Description
本発明は、ユニット式防潮壁に関するものである。
The present invention relates to a unit type tide barrier.
昨今発生している地震による津波や台風等による高潮で甚大な被害が発生しているが、その対応策が依然と土木による防潮堤の建設が主体であり、現在は人員及び資材不足に伴う高コスト化、原材料とエネルギーの大量消費、建設期間の長期化、環境、景観等の理由により建設が遅滞している。
Great damage has occurred due to storm surges caused by tsunamis and typhoons caused by recent earthquakes, but the countermeasures are still mainly construction of seawalls with civil engineering. Construction is delayed due to cost, mass consumption of raw materials and energy, prolonged construction period, environment and landscape.
東日本大震災では、発生以前に建設された既存の施設以上の高さの波が発生したことにより既存の防潮堤では防御できず、今後発生し得る可能性の高い東南海沖地震に対しても、想定の予想が難しく、既存の施設での対策だけでは困難である。
In the case of the Great East Japan Earthquake, the existing seawall could not be protected due to the occurrence of waves higher than the existing facilities constructed before the occurrence, and the Tonankai-oki earthquake, which is likely to occur in the future, It is difficult to predict the assumption, and it is difficult to take measures only at existing facilities.
現在地震が発生している最中に津波が接近して来た場合や想定以上の地震が発生した場合、津波が来る以前に既存の防潮堤は破壊されていることも明らかになっているため、現在の研究機関で対策を検討している段階である。
If a tsunami is approaching during an earthquake or an earthquake that exceeds the expected level, the existing seawall is destroyed before the tsunami arrives. This is the stage where current research institutions are considering countermeasures.
特許文献１や特許文献２の開示された内容やその他類似したものは、長時間海中に設置されたままでいるために、いざ使用する際に十分対応できるかという疑問が残る。また防潮堤自体の強度や高さ等様々な基準が変更される昨今、一度設置してしまうと変更された新たな基準に沿った柔軟な対応が出来ない。補助的ではあるが本発明は、それらの問題点を解決するためのものである。
Since the contents disclosed in Patent Document 1 and Patent Document 2 and other similar contents remain installed in the sea for a long time, there remains a question as to whether or not they can be used sufficiently. In addition, since various standards such as the strength and height of the seawall itself have been changed, once installed, it is not possible to flexibly respond to the changed new standards. Although ancillary, the present invention is intended to solve these problems.
上述のように既存の防潮堤施設では、仮に想定内の波であったとしても、資源エネルギーの大量消費は当然ながら、自然環境の喪失、建設問題で地域住民との景観等による問題が発生する。また嵩上げ工事を行うにしても同様の問題がある。
As mentioned above, even if the existing seawall facility is an expected wave, a large amount of resource and energy will be consumed, but natural environment loss and construction problems will cause problems with local residents. . In addition, there is a similar problem even if the raising work is performed.
本発明は上述の問題点を鑑みなされたものであり、従来の施設と比較して軽量の為に運搬、保管、設置、撤収が可能であるため、自然環境や景観等の保護ができるユニット式防潮壁を提供することを目的とする。
The present invention has been made in view of the above-mentioned problems, and can be transported, stored, installed, and withdrawn because of its light weight compared to conventional facilities, so that it can protect the natural environment, landscape, etc. The purpose is to provide a seawall.
補助的ではあるけれども、設置された施設の強度や高さ等様々な基準が変更されるが、本発明は変更された新たな基準に沿った対応が出来るユニット式防潮壁を提供することを目的とする。
Although various standards such as the strength and height of the installed facilities are changed although it is ancillary, the present invention aims to provide a unit type seawall that can respond to the changed new standards. And
本発明はそれ以外に、柔軟性が高いため、耐震可能なユニット式防潮壁を提供することを目的とする。
Another object of the present invention is to provide a unit type seawall that can be earthquake-resistant because of its high flexibility.
