本考案は波のエネルギーを吸収可能な重力式くさび型消
波堤に関するものである。[Detailed Description of the Invention] The present invention relates to a gravity-type wedge-shaped wave-dissipating levee capable of absorbing wave energy.
港湾等に設けられる従来の重力式消波堤は、外側からの
波を反射させてその内側の波を小さくするという型式で
あるため、その建設工数がかさみ、多額の建設費がかる
うえに、潮流の流れをさえぎるため、内側の水質の保全
がはかれないという問題があった。Conventional gravity-type wave-dissipating breakwaters installed in ports, etc. reflect waves from the outside and reduce the waves inside, which increases the number of construction steps and costs, and also reduces tidal currents. There was a problem that the water quality inside could not be maintained because the water flow was blocked.
一方、水質保全をはかるため、浮き消波堤もあるが、そ
の係留等の保守に問題がある。On the other hand, there are floating breakwaters in order to preserve water quality, but there are problems with the maintenance of their moorings.
そこで本考案は、前記従来の問題点を解消するためにな
されたものでであり、重力式くさび型消波堤の波の進行
方向に形成したくさび形状部分における波の反射により
波のエネルギーの吸収をはかると同時に、その消波堤の
枠組に透過した波とその枠組内の塊状消波材との摩擦に
より、波のエネルギーを吸収可能で、更に、大量生産可
能であり、かつ、その設置及び保守の簡単な重力式くさ
び型消波堤を提供することを目的としたものである。Therefore, the present invention was devised to solve the above-mentioned conventional problems, and absorbs wave energy by reflecting the waves at the wedge-shaped part formed in the wave propagation direction of the gravity wedge type wave dissipating dam. At the same time, it is possible to absorb wave energy through the friction between the waves that have passed through the framework of the wave-dissipating dyke and the blocky wave-dissipating material within the framework. Furthermore, it is mass-producible, and its installation and installation process is easy. The purpose is to provide a gravity wedge type wave dissipation levee that is easy to maintain.
即ち、本考案の重力式くさび型消波堤は、波の進行方向
に対してくさび形状を形成する枠組内に消波材を充填し
た複数の消波ブロックにより樹皮される。That is, the gravity-type wedge-shaped wave-dissipating levee of the present invention is comprised of a plurality of wave-dissipating blocks filled with wave-dissipating material within a framework forming a wedge shape in the direction of wave propagation.
以下図面を参照して本考案の実施例を説明するが、第１
図はその重力式くさび型消波堤の消波ブロック３の斜視
図、第２図は第１図の消波ブロック３を複数個配設した
重力式くさび型消波堤の全体斜視図である。Embodiments of the present invention will be described below with reference to the drawings.
The figure is a perspective view of the wave-dissipating block 3 of the gravity-type wedge-type wave-dissipating levee, and FIG. 2 is an overall perspective view of the gravity-type wedge-type wave-dissipating bank in which a plurality of the wave-dissipating blocks 3 of FIG. 1 are arranged. .
まず、第１図の消波ブロック３は、矢印Ｗで示す波の進

リート塊、天然石、その他の消波材１を充填したもので
あり、このような消波ブロック３を第２図のごとく港湾
４等の海中に複数個連続して配設することにより、重力
式消波堤を構成している。First, the wave-dissipating block 3 shown in FIG. 1 is constructed by filling a framework 2 that forms a wedge shape with respect to the wave propagation direction indicated by the arrow W with concrete blocks, natural stones, or other wave-dissipating materials 1. A gravity-type wave-dissipating levee is constructed by arranging a plurality of such wave-dissipating blocks 3 in series in the sea, such as in a port 4, as shown in FIG.
第２図において、波の進行方向Ｗに対向する消波ブロッ
ク３の前面ａは、くさび形状を形成している。In FIG. 2, the front surface a of the wave-dissipating block 3 facing the wave traveling direction W forms a wedge shape.
このように構成された本考案の重力式くさび型消波堤で
は、枠組２に形成されたくさび形状部分における波の反
射によって波高を大きくし、波を砕すが、この枠組を透
過した波とその内部の消波材１との摩擦によって波エネ
ルギーを吸収することができる。In the gravity-type wedge-shaped wave-dissipating levee of the present invention constructed in this way, the wave height is increased by reflection of the waves at the wedge-shaped portion formed in the framework 2, and the waves are broken. Wave energy can be absorbed by friction with the wave-dissipating material 1 inside.
即ち、上記くさび形状部分における波の反射及び透過の
繰り返しによって波エネルギーは吸収される。That is, the wave energy is absorbed by the repetition of wave reflection and transmission in the wedge-shaped portion.
なお、このような消波ブロック３をＰＣハイブリッドで
製作することにより大量生産可能である。Note that mass production is possible by manufacturing such a wave dissipating block 3 using a PC hybrid.
なお、上記枠組２は波を透過するものならばどのよなも
のでも良く、例えばネット状の枠組２でも良い。Note that the framework 2 may be of any type as long as it transmits waves; for example, a net-like framework 2 may be used.
従って、本考案の重力式くさび型消波堤を構成するこの
ような消波ブロックをある単位造っておけば、大量生産
ができ、この消波ブロックにかかる外力も従来の重力式
消波堤に比較してかなり小さいため、海底に置くだけで
良いので、その設置も簡単であり、保守も不要であると
いう利点がある。Therefore, if such wave-dissipating blocks constituting the gravity-type wedge-shaped wave-dissipating dam of the present invention are manufactured in a certain unit, mass production is possible, and the external force applied to these wave-dissipating blocks is also less than that of the conventional gravity-type wave-dissipating block. Since it is relatively small, it only needs to be placed on the seabed, so it has the advantage of being easy to install and requiring no maintenance.
また、本考案の重力式くさび型消波堤では、海水が通過
するので、消波堤の内側の水質保全もはかり得るという
利点がある。Furthermore, the gravity-type wedge-shaped wave-dissipating levee of the present invention has the advantage that, since seawater passes through it, the water quality inside the wave-dissipating levee can be maintained.
更に、波の反射の過程で波エネルギーを吸収するため、
反射波がさく、透過波を小さくすることができる。Furthermore, in order to absorb wave energy in the process of wave reflection,
Reflected waves are strong, and transmitted waves can be made small.
