Description

本発明は、港湾や海岸等に設置する防波堤に関するものである。   The present invention relates to a breakwater to be installed in a harbor or a coast.

一般に、わが国の防波堤は、経済的な観点から基礎マウンド上に函体（ケーソン）が複数配列され構成される混成堤が大半を占めている。混成堤の場合、函体及び基礎マウンドの安定性は、一般にうねりのような数秒から二十秒程度の周期を有する設計波浪に対して検討されてきた。一方、周期が数分から数十分となる周期の長い津波に対する波力の検討も行われてきたが、基礎マウンドを透過する波浪の影響は考慮されておらず、それが、混成堤の安定性に及ぼす影響は評価されていなかった。   In general, most of the breakwaters in Japan are composed of mixed levees composed of a plurality of boxes (caisons) arranged on the basic mound from an economic point of view. In the case of a hybrid bank, the stability of the box and foundation mound has been studied for design waves having a period of several seconds to 20 seconds, such as swells. On the other hand, wave forces have been studied for tsunamis with a long period of several minutes to several tens of minutes, but the influence of waves passing through the foundation mound has not been taken into account. The effects on aging were not evaluated.

ところが、津波が作用した場合の基礎マウンドの安定性については、該基礎マウンドを透過する波の影響が大きく、特に陸側の基礎マウンドは浸透した波（流れ）によって安定性が確保できなくなり、崩壊するような事例が実験や現地で確認されるようになった。この現象は、基礎マウンドの崩壊だけでなく、その上部に設置した各函体の安定性にも影響を及ぼし、最悪の場合、基礎マウンドからの崩落につながる危険性を誘発するものであった。   However, with regard to the stability of the foundation mound when a tsunami acts, the influence of the waves that pass through the foundation mound is significant. In particular, the foundation mound on the land side cannot be secured due to the permeated waves (flow), and collapses. Such cases have been confirmed in experiments and on-site. This phenomenon affected not only the collapse of the foundation mound, but also the stability of each box placed on top of it, and in the worst case, it induced a risk of collapse from the foundation mound.

このために、防波堤、すなわち混成堤の安定性を保持するためには、基礎マウンドの安定性を高める必要があり、津波のような周期の長い波の基礎マウンド内への浸透を防止し、基礎マウンドの崩壊を防ぐ必要がある。   For this reason, in order to maintain the stability of the breakwater, that is, the hybrid dike, it is necessary to increase the stability of the foundation mound, preventing the penetration of waves with a long period such as a tsunami into the foundation mound. It is necessary to prevent the mound from collapsing.

そこで、特許文献１には、ケーソンを設置して海洋構造物を構築するに際して、海底地盤の上部の堆積層に対して、セメント等の硬化材を混入し透水係数を小さくした不透水性地盤改良部を構築し、ケーソンを設置する部分に掘削溝部を構築し、そして、基礎石層を構築してから、アスファルト混合物を打設して基礎石層の石の間にも流動物を充満させて硬化させることが開示されている。   Therefore, in Patent Document 1, when a caisson is installed to construct an offshore structure, an impermeable ground improvement in which a hardening material such as cement is mixed into the upper sedimentary layer of the seabed ground to reduce the hydraulic conductivity. And then build the excavation groove in the part where the caisson is installed, and build the foundation stone layer, then place the asphalt mixture to fill the fluid between the stones of the foundation stone layer. Curing is disclosed.

しかしながら、特許文献１に係る管理型護岸の構築法では、作業が相当大掛かりなものになり採用することはできない。また、上述した混成堤には採用することができない。   However, in the construction method of the management type revetment according to Patent Document 1, the work becomes considerably large and cannot be adopted. In addition, it cannot be used for the above-mentioned hybrid bank.

本発明は、かかる点に鑑みてなされたものであり、津波や台風時等の基礎マウンドの安定性を確保すべく、津波や台風程度の周期を有する波に対しては、基礎マウンドの波の透過を抑制する防波堤を提供することを目的とする。 The present invention has been made in view of such points, and in order to ensure the stability of the foundation mound during a tsunami or a typhoon, the wave of the foundation mound is not applied to a wave having a period of the order of a tsunami or a typhoon . It aims at providing the breakwater which controls permeation .

