Description
【発明の詳細な説明】 ＜産業上の利用分野＞ 本発明は浮消波堤装置に関するものである。[Detailed description of the invention] <Industrial application field> The present invention relates to a floating wave levee device.
＜従来の技術＞
浮消波堤装置は、水面に浮体を係留させて、進
行してくる波のエネルギーを消したり、反射させ
たりするのである。<Prior Art> A floating wave levee device moores a floating body on the water surface to eliminate or reflect the energy of advancing waves.
従つて、水面に係留する浮体は安定した位置を
保つことが必要である。 Therefore, it is necessary for floating bodies moored on the water surface to maintain a stable position.
しかし、浮体が波力によつて上下左右に動揺す
るようなものでは、波エネルギーを消す効率が悪
くなる。 However, if the floating body moves vertically and horizontally due to wave force, the efficiency of extinguishing wave energy will be poor.
そこで、石油掘削のリグ等で実施されているテ
ンシヨン・レグ方式を消波構造体として利用する
ことも考えられる。 Therefore, it is conceivable to use the tension leg method used in oil drilling rigs and the like as a wave-dissipating structure.
このテンシヨン・レグ方式は、浮体を係留する
係留索に浮体の浮力分の緊張力を与えて、係留索
を鉛直状に海底にアンカーで固定するものであ
る。 This tension leg method applies a tension equal to the buoyancy of the floating body to the mooring line mooring the floating body, and then fixes the mooring line vertically to the seabed with an anchor.
このように、テンシヨン・レグ方式は、浮体を
係留索の緊張力によつて海底から引つ張ることに
よつて、波力による浮体の動揺を極力小さくし、
効率良く波エネルギーを消すことができる利点を
有している。 In this way, the tension leg method minimizes the movement of the floating body due to wave force by pulling the floating body from the seabed using the tension of the mooring line.
It has the advantage of being able to efficiently eliminate wave energy.
＜本発明が解決しようとする問題点＞
前記した従来の浮消波堤装置には、次のような
問題点が存在する。<Problems to be Solved by the Present Invention> The conventional floating wave device described above has the following problems.
＜イ＞ 前述のテンシヨン・レグ方式は、浮体を
係留索によつて一定の位置に固定するものであ
るから、必然的に固定された浮体にぶつかる波
の衝撃は大きくなる。<A> Since the above-mentioned tension leg system fixes the floating body in a fixed position with a mooring line, the impact of waves hitting the fixed floating body will inevitably be large.
そして、この波の衝撃は、主に大きな揚圧力と
して浮体に作用する。 The impact of this wave mainly acts on the floating body as a large lifting force.
この揚圧力は、第５図に示すように、部材の水
面との位置関係等により異なるが、わずか1.4m
の波高で最大12t／m2もの反力となり浮体に作用
する。 As shown in Figure 5, this uplift force varies depending on the positional relationship of the member with the water surface, but it is only 1.4m.
At a wave height of , a reaction force of up to 12t/ m2 acts on the floating body.
その結果、波の揚圧力によつて浮体が上昇し、
係留索を上方に引つ張る力が、衝撃力として作用
するため、係留索が海底から引き抜けたり、切断
するおそれがあり、安定した浮消波堤を得ること
が困難である。 As a result, the floating body rises due to the uplift force of the waves,
Since the tension that pulls the mooring line upward acts as an impact force, there is a risk that the mooring line may be pulled out of the seabed or cut, making it difficult to obtain a stable floating wave bank.
＜ロ＞ 上記の問題点を解決するために、浮体を
杭で固体する方法がある。<B> In order to solve the above problem, there is a method of solidifying the floating body with piles.
この方法によつて、浮体を安定した状態で一定
の位置に固定できるため、浮体の波力による動揺
はなくなり、効率良く波エネルギーを消すことが
できる。 By this method, the floating body can be fixed in a fixed position in a stable state, so the floating body is not shaken by wave force, and wave energy can be efficiently extinguished.
しかし、この方法では、波エネルギを消す効率
は上がるにせよ、水深の深い所で前記杭を使用す
ることは、資材の面からも施工の面からも経済性
を著しく低下させる。 However, although this method improves the efficiency of quenching wave energy, using the piles in deep water significantly reduces economic efficiency from both the material and construction aspects.
