【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、潜堤の構築用ユニットに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a unit for constructing a submerged dike.
〔従来技術および解決すべき課題〕 従来より、離岸堤や潜堤は海岸などの浸食対策手段とし
て広範に使用されているが、離岸堤は海岸から少し離れ
た海面上に堤体が突出する構造であることから景観上好

堤が積極的に採用されるようになっている。[Prior art and problems to be solved] Conventionally, breakwaters and submerged breakwaters have been widely used as measures against erosion on coasts, etc., but breakwaters project on the surface of the sea a little away from the coast. It has been pointed out that it is not preferable for the landscape because of its structure, and in recent years, submerged dikes that can secure a calm sea area without obstructing the landscape by setting a dike below the sea surface are being actively adopted. It has become.

れていた。By the way, this submerged dike is usually constructed by combining multiple layers of wave-dissipating root blocks on a mound formed of rubble, but not only is the installation work on the sea complicated, but the number of blocks used is also large. Therefore, the construction cost is high, and even when it is considered as a fish reef as a means for growing seafood, various problems have been pointed out that it is not so effective because the porosity is small.

空隙率の増大化を図れるようにしたものである。[Means for Solving the Problems] In this invention, therefore, a pair of inclined members having vertical leg portions extending at the front and rear ends thereof are separated by a predetermined distance, the rear end portions thereof are connected by a top horizontal member, and the front leg portions are horizontally aligned at the bottom. A building unit is formed by connecting the members with each other, and further constructing a middle-level horizontal member between the tilting members, and preparing a large number of this building unit to deviate in the direction orthogonal to the tilting direction in a zigzag pattern. By further stacking, a submerged dike is constructed to facilitate the installation work and increase the porosity by reducing the number of blocks used.

As a result, the stability of the entire submerged dike can be improved.In addition, the constructed submerged dike will have the cross-section roughness due to the top horizontal member of each unit and the wart roughness due to the top end of each inclined member. The wave effect is also improved.

る。In the construction unit according to the present invention, the embankment can be constructed simply by shifting a large number of units in the direction orthogonal to the inclination direction and further stacking them in a staggered manner, so that the installation work is easy, and each unit itself has a frame shape. Since it is formed in a large area, it has a large porosity and is suitable for use as a fish reef.
次に本考案に係る潜堤構築用ユニットの好適な実施例に
つき添付図面を参照しながら以下詳細に説明する。A preferred embodiment of the submerged embankment building unit according to the present invention will now be described in detail with reference to the accompanying drawings.

連結するとともに各前脚部14、14を底部水平部材22で連
結し、さらに各傾斜部材12、12間に中位部水平部材24を
架設することにより構成する。Referring to FIG. 1, a submerged embankment building unit 10 according to the present invention.
Is formed into a frame shape using reinforced concrete or the like as a material, and specifically, the vertical leg portions 14 and 16 are respectively extended to the front and rear end portions of the pair of inclined members 12 and 12 which are separated by a predetermined distance. The vertical leg portions 14, 16 are connected by a horizontal connecting member 18, and the vicinity of the tops of the inclined members 12, 12 are connected by a top horizontal member 20 and the front leg portions 14, 14 are connected by a bottom horizontal member 22, Further, a middle-level horizontal member 24 is installed between the inclined members 12, 12.
なお、前記頂部水平部材20の下面は傾斜状に形成されて

定されている。Further, the distance A in the front-rear direction between the bottom horizontal member 22 and the middle horizontal member 24 is set to be substantially the same as the width B of the rear leg 16.
次にこのように構成されるユニット10を使用して潜堤を
構築する場合につき説明すると、まず、捨て石などによ