本発明は、上記課題を解決するための手段として、請求項１に記載した発明は、基礎マウンド上に函体が複数配列されて構成される防波堤であって、前記基礎マウンドの内部で、その波浪方向略中央部の、その底面から上面に至る範囲にスラグ材が積層され、該スラグ材は、施工初期のマウンド本体の変形に追従することができ、その後、水と反応して膨張して、時間の経過と共に硬化して固化体となる性質を有することを特徴とするものである。
請求項２に記載した発明は、請求項１の発明において、前記スラグ材は、波浪方向に沿った断面において、断面台形状に積層されることを特徴とするものである。
請求項１及び２の発明では、基礎マウンドの内部で、その波浪方向略中央部の、その底面から上面に至る範囲にスラグ材が積層されるので、津波や台風程度の周期を有する波に対しては、基礎マウンド内の波が陸側に透過することを抑制することができる。すなわち、スラグ材においては、施工初期のマウンド本体の僅かな変形に追従することができ、その後、水と反応して膨張して、時間の経過と共に硬化して固化体となる性質を有するので、津波や台風程度の周期を有する波に対しては、基礎マウンド内の波の透過を長期間に亘って効果的に抑制することができる。スラグ材は、固化体となった後の透水係数が１０−２ｃｍ／ｓのオーダーとなるため、基礎マウンド全体としての透水係数を通常の１０−０ｃｍ／ｓのオーダーから２オーダー低下させることができるため、津波や台風程度の周期を有する波に対しては、十分な遮蔽効果を発揮することが可能になる。 As a means for solving the above-mentioned problems, the present invention is a breakwater comprising a plurality of boxes arranged on a foundation mound, the inside of the foundation mound, The slag material is laminated in the range from the bottom surface to the top surface in the substantially central part of the wave direction, the slag material can follow the deformation of the mound body at the initial stage of construction, and then reacts with water to expand. It is characterized by having the property of curing with time and becoming a solidified body .
According to a second aspect of the present invention, in the first aspect of the invention, the slag material is laminated in a trapezoidal cross section in a cross section along the wave direction.
In the first and second aspects of the invention, since the slag material is laminated in a range from the bottom surface to the top surface in the center portion of the wave direction in the foundation mound, the waves having a period of about a tsunami or a typhoon Thus, it is possible to prevent the waves in the foundation mound from penetrating to the land side . That is, in the slag material, it can follow the slight deformation of the mound main body at the initial stage of construction, and then expands by reacting with water, and since it has the property of hardening and solidifying over time, For waves having a period of a tsunami or typhoon, the transmission of waves in the foundation mound can be effectively suppressed over a long period of time. Since the slag material has a water permeability coefficient on the order of 10 −2 cm / s after becoming a solidified body, the water permeability coefficient of the foundation mound as a whole should be reduced by two orders from the normal order of 10 −0 cm / s. Therefore , a sufficient shielding effect can be exhibited against waves having a period of a tsunami or typhoon .

本発明の防波堤によれば、スラグ材の性質を利用することで、特に、津波等の発生時における、基礎マウンド内の波の透過を効果的に抑制することができ、基礎マウンド、ひいては、防波堤の安定性を確保することができる。 According to the breakwater of the present invention, by utilizing the properties of the slag material, it is possible to effectively suppress the transmission of waves in the foundation mound, especially when a tsunami occurs, and the foundation mound, and thus the breakwater Can be ensured.

以下、本発明を実施するための形態を図１〜図４に基づいて詳細に説明する。
なお、以下に、本発明の第１、第２及び第３の実施形態に係る防波堤１ａ、１ｂ、１ｃを説明するが、そのうち、第２及び第３の実施形態に係る防波堤１ｂ、１ｃが、特許請求の範囲に記載した発明に対応するものである。
本発明の第１の実施形態に係る防波堤１ａは、図１に示すように、波浪方向と直交する方向に延びる基礎マウンド２と、該基礎マウンド２上に複数配列される、ケーソンとしての函体３とから構成される。基礎マウンド２の陸側及び沖側の両方の法面及び法肩部（天端面において各函体３が配置される範囲を除く面）に沿って、該法面及び法肩部の全域を被覆するようにスラグ材１０が配置される。なお、各函体３内には、石材等の中詰め材が充填される。 Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to FIGS.
Hereinafter, the breakwaters 1a, 1b, and 1c according to the first, second, and third embodiments of the present invention will be described. Among them, the breakwaters 1b and 1c according to the second and third embodiments are described as follows. This corresponds to the invention described in the claims.
As shown in FIG. 1, a breakwater 1 a according to the first embodiment of the present invention includes a foundation mound 2 extending in a direction orthogonal to the wave direction, and a plurality of boxes as caissons arranged on the foundation mound 2. 3. Covers the entire area of the slope and shoulder along the slope and shoulder on both the land and the offshore side of the foundation mound 2 (the surface excluding the area where each box 3 is arranged on the top edge). The slag material 10 is arrange | positioned so that it may. Each box 3 is filled with a filling material such as stone.

スラグ材１０は、転炉系製鋼スラグ材が使用される。該転炉系製鋼スラグ材１０は、溶銑の精錬工程で生成される粒状の副産物である。転炉系製鋼スラグ材１０の主な化学成分は、石灰、二酸化ケイ素、酸化鉄等であり、特に、水硬性、膨張性等の性質を有し、水と反応する前においては外力によって僅かに変形する性質を有し、水と反応して膨張した後は、時間の経過に伴って硬化して固化体となる性質を有している。また、スラグ材１０は、透水性として、透水係数のオーダーから津波程度の周期を有する波に対しては、ほぼ流れを遮断して、一方、さらに周期の長い潮汐のような波に対しては十分に通水させる性質を有するものである。すなわち、防災対象となるような津波や台風時等の波に対しては遮水性を有し、環境上の潮汐のような波に対しては通水性を有することになる。
なお、本実施の形態では、スラグ材１０は、製鋼スラグ材の分類となる転炉系製鋼スラグ材が採用されているが、その他のスラグ材１０、例えば、溶融スラグ材の分類となる水砕スラグ材等を採用することもできる。 The slag material 10 is a converter steelmaking slag material. The converter steelmaking slag material 10 is a granular byproduct generated in the hot metal refining process. The main chemical components of the converter steelmaking slag material 10 are lime, silicon dioxide, iron oxide and the like, and particularly have properties such as hydraulic properties and expansibility, and slightly react with external force before reacting with water. It has the property of deforming and, after reacting with water and expanding, is cured with the passage of time and becomes a solidified product. In addition, the slag material 10 is substantially water-blocking for waves having a period of tsunami from the order of the permeability coefficient, while being permeable to water such as tides with a longer period. It has the property of allowing sufficient water flow. That is, it has water-imperviousness against waves such as tsunamis and typhoons that are subject to disaster prevention, and has water permeability to waves like tides on the environment.
In the present embodiment, the slag material 10 employs a converter steelmaking slag material that is classified as a steelmaking slag material. However, other slag materials 10, for example, a water granulated material that is classified as a molten slag material. A slag material etc. can also be adopted.

図２に示すように、多量のスラグ材１０が網状の袋体１１内に充填される。該袋体１１は、その材質として再生ポリエステル繊維が使用されており柔軟性に富む。袋体１１には、内部にスラグ材１０を充填した後吊り上げることが可能になるように吊りロープ（図示略）が備えられている。袋体１１の編み目ピッチは、内部のスラグ材１０が抜け出ない程度の適宜ピッチが採用される。また、袋体１１は、スラグ材１０により局所的に破断された場合でも、その箇所から破断が広がらない性質を有している。   As shown in FIG. 2, a large amount of slag material 10 is filled in a net-like bag body 11. The bag 11 is made of recycled polyester fiber as its material, and is highly flexible. The bag body 11 is provided with a suspension rope (not shown) so that the bag body 11 can be lifted after being filled with the slag material 10. As the stitch pitch of the bag 11, an appropriate pitch is employed so that the internal slag material 10 does not come out. Further, even when the bag body 11 is locally broken by the slag material 10, the bag body 11 has a property that the break does not spread from the portion.

基礎マウンド２は、図１に示すように、捨石４ａ等が積層される、断面台形状のマウンド本体４と、該マウンド本体４の法面及び法肩部（天端面）の全域を被覆するように配置される、多量のスラグ材１０が充填された複数の袋体１１と、スラグ材１０が充填された袋体１１を被覆するように配置される複数の被覆石５とから構成される。   As shown in FIG. 1, the base mound 2 covers the entire area of the mound body 4 having a trapezoidal cross section in which rubble 4a and the like are laminated, and the slope and shoulder (top end face) of the mound body 4. And a plurality of bag bodies 11 filled with a large amount of slag material 10 and a plurality of covering stones 5 arranged so as to cover the bag body 11 filled with slag material 10.

