Description

本発明は、防潮施設に関するものである。   The present invention relates to a tide prevention facility.

高潮は、台風や発達した低気圧などによって潮位が異常に上昇する現象をいう。
海面が異常に上昇する原因は、強い風が海水を海岸に吹き寄せて海面を上昇させ、低気圧によって海水を吸い上げることから生じる。
そのような現象が満潮時に重なるとさらに海面が上昇して、海や川に接近している民家などはきわめて危険な状態となる。
そのような危険を避けるために、従来から多数の防潮堤が開発されているが、実施には費用や技術上の制約から刑務所の壁のような擁壁を作ってエネルギーを跳ね返すような構想が一般的である。
特開平7−113219
High tide is a phenomenon in which the tide level rises abnormally due to typhoons and developed low pressure.
The reason why the sea level rises abnormally is that a strong wind blows seawater to the coast to raise the sea level and sucks up seawater by low pressure.
When such a phenomenon overlaps at high tide, the sea level rises further, and private houses close to the sea and rivers become extremely dangerous.
In order to avoid such a risk, many seawalls have been developed in the past, but due to cost and technical constraints, implementation of a concept to rebound energy by creating a retaining wall like a prison wall. It is common.
JP-A-7-113219

上記したような従来の防潮施設には次のような問題がある。
<1> 家屋の屋根よりも高い、刑務所の壁のような巨大な防潮堤を長距離にわたって構築すると、海岸線や河川に沿って長大な目隠しを設置したことになるから、水域と住民との生活が完全に切断されてしまい、水辺と人々がなじむことによって形成される水辺の文化が育たない。
<2> あるいは巨大なエアバッグを膨らませて止水する防潮堤の提案もあるが、特殊で高価な繊維を使用するものであるため、長い延長にわたって設置することは経済的に困難である。
<3> また膨張させたエアバッグは、その両端を支柱で支持する必要があるが、その支柱にすべての力がかかるために、大きな構造物を設置しなければならない。
<4> その他の防潮施設でも、すべて高潮のエネルギーを全面的に受け止める構造であるから、きわめて大きな支持力が必要となり、不経済なものであった。
The conventional tide facilities as described above have the following problems.
<1> If a huge seawall like a prison wall, which is higher than the roof of a house, is constructed over a long distance, a large blindfold is installed along the coastline and river, so the life of the water area and residents Is completely cut off, and the culture of the waterside formed by the waterfront and people's familiarity does not grow.
<2> Alternatively, there is a proposal of a seawall that inflates a huge airbag to stop water, but it is economically difficult to install over a long extension because it uses special and expensive fibers.
<3> Moreover, although it is necessary to support the both ends with the support | pillar at the inflated airbag, since all force is applied to the support | pillar, you have to install a big structure.
<4> All other tide protection facilities have a structure that fully receives the energy of storm surges, so they require extremely large support and are uneconomical.

上記のような課題を解決するために本発明の防潮施設は、高潮などによる災害を防止するための施設であって、陸上に設置した支柱と、支柱に支点を介して回転自在に取り付けた屋根兼止水面体と、支柱の支点を中心に屋根兼止水面体を回転させる回転力付与装置とで構成し、屋根兼止水面体を、支点を中心に回転させて高潮の来る方向に向けて設置し得るように構成した防潮施設である。
また本発明の防潮施設は、高潮などによる災害を防止するための施設であって、陸上に設置した陸側支柱と、陸側支柱よりも海側に設置した海側支柱と、陸側支柱に支点を介して回転自在に取り付けた屋根兼止水面体と、海側支柱に支点を介して回転自在に取り付けた屋根兼エネルギー吸収面体と、支柱の支点を中心に屋根兼止水面体、あるいは屋根兼エネルギー吸収面体を回転させる回転力付与装置とで構成し、屋根兼止水面体を、陸側支柱の支点を中心に回転させて高潮の来る方向に向けて設置し得るように、かつ、屋根兼エネルギー吸収面体を、海側支柱の支点を中心に回転させて高潮の来る方向に向けて設置し得るように構成した、防潮施設である。
また、本発明の防潮施設は、屋根兼止水面体は、支点の一方を屋根兼止水面体として構成し、支点の他方に重量体を設け、支点の他方の重量体の重量を除去することによって、支点の一方の屋根兼止水面体が支点を中心に回転するように構成した防潮施設である。

