Description

[Detailed description of the invention] This invention relates to a four-legged concrete block that is placed into the sea near the coast to weaken the waves that hit the shore and prevent erosion of the land by preventing sand from washing away. .

Conventionally, this type of concrete block has generally been of the tetrapot type as shown in FIG.

This invention provides a four-legged block that takes advantage of the advantages of the conventional tetrapot-type block described above while improving the disadvantages of tetrapots, such as easy breakage and monotonous combinations.

Hereinafter, one embodiment of this invention will be explained in detail based on FIGS. 2 to 4. Figures 2 and 3 are a front view and a top view of a four-legged block 1 showing an embodiment of this invention, in which the four-legged block 1 is shown diagonally outward and downward from the four corners of a square base 2 with the same length on each side. A ladder-shaped leg body 3 with a wide lower part is formed, and a thin support column 4 with a narrow tip and a tapered slope is provided upwardly from the center of the table 2.

Further, the bottom surface of the leg body 3 is as shown in FIG.
The leg body 3 is formed into a square with the same length on each side, and the height from the bottom surface of the leg body 3 to the upper end surface of the support column 4 is the height of the leg body 3.
The height of the stand 2 is at least half of the total height.

As explained in detail above, the four-legged block according to this invention has a simple structure and is hard to break, and can be used on coasts, rivers, etc., and can be freely combined as shown in Figure 4, and can weaken the waves that hit the shore. It is possible to prevent sand from being washed away. It is also possible to prevent land erosion and provide shore protection.

Furthermore, the four-legged block based on this invention has slanted legs and a wide base, so there is less sinking into the earth and sand, and since it is installed stably, there is less sand washed away, and it can also be used as a fish nest. There are benefits such as:
