Description

本発明は、消波堤,離岸堤,大水深離岸堤,人工リーフ等の消波構造物に使用する消波ブロックに関する。   The present invention relates to a wave breaking block used for a wave breaking structure such as a breakwater, a breakwater, a deep water breakwater, and an artificial reef.

従来、比較的小型で重量があまり大きくない消波ブロック(以降、ブロックと言う)を多数個設置して構築する消波堤,離岸堤,人工リーフ等の消波構造物は、ブロック同士を連結固定せずに設置すると、適宜な重なりとなり、重なり具合が十分でなく、ブロックが波動や水流によって損傷,沈下,散乱して、消波機能が低下するため、維持管理が必要であった。この抜本的対策としては、隣り合うブロックを相互に緊結する必要があり、水中での緊結作業を行なわなければならず、手間とコストが掛るものであった。   Conventionally, wave-breaking structures such as breakwaters, breakwaters, and artificial reefs, which are constructed by installing a number of relatively small and light-weight wave-breaking blocks (hereinafter referred to as blocks), are constructed by connecting blocks together. If it is installed without connecting and fixing, it will be appropriately overlapped, the degree of overlap will not be sufficient, and the blocks will be damaged, settled, or scattered by waves or water currents, and the wave-dissipating function will be reduced. As a drastic measure, it is necessary to tie adjacent blocks to each other, and it is necessary to carry out tying work in water, which is troublesome and costly.

このため、近年に於いては、ブロックに緊結具を用いずに、ブロック同士が一体化できるようにして、施工の簡素化やコスト低減を図ると共に、波動エネルギーの減衰効果の大きな消波構造が得られるブロックとして、特開2005−163362号や特開2006−125102号が提案されている。特開2005−163362号の構造は、前壁と後壁及び両壁を連結する斜壁からなる側断面の形状が略N型である消波ブロックであり、各壁に貫通穴を設け、海水の交換が容易に行われるための開口部が設けられたものである。これは順に設置することによって、後壁と前壁が重なり、設置と同時にブロック同士の連結が行われるものである。
又、特開2006−125102号のブロックの構造は、断面が台形であり、底面に台形上部を収容する嵌合凹部が形成され、上面から嵌合凹部に通ずる貫通穴が形成されている。また側面から嵌合凹部に通ずる貫通穴及び側面間に貫通穴が形成されている。
For this reason, in recent years, the blocks can be integrated with each other without using fasteners, so that the construction can be simplified and the cost can be reduced. JP-A-2005-163362 and JP-A-2006-125102 have been proposed as obtained blocks. The structure disclosed in Japanese Patent Application Laid-Open No. 2005-163362 is a wave-dissipating block having a substantially N-shaped side cross-section including a front wall, a rear wall, and a slope connecting the both walls. An opening is provided to facilitate the replacement of the device. In this arrangement, the rear wall and the front wall overlap with each other by being sequentially installed, and the blocks are connected to each other simultaneously with the installation.
Further, the structure of the block disclosed in JP-A-2006-125102 has a trapezoidal cross section, a fitting recess for accommodating the trapezoidal upper portion is formed on the bottom surface, and a through hole is formed from the upper surface to the fitting recess. Further, a through hole is formed from the side surface to the fitting recess, and a through hole is formed between the side surfaces.

