Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the safety and disaster prevention of a floating structure. The characteristics of a floating structure include an earthquake and a ground like structures on the ground. It is not affected by the bearing capacity of the ground, but there is the danger of sinking due to waves or typhoons, collision of drifting objects such as large ships with broken marine lines, oil spill of large tankers, burning, and attacks by submarines and torpedoes Furthermore, there is a serious problem in the safety and disaster prevention of the floating structure because it is directly exposed to external enemies such as sharks and intruders. [0003] The present invention provides a floating structure that is free from ground disasters such as floods, sediment flows, landslides, earthquakes, land subsidence, etc. "Purification system of water area" patent application 56-148107 and "Tsunami protection system" to protect marine enemy such as spill, fire, torpedo, submarine, shark etc.
While removing the disadvantages of the floating structure while sharing with the system of Japanese Patent Application No. 58-189672, etc., as a floating structure that is both environmentally safe and environmentally safe, establish the most safe and disaster-preventive location throughout the sea and land on the earth. We are trying to secure it. [0004] Conventional floating structures are directly exposed to water bodies such as natural seas or are protected by breakwaters having openings.
In many cases, the waves bypassed the breakwater and were affected by the above waves. Means for Solving the Problems The surrounding water area surrounded by the embankment structure is collectively referred to as “the surroundings of the water area”. The water area surrounded by the breakwaters having multiple voids is a calm water area, and such a floating structure is installed in the calm water area. [Action] By constructing the interior of a water area and installing a floating structure in such a calm water area, waves, storm surges, tsunamis, collision of large drifts, oil spills, flames, torpedoes, submarines, It is possible to defend against foreign enemies such as sharks. (Defense of Waves) Waves rushing from the open sea can be classified into ripples, wind waves, swells, and still vibrations, tsunamis, storm surges, tides, and the like, depending on the period. By being surrounded by a breakwater having multiple voids, short-period ripples, wind waves, and undulations are waves that are easily broken, and are broken by the breakwater to extinguish the energy of waves. In addition, long-period static vibrations, tsunamis, storm surges, tides, etc. were gradually penetrated using the gaps in the embankment body, and the inner water level was raised over time, so that they were surrounded by breakwaters with multiple gaps Maintain the calmness of the interior of the water. Furthermore, for swells, static vibrations, and tsunamis with relatively short periods, the ratio (h / H) of the water depth h at the front of the embankment to the wave height H of the offshore waves is 2
It is also possible to reflect light by holding it more deeply. ("Tsunami Protection System" Patent Publication No. 60-80611) [0008] The collision of large floating objects such as large vessels with broken marine lines and rudder wreckage during a typhoon on floating structures has become a major problem. I have. By surrounding the floating structure by the breakwater having multiple voids, it is possible to prevent collision or contact between the floating structure and the large drifting object. [0009] Drifting oil can flow out through the ground or a river on the ground, or outflow due to collision or explosion of a large tanker, and drifts under the influence of tide or wind. It exists in a state of floating as a liquid or oil ball, a state of floating in water, or a state of precipitation. Oil has a property of easily adhering to the surface of a thing, and a breaking wall having many voids has a large surface area, adheres to the surface of the embankment material, and forms a strong barrier by the adhesive action of the oil. Moreover, natural purification is promoted by the biological action of the breakwater having multiple voids. Further, the oil ball is also protected by the filtering action of the breakwater having multiple voids. The safety of the floating structure is maintained by the protection effect of the breakwater having multi-voids, which is not subjected to fire or fire by an impact of a large vessel or an oil tanker explosion. [00011] Floating structures may sink due to torpedoes or submarine attacks. It is possible to prevent direct attack from underwater by enclosing the structure with the breakwater with multiple cavities, and the safety is maintained for a while. Further, it is possible to prevent an intruder by a protective action by surrounding a floating structure by an intruder such as a shark and a floating structure having multiple voids in order to maintain safety around the floating structure. It is. [00013] In purifying the environment of the water quality around the floating structure, the water inside and outside the water area surrounded by the breakwater having multiple voids is cleaned by the operation of the "water area purification system" Patent Application No. 56-148107. An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a plan view of the present invention, and FIG. 2 is a cross-sectional view of the present invention. As shown in FIG. It is a calming water area 3 in which the floating structure 2 is installed. The embankment structure 1 is a known breakwater in which materials such as conventional discarded stones and concrete blocks are stacked on the seabed ground 6. Originally, a floating structure has a large characteristic that is not affected by an earthquake or a ground support force, unlike a structure on land, but on the other hand, a wave or a drifting object collides. There is a drawback that it is easily affected by direct exposure to foreign enemies in the ocean. However, by installing the floating structure 2 in the calm water 3 surrounded by the breakwater 1 having multiple voids,
This has the effect of removing defects of the floating structure. As a wave protection effect, by enclosing with a breakwater 1 having multiple voids, ripples, wind waves, and undulations having a short cycle can be obtained.
