Description
本発明は、例えば潮の干満、津波の押し寄せ等に基づく水位の変化が生じた際、これに即応した浮上作用が奏されるようにした堤防体に関する。 The present invention relates to a levee body in which, when a change in water level occurs due to, for example, tides or tsunami, a levitation action that responds promptly.
従来、潮の干満、津波の押し寄せ等に基づく水位の変化が生じた際、これによる影響を防止する手段としては、麻袋等の丈夫な袋に土砂等の充填物を入れた土嚢を積み上げて堤防を嵩上げして決壊を防止することが昔から行われている。 然し乍、土嚢の充填物である土壌を緊急事態時に即座に用意することは、現代においては殆ど不可能である。 Conventionally, when the water level changes due to tides and tsunami, as a means to prevent the influence of this, a sandbag filled with sand and other fillers is piled up on a strong bag such as a hemp bag and the embankment It has been practiced for a long time to raise the height and prevent breakage. However, it is almost impossible in modern times to immediately prepare the soil, which is a sandbag filling, in an emergency.
そこで、土嚢を用いない方式として、堤防の嵩上げを所定の形状に形成した土木資材を用いる様に構成したものがある（例えば特許文献１及び特許文献２参照。）。 これは本願と同一の発明者及び同一出願人に係るものである。 そして、所定の形状に形成されている土木資材を、決壊が予想される堤防の上面に組み込むようにしたものである。 Therefore, as a method that does not use a sandbag, there is one configured to use a civil engineering material in which the embankment is formed in a predetermined shape (see, for example, Patent Document 1 and Patent Document 2). This relates to the same inventor and the same applicant as the present application. Then, the civil engineering material formed in a predetermined shape is incorporated into the upper surface of the levee where breakage is expected.
上述したような土木資材を組み込むようにしたものであると、堤防の決壊が予想される時にその組立作業上の迅速対応性の点においてやや欠けることがある。 そして、その嵩上げ高さは定まったものに限定され、これの調節を行うことは通常は出来なかった。 When the civil engineering materials as described above are incorporated, there may be a shortage in terms of quick correspondence in assembling work when a levee break is expected. And the raised height is limited to a fixed height, and it was not usually possible to adjust this.
本発明はこのような従来の問題を排し、例えばベニスのように潮の満ち干による影響が恒久的に発生する都市等における堤防として最適とするように、潮の満ち干に起因する水位の変化に基づく昇降作用、すなわち、浮き沈み作用が奏されるようにした全く新しいタイプの堤防の提供を図ったものである。 具体的に言えば、海側の水位が高まった際には、堤防自体がこれに即応して上昇することによって、陸側の水位は常に一定に保たれるような作用が奏されるようにした新規の堤防を提供するものである。 The present invention eliminates such a conventional problem and, for example, optimizes the level of water caused by tides so as to be optimal as a dike in cities such as Venice where tides are permanently affected. The aim is to provide a completely new type of embankment that is capable of raising and lowering based on change, that is, ups and downs. Specifically, when the water level on the sea side increases, the embankment itself rises in response to this, so that the water level on the land side is always kept constant. New embankments are provided.
本発明は、内部空間に水の侵入を妨げないような形態を具えた堤防の基礎となる構造体Ｍの上面に、堤防の上面構築を成すための土台としての役割を果たす浮遊基体１を位置させると共に、当該浮遊基体１の下面の海側寄りと陸側寄りとに、浮遊制御用海側垂下体５及び浮遊制御用陸側垂下体６を夫々垂設すると共に、当該垂下体５及び６の全長を摺動自在に受け入れるための縦溝孔７及び８を構造体Ｍの海側と陸側に設け、潮が満ちることによって浮遊基体１に浮力が生じてこれを上昇させた際、上記浮遊制御用陸側垂下体６を介して、浮遊基体１の浮上に基づき形成される構造体Ｍとの隙間と、構造体Ｍに設けられている海側と陸側とを連通させるトンネル状連通部とが封鎖されるように構成した増水すると浮上する堤防に係る。 In the present invention, a floating base body 1 that serves as a foundation for constructing a top surface of a dike is positioned on the top surface of a structure M that forms a foundation of a dike that has a shape that does not prevent water from entering the internal space. In addition, the floating control sea-side suspended body 5 and the floating control land-side suspended body 6 are respectively suspended on the lower surface of the floating base 1 near the sea and the land, and the suspended bodies 5 and 6 are suspended. When the vertical groove holes 7 and 8 for slidably receiving the full length of the structure M are provided on the sea side and the land side of the structure M, and the tide is full, buoyancy is generated in the floating base 1 and raised. A tunnel-like communication that connects the gap between the floating body 1 and the structure M formed based on the floating of the floating base 1 and the sea side and the land side provided in the structure M through the floating control land-side hanging body 6. This is related to the embankment that rises when the water is increased so that it is sealed off.
