The means 20 may also have a stronger bonding force since the main body 30 is connected to each other.

Hereinafter, with reference to Figure 7 will be described in detail with respect to the bank eye block unit according to a first embodiment of the present invention. Referring to FIG. 7, in the shore block unit of the present invention, vegetation holes 11 are formed in the center of the plant so that plants can grow, and through holes 13 penetrating from one side of the edge to the other side are formed and mutually formed. The main body 10 disposed adjacent to each other, and formed in a shape corresponding to the shape of the main body 10, and an interior space is formed so that a plurality of the main body 10 can be disposed adjacent to each other and disposed in the layout space The support part 100 formed to surround the outer side of the plurality of main bodies 10, and the support part 100 at one end to constrain the main body 10 disposed on the support part 100 to the support part 100. Fixed to one side of the other end is passed through the through hole 13 of the main body 10 and the connecting means 20 fixed to the other side of the support portion 100, the fixing to couple the mutual support A clamp is provided.

It may have a structure of the main body according to the second and third embodiments of the present invention described with reference to 6. In addition, since the main body 10 and the connecting means 20 are the same as those described in the bank block according to the first embodiment of the present invention, duplicate descriptions are omitted and the same reference numerals are used.

The support part 100 is an empty rectangular or square frame, which is disposed adjacent to each other, and is made of an ocher composition including ocher. The ocher composition forming the support part 100 will be described later. A plurality of main bodies 10 are arranged in contact with each other in an arrangement space in the support part 100, and reproductive spaces are formed in a portion where the main bodies 10 abut so as to grow plants by the inlet grooves 12.

In the above-described protection block main body according to the present invention is applied to the shape shown in Figures 1 to 8, that is, the upper surface of the main body is formed flat, as shown in Figure 9 in more detail the outer peripheral surface of the main body 50 The surface may be roughly formed in the form of natural stone. As described above, the revetment block body 50 having a natural stone form may be in harmony with the surrounding environment, and may be filled with soil or sand on the upper part of the revetment block body 50 to allow plants to grow.

Hereinafter, the ocher composition constituting the main body 10, 30, 40 and the support parts 100, 200 of the present invention will be described in detail.

The ocher composition for molding the main body 10, 30, 40 is 5 to 30% by weight of calcined ocher or unfired raw ocher powder, 3 to 10% by weight of slaked lime, blast furnace slag with a powder degree of 6000 to 8000 cm2 / g. 20 wt%, 30 to 65 wt% of crushed gravel and crushed sand, 0.2 to 1.0 wt% of any natural water reducing agent selected from the group consisting of naphthalene-based and lignin-based and polycarboxylic acid-based, urethane acrylate resin and polymethylmethacrylate And 0.1 to 10% by weight of any one binder resin selected from the group consisting of hydroxyethyl methacrylate and a balance of water. Water is included in the balance. Therefore, the addition amount of water is included 5 to 15% by weight depending on the content of the other materials.

Ocher contains calcium carbonate (CaCO ₃ ), silica (SiO ₂ ), alumina (Al ₂ O ₃ ), iron, magnesium (Mg), sodium (Na), kali (K ₂ O), etc., mainly 0.05 ~ 0.01mm As a yellow mineral composed of silt particles, it emits a large amount of far-infrared rays and thus has a beneficial effect on the human body such as promoting blood circulation and metabolism and neutralizes cement toxicity.

The loess applied to the present invention may be calcined calcined ocher or non-baked raw ocher. Unfired raw ocher is used in the form of powder ground in a crusher after drying the ocher collected from the soil. The calcined ocher is put into the calciner, and the calcined ocher is calcined at a temperature of 500 to 800 ° C. for about 20 minutes, and then ground into a mill to use a powder form filtered using an automatic screen sieve. The loess which has undergone such plastic processing is more curable than the raw loess. On the other hand, if the firing temperature is less than 500 ℃ can obtain a low-hardness ocher powder, and if the firing temperature exceeds 800 ℃, since the sufficient degree of curing is obtained, unnecessary energy may be consumed to secure the degree of curing.

The content of ocher powder may be 5 to 30% by weight in the total ocher composition. When the content of the ocher powder is less than 5% by weight, the eco-friendly effect obtained by the inclusion of the ocher powder may be insignificant. On the other hand, if the content of the ocher powder exceeds 30% by weight may not increase the expected effect by increasing the content any more, it can be seen that there is no economic feasibility to meet the expected effects such as strength. In addition, the amount to which other compositions are added may be reduced, so that the strength of the ocher composition to be formed later may be lowered.

Slaked lime is included to neutralize the acidity of the ocher composition. Slaked lime may contain mainly calcium oxide (CaO), which serves to supply alkali to the ocher composition.

The content of slaked lime may be 3 to 10% by weight. If the content of slaked lime is less than 3% by weight, the effect of supplying alkali to the ocher composition is insignificant, and if it exceeds 10% by weight, the ocher composition may be generally alkaline.

Blast furnace slag is included to solidify the ocher composition through neutralization and hydration by chemical ion substitution of metal ions when mixed with water. At this time, slag may be used as the blast furnace having a powder degree of 6000 to 8000 cm < 2 > / g. If the blast furnace slag powder is less than 6000 cm 2 / g, the compressive strength of the block to be formed into the ocher composition may be weakened, so that it may be easily broken or cracked. And when the powder degree exceeds 8000 cm 2 / g, since the compressive strength of the block product is no longer increased, there is an undesirable aspect in terms of economics of the process.

