Description

[Detailed description of the invention] Industrial applications The present invention relates to wave absorbing and dissipating blocks.

Conventional technology As a conventional wave absorbing and dissipating block, i-trabond (
(registered trademark) is common. It consists of concrete blocks formed into a star shape with 41 protrusions forming an angle of 120 degrees with each other, and the embankment body is constructed by stacking a plurality of these blocks.

Problems to be Solved by the Invention However, with such conventional blocks, the embankment body is constructed by simply stacking a plurality of these star-shaped blocks, so it is difficult to create a regular shape of the embankment body. The problem is that it is a national crisis. Another problem is that when strong waves collide with each other, the blocks may become misaligned and the shape of the embankment body may be disturbed.

Therefore, an object of the present invention is to solve such problems and to provide a wave absorbing and dissipating block that can construct an embankment body with a regular shape and that does not cause disturbances in the shape of the embankment body. do.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has been developed by using square tl-shaped blocks that are arranged laterally from the outside of the bay to the inside of the bay and can be stacked in plural to construct an embankment body. Inside,
A through hole for the ura wave going from the outside of the bay to the inside of the bay is formed, a convex part is formed on at least one side of the square pillar of the block, and a convex part is formed on at least one side of the square pillar of the block. A concave portion into which a convex portion of another block can be fitted is formed on another side surface opposite to the side surface of the block.

Function: According to this configuration, waves propagating from the outside of the bay toward the inside of the bay are dissipated by passing through the through hole. Therefore, by stacking a plurality of these blocks, 414 embankments with a regular shape such as a rectangular parallelepiped are constructed. In addition, the convex portions and concave portions of adjacent blocks are
By fitting these blocks together, the connection between these blocks becomes strong, and an embankment body is constructed in which the blocks do not shift even in the event of strong waves colliding with each other.

Actual example Fig. 1 shows a wave absorption wave amplifier based on the present invention.
Here is an example of this. This block 'C-2G' is made of concrete material in the shape of a square prism, and four sides 3, 4, 5, and 6 appear on the outside of the block. On one side surface 3, a plurality of convex portions 7 of a constant height each having a constant length are provided at constant distances in the length direction of the block 2.
is formed. Each convex portion 7 is a side surface 3 of a square prism.
It is formed over the entire width of the On the side surface 5 located opposite to the side surface 3 on which the convex portion 7 is formed, a concave portion 8 corresponding to the convex portion 7 is formed over the entire width of this side surface 5, and when a plurality of blocks 2 are stacked, The structure is such that the convex portions 7 and concave portions 8 of adjacent flocks 2 fit into each other.

FIG. 2 shows another embodiment of the present invention (in this figure, a pair of adjacent side surfaces 3 and 4 are each formed with a convex portion 7, and another pair of adjacent side surfaces 5 and 6 are formed with a convex portion 7). A recess 8 may be formed in each.

A cast iron pipe 9 extending in the length direction of the block 2 is embedded inside the block 2, and a through hole 10 is formed by this VI iron pipe 9. This through hole 10 is located on the right side of a bellmouth-shaped suction port 12 that opens at the outer end face 11 of the block 2 .

Further, in a portion of the cast iron pipe 9 on the inner side of the bay than the suction port 12, a small diameter portion 13 having a smaller diameter than the suction port 12 is formed over a fixed length. A large-diameter portion 14 having a larger diameter than the small-diameter portion 13 is formed in a portion of the cast iron pipe 9 at the inner side of the small-diameter portion 131 . The small diameter portion 13 is connected to the large diameter portion 14 via a connecting portion 15, and the connecting portion 15 is shaped like an iron ball so that the diameter gradually increases from the small diameter portion 13 to the large diameter portion 14. is formed. The large diameter portion 14 is configured such that the inner end 16 of the large diameter portion 14 opens at the inner end surface 17 of the plug 2.

FIG. 3 is a cross-sectional view of a breakwater 18 as a breakwater body constructed by stacking a plurality of wave-dissipating blocks 1.

Here, 19 is a closed part that is installed on the seabed 20, and 21 of this base part 19 has an upward slope from the outer side 22 of the bay to the inner side 23 of the bay. It is formed like j.

The wave-dissipating blocks 1 are stacked on top of the top surface 21 of the base portion 19, and are arranged so as to have an inclination J like the top surface 21. Above the wave-dissipating block 1 at the top, a mounting section 24 is arranged 1i11♂.

The soil surface 25 of this 1-soft part 24 is configured to be horizontal against the inclination of the wave-dissipating block 1, and is designed to allow people, vehicles, etc. to pass through. The base portion 19 and the upper portion 24 are also formed with a convex portion 7 and a concave portion 8, and are configured to fit into the concave portion 8 and the convex portion 7 of the wave-dissipating block 1.