本発明は請求項１に記載のような構成の採用に基づき、潮が満ちることによって浮遊基体１に浮力が生じてこれを上昇させた際、上記浮遊制御用陸側垂下体６を介して、浮遊基体１の浮上に基づき形成される構造体Ｍとの隙間と、構造体Ｍに設けられている海側と陸側とを連通させるトンネル状連通部とが封鎖されるため、海側の水位が上昇しても陸側の水位は常に一定したものとされる。 従って、潮の満ち干に即応させて陸側の浸水に対する対応を採ることなく、安定したものとされるから、例えばベニスのように潮の干満に左右される土地に対する堤防として最適とするものである。 The present invention is based on the adoption of the configuration as described in claim 1, and when the floating base 1 is lifted due to the tide, the floating base 1 is raised through the floating control land-side hanging body 6. Since the gap with the structure M formed based on the floating of the floating substrate 1 and the tunnel-like communication portion that connects the sea side and the land side provided in the structure M are sealed, the water level on the sea side Even if the rises, the water level on the land side is always constant. Therefore, since it is stable without taking measures against inundation on the land side by promptly responding to tides, it is optimal as a dike for land that is affected by tides, such as Venice. is there.
更に、本発明は、内部空間に水の侵入を妨げないような形態を具えた堤防の基礎となる構造体Ｍを用い、海側と陸側とを連通させるトンネル状連通部を具えたものとしてあるから、これらの部分は漁礁として最適なものとされ、魚類の繁殖作用にも貢献することとなる。 Furthermore, the present invention uses a structure M as a foundation of a dike having a form that does not prevent water intrusion in the internal space, and includes a tunnel-like communication portion that allows communication between the sea side and the land side. Therefore, these parts are considered to be optimal as fishing reefs, and contribute to fish breeding.
図において、Ｍは堤防の基礎となる構造体であって、内部に空間が形成される構造体、例えば特開２００１−３５５２５９号公報に掲載の「構造体」を用いて形成する等成して、構造体の内部に対する水侵入を妨げないような形態を呈し、換言すると、堤防内外（構造体内外）の水循環性を阻害することのないように構成することにより、漁礁としての機能が果たされるような形態に構成してある。 In the figure, M is a structure that is the foundation of a dike, and is formed using a structure in which a space is formed, for example, a “structure” described in JP-A-2001-355259. It has a form that does not prevent water intrusion to the inside of the structure, in other words, it functions as a fishing reef by configuring it so as not to disturb the water circulation inside and outside the dike (inside and outside the structure) It is comprised in such a form.
そして、当該構造体Ｍの中央部分には、海側と陸側とを連通させるトンネル状連通部ｍを形成してある。 And in the center part of the said structure M, the tunnel-shaped communication part m which connects the sea side and the land side is formed.
１は独立気泡を具える等成した材料で形成した浮遊基体であって、堤防の上面構築を成すための土台としての役割を果たすものである。 そして、当該浮遊基体１の上面中央部には客土２を介在させて遊歩用または車両用の道路３が、またその両側部には必要に応じて植林４等を成すことにより、緑化施設が形成してある。 Reference numeral 1 denotes a floating base formed of an equal material including closed cells, which plays a role as a foundation for constructing the upper surface of the bank. Then, a walking or vehicle road 3 is interposed in the center of the upper surface of the floating base 1 with a land 2 and afforestation 4 is formed on both sides thereof as necessary, so that a greening facility is provided. It is formed.
そして、上記した浮遊基体１は、上記材料の使用等に基づき、海水が満ちた際には浮遊するような浮力性能が付与されている。 更に、当該浮遊基体１の下面両側部にはその長手方向に沿うように、浮遊制御用海側垂下体５及び浮遊制御用陸側垂下体６が夫々垂設してある。 And the above-mentioned floating base | substrate 1 is provided with the buoyancy performance which floats when seawater fills based on use of the said material. Further, a floating control sea-side suspended body 5 and a floating control land-side suspended body 6 are suspended from both sides of the lower surface of the floating base body 1 along the longitudinal direction thereof.