以下図面を参照にしながら本発明の好適な実施の形態を詳細に説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

<1>本発明の対象。
本件発明の対象は「高潮など」により発生する災害を防止するための施設である。
すなわち、台風による高潮に限らず、小規模な地震にともなう小規模な津波、豪雨による水位の上昇による堤防からの越水、あるいは地球規模の異常気象に伴う潮位、河川の水位の上昇などを対象とすることができる。
したがって本件明細書や請求項では「海側」とか「海側支柱」のように記載するが、これは河川の堤防においては「川側」とか「流水側に立てる柱」のような意味である。
<1> Subject of the present invention.
The subject of the present invention is a facility for preventing disasters caused by “storm surges”.
In other words, not only storm surges caused by typhoons, but also small tsunamis caused by small earthquakes, flooding from embankments caused by rising water levels due to heavy rains, tide levels due to global abnormal weather, rising river levels, etc. It can be.
Therefore, in the present description and claims, it is described as “sea side” or “sea side support”, but this means “river side” or “pillar standing on the running water side” in river dikes. .

<2>基本的な構成。
本発明の防潮施設は、基本的には支柱1と屋根と、屋根を回転させる回転力付与装置とによって構成する。
屋根としては、止水性を維持した屋根兼止水面体2と、通水性が維持されている屋根兼エネルギー吸収面体3とを採用することができる。
回転力付与装置としては、外から回転力を与える構成と、釣合い重りの重量を減少させる構成を採用することができる。
<2> Basic configuration.
The tide facility of the present invention is basically constituted by the support column 1, the roof, and a rotational force applying device that rotates the roof.
As the roof, it is possible to employ a roof / water-stopping surface body 2 that maintains water-stopping properties and a roof / water-absorbing surface body 3 that maintains water permeability.
As the rotational force applying device, it is possible to adopt a configuration in which a rotational force is applied from the outside and a configuration in which the weight of the counterweight is reduced.

<3>屋根兼止水面体2。
高潮、津波の発生する可能性の高い海岸に、海岸線に沿って多数本の支柱1を設置する。
そしてこの陸上に設置した支柱1に、屋根兼止水面体2を取り付ける。
屋根兼止水面体2とは、貫通孔の存在しない無孔体で構成した面体のことである。
たとえば、周囲を枠で囲い、その内部に不透水性のシートや鋼製、合成樹脂製、木製の板を取り付けた構成を採用することができる。
なお、この明細書で「面体」とは、柔軟性に富んだ膜体や、柔軟性に乏しい剛体の面をも含む意味で使用している。
屋根兼止水面体2を海側へ向けて傾斜させ、その先端を地表面に接触させて陸上側への止水を図るが、完全な止水機能を維持することが必要である。
そのために屋根兼止水面体2の先端の設置線にゴム袋などのパッキン材を取り付けて水密性を図ることができる。
<3> Roof and water stop surface body 2.
Many struts 1 are installed along the coastline on the coast where storm surge and tsunami are likely to occur.
And the roof and water stop surface body 2 is attached to the support | pillar 1 installed on the land.
The roof and water stop surface body 2 is a surface body constituted by a non-porous body having no through hole.
For example, it is possible to adopt a configuration in which the periphery is surrounded by a frame and an impermeable sheet, steel, synthetic resin, or wooden plate is attached to the inside.
In this specification, the “face body” is used to include a film body having a high flexibility and a rigid surface having a low flexibility.
The roof / waterstop body 2 is inclined toward the sea side, and its tip is brought into contact with the ground surface to stop water on the land side. However, it is necessary to maintain a complete waterstop function.
Therefore, a water tightness can be achieved by attaching a packing material such as a rubber bag to the installation line at the tip of the roof / waterproof surface body 2.