しかしながら、特開2005−163362号のブロックを用いた消波構造物は、ブロックの前壁と他のブロックの後壁が重なり合っているが、消波構造物の最終端部や直角方向に対しては重なりがなく、自重で支えているだけであるため、端部から崩壊され易いものであった。又、特開2006−125102号のブロックを用いた消波構造物は、台形のブロックの上に他のブロックを乗せると、台形のブロックの上部と他のブロックの嵌合凹部が嵌合されて積み上げられるが、ブロック同士の水平方向の連結は、単に積重して設置され、自重で支えているだけであるため、上向き水流や水平方向の水流に対しては弱いものであった。
また特開2005−163362号と特開2006−125102号は、急峻な地形や想定を超える波浪に対応できる構造物としての安定性への配慮が十分とはいえない。従って、これらの消波構造物は、波浪による沈下や散乱等の抜本的解決には至っておらず、消波機能を維持するためのブロックの補強や散乱ブロックの回収といった定期的な維持管理が必要となる。
However, in the wave-dissipating structure using the block disclosed in JP-A-2005-163362, the front wall of the block and the rear wall of another block overlap each other. Since it did not overlap and was only supported by its own weight, it was easy to collapse from the end. In the wave-absorbing structure using the block disclosed in JP-A-2006-125102, when another block is put on the trapezoidal block, the upper part of the trapezoidal block and the fitting recess of the other block are fitted. Although the blocks are stacked, the horizontal connection between the blocks is merely stacked and installed, and is only supported by its own weight. Therefore, the blocks are weak against upward water flow and horizontal water flow.
Further, JP-A-2005-163362 and JP-A-2006-125102 do not sufficiently consider the stability as a structure capable of coping with steep terrain and unexpected waves. Therefore, these wave-dissipating structures have not yet completely resolved the sinking and scattering due to waves, and require regular maintenance such as reinforcement of blocks to maintain wave-dissipating functions and collection of scattering blocks. Becomes

Moreover, construction and maintenance are easy, and the total cost of construction and maintenance can be reduced.

請求項2のように四角形状で一対の左右壁(12)と、左右壁(12)間に設けた分流体(13)と、左右壁(12)の側面(12a)間で、しかも、その両側面(12a)の上下に設けた連結板(14)と、から少なくとも形成したブロック本体(1)と、連結板(14)の表面に設けると共に他のブロック本体(1)を水平方向で連結するための係止部材(3)と、左右壁(12)の上下に設けると共に他のブロック本体(1)を上下方向で連結するための連結部材(4)と、から少なくとも構成することにより、請求項1と同様な効果が得られる。   A pair of left and right walls (12) having a rectangular shape as defined in claim 2, a fluid distribution (13) provided between the left and right walls (12), and between the side surfaces (12a) of the left and right walls (12), and A block body (1) formed at least from connecting plates (14) provided above and below both side surfaces (12a), and another block body (1) provided on the surface of the connecting plate (14) and horizontally connected.

また本発明の消波ブロックの製造方法は、左右壁(12)を上下にして一体成型するか、連結板(14)や分流体(13)を先に成型させた後、各部分を組立て成型させると良い。この時、前記連結板(14)と左右壁(12)の接合は、コンクリート同士でも良いが、どちらか一方に図示しない鉄筋棒を突出させて設けておくと、コンクリート打設後の接合強度が高まる。尚、本発明品は鉄筋コンクリート製が好ましいが、素材はこれに限定されるものではない。   The method for manufacturing a wave-dissipating block according to the present invention may be such that the left and right walls (12) are vertically molded integrally, or the connecting plate (14) and the fluid distribution (13) are molded first, and then each part is assembled and molded. Good to let. At this time, the joint between the connecting plate (14) and the left and right walls (12) may be made of concrete. However, if a reinforcing bar (not shown) is provided so as to protrude on either one, the joint strength after concrete casting is reduced. Increase. The product of the present invention is preferably made of reinforced concrete, but the material is not limited to this.

図7はブロック本体(1)が水平方向で且つ千鳥状に連結される状態を上方から見た図であり、この図に基づいて水平方向の連結方法について説明する。先ず、図中に於いて、Aブロック本体(1)とBブロック本体(1)を横方向に所定の隙間を空け且つ後面を揃えて設置しておく。次に後方に連結する新たなDブロック本体(1)の前面を、Aブロック本体(1)とBブロック本体(1)の後面に半分接すように且つDブロック本体(1)の蟻ホゾ(31)をAブロック本体(1)の蟻溝(32)とBブロック本体(1)の蟻溝(32)に挿入しながら垂直に降下させて、前列のAブロック本体(1)とBブロック本体(1)の斜め後方に密着してDブロック本体(1)の設置を終える。

