Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to underwater floating structures, and in particular, allows floating breakwaters, floating breakwaters, floating fishing reefs, pollution prevention membranes, etc. to be installed in the ocean. Regarding underwater floating structures.

Conventional technology In the ocean, there are underwater structures such as fishing reefs and dredging for aquaculture.
Floating bodies are installed like underwater structures to prevent pollution from spreading in land reclamation, etc., and necessary parts such as hanging members for fishing reefs and pollution prevention membrane members are attached to these depending on the purpose. ing.

However, the floating bodies used in these underwater structures are all made of foamed plastic materials;
Their useful life is limited to 2 years, while landfill work can last 5 to 10 years. Disposal after use is by incineration, but corrosion and toxic gases are generated during this process. Welding cannot be used when attaching parts, making field workability and repairability poor. When the sea becomes rough due to a typhoon, you must evacuate to calm water to avoid being washed away. Since the connection is made by connecting wires or chains, the floating body may be rotated by waves, etc., and the anti-pollution membrane may be rolled up, and the connected parts of the floating body may be subjected to stress due to twisting, etc., making it easy to break. When mooring to an anchor with a chain or the like, there are problems in that the chain cannot be attached anywhere on the floating body by means of a wheel such as welding, and is therefore limited to the connecting parts.

Furthermore, floating objects made of foamed plastic materials may be moved by the waves in rough waves and cannot be kept in a fixed position. However, as fishing grounds have become narrower in recent years,
Aquaculture is gradually increasing. However, this aquaculture can only be carried out in bay areas with calm waves, so the development of aquaculture is also limited by the location of the farms. If it were possible to artificially create a so-called calm area by blocking or dissipating waves even in the rough open ocean, it would be possible to set up so-called sea farms at will, which would be a breakthrough for the fishing industry. Instead, it can now be used as a beach, and it is hoped that this will become a reality.

Problems to be Solved by the Invention As mentioned above, since the floating bodies of conventional underwater structures such as floating fishing reefs and anti-pollution membranes were made of plastic, there are problems with their service life, disposal, weather changes, etc. There were problems with evacuation during the event, workability on site, etc., and there was also a problem that it could not be used for wave prevention or wave dissipation because it was lightweight, and there was a desire to improve these problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention is characterized by having a structure in which floating bodies whose peripheries are covered with iron material and are hollow are connected via circular flexible cushioning materials. The purpose of the present invention is to provide an underwater floating structure.

It also has a structure in which a floating body whose periphery is covered with iron material and is hollow is connected via a circular flexible cushioning material, and a circular flexible cushioning material is fitted on the outside of the floating body. The purpose of the present invention is to provide an underwater floating structure.

Since a floating body made of working iron is provided, it is durable, has a large weight, does not easily move due to waves, etc., and is easy to weld.

Example Next, one embodiment of the present invention will be described.

Figure 1 shows an underwater fence member that is a component of a pollution prevention membrane. 1 is an iron floating body, 2 is a flapper made of a sheet and a net, and this underwater fence member is connected in large numbers under the sea. used. Reference numeral 3 in FIG. 2 denotes the connecting portion, and the U-shaped connecting pieces 3a, 3a welded to the ends of the floating body 1.1 are connected to the chains, wires, etc. shown in FIG.
A reinforcing tire 3d as a circular flexible cushioning material consisting of a tire 3c with a core material 3b such as a ring inside is inserted through bolts 3f at both ends of the U-shaped portion 3e and tightened with nuts 3g. It is constructed by connecting and fixing the tires at both ends to the floating body 1.1 with bolts and nuts. Note that the last connection between tires can be performed by forcibly opening the gap between them.

Further, the reinforced tire may be constructed by attaching the core material to the side surface of the tire 3C.

, - Y, which are connected together form a fence in the sea, and when surrounded by this fence, the polluted water generated therein is prevented from dispersing to the outside world.

Further, a fence as shown in FIG. 4 may be constructed.

