、海水の浄化が問題となってきている。[Prior art and problems to be solved by the invention] Attempts to clean the coastline by adding a seawater purification function to wave-breaking plates have been made.
A variety of things have been done. The simplest one is a pile of crushed stones piled up in the shape of an embankment. However, even if crushed stone is introduced into a place where sludge has already been deposited on the ocean floor, resulting in thick soft ground, it will simply be buried in the sludge layer and a large amount of crushed stone will be required, which is not efficient. Moreover, the quarry has the disadvantage that it is a permanent structure and cannot be moved. Recently, attempts have been made to construct artificial atolls in the sea and use them as offshore or underwater leisure bases with beaches, fishing spots, and various other leisure facilities. This is becoming a problem.

機能を備えた防潮堤となる。[Means for Solving the Problems 1] The present invention has been made to solve these problems. This was completed as a result of consideration. In other words, the characteristics of the structure are the base (1
) and a screen (2), the base g1 (1) is a sealed hollow body with a ballast material (4) sealed in the hollow part (3), and the screen (
2) is a box type with an open top made of multi-layered boards, with an outer wall (
Filling material (7) is roughly filled between the outer wall (5) and the inner partition wall (6), and seawater communication holes (
8) so that it can be installed even on underwater sludge as a wall embankment (10). In addition, a large number of these walls (10) were connected to form an artificial atoll surrounding a predetermined area of the ocean floor. The ballast material (4) enclosed within the base (1) may be crushed stone, crushed concrete, or other solid materials, but it is also preferable to have a structure that allows buoyancy to be adjusted by letting in and taking out seawater to accommodate changes in the foundation soil. . Various materials can be considered for the filler (7), but it is selected from suitable materials that create an environment necessary for microorganisms to live, such as shells, persimmon acid, crushed stone, pumice, coral chips, and in some cases plastic waste. An artificial atoll surrounded by a wall (lO) is not necessarily entirely formed by the wall dyke of the present invention, and a part thereof may be a bay or a conventional dyke. By laying a tray-shaped plate on part or all of the sea surface in an artificial atoll and covering it with clean masago, an artificial sandy beach is created on top of the sludge layer, which can be used to cultivate shellfish, shrimp, and crabs, as well as flounder and flounder. This also makes it possible to recreate a clean beach. [Operation] The base (1) is a sealed hollow body, and by adjusting the ballast material (4) sealed inside, the buoyancy of the wall bank can be adjusted to match the load suitable for the seabed ground. When the ballast material (4) is removed, a large buoyant force is generated, making it convenient to move. The inside of the screen is divided by partition walls (6), communication holes (8) form detours, and the filler material (7) forms a habitat for microorganisms, so seawater does not pass through due to the ebb and flow of the tide. Sometimes it becomes a wall that helps purify seawater. If such a wall embankment is bent to create an artificial atoll, it will become a seawall with a seawater purification function.

本発明の壁堤はその目的に適合したものといえる。[Example 1] A specific example of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a cross-sectional view of a model of a wall embankment, FIG. 2 is a front view, FIG. 3 is a perspective view of a plate laid on the seabed, and FIG. 4 is a plan view of a model of an artificial atoll. As is clear from Fig. 1.2, the wall embankment structure of the present invention consists of a planar ballast tank-like base (1) and a screen (2) standing upright thereon. Base ll1 (1) is a closed hollow body, and ballast material (4) is sealed in the hollow part (3), and the amount of ballast material (4) increases or decreases depending on the ground strength of the seabed. If the ground is a soft sludge layer, reduce the amount of ballast to prevent it from being buried in the sludge layer. The ballast material (4) is seawater in this case, and the material of the base (1) can be selected from concrete, FRP, steel plate, etc. depending on the ground condition, but here, it is made of FRP with a perforated iron plate as the core. There is. The basis of such a floating structure! @1t (1) with a screen (2) on top
) will be established. The screen (2) is an upwardly open box type made of multi-layered boards, and a filling material (7) is loosely filled between the outer wall (5) and the inner partition wall (6), and the outer wall (5) and the partition wall (6)
) has a seawater communication hole (8) in the base.
) and the screen (2) form a wall embankment (10). Depending on the material of the base (1), if the base (1) is made of FRP, the screen (
2) is also made of FRP. In this case, the inside of the screen (2) forms a three-layer passage with two partition walls (6), and the communication hole (8) is aligned between the high tide level (H) and the low tide level (L) as shown in the figure. Then, as shown in Figure 2, use vertical frame holes or continuous round holes. Upper opening part (9
) can also be closed with a lid after filling the inside with the filler (7). The filler (7) is preferably oysteric acid, and is loosely packed to allow good seawater flow. An air pump (
11) on the foundation and supplying air from the bottom of the screen (2) using an air supply pipe (12) is also effective. Making the insides of the outer wall (5) and the partition wall (6) also hollow will be effective in giving buoyancy to the wall embankment. Furthermore, it is possible to arbitrarily implement measures such as extending a pipe from the communication hole (8) that serves as a seawater passage on the open sea side and moving the seawater intake port offshore. As described above, the walls (10) are successively connected and enclosed to form an artificial atoll, an inland sea (14) facing the open sea (13) as shown in Figure 4, and the space of this inland sea (14) is used as a beach. It can be used as a leisure base such as a fishing spot, or as a fish farm. In that case, if sludge is buried on the seabed of the inland sea (14), it is best to spread tray-shaped plates (15) as shown in Figure 3 and create a clean sand layer (16) inside them. [Effects of the Invention] Due to the structure and operation described above, the wall dyke of the present invention can be stably installed on the seabed where a sludge layer is buried and serve as a breakwater, and at the same time, it has a seawater purification function. It is relatively easy to construct areas that can be used for beaches, fishponds, etc. by surrounding a large number of them, making them useful materials as part of marine development. In general, inland seas with calm waves have a lot of dirt on the seabed, so an embankment with a purifying effect is more ideal than a large wave barrier.1
It can be said that the wall embankment of the present invention is suitable for that purpose.
