In general, the operation rate of a port depends on the waves entering the harbor from the sea and the wave waves entering the harbor beyond the breakwater and the reflected waves generated from the walls of the harbor. The waves entering the harbor from the open sea can basically be reduced by properly placing breakwaters, and the waves exceeding the tiandan height of the breakwater can be reduced by increasing the tiandan height.

The breakwater is a marine structure designed to shelter the blue waves of the open sea, prevent oversea waves to the inland sea, maintain the calmness of the inland sea, promote the safety of ships anchored, and protect the waters and harbor facilities in the harbor from blue waves. Depending on the nature or size of the ground or wave, there are several types of breakwater structures, such as sloped or upright.

In particular, in order to install a breakwater that is built on a slope, a sofa block having a structure that is easy to construct and conveniently protects the facilities adjacent to the coast by effectively couching the waves that invade the sea is needed, and also has high hydrophilicity that anyone can easily contact the sea. There was a need to develop a breakwater structure with a beautiful landscape.

Therefore, it is necessary to effectively protect the facilities adjacent to the coast by effectively couching the waves that invade the open sea, and to secure the stability of ships sailing the offshore, and to develop a sofa block having a high hydrophilicity, a robust and easy-to-install structure. It is a required situation.

In addition, the shoreline has been constructed to prevent coastal erosion due to the blue sea, but the conventional masonry shores or shores formed by structuring concrete blocks do not effectively couch the waves that invade the sea. Due to the formation, the sediments formed on the shoreline, that is, sand, etc. are lost, and the tetrapod sofa block is cylindrical in shape, so that there is little vortex generation during the flow of algae, and the viability of aquatic organisms has been depleted and the coast has been criticized. In addition, in the case of the existing tetrapods, the center is thicker and the size of the cylinder becomes smaller as it goes to the horn of the outer part. In addition to numerous occurrences, the installation of concrete lumps for the purpose of the sofa effect on the coast, which is a treasure trove of marine ecosystems, destroys the spawning grounds of habitats and habitats for habitats, resulting in a reduction in fishery income through the reduction of fisheries resources. Contradictions arose from the construction of the shores.

Therefore, it is possible to effectively prevent the waves from invading the sea to prevent soil collapse and loss, to effectively protect the facilities adjacent to the coast, to ensure the stability of ships sailing offshore, and to protect the sands of existing coasts. There is an urgent need for the development of a safeguard structure.

The reverse casting is suitable for the manufacture of 1-25 ton of sofa block, which is relatively light in weight. When producing 1 to 25 tons of sofa blocks, the use of a general pour method is also relatively small amount of raw materials used, so the spreadability of the raw materials in the formwork may not be good. However, when the reverse casting is used, the raw material can be directly poured on the formwork for forming each leg 201 of the sofa block, so that the strength of the sofa block as a whole is not only constant but also the strength can be improved. In addition, the generation of air bubbles in the sofa block generated by air in the manufacturing process of the general sofa block can be significantly reduced. After the manufacture of the sofa block using the inverse casting, dismantle part of the formwork and the support (FIG. 6 (g) and (h)), and the form of the inverted triangular pyramid pyramidal pyramid form again (Fig. 6 ( i), (j), (k) and (l)), all of the formwork is dismantled (m) of Figure 6 to obtain a sofa block.

Here, the triangular pyramid is a shape in which three legs 201 of the four legs 201 of the sofa block are in contact with the floor and the other leg 201 faces the opposite direction of the floor. In order to manufacture the formwork is assembled and poured in the same form. The spiking is a suitable method when manufacturing a sofa block of 30 to 100 tons relatively heavy. After the manufacture of the sofa block is dismantled the formwork (Fig. 7 (j)).

In the present invention, a method of forming the concave-convex 300 on the surface of the pour mixture to provide the habitat and hiding place of the fry, the shape of the concave-convex 300, for example, trapezoidal mold (mold) It can be formed using, but if it is a method that can form the concave-convex 300 in the sofa block made of a mixture of ready-mixed concrete, it is not limited thereto.

In the present invention, the curing may be characterized in that the wet curing for 26 to 27 days. When the curing period is 26 to 27 days, the physical properties of the sofa block finally produced are excellent.

When curing, protect the sofa block shaped molding from sunlight, cover the curing cloth to prevent cracking due to rapid drying, and do not apply the impact to the molding under curing from the outside.

In another aspect, the present invention relates to a method for constructing a sofa block characterized in that the sofa block is tied with a rope connected to a crane, and then constructed by a lamination method or a difficult method so that the porosity is 45 to 65% (FIG. 8).

When the porosity is 45 ~ 65% can exhibit the optimal sofa effect.

In the present invention, the layering method may be characterized in that the leg 201 of the adjacent sofa block alternately staggered construction. When the legs 201 of adjacent sofa blocks are alternately staggered, the sofa block is firmly constructed by the engagement phenomenon and the sofa effect is excellent. Moreover, it can also be constructed in a single layer, and can also be piled up in two layers. For example, in the area where the waves are relatively large, two or more floors are installed by the lamination method to increase the porosity to 56%, thereby reducing the number of blocks mounted and maximizing the effects of reflectance and crest transfer rate (FIG. 9).

In the present invention, the dripping method may be characterized in that the construction is in contact with the leg body 201 of the adjacent sofa block. By the polyhedral legs 201 in the sofa block abut each other, not only the sofa effect, but also the spawning and habitation place of the aquatic organisms can be provided in the space generated between the adjacent sofa blocks. For example, when constructing a sofa block in a single area in a relatively small wave area, construct it with a trickle construction method to increase the porosity to 56%, reducing the amount of block placement and maximizing the effects of reflectance and crest transfer rate. (Figure 10)

In the present invention, the structure of the rope is in contact with the sofa block is made of a fiber material and the inside is made of steel wire, the structure of the portion of the rope is not in contact with the sofa block is made of a wire with strong tensile force It may be characterized by.

When using the rope, there is an advantage that can be transferred and construction without damaging the surface of the echo block. In addition, the construction of the rope can be performed more efficiently by changing the rope knotting method according to the weight of the fish block.

When the sofa block according to the present invention is installed on the shore, it is possible to effectively enhance existing functions of minimizing reflected waves and reducing the occurrence of moon waves while efficiently couching the waves flowing from the open sea. Can provide.

In addition, the three legs 201 integrally formed on the body portion 100 of the sofa block has a polyhedron shape, so that the vertex portion of each side contacting each other forms a protruding portion, thereby generating a vortex while increasing the sofa effect. Improve the viability of marine life.

In addition, each of the three circular surfaces included in the body portion 100 of the sofa block has a concave-convex 300 is formed can perform a function to provide a hiding place so that the cheerleader does not become a prey of large appetite animals.

In addition, according to the weight of the sofa block to be manufactured can be manufactured using low-cost and high-efficiency eco-friendly sofa block by improving the workability and strengthening the durability of the concrete by using a reverse pouring or static casting method.

In addition, by using the dripping method or the layered method according to the strength of the wave during the construction of the sofa block, it can effectively respond to the strength of the wave, it is possible to maximize the reflectance and crest transfer rate.

In particular, in the case of using the lamination method, the sofa blocks are connected together as one structure by the interlocking effect of the leg 201 of the sofa block, so that even if strong waves are driven, the waves can be couched and each other is not damaged by colliding with each other. .

After all, when using the sofa block, the manufacturing method and the construction method according to the present invention, it is possible to provide a scattering habitat refuge of aquatic organisms, increase the sofa effect, improve workability to improve quality and reduce manufacturing costs Can improve economics.