That is, the attachment parts 3j, 3 are welded to both sides of the floating body 1.
j... is provided, and this is moored to an anchor 6.6゛, which is an iron pipe filled with sand, by a connecting body 5.5... As shown in FIG. 5, the connecting body 5 has the above-mentioned reinforced tires 3d and 3d connected to the floating body 1 and the anchor 6.6" at the attachment point, and these reinforced tires are connected by a chain 7. At this time, if the sheet 8.8 is pasted on the lower side of the connecting body 5.5 and the flapper 2 is the sheet 2' only at the upper part of the water depth, the turbidity of the seabed will be reduced by the sheet 8.8'. The water settles in the stagnation area in between, while the turbidity above is blocked by the sheet 2°, allowing only relatively clean water to flow through the middle part where the flow resistance is small.At this time, even if the sheet 2 is rolled up, the water on both sides It does not hit the connecting body and roll up, which prevents contaminated water from passing through.

In the above example, the stagnation area was created by providing the connecting body in a V-shape, but as shown in Figure 6, it is also possible to use a sheet 8 on the bottom, a fine net 9 on the top, and a coarse net 10 in the middle. good.

As shown in FIGS. 7(a) and 7(b), the connecting parts of the floating bodies of the above-mentioned underwater fence member are formed by spaced apart half-moon-shaped connecting pieces 1a, Ib, and IC at both ends of the floating body 1 (one end shown in the figure). The bolts 1d can be inserted into the tips of these and tightened with the nuts 1e. And these floating bodies 1
．． 1 adjacent to each other, reinforced tires 3d, 3d similar to the above
between the connecting pieces 1a and 1b of each floating body, connecting piece 1
b. These reinforced tires are placed between the ICs, and are prevented from being pulled out from the connecting pieces by the above-mentioned Pol) ld and oak He on the connecting pieces of each floating body. Thereafter, a partition member 1f made of a rubber material may be attached to each reinforced tire at an intermediate position using appropriate means such as screws to buffer the impact of a collision between connecting pieces of adjacent floating bodies.

Although the pollution prevention device has been described above, the floating fishing reef frame may be constructed by connecting the floating bodies 1 and mooring them to the seabed by the connecting bodies. When tire buffer floating bodies 11 are fitted with tires lla, lla, etc., which are similar to the tire 3C but are usually larger than the tire 3C and are circular flexible cushioning materials, and are arranged vertically and horizontally in a grid pattern, a breakwater, wave dissipating structure is created. It can also be used as a bank. In this way, collisions between floating bodies can be buffered. In this case, the connecting portion of the machine may also be as shown in FIG.

In addition, as shown in Figure 9, by connecting tire buffer floating bodies 11 and 11 in parallel, their stability at sea increases and they can be used as a stage for offshore work, as well as installing indicator lights for safe navigation of ships. It can also be used as a pedestal.

In addition, as shown in FIG. 10, the above-mentioned connecting body is constructed by connecting reinforced tires 3d with chains or wide metal pieces (to prevent rotation of the tires), and an auxiliary floating body 12.12 is placed in the middle.
may be provided.

As described in detail, according to the present invention, the floating body of the underwater floating structure is made of iron material, so it has a long service life, can be used without replacement during a long construction period, and can be easily welded. It is easy to work on site, its large weight allows it to be held in a relatively fixed position even when the waves get rough due to typhoons, etc., the steel can be reused even when discarded, and it is easy to weld, making it easy to attach mooring connections. It can bring about excellent effects such as being easy to implement, and as a result, it can provide much better pollution prevention devices and fishing reefs than conventional ones, and it is also possible to install floating breakwaters and breakwaters, which were previously considered difficult. This makes it possible to create calm areas in the rough seas, expand aquaculture fishing grounds, make marine authorities possible, and expand the area of sea that can be used as beaches.

In addition, by using old tires for the connecting portion of the floating body and the circular flexible cushioning material that is used by fitting the floating body, it is possible to effectively utilize resources.