一方、構造体Ｍの対応箇所には、当該垂下体５及び６を摺動自在に受け入れ可能とする縦溝孔７及び８が形成してある。 そして、当該縦溝孔７に挿入される浮遊制御用海側垂下体５には、構造体Ｍに対して海側からの水流入を阻害しないための流通用開口５ａが開設されている。 On the other hand, longitudinal grooves 7 and 8 are formed at corresponding portions of the structure M so that the hanging bodies 5 and 6 can be slidably received. The floating control sea-side drooping body 5 inserted into the vertical groove hole 7 is provided with a flow opening 5a for preventing the structure M from flowing in water from the sea side.
更に、前記縦溝孔８に挿入される浮遊制御用陸側垂下体６のほぼ中央部には、開口状態にあるトンネル状連通部ｍと連通する開口面部６ａが開設されている。 従って、その上端寄り板面６ｂは浮遊基体１の浮上に基づき形成される隙間を封鎖するための閉鎖用板面として機能し、その下端寄り板面６ｃは、同上浮上時におけるトンネル状連通部ｍの封鎖用板面として機能する様に構成してある。 Furthermore, an opening surface portion 6a communicating with the tunnel-like communication portion m in an open state is opened at a substantially central portion of the floating control land-side hanging body 6 inserted into the vertical groove hole 8. Therefore, the upper end side plate surface 6b functions as a closing plate surface for sealing the gap formed based on the floating of the floating base 1, and the lower end side plate surface 6c is the tunnel-like communication portion m at the time of rising. It is comprised so that it may function as a sealing plate surface.
図１に示すように、浮遊基体１に対して海水の浮力が働かないために構造体Ｍに対して接している状態あっては、本発明に係る堤防の海側と陸側は同一水位（通常時水位）に保たれている。 As shown in FIG. 1, the sea side and the land side of the levees according to the present invention are at the same water level (when the buoyancy of seawater does not act on the floating base 1 so that it is in contact with the structure M. Normal water level).
次に、図２に示すように、潮が満ちることによって浮遊基体１に対して海水による浮力が及んでこれを上昇させた際、これに垂設されている浮遊制御用海側垂下体５及び浮遊制御用陸側垂下体６も連動して引き上げられることとなる。 そのため、陸側垂下体６における上端寄り板面６ｂが、浮遊基体１の浮上に基づき形成される隙間を封鎖するための閉鎖用板面として機能する。 更に、その下端寄り板面６ｃが、同上浮上時におけるトンネル状連通部ｍの封鎖用板面として機能する。 Next, as shown in FIG. 2, when the tide is filled with buoyancy caused by seawater to the floating base body 1 and lifts it, the floating control sea-side suspended body 5 suspended from the floating base body 1 and The land-side hanging body 6 for floating control is also pulled up in conjunction. Therefore, the upper end side plate surface 6 b in the land-side hanging body 6 functions as a closing plate surface for sealing a gap formed based on the floating of the floating base body 1. Further, the plate surface 6c near the lower end functions as a blocking plate surface of the tunnel-like communication portion m at the time of rising.
上記の各封鎖に基づき、海側の水位が上がっても、これが陸側に流れ込むことが阻止されているため、陸側の水位が変化することなく「通常時水位」を保つこととなる。 換言すると潮の干満に基づく海側の水位変化とは関わりなく、陸側の水位は常に「通常時水位」に保たれることとなる。 Based on the above blockades, even if the water level on the sea side rises, the water level on the land side is prevented from flowing into the land side, so that the “normal water level” is maintained without changing the water level on the land side. In other words, the water level on the land side is always kept at the “normal water level” regardless of the sea level change due to the tidal range.
一方、海側の流れは堤防の基礎となる構造体Ｍ内に対する流入・流出性は様炊けられないため、魚の出入りとされ、結局、構造体Ｍは魚の産卵場、所謂漁礁として機能することとなる。 On the other hand, the flow on the sea side cannot be cooked in and out of the structure M that is the foundation of the dike, so it is considered as a fish spawning ground, so-called fishing reef. Become.