FIG. 4 shows a breakwater 18 having a configuration similar to that shown in FIG.
FIG.

As shown in the figure, each wave-dissipating block 1 is arranged to have a rhombic shape when viewed from the end. Uranami block 1 and foundation 19
As shown in FIG.
A spacer 26 with a vertical angle has been installed. This spacer 2
6 is formed with a recess or a convex portion that fits into the convex portion 7 or recess 8 of the wave-dissipating I[1], and FIG. .

When building a breakwater on the first day, first place the foundation part 1 on the seabed 20.
9 is formed, and a plurality of wave-dissipating blocks 1 are stacked on this base portion 19. At this time, the Uranami blocks 1 are stacked with the U-shaped concave portions 8 and the convex portions 7 fitted together, so that the Uranami blocks 1 are stacked with the U-shaped convex portions 7 aligned, for example, as shown in FIG. Therefore, when the wave-dissipating blocks 1 are stacked diagonally as shown in FIG.
Since it is formed over the entire width of the area, it is in a continuous state as shown in the figure. Therefore, the next Uranami block 1A
When stacking up the wave-dissipating block 1A shown in the figure, with the concave part 8 of the wave-dissipating block 1A fitted with the continuous convex part 7 as described above, set the wave-dissipating block 1A downward. You can easily work by simply turning the button.

If a predetermined number of wave-dissipating blocks 1 are accumulated,
By installing the soft part 24 on the offering part, the breakwater 1
8 is completed - Ruru.

In this way, each wave-dissipating I-lock 1 is stacked by fitting the q convex portions 7 and concave portions 8, so that it can be firmly connected to the breakwater 18 with excellent strength. 4M can be built.

Furthermore, even if the wave-dissipating blocks 1 are stacked at an angle as shown in FIG. 3, the fitting between the convex portions 7 and the concave portions 8 prevents the debris from falling to the outer side 22 of the bay.

Another advantage is that even if strong waves collide, the wave-dissipating blocks 1 do not become misaligned with each other. Furthermore, since the wave-dissipating blocks are formed in the shape of a square column, the breakwater 18 constructed by stacking them can be finished in a regular shape without extreme unevenness or bending, resulting in a beautiful appearance.

As mentioned above, if the Uranami blocks 1 are stacked in a diamond shape when viewed from the end, the construction work of the breakwater 19 can be easily carried out, and the lower part is The stress in the vertical direction transmitted to the Uranami block 1 can be laterally dispersed. In addition, it is possible to obtain a large drag force against the buoyant force exerted by waves9.Also, as shown in Fig. The work can be easily carried out by simply removing the other wave-dissipating blocks 1 in a V-shape such that this wave-dissipating block 1B forms a trough.

In addition, the reconstruction of the breakwater 18 that follows A can be easily done in the same manner as in 9-1.

In addition, since the through-hole 10 of the wave-dissipating block 1 is formed of a cast iron pipe 9, the wave-dissipating block 1 can be easily formed by simply placing a concrete around the cast iron pipe 9. 9 allows the block 2 to be reinforced by C'.

If waves advance from the outside 22 of the bay to the breakwater R18 (not shown in FIG. 3), these waves will pass through the suction port 12 and pass through the through hole 1.
0, the energy is absorbed and dissipated by colliding with the inner surface of the through hole 10 and by changing the cross-sectional area of the passage inside the through hole 10. In addition, a water current based on the waves is generated inside the through hole 10, and when the waves return to the outer side 22 of the bay, a water current is generated due to the slope of the through hole 10. Retention can be prevented.

FIG. 8 shows another example of the breakwater 18.

In this example, the through-hole 10 formed inside the block 2 is formed so that the through-hole 9 and the through-hole 10 shown in FIGS. 1 and 3 are arranged almost mirror-symmetrically. That is, the through hole 10 has a second connecting portion 27 following the large diameter portion 14, which is longer than the one shown in FIG.
and a second small-diameter portion 28, and a discharge port 29 extending from J5 to 171JO is formed in the second small-diameter portion 28 at the end surface of the inner side of the bay of the block 2.

With this configuration, the through hole 10 can be made longer than those shown in FIGS. 1 and 3, and the number of changes in its cross section can be increased, so that the Uranami effect can be further improved. can.

Effects of the Invention As described above, according to the present invention, when constructing an embankment body by stacking a plurality of blocks, since these blocks are formed in the shape of a square prism, the curved embankment body can be finished in a regular shape such as a rectangular parallelepiped shape. , and the adjacent p[I
