Description

1359703 六的发明说明: Technical Field of the Invention The present invention relates to a method for manufacturing a hydraulic retaining layer. The screening refers to the use of a reservoir in mud to construct, for example, a wave block, a shaped block, a slope revetment, A method for manufacturing a hydraulic retaining layer of a hydraulic sheath structure such as a stone material, a house, a water permeable frame, or the like. [Prior Art] In the known art, for example, a hydraulic sheath structure such as a wave block, a shaped block or the like is usually required to use a large amount of cement as a cement when it is manufactured. When the main structure is manufactured, it will cause environmental problems such as damage to the ecological environment, failure to recycle and reuse. In order to improve the above defects, the applicant has proposed the invention patent No. 1241223, which is mainly used to add active minerals containing aluminum and lanthanum monomers in soils containing aluminum and strontium. When the soil is a clay containing hydrogen bonds, due to the poor structural strength of the hydrogen bond, it is necessary to carry out a high-temperature calcination step to remove hydrogen bonds, and then dissociate the aluminum and bismuth monomers in the soil and the active mineral with a strong alkali. The aluminum and ruthenium monomers are re-polymerized into a hydraulic bauxite having a xenon tetrahedron and an aluminoxytetrahedron using a polymerization medium such as sodium citrate and/or potassium citrate. The structure constructed by such hydraulic retaining soil is not only in accordance with the requirements of the Water Resources Department for the compressive strength of general concrete, but also suitable for reuse. In addition to the above-mentioned invention patent, it is possible to manufacture a social material suitable as a hydraulic protective layer, and it is also possible to improve the environmental protection problem derived from the use of cement as a main component. However, in the invention patent, for the clay soil containing hydrogen bonds, 3 1359703 must use high temperature calcination to improve the structural strength, but from the perspective of environmental protection, high temperature calcination requires a large amount of Fuels such as electricity, coal or oil will also generate a large amount of carbon dioxide when burned. Therefore, not only the economic benefits are not good, but also the new environmental protection requirements for energy conservation and carbon reduction. Therefore, if the applicant's certificate number "1241223" is used for the invention patent, if the reservoir sludge containing more hydrogen bonds is used as the soil material, it is impossible to fully consider the environmental protection requirements of energy conservation and carbon reduction. However, as far as the Taiwan region is concerned, many rivers are mostly in the form of short and steep slopes. The geological regions through which water flows are mostly soft shale-like clays. After many large hillsides have been developed, the rainwater is easily entrained. The muddy sand flows into the river and is deposited in the reservoir. This situation not only causes the effective storage capacity of the reservoir to decrease year by year, but also affects the service life of the reservoir. Therefore, how to remove the reservoir sludge to improve the effective water storage capacity of the reservoir has been It is an important part of water-library management. ν However, there are currently three types of treatments for reservoir sludge in Taiwan. One is to use mechanical equipment to excavate the silt, and then select the low-lying area near the reservoir to bury the sludge. However, because Taiwan is narrow and thick, it is necessary to find φ. Appropriate landfill sites are not easy. Therefore, the treatment unit does not surround the farmland with mud everywhere, which is the dilemma of nowhere to be buried. The second treatment method is to discharge the muddy sand deposited at the bottom of the reservoir to the lower reaches of the river by hydraulic means, which will lead to the problem of the downstream river channel gradually shrinking. The third method is to use high-temperature calcination to make the reservoir sludge into building materials such as lightweight aggregates. This method produces a large amount of carbon dioxide due to calcination, and the cost of calcination is also high. Therefore, this method is neither It meets the environmental protection requirement 4 1359703, and it is difficult to commercialize because the cost is too high. Exploring the system, the general reservoir (4) often faces the thorny treatment from: the use of the reservoir in the mud is limited, and the known places: the rational way to ^ high temperature calcination, will be derived from the high cost of treatment. The present invention is directed to the study of reservoirs in mud. It is possible to make the reservoirs with limited use in the mud under the environmental protection demand of energy conservation and carbon saving by the formulation and the matching between the steps.

It can be used as a material for hydraulic sheath structures to improve the environmental problems caused by the disposal of mud at the reservoir age. SUMMARY OF THE INVENTION The object of the present invention is to provide a hydraulic retaining layer of soil that utilizes the strength of the reservoir in accordance with the requirements of Ab 诙伢 在 在 减 减 减 减 减 减 减 减 减 减 减 减 减 减 有效 有效 有效 有效 有效Production method. The manufacturing method of the hydraulic retaining layer of the present invention comprises the following steps:

Disposal of the reservoir in the mud: grinding the dry mud from the reservoir into a powder; arranging the sandy soil: mixing the mud and sand of the reservoir into a sandy soil, the sandy soil containing 5 to 50% by weight of the reservoir Adding active minerals: adding active minerals to sandy soils to make SiO2 + AI2O3 + CaO > 80% in soil; and cracking and polymerization: using strong and polymeric media to cleave the inscriptions in the soil , ϋ re-polymerized into a soil and soil layer with a Shihe oxygen tetrahedron and a Ming tetrahedron. The above-mentioned hydraulic retaining layer soil can be made into, for example, a wave-blocking block, a shaped block, a slope revetment, a stone material, a house structure, a water-permeable frame, and the like, and a water-repellent layer structure suitable for the water side, according to the use. For the hydraulics, use 5 1359703 to protect the soil as long as the appropriate water is added to the mud, and then the mud is poured into the sheath structure with the mold. The mud, sand and other soils according to the present invention are classified according to the soil uniform classification method and the ASTM D653 classification method, that is, when the soil particle size is 2.75 mm (5 mm mesh), it belongs to gravel, and the particle size is 4.75. Mm ~ mesh hole) belongs to sand young (10), particle size between 75~5 # m belongs to silt (10) t), particle size is <5# m belongs to clay (seven) 叮). According to the foregoing classification method, it is detected that the reservoir sludge used in the present invention belongs to the particle size of the sludge and clay, which is a low-plastic inorganic clay (referred to as CL) according to the unified soil classification method. The sand used in the present invention belongs to sandy soil (referred to as SP) according to the unified soil classification method, and the inorganic clay sand soil (referred to as SC) can be obtained after the reservoir is mixed with mud and sand. In the step of "treating the reservoir age mud", the present invention firstly removes the muddy sand from the sedimentation tank of the reservoir and forms a mass of dry mud ghosts in order to make the reservoir in the mud in the subsequent cracking step. For the sake of smoothness, it is preferred to test the composition of the powdered mud after grinding the dry mud with a powder having a diameter smaller than that of the powder 4, as a reference value for the addition of the "active mineral". The purpose of the present invention for blending sandy soil is to weaken the hydrogen bond strength of the reservoir in the mud, so that the prepared sandy soil does not need to be subjected to high temperature calcination, and at the same time, the finished structure can reach the specified compressive strength. In order to achieve the project, the reservoir of the sand soil of the present invention is preferably 5 to 5 wt% in the mud content, and when the content of the water sludge in the sandy soil is less than 5 wt%, The water is cheaper: there are too few silt in the mud, and the mud is not in line with economic benefits, and the content of the reservoir in the mud is higher than that of the county. / When the door is 50% by weight, the combined strength of the structure is not ideal and it lacks economic benefits. Further, the sand added in the step of "adjusting; sand-mixing soil" of the present invention is not particularly limited: in the present invention, general river sand or sea sand can be used. The active mineral used in the present invention refers to a substance containing high silica dioxide (si02) and aluminum oxide (Α1ζ〇3), and specific examples thereof include fly ash, hearth stone, zeolite, ash, etc. The addition of active minerals supplements the deficiency of aluminum and barium in sandy soils. The addition amount of the above-mentioned active minerals is based on the content of the tested muds in the mud and the contents of the shixi monomer. In order to make the obtained structure conform to the regulations of the Water Resources Department on the compressive strength of concrete, the sand property after adding the active minerals The content of SiO 2 + Al 203 + Ca 0 in the soil is preferably more than 80% by weight, that is, according to the test results, the above three components are related to the compressive strength of the structure, so that only two or two of them are used. When the above components are more than 80% by weight, a structure conforming to the compressive strength specification can be obtained. Tt. The cracking and polymerization steps of the present invention mainly utilize a strong base to crack the ruthenium monomer and the aluminum monomer in the soil, specifically, such as sodium hydroxide (Na〇H), which is shown in the experiment, in order to obtain better The cracking effect, the concentration of the strong base is preferably 8~16M. The present invention uses a polymerization medium to re-polymerize the cracked ruthenium monomer and aluminum monomer to form an inorganic hydraulic retaining layer similar to a zeolite structure. In order to achieve the above object, the polymerization medium used in the present invention has a remark For example, it may be water glass. In the present invention, the so-called water glass g is a glass-like melt of an alkali metal silicate. It is light green, colored or gray with both The color of the water, according to the difference of the metal oxides, the water glass mainly has

The polymerization of the glass of the saliva can be re-polymerized into an inorganic hydraulic layer of a similar structure, and the basic structure of the above-mentioned zeolite-like layer is the Shihe oxygen tetrahedron and the Ming oxygen tetrahedron. Since the present invention is cracked and = new polymer f monomer and material body, the number of the certificate number "mm3" has been detailed in the previous article, and will not be described here. The beneficial effects of the invention are as follows: by formulating the mud and sand of the reservoir into a sandy soil which does not require high-temperature calcination, and simultaneously adding a suitable active mineral to the sandy soil, the step of cracking polymerization can not only produce a strong I A structure that meets the standards of the Water Resources Department. This manufacturing method can use a large amount of reservoir sludge to increase the utilization efficiency of the reservoir sludge. Since the method does not require high-temperature silver burning, the manufacturer has energy saving and carbon saving. The effect outside can also improve the environmental problems of the reservoir silt being randomly discarded due to limited use.
