本発明は、氷海域５こ面した海岸等で海産物の養殖等を
行う５こ際し、養殖場等の必要海域に流氷が侵入しない
ようにした防水堤に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproof embankment that prevents drift ice from entering the necessary sea areas such as aquaculture farms when cultivating marine products, etc. on coasts facing frozen areas. be.
氷海域に面した海岸で、コンブやホタテ等の養殖を行な
う際、これらの養殖場に流氷が侵入すると、養殖施設が
大きな扱害を被るので、この扱害を防止するための対策
が必要である。When cultivating kelp, scallops, etc. on coasts facing frozen waters, if drift ice invades these farms, the aquaculture facilities will suffer major damage, so measures are needed to prevent this damage. be.
しかし、この対策を施すに当たっては、単なるコンクリ
ートブロック等で養殖場を囲むと、流氷の移動力によっ
て、コンクリートブロック等の位置がずれたり、あるい
は、破損する危険があることと、海流、潮流等の環境が
変わるので、養殖物に悪影響を及ぼす等の問題がある。However, when implementing this measure, it is important to note that if the farm is surrounded by simple concrete blocks, etc., there is a risk that the concrete blocks will be displaced or damaged due to the moving force of the drift ice, and that there is a risk of the concrete blocks being damaged due to ocean currents, tides, etc. Since the environment changes, there are problems such as adverse effects on aquaculture products.
そこで、本発明は、これらの問題を解決するためｔこ成
されたものであって、傾斜面により流氷を簡単に破砕す
ることによって、流氷の養殖場等への侵入を防止すると
さもに、海流や潮流等の環境が変化せず、しかも、消波
効果も期待できる防水堤を提供することを目的とする。Therefore, the present invention has been made to solve these problems, and by easily crushing drift ice with an inclined surface, it is possible to prevent drift ice from entering into aquaculture farms, etc. The purpose of the present invention is to provide a waterproof embankment that does not change the environment such as waves and tidal currents, and can also be expected to have a wave-dissipating effect.

てなる防水堤を要旨とするものである。For this reason, the present invention forms a drift ice prevention body having a fence-like slope surface by removably arranging a large number of drift ice prevention beams in a fence shape within a tilt girder frame, and Struts are extended from both ends, and the struts and the ice prevention body form a substantially triangular shape when viewed from the side, and the tips of one strut and the other strut are connected by a placer, Further, a triangular pusher having a triangular shape when viewed from the front is arranged at the lower part of the drift ice preventer, and these struts and the triangular pusher are brought to the bottom of the water to position a part of the inclined surface of the drift ice preventer at the water surface F. The main purpose of this project is to create a waterproof embankment.
次に図面により本発明の一実施例を説明する。Next, one embodiment of the present invention will be described with reference to the drawings.
図１：こおいて、防水堤１は、スチールあるいは鉄筋コ
ンクリート等により側面視概略三角形状に形成されてお
り、その上面には、流氷群に向かう流氷防止体２が、傾
斜ガーダ−枠３内に柵状に流氷防止梁４を多数着脱自在
に配列することにより形成されている。Figure 1: The waterproof embankment 1 is made of steel or reinforced concrete and has a roughly triangular shape when viewed from the side, and on its upper surface, a drift ice prevention body 2 facing the drift ice group is installed inside the inclined girder frame 3. It is formed by arranging a large number of drift ice prevention beams 4 in a fence shape in a detachable manner.
このように形成した流氷防止体２は、傾斜して配置され
ており、その水面に対する傾斜角が、好ましくは、約３
０°から６０°の間になるように配置されている。The drift ice preventer 2 formed in this way is arranged at an angle, and the angle of inclination with respect to the water surface is preferably about 3.
The angle is between 0° and 60°.
また、前記流氷防止体２の傾斜ガーダ−枠３の一端部か
らは脚体の一部であるストラット５が延長され、このス
トラット５は、傾斜ガーダ−枠３の他端部から延長され
たプレース６により連結されている。Further, a strut 5, which is a part of the leg body, is extended from one end of the inclined girder frame 3 of the drift ice prevention body 2, and this strut 5 is connected to a place extended from the other end of the inclined girder frame 3. 6.
このストラット５及びプレース６からなる脚体は、流氷
防止体２の長手方向両端部にそれぞれ位置している。The legs consisting of the struts 5 and places 6 are located at both longitudinal ends of the drift ice prevention body 2, respectively.
更に１、流氷防止体２の傾斜ガーダ−枠３の他端部から
は、正面視三角形状の三角形押７が延長されている。Furthermore, a triangular pusher 7 having a triangular shape in front view extends from the other end of the inclined girder frame 3 of the drift ice prevention body 2.
したがって、流氷防止体２は、２個のストラット５及び
プレース６と、１個の三角形押７の三本の脚で支持され
ることになる。Therefore, the drift ice prevention body 2 is supported by three legs: two struts 5 and places 6, and one triangular pusher 7.
これらの脚体の長さは、前述したように、流氷防止体２
の傾斜角が適正角度になる長さに定められるとともに、
この流氷防止体２が水面８の上方に傾斜面の上部を位置
させ、水面８の下方に傾斜面の下部を位置させた時に脚
体が着底するように成されている。As mentioned above, the length of these legs is determined by the length of the drift ice prevention body 2.
