Description
【０００１】[0001]
本考案は、展張自在な消波部材を用いた消波装置に関する。 The present invention relates to a wave breaking device using a wave breaking member that can be freely stretched.
【０００２】[0002]
従来の消波方法としてはいくつかの方法を挙げることができる。例えば、防波 堤、防波護岸、消波桟橋、浮消波堤などがある。このうち防波堤、消波護岸、消 波桟橋は構造物を海底に固定する方法のものであり、浮消波堤は構造物を海面に 浮上させて消波を行うものである。この浮消波堤と同様に、海面で消波させる方 法に、図４に示すような、消波シートがある。 There are several conventional wave-dissipating methods. Examples include breakwaters, breakwaters, breakwater jetties, and floating breakwaters. Of these, breakwaters, breakwaters, and breakwater piers are the methods of fixing structures to the sea floor, and floating breakwaters are to lift the structures above the sea surface to break the waves. Similar to this floating breakwater, there is a wave breaking sheet as shown in Fig. 4 as a method to break the wave at the sea surface.
【０００３】 この消波シートは、まず、波に直交する方向に２本の側ロープ１、１を平行に 設置する。この側ロープ１の浮き２が設けられた端部には、他端部にアンカー３ を設けた連結ロープ４が繋止されており、前記アンカー３は海底に投下されてい る。また、前記側ロープ１と交差するようにして、消波シートの外周要部を繋止 するための側張５、５…を配置する。これらの側張５はその端部には、他端部に アンカー３を設けた連結ロープ４が繋止されており、前記アンカー３は海底に投 下されている。また、この側張５と前記側ロープ１とが交差する部分には浮き２ が設けられている。そして、前記側ロープ１と前記側張５のうち長手方向両外側 の側張５ａ、５ｂ（一方のみ図示）に囲まれた部分に、幅１０ｍ、長さ２００ｍ 程度の長尺の消波シート６をその要部を前記側張に繋止させながら海上に設置し ていた。この消波シート６は厚地のキャンパス地によって製せられている。In this wave-dissipating sheet, first, two side ropes 1 and 1 are installed in parallel in a direction orthogonal to a wave. A connecting rope 4 having an anchor 3 at the other end is connected to the end of the side rope 1 where the float 2 is provided, and the anchor 3 is dropped on the seabed. Further, side stretches 5, 5, ... For connecting the outer peripheral main part of the wave-dissipating sheet are arranged so as to intersect with the side ropes 1. A connecting rope 4 provided with an anchor 3 at the other end is connected to the end of each of these lateral lines 5, and the anchor 3 is dropped on the seabed. Further, a float 2 is provided at a portion where the side stretch 5 and the side rope 1 intersect. Then, a long wave-dissipating sheet 6 having a width of 10 m and a length of 200 m is surrounded by the side ropes 5a and 5b (only one is shown) on both sides in the longitudinal direction of the side rope 1 and the side stretcher 5. Was installed on the sea with its main part tied to the side wall. This wave-dissipating sheet 6 is made of thick campus ground.
【０００４】 このようにして設置される消波シート６は、不必要となったときには装置を回 収することができるため、景観保護にも役立ち、また、生簀などの海上の特定な 部分に対する消波が手軽に行えた。The wave-dissipating sheet 6 installed in this way is useful for landscape protection because it can recover the device when it is no longer needed, and it can also be used to protect specific parts of the sea such as cages. The waves were easy.
【０００５】[0005]
【考案が解決しようとする課題】 しかし、長尺の消波シート６は装置回収時に、なにかの拍子に消波シート６か ら手を離してしまうと、消波シート６は水中に沈んでしまうため、常に船上や空 中で保持している必要があり、そしてその重さはかなりのものであり、大変手間 取っていた。また、部分補修の必要があっても補修作業がしにくく、消波シート ６全体の交換は費用の面でも問題があった。さらに、長尺の消波シート６は消波 の際の抵抗が部分的にとどまらず、大きい範囲に影響を及ぼしてしまうため、こ れを保持するためには消波シート６自体の素材やその他の部品、取り付け部分等 の強化を大にすることが必要であった。However, if the long wave-dissipating sheet 6 is removed from the wave-dissipating sheet 6 when the device is recovered, the wave-dissipating sheet 6 will be submerged in water. Therefore, it was necessary to always hold it on board or in the air, and its weight was considerable, which was very time-consuming. Further, even if partial repair is required, it is difficult to carry out the repair work, and replacement of the entire wave-eliminating sheet 6 has a problem in terms of cost. Furthermore, the long wave-dissipating sheet 6 has a partial resistance to the wave-dissipating effect, which affects a large area. It was necessary to greatly strengthen the parts, mounting parts, etc.