上述の課題を解決するために、本発明によるユニット式防潮堤は、吸水性ポリマーが収納されるとともに、内部に気体又は液体が充填可能な気密室が相互に連通した状態で、縦方向及び横方向に複数列配設された前記ユニット式防潮壁であって、前記気密室へ気体又は液体を供給する手段と、前記気密室に設けられて前記気密室に気体又は液体を充填する注入口と、前記気密室に設けられて前記気密室の気体又は液体を排出する排出口と、前記気密室の破損防止をするために、前記気密室内の圧力を減圧するための安全弁と、前記気密室及び前記気密室の後方側に位置する隣接の気密室との間を連通させる管路内の圧縮された気体又は液体を前記気密室の後方側に位置する隣接の気密室へ移動するのは許可し、その逆方向への移動を阻止する逆流防止弁と、前記ユニット式防潮壁の少なくとも前面に設けられて衝撃を吸収するための防御板と、前記気密室の後方側に設けられた気体又は液体が未充填の複数個の気密室と、少なくとも前記気密室及び前記未充填の気密室を土台に固定する固定手段からなっていることを特徴とする。
In order to solve the above-mentioned problems, a unit type seawall according to the present invention includes a water-absorbing polymer and a longitudinal direction and a lateral direction in a state where airtight chambers that can be filled with gas or liquid are communicated with each other. The unit type tide barriers arranged in a plurality of rows in a direction, and means for supplying gas or liquid to the hermetic chamber, and an inlet provided in the hermetic chamber for filling the gas hermetic chamber with gas or liquid A discharge port provided in the hermetic chamber for discharging gas or liquid in the hermetic chamber, a safety valve for reducing the pressure in the hermetic chamber in order to prevent breakage of the hermetic chamber, and the hermetic chamber and It is allowed to move the compressed gas or liquid in the pipe line communicating with the adjacent hermetic chamber located on the rear side of the hermetic chamber to the adjacent hermetic chamber located on the rear side of the hermetic chamber. Prevent movement in the opposite direction A flow prevention valve, a protection plate provided at least on the front surface of the unit-type tide barrier to absorb an impact, and a plurality of gas-tight chambers which are not filled with gas or liquid provided on the rear side of the air-tight chamber; And at least the hermetic chamber and the unfilled hermetic chamber are characterized by comprising fixing means for fixing to a base .
本発明の効果は、吸水性ポリマー１８が収納されるとともに、内部に気体又は液体が充填可能な気密室２が相互に連通した状態で、縦方向及び横方向に複数列配設されたユニット式防潮壁１であって、気密室２へ気体又は液体を供給する手段１６と、気密室２に設けられて気密室２に気体又は液体を充填する注入口３と、気密室２に設けられて気密室２の気体又は液体を排出する排出口４と、気密室２の破損防止をするために、気密室２内の圧力を減圧するための安全弁５と、気密室２ａ、２ｄ及び気密室２ａ、２ｄの後方側に位置する隣接の気密室２ｂ、２ｃ、２ｅ、２ｆとの間を連通させる管路内の圧縮された気体又は液体を気密室２ａ、２ｄの後方側に位置する隣接の気密室２ｂ、２ｃ、２ｅ、２ｆへ移動するのは許可し、その逆方向への移動を阻止する逆流防止弁６と、ユニット式防潮壁１の少なくとも前面に設けられて衝撃を吸収するための防御板７と、気密室２の後方側に設けられた気体又は液体が未充填の複数個の気密室８ａ、８ｂ、８ｃ、８ｄと、少なくとも気密室２及び未充填の気密室８を土台に固定する固定手段９からなっていることを特徴とし、津波や高潮などによる衝突の衝撃を気密室２内の圧力の変動と吸水性ポリマー１８による気密室の重量増加による安定性を利用して、吸収緩和及び反発力で防御するという効果を奏する。尚、吸水性ポリマー１８の状態は、運搬、保管、撤収時は粉体で、設置時は加水された流動体になっているので、軽量化に寄与するという効果がある。
The effect of the present invention is that a unit type in which a plurality of rows are arranged in the vertical direction and the horizontal direction in a state where the water-absorbing polymer 18 is housed and the airtight chambers 2 in which a gas or a liquid can be filled are in communication with each other. The tide wall 1 is a means 16 for supplying gas or liquid to the hermetic chamber 2, an inlet 3 provided in the hermetic chamber 2 for filling the gas or liquid into the hermetic chamber 2, and provided in the hermetic chamber 2. A discharge port 4 for discharging the gas or liquid in the hermetic chamber 2, a safety valve 5 for reducing the pressure in the hermetic chamber 2 in order to prevent damage to the hermetic chamber 2, and the hermetic chambers 2a and 2d and the hermetic chamber 2a 2d, the compressed gas or liquid in the pipe line communicating with the adjacent hermetic chambers 2b, 2c, 2e, 2f located on the rear side of 2d Permitted to move to closed rooms 2b, 2c, 2e, 2f and vice versa Is not filled with a backflow prevention valve 6 that prevents the movement of the gas, a protection plate 7 that is provided at least on the front surface of the unit-type tide wall 1 and absorbs an impact, and a gas or liquid provided on the rear side of the hermetic chamber 2 A plurality of hermetic chambers 8a, 8b, 8c, 8d, and fixing means 9 for fixing at least the hermetic chamber 2 and the unfilled hermetic chamber 8 to the base . There is an effect that the impact is prevented by absorption relaxation and repulsive force by utilizing the stability due to the fluctuation of the pressure in the hermetic chamber 2 and the increase in the weight of the hermetic chamber by the water absorbing polymer 18. The state of the water-absorbing polymer 18 is a powder at the time of transportation, storage, and withdrawal, and is a fluid that is hydrolyzed at the time of installation, so that it contributes to weight reduction.