<4>支柱1との取り付け。
屋根兼止水面体2は、支柱1に設けた支点11を介して回転自在に取り付ける。
図の実施例では、支点11を支柱1の頭部に設けてあるが、その位置に限定されるものではない。
屋根兼止水面体2は支点11を中心に回転自在であるから、通常は屋根兼止水面体2を水平に位置させておき、日除けや雨除けとして機能させることができる。
非常時には支点11を中心に回転させて高潮の来る方向に向けた面体として機能させることができる。
<4> Attachment with the support 1.
The roof / waterstop body 2 is rotatably attached via a fulcrum 11 provided on the support column 1.
In the illustrated embodiment, the fulcrum 11 is provided on the head of the support column 1, but the position is not limited thereto.
Since the roof / waterstop body 2 is rotatable around the fulcrum 11, the roof / waterstop body 2 can be normally positioned horizontally to function as an awning or rain shield.
In an emergency, it can be rotated around the fulcrum 11 so as to function as a face body directed in the direction of the storm surge.

<5>エネルギー吸収面体の設置。
屋根兼止水面体2とは別に、屋根兼エネルギー吸収面体3を設置する構成について説明する。(図4、5、6)
まず、支柱1は、陸側支柱1Aと海側支柱1Bとを海岸線にそってほぼ平行に2列に設置する。
陸側支柱1Aとは陸側に設置した支柱である。
海側支柱1Bとは陸側支柱1Aよりも海側に設置した支柱である。
そして陸側支柱1Aには前記した屋根兼止水面体2を、支点11を介して回転自在に取り付ける。
この陸側支柱1Aの位置において、高潮などの陸側への流入を阻止する。
一方、海側支柱1Bには支点11を介して回転自在に屋根兼エネルギー吸収面体3を取り付ける。
この海側支柱1Bの位置において、高潮などのエネルギーを吸収する。
<5> Installation of energy absorbing face pieces.
The structure which installs the roof and energy absorption surface body 3 separately from the roof and water stop surface body 2 is demonstrated. (Fig. 4, 5, 6)
First, the struts 1 are installed in two rows, substantially parallel to the coastline, with land-side struts 1A and sea-side struts 1B.
The land side support 1A is a support installed on the land side.
Sea side support 1B is a support installed in the sea side rather than land side support 1A.
And the above-mentioned roof and still water surface body 2 is attached to the land-side column 1A via a fulcrum 11 so as to be rotatable.
At the position of the land-side strut 1A, an inflow to the land side such as a storm surge is prevented.
On the other hand, the roof-and-energy-absorbing face body 3 is attached to the sea-side column 1B via a fulcrum 11 so as to be rotatable.
Energy such as a storm surge is absorbed at the position of the sea side support 1B.

<6>屋根兼エネルギー吸収面体3の構造。
屋根兼エネルギー吸収面体3とは、分散した貫通孔を開設した有孔体で構成した面体のことである。
たとえば、周囲を枠で囲い、その内部に網や穴あきのシート、穴あきの鋼板、厚さの厚い不織布マット、などのエネルギー吸収材料を取り付けた構成を採用することができる。
枠体は窓枠のような剛直な鋼材で構成するだけでなく、ガレージや商店の巻き取り式のシャッターのように折り曲げて巻き取ったり、曲面を通過させ得る構成を採用できる。
エネルギー吸収材料としては、前記のような合成樹脂製の網や打ち抜き鋼板、不織布のマット以外に、合成樹脂の板やコンクリートの板に穴を開けた有孔体、擁壁の裏に敷設するドレーン材や地盤改良の排水材に使用されているような合成樹脂繊維の厚いマットやシート、あるいはそれらの複合体などを利用できる。
エネルギー吸収材料としては、水が通過する際に一定の時間を要し、抵抗を受けるような材料が好ましく、多数の貫通孔や連続孔、細孔の周囲や絡まった繊維が水の通過の抵抗となりエネルギーを吸収することになる。
とくに繊維を絡ませて形成した面体を使用すれば、繊維の隙間を透過する際に、高潮などの衝撃のエネルギーは大きく吸収されて位置のエネルギーに変換される。
同時に屋根兼エネルギー吸収面体3の全体がたわむことによっても衝撃のエネルギーの吸収に貢献する。
ここでエネルギーの吸収とは、衝撃力の吸収、波力の減衰などのことを意味する。
<6> The structure of the roof and energy absorbing face 3.
The roof and energy absorbing face piece 3 is a face piece formed of a perforated body having dispersed through holes.
For example, it is possible to adopt a configuration in which the periphery is surrounded by a frame and an energy absorbing material such as a net, a perforated sheet, a perforated steel plate, a thick nonwoven fabric mat, or the like is attached to the inside.
The frame body is not only made of a rigid steel material such as a window frame, but can also be constructed such that it can be folded and wound or passed through a curved surface, like a garage or a retractable shutter of a store.
In addition to the synthetic resin nets, punched steel sheets, and non-woven mats, the energy absorbing material includes a perforated body with holes in the synthetic resin plate and concrete plate, and a drain laid on the back of the retaining wall. A thick mat or sheet of synthetic resin fibers, or a composite thereof, which is used as a drainage material for materials and ground improvement, can be used.
The energy absorbing material is preferably a material that requires a certain amount of time for water to pass through and is subject to resistance. Many through-holes, continuous holes, and surrounding fibers and entangled fibers are resistant to water passage. And will absorb energy.
In particular, if a face piece formed by entangled fibers is used, the energy of impact such as storm surge is greatly absorbed and converted into position energy when passing through the gaps of the fibers.
At the same time, the entire roof-and-energy-absorbing face 3 is bent, which contributes to the absorption of impact energy.
Here, energy absorption means absorption of impact force, attenuation of wave force, and the like.

