Description

In the present invention, as shown in FIG. 3, a bridge 1 such as a metal wire or a teg is installed in accordance with the shape of the coral reef rock using a fixture 1 such as a nail or a pile struck against the reef rock. A transplanting method in which a plurality of corals 3 are bound and fixed to the bridge line 2 is a feature of the present invention. The transplanted coral attached to the bridge line will stick to the bridge line after a while and start to stick to the coral reef rock.
The feature of the present invention is that the physical strength of the coral reef rock that has been transplanted using the anchorage to the bridge line and the coral reef rock due to the growth of multiple transplanted corals is dramatically improved. The bridging line uses a material that is strong against tensile force.

  There are three features of the present invention. First, the present invention is an improvement in the physical resistance to waves when corals attached to a bridge line grow and stick to the bridge line and rock mass. Adjacent corals are connected via a bridge line, so when receiving physical force due to waves, the transplanted corals cooperate to resist physical force, reducing the dropout of transplanted corals. The

  Secondly, when the transplanted coral grows and integrates with the coral reef rock, that is, when the coral reef is turned into a coral reef, the bridge line remains in the limestone that is the skeleton of the coral. It exhibits a state like this. The coral killed skeleton plays the role of concrete. The bridge line is in a state that acts as a reinforcing bar. It becomes like a reinforced concrete structure where the limestone, the coral dead skeleton, resists compressive strength and the bridge line resists tensile strength. The physical strength against waves and the like is greatly improved.

Third, coral transplantation can be done efficiently. Once you have set up a bridge line with a fixture, you can transplant many corals just by tying the coral to the bridge line. In addition, transplantation of large coral can be done simply by tying it to the bridge line in the same way.
Placing nails and stakes to install bridge lines can be done easily even in the sea. A diver you are accustomed to can set up a bridge of several hundred meters in a day. It can be said that it is a suitable method for transplanting a large number of corals over a wide area because it can be transplanted simply by tying the corals to the bridge line.

  The present invention first provides a method that allows transplantation of large numbers of corals over a wide area. In the future, the bridge line used for transplantation will be used as a member that bears tensile strength against the physical energy of waves. There are no existing coral transplants aimed at physically strengthening coral reefs against waves.

  Coral reefs where corals grow are acting as natural breakwaters that protect tropical islands from typhoons and other waves. However, in recent years coral has been killed rapidly. When corals die, coral reefs are physically pierced or scraped by perforated shellfish or giant clams, and their strength decreases. Coral reefs can sometimes be severely destroyed when a huge wave from a typhoon rushes into a coral reef with a reduced strength. If a coral reef is healthy, it will not cause the coral reef to lose its strength because the part of the coral that grows is constantly supplied as a raw material for the reef. Conversely, when coral grows vigorously and there is a lot of raw material supply, the coral reef grows larger. In some cases, islands like Okinawa are created and become large structures like the Great Barrier Reef.

The present invention provides a method for enhancing the function of coral reefs as a breakwater and also provides a means for transplanting corals over a wide area. The transplanting method of the present invention is as simple as tying corals to the bridge line. The coral that has been tied up can be seen as if it were simply twisted and tied with aluminum wires. However, as the transplanted coral grows, it immediately begins to stick to the bridge line and to the coral reef rock. Transplanted corals are connected to each other by sticking to the bridge line, so it is possible to prevent the transplanted corals from falling off due to waves.
If the transplanted coral grows steadily after that, the part fixed to the bridge line and the coral reef rock will die due to insufficient light quantity and become a coral reef. This aspect of the incorporation of the bridge line inside the coral reef is similar to the physical aspect of reinforced concrete. The bridge wire plays the role of a reinforcing bar that handles the tensile strength, and the dead skeleton of the coral bears the compressive strength that the concrete takes on. Compared to coral reefs that have only a compressive strength that can only be made from coral killed skeletons, the coral reefs produced by the present invention have significantly increased resistance to physical energy such as waves.

  According to the present invention, the physical strength of coral reef rocks with a bridge line as a constituent of coral reef rocks is greatly improved. It is possible to artificially maintain and strengthen the function of coral reefs as breakwaters. Now that corals are dying and decreasing, it is considered important to create coral reefs that resist typhoons and other waves by physically strengthening coral reefs by transplanting corals using this method.

Coral reefs play an important role in protecting tropical islands from typhoons and other waves as breakwaters. However, as corals die, coral reefs are only destroyed by waves. Coral reefs have been maintained and strengthened in order for coral that normally grows abundantly to supply coral reefs with calcium carbonate, the raw material for coral reefs.
The present invention provides a method for maintaining and strengthening the function of a coral reef as a breakwater by coral transplantation. It is a transplantation method that constructs a coral reef that can be strongly resisted by the physical energy of waves by applying the concept of physical strength of a reinforced concrete structure to the coral reef.

  In the present invention, a plurality of piles are driven into a coral reef, and a bridge line of an arbitrary length is arranged so as to connect the piles and piles. Multiple bridges are attached to one bridge line and transplanted. As the transplanted coral grows, it sticks to the bridge line and the reef rock. If the transplanted coral grows smoothly after that, the bridge line will be taken into the coral reef as a constituent material of the coral reef as it grows.