【０００６】 本考案はこれらの点に鑑みてなされたものであり、消波シートの取り付け、取 り外し作業が容易にでき、また、消波シートの交換もローコストで行なうことが できる消波装置を提供することを目的とする。The present invention has been made in view of the above points, and a wave-dissipating device capable of easily attaching and detaching the wave-disintegrating sheet and replacing the wave-disintegrating sheet at low cost. The purpose is to provide.
【０００７】[0007]
前記目的を達成するために、本考案の消波装置は消波装置を固定させる側ロー プを複数本配置し、前記側ロープに交差するように複数本の側張を所定間隔で配 置し、前記側ロープ間に補助部材を展張し、前記補助部材の上面に分割したシー ト状の消波部材を展張することを特徴とする。 In order to achieve the above-mentioned object, the wave breaker of the present invention has a plurality of side ropes for fixing the wave breaker, and a plurality of side tensioners arranged at predetermined intervals so as to intersect the side ropes. An auxiliary member is stretched between the side ropes, and a sheet-shaped wave-dissipating member divided on the upper surface of the auxiliary member is stretched.
【０００８】[0008]
本考案の消波装置によれば、補助部材を展張し、消波部材を分割して小片とし たことにより、消波シートの取り付け、取り外し作業が容易になる。また、小片 の消波部材は、波から受ける抵抗を部分的に限ることができるため、影響が全体 に及ばず、そのために各消波部材の耐久も伸び、さらに交換部品の形状が小さく なるのでコストも抑えることができる。さらにまた、消波部材の１枚ずつを小片 に形成したことで消波部材自体の製作が容易になる。 According to the wave breaking device of the present invention, the auxiliary member is expanded and the wave breaking member is divided into small pieces, so that the work of attaching and removing the wave breaking sheet is facilitated. In addition, since the small wave-breaking member can partially limit the resistance received from the wave, it does not have an overall effect, which increases the durability of each wave-breaking member and reduces the shape of the replacement part. The cost can also be reduced. Furthermore, by forming each of the wave breaking members into small pieces, the wave breaking member itself can be easily manufactured.
【０００９】[0009]
以下、本考案の実施例を図１から図３について説明する。なお、従来例と同一 部分には同一符号を付して説明する。 An embodiment of the present invention will be described below with reference to FIGS. The same parts as those of the conventional example will be described with the same reference numerals.
【００１０】 本実施例は、図１に示すように、幅１０ｍで２００ｍ強の長さを有する消波装 置を例にとって説明する。This embodiment will be described by taking an example of a wave canceling device having a width of 10 m and a length of slightly more than 200 m as shown in FIG.
【００１１】 まず、波に直交する方向に２本の側ロープ１、１を平行に設置する。この側ロ ープ１の浮き２が設けられた端部には、他端部にアンカー３を設けた連結ロープ ４が繋止されており、前記アンカー３は海底に投下されている。また、前記側ロ ープ１と交差するようにして、後述する消波部材の外周要部を繋止するための側 張５、５…を一定間隔で配置する。この間隔は、後述するシート状の消波部材の 長さとほぼ等しいものとなる。また、これらの側張５はその端部には、他端部に アンカー３を設けた連結ロープ４が繋止されており、前記アンカー３は海底に投 下されている。また、この側張５と前記側ロープ１とが交差する部分には浮き２ が設けられている。そして、前記側ロープ１と前記側張５のうち両外側の側張５ ａ、５ｂに囲まれた部分に、幅１０ｍ、長さ２００ｍ程度の長尺の網状の補助部 材７をその要部を前記側張５に図示しない繋止部材を用いて繋止させながら海上 に展張する。つぎに各側張５間に、幅１０ｍ、長さは消波装置の長手方向寸法を 前記側張間数で分割した長さであるシート状の消波部材８を図示しない繋止部材 を用いて展張する。なお、前記消波部材８の大きさ特に装置の長手方向の長さは 、前記実施例より小さくしたり、大きくする等、必要に応じて変更するようにす るとよい。また、前記側張５を１１本使用した場合、シート状の消波部材８は長 さが１０ｍのほぼ正方形となり、消波装置には１０枚が展張されることになる。 なお、前記消波部材８はキャンバス地等によって製作されている。