ニット10aの後脚部16、16が陸側になるように順次隣接
設置しておく。この状態あるいは潜堤を構築した状態に
おいて各ユニット10の底部水平部材22は捨石マウンド28
の飛散防止機能を有している。Next, the case of constructing a submerged embankment using the unit 10 configured as described above will be described. First, the rear leg portion 16 of the unit 10a is formed along the embankment forming direction on the mound 28 previously formed by discarding stones. , 16 are installed adjacent to each other so that 16 is on the land side. In this state or in the state where the submerged dike is constructed, the bottom horizontal member 22 of each unit 10 is a rubble mound 28.
Has a scattering prevention function.
次にこれら隣接する各ユニット10aの底部水平部材22と
中位部水平部材24との離間部に別体のユニット10bをそ
の傾斜方向と直交する方向に1/2づつずらした状態で後
脚部16、16を嵌入して一層積とする（第２図参照）。Next, the rear leg portion in the state where the separate unit 10b is shifted by 1/2 in the direction orthogonal to the inclination direction at the space between the bottom horizontal member 22 and the middle horizontal member 24 of each of the adjacent units 10a. Insert 16 and 16 into a single layer (see Fig. 2).
この場合、沖側に位置するユニット10bの後脚部16は陸
側に位置するユニット10aの中位部水平部材24の前面と
底部水平部材22の後面とで保持されるとともに陸側に位

下面および横水平部材26に夫々当接するので相互にしっ
かり噛み合い、潜堤全体としての安定性が保持できるこ
とになる（第３図参照）。In this case, the rear legs 16 of the unit 10b located on the offshore side are held by the front surface of the middle horizontal member 24 of the unit 10a located on the land side and the rear surface of the bottom horizontal member 22 and located on the land side. The inclined members 12 and 12 of the unit 10a and the front surface of the front leg portion 14 abut on the inclined lower surface and the horizontal horizontal member 26 of the top horizontal member 20 of the unit 10b located on the offshore side, respectively, so that they firmly mesh with each other, and The stability can be maintained (see FIG. 3).
また、特に図示していないが、陸側に位置するユニット
10aの後脚部16、16間を蓋体などにより適宜閉塞すれ
ば、養浜砂の土留めとしても機能させることができ好適
である。Although not shown in the figure, the unit is located on the land side.
If the space between the rear legs 16 of the 10a is appropriately closed by a lid or the like, it can also function as a soil retaining for beach nourishment sand, which is preferable.
さらに、海面からマウンド28までの水深が深い場合など

に嵌合する構成を採用すれば良い。Further, when the water depth from the sea surface to the mound 28 is deep, it is sufficient to use a unit in which the legs 14 and 16 are set to be long as shown in Fig. 4, and it is necessary to set the crown width W of the dam body large. If there is any, as shown in FIG. 5, it is advisable to adopt a configuration in which the separate units 10c are sequentially fitted in a zigzag manner to the units 10b located on the offshore side.
このようにして構築される潜堤では各ユニットがしっか
りと噛み合い全体が一体化されしかも傾斜部材を介して

させることができる。In the submerged dike constructed in this way, each unit is firmly meshed and the whole is integrated, and the wave force of the incident wave can be converted to the vertical downward direction through the tilting member, so it is excellent in stability and also the air gap. Since a large number of frame-shaped units can be stacked and constructed, the required number is small and workability and economic efficiency are high, and the top and side surfaces are open to form a complicated space inside, and the fish reef effect is also large. Since the top horizontal member and the top end of each inclined member of each unit form a cross roughness and a warp roughness for an incident wave, the wave-dissipating effect can be increased.

利点を有しその実用的効果は極めて大きい。As described above, the construction unit according to the present invention can be used in a small number because the submerged dike can be constructed with more layers, and is extremely advantageous from the conventional point of view in terms of workability and economic efficiency due to shortened sea work. Moreover, the scale of the entire dam body, such as the height of the dam and the width of the dam, can be easily adjusted according to the water depth and the required wave height to be transmitted. In addition, since it has a frame shape with a large porosity, it has excellent stability, and since the opening is also large, sunlight penetrates into the inside of the levee body without blocking the exchange of water inside and outside the levee, and it is also suitable for use as a fish reef. It has various advantages such as being able to be used, and its practical effect is extremely large.