  In the part of the coral reef derived from the transplanted coral according to the present invention, a bridge line will be left inside the coral reef rock. The compressive strength of calcium carbonate produced by the death of corals is high, but there is almost no tensile strength. A feature of the present invention is to maintain and strengthen the physical strength of the coral reef by carrying the strength against this tension with a bridge line.

Occasional loss of waves after transplantation of coral after transplantation is quite large, sometimes reaching over 70% of transplanted coral. The reason for this dropout is that underwater bonds are used for transplantation. Underwater bonds have a large difference in adhesion depending on the condition of the base of the place where they are to be enforced. If the coral reef rock at the transplant site is not cleaned enough and seaweed remains, the adhesive strength will be extremely reduced. If waves hit the transplanted coral with insufficient adhesion, it will fall off over time. However, in the past event-like coral transplantation, the reality is that underwater bonds are used in favor of the ease of handling and the image of bonding.
In the present invention, a plurality of corals are tied to one bridge line and transplanted. As long as the nails and stakes are firmly driven, the transplanted coral connected to the bridge line is unlikely to fall off due to the physical energy of the waves. The appearance right after transplanting is never good, but it never drops out.

  The present invention is a coral transplantation method in which coral transplantation is performed using a bridge line, and the coral reef bedrock is physically strengthened by a bridge line that is taken as a coral reef material in the future in which the transplanted coral becomes a coral reef material.

A 6cm long concrete nail is driven into the coral reef at a distance of about 1m. Cover the concrete nail with a plastic tube to prevent electric corrosion. An aluminum wire with a diameter of 3mm is tightly wound around the concrete nail that has been driven in and stretched along the surface of the coral reef. Coral transplantation is performed by attaching and fixing 10 cm of coral fragments to this stretched bridge wire with an aluminum wire with a diameter of 1 mm. The coral fragments to be transplanted are tied so that a part touches the coral reef.
In about a month, coral fragments grow and begin to stick to the bridge. After further growth and about 3 months, the transplanted coral fragments begin to stick to the coral reef from the part touching the coral reef.
After a year, the transplanted coral will firmly adhere to the bridge and the coral reef. The transplanted corals are connected to each other via a bridge line.
After a few years, corals have grown considerably to the surface. The part that takes in the bridge line will be killed due to insufficient light quantity. This dead part becomes a coral reef. This coral reef is still covered with the aluminum bridge used for coral transplantation. The bridge line taken inside the coral reef with this tensile strength enhances the resistance to physical forces against the coral reef waves.

A 6cm long concrete nail is driven into the coral reef at a distance of about 1m. Cover the concrete nail with a plastic tube to prevent electric corrosion. An aluminum wire with a diameter of 3mm is tightly wound around the concrete nail that has been driven in and stretched along the surface of the coral reef. A bridge line will be installed in the same way about 20cm apart on both sides of this bridge line. Three bridge lines are arranged in parallel.
A coral with multiple branches that have grown drooping for about a year and grown to about 15 cm will be transplanted to the middle bridge. Transplantation is performed using a 1 mm fixing aluminum wire. Place the branch coral to be transplanted on the bridge line. Wrap the end of the fixing aluminum wire about 5 cm away from the coral to be transplanted to the bridge line. Wrap the other end of this fixing aluminum wire around the branch of the coral to be transplanted. The position of the branch to wrap is the branch on the bridge line. The coral branch on the opposite side of the fixed branch is also fixed to the bridge line with a fixing aluminum wire. Next, fix the coral branch to the bridge line installed in parallel at the position close to the coral branch with the fixing aluminum wire. The transplanted coral branch is fixed in the same way using the parallel bridge line on the opposite side. The transplantation coral is fixed in the shape of a cross with four fixing aluminum wires.
This transplant method is used when you want to make the transplanted place available for sightseeing in a short period of time. As the transplanted coral grows, the aluminum wire of the bridge line is finally taken into the coral reef, so the physical strength of the coral reef is improved.

In the present invention, coral reefs are physically strengthened by coral transplantation. In recent years, the supply of coral reef materials has been cut off due to the death of corals, making it difficult to maintain the function of the coral reef as a breakwater.
Coral transplantation according to the present invention can maintain and strengthen the function of the coral reef as a breakwater. As sea level rises due to global warming in the future, coral reef function as a breakwater will be lost. The present invention prevents the transplanted coral from falling off and increases the supply of coral skeleton as a coral reef material. At the same time, the physical strength of the coral reef can be strengthened. Coral reefs can be expected to increase if this method is used to transplant corals that can catch up with sea level rise due to global warming. It may be possible to save a sinking island country.

In the present invention, coral transplantation is performed using a bridge line. Work such as driving nails and stakes into coral reefs and installing bridge lines can be done efficiently even underwater. It is easy to install a bridge line over a wide area. The present invention is a suitable method for transplanting corals over a wide range.
It is a coral transplantation method that can be applied to hundreds of kilos of leaves.