ユニット式防潮壁１の気密室２及び未充填の気密室８は、単体自体の大きさや気密室２及び未充填の気密室８の設置数を調整できる上に、気密室２、８自体を階層構造にすることできるため、設置場所の状況に応じて調整利用ができるという効果を奏する。
The hermetic chamber 2 and the unfilled hermetic chamber 8 of the unit type tide barrier 1 can be adjusted in size and the number of the hermetic chambers 2 and the unfilled hermetic chambers 8 can be adjusted. Since it can be made into a structure, there exists an effect that adjustment use can be performed according to the condition of an installation place.
従来の現場建設方式と異なり、工場など建設現場以外でユニット式防潮壁１を製造することが可能という効果を奏する。
Unlike the conventional site construction method, the unit type seawall 1 can be manufactured outside the construction site such as a factory.
ユニット式防潮壁１自体が従来の施設と比較して軽量の為に、運搬、保管、設置、撤収が可能なため、設置現場には土台建設及びユニット式防潮壁１を固定し、海岸線に並行で横方向に配設するユニット式防潮壁１同士を結束するために磁気を利用した固定手段９の設置のみであることにより、従来の施設より環境、景観等の保護化ができる。よって高潮や津波が発生する前に短時間で設置することができる。また一部の重要拠点では、既存施設の嵩上げ工事を行っており、補助的ではあるが本発明は、それらの問題点の解決をする一翼のものにできるという効果を奏する。
Since the unit type tide wall 1 itself is lighter than conventional facilities, it can be transported, stored, installed, and withdrawn. Therefore, the foundation construction and the unit type tide wall 1 are fixed at the installation site and parallel to the coastline. By simply installing the fixing means 9 using magnetism to bind the unit-type tide walls 1 arranged in the horizontal direction, it is possible to protect the environment, scenery, etc. from the conventional facilities. Therefore, it can be installed in a short time before storm surge or tsunami occurs. Moreover, in some important bases, the existing facilities are raised, and although supplementary, the present invention has an effect that it can be made into a single wing that solves these problems.