次に後方に新たに連結するEブロック本体(1)の前面を、Bブロック本体(1)とCブロック本体(1)の後面に半分接すように且つEブロック本体(1)の蟻ホゾ(31)をBブロック本体(1)の蟻溝(32)とCブロック本体(1)の蟻溝(32)に挿入しながら垂直に降下させて、Eブロック本体(1)の設置を終える。尚、この時のブロック本体(1)の設置順序は、上記の順序に限定されるものではない。
このように前記ブロック本体(1)同士の水平方向の連結は、蟻ホゾ(31)と蟻溝(32)により、ブロック本体(1)が千鳥状に連結されて前後方向及び横方向で一体化された結合体を形成できる。
尚、この時、図1に示すストッパー(2)又は図2に示す横方向用係止部材(5)を突設したブロック本体(1)を使用すると、横方向の所定の隙間が必然的に確保されて設置できるため、ブロック本体(1)を連結させる手順の自由度が増すと共に作業の効率が良いものとなる。
FIG. 7 is a view from above showing the state in which the block bodies (1) are connected in a staggered manner in the horizontal direction, and a method of connecting in the horizontal direction will be described based on this figure. First, in the figure, the A block main body (1) and the B block main body (1) are installed with a predetermined gap in the lateral direction and with their rear surfaces aligned. Next, the front surface of the new D block main body (1) connected rearward is in half contact with the rear surfaces of the A block main body (1) and the B block main body (1), and the dovetail ( 31) is vertically lowered while being inserted into the dovetail groove (32) of the A block body (1) and the dovetail groove (32) of the B block body (1), so that the A block body (1) and the B block body in the front row The installation of the D-block main body (1) is completed by closely attaching to the obliquely rear side of (1).
Next, the C block body (1) to be newly connected in the front row lateral direction is installed with a predetermined gap in the lateral direction and the rear surface aligned with the B block body (1).
Next, the front surface of the E block main body (1) newly connected rearward is in half contact with the rear surfaces of the B block main body (1) and the C block main body (1), and the dovetail ( 31) is inserted vertically into the dovetail groove (32) of the B block main body (1) and the dovetail groove (32) of the C block main body (1), and is vertically lowered to complete the installation of the E block main body (1). At this time, the installation order of the block body (1) is not limited to the above order.
As described above, the block bodies (1) are connected in the horizontal direction by the dovetails (31) and the dovetail groove (32), so that the block bodies (1) are connected in a staggered manner and integrated in the front-rear direction and the lateral direction. Conjugates can be formed.
At this time, if a block body (1) provided with a stopper (2) shown in FIG. 1 or a lateral locking member (5) shown in FIG. 2 is used, a predetermined lateral gap is inevitably formed. Since it can be secured and installed, the degree of freedom of the procedure for connecting the block main body (1) is increased and the work efficiency is improved.

図8はブロック本体(1)が水平方向で直線状に連結される状態を上方から見た図である。これは上記の千鳥状の場合と比べ、図中の如くAブロック本体(1)の後方に新たなブロック本体(1)を係止部材(3)によって所定個数連結させ、Bブロック本体(1)の後方に新たなブロック本体(1)を係止部材(3)によって所定個数連結させるが、Aブロック本体(1)の列とBブロック本体(1)の列は分離されている。このBブロック本体(1)を設置する際には、ストッパー(2)を突設したブロック本体(1)を使用して横方向の所定の隙間を確保して設置すると良い。   FIG. 8 is a view of a state where the block main bodies (1) are connected linearly in a horizontal direction as viewed from above. This is different from the above staggered case in that a predetermined number of new block bodies (1) are connected to the rear of the A block body (1) by the locking members (3) as shown in the figure, and the B block body (1) A predetermined number of new block bodies (1) are connected to the rear of the vehicle by the locking members (3), but the rows of the A block bodies (1) and the rows of the B block bodies (1) are separated. When installing the B block main body (1), it is preferable to use a block main body (1) in which a stopper (2) is protruded to secure a predetermined lateral gap.

