclaimed protective soil of the present invention through the steps of high-temperature calcination, addition of active minerals, and strong disintegration to combine. The reclaimed soil can be re-cast into a reclaimed protective structure after adding water . [Embodiment] [Embodiment 1] Referring to FIG. 1 and the schematic diagram of the production process of Annex I, the composition of embodiment j of the present invention is shown in Table 1, that is, 1000 parts by weight of fly ash is added to 10,000 weight ~ In the burned soil, parts by weight of sodium hydroxide depolymerized the fly ash and the soil, and then 120 parts by weight of sodium silicate 1241223 (NaJiO2) was used to polymerize the depolymerized mixture. I "form the present invention The required protective soil for hydraulic engineering is added with 900 parts by weight of water to the protective soil to form a slurry, and the slurry is poured into, for example, shaped blocks of wave-cutting blocks, slope protection, and stone materials , Housing structure, permeable grid, etc. The composition of fly ash and soil in Table i is shown in Table 2, and the composition of sodium oxalate contains: 14.7% Na2O, 29.5% SiO2_2), and 55 8% water. The performance test of compressive strength, porosity and permeability coefficient of this protective structure is shown in Table 3. [Examples 2 to 10] The manufacturing steps are as shown in Example 1. The difference lies in the soil, the proportion of active minerals, and the components. The soils in Examples 9 to 10 are made of nitrogen and non-calcined sandstone. The performance test of the formed structure is shown in Table 3. [Embodiment 11] Read more about the regeneration flow chart in Figure 2 and Appendix 1. The soil in Embodiment 11 of the present invention uses recycled soil, that is, after dismantling the protective cover structure, it is compacted into a small soil mass with steel balls of 5G ~ 8Gmm. Grinding machine, grind small soil pieces into regenerated soil less than 0.2mm and calcined at high temperature, and then mix the reclaimed soil after calcination ^ calcined fly ash, and by weight of deleted ammonia Sodium oxide undergoes depolymerization 'Polymerization of 120 parts by weight of Shi Xier II. I can form a reclaimed protective soil. Adding to this protective soil, the shape-reading water is prepared into loach' to form regenerated water jade. The performance test of the structure formed by the sheath structure is also shown in Table 3. [Examples 12 to 16] The manufacturing steps are as shown in Example 11. The difference is that after calcination 12 1241223 raw soil, active mineral ratio and composition, performance tests are also shown in Table 3. It can be known from the above description that the compressive strength of each embodiment of the present invention is greater than 20 MPa at 28 days, and the compressive strength at 90 days is approximately equivalent to 28 days, and the compressive strength at 7 days is approximately 7 times the compressive strength at 28 days. 〇 ~~, the above compressive strengths are higher than the current compressive strength requirements of the construction unit for the hydraulic protection structure. For example, the current general construction units require the compressive strength of the concrete at 28 days. It needs to be greater than 175 ~ 21〇, and lMPa = 10.2 kgf / cm2, so the compressive strength of the aforementioned standard can be converted into 17.16 ~ 20.6MPa, and the compressive strength of each embodiment of the present invention is higher than this standard value. More specifically, Example 9 and 1G of the present invention directly use unscented silver-fired sand. These examples have a resistance of greater than 20 MPa at 28 & The soil's compressive strength is also obviously improved: many, so the hydraulic vine soil made by the manufacturing method and the regeneration method of the present invention can construct a working layer structure with better compressive strength. It can also be understood from the data in Tables 3 and 4 that the water permeability coefficient of each embodiment of the present invention in the water permeability test after 9G days is approximately i05 ~ i07. This water permeability coefficient is similar to silty clay. Equivalent, it is a water-permeable material. Since the protective layer structure of 2 Ming is used on the coast or river bank, a good layer of soil can retain the original porosity of the soil, that is, the characteristics of the protective structure of the present invention: Similar to natural stones, it can be invented when in use: However, the use of 'integration into one' will not destroy the ecology. Of course, Ben Zhengyou said ,,,,. The structure can be recycled and reused, so as to solve the pollution caused to the environment by Bai Zhi's hydraulic protective layer structure with cement as the main source. However, the above are only the preferred embodiments of the present invention, so as to limit the scope of implementation of the present invention, that is, the simple equivalent changes and modifications made according to the present application: All are still within the scope of the invention patent.