逆流防止弁６の設置は、気密室２に吸気用の注入口３の部分と、気密室２破損防止のための安全弁５の部分と、連通されている気密室２ａ、２ｂ、２ｃ、２ｄ、２ｅ、２ｆの管路内に設置されており、注入口３と安全弁５の部分以外の逆流防止弁６の役割は、衝撃を受けた気密室２ａ、２ｄが圧縮された結果、逆流防止弁６を通じて気体又は液体が気密室２ａ、２ｄの後方側に位置する隣接の気密室２ｂ、２ｃ、２ｅ、２ｆに排出することにより、気密室２ａ、２ｄの圧力が下降することによって吸収緩和され、加えて気体又は液体排出先の気密室の後方側に位置する隣接の気密室２ｂ、２ｃ、２ｅ、２ｆの圧力が上昇することによって反発作用が起こり、衝突した波を衝突方向と反対方向に反発力を得るためと、衝撃により仮に気密室２ａ、２ｄが破損しても被害を最小限に留める対策として設置されており、逆流防止弁６の強度は、安全弁５の逆流防止弁６の蓋の強度が一番強く、気体又は液体自体が別の気密室２ｂ、２ｃ、２ｅ、２ｆへ移動するごとに逆流防止弁６の蓋の強度を少なくとも同等若しくは順次大きく設定することにより、気密室２の破損防止をするという効果を奏する。
The backflow prevention valve 6 is installed in the airtight chamber 2 by the portion of the inlet 3 for intake, the portion of the safety valve 5 for preventing the airtight chamber 2 from being damaged, and the airtight chambers 2a, 2b, 2c, 2d, 2e and 2f are installed in the pipelines, and the role of the backflow prevention valve 6 other than the portions of the inlet 3 and the safety valve 5 is that the airtight chambers 2a and 2d that have received impacts are compressed, and the backflow prevention valve 6 The gas or liquid is discharged to the adjacent airtight chambers 2b, 2c, 2e, and 2f located on the rear side of the airtight chambers 2a and 2d through the gas, and is absorbed and relaxed by the pressure in the airtight chambers 2a and 2d decreasing. Thus, a repulsive action occurs when the pressure in the adjacent airtight chambers 2b, 2c, 2e, and 2f located on the rear side of the gas or liquid discharge destination is increased, and the rebound force is generated in the direction opposite to the collision direction. To obtain the airtight chamber 2a due to impact It is installed as a measure to keep damage to a minimum even if 2d breaks. The strength of the backflow prevention valve 6 is the strongest of the cover of the backflow prevention valve 6 of the safety valve 5, and the gas or liquid itself is different. By setting the strength of the lid of the backflow prevention valve 6 at least equal to or sequentially larger every time it moves to the hermetic chambers 2b, 2c, 2e, and 2f, the hermetic chamber 2 is prevented from being damaged.
現在地震が発生している最中に津波が接近して来た場合や想定以上の地震が発生した場合、津波が来る以前に既存の防潮堤は破壊されていることも明らかになっているために、土台とユニット式防潮壁１を分離する対策若しくは免震機能の付いた防潮堤の設置が必要であるが、現在のところ研究中という状態であり、本発明は柔軟性が高いため、その対応策の一案になるという効果を奏する。
If a tsunami is approaching during an earthquake or an earthquake that exceeds the expected level, the existing seawall is destroyed before the tsunami arrives. In addition, it is necessary to take measures to separate the base and the unit type seawall 1 or to install a seawall with seismic isolation function. However, the present invention is currently under study, and the present invention is highly flexible. There is an effect that it becomes a plan of countermeasures.
気密室２の内部には気体又は液体が充填可能となっており、以下からの説明は主として気体を使用した場合のユニット式防潮壁に関する説明であるが、液体だけや気体及び液体の併用使用をしてもよい。
The inside of the hermetic chamber 2 can be filled with gas or liquid, and the following explanation is mainly about the unit type tide barrier when gas is used, but only the liquid or the combined use of gas and liquid is used. May be.
本発明によれば、津波や高潮などによる衝突の衝撃がユニット式防潮堤にぶつけられた場合、前記ユニット式防潮堤の前方側に位置する気密室が圧縮された結果、逆流防止弁から気体又は液体が前記前方側に位置する気密室の後方側に位置する隣接の気密室に排出されることにより、前記前方側に位置する気密室の圧力が下降することによって吸収緩和され、加えて気体又は液体の排出先の前記前方側に位置する気密室の後方側に位置する隣接の気密室の圧力が上昇することによって反発作用が起こり、衝突した波を衝突方向と反対方向に反発するという利点がある。また前記ユニット式防潮堤は気体又は液体を充填されて膨張させるものであることから設置が容易であり、また撤収するときにも気体又は液体を排出縮小して運搬保管が可能である。
According to the present invention, when the impact of a collision due to a tsunami or storm surge hits the unit type seawall, the airtight chamber located on the front side of the unit type seawall is compressed, so that the gas or By discharging the liquid to the adjacent hermetic chamber located on the rear side of the hermetic chamber located on the front side, the absorption of the liquid is reduced when the pressure of the hermetic chamber located on the front side decreases, and in addition, the gas or There is an advantage that a repulsive action occurs by increasing the pressure of an adjacent hermetic chamber located on the rear side of the hermetic chamber located on the front side of the liquid discharge destination, and the colliding waves are repelled in the direction opposite to the collision direction. is there. Further, the unit type seawall is filled with gas or liquid to be expanded, so that it can be easily installed, and when it is withdrawn, it can be transported and stored by discharging and reducing the gas or liquid.