It is a wave that is relatively easy to break, and has the effect of keeping the floating structure installed in the interior of the water calm by breaking the wave at the breakwater. In addition, long-period static vibrations, tsunamis, storm surges, tides, and the like are transmitted through the gaps in the embankment, and are gradually set in the water level over time, thereby being installed in the interior of the water body. This has the effect of holding the floating structure 2 calmly. Further, for swells, static vibrations, and tsunamis having a relatively short cycle (about 30 seconds to 30 minutes), the ratio (h / H) of the water depth h / offshore wave height H (h / H) at the front of the embankment to 2 or more. There is also an effect that the floating structure 2 installed in the interior of the water body is calmly held by reflecting waves when held deeply. ("Tsunami Protection System" Patent Publication No. 60-80611) [00019] Since the floating structure 2 installed in the interior of the water body is installed in the calming water area 3, the external force such as wave force is reduced, and the floating body is reduced. The stress applied to the mooring facility is small, which has the effect of reducing the size of the mooring facility and is economical. Since the floating structure 2 installed in the interior of the water body is installed in the calm water area 3, external force such as wave force is reduced, and it is possible to design the cross section of the stress member of the floating structure small. Made, great economic effect. As an enemy of the floating structure 2, there is a multi-gap in which contact or collision of a large drifting object such as a large ship with a broken stern line or a drifting ship whose main rudder cannot move during a typhoon is a major problem. By being surrounded by the breakwater 1, the large drifting material does not directly contact the floating structure 2, and the breakwater 1 having multiple voids plays a guard effect. [0002] Drift oil that has flowed out in large quantities in the event of a collision with a large tanker or the like poses a serious problem in terms of the function of the floating structure, as well as disaster prevention and the environment. Drifting oil exists in a liquid state, a state of floating as an oil ball, a state of floating in water, and a state of precipitation. Originally, as an oil property, it has a property of easily adhering to the surface of an object, and adheres to the surface of the embankment body by being surrounded by the wave breaking levee 1 having multiple voids. The breakwater 1 having multiple voids has a large surface area of the dam body, and this effect is large. Further, the oil ball is also protected by the filtering effect of the breakwater 1 having multiple voids. [00023] The safety of the floating structure 2 is also maintained by the breaking effect of the breakwater 1 having multiple voids even in the event of a fire caused by the collision or explosion of a large ship with the floating structure 2. There is a possibility that the floating structure 2 will sink due to torpedoes and submarine attacks. For this reason, it is possible to have a protective effect against direct attack from underwater by enclosing with the levee body structure of the breakwater 1 having multiple voids. In terms of safety and management of the floating structure 2, by surrounding the floating structure 2 with the breakwater 1 having multiple voids, the effect of directly protecting intruders such as sharks is great. For maintenance and maintenance of a floating structure, a calm water area surrounded by a breakwater having multiple voids is effective as an alternative space. In purifying the environment of the water around the floating structure 2, the natural purifying effect of water inside and outside the water area surrounded by a breakwater having multiple voids is great according to “Water Area Purification System” Patent Application No. 56-148107.