The length is set so that the inclination angle of
The drift ice prevention body 2 is configured such that the upper part of the slope is located above the water surface 8, and the legs reach the bottom when the lower part of the slope is located below the water surface 8.
このように構成した防水堤１を例えば、第１図に示すよ
うに、必要数だけ配列する。For example, as shown in FIG. 1, the required number of waterproof embankments 1 constructed in this manner are arranged.
いま、このように配列した防水堤１に流氷が押し寄せて
来た場合には、第２図に示すように、矢印へ方向へ移動
する流氷９が、流氷防止体２の流氷防止梁４あるいは、
傾斜ガーダ−枠３へ乗り上げることによってこの流氷９
を、折り曲げて細かく破砕する。Now, when drift ice is rushing onto the waterproof embankment 1 arranged in this way, as shown in FIG.
This drift ice 9 is removed by running onto the inclined girder frame 3.
Fold and crush into small pieces.
砕かれた流氷片９ａは、他の流氷に重合したり、あるい
はバラバラになるので、破砕後の流氷片９ａによる防水
堤１への流氷力は殆んど無に等しくなる。Since the crushed pieces of ice 9a polymerize with other pieces of ice or break apart, the ice force exerted on the waterproof embankment 1 by the pieces of crushed ice 9a becomes almost nil.
したがって、防水堤１へ加わる流氷力は、流氷９を砕く
際に加わるわずかな力のみとなるので、防水堤１の位置
がずれたり、破壊したりすることがなく、結局、流氷９
を安全に防水堤１により止めることができる。Therefore, the drift ice force applied to the waterproof embankment 1 is only a small force applied when breaking the drift ice 9, so the waterproof embankment 1 is not displaced or destroyed, and in the end, the drift ice 9
can be safely stopped by the waterproof embankment 1.
また、防水堤１の流氷防止体２は、柵状に形成されてい
るので、防水堤１を海水が自由シこ通過でき、海流や潮
流を防げることがない。Further, since the drift ice prevention body 2 of the waterproof embankment 1 is formed in the shape of a fence, seawater can freely pass through the waterproof embankment 1, and ocean currents and tides are not blocked.
更に流氷防止体２の形状、寸法、材料等を適宜定めるこ
とにより、消波効果も期待でき、また、防氷堤１のｌフ
宅ツクの重量を示さくすることもできる。Furthermore, by appropriately determining the shape, size, material, etc. of the drift ice preventer 2, a wave-dissipating effect can be expected, and the weight of the ice barrier 1 can also be reduced.
したかって、防水堤１の交換が簡単であるとともに、コ
ストを安くすることもできる。Therefore, the waterproof embankment 1 can be easily replaced and the cost can be reduced.
また、傾斜ガーダ−枠３内１１こ柵状に流氷防止梁４を
着脱自在に配列したためｔこ、必要に応じて流氷防止梁
４の交換を容易に行うことができるから、保守管理上有
利である。In addition, since the drift ice prevention beams 4 are removably arranged in the shape of 11 fences inside the inclined girder frame 3, the drift ice prevention beams 4 can be easily replaced as needed, which is advantageous in terms of maintenance management. be.
さらに、ストラット５と三角形押７からなる三本の足で
水底に着底せしめるため、着底に際しては三本の足だけ
についてそれぞれの脚の長さを勘案すればよく、これに
よって海底形状に左右されずに安全かつ簡単に防水堤の
設装置が可能となる。Furthermore, since the three legs consisting of the struts 5 and the triangular pushers 7 are used to touch the bottom of the water, it is only necessary to consider the length of each of the three legs when landing on the bottom. This makes it possible to safely and easily install a waterproof embankment without having to worry about it.
したがって、海底面が平坦でなく、特に、氷のため海底
面が削られて硬い岩盤が現れている場合が多い氷海域で
の防水堤の設置が盲利となる。Therefore, the installation of waterproof embankments becomes a blind advantage in icy areas where the seabed is not flat, and especially in icy areas where the seabed has been scraped by ice and hard rock is often exposed.
更に、水深に応じて防水堤１を自由に設計できるばかり
か、流氷力を極めて軽減できるので、耐久性に富む利点
もある。Furthermore, not only can the waterproof embankment 1 be designed freely according to the water depth, but also the force of drifting ice can be significantly reduced, which has the advantage of being highly durable.
一方、第３図、第４図に示すように、三角形押７ａを傾
斜ガーダ−枠３と同一平面になるように配置すれば、三
角形押７ａと傾斜ガーダ−枠３及び流氷防止梁４を１体
的に成形（コンクリート打設等）することができる。On the other hand, as shown in FIGS. 3 and 4, if the triangular pusher 7a is arranged on the same plane as the inclined girder frame 3, the triangular pusher 7a, the inclined girder frame 3, and the drift ice prevention beam 4 can be placed in one place. It can be physically formed (concrete placement, etc.).
更に、第３図、第４図ｔこ示すように、ストラット５ａ
やプレース６ａを鋼製にすることもでき、このようにす
れば、コンクリート等の使用量を少なくすることができ
る等幾多の利点を有し、その作用効果は太きい。Furthermore, as shown in FIGS. 3 and 4, the struts 5a
The place 6a can also be made of steel, and this has many advantages such as being able to reduce the amount of concrete used, and its effects are significant.