The content of blast furnace slag is preferably 5 to 20% by weight. If the content of the blast furnace slag is less than 5% by weight, the effect of solidifying the ocher composition may not be sufficiently exhibited. As a result, a block product having a low compressive strength can be formed. If the blast furnace slag content exceeds 20% by weight, the solidification may be excessively excessive and the overall physical properties of the ocher composition may be weakened.

The type of aggregate contained in the ocher composition is not particularly limited. A mixture of crushed gravel and crushed sand can be used as the aggregate. Crushed gravel is suitable for the quality of crushed coarse aggregate for concrete with a maximum particle diameter of 13mm or less, and crushed sand is suitable for the quality of crushed sand for concrete with a maximum particle diameter of 5mm or less. In addition, to improve the performance of the ocher composition by replacing some of the aggregates with environmentally friendly aggregates such as silica sand, ganban stone, jade can be used to increase the environmental friendliness.

The content of aggregate consisting of crushed gravel and crushed sand may be 30 to 65% by weight. The mixture of crushed gravel and crushed sand may be 1 to 2: 1 by weight. If the content of the aggregate is less than 30% by weight, the skeleton of the block product may not be properly formed, and the input of other materials may be increased and the economic efficiency may be lowered. When the content of the aggregate exceeds 65% by weight, the strength of the composition may be lowered or difficulty such as surface finishing may occur. For this reason, the content of the aggregate can be produced in the ocher composition with improved strength and construction properties by adjusting the appropriate content within the range of about 30 to 65% by weight based on the entire ocher composition.

Natural water reducing agents may be included to aid in the solidification of the ocher composition. The natural water reducing agent may be at least one selected from the group consisting of, for example, naphthalene-based, lignin-based and polycarboxylic acid-based.

The content of natural water reducing agent in the whole of the ocher composition may be 0.2 to 1.0% by weight. If the content of the natural water-reducing agent is less than 0.2% by weight, the water-reducing effect is lowered. If the content of the water-reducing agent is more than 1.0% by weight, the water-reducing effect is excessively increased, which may cause problems in construction. .

A binder resin is used to enhance the durability of the ocher composition. In addition, the binder resin may improve the bonding strength between the other compositions included in the ocher composition, salt resistance, copper resistance, sulfuric acid resistance, and the like.

The binder resin can be at least one selected from the group consisting of, for example, urethane acrylate resins, polymethyl methacrylates and hydroxyethyl methacrylates. Here, the urethane acrylate resin is a hybride resin having both urethane and acrylate characteristics. Such urethane acrylate resins can generally be prepared by polymerization of a urethane prepolymer with a hydroxyalkyl acrylate. The urethane prepolymer is formed by a polymerization reaction of a polyol and isocyanate, and the types thereof are various.

The content of the binder resin may be 0.1 to 10% by weight in the whole ocher composition. When the content of the binder resin is less than 0.1% by weight, the effect of strengthening the binding force between the other compositions in the ocher composition is insignificant. When the content of the eco-friendly binder resin exceeds 10% by weight, the bonding strength between the different compositions in the ocher composition is strengthened, but the workability is reduced, so that an additional process may be required in the manufacture of the ocher composition, so that the overall economical efficiency of the process May not be desirable.

On the other hand, the ocher composition according to the present invention may include water, the mixing ratio (water: binder resin) of the water and the binder resin may be 2: 1 to 5: 1. In consideration of the overall bonding strength and processability between the compositions contained in the ocher composition, it is preferable to mix water and binder resin in advance within the above ranges and then mix with other compositions.

And in order to reinforce the strength and crack resistance of the main body and the support formed by the ocher composition may further comprise a reinforcement.

As the reinforcing material, it is preferable to use a reinforcing material formed of geotextiles and environmentally friendly resins, for example, cellulose. However, a reinforcing material commonly used in the market may be arbitrarily selected and used within the range of not impairing the present invention. . At this time, the reinforcing material may not only improve the firmness of the bonding force, but also reduce the crack of the block and impart an elastic force to the block.

The content of the reinforcing material may be 0.2 to 1% by weight in the whole ocher composition. If the content of the reinforcing material is less than 0.2% by weight, the effect of the reinforcing material may be insignificant. When the content of the reinforcing material exceeds 1% by weight, it may be excessively added in relation to other compositions to lower the physical properties of the entire composition.

In addition to the above-mentioned ocher composition, it is a matter of course that the main body can be molded using a conventional soil composition.

Hereinafter, the manufacturing method of the main body which concerns on this invention is demonstrated easily.

First, 5 to 30% by weight of calcined ocher or unfired raw ocher powder, 3 to 10% by weight of hydrated lime, 5 to 20% by weight of blast furnace slag of 6000 to 8000 cm2 / g powder, crushed gravel and crushed sand 30 To 65% by weight, any one natural reducing agent selected from the group consisting of naphthalene-based and lignin-based and polycarboxylic acid-based, 0.2-1.0% by weight, a group consisting of urethane acrylate resin, polymethyl methacrylate and hydroxyethyl methacrylate The ocher composition is formed by kneading by mixing 0.1 to 10% by weight of any one of the binder resins selected from the balance, and remaining water.

And the ocher composition is carried out in a molding step for molding. Molding may be press-molded by putting the dough into the mold of the vibration pressure molding machine. Moreover, it can shape | mold by putting into the shaping | molding die of a hydraulic press. After molding, it is dried to prepare a rake block and a rake block unit having the same. Drying can be performed by a conventional method. For example, it may be naturally dried for about 5 to 30 days, or naturally dried after steam curing for 4 to 6 hours.