＜本発明の目的＞
本発明は上記のような問題点を解決するため、
次のような浮消波堤装置を提供することを目的と
する。<Object of the present invention> In order to solve the above-mentioned problems, the present invention has the following objectives:
The purpose of the present invention is to provide a floating wave levee device as follows.
＜イ＞ 浮体が受ける波の揚圧力が、係留索に直

ついて説明する。<Structure of the present invention> An embodiment of the present invention will be described below with reference to the drawings.
＜イ＞ 本装置の概要（第１図）
本装置は、浮体１の浮力分の緊張力を与えて海
底にアンカー５をとつた鉛直状の係留索２の上端
を、浮体１に固定した構造である。<A> Overview of this device (Figure 1) This device has a structure in which the upper end of a vertical mooring line 2 with an anchor 5 attached to the seabed is fixed to the floating body 1 by applying a tension equal to the buoyancy of the floating body 1. It is.
固定部６は、浮体１に係留索２を貫通させて、
浮体１の上面に緩衝材３を介して、支圧板４で固
定する。 The fixing part 6 allows the mooring rope 2 to pass through the floating body 1,
A bearing plate 4 is fixed to the upper surface of the floating body 1 via a cushioning material 3.
＜ロ＞ 緩衝材（第１，２図）
緩衝材には、ゴム製の緩衝材３が優れており、
例えば、船舶接岸用のゴムフエンダーの例からも
分かるように、大きな衝撃的エネルギーを吸収す
る能力を有している。<B> Cushioning material (Figures 1 and 2) Rubber cushioning material 3 is excellent as a cushioning material.
For example, as can be seen from the example of rubber fenders for ships berthed, they have the ability to absorb large amounts of impact energy.
また、ゴム製の緩衝材３は引張力には弱いが、
圧縮力には強い性質を有している。 In addition, although the rubber cushioning material 3 is weak against tensile force,
It has a strong compressive force.
ところで、本発明において緩衝材３に作用する
力は、主に波の揚圧力によつて、浮体１が上昇す
るときに発生する圧縮力である。 By the way, in the present invention, the force acting on the buffer material 3 is a compressive force generated when the floating body 1 rises, mainly due to the uplift force of waves.
そのため、ゴム製の緩衝材３は、補強部材とし
て十分な強度と耐久性を有するものである。 Therefore, the rubber cushioning material 3 has sufficient strength and durability as a reinforcing member.
なお、緩衝材３の硬度、厚さ等は、波の揚圧力
に応じて吸収エネルギーを設計して決定すること
ができる。 Note that the hardness, thickness, etc. of the buffer material 3 can be determined by designing absorption energy according to the uplift force of waves.
従つて、あらゆる場合に本装置を使用すること
ができる。 Therefore, the device can be used in all cases.
本発明の緩衝材３には、上記のゴムの他に、合
成樹脂、機械式ばね、空気ばね、水圧ばね等を採
用することができる。 In addition to the above-mentioned rubber, synthetic resin, mechanical springs, air springs, hydraulic springs, etc. can be used for the cushioning material 3 of the present invention.
要するに、緩衝材３が固定部６の補強部材とし
て、十分な耐力を有する材質で構成されていれば
よい。 In short, it is sufficient that the cushioning material 3 is made of a material having sufficient strength to serve as a reinforcing member for the fixing portion 6.
＜ハ＞ 緩衝材の作用（第２図）
緩衝材３は図のように、波の揚圧力によつて浮
体１が上昇したときに、浮体１と支圧板４との間
で圧縮される。<C> Effect of buffer material (Figure 2) As shown in the figure, the buffer material 3 is compressed between the floating body 1 and the bearing plate 4 when the floating body 1 rises due to the uplift force of the waves.
そのため、浮体１が上昇して、係留索２を上方
に引き抜こうとする力を吸収することができる。 Therefore, the floating body 1 rises and can absorb the force of trying to pull out the mooring line 2 upward.
従つて、浮体１が受ける波の揚圧力が係留索２
に直接伝わらずに済むため、係留索２が海底から
引き抜けたり、切断されることがない。 Therefore, the uplift force of the waves that the floating body 1 receives is the mooring line 2
Since the mooring line 2 does not need to be directly transmitted to the ocean floor, the mooring line 2 will not be pulled out from the seabed or cut.