<7>海側支柱1Bとの取り付け。
このような構成の屋根兼エネルギー吸収面体3を、海側支柱1Bの支点11に回転自在に取り付ける。
図の実施例では、支点11を支柱1の頭部に設けてあるが、その位置に限定されるものではない。
屋根兼エネルギー吸収面体3も支点11を中心に回転自在であるから、通常は屋根兼エネルギー吸収面体3を水平に位置させておき、日除けや雨除けとして機能させることができる。
非常時には支点11を中心に回転させて高潮の来る方向に向けたエネルギーを給する面体として機能させることができる。
<7> Attachment with the sea side support 1B.
The roof and energy absorbing face body 3 having such a structure is rotatably attached to the fulcrum 11 of the sea side support 1B.
In the illustrated embodiment, the fulcrum 11 is provided on the head of the support column 1, but the position is not limited thereto.
Since the roof and energy absorbing face 3 is also rotatable around the fulcrum 11, the roof and energy absorbing face 3 can be normally positioned horizontally to function as an awning or rain shield.
In an emergency, it can function as a face body that rotates around the fulcrum 11 to supply energy toward the direction of the storm surge.

<8>回転力付与装置4。
屋根兼止水面体2、あるいは屋根兼エネルギー吸収面体3に、支点11を中心とした回転を与えるために、回転力付与装置4が必要である。
そのために屋根兼止水面体2や屋根兼エネルギー吸収面体3の支点11を回転軸として、この回転軸にモーターで回転を与えたり、面体の一部に油圧ジャッキ、人力などによる推進力を与える。
この動力の付与によって、回転軸を中心に屋根兼止水面体2、屋根兼エネルギー吸収面体3を回転させて、水平姿勢、傾斜姿勢、あるいは鉛直の姿勢を維持させることができる。
支点11の回転軸を回転させるだけでなく、屋根兼止水面体2や屋根兼エネルギー吸収面体3の先端など、他の一部に引張力、押し出し力を与えて回転させることも可能である。
<8> A rotational force applying device 4.
In order to give the roof / water stop surface 2 or the roof / energy absorption surface 3 a rotation around the fulcrum 11, the rotational force applying device 4 is necessary.
For this purpose, the fulcrum 11 of the roof / waterstop surface 2 or the roof / energy absorbing surface 3 is used as a rotation axis, and the rotation shaft is rotated by a motor, or a propulsion force is applied to a part of the surface body by a hydraulic jack, human power, or the like.
By applying this power, the roof / waterstop surface 2 and the roof / energy absorption surface 3 can be rotated around the rotation axis to maintain a horizontal posture, an inclined posture, or a vertical posture.
In addition to rotating the rotation axis of the fulcrum 11, it is possible to rotate it by applying a tensile force or an extruding force to other parts such as the tip of the roof / waterstop surface 2 or the roof / energy absorption surface 3.

