In the drawings, 1 and 2 are columnar members arranged in parallel in the lateral direction with a predetermined interval,
Reference numerals 3 and 4 designate columnar connecting members that are connected to the columnar members 1 and 2 at right angles to the upper surfaces of the columnar members 1 and 2 on the inside by a predetermined length from both ends of each columnar member. The positions where the columnar connecting members 3 and 4 are arranged are between the center of the columnar connecting members 3 and 4 and the columnar members 1 and 2 as shown in FIG.
If the distance between the centers of the columnar connecting members 3 and 4 is 2 when the shorter distance to both ends of is 1, then
When the wave-dissipating building blocks of the present invention are arranged in a staggered manner as shown in FIG. 6, the distance between the columnar connecting members 3 and 4 becomes constant, making it possible to maintain the wave-dissipating efficiency at any location. can. 3' and 4' are notches formed by cutting out the corner portions of the columnar connecting members 3 and 4 on the columnar member 1 side, respectively. It is formed into a curved shape. 5 is a recess formed on the lower surface of the columnar member 2, and 6 is a shape that engages with the recess 5 formed on the lower surface of the columnar member 2 on the upper surface of the columnar connecting members 3, 4 on the columnar member 2 side.

This was formed to prevent the upper and lower wave-dissipating construction blocks from shifting due to the force of waves when a wave wall is constructed. Reference numeral 7 denotes grooves provided vertically on both sides of the ends of the columnar connecting members 3 and 4 on the columnar member 2 side. This is to prevent waves from directly hitting the sea wall, quay, breakwater, etc. by falling into the groove 7.

Reference numeral 9 indicates that when it is known in advance that the wave-dissipating construction block according to the present invention will be used only for constructing an upright wave-dissipating seawall as shown in FIG. This is a retaining wall formed to close off the ends of the columnar connecting members 3 and 4 on the columnar member 2 side. Reference numeral 10 denotes a notch cut out in the upper surface of the columnar member 1 so that the outer surface side becomes narrower, and has the effect of increasing the rapid contraction effect of waves entering from the columnar member 1 side to the columnar member 2 side. This notch 10 is also formed into a flat or smoothly curved shape like the notches 3' and 4'. Reference numerals 11 and 11' denote a front space above the columnar member 1 and formed between the columnar coupling members 3 and 4; 12 and 12' are above the columnar member 2 and form a front space between the columnar coupling members 3 and 4. 13 and 13' are upper spaces formed between the columnar connecting members 3 and 4, and 14 is the upper space between the columnar connecting members 3 and 4. 4 and is a lower space formed between columnar members 1 and 2. Since the columnar connecting members 3 and 4 are arranged parallel to each other in the vertical direction, when the wave-dissipating construction blocks according to the present invention are connected and constructed in the horizontal direction as shown in FIG. Column-shaped connecting member 3 of wave-dissipating construction block
and the columnar connecting member 4 are parallel to each other in the longitudinal direction.

The wave-dissipating construction block according to the present invention has the above structure, and the method for constructing the wave-dissipating structure will be explained below. First, when constructing an upright wave-dissipating seawall as shown in Fig. 8, the columnar connecting members 3,
The ends of the columnar connecting members 3 and 4 on the columnar member 2 side are closed by dropping drop plates 8 into grooves 7 provided vertically on both sides of the columnar member 2 side of the columnar connecting members 3 and 4. An earth retaining wall 9 is formed integrally with the wave-dissipating construction block according to the invention or the columnar connecting members 3 and 4 and the columnar member 2 to close the ends of the columnar connecting members 3 and 4 on the columnar member 2 side. When constructing a wave-dissipating construction block according to the present invention or a transmission-type wave-dissipating bank as shown in FIG.
The wave-breaking construction block according to the present invention, in which drop plates 8 are not dropped into the grooves 7 provided vertically on both sides of the end of the columnar member 2, is constructed so that the columnar member 1 side faces the wave ingress side. In addition, a plurality of columnar connecting members 3 and 4 are arranged in a horizontal direction and one or two or more rows in a vertical direction so that the longitudinal direction of the columnar connecting members 3 and 4 coincides with the direction of wave ingress. At this time, the columnar coupling members 3 and 4 are arranged so that the distance between the centers of the columnar coupling members 3 and 4 is twice the distance from the center of the columnar coupling members 3 or 4 to the ends of the columnar members 1 and 2. , 4 arranged on the columnar members 1 and 2, the columnar connecting members 3 and 4 of the adjacent wave dissipating construction blocks according to the present invention can be used.
The distance between the centers is also the same as the distance between the centers of the columnar connecting members 3 and 4 of one wave-dissipating construction block, which has the advantage that the wave-dissipating efficiency is constant everywhere. Next, place the wave dissipation construction block on the lower tier so that the adjacent surface of the lower tier wave dissipation construction block is in the center of the upper tier wave dissipation construction block, that is, the lower tier wave dissipation construction block and the upper tier dissipation construction block. The wave building blocks are stacked in a staggered manner. By repeating such operations sequentially from the bottom to the top, it is possible to construct an upright wave-dissipating seawall as shown in FIG. 8 or a permeable wave-dissipating bank as shown in FIG. 7.