また地震が発生している最中に津波が接近して来た場合や想定以上の地震が発生した場合、津波が来る以前に既存の防潮堤は破壊されていることも明らかになっているが、本発明によれば土台とユニット式防潮壁の固定手段は、磁気を利用した固定手段を用いているため、柔軟性が高く、既存の防潮堤より破壊される可能性が低くなる。
It is also clear that if a tsunami is approaching during an earthquake, or if an earthquake more than expected occurs, the existing seawall is destroyed before the tsunami arrives. According to the present invention, since the fixing means for the base and the unit type seawall is a magnetizing means, the flexibility is high and the possibility of being destroyed from the existing seawall is low.
ユニット式防潮壁１は、気密室２内に圧縮された気体又は液体を衝突の衝撃によって変動させることを利用して吸収緩和及び反発力で防御するため、短時間で高圧力下の気密室２を作る必要性があることにより、伸縮性があり強靭な合成樹脂やゴムを被覆した破損しにくい合成繊維が望ましく、例えばエアバックやパラシュート等に使用されている素材を使用するのが望ましい。
The unit type tide barrier 1 protects the gas or liquid compressed in the hermetic chamber 2 with absorption relaxation and repulsive force by changing the gas or liquid due to the impact of the collision, and therefore the hermetic chamber 2 under high pressure in a short time. Therefore, it is desirable to use a stretchable and tough synthetic resin or a synthetic fiber that is hard to break, such as a material used for airbags or parachutes.
主として気体を基本的に利用するために外気利用となり、気密室２へ気体を供給する手段１６としてエアポンプを利用するが、電源喪失した場合も考慮して、外部電源の設置が望ましい。またそれ以外に気体を使用する場合は携帯保管した可搬式高圧容器も利用する。そのため各々気密室２ａ、２ｂ、２ｃ、２ｄ、２ｅ、２ｆには、外部からの充填用の注入口３と、排出用の排出口４と、気密室破損防止のための安全弁５と、連通させる気密室２の管路内に逆流防止弁６が設置されている。
The air pump is mainly used as the means 16 for supplying the gas to the hermetic chamber 2 because the air is mainly used for the basic use of the gas. However, it is desirable to install an external power source in consideration of the loss of the power source. In addition, when gas is used, a portable high-pressure container stored in a portable manner is also used. Therefore, each of the airtight chambers 2a, 2b, 2c, 2d, 2e, and 2f is communicated with an inlet 3 for filling from the outside, a discharge port 4 for discharging, and a safety valve 5 for preventing damage to the hermetic chamber. A backflow prevention valve 6 is installed in the pipeline of the hermetic chamber 2.
設置場所の状況に応じて、気密室２及び未充填の気密室８単体自体の大きさや気密室２及び未充填の気密室８の設置数は調整できる。図２では気密室２、未充填の気密室８は階層構造で、津波の衝突の反対側にのみ未充填の気密室８を設置しているが、気密室２及び未充填の気密室８の設置数を増やすこと、単体自体の大きさによっては階層数を増やすことにより、気密室２の破損率の低下や表面積増加による安定性を高めることができる。尚、階層構造にする場合は、注入口３、排出口４、安全弁５、逆流防止弁６の設置場所は平面から側面に変更してもよく、また平面及び側面の両方に備えてもよい。また未充填の気密室の設置場所は、気密室２の後方側だけでなく気密室２の階層構造と同じように、気密室２の天頂部に変更してもよく、また気密室２の後方側及び気密室２の天頂部の両方に備えてもよい。
The size of the airtight chamber 2 and the unfilled airtight chamber 8 itself and the number of the airtight chambers 2 and the unfilled airtight chambers 8 can be adjusted according to the situation of the installation location. In FIG. 2, the hermetic chamber 2 and the unfilled hermetic chamber 8 have a hierarchical structure, and the unfilled hermetic chamber 8 is installed only on the opposite side of the tsunami collision. Increasing the number of installations and increasing the number of layers depending on the size of the single unit itself can increase the stability of the hermetic chamber 2 due to a decrease in the breakage rate and an increase in surface area. In addition, when setting it as a hierarchical structure, the installation place of the injection port 3, the discharge port 4, the safety valve 5, and the backflow prevention valve 6 may be changed from a plane to a side surface, and you may prepare for both a plane and a side surface. The installation location of the unfilled hermetic chamber may be changed not only to the rear side of the hermetic chamber 2 but also to the zenith portion of the hermetic chamber 2 in the same manner as the hierarchical structure of the hermetic chamber 2. It may be provided at both the side and the zenith of the hermetic chamber 2.