次に図8に於いて、Aブロック本体(1)の列とBブロック本体(1)の列を上段のCブロック本体(1)の列により連結し、結合体を形成する方法について説明する。先ず始めにAブロック本体(1)の列の前から1番目と2番目のブロック本体(1)及びBブロック本体(1)の列の1番目と2番目のブロック本体(1)の隣り合う四隅部の上に、Cブロック本体(1)を垂直に降下させる。この時、図8に示すCブロック本体(1)の突起(43)を前記四隅部の内側に嵌め込むように降下させることによって、Aブロック本体(1)の列の1番目と2番目のブロック本体(1)及びBブロック本体(1)の列の1番目と2番目のブロック本体(1)の横方向の連結が行われるのである。
同様にして、新たなブロック本体(1)をCブロック本体(1)の後方に、順に嵌め合わせて、Aブロック本体(1)の列とBブロック本体(1)の列の上にCブロック本体(1)の列を嵌め合わせることで、Aブロック本体(1)の列とBブロック本体(1)の列の横方向を連結させる。同様に所定数横方向に設置させた下段の新たなブロック本体(1)の列は、各列間の上に新たなブロック本体(1)の列を設置することによって連結させる。
Next, referring to FIG. 8, a description will be given of a method of connecting a row of the A block main body (1) and a row of the B block main body (1) by a row of the upper C block main body (1) to form a combined body. First, four adjacent corners of the first and second block bodies (1) from the front of the row of the A block body (1) and the first and second block bodies (1) of the row of the B block body (1). Lower the C block body (1) vertically on the part. At this time, the first and second blocks in the row of the A block main body (1) are lowered by lowering the projections (43) of the C block main body (1) shown in FIG. 8 so as to fit inside the four corners. The horizontal connection of the first and second block bodies (1) in the row of the body (1) and the B block body (1) is performed.
Similarly, a new block body (1) is fitted in order behind the C block body (1), and the C block body is placed on the row of the A block body (1) and the row of the B block body (1). By fitting the rows of (1), the rows of the A block body (1) and the rows of the B block body (1) are connected in the horizontal direction. Similarly, a row of a new block body (1) in the lower row, which is provided in the horizontal direction by a predetermined number, is connected by installing a row of the new block body (1) above each row.

