Description

[Detailed description of the invention] This invention relates to a breakwater construction block having a shape suitable for constructing a breakwater.

A detached levee is an artificially constructed levee by stacking a large number of blocks offshore a little distance from the shore, and is constructed to make the sea area separated by the shore and the levee a habitat for fish. It is something.

Traditionally, detached breakwaters were constructed using concrete with a trapezoidal cross section, but this required a lot of labor and time, so huge blocks were dropped into the sea from a ship, and then built one after another. A method of accumulating them began to be adopted.
However, in conventional blocks of this type, the upper and lower sides are generally specified, and therefore, when the block is submerged, the work must be carried out while being restrained by the upper and lower positions, which is extremely inconvenient. . In order to do this, it was not only necessary to drop them from the ship, but it required divers to go underwater and correct the hierarchy, which was an extremely inefficient task. Once constructed, the breakwater needs to be a strong structure, and must be strong enough to not be destroyed by waves. Therefore, the blocks for constructing an offshore levee must have a shape that allows for easy installation of the blocks during the construction work, and that allows the blocks to be assembled together firmly after construction. The present inventor had previously developed a block for constructing an offshore breakwater in which identical truncated conical legs were formed on each of the hexagonal sides of a sphere. According to this, although it was very good in eliminating the directionality of the blocks, it was not necessarily possible to strengthen the meshing between the blocks.

Therefore, this idea was created by forming truncated conical legs of different lengths on the hexagonal sides of the sphere, which not only eliminates the directionality of the blocks, but also strengthens the combination of the blocks with each other. It was developed for the purpose of providing building blocks.

Next, an embodiment of the detached levee construction block according to this invention will be described based on the drawings. 1 is a detached levee construction block 1, and this detached levee construction block 1 has a spherical part 2 and a leg part. 3. Legs 3 are formed on the front, back, left, right, top and bottom of the spherical body 2, that is, on the regular hexagonal sides, and each leg 3 is formed into a truncated conical shape, with any leg 3 being longer than the other legs.

Thus, the breakwater construction block 1 is installed in the sea, but since the legs 3 are formed in the hexagonal shape of the spherical part 2, the breakwater construction block 1 has long and short legs. Therefore, there is no need to worry about the orientation at all when installing them, and you can simply stack them one after another in the sea. First, as shown in FIG. 2, blocks 1 in the first row are arranged in the order of A, B, C, and D. When arranging this first row, as long as the blocks A, B, C, and D are arranged next to each other,
Mutual blocks 1 are combined naturally without special consideration. Next, as shown in FIG. 3, the blocks 1 in the second row are installed adjacent to the blocks 1 in the first row in the order of E, F, G, and H. In this case as well, the blocks 1 will naturally combine. In this way, several rows of the first stage are installed. Next, as shown in Fig. 4, the second stage block 1 is I,
Stack J and K on top of the first row in that order.
The detached breakwater construction block 1 has six legs 3, and each pair has different lengths and short legs.
The long legs 3 bite into the structure, making the connection strong, and the detached breakwater as a whole can be easily and strongly constructed. Furthermore, since the leg portions 3 have a truncated conical shape, as the gap between adjacent blocks 1 becomes narrower, the combination becomes stronger. In other words, even if block 1 moves due to waves, the gap between it and the adjacent block 1 becomes smaller, making the combination stronger.Furthermore, since the legs have long and short lengths, it will not fit deeply into the gap between adjacent blocks 1. On the contrary, it becomes difficult to collapse.

As described above, according to the block for constructing an offshore breakwater according to this invention, the directionality of the block is eliminated by having six truncated conical legs, which simplifies the installation work. Since the sections have long and short lengths, the blocks are more closely intertwined with each other, which has the effect of making them less likely to collapse due to waves.
