Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wave-dissipating structure for depositing wave-dissipating materials such as stones and concrete blocks, and a wave-dissipating structure using the same.

[0002]

2. Description of the Related Art Conventionally, rubble stone foundations for protecting wave-dissipating structures used for revetments such as rivers and coasts, and wave-dissipating works installed in front of the wave-dissipating structures are washed with waves or running water. It was easily excavated and collapsed, and could not fully protect the wave-dissipating structure. On the other hand, assuming a scouring depth that is expected to be scoured by waves, running water, etc. in advance, digging the water bottom ground in advance and then throwing rubble stones to wash it by waves, running water, etc. There is a rubble stone construction method that tried to make digging less likely.

However, in the above-mentioned rubble construction method, the scouring depth is assumed to be deeper than it actually is, and it is easy to assume large waves, running water, etc., resulting in an excessively safe design, resulting in a high construction cost and a long construction period. There was a drawback that it was easy to invite.

The applicant of the present invention has previously proposed that, in order to solve the above-mentioned various drawbacks, a lattice-shaped wave-dissipating laying material and a wave-dissipating structure using the same (Japanese Patent Application Laid-Open No. 57-19406 / Patent No. 1295).
No. 515), a lattice-shaped wave-dissipating construction body (Shokai Sho 62-2642)
No. 6 / utility model registration No. 1756392) was developed and proposed.

[0005]

The former is constructed by laying a grid-like laying material on a sandy water bottom ground, and laminating and depositing wave-absorbing materials such as stones and concrete blocks on it. By this, even when the sand below the wave-eliminating material is scoured by waves, the load is distributed to the grid-like laying material so that the grid-like laying material sinks evenly. .

[0006] However, in the case of a submerged ground in which the remains of the existing wave breaking material are buried in the sand or a hard submerged ground such as cobblestone or rock, the wave breaking material on the grid-shaped laying material rides on them. And, only that part does not sink together with other wave-dissipating materials, and at the place where the slope of the seabed is steep, the blocks etc. accumulated on the top are likely to fall and dissipate. Met.

In the latter case, a wave-dissipating structure can be constructed by laying a lattice-shaped wave-dissipating laying body on a sandy water bottom ground and inserting a wave-dissipating material into the lattice-shaped wave-dissipating laying body. , Even when the slope of the submarine ground is steep, the side wall can prevent the wave-dissipating material deposited on the top from falling.
Although it has the advantage of high stability, in the same way as the former case, in the case of a water bottom ground where the remains of the existing wave breaking material are buried in the sandy water bottom ground, or a hard water bottom ground such as boulders and rocks. The bottom plate itself acts so as to cut an edge between the water bottom ground and the wave-dissipating material deposited on the bottom plate,
There was a problem that the wave-dissipating structure itself did not fit in smoothly with the subterranean ground.

[0008] Therefore, the present invention is to make the debris of the wave-dissipating material buried in the sandy submerged ground, or even in the case of a hard submerged ground such as boulders and rocks, to make them blend smoothly with those submerged grounds. The present invention intends to provide a wave-dissipating laying body and a wave-dissipating structure using the same.

[0009]

The constitution of the wave-dissipating structure A of the present invention is as follows. The bottom plate B has a pair of inner vertical rods 4, 4 and inner horizontal rods 5, 5 spaced apart from the outer vertical rods 1, 1 and the outer horizontal rods 2, 2 which are connected in the form of a square. The openings b, which are larger than the wave-dissipating material S, are defined in parallel and are arranged between the outer vertical rod 1 and the inner vertical rod 4 and between the outer horizontal rod 2 and the inner horizontal rod 5 which are opposed to each other. The partition rods 6 are provided so as to partition and form, around the opening b, grid-like meshes b ′, b ″ having a size that allows the wave-eliminating material S to be engaged without coming out. The rod 8 and the horizontal bridging rod 9 are arranged vertically and horizontally at a required interval to define grid-like stitches c, c'of a size with which the wave-eliminating material S is engaged without coming out. The side wall body C is provided along the outer vertical rods 1 and 1 and the outer horizontal rods 2 and 2 of the bottom plate body B.

In the wave-breaking structure D of the present invention, the wave-breaking material S is engaged with the lattice pattern b'of the above-mentioned bottom plate B, and the wave-breaking material S causes the above-mentioned opening b of the bottom plate B to be caught. In addition, another wave-dissipating material S is crosslinked and held.

[0011]

DETAILED DESCRIPTION OF THE INVENTION A wave-dissipating structure A as a first embodiment of the present invention will be described with reference to the drawings. B is a bottom plate, which is an inner vertical rod 3, with an outer vertical rod 1, 1 and an outer horizontal rod 2, 2 connected in a plane rectangular shape with a space therebetween.
3 and the inner horizontal rods 4 and 4 are juxtaposed to form an opening b larger than the wave-dissipating material S, and the space between the adjacent outer vertical rod 1 and the inner vertical rod 3 and the outer horizontal rod 3 are provided. Rod 2 and Uchiyoko rod 4
A partition rod 5 is erected between and, and around the opening b, the grid-like meshes b ′, b ″ of a size such that the wave-eliminating material S shown in FIG. (Figs. 1 and 2), and the connecting portions of the rods or the joined portions where they intersect are fixed by welding, bolting, etc. In addition, 6 is an outer vertical rod 1 and an inner vertical rod which are adjacent to each other. It is a reinforcing member which is laid across between the rod 3 and between the outer lateral rod 2 and the inner lateral rod 4.

As the inner and outer vertical rods 3, 1, the inner and outer horizontal rods 4, 2, and the partition rod 5, those made of shaped steel, steel pipes, rebar / steel concrete, or those subjected to anticorrosion / abrasion resistant treatment are used. it can.

The size of the opening b is set as follows (FIG. 3). First, the length of the outer rod 2 is L, the length of one side of the grid pattern b'is L ₁ , the length of one side of the opening b is L ₂ ,
Wave-dissipating material S (shown as S _{1 to} S ₉ ) placed on the bottom plate B
Let each weight be W _{1 to} W ₉ . Length of one side of opening b L ₂
Can be approximately expressed by the following equation. L ₂ = L−2L ₁ (1) Further, the length L ₁ of one side of the lattice pattern b ′ is shorter than the short side of the wave breaking material S. As a result, the wave-eliminating material S does not come out from the lattice-shaped mesh b ′ or the lattice-shaped mesh b ″. In the wave-dissipating laying body A having the above-described bottom plate B, two layers are stacked and stacked. The following forces act on the wave-eliminating materials S _{1 to} S ₉ to be in a stable state.

As shown in FIG. 3, S ₁ , S ₃ , S ₅ , S
_When each of the lower wave-dissipating materials indicated by ₄ and S ₂ is submerged in the sandy water bottom ground G, each of the wave-dissipating materials has a buoyancy equal to the weight of the sand and the water that they have respectively removed. Work, which significantly reduces the apparent weight of each wave breaker at the bottom. In addition, the lower wave-eliminating materials S ₁ , S ₃ , S ₅ ,
Lateral forces indicated by P ₁ and P ₂ are generated in S ₄ and S ₂ , respectively, at the portions in contact with the adjacent wave canceller.

The lower wave-eliminating materials S ₁ , S ₃ , S ₅ , S
_4, of the S _2, lattice-shaped eyes b ', b' wave dissipating member engaged with the S _1, Shonamizai S ₃ that the S ₂ is sandwiched from both sides located on the opening b, S _5, S ₄ Is subjected to a large frictional resistance between the wave-dissipating materials S ₁ and S ₂ engaged with the lattice-like meshes b ′ and b ′ and between them, and the upper stage where sand buoyancy is not acting on them. Wave-eliminating material S ₆ , which is deposited on the
Load _{W 6, W 8, W 9} , W 7 of S _8, S _9, S ₇ is applied.

As a result, the wave canceling material S located on the opening b
₃ , S ₅ and S ₄ try to escape to the lower side of the opening b, but between the wave-eliminating materials S ₁ and S ₂ arranged on the lattice-like meshes b ′ and b ′ and their wave-eliminating properties. The upward force generated by the frictional resistance between the materials S ₃ , S ₅ , and S ₄ and the apparent weight thereof cancel each other out. In other words, Shonamizai S _3, S _5, S ₄ located on the opening b is in a state of being sandwiched between the grid-like eyes b wave dissipating member engaged with the 'S _1, S _2, between them Since the forces acting on the openings b are balanced and stable, the wave-eliminating members S ₃ , S ₅ , S ₄ located on the openings b are held in a bridge state above the openings b without being supported by the bottom plate B, Therefore, it does not escape to the lower side.

C is a side wall body, and the structure thereof is as follows. 7 is a standing rod having a height approximately twice the length of one side of the grid-like eye b ', and the length of one side of the grid-like eye b'or the grid-like eye b "is provided on the periphery of the bottom plate B. The standing rods 7 are arranged at equal intervals, that is, the standing rods 7 are the connecting portions of the outer vertical rods 1 and the outer horizontal rods 2, the outer vertical rods 1, the inner horizontal rods 4, and the outer horizontal rods 2.
At the inner corners of the joints between the inner vertical rod 3 and the outer vertical rod 1 and the partition rod 5, the lower ends thereof are connected and fixed by welding or bolting. The height of the standing rod 7 is not limited to the height of about twice the length of one side of the grid-like b ',
It may be set at an arbitrary height, or may be connected and fixed only to the outer vertical rod 1 and the outer horizontal rod 2.

Reference numeral 8 is a horizontal rod, which is horizontally attached to the leading end and the intermediate portion of the standing rods 7 arranged in a row as described above, and is fixedly connected by welding or bolting. Similarly to the grid-shaped eye b ′ formed around the opening b of the body B, the grid-shaped eyes c and c ′ having the size with which the wave-dissipating material S can be engaged without coming off are defined. In addition,
The horizontal position of the horizontal rod 8 is not limited to the tip portion and the intermediate portion of the standing rod 7, and may be set at any position.

A wave-dissipating structure using the above-mentioned wave-dissipating structure A will be described with reference to FIGS. The wave-dissipating structure D shown in FIGS. 4 and 5 is constructed by laying the wave-dissipating structure A on the submarine ground G, and laminating the wave-dissipating material S therein in the manner described above. The height of the side wall body B of the wave-dissipating structure A is h.

When the wave-dissipating structure A is laid on the submarine ground G,
The wave-dissipating structure A immediately sinks into the water bottom ground G by the sinking distance h ₁ due to its own weight.

When the water bottom ground G below the wave-dissipating structure A is scourd after the wave-disintegrating material S has been put in, the whole wave-dissipating structure A sinks by the sinking distance h ₂ . At this time, the wave-dissipating structure A
The settlement distance K ₁ of can be expressed by equation (2). K ₁ = h ₂ −h ₁ (2) Further, the absolute settlement distance K of the wave canceling material S located on the opening b at that time can be expressed by the equation (3). K = K ₁ = h ₂ −h ₁ (3) Here, h = 1.8 m, h ₁ = 0.6 m, h ₂ = 1.5
Assuming m, the settlement distance K ₁ of the wave-dissipating structure A can be expressed by equation (4). _{K 1 = h 2 -h 1 =} 1.5-0.6 = 0.9m ... (4) absolute subsidence distance K Shonamizai S located on the opening b is
From the expressions (3) and (4), K = S ₁ = 0.9 m (5)

The meanings of the expressions (2) to (5) mean that when the wave-dissipating structure A sinks for a certain distance, the wave-dissipating material S deposited on the wave-dissipating structure A is also integrated with the wave-dissipating structure A. It is to sink by the same distance. As a result, even if the opening b is sectioned in the wave-dissipating structure A, the wave-dissipating material S in the wave-dissipating structure A is formed.
Does not fall off from the opening b, and the opening b
The wave-dissipating structure D is formed by partitioning the
To become familiar with. Furthermore, the wave-dissipating structure D
The state in which the water-dissipating structure A is adapted to the subseabed ground G can be maintained even when the wave-dissipating construction body A sinks to the subseabed ground G.

The total weight of the wave-dissipating structure A and the wave-dissipating material S is about 100t to 200t, and the wave-dissipating structure D does not move horizontally on the seabed G even by strong waves. Even if the wave-dissipating structure A is inclined by scouring, the side-wall body C of the wave-dissipating material S filled in the wave-disintegrating material S does not dissipate and is not dissipated.

Although the design criteria for harbors, fishing ports, etc. specify that the thickness of the wave breaking material S is 1.5 m or more, (2)-
As shown in the equation (5), the wave-dissipating structure D is constructed so as to meet the regulation.

FIG. 6 shows an example in which the wave-dissipating structure D is applied to solidify an underwater structure E. The wave-dissipating structure D is supported at its base on a water bottom ground G such as a river. Along the side walls of the foundation body of the bridge pier or the breakwater 9 such as a pile frame type breakwater, which are arranged so as to be separated from each other by several meters (for example, 2 to 3 m), respectively. The discarded stone 10 is deposited in the meantime.