次に図9に基づいて横方向用係止部材(5)が設けられたブロック本体(1)同士の水平方向での前後左右の連結方法について説明する。この図9は、図8と同様にブロック本体(1)が水平方向で直線状に連結される状態を上方から示す図である。先ず始めに、設置したブロック本体(1)の後方へ順次係止部材(3)によって前後方向のブロック本体(1)同士を連結していく。
次に最前列の横方向に新たなブロック本体(1)を設置する際は、横方向用係止部材(5)を係止させる。最前列以外の新たなブロック本体(1)を設置する際は、横方向用係止部材(5)と係止部材(3)で係止させていく。
この時の横方向用係止部材(5)と前後方向の係止部材(3)を係止させる方法について説明する。図9、図10に於けるCブロック本体(1)を、Aブロック本体(1)の後方で、且つ、Bブロック本体(1)の横に設置させる場合、先ずCブロック本体(1)を垂直に下ろしながら、Bブロック本体(1)の側面に軽く当てる。
次に図10(a)のようにCブロック本体(1)の蟻ホゾ(31)の下端がBブロック本体(1)の上面近くまでCブロック本体(1)を下げ、図10(a)の図中の矢印のようにCブロック本体(1)の蟻ホゾ(31)が、Aブロック本体(1)の蟻溝(32)の真上に来るまで、Cブロック本体(1)を前に移動して蟻ホゾ(31)を蟻溝(32)の中に嵌め込んで下ろす。すると、図10(b)の2点鎖線の位置まで、Cブロック本体(1)が下がると、ホゾ部(51)が溝部(52)に自然に嵌り込み、Cブロック本体(1)の上面は、Aブロック本体(1)とBブロック本体(1)の上面が面一になり、Cブロック本体(1)の連結が完了するのである。このようにして新たなブロック本体(1)を係止部材(3)と横方向用係止部材(5)によって所定個数連結させる。
Next, a method of connecting the block main bodies (1) provided with the horizontal locking members (5) in the front, rear, left and right directions in the horizontal direction will be described with reference to FIG. FIG. 9 is a diagram showing, from above, a state in which the block main bodies (1) are connected linearly in the horizontal direction as in FIG. First, the block bodies (1) in the front-rear direction are sequentially connected to each other by a locking member (3) rearward of the installed block body (1).
Next, when a new block body (1) is installed in the lateral direction of the front row, the lateral locking member (5) is locked. When a new block body (1) other than the front row is installed, the block body (1) is locked by the horizontal locking member (5) and the locking member (3).
A method of locking the horizontal locking member (5) and the front-rear locking member (3) at this time will be described. When the C block main body (1) in FIGS. 9 and 10 is installed behind the A block main body (1) and beside the B block main body (1), first, the C block main body (1) is vertically set. And lightly touch the side of the B block body (1).
Next, as shown in FIG. 10 (a), the lower end of the dovetail (31) of the C block main body (1) is lowered so that the lower end of the C block main body (1) is close to the upper surface of the B block main body (1). Move the C block main body (1) forward until the dovetail (31) of the C block main body (1) is directly above the dovetail groove (32) of the A block main body (1) as indicated by an arrow in the figure. Then, insert the ant tenon (31) into the dovetail groove (32) and lower it. Then, when the C block body (1) is lowered to the position indicated by the two-dot chain line in FIG. 10B, the tenon portion (51) naturally fits into the groove (52), and the upper surface of the C block body (1) , A block main body (1) and B block main body (1) are flush with each other, and the connection of C block main body (1) is completed. Thus, a predetermined number of new block bodies (1) are connected by the locking member (3) and the horizontal locking member (5).

更に、図11はブロック本体(1)が上下方向で連結されて積み上げられる状態を横方向から見た図であり、この図に基づいて上下方向の連結方法について説明する。予めブロック本体(1)同士を係止部材(3)により、前後方向で連結した下段の1番目のブロック本体(1)の凹部(41)と2番目のブロック本体(1)の凹部(41)に上段の新たなブロック本体(1)の幅広な凹部(42)の両側部分(幅d)或いは上段の新たなブロック本体(1)の両前後壁(11)をそれぞれ挿入する。
この時、新たなブロック本体(1)の突起(43)は図8同様に、下段の1番目と2番目のブロック本体(1)の隣り合う四隅部の内側に嵌め込まれ連結が強化される。
このように、1段目の隣り合わせたブロック本体(1)の凹部(41)には、2段目のブロック本体(1)の幅広な凹部(42)の両側部分(幅d)或いは2段目のブロック本体(1)の両前後壁(11)が図中のようにそれぞれ挿入されて嵌め込まれるのである。この動作を水平方向に連結された1段目全体に渡って行えば、2段目のブロック本体(1)が上下方向並びに水平方向に連結されて積み上げられる。上記同様の要領でこの動作を所定段数になるまで積み上げれば、水平方向及び上下方向が連結され、一体化した強固な結合体を形成できるのである。
Further, FIG. 11 is a view of a state in which the block main bodies (1) are connected and stacked in the vertical direction as viewed from the lateral direction, and a vertical connecting method will be described based on this figure. The recesses (41) of the lower first block body (1) and the recesses (41) of the second block body (1) in which the block bodies (1) are connected in advance in the front-rear direction by the locking members (3). Then, both side portions (width d) of the wide concave portion (42) of the new upper block main body (1) or both front and rear walls (11) of the new upper block main body (1) are inserted.
At this time, the projections (43) of the new block body (1) are fitted inside the adjacent four corners of the first and second block bodies (1) in the lower stage as in FIG.
As described above, the concave portions (41) of the block main body (1) adjacent to the first stage have both sides (width d) of the wide concave portion (42) of the second stage block main body (1) or the second stage. Both front and rear walls (11) of the block body (1) are inserted and fitted as shown in the figure. When this operation is performed over the entire first stage connected in the horizontal direction, the block bodies (1) in the second stage are connected vertically and horizontally and stacked. By stacking this operation in the same manner as described above until a predetermined number of stages are reached, the horizontal direction and the vertical direction are connected, and an integrated strong joint can be formed.

