- wave dissipating blocks are used to prevent the soil loss and are installed on a part of a breakwater or a shoreline which receives large waves to disperse or dissipate wave energy and to reduce reflected waves, and mainly refer to concrete blocks.
- a tetrapod having the shape of four horns has been used the most, and a dolos and a sealock made by modifying the tetrapod are also frequently used recently.
- the tetrapod is installed on the slope of a breakwater to form a single layer or double layers, or during the construction of a submerged structure such as a submerged breakwater, multiple tetrapods are densely collected to form one structure.
- Each of the wave dissipating blocks is required to have sufficient stability against wave force, sufficient structural strength against external force or weight thereof, to be easily lifted and constructed, and to have adequate porosity when the wave dissipating blocks are piled on each other such that wave energy can be reduced.
- the installation method of the wave dissipating blocks includes a two-layer covering type and random piling type, wherein the two-layer covering type includes an upright covering type and an inclined covering type, and the random piling type include an upright shear surface covering type and an inclined shear surface covering type.
- wave dissipating blocks are arranged in an orderly manner and do not significantly impair a surrounding aesthetic despite the arrangement of the wave dissipating blocks which are huge concrete structures, but are difficult to be constructed since whenever installing each of the wave dissipating blocks which weighs dozens of tons, the position and direction (an angle) thereof are required to be adjusted.
- the structure of conventional wave dissipating blocks is installed only in such a manner that the wave dissipating blocks are piled on each other up to the top of the slope of a seafloor along the slope thereof from the seafloor, so it is very difficult to initially align the wave dissipating blocks. That is, in order to align the wave dissipating blocks on the seafloor, many workers are required to descend to the seafloor to align and install the wave dissipating blocks in place. This is a difficult work since the work relies on the skills of the workers on the seafloor on which visibility is not secured, and the risk of accidents on the seafloor is very high.

- a first component may be termed a second component, and similarly, a second component may also be termed a first component.

FIG. 11 is a flowchart of the installation method of a structure to prevent soil loss in the slopes of a river and a coast according to another embodiment of the present disclosure. -
FIGS. 12 and 13 are views illustrating a state in which structures are piled on each other and installed. -
FIG. 14 is a view illustrating the stress distribution of each of the structure of the present disclosure and an existing structure. -
FIG. 15 is a graph illustrating crack loads due to various loads of each of the structure of the present disclosure and the existing structure. - However, most river slopes do not have any measures preventing soil loss in the event of a major flood, so the river slopes easily collapse during a rainy season, resulting in large-scale casualties and property loss.
- Meanwhile, various wastes thrown on a sidewalk flow into a river together with rainwater, and the river is polluted.
- Furthermore, wave dissipating blocks are used to prevent the soil loss and are installed on a part of a breakwater or a shoreline which receives large waves to disperse or dissipate wave energy and to reduce reflected waves, and mainly refer to concrete blocks.
- As a conventional wave dissipating block, a tetrapod having the shape of four horns has been used the most, and a dolos and a sealock made by modifying the tetrapod are also frequently used recently. Particularly, the tetrapod is installed on the slope of a breakwater to form a single layer or double layers, or during the construction of a submerged structure such as a submerged breakwater, multiple tetrapods are densely collected to form one structure. In the breakwater or the bottom of a river in which tetrapods are piled on each other, wave energy is dispersed and dissipated due to a gap between the tetrapods adjacent to each other, the rugged shape of each of the tetrapods, and the interlocking thereof.
- Each of the wave dissipating blocks is required to have sufficient stability against wave force, sufficient structural strength against external force or weight thereof, to be easily lifted and constructed, and to have adequate porosity when the wave dissipating blocks are piled on each other such that wave energy can be reduced.
- Meanwhile, the installation method of the wave dissipating blocks includes a two-layer covering type and random piling type, wherein the two-layer covering type includes an upright covering type and an inclined covering type, and the random piling type include an upright shear surface covering type and an inclined shear surface covering type.
- In the random piling type, it is easy to embody porosity between wave dissipating blocks and it is simple to install the wave dissipating blocks to have an excellent constructability, but huge concrete structures are seen to be piled on each other in disorder to the general public, causing an unsightly scene.
- On the other hand, in the two-layer covering type, wave dissipating blocks are arranged in an orderly manner and do not significantly impair a surrounding aesthetic despite the arrangement of the wave dissipating blocks which are huge concrete structures, but are difficult to be constructed since whenever installing each of the wave dissipating blocks which weighs dozens of tons, the position and direction (an angle) thereof are required to be adjusted.
- Furthermore, irrespective of the shape of a wave dissipating block, the structure of conventional wave dissipating blocks is installed only in such a manner that the wave dissipating blocks are piled on each other up to the top of the slope of a seafloor along the slope thereof from the seafloor, so it is very difficult to initially align the wave dissipating blocks. That is, in order to align the wave dissipating blocks on the seafloor, many workers are required to descend to the seafloor to align and install the wave dissipating blocks in place. This is a difficult work since the work relies on the skills of the workers on the seafloor on which visibility is not secured, and the risk of accidents on the seafloor is very high.

Meanwhile, other expressions describing the relationship between elements, that is, “between” and “directly between” or “neighboring to” and “directly adjacent to”, etc., should be interpreted in a similar manner.