<9>重量体。
回転力付与装置4の特殊な構造として、重量体を使用した構造を図7、8において説明する。
上記したように、屋根兼止水面体2や屋根兼エネルギー吸収面体3は支点11を中心に回転自在に支柱1に取り付けてある。
その場合に屋根兼止水面体2や屋根兼エネルギー吸収面体3を支点11の一方に張り出す状態で取り付ける。
一方、支点11の他方には重量体5を取り付ける。
重量体5とはエレベータの釣合い重りと同様の機能を果たし、その重量によって支点11の他方に張り出した屋根の姿勢を維持する。
したがって、支点11の他方の重量体5の重要を除去すれば、屋根兼止水面体2、屋根兼エネルギー吸収面体3は姿勢を維持することができず、自らの重量によって支点11を中心に回転し、姿勢は傾斜してゆく。
<9> Weight body.
As a special structure of the rotational force applying device 4, a structure using a weight body will be described with reference to FIGS.
As described above, the roof / waterstop surface 2 and the roof / energy absorption surface 3 are attached to the column 1 so as to be rotatable about the fulcrum 11.
In that case, the roof / waterstop surface 2 and the roof / energy-absorbing surface 3 are attached in a state of overhanging one of the fulcrums 11.
On the other hand, the weight body 5 is attached to the other fulcrum 11.
The weight body 5 performs the same function as an elevator counterweight, and maintains the posture of the roof that projects to the other of the fulcrum 11 by its weight.
Therefore, if the importance of the other weight body 5 of the fulcrum 11 is removed, the roof / waterstop surface body 2 and the roof / energy absorption surface body 3 cannot maintain the posture, and rotate around the fulcrum 11 by their own weight. However, the posture is inclined.

<10>重量の調整。
重量体5の重量を減らせば、容易に屋根兼止水面体2、屋根兼エネルギー吸収面体3を回転させることができる。
そのために、重量体5を複数個の重量物を重ねたもので構成した場合には順次、重りを取り外してゆくことで重量を軽減させることができる。
複数個の重量物として、例えばコンクリートブロック、鉄塊、砂袋、土嚢、水を入れた箱のような簡単な部材を利用できる。
あるいは重量体5として、容器51に収納した流動体52によって構成する。
流動体52とは例えば水や砂、粒状体などを採用できる。
容器51にはバルブ53を取り付けておき、高潮などの襲来の予報を知ったら、担当者がバルブ53を開口して容器51から流動体52を短時間で排出する。
すると容器51内の重量が短時間で軽減して屋根兼止水面体2、屋根兼エネルギー吸収面体3を傾斜させることができる。
<10> Adjustment of weight.
If the weight of the weight body 5 is reduced, the roof / waterstop surface body 2 and the roof / energy absorption surface body 3 can be easily rotated.
For this reason, when the weight body 5 is formed by stacking a plurality of heavy objects, the weight can be reduced by sequentially removing the weights.
As a plurality of heavy objects, for example, simple members such as concrete blocks, iron blocks, sand bags, sandbags, boxes containing water can be used.
Alternatively, the weight body 5 is constituted by a fluid body 52 housed in a container 51.
As the fluid 52, for example, water, sand, a granular material, or the like can be adopted.
A valve 53 is attached to the container 51, and if a person knows a forecast of an attack such as a storm surge, the person in charge opens the valve 53 and discharges the fluid 52 from the container 51 in a short time.
Then, the weight in the container 51 can be reduced in a short time, and the roof / waterstop surface 2 and the roof / energy absorption surface 3 can be inclined.