First, the two side ropes 1 and 1 are installed in parallel in the direction orthogonal to the wave. A connecting rope 4 having an anchor 3 at the other end is connected to the end of the side rope 1 where the float 2 is provided, and the anchor 3 is dropped on the seabed. Further, side walls 5, 5, ... For connecting the outer peripheral main part of the wave-dissipating member, which will be described later, are arranged at regular intervals so as to intersect with the side ropes 1. This interval is approximately equal to the length of the sheet-shaped wave-dissipating member described later. A connecting rope 4 provided with an anchor 3 at the other end is connected to the end of each of the lateral lines 5, and the anchor 3 is dropped on the seabed. Further, a float 2 is provided at a portion where the side stretch 5 and the side rope 1 intersect. Then, a long net-like auxiliary member 7 having a width of about 10 m and a length of about 200 m is provided at a portion of the side rope 1 and the side stretch 5 surrounded by the outer side stretches 5a and 5b. Is stretched on the sea while being locked to the lateral side 5 by using a locking member (not shown). Next, a sheet-shaped wave-breaking member 8 having a width of 10 m and a length of a length obtained by dividing the lengthwise dimension of the wave-breaking device by the number of the side-hanging members is used between the side stretchers 5 by using a locking member (not shown). And expand. The size of the wave breaking member 8, particularly the length in the longitudinal direction of the device, may be changed as needed, such as by making it smaller or larger than that in the above embodiment. Further, when 11 of the side stretchers 5 are used, the sheet-shaped wave-dissipating member 8 has a substantially square shape with a length of 10 m, and 10 sheets are spread on the wave-dissipating device. The wave breaking member 8 is made of canvas or the like.
【００１２】 また、第２実施例として、前述した第１実施例に用いた幅１０ｍ、長さ２００ ｍ程度の長尺の網状の補助部材７を、同じ第１実施例で用いた消波部材８のよう に、その長さを消波装置の長手方向寸法を側張間数で分割した長さに形成し、図 示しない繋止部材を用いて各側張間に展張することもできる。Further, as a second embodiment, the wave-eliminating member using the long net-like auxiliary member 7 having a width of 10 m and a length of about 200 m used in the first embodiment described above in the same first embodiment. As shown in FIG. 8, it is also possible to form the length into a length obtained by dividing the longitudinal dimension of the wave-breaking device by the number of lateral tensions, and extend it between the lateral tensions by using a locking member (not shown).
【００１３】 このように、消波部材８の長さを例えば１０ｍのように一定にするならば、消 波装置の長さは、消波部材８の使用枚数に応じて変えることができる。また、こ の一連の作業工程は海上ですべて行われる必要はない。たとえば、網状の補助部 材７を展張するまでの作業工程を陸地にて行い、海上ではそれ以降の作業工程の みを行う等、消波装置の部材の重量や嵩、作業性等を考慮して作業を分割しても よい。As described above, if the length of the wave breaking member 8 is constant, for example, 10 m, the length of the wave breaking device can be changed according to the number of used wave breaking members 8. Also, this series of working steps does not have to be carried out at sea. For example, the work steps until the net-shaped auxiliary member 7 is stretched are performed on land, and only the work steps thereafter are performed on the sea. You may divide the work.
【００１４】 つぎに、本考案の作用について説明する。Next, the operation of the present invention will be described.
【００１５】 本実施例においては、消波部材８の下面に網状の補助部材７が配置され、さら に、消波部材８の長さを側張間の寸法とほぼ等しくして消波部材８を形成したこ とにより、簡単な海上での展張作業によって、消波の効果をあげることができる 。In this embodiment, a net-shaped auxiliary member 7 is arranged on the lower surface of the wave breaking member 8, and further, the length of the wave breaking member 8 is made substantially equal to the dimension of the side stretcher, and the wave breaking member 8 is formed. By forming the seams, the wave-dissipating effect can be enhanced by a simple sea spreading operation.