＜その他の実施例１＞ （第３図）
前記実施例の箱体の浮体１の他に、本発明の装
置は、水面に浮遊するフロート７と水中に浮遊す

構成する、傾斜板方式の浮体においても採用する
ことができる。<Other Embodiments 1> (Fig. 3) In addition to the box-shaped floating body 1 of the above-mentioned embodiment, the device of the present invention has a float 7 floating on the water surface and a float 7 floating in the water, which are made of a plate-shaped body. It can also be employed in a floating body of an inclined plate type, which is constructed by connecting wave-dissipating plates 8.
＜その他の実施例２＞ （第４図）
また、本発明の装置によつて、係留索２に作用
する強い衝撃力が減少し、強度と耐久性を有する
安定した浮消波堤が実現できる。<Other Embodiment 2> (Figure 4) Furthermore, with the device of the present invention, the strong impact force acting on the mooring line 2 is reduced, and a stable floating wave bank with strength and durability can be realized. .
そのため、常に鉛直状に一定の形状を保つ係留
索２の内部に、浮体からネツト９等を懸吊して、
いけすや漁礁とするなど、波消し機能と並行し
て、多目的に利用することが可能である。 Therefore, the net 9, etc. is suspended from the floating body inside the mooring line 2, which always maintains a constant vertical shape.
It can be used for multiple purposes, such as as a fish tank or a fishing reef, in addition to its wave-dissipating function.
＜本発明の効果＞
本発明は以上説明したようになるので、次のよ
うな効果を期待することができる。<Effects of the Present Invention> Since the present invention has been described above, the following effects can be expected.
＜イ＞ 浮体と係留索との固定部に、緩衝材を取
り付けたことによつて、浮体が受ける波の揚圧
力が、係留索に直接伝わらなくなつた。<B> By attaching cushioning material to the fixed part between the floating body and the mooring line, the uplift force of the waves applied to the floating body was no longer directly transmitted to the mooring line.
そのため、係留索が海底から引き抜けたり、
切断されることがなくなつた。 As a result, mooring lines may be pulled out of the seabed,
No more disconnections.
従つて、強度と耐久性を有する安定した浮消
波堤を得ることができるようになつた。 Therefore, it has become possible to obtain a stable floating wave bank that has strength and durability.
＜ロ＞ 安定した浮消波堤を得るために、従来の
ように浮体を杭で固定する方法ではなく、係留
索によつて浮体を定位地に固定することができ
る。<B> In order to obtain a stable floating wave bank, the floating body can be fixed at a fixed location using mooring cables, instead of the conventional method of fixing the floating body with piles.
そのため、水深の深い所に浮消波堤を係留さ
せる場合においても、経済的に安価に行うこと
がでるようになつた。 Therefore, even when mooring a floating wave bank in deep water, it has become possible to do so economically and inexpensively.
＜ハ＞ 従来の浮体堤構造には、係留索自体にコ
イルバネやピストンシリンダー等の伸縮部を形
成するものがある。（実公昭47−17575号）。<C> Some conventional floating embankment structures have extensible parts such as coil springs and piston cylinders formed on the mooring lines themselves. (Jikko No. 47-17575).
しかし、この従来技術の場合、係留索自体に伸
縮部を形成するため、施工条件によつて径や長さ
の異なる全ての係留索に伸縮部を加工する必要が
ある。 However, in the case of this prior art, since the extensible portion is formed on the mooring rope itself, it is necessary to process the extensible portion on all the mooring ropes, which have different diameters and lengths depending on the construction conditions.
そのため、そのコストは膨大なものとなつてし
まう。 Therefore, the cost becomes enormous.
それに対して本発明は、係留索自体に緩衝部を
形成するのではなく、係留索とは別体に緩衝材を
作製する。 In contrast, the present invention does not form a buffer part on the mooring cable itself, but instead produces a buffer material separately from the mooring cable.
そのため、係留索の径や長さが異なる場合で
も、緩衝材を転用して用いることができる。 Therefore, even if the mooring ropes have different diameters and lengths, the cushioning material can be reused.
従つて、従来技術のように径や長さの異なる全
ての係留索に伸縮部を加工する必要がないたる、
かなり大幅なコストの削減を達成することができ
る。 Therefore, there is no need to process extensions and contractions on all mooring cables with different diameters and lengths, unlike in the prior art.
Quite significant cost reductions can be achieved.