詳しくは、マウンド本体４の法面及び法肩部には、多量のスラグ材１０が充填された複数の袋体１１が、その法面及び法肩部に対して垂直方向に複数層に亘って配置されている（図１では２層）。スラグ材１０の層厚を略一定にする。その後、施工初期にマウンド本体４が僅かに変形した場合でも、スラグ材１０はマウンド本体４の僅かな変形に追従するようになる。その後、スラグ材１０は、水と反応することにより膨張するので、各スラグ材１０間の隙間が閉塞され、さらには、施工時にスラグ材１０が充填された各袋体１１間に僅かな隙間が存在していた場合でも、その隙間を埋めることが可能となる。その後、時間の経過と共にスラグ材１０が硬化して固化体となりその状態が維持されて、津波や台風時等の波に対しては、マウンド本体４内への波の浸透、ひいてはマウンド本体４内の波の透過を抑制することができる。
また、複数の被覆石５が、スラグ材１０が充填された複数の袋体１１を覆うように配置される。なお、これら被覆石５は、設置初期のスラグ材１０の安定性を確保するために必要に応じて設置するものである。 Specifically, a plurality of bags 11 filled with a large amount of slag material 10 are provided on the slope and the shoulder of the mound body 4 over a plurality of layers in a direction perpendicular to the slope and the shoulder. They are arranged (two layers in FIG. 1). The layer thickness of the slag material 10 is made substantially constant. Thereafter, even when the mound body 4 is slightly deformed in the initial stage of construction, the slag material 10 follows the slight deformation of the mound body 4. Thereafter, since the slag material 10 expands by reacting with water, the gaps between the slag materials 10 are closed, and furthermore, there is a slight gap between the bag bodies 11 filled with the slag material 10 during construction. Even if it exists, the gap can be filled. Thereafter, as time passes, the slag material 10 hardens and becomes a solidified body, and its state is maintained. With respect to waves such as during a tsunami or typhoon, the penetration of waves into the mound body 4, and thus within the mound body 4 Wave transmission can be suppressed.
Moreover, the some covering stone 5 is arrange | positioned so that the several bag body 11 with which the slag material 10 was filled may be covered. These covering stones 5 are installed as necessary in order to ensure the stability of the slag material 10 at the initial stage of installation.

なお、複数種類の大きさの袋体１１を用意し、これら各袋体１１に多量のスラグ材１０を充填しておき、マウンド本体４の法面及び法肩部に、複数種類の大きさの袋体１１を互い密着するように積み重ねるようにしてもよい。   A plurality of types of bag bodies 11 are prepared, and each bag body 11 is filled with a large amount of slag material 10, and a plurality of types of sizes are provided on the slope and shoulder of the mound body 4. You may make it stack the bag body 11 so that it may mutually contact | adhere.

以上説明したように、第１の実施形態に係る防波堤１ａでは、基礎マウンド２のマウンド本体４の法面及び法肩部の全域を被覆するように、多量のスラグ材１０を充填した複数の袋体１１を複数層積み重ねる。その際、施工初期においては、スラグ材１０は変形自在な性質を有するために、各函体３及び基礎マウンド２が僅かに変形した場合でも、各函体３及び基礎マウンド２の僅かな変形に追従することができる。その後は、スラグ材１０は水と反応することにより膨張するので、各スラグ材１０が互いに密着すると共に、津波や台風時等の波に対してはマウンド本体４内への波の浸透（マウンド本体４内の波の透過）を抑制すべく法面及び法肩部の全域を被覆することができる。さらに、その後は、時間の経過と共にスラグ材１０が硬化して固化体となりその状態が維持されるので、津波や台風時等の波に対しては、長期的に基礎マウンド２への波の浸透、ひいては基礎マウンド２内の波の透過を抑制することができる。 As described above, in the breakwater 1a according to the first embodiment, a plurality of bags filled with a large amount of the slag material 10 so as to cover the entire slope and shoulder area of the mound body 4 of the foundation mound 2. A plurality of layers of the body 11 are stacked. At that time, since the slag material 10 has a deformable property in the initial stage of construction, even if each box 3 and the foundation mound 2 are slightly deformed, the case 3 and the foundation mound 2 are slightly deformed. Can follow. After that, since the slag material 10 expands by reacting with water, the slag materials 10 are in close contact with each other, and the waves penetrate into the mound body 4 ( waves of the mound body during the tsunami, typhoon, etc.) The entire surface of the slope and shoulder can be covered so as to suppress the transmission of the wave within 4 . Furthermore, since the slag material 10 is hardened and becomes a solidified body with the passage of time thereafter, the state of the slag material 10 is maintained, so that the waves penetrate the foundation mound 2 in the long term against waves such as during a tsunami or typhoon. As a result, transmission of waves in the foundation mound 2 can be suppressed.

