Description of the Invention: [Technical Field] The present invention relates to a substrate for injecting a substrate and a method for injecting a ground plate of a cerium oxide particle containing colloidal cerium oxide, in particular, for use in a weak site or prevention Site plating materials and site injection methods for the site improvement of site liquefaction and foundation site reinforcement projects. [Prior Art] Injecting materials into a site where the site is consolidated, such as a weak ground plate, is known as an injection material of the main material of the sulphuric acid soda, and an acidic active citric acid aqueous solution composed of soda ash and acid. An injection material of a main material or an injection material mainly composed of a neutral colloidal dioxide material (Patent Documents 1 and 2).彳 These are the main ingredients that contain many tests or salts. If the content of the test or the more is large, the salt or the salt is freely detached from the solid body during the long period of time: the shrinkage failure of the solid body occurs, and the strength of the solid body is deteriorated. In order to improve such shortcomings, in the past 11 years, it has been proposed to treat the soda by means of a cation exchange resin or an ion exchange membrane, and to remove the liquid of the acidic active material solution in the test of the soda, and to use colloidal silica. The site is filled with human materials (see, for example, Patent Documents 3 to 5). The site injecting material contained in Patent Document 3 is composed of acid strontium and strontium soda, and it is possible to obtain a slight difference in the combination of the ancient electricity and the rolled material, so that the point of the injection material is excellent, but it is difficult. . - "In the case of the site injecting material which is described in the patent document 4, the active material is added to the acidic agent such as inorganic acid or tartaric acid to improve the enthalpy of the active (tetra) acid. Injecting materials, but only extending the gelation time for several days, it is difficult to say that it is easy to operate in the construction site. In addition, there is also a method of adding a test agent to make the gelation time longer and improve the storage stability, but In this method, the slight difference in the blending of the materials makes the fluctuation of the gelation large and practically difficult. The site injecting material described in Patent Document 5 is composed of active tannic acid and scorpion soda (inorganic acid). Or an organic acid such as citric acid or gluconic acid, and only phosphoric acid in the example, and an active aqueous solution of citric acid, which is transported from the manufacturing site (worksite) to the construction site due to the concentration of cerium oxide. The cost becomes expensive, and the problem that it is gelled in a few days and cannot be stored in a large amount in engineering has not been solved. As described above, the use of the site injecting material using active tannic acid is limited to only a part of The two components of colloidal cerium oxide and strontium soda are widely used as the main material for the infusion of the gelling agent. The gelation time of the two components is mainly caused by the soda citrate and the gelling agent. The blending ratio is adjusted as 'gelling agent' using citric acid, sulfuric acid or sodium hydrogen sulfate. The phosphoric acid system has a three-stage pKa value (the logarithm of the reciprocal of the acid dissociation constant, pKal = l. 83 ' pKa2 = 6. 43 , pKa3 = l 1.46) is an acid which is easy to adjust the gelation time. However, there are doubts about the eutrophication caused by the accumulation of phosphorus in lakes or rivers. On the other hand, the pKa2 of sulfuric acid and sodium hydrogen sulfate is 1. 74 is smaller and it is more difficult to adjust the gelation time acid. However, the above colloidal cerium oxide is generally commercially available as a commercial product of the dioxide dioxide, usually for the ion exchange resin by the soda The obtained active citric acid is stabilized by heating or the like to concentrate the concentrated cerium oxide concentration of 2〇~50 201200581% by weight of the product, and the average particle diameter is about 1〇_2〇nm. The colloidal silica stone is used as the main The material of the site is a highly permeable material. In the case of the Japanese Patent Publication No. JP-A No. Hei. No. Hei. [Patent Document 4] Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. Hei. Phosphoric acid, or the composition of the use of the eve, can also easily adjust the gelation time, and the target of the site for injecting the substrate with good permeation or high consolidation strength and the site injection method using the same. [Means for Solving the Problem] The inventors have concentrated on 'solving such problems' and found that colloidal dioxo and soda are used as main materials, and a specific g is used as a gelling agent. With the base material, the gelation time (6) is easy to 'perfect to the ground plate, and the durability and the consolidation strength are high. That is, the present invention relates to a substrate material for a human dish, which is a colloidal state of 201200581 cerium oxide and cinnamic acid soda, containing a mineral acid and an organic acid as a gelling agent, and is at a pH of 25 ° C. In 2~7. More preferably, the logarithmic value (pKa) of the inorganic acid and the reciprocal of the acid dissociation constant at 25t: is a pH buffer solution of the organic acid of 〇~7.