【００１６】 すなわち、本考案の消波装置は波９と直交する位置の海面１０に設置される。 消波装置はアンカー３によって設置位置に繋留され、展張された消波部材８は連 結ロープ４の長さが許す範囲で海面１０に浮遊する。つまり、海面１０の高さが 低い場合、図２に示すように、消波部材８は連結ロープ４の長さをあまらせて、 生じた連結ロープ４の遊び分だけ海面１０を左右に漂い（図中ｘ、ｙ）、海面１ ０が高い場合、消波部材８は連結ロープ４を完全に張った状態でほとんど一定位 置の海面１０に浮く。That is, the wave breaking device of the present invention is installed on the sea surface 10 at a position orthogonal to the wave 9. The wave breaking device is anchored at the installation position by the anchor 3, and the expanded wave breaking member 8 floats on the sea surface 10 within the range permitted by the length of the connecting rope 4. That is, when the height of the sea surface 10 is low, as shown in FIG. 2, the wave breaking member 8 increases the length of the connecting rope 4 so that the sea surface 10 drifts left and right by the amount of play of the connecting rope 4 that has occurred. When the sea surface 10 is high (x, y in the figure), the wave breaking member 8 floats on the sea surface 10 at a substantially fixed position with the connecting rope 4 being completely stretched.
【００１７】 そして、図３に示すように、沖から寄せる波９は、海面１０に浮かぶ消波部材 ８を通過する際に、連結ロープ４の長さの許容範囲内で海面１０に漂う消波部材 ８によって行く手を阻まれ、消波部材８通過後の波高を制限され、岸側に寄せる ことになる。Then, as shown in FIG. 3, when the wave 9 coming from the offshore passes through the wave canceling member 8 floating on the sea surface 10, the wave canceling drifts on the sea surface 10 within the allowable range of the length of the connecting rope 4. The member 8 will block the path, and the wave height after passing the wave-eliminating member 8 will be restricted, and the member will move to the shore.
【００１８】 下表は実験による消波の効果の概要を示す表である。The following table is a table showing an outline of the effect of wave-dissipation by experiments.
【００１９】 この表は、５０ｍ、１００ｍ、１５０ｍの波長の３種類の波９の、それぞれ入 射波高２ｍ、４ｍ、６ｍの場合の消波効果を実験したものである。[0019] This table is an experiment on the wave-eliminating effect of three types of waves 9 having wavelengths of 50 m, 100 m, and 150 m when the incident wave heights are 2 m, 4 m, and 6 m, respectively.
【００２０】 この表から、前記９種類のいずれの波９も消波部材８を通過した後には平均し て３０％程、波高を低くさせられていることが分かる。From this table, it can be seen that the wave height of each of the nine types of waves 9 is lowered by about 30% after passing through the wave-eliminating member 8.
【００２１】 このような消波効果を期待できる本考案の消波装置は、消波部材を消波装置の 長手方向寸法を側張間数で分割した長さに形成したので、その取り付け、取り外 し作業が容易になる。また、全長２００ｍにわたって設置された消波装置は、打 ち寄せる波の抵抗が部分によって異なるため、その耐用も異なってくるが、消波 部材は小型化されたため、部材交換のコストも押さえられ、しかも、消波部材そ のものの製作も容易になる。In the wave breaking device of the present invention which can expect such a wave breaking effect, since the wave breaking member is formed to have a length in the longitudinal direction of the wave breaking device divided by the number of side stretches, the mounting and mounting thereof can be performed. Easy removal work. In addition, the wave-eliminating device installed over a total length of 200 m has different durability because the resistance of the wave to be struck differs depending on the part, but since the wave-eliminating member has been downsized, the cost of replacing the member can be suppressed, Moreover, it becomes easy to manufacture the wave breaking member itself.
【００２２】 なお、本考案は前記実施例に限定されるものではなく、必要に応じて変更する ことができる。It should be noted that the present invention is not limited to the above-mentioned embodiment, but can be modified as necessary.
【００２３】[0023]
このように本考案の消波装置は構成され作用するものであるから、消波部材の 取り付け、取り外し作業が容易になる。また、小型化された消波部材は、波の抵 抗が消波装置全体に及ばないので各消波部材の耐久も伸び、さらに交換部品の形 状が小さくなるのでコストも抑えることができる。さらにまた、消波部材自体の 製作が容易になるなどの効果を奏する。 As described above, since the wave-breaking device of the present invention is constructed and operates, the work of attaching and removing the wave-breaking member becomes easy. Further, since the wave resistance of the downsized wave breaking member does not extend to the whole wave breaking device, the durability of each wave breaking member is extended, and the shape of the replacement part becomes smaller, so that the cost can be suppressed. Furthermore, there is an effect that the wave-absorbing member itself can be easily manufactured.