未充填気密室８は、排出用の排出口４と、気密室破損防止のための安全弁５と、連通させる気密室２の管路内に逆流防止弁６が設置されている。
The unfilled hermetic chamber 8 is provided with a discharge port 4 for discharge, a safety valve 5 for preventing damage to the hermetic chamber, and a backflow prevention valve 6 in the conduit of the hermetic chamber 2 to be communicated.
逆流防止弁６は、衝突による衝撃の吸収緩和及び反発力を得るためと、例えば衝撃により気密室２ａ、２ｄが破損しても被害を最小限に留める対策として設置されている。
The backflow prevention valve 6 is installed as a measure for minimizing damage even if the airtight chambers 2a and 2d are damaged due to impact, for example, in order to obtain shock absorption and repulsion due to impact.
ユニット式防潮壁１全体の安定性保持のため、天底部である気密室２ａ、２ｂ、２ｃ内に重量増加の一助として吸水性ポリマー１８が収納されている。
In order to maintain the stability of the entire unit type seawall 1, a water-absorbing polymer 18 is accommodated in the airtight chambers 2 a, 2 b, 2 c, which are the nadir parts, as an aid to increasing the weight.
ユニット式防潮壁１の少なくとも衝突側に剛性のある衝撃を吸収するための防御板７は、衝突の衝撃を吸収緩和するだけでなく、気密室２の破損防止の役割があるため、軽量で剛性のある防御板を使用するのが望ましい。
The protective plate 7 for absorbing the impact with rigidity at least on the collision side of the unit type tide barrier 1 not only absorbs and reduces the impact of the collision, but also serves to prevent the airtight chamber 2 from being damaged. It is desirable to use a protective plate with
ユニット式防潮壁１の固定手段９は、浮力対策、防水対策も兼ねており、磁気による脱着を主とした固定手段である。ユニット式防潮壁１を設置する土台には磁気反応の高い金属若しくは電磁石設備を、気密室の天底部にも磁気反応の高い金属若しくは電磁石設備１４を設置して、ユニット式防潮壁１同士の側面部分やユニット式防潮壁１とユニット式防潮壁１の少なくとも前面に設けられて衝撃を吸収するための防御板７には、磁気以外にも防水ファスナー、防水シール、面状ファスナーを使用し、ユニット式防潮壁１の膨張力を利用して脱着する。
The fixing means 9 for the unit-type tide barrier 1 also serves as a countermeasure for buoyancy and a countermeasure for waterproofing, and is a fixing means mainly for desorption by magnetism. The metal or electromagnet equipment with high magnetic reaction is installed on the base on which the unit type seawall 1 is installed, and the metal or electromagnet equipment 14 with high magnetic reaction is installed on the nadir of the hermetic chamber. In addition to magnetism, waterproof fasteners, waterproof seals, and surface fasteners are used for the protective plate 7 for absorbing shocks at the front of the part and the unit type seawall 1 and the unit type seawall 1. Detach using the expansion force of the tide barrier 1.
（００２８）以外の方法によるユニット式防潮壁１の固定手段９は、図４ではユニット式防潮壁１同様伸縮性があり強靭なネット又はシート１０とフック、アイボルト（ヒートン）１１設置の土台を備えている。今回の固定手段９は、（００２８）及び（００２９）の組み合わせをした図面になっているが、状況に応じて上記の単一又は組み合わせてもよい。尚、動作説明は（００２８）及び（００２９）を組み合わせた説明である。
