Description

Soil floor packing method

The present invention relates to a soil floor pavement method, and more particularly, to a soil floor pavement method that has been applied to the upper surface of the light concrete layer at the time of the floor paving, such as footpaths, bicycle roads, driveways and ondol floors.

Soil is the most primitive road material. Even if the soil is not used as a road material, the soil becomes a natural road material because it is easy to make roads with non-rock soils as roads. However, since these roads have weak durability and strength, concrete or asphalt, which have strength and durability, are the main axis of the road.

In addition, ocher has been widely used since ancient times as an important building material, but is rarely used due to problems of productivity and durability, and the product has been pouring into the flooring in consideration of the health effects on the human body.

Conventionally, pavement using ocher was laid by mixing soil cement (lime or chemical material) such as Nubeton and Fujibeton with soil. Since the entire thickness of the road was laid only in the soil layer, the construction cost was enormous. Due to the weak strength, there was a problem of loss or durability, and during the rainfall, the soil road was soluble in water and thus could not be used as a road paving material.

However, despite the fact that soil flooring has problems in terms of durability and strength, soil provides 1) a natural environment, 2) various natural colors such as loess, red soil, masato, kaolin, black clay, and silica sand, and 3) soil. The floor can be different from the cement, and 4) the soil has the advantage of emitting far-infrared rays, which is beneficial to the human body.

It is therefore an object of the present invention to provide a soil floor pavement method having durability and strength as a road suitable for various uses utilizing the advantages of the soil.

It is also an object of the present invention to provide a soil floor paving method that is cheaper construction cost by installing a soil layer on the upper end of the light weight concrete layer during floor paving.

In the case of the soil passing through 50% or less in the # 200 sieve is used, and when the thickness of the packaging is more than 10㎜, it is preferable to use the soil passing within 30% in the # 200 sieve.

And when the soil layer requires water permeability, it would be preferable to use 90-100% of the passage in 4mm sieve, 40% of the passage in 1mm sieve and less than 10% in the # 200 sieve.

The binder mixed in the soil may be a solution or emulsion of acrylic, urethane, epoxy or unsaturated resins, and when the concrete surface is dried in a dry state, the emulsion-type resin may be 0.05 parts by weight based on 100% of the solid content. It will be preferred to use 1.0 parts by weight. And when the binder is mixed with the soil surface is wet or dry, it is preferable that the emulsion type acrylic resin is used 0.05 to 1.0 parts by weight in 1 part by weight based on 100% of the resin content.

If necessary, 0.3 parts by weight of stone powder or cement is used, and dilute material such as thinner is used as a diluent to increase the dough hanging within 50% of the resin used, and water is used when using emulsion type resin. It can be used within 50% of the mixture.

If necessary, 0.03-0.07 parts by weight of pigment is used in 1 part by weight based on 100% of solid content to replenish the soil color, and crushed tires having a particle size of 4 mm or less are used within 30% of the soil use for elastic packing. It can be used and crushed waste glass with particle size less than 4mm can be used within 30% of soil usage for light reflection of soil layer.

If necessary, the surface is laid in a concave-convex shape by unfolding the surface layer with the surface scraper of FIG. 2 after packing the ocher layer. And if necessary, the hairdressing shoe of FIG. 3 and the surface of the ocher layer is brightened with a trowel, and plastered with oil, thinner, etc. so that the ocher does not get on the trowel, or the trowel is burned and used. . And in order to make the finish more efficient, the soil layer may be laid, covered with vinyl, compacted with a compact roller, and then cured. In this way, the soil layer can be constructed quickly.