When waves enter such an upright wave-dissipating seawall or a permeable wave-dissipating bank, the waves enter the wave-dissipating construction block according to the present invention from the front spaces 11, 11', and the notches 3' , 4' causes a rapid contraction. At this time, if a notch 10 having a narrow outer surface side is formed on the upper surface of the columnar member 1, the wave contraction effect can be further enhanced. Waves flow from the front space 11, 11' to the upper space 13, 1.
3', it flows into the lower space 14 and is diffused, generating turbulent flow and significantly attenuating the wave energy. A portion of the waves flowing into the lower space 14 collides with the wall surface of the columnar member 2, and the direction of the flow is abruptly changed upward or laterally. Wave energy is further attenuated by such rapid contraction, rapid expansion, collision, and the generation of turbulence caused by these.

In this way, the wave energy is rapidly attenuated in each block, but since the blocks are continuous in each direction (up, down, left and right), the upper space 1
3, 13' and the lower space 14 form a waterway that continues in the vertical direction, and the lower space 14 forms a waterway that continues in the lateral direction, so the waves that flow into the block flow in the vertical and lateral directions. It advances while scattering in the waterways. Waves traveling in this direction repeatedly contract and expand rapidly at the joints of each wave-dissipating construction block, and the resulting turbulence effectively attenuates the wave energy. They are forced to do so.

In addition, since each wave-dissipating construction block according to the present invention is subjected to considerable pressure from waves entering from the front side, a recess 5 is formed on the lower surface of the columnar member 2, and the columnar connecting member 3 is , 4 is formed with a convex part 6 having the same shape as the concave part 5 of the columnar member 2, and when constructing a wave-dissipating structure, the convex part 6 of the lower wave-dissipating construction block is
It is desirable to increase the stability of the wave-dissipating construction by engaging the recessed portion 5 of the upper wave-dissipating construction block and stacking them in a staggered manner. In addition, when constructing the wave-dissipating structure as an upright wave-dissipating seawall, use a wave-dissipating construction block in which the earth retaining wall 9 is formed integrally with the columnar connecting members 3, 4 and the columnar member 2 in advance, or It can be constructed using a wave-dissipating construction block in which grooves 7 are formed vertically on both sides of the ends of the columnar connecting members 3 and 4 on the columnar member 2 side, and drop plates 8 are inserted into the grooves 7. .

As described in detail above, the wave-dissipating construction block according to the present invention is composed of a monolithic concrete block having a structure for attenuating wave energy and calming waves, and has an excellent wave-dissipating effect, and has an upright wave-dissipating structure. When used in the construction of breakwaters and upright wave-dissipating seawalls, it has excellent advantages such as improving the calmness in the bay, making ship navigation safer, and improving the efficiency of cargo handling. It has various advantages such as being large in size and having a simple structure, it can be manufactured at low cost, and it is easy to construct.Moreover, by stacking in a staggered manner, it can be used as a wave-dissipating structure with a stable structure. Its industrial value is enormous.