As a result, even if the wave-dissipating structure D sinks due to scouring, the wave-dissipating material S sinks integrally with the wave-dissipating laying body A and does not scatter, and the area around the base of the dam body 9 is prevented. It becomes possible to prevent the bottom ground G from being scourd by running water or waves of a river. Further, even if the wave-dissipating structure D is inclined by scouring, the side wall C of the wave-dissipating structure A prevents the wave-dissipating material S from flowing out and is not scattered.

FIG. 7 shows an example in which the wave-dissipating structure D is applied to a rubble mixed dike F. The wave-dissipating structure D is arranged in two rows on the offshore side and the land side, and further offshore. On the side, the wave-dissipating structures D are stacked in two steps, and on the land side, the wave-dissipating structures D are stacked in three steps and arranged, and the stones 10 are evenly distributed between the two rows of the wave-dissipating structures D. , And an upright bank 11 such as a concrete caisson is placed on top of this and the deformed wave-dissipating material 12 is deposited on it.

As a result, even when the wave-dissipating structure D sinks due to scouring, the wave-dissipating material S sinks integrally with the wave-dissipating structure A and does not scatter. It becomes possible to prevent the thrown away stone 10 from being scattered and the upright bank 11 from tilting. Further, even if the wave-dissipating structure D is inclined by scouring, the wave-dissipating material S is prevented from being dissipated by being blocked by the side wall body C of the wave-dissipating structure A.

FIG. 8 shows an example in which the wave-dissipating structure D is applied to the artificial reef F. The wave-dissipating structure D is arranged in two rows on the offshore side and the land side, and the wave-dissipating structures D Structure D 3
This is a structure in which the stone blocks 10 are stacked in a row and arranged, the trapping stones 10 are trapezoidally deposited between the two rows of the wave-dissipating structures D, and the coating block 13 is formed on the upper surface thereof.

As a result, even if the wave-dissipating structure D sinks due to scouring, the wave-dissipating material S sinks integrally with the wave-dissipating structure A and is not scattered. It is possible to prevent the thrown away stone 10 from being scattered. Further, even if the wave-dissipating structure D is inclined by scouring, the wave-dissipating material S is prevented from being dissipated by being blocked by the side wall body C of the wave-dissipating structure A.

FIG. 9 shows a wave-breaking structure for the restoration of the submarine ground G in which the existing wave-breaking material using the wave-breaking materials 14 has collapsed and the wave-breaking materials 14 are buried in the sand. This is an application of D, and has a construction in which the wave-dissipating structure A is placed on the irregular-shaped wave-dissipating material 14 which is scattered, and the wave-dissipating material S is deposited and deposited thereon.

As a result, the existing irregular wave-dissipating material 1 scattered
Since the wave force can be weakened by the wave-dissipating structure D while pressing 4 from above, it is possible to prevent further scattering of the existing deformed wave-dissipating material 14, and the wave-dissipating structure D itself. Stabilize.

Next, a second embodiment of the wave-dissipating structure of the present invention will be described with reference to FIGS. 1 and 2 above
In the above, the wave-dissipating laying body A having a shape in which the bottom plate body B has a planar rectangular shape has been described. However, the wave-dissipating laying body H is different in that the bottom plate body I has a substantially triangular shape in a plane.

The structure of the bottom plate I is as follows. The one ends 15a and 15a of the two outer rods 15 and 15 are connected to each other, and the outer rod 17 is connected between the other ends 15b and 15b via the connecting rods 16 and 16 to form a substantially planar triangle. Further, the inner rod 18 is arranged in parallel with the outer rod 17 with a space therebetween, and the opening Ia larger than the wave-eliminating material S is formed.
Are formed. Further, a plurality of partition rods 19 are provided between the outer rod 17 and the inner rod 18 to form a grid-like mesh Ib of a size with which the wave-eliminating material S is engaged without coming out. Then, the connecting portions of the rods or the joined portions that intersect each other are connected and fixed by welding, bolting, or the like.