このように本発明のブロック本体(1)は、各段の連結に於いて、係止部材(3)或いは係止部材(3)と横方向用係止部材(5)によって、ブロック本体(1)を前後方向又は横方向も同時に連結することが出来る。又、ブロック本体(1)を積み上げていく際は、下段の上にブロック本体(1)を乗せて連結部材(4)によって、下段に上段を連結して積み上げることが出来るのである。この結果、個々のブロック本体(1)は比較的軽量であっても、一体化され、大重量で強固な結合体を形成できるため、想定以上の大波浪にも安定性が確保され、効率的な消波機能を持続できる消波構造体を構築できる。
尚、これらの連結のための部材は応力が集中するため、損傷が受けにくいゴム製,鋼板等の部材による補強が望ましい。
As described above, the block main body (1) of the present invention is provided by the locking member (3) or the locking member (3) and the horizontal locking member (5) in the connection of each step. ) Can be simultaneously connected in the front-rear direction or the horizontal direction. When stacking the block main bodies (1), the block main body (1) can be put on the lower tier and the upper tier can be connected to the lower tier by the connecting member (4). As a result, even though the individual block bodies (1) are relatively light in weight, they can be integrated and form a heavy and strong combined body. It is possible to construct a wave-dissipating structure that can maintain a good wave-dissipating function.
Since the members for connection are concentrated in stress, it is desirable to reinforce the members with rubber, steel plate or the like which is not easily damaged.

図12は本発明品による消波構造体の作用を示す図であり、水流の動きに沿って波動力の減衰作用を説明する。波が押し寄せて来ると、前側の前後壁(11)に衝突し、波の一部を跳ね返すと共に、主水流は前後壁(11)の開口部(11a)からブロック本体(1)の内部に流れ込む。流れ込んだ主水流は、図中の実線矢印のように内部の中央で分流体(13)に衝突し、二等分流され減勢されながら後方の開口部(11a)に向って流れる。この時、上下段から浸入して来る流れも生じる。その後、主水流は、後方の開口部(11a)で合流して通過する。この時、水流の一部は分流し、上下段へ流出している。このように通過する際には、主水流の合流や上下段の水流が衝突し合うことにより、波動力が減勢される。   FIG. 12 is a diagram showing the operation of the wave-dissipating structure according to the present invention, and explains the wave power damping effect along the movement of the water flow. When the waves come in, the waves collide with the front and rear walls (11), bounce off part of the waves, and the main water flow flows into the block body (1) from the openings (11a) of the front and rear walls (11). . The main water flow that has flowed in collides with the dividing fluid (13) at the center of the inside as shown by the solid line arrow in the figure, and flows toward the rear opening (11a) while being divided into two equal parts and deenergized. At this time, a flow that enters from the upper and lower stages also occurs. After that, the main water flow joins and passes through the rear opening (11a). At this time, a part of the water flow is divided and flows to the upper and lower stages. When passing through in this way, the merging of the main water flows and the collision of the upper and lower water flows reduce the wave power.

