Fishing port coexisting with tsunami

Abstract

To provide a fishing port that coexists with tsunami, where people can live by the sea, watching the sea, even if a large tsunami comes.SOLUTION: A fishing port that coexists with tsunami is built on a platform supported by large RC pillars, similar to those supporting a highway, such that tsunami can "come and go" beneath the platform. It is proposed to construct such fishing ports in various locations.SELECTED DRAWING: Figure 1

[0002] During the Great East Japan Tsunami, wooden houses were washed away by the tsunami, but the frames of reinforced concrete and steel-framed buildings were not washed away. The piers of bridges over rivers are always standing in the flow of water. If we erect several thick pillars like those that support highways, elliptical like boats, parallel to the flow of water, and allow the tsunami to go back and forth between the pillars, I think we can create buildings that can accept the tsunami without resisting it. Challenges During the Great East Japan Tsunami, I learned from the news that fishermen on the beach said they did not want to move to higher ground, but wanted to always be near the sea and look at it. I think there may be a way to accept the tsunami without resisting it as a tsunami countermeasure. Solutions to the problem Build two or more thick pillars like those that support highways, elliptical like boats, parallel to the flow of water. 1. Beams are placed on top of pillars, and then a slab is placed on top of that, like a highway, and this becomes the platform: floor. 2. The first floor will be on top of this RC floor, and a seafood processing factory will be built first. 3. Wooden houses for the fishermen will be built on top of the seafood processing plant. 4.Wooden houses will be two or three stories high, as necessary. 5. If necessary, it would be possible to make the first floor out of reinforced concrete and then place a wooden third floor on top to make a four-story building. 6. Buildings like this part of the highway are built on the seashore at right angles to the tsunami, making it easier for the tsunami to "come and go" between the boat-shaped pillars. 7. All the houses are built facing the sea, so the fishermen can see the sea every day. 8. The height of the platform on the pillars needs to be estimated based on the height of a large tsunami that occurs once every 800 years. If it is 30m above sea level, the tsunami will "run back" below it. 9. A large lift is needed to transport supplies to a fishery processing factory located 30 meters above sea level. The large lift and the emergency stairs are located in the center of a thick oval pillar. 10. Entrances to large lifts and evacuation stairs will be equipped with doors that can be closed electrically or manually in the event of a tsunami to prevent water from entering. 11. Wide roads are required in front of and behind the fish processing plant to allow transport vehicles to pass through. 12. Seafood from the ocean and seafood processed in factories could be transported by conveyer belts, but a tsunami would wash this away. 13. Tsunamis come and go around this fishing port, so houses cannot be built there. Depending on how often the tsunamis come, the land will either be used for farming or left as green space. [Brief description of the drawings]

[0003] [Figure 1]A-1 Floor Plan 1 / 500 Basement: Tsunami-resistant pillars - Thick pillars like those supporting a highway, oval shaped like a ship, parallel to the current, will be built in two or more pieces. - A building like part of this highway will be built on the seashore at a right angle to the tsunami, making it easier for the tsunami to "return" between the ship-shaped pillars. - Elevators will be installed inside the pillars to allow the transport of people and goods. 1st floor: Seafood processing plant - Beams will be placed from pillar to pillar on top of the pillars, and a slab will be placed on top of that, like a highway, and this will be the platform: floor. - The first floor will be on top of this RC floor, and the seafood processing plant will be built first. - Wide roads will be built in front and behind the seafood processing plant so that transport vehicles can pass back and forth. - The height of the platform on top of the pillars will need to be estimated based on the height of a large tsunami that occurs once every 800 years. If it is 30 meters above sea level, it will be 30 meters above sea level, and the tsunami will "run back" underneath it. - A large lift is needed to transport supplies to the fishery processing plant, which is just over 30 meters above sea level. The large lift and the evacuation stairs will use the center of the thick oval pillar. 2nd floor: Housing for fishermen - Wooden houses for the fishermen will be built on top of the fishery processing plant. - The wooden houses will be 2 or 3 stories high, depending on the need. - If necessary, the first floor will be made of reinforced concrete, and a wooden third floor will be placed on top of that, making it a 4-story building. - All the houses are built facing the sea, so the fishermen can see the sea every day. [Diagram 2]A-2 Elevation 1 / 500 Front elevation - Tsunamis will "ebb and flow" between the large pillars that support the three expressways. - The height of the slab on top of the pillars will be estimated based on past performance. - Above the slab is the fishery processing plant, and above that are the homes of the fishermen. - Depending on the need, they will be two, three, or four stories tall. - Each building will have four residences, with some space between the buildings to harmonize with nature, for a total of about five buildings. - The height will not be uniform, but will be different to harmonize with the surrounding nature. Side elevation - The first floor entrance to the large lift and evacuation stairs will have a door that can be closed electrically or manually in the event of a tsunami to prevent water from entering. - The front and rear of the fishery processing plant will be roads that allow transport vehicles to pass by. - The central transition in the roof of a wooden house allows natural light to enter the center of the house. [Diagram 3] A-3 Bird's-eye view 1 / 1000 - This is an overall view of the fishing port with the tsunami, seen from a high place as if it were a bird's-eye view. - The tsunami "flows in and out" between three large pillars. - The platform on which the fishery processing factory is located is above the expected tsunami. - There are roads in front and behind the fishery processing factory that cars can use. - There are general roads around the fishing port. - The general roads also surround cultivated land. - The fishing port is near the sea, and is built facing the sea. - The fishing port buildings, parking lot, work area, and sea are lined up in that order. [Figure 4] A-4 Perth - The flat parts of the alluvial fan are suitable for farming. This will be left as farmland, green space, and wetlands. - Housing will be built on the surrounding high ground to avoid tsunamis. - The fishing port is on flat land by the sea, on an alluvial fan where a river flows into the sea, so fishermen can see the ocean every day.

Claims

[Claim 1] This is a way to prevent seafood processing factories and fishermen's homes from being swallowed up by a tsunami.