Numeral 20 is a standing rod having a height approximately twice the length of one side of the grid-like mesh Ib, and is arranged on the peripheral edge of the bottom plate I at the same intervals as the length of one side of the grid-like mesh Ib. are doing.
That is, the upright rod 20 includes the one end portions 15 a, 1 of the outer rod 15.
5a connecting portion, the other end 15 of the outer rod 15,15
b, 15b and connecting rods 16, 16 connecting portion, outer rod 17
And the connecting rods 16, 16, the connecting portion, the outer rod 17 and the partition rod 1
The lower end is fixed to the inner corner of the connecting portion with 9 by welding or bolting. The height of the upright rod 20 is not limited to the height approximately twice the length of one side of the grid-like eye Ib, and may be set to any height.

Reference numerals 21 and 21 denote horizontal rods, which are horizontally attached to the leading end portion and the intermediate portion of the standing rods 20 arranged in a row as described above, and are connected and fixed by welding or bolting. , The grid pattern I formed by partitioning on the bottom plate I
Similar to b, the side wall body J is formed by partitioning and forming the grid-like mesh Ja of a size with which the wave-eliminating material S is engaged without coming out. The horizontal position of the horizontal rod 21 is not limited to the tip portion and the intermediate portion of the standing rod 20, and may be placed at any position. In the wave-dissipating structure using this wave-dissipating structure H,
The wave-dissipating material located on the opening Ia is formed by the lattice pattern J of the side wall body J.
In the state of being sandwiched between the wave-eliminating member engaged with a and the wave-eliminating member engaged with the lattice pattern Ib of the bottom plate body I, the forces acting between them are balanced and stabilized. As a result, those openings Ia
The upper wave-dissipating material is held in a bridge state above the opening Ia without being supported by the bottom plate body I, and therefore,
There is no escape below.

In FIG. 12, the wave-dissipating material S is attached to the wave-dissipating structure H.
Three wave-dissipating structures K formed by depositing (not shown)
A large number of irregularly-shaped wave-dissipating materials 22 scattered on the water bottom ground G.
The curved lines are arranged adjacent to each other along the curved line. As a result, the scattered wave-breakers 22 can be pressed down from above and the wave force can be weakened by the wave-breaking structures K, so that further scattering of the wave-breakers 22 can be prevented. .

A wave-dissipating installation body H'as a third embodiment shown in FIG. 13 is a partition rod 19 of the wave-dissipating facility body H shown in FIG.
The arrangement of the partition rods 19 is different, and the partition rods 19 are arranged between the outer rod 17 and the inner rod 18 so as to form a plurality of planar triangular eyes Ib '. . The same components as those described in FIG. 12 are designated by the same reference numerals and the description thereof is omitted.

The present invention is not limited to the above-described embodiments, but can be implemented in various forms within the scope of the gist thereof. In FIGS. 1 and 2, the wave-dissipating structure in which the grid pattern is formed around the entire circumference of the opening has been described, but the grid pattern may be formed at least on one side or more of the opening.

In FIGS. 10 and 11, one inner rod out of three outer rods connected so as to have a triangular planar shape is provided with the inner rods in parallel with each other at a required interval. In addition to forming an opening larger than the corrugated material, a partition rod is installed between the outer rod and the inner rod, which are opposed to each other by the above-mentioned arrangement, so that the wave-dissipating material can be engaged without slipping out. Although the bottom plate body in which the partition is formed is described, as the bottom plate body, a required space is provided for at least one outer rod of the plurality of outer rods connected so as to have a required planar shape such as a triangle. The inner rods are arranged side by side to form an opening larger than the wave-eliminating material, and the partition rods are installed between the outer rod and the inner rod facing each other by the above-mentioned arrangement, so that the wave-eliminating material can escape. It suffices that the lattice-shaped meshes are sized so as to engage with each other.

[0041]

According to the present invention, since the opening is defined in the bottom plate of the wave-dissipating structure, the edge between the wave-dissipating material accumulated on the wave-dissipating structure and the water bottom ground is cut. There is no. As a result, even if the remains of existing blocks are buried in the sandy ground, or even if it is a hard waterbed ground such as cobblestone or rock, it is possible to adapt the wave-dissipating structure to the waterbed ground and stabilize it. it can.

Since the wave-dissipating material arranged on the opening is bridged and held by the wave-dissipating material placed on the grid pattern of the bottom plate, the wave-dissipating material can escape to the lower side of the opening. Therefore, even when the wave-dissipating body sinks to the seabed, it does not hinder the compatibility between the wave-dissipating structure and the seabed.

Even when a wave-dissipating structure is laid on a submerged ground having a slope, the wave-dissipating member can be locked by the side wall of the wave-dissipating structure, so that the wave-dissipating member cannot be easily dropped off. .