<11>屋根側の重量の増加。
支点11の一方の重量体5の重量の軽減だけでなく、支点11の他方の屋根兼止水面体2、屋根兼エネルギー吸収面体3の重量を増加させる構造を採用することもできる。
その場合には屋根兼止水面体2、屋根兼エネルギー吸収面体3の内部に、その先端付近まで流路54を設置する。
この流路54と、重量体5としての容器51の排出口とを連結し、バルブ53を介在させておく。
すると、バルブ53を開いて重量体5の容器51内の流動体52を流出させれば、流動体52は流路54に流れ込み、屋根兼止水面体2や屋根兼エネルギー吸収面体3の側の重量が増加してゆく。
このように支点11の一方の重量体5の重量が減少し、それに反比例して支点11の他方の屋根兼止水面体2、屋根兼エネルギー吸収面体3の重量が増加するから、より迅速な回転を促すことができる。
屋根兼止水面体2の先端、すなわち回転時に地表面に接する位置にゴム袋のようなパッキン材55を設置した場合には、このパッキン材55の中空部と流路54を連結しておく。
すると重量体5の内部の流動体52が、パッキン材55の中空部に流入して膨張させるから、より水密性を向上させることができる。
<11> Increase in weight on the roof side.
Not only the weight of one weight body 5 of the fulcrum 11 can be reduced, but also the structure of increasing the weight of the other roof / water stop surface body 2 and the roof / energy absorption face body 3 of the fulcrum 11 can be adopted.
In that case, the flow path 54 is installed inside the roof and waterstop surface 2 and the roof and energy absorption surface 3 to the vicinity of the tip.
This flow path 54 and the discharge port of the container 51 as the weight body 5 are connected, and the valve 53 is interposed.
Then, if the valve 53 is opened and the fluid 52 in the container 51 of the weight body 5 is caused to flow out, the fluid 52 flows into the flow path 54, and is on the roof / water stop surface 2 or roof / energy absorption surface 3 side. Weight increases.
Thus, the weight of one weight body 5 of the fulcrum 11 decreases, and the weight of the other roof / water stop surface body 2 and roof / energy absorption surface body 3 of the fulcrum 11 increases in inverse proportion to the weight. Can be encouraged.
When a packing material 55 such as a rubber bag is installed at the tip of the roof and waterstop body 2, that is, at a position in contact with the ground surface during rotation, the hollow portion of the packing material 55 and the flow path 54 are connected.
Then, since the fluid 52 inside the weight body 5 flows into the hollow portion of the packing material 55 and expands, the water tightness can be further improved.

<12>高潮の襲来時の作動。
上記した屋根兼止水面体2、屋根兼エネルギー吸収面体3の作動をまとめて説明する。
<12> Operation during storm surge.
The operation of the roof / waterstop surface 2 and the roof / energy absorption surface 3 will be described together.

<13>屋根兼止水面体2のみの構造。
海岸線や河川に沿って屋根兼止水面体2のみを配置した場合について説明する。
通常は、屋根兼止水面体2は支柱1の上部にほぼ水平の姿勢を保って支持されているから、日差しや雨をさえぎる屋根として利用でき、海岸線や河川に沿って憩いの場所を提供することができる。
高潮、津波、河川の水位の異常な上昇が発生する可能性が高くなった場合には、回転力付与装置4を作動して、支点11を介して支柱1に回転自在に取り付けた屋根兼止水面体2を回転させ、高潮などの来る海側へ向けて対面させる。
回転力付与装置4として、容器51内に流動体52を収納した構造を採用した場合には、バルブ53を開放してその流動体52を容器51外に排出して重量体5の重量を軽減する。
すると支点11の他方に位置している屋根兼止水面体2は、その先端が地表面に設置するまで回転する。
屋根兼止水面体2は、貫通孔の存在しない無孔体で構成してあるから、高潮、あるいは小規模の津波、河川の水位の上昇を、その位置で阻止することができ、陸側への水の侵入、損害の発生を阻止することができる。
<13> The structure of only the roof and water stop surface 2.
A case where only the roof and water stop body 2 is arranged along the coastline or river will be described.
Usually, the roof / waterstop body 2 is supported on the upper part of the support column 1 in a substantially horizontal posture, so that it can be used as a roof to block sunlight and rain, and provides a place for rest along the coastline and river. be able to.
When there is a high possibility that storm surges, tsunamis, and abnormal rises in river water levels will occur, the rotational force imparting device 4 is actuated to allow the roof to be fixed to the column 1 via the fulcrum 11 so as to rotate freely. Rotate the water surface 2 and face it toward the sea side where storm surges come.
When the structure in which the fluid 52 is housed in the container 51 is adopted as the rotational force applying device 4, the valve 53 is opened and the fluid 52 is discharged out of the container 51 to reduce the weight of the weight body 5. To do.
Then, the roof and water stop surface body 2 located on the other side of the fulcrum 11 rotates until its tip is installed on the ground surface.
Since the roof / waterstop body 2 is composed of a non-porous body with no through-holes, it can prevent storm surges, small-scale tsunamis, and river water levels from rising to the land side. Water intrusion and damage can be prevented.

