1 is a flowchart of a method for constructing a soil package using the soil packaging composition of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a flow chart of the soil packaging method using the soil packaging composition of the present invention.

As shown in the drawings, the soil packaging method using the soil composition of the present invention construction preparation step (S10), aggregate layer compaction step (S20), earth packaging composition installation or spraying step (S30), earth spray composition further spraying It comprises a step (S40), earth packing compaction step (S50), finishing step (S60).

The construction preparation step (S10) is a step of digging the ground of the site to be carried out the soil packaging and compacting the ground.

At this time, when the base plate is compacted, it is desirable that the surface of the base is well selected and the foreign matters are removed so that water does not accumulate, and then compactly compacted with an electric roller so that the roadbed finishing surface of 95% or more of compaction density does not deviate more than ± 3 cm from the planned height.

The aggregate layer compacting step (S20) is a step of laying aggregate on the compacted base, and compacting the aggregate layer.

At this time, it is preferable that the compacted aggregate layer is such that damage to the traffic during the construction vehicle and dropping of the aggregate are not generated.

The soil packaging composition laying or spraying step (S30) is mixed by laying the ground clay and soil packaging composition in a ratio of 10: 1 in the compacted aggregate layer or laid ground clay in the compacted aggregate layer, and then spraying the soil packaging composition It's a step.

That is, if the raw alumina of the site is a good masato or viscous soil, after laying the raw alumina on the compacted aggregate layer, the soil pavement composition is sprayed,

If the raw alumina of the site is not high quality masato or fine soil, the raw alumina and the soil pavement composition are mixed and laid in a ratio of 10: 1 to the compacted aggregate layer.

At this time, the soil packaging composition comprises 20 to 30% by weight of the soil hardener with respect to 100% by weight of water, the soil hardener is 35 to 64.3% by weight of acrylic resin, 20 to 30% by weight of lithium silica, polysiloxane 10 20 wt%, polyvinyl acetate 3-7 wt%, starch phosphate 1-3 wt%, fatty acid 1-3 wt%, silicon resin 0.5-1 wt%, polysorbate 0.1-0.5 wt% It is preferable that the composition is mixed with 0.1 to 0.5% by weight of hydrogen peroxide.

The acrylic resin has a penetrating power and a deterioration inhibitor function, and any one compound selected from methyl acrylate, ethyl acrylate, isobutyl acrylate, methyl methacrylate, ethyl methacrylate and acrylonitrile Use,

At this time, when the acrylic resin is less than 35% by weight with respect to 100% by weight of the soil hardener, the penetration is weak, when more than 64.3% by weight, the penetration is strong, but the adhesion is weak, there is a difficulty in the construction of the soil.

The lithium silicate [Lithium Silicate] is a silicate-based liquid product of a higher molar ratio (molar ratio) than sodium silicate or potassium silicate. In the case of sodium silicate, a solution of 4 to 4.5 moles having a SiO 2 concentration of 10% or more has a very high viscosity. In the unstable state, lithium silicate is stable at room temperature and has a low viscosity even when the SiO2 concentration is 20% and the molar ratio is close to 8.

The lithium silicate penetrates between the soils, hardens the protective coating role and soils, and is effective for surface hardening.

In this case, when the lithium silicate is less than 20% by weight, the permeability is difficult to exhibit the surface strengthening properties, and when it exceeds 30% by weight, there is a problem that cracks occur during soil packaging.

The polysiloxane is a compound in which a silicon atom and an oxygen atom alternately combine to form a chain structure. The polysiloxane has a durability that reaches a glass level, is resistant to heat or wind, is excellent in transparency, and has water repellency.

At this time, when the polysiloxane is less than 10% by weight, transparency and water repellency are inferior, and when it exceeds 20% by weight, transparency and water repellency are too large.

The polyvinyl acetate is used as an emulsion of polyvinyl acetate as a material of a synthetic pool. Polyvinyl acetate is insoluble in water, so use it with other emulsifiers.

This, polyvinyl acetate helps to adhere well to the surface of the soil, evaporates at a low temperature to attract moisture and serves to promote the chemical reaction of the alkoxysilane.

At this time, when the polyvinyl acetate is less than 3% by weight, the adhesiveness is inferior, and when it is more than 7% by weight, the adhesiveness is too large.

The starch phosphate is used as a freeze stabilizer, thickener, and emulsifier, and is used in starch phosphate, starch phosphate, monoostarch phosphate, phosphated distarch phosphate, and acetyl phosphate starch. (acetylate distarch phosphate) using any one compound selected.

At this time, the starch phosphate is less than 1% by weight freeze stability, emulsification is poor, when more than 3% by weight freeze stability, emulsification problem is too large.

The fatty acid is a carboxylic acid of a hydrocarbon chain having one carboxy group (-COOH), and refers to a monovalent carboxylic acid in a chain form and is used as a melting point.

These fatty acids are not very soluble in water, but in alkaline solutions, the carboxyl groups of the fatty acids are ionized and have a strong polarity, thereby making them water soluble.

In this case, when the fatty acid is less than 1% by weight, the melting point becomes high, and when the amount is more than 3% by weight, there is a problem of freezing stability and low melting point.

The silicon resin [silicon resin] is used as an antifoaming agent and when there is less than 0.1% by weight there is no foaming, when more than 0.5% by weight there is a problem that too much foaming.

The polysorbate and hydrogen peroxide are used as emulsifiers and dispersants. When the amount is less than 0.1 wt%, the efficacy of the emulsifier and the dispersant is lowered. There is.

Soil pavement composition consisting of the mixture is characterized in that Ettringite is generated within 24 hours to accelerate the hydration reaction to the early strength development, the expression strength is also high to prevent the occurrence of cracks to minimize the installation of the joint.

The soil packaging composition additional spraying step (S40) is a step of further spraying by mixing the soil packaging composition and water in a ratio of 1: 5 to 10 after spraying the soil packaging, 1-2 hours.

The soil packaging composition additional spraying step (S40) is a soil mixing composition to increase the penetration rate between the soil soil due to the inclusion of additional flesh by mixing the ratio of water higher than the soil packaging composition laying or spraying step (S30).

The soil pavement compacting step (S50) is a step of pruning the soil pavement finishing surface after 2 to 6 hours, after further spraying the soil packaging composition.

After the soil packaging further spraying, it is preferable to set the winter season to 2 hours and the winter season to 6 hours.

At this time, when the finishing surface is higher than the planned height, it is preferable to cut the finishing surface through a concrete cutter with a water-cooled diamond saw blade or a wearable saw blade to compact.

The finishing step (S60) is a step to dry curing by protecting from the impact on the surface after the compaction of the soil, the pressure or scratches from the external impact.

At this time, the curing is after the additional spraying step of the soil packaging composition (S40), 72 hours to 96 hours is preferably natural drying curing at an average temperature of 21 ℃ or more, conditions of the surrounding environment and conditions of the air temperature conditions of the soil packaging composition The curing time is increased by 12 hours depending on the particle size.

In addition, before curing, the walking or movement of the vehicle is limited at all and it is preferable to protect it from external influences such as artificial drying, temperature change, load, impact, rainy weather.
