The present invention relates to an ocher lake block, and in particular, when forming an ocher mixture containing an alkaline adjuvant, an acid additive, water and a natural resin into an ocher lake mold, a wire mesh for preventing soil leakage on the bottom surface. It is possible to improve the strength and durability of ocher lake blocks by facilitating the planting of ocher lake blocks by putting ocher mixtures of the above-mentioned mucus state and preparing the ocher lake blocks with integrally attached wire meshes. In addition, the present invention relates to an ocher lake block and a method of manufacturing the same to prevent the outflow of soil.

In general, ocher has been widely used as a building material for building walls, floors, and fireplaces in kitchens. In addition, it has been used as an arable land for redevelopment, earthenware, and tile ceramics, as well as for arranging rice fields for improving characteristics, fish farm floors, and cowshed floor coverings.

In addition, the efficacy of loess includes the effect of far-infrared emission. Ocher is absorbed by the human body by radiating beneficial far-infrared rays, so the metabolism is smooth and blood circulation is active, thus preventing the aging of the human body, promoting metabolism, and eliminating chronic fatigue. In particular, ginseng and ginkgo biloba grown in loess is very good quality, fermentation of kimchi, soybean paste, soy sauce, etc. under the surface of the loess, the fermentation is active, the quality is improved.

Despite these many advantages, there is no suitable technology that can be utilized as a building material by commercially mass-producing ocher. Therefore, most of the bricks manufactured using building materials are currently made of concrete as the main raw material, but concrete is excellent in terms of bonding strength, but has a disadvantage in that heat loss is large because it is harmful to the human body and has low thermal insulation effect. .

Therefore, in recent years, attempts have been made to manufacture bricks, sidewalk blocks, and raft blocks as loess in order to apply the loess to various building materials due to the architectural climate that emphasizes well-being.

On the other hand, the above-mentioned protection block is used by closely connecting a wide thick square plate-like concrete plate in order to prevent the loss of soil in the water flow part after the stones or soil stacked on both sides of the river or river banks It is a kind of block.

However, the above-mentioned shelter block should have high strength and hardness because flooding occurs due to heavy rains on the embankment, so that when a large amount of water flows into a river or a river, the sediment should be prevented from leaking and withstand a large flood. Therefore, the existing attempts to fabricate lake blocks using loess have not been very successful.

In addition, in the conventional concrete revetment block, the non-woven fabric is laid on the earth and sand, and the plant is planted in the planting hole formed in the revetment block so that the plant penetrates the non-woven fabric and roots in the soil. Because of the tendency to not penetrate the nonwoven fabric properly, the planting ends in failure, and the vegetation fails to grow, causing a vicious cycle of collapse of the dike due to flooding.

In addition, the conventional concrete protection block is made of concrete, so when the protection block is discarded due to its durability, or if it is lost by a flood, it is discarded in nature and the toxicity of the concrete is exposed to the material, which adversely affects the natural environment. There is a problem that is not environmentally friendly such as Mitch.

The present invention has been made in view of this point, and when forming an ocher mixture mixed with an alkaline adjuvant and an acid additive, water and natural resin in the ocher to mold ocher lake block, a wire mesh for preventing soil leakage on the bottom surface It is possible to improve the strength and durability of ocher lake blocks by facilitating the planting of ocher lake blocks by putting ocher mixtures of the above-mentioned mucus state and preparing the ocher lake blocks with integrally attached wire meshes. The purpose is to prevent the outflow of sediment.

1 is a flow chart illustrating a manufacturing method of ocher lake block according to an embodiment of the present invention.

The method of manufacturing the ocher lakes in accordance with an embodiment of the present invention has an ocher drying step (S10) for drying so that the moisture content of ocher within 10 to 15%.

Drying the ocher is to allow the ocher to be mixed with the other mixture in the correct composition ratio.

If the moisture content of the loess is more than 15%, the loess becomes cold and it is difficult to mix with other materials.

When the moisture content of the loess is 10% or less, the loess is blown to generate dust.

Therefore, the moisture content of the loess is preferably dried to 10 to 15%.

The ocher is uniformly pulverized into particles of 0.5 to 4 mm to be easily mixed with other materials, and more preferably, the ocher is pulverized into particles of 0.5 to 1 mm.

As the ocher is uniformly pulverized as described above, the crushed ocher is more uniformly mixed with other materials.

When the particles of ocher are 0.5 mm or less, the particles are too small to increase dust, and when the particles of ocher are 4 mm or more, the particles are large, so that mixing with other mixtures is more than when the particles are 0.5 mm to 4 mm. It doesn't work out well.

On the other hand, in the ocher milling step (S20) of the present invention, the ocher is based on 100 parts by weight of ocher, 25 to 35 parts by weight of ocher ground into particles of 0.5mm to 1mm, ocher 45 ground into particles of 1mm to 2.5mm It may be composed of ocher having a composition ratio of 15 to 25 parts by weight, crushed into particles of ˜55 parts by weight, 2.5 mm to 4 mm.

Various changes will be possible within the concept of dense technology, such as mixing different proportions or using alternative materials.

In addition, the acid additive comprises at least one of sulfonic acid or citric acid, and in addition to this, a material having an acid component may be used as an acid additive according to an embodiment of the present invention.

Salt and water are generated as the acidic additive is added and reacted with the alkaline adjuvant.

The alkaline adjuvant and the acidic additive are uniformly mixed with the loess, and as a result, water is generated by the neutralization reaction of the alkaline adjuvant and the acidic additive. Are combined with each other. As a result, the bond is more firmly combined with the molecules of the loess, thereby increasing the viscosity and further improving durability.

On the other hand, the water generated during the neutralization reaction, because it is uniformly spread in the interior of the loess serves an additional role to increase the stiffness by rubbing the tissue. That is, the water generated during the neutralization reaction is supplied to the part of the ocher mixture that is not supplied sufficiently to the inside of the ocher, the alkaline reinforcing agent and the acid additive, so that the tissue becomes more dense.

In addition, limestone and gypsum constituting the alkaline reinforcing agent may be used as a cement material, and the alkaline reinforcing agent may be mixed with the loess to further increase the stiffness of the ocher lake block.

On the other hand, in obtaining the above-mentioned ocher mixture, the stiffness and durability of the ocher lake block is significantly lowered when the alkaline adjuvant and the acid additive are not used. Thus, the ocher lake block according to the embodiment of the present invention is the use of the alkaline adjuvant and the acid additive. Most preferred.