<14>屋根兼エネルギー吸収面体3を設置した構造。
陸側に屋根兼止水面体2を、海側に屋根兼エネルギー吸収面体3を配置した場合について説明する。
通常は、屋根兼止水面体2と屋根兼エネルギー吸収面体3は支柱1の上部にほぼ水平の姿勢を保って支持されているから、日差しや雨をさえぎる屋根として利用でき、海岸線や河川に沿って憩いの場所を提供することができる。
高潮、津波、河川の水位の異常な上昇が発生する可能性が高くなった場合には、回転力付与装置4を作動して、支点11を介して支柱1に回転自在に取り付けた屋根兼止水面体2と屋根兼エネルギー吸収面体3を回転させ、高潮などの来る海側へ向けて対面させる。
回転力付与装置4として、容器51内に流動体52を収納した構造を採用した場合には、バルブ53を開放してその流動体52を容器51外に排出して重量体5の重量を軽減する。
すると支点11の他方に位置している屋根兼止水面体2や屋根兼エネルギー吸収面体3は、その先端が地表面に設置するまで回転する。
海側において海水の上昇に対向して設置された屋根兼エネルギー吸収面体3は、分散した貫通孔を開設した有孔体で構成した面体であるから、上昇した海水の通過を阻止することはできない。
しかし上昇した海水が屋根兼エネルギー吸収面体3の貫通孔を通過することによって、海水のエネルギーが大幅に吸収される。
エネルギーの吸収された海水は、陸側に設置した屋根兼止水面体2の表面に到達する。
屋根兼止水面体2は、貫通孔の存在しない無孔体で構成してあるから、エネルギーがすでに低下した水位の上昇を、その位置で阻止することができ、陸側への水の侵入、損害の発生を阻止することができる。
<14> A structure in which the roof and energy absorbing face 3 is installed.
The case where the roof and water stop surface body 2 is disposed on the land side and the roof and energy absorption surface body 3 is disposed on the sea side will be described.
Normally, the roof / waterstop surface 2 and the roof / energy absorption surface 3 are supported on the upper part of the support column 1 in a substantially horizontal position, so that they can be used as roofs to block sunlight and rain, and along coastlines and rivers. Can provide a place of relaxation.
When there is a high possibility that storm surges, tsunamis, and abnormal rises in river water levels will occur, the rotational force imparting device 4 is actuated to allow the roof to be fixed to the column 1 via the fulcrum 11 so as to rotate freely. The water surface body 2 and the roof / energy absorption surface body 3 are rotated so as to face each other toward the sea side where storm surges come.
When the structure in which the fluid 52 is housed in the container 51 is adopted as the rotational force applying device 4, the valve 53 is opened and the fluid 52 is discharged out of the container 51 to reduce the weight of the weight body 5. To do.
Then, the roof and water stop surface body 2 and the roof and energy absorption surface body 3 located on the other side of the fulcrum 11 rotate until their tips are installed on the ground surface.
Since the roof and energy absorption face 3 installed facing the rise of seawater on the sea side is a face made of a perforated body with dispersed through-holes, it cannot prevent the passage of the risen seawater. .
However, the seawater that has risen passes through the through-holes of the roof-and-energy-absorbing face body 3, so that the energy of the seawater is significantly absorbed.
The seawater in which the energy has been absorbed reaches the surface of the roof / waterstop body 2 installed on the land side.
Since the roof and still water surface body 2 is composed of a non-porous body having no through-holes, it is possible to prevent an increase in the water level at which energy has already been reduced at that position, Damage can be prevented from occurring.