同様に後方の開口部(11a)を通過した水流は、次の分流体(13)に衝突して上下に分かれて、次の開口部(11a)に向って流れる。このように連結された複数のブロック本体(1)の開口部(11a)から消波構造体内部に流れ込み、分流体(13)に衝突して上下に分かれ、後方の開口部(11a)で合流し通過していく。この水流の動きが最後端のブロック本体(1)まで繰返されるのである。更に消波構造体の内部に於いては、開口部(11a)から流れ込む水平方向の水流と、上下段から流れ込む上下方向の水流と、ブロック本体(1)の隙間を通過した他の方向から流れ込む水流等が衝突し合うため、波動力の減衰が助長される。
又、図12に示すとおり、逆方向水流に対しても同様な作用が得られる構造である。
Similarly, the water flow that has passed through the rear opening (11a) collides with the next fluid separation (13), is divided into upper and lower parts, and flows toward the next opening (11a). The fluid flows into the wave-absorbing structure from the openings (11a) of the plurality of block bodies (1) connected in this way, and collides with the fluid distribution (13) to be divided into upper and lower portions, and merges at the rear opening (11a). Then go through. This movement of the water flow is repeated up to the rearmost block body (1). Further, in the inside of the wave-absorbing structure, a horizontal water flow flowing from the opening (11a), a vertical water flow flowing from the upper and lower stages, and a flow from another direction passing through the gap of the block body (1). Since water streams collide with each other, attenuation of wave power is promoted.
In addition, as shown in FIG. 12, the structure has the same effect on the reverse water flow.

このように本発明のブロック本体(1)の第1の特徴は、水流が消波構造体を通過する際に、略上下対称形に設けられた変形しない空間の中で、前後壁(11),分流体(13)により、同勢の水流同士を均等に衝突させることで、消波構造体への衝突や負荷を小さく抑えながら、水流の滞留,分流,合流を繰返し、規則的に蛇行させることにより、その波浪エネルギーを減殺させる効率的な消波構造が形成されることである。
第2の特徴は、個々のブロック本体(1)は比較的軽量であっても、水平方向と上下方向の連結により一体化されることで、大重量で強固な結合体が形成できるため、想定以上の大波浪にも安定性が確保出来る消波構造体を海象条件の厳しい海岸や大水深に於いても建設コストを低減して構築できる。
第3の特徴は、ブロック本体(1)により消波構造体を構築する際に、かごマット上や格子枠等の脚上に構築することで、沈下や変状を抑制し、急峻な複雑な海底地形や軟質な地形であっても、散乱しない安定した消波構造体が構築できるので、消波機能や消波構造体の景観を長期的に確保し、ブロック本体(1)の補強投入や散乱ブロックの回収といった定期的な維持管理が不要となり、維持管理費用が軽減できることである。
As described above, the first feature of the block body (1) of the present invention is that when the water flow passes through the wave-dissipating structure, the front and rear walls (11) are provided in a substantially symmetrically provided undeformed space. , The flow of water (13) causes the same flow of water to collide with each other evenly, so that the water flow repeats stagnation, branching, and merging while keeping the collision and load on the wave-dissipating structure small, and meanders regularly. As a result, an efficient wave-breaking structure for reducing the wave energy is formed.
The second feature is that even though the individual block bodies (1) are relatively lightweight, they can be integrated by connecting in the horizontal direction and the vertical direction to form a heavy and strong combined body. The wave-dissipating structure capable of securing the stability against the above-mentioned large waves can be constructed at a reduced construction cost even on a shore where sea conditions are severe or at a great depth.
The third feature is that when the wave-absorbing structure is constructed by the block body (1), it is constructed on a car mat or on a leg such as a lattice frame, so that settlement and deformation are suppressed, and a steep complicated structure is obtained. A stable wave-dissipating structure that does not scatter even under the seabed or soft terrain can be constructed, so that the wave-dissipating function and the landscape of the wave-dissipating structure can be secured for a long time, Periodic maintenance such as collection of scattering blocks is not required, and maintenance costs can be reduced.