〇, and has a buffering effect between pH 2 and 7. The ground plate is filled with the base material. The above inorganic acid is preferably a mixed acid of sulfuric acid, phosphoric acid or sulfuric acid and phosphoric acid. The above organic acid is preferably selected from the group consisting of oxalic acid, maleic acid, tartaric acid, malic acid, citric acid, and lactic acid. Preferably, the α, the preparation, the inorganic acid is sulfuric acid, and the organic acid is oxalic acid or citric acid. Furthermore, the present invention also provides a method for injecting the above-mentioned site for injecting the substrate material into the ground. [Effect of the Invention] According to the present invention, it is easy to adjust the gelation time, and the base material for the site for injecting the ground is excellent in durability and high in consolidation strength. By injecting the substrate material for injecting the ground of the present invention into the ground plate, the stability of the ground plate can be remarkably improved. Hereinafter, the present invention will be described in detail with reference to preferred embodiments thereof. The colloidal dioxin of the main material for the substrate for injecting the substrate of the present invention is not particularly limited. A commercially available product can be used. Further, the second main succinic soda is not particularly limited, and a commercially available product can be used. 201200581 The base material for in-situ injection of the present invention contains a mineral acid and an organic acid as a gelling agent. The inorganic acid ' is preferably a mixed acid of sulfuric acid, phosphoric acid or sulfuric acid and glacial acid, and such an acidic salt can also be used. A strong acid such as hydrochloric acid or nitric acid which is completely dissociable is difficult to adjust the gelation time. The concentration of phosphoric acid in the ground material for the ground plate is preferably 0.4 mol / liter or less, in the case of using a mixed acid of sulfuric acid and phosphoric acid as the inorganic acid. The organic acid, the logarithmic value (pKa) of the reciprocal of the acid dissociation constant at 25 ° C is preferably 1. 1 ~ ~ 7.0 of organic acids, such organic acids, such as aspartic acid, alanine, glycine Amino acids; acid acids such as formic acid, citric acid, acetic acid, oxalic acid, tartaric acid, lactic acid, phthalic acid, propionic acid, maleic acid, butyric acid, and frequency acid. Among them, oxalic acid (pKal = 1. 〇4, pKa2=3.82), maleic acid (pKai=1.84, pKa2=5.83), tartaric acid (pKal = 2.87, pKa2 = 3.97), malic acid (pKa = 3. 23, pKa = 4.77), acid (pKal = 2. 90' pKa2 = 4. 35' PKa3 = 5. 69), lactic acid (pKal = 3. 64) is better. Since the molecular weight of oxalic acid is small, the amount of acid equivalent by weight is large and optimum. The necessary condition for the substrate for injecting the ground plate of the present invention is that the colloidal silica stone and the monic acid are used as the main material, and the above-mentioned inorganic acid and organic acid are contained as a gelling agent, and 2 to 7. More preferably, the substrate material for in-situ injection of the present invention comprises a combined buffer solution of an organic acid having a logarithmic value (pKa) of no reciprocal of the acid dissociation constant at a force of 25 C, and Between: has a good effect. As far as the inventors have discovered, the gelation time has a great dependence on the injection & pH. By injecting the ground disk into the liquid material of the substrate material, the pH buffer cold liquid can make a slight difference in the material to the pH. The variation of 201200581 is small, and even if the concentration of the injection material is small due to the groundwater, the fluctuation of the pH is small, so that the variation of the gelation time becomes small, and the predetermined gelation time can be easily substantially realized. The colloidal two-gas fossil of the main disk of the I disk material for the surface of the present invention is not particularly limited, and the commercially available product n, the second main material, is also not particularly limited, and the city can be used. For the products sold, it is better to use No. 3 soda ash soda or No. 4 citrate soda. No. 3 citrate soda is produced in large quantities, so it is cheap and good. The colloidal silica dioxide used in the present invention is produced by using ascorbic acid soda as a raw material. The soda citrate is preliminarily diluted to a concentration of cerium oxide of 3 to 7% by weight, and is contacted with a strongly acidic cation exchange resin to remove an aqueous solution of active oxalic acid. The active aqueous acid solution is about 2 to 4, and the alkaline agent is added to the active aqueous acid solution to pH 9~1G·5, and the heating is 6 (M〇(TC makes the particles grow (mature)' or the heating is 6{M00t). The alkaline agent is added with an active aqueous solution of citric acid to a pH of 9 to 10.5' to maintain 6 〇 to 1 〇〇. (The temperature of the particles is allowed to grow (mature). After the particle size is 5 to 2 〇 nm, the cerium oxide is concentrated by reverse osmosis. The concentration is ίο% by weight or more. The particle diameter of the present invention is preferably 5 to 2 Å. The colloidal cerium oxide contains at least 9% by weight of cerium oxide particles. Further, the concentration of cerium oxide is In the range of 1 〇 to 3 〇% by weight, in order to simplify transportation and reduce transportation cost, it is preferable to use a product having a high cerium oxide concentration. The substrate material for the site for injecting of the present invention may further be combined with other additives, for example, For blending gelation time adjuster, for example, if the gelation time is shortened, slaked lime, gasification mother, gasification town, gas oxygen 201200581 magnesium, etc., or cement (portal cement, bauxite) can be used. Cement, blast furnace cement) In the initial or initial gel strength. The substrate material for the site for injecting in the present invention is a liquid A which is prepared by mixing colloidal silica, inorganic acid, organic acid and water, and diluting the liquid B of soda citrate with water.

The formulation of liquid B is shown in Table 12. The liquid A was based on the formulation described in Table 13 and the amount of the organic acid was changed by adding the amount of water to the final addition of 300 ml. The gelation time of the pH of the mixed solution (injection material) was measured. The material formulation of the liquid A is shown in Table 1 - 4b. A compound in which phosphoric acid is further added to the liquid A other than the organic acid is also carried out. The pH and gelation time of the AB mixed solution (injected material) were measured, and the results are shown in Fig. 5 and Fig. 6. In the region of pH 3 to 4 in the figure, the sample to which the organic acid was added changed linearly as compared with the change in the pH of the added phosphoric acid. Among them, the slope is slightly dithered due to the small pKa due to oxalic acid (pKal = l. 〇4, pKa2 = 3.82). Table 12. Soda Citrate (g) 79.20 B Water (g) 40 Subtotal (g) 119.20 (ml) 100 Table 13.