このように、津波や台風時等の波に対しては、スラグ材１０により基礎マウンド２への波の浸透（基礎マウンド２の波の透過）を抑制することができるので、津波等の発生時、特に、陸側の基礎マウンド２の崩壊を防止して、ひいては、防波堤１ａの安定性を確保することが可能になる。また、スラグ材１０は、上述したように、透水性として、津波や台風時等の波に対しては遮水性を有し、潮汐のような波に対しては通水性を有するので、基礎マウンド２を構成する部材として防災及び環境上最適である。 In this way, for tsunami and typhoon waves, the slag material 10 can suppress the penetration of waves into the foundation mound 2 (the transmission of waves in the foundation mound 2). In particular, it is possible to prevent the land-side foundation mound 2 from collapsing, and thus to ensure the stability of the breakwater 1a. Further, as described above, the slag material 10 has water permeability as a water permeable property against waves such as tsunamis and typhoons, and has a water permeability against waves such as tides. 2 is optimal for disaster prevention and environment.

また、第１の実施形態に係る防波堤１ａでは、多量のスラグ材１０を、柔軟性を有し吊り上げ用ロープが備えられる袋体１１に充填して作業するので、スラブ材１０の取り扱いが非常に容易になり、また、起重機船による運搬、水中への仮置きや潜水士船により据付が容易となる。   Further, in the breakwater 1a according to the first embodiment, since a large amount of the slag material 10 is filled in the bag body 11 that is flexible and provided with the lifting rope, the slab material 10 is very handled. In addition, it can be easily transported by a hoist ship, temporarily placed in water, or installed by a submarine ship.

なお、第１の実施形態に係る防波堤１ａでは、作業の簡素化を図るために、多量のスラグ材１０を袋体１１に充填し、その袋体１１をマウンド本体４の法面及び法肩部を被覆するように配置したが、多量のスラグ材１０を、直接、マウンド本体４の法面及び法肩部を被覆するように配置してもよい。   In the breakwater 1a according to the first embodiment, in order to simplify the work, a large amount of the slag material 10 is filled in the bag body 11, and the bag body 11 is used as the slope and the shoulder of the mound body 4. However, a large amount of the slag material 10 may be directly arranged to cover the slope and shoulder of the mound body 4.

次に、第２の実施形態に係る防波堤１ｂを図３に基づいて説明する。
第２の実施形態に係る防波堤１ｂを説明する際には、第１の実施形態に係る防波堤１ａとの相違点のみを説明する。
第２の実施形態に係る防波堤１ｂでは、その基礎マウンド２の内部において、波浪方向略中央部に、多量のスラグ材１０が充填された複数の袋体１１が、波浪方向断面台形状を呈するように積み重ねられ、その周りに捨石４ａ等が積層されて構成される。 Next, the breakwater 1b which concerns on 2nd Embodiment is demonstrated based on FIG.
When describing the breakwater 1b according to the second embodiment, only differences from the breakwater 1a according to the first embodiment will be described.
In the breakwater 1b according to the second embodiment, inside the foundation mound 2, a plurality of bags 11 filled with a large amount of slag material 10 in a substantially central portion in the wave direction so as to exhibit a wave direction cross-sectional trapezoidal shape. And rubble 4a and the like are stacked around it.

次に、第３の実施形態に係る防波堤１ｃを図４に基づいて説明する。
第３の実施形態に係る防波堤１ｃでは、第２の実施形態に係る防波堤１ｂの基礎マウンド２より高い基礎マウンド２を構築する場合、第２の実施形態に係る防波堤１ｂの基礎マウンド２を上方に複数段（図４では２段）に積み重ねるように構成している。
これら第２及び第３の実施形態に係る防波堤１ｂ、１ｃでは、第１の実施形態に係る防波堤１ａの効果に加えて、各スラグ材１０の安定性が増加するようになる。 Next, a breakwater 1c according to a third embodiment will be described with reference to FIG.
In the breakwater 1c according to the third embodiment, when the foundation mound 2 higher than the foundation mound 2 of the breakwater 1b according to the second embodiment is constructed, the foundation mound 2 of the breakwater 1b according to the second embodiment is directed upward. It is configured to be stacked in a plurality of stages (two stages in FIG. 4).
In the breakwaters 1b and 1c according to the second and third embodiments, in addition to the effect of the breakwater 1a according to the first embodiment, the stability of each slag material 10 is increased.

以上第１〜第３の実施形態に係る防波堤１ａ〜１ｃでは、基礎マウンド２の特定箇所にスラグ材１０を配置しているが、基礎マウンド２のほぼ全体をスラグ材１０を積層して構成してもよい。   As described above, in the breakwaters 1a to 1c according to the first to third embodiments, the slag material 10 is arranged at a specific location of the foundation mound 2, but the entire foundation mound 2 is configured by laminating the slag material 10. May be.
