Description

The present invention relates to a tsunami evacuation facility comprising an evacuation boat that accommodates evacuees in the event of a disaster such as a tsunami, its installation base, and a wave removal block that protects the evacuation boat from debris caused by the tsunami.

There is a safeguard tower (evacuation tower) as an evacuation facility against tsunami. The safeguard tower is known as a public evacuation facility because it is a steel structure and is less damaged by waves. In addition, capsule-type evacuation shelters have been devised for small-scale evacuation structures.

In the Great East Japan Earthquake, there were many residents who were unable to escape to the evacuation site corresponding to the tsunami and were sacrificed. There are also many people who stayed in the alert area under imminent circumstances and suffered during public affairs such as evacuation guidance for residents and operation of breakwaters. In the future, there are few effective evacuation facilities and evacuation sites that can evacuate quickly as large-scale earthquake disasters are expected. There are also many areas where large-scale facilities cannot be built.

While safeguard towers (evacuation towers) are easy to construct and are considered effective against tsunamis, the Great East Japan Earthquake caused a tsunami that was much higher than expected. There are some difficult to set scales. Considering the fact that not only real estate, but also telephone poles and railway lines and other unpredictable items and facilities were damaged, there are some things that are difficult to install in areas where liquefaction is likely or where the ground is poor.

Since the prior art evacuation shelter is a mooring type facility, it is thought that the impact vibration impact on the internal refugee is large due to the collision of obstacles and rubble around the facility. In addition, its capacity for accommodating people is low, making it unsuitable for public evacuation facilities.

The Great East Japan Earthquake caused tremendous damage in the Tohoku region due to the earthquake and tsunami. In particular, there were many sacrifices in the areas affected by the tsunami. Buildings and other real estate are also devastating. Under such circumstances, it is possible to confirm many things that are not seriously damaged, such as ships and cars, that float on the water and do not oppose the energy of the tsunami. Therefore, as a measure to protect the lives of evacuees against unforeseen tsunamis, it is effective to make the evacuation facility a structure that floats on water like a ship and drift without countering the energy of the tsunami.

The present invention is a tsunami evacuation facility composed of an evacuation boat 2, a wave removal block 3 and an installation stand 4 characterized by a pan-bottom circular ship, and is used as an evacuation facility in response to an emergency. When a tsunami occurs, as a facility that protects evacuees from rushing waves and debris, when a tsunami that exceeds the amount of water discharged from the evacuation boat 2 occurs, the evacuation boat 2 drifts against the tsunami energy Become a ship and protect the lives of evacuees.

By making the hull 5 of the evacuation boat 2 into a pan-bottom type circular ship, the resistance to running water can be lowered, and at the same time, it is possible to achieve the ability to accommodate personnel, stability during installation, and stability during drifting. In addition, a bumper 6 made of a composite agent such as a steel pipe or a synthetic resin material is provided around the evacuation boat 2 to give the evacuation boat 2 the strength, while colliding with an obstacle at the time of drifting, pushing rubble, etc. To prevent the evacuation boat 2 from being damaged and to make the refugees safe.

The wave removal block 3 is a structure installed in an expected direction in which a tsunami comes to the evacuation boat 2, and prevents the evacuation boat 2 from being damaged or overturned by waves or rubble. Inside, a mooring release impact mitigation device 16 is installed, and the evacuation boat 2 is kept moored until reaching a dangerous water level that exceeds the drainage amount of the evacuation boat 2, and when the dangerous water level is reached, the mooring state is released. At that time, in order to prevent an impact caused by a sudden flow, the mooring is gradually lifted to ensure the safety of evacuees.

The installation table 4 is a structure that holds the evacuation boat 2 in a stable state, and is made of a metal material, a concrete material, sand, gravel, or the like according to the installation location or installation environment.

The present invention is a land-based tsunami evacuation facility that can be installed if the evacuation boat 2 and the wave removal block 3 are wide, so that there are no effective evacuation facilities, infant facilities that require time for evacuation, and unhealthy people Many people's lives can be protected by installing them on the site, rooftop, park, open space, etc. Since large-scale ground construction is not required, it can be installed in areas where liquefaction is likely to occur due to earthquakes.

The present invention is a tsunami evacuation facility composed of an evacuation boat 2 characterized by a pan-bottom circular ship, a wave removal block 3 that protects the evacuation boat 2 from rubble that is pushed by the tsunami, and an installation table 4 on which the evacuation boat 2 is installed. In the event of a tsunami, as a facility that protects evacuees from rushing waves and debris, when a tsunami exceeding the drainage volume of evacuation boat 2 occurs, evacuation boat 2 drifts against the tsunami energy. It is a ship that protects the lives and safety of evacuees.

By making the hull 5 of the evacuation boat 2 into a pan-bottom type circular ship, it is possible to reduce the resistance to running water and to improve the capacity for accommodating personnel and the stability during installation and drifting. Around the evacuation boat, a bumper 6 made of a composite agent such as a steel pipe or synthetic resin material is provided to give the evacuation boat 2 strength, and evacuate from a collision with an obstacle during drifting, rubble that pushes in, etc. Prevent damage to the boat 2 and ensure the safety of evacuees in the evacuated boat.

It can be installed in various places, and it can be installed on the premises of buildings, rooftops of buildings, parks and open spaces, such as bay areas where there are no evacuation areas, infant facilities that require time for evacuation, and facilities where non-healthy people are located. You can protect many lives. Since large-scale ground construction is not required, it is also effective in areas where liquefaction is likely to occur due to earthquakes, and construction sites that require temporary evacuation facilities.

It is a perspective sectional view showing one example of a shape of a wave removal block. It is a perspective view of an example of the shape of the installation table.

The present invention includes an evacuation boat 2 that accommodates refugees, a wave removal block 3 that protects the evacuation boat 2 from a tsunami with rubble, and an installation table 4 on which the evacuation boat 2 is installed.

By reducing the hull 5 of the evacuation boat 2 to a pan bottom circular ship, the resistance to running water is reduced, and the capacity for accommodating personnel and the stability during installation and drifting are improved. A bumper 6 made of a composite agent such as a steel pipe or a synthetic resin material is provided around the evacuation boat so that the strength of the evacuation boat 2 is increased, and the evacuation boat 2 is struck by a collision with an obstacle at the time of drifting or a debris that approaches the evacuation boat 2. Prevent damage. In addition, a roof 8 is provided to prevent the intrusion of water such as waves into the evacuation boat, thereby ensuring the safety of refugees in the evacuation boat.

The refuge boat 2 is provided with an indicator lamp 13 and a sign indicating drifting, and equipped with a kite, a mooring rope, an escape shooter or ladder, and lifesaving equipment used at the final drifting point.

The wave removal block 3 is installed in an expected direction in which a tsunami comes to the evacuation boat 2, and prevents the evacuation boat 2 from being damaged or overturned by waves and rubble. Further, the wave removal block 3 is provided with stairs, ladders or slopes to facilitate evacuation into the escape boat.

The wave removal block 3 is provided with a mooring release impact mitigation device 16, which keeps the moored state so that the evacuated boat will not be washed away at a water level below the evacuated boat's drainage amount or a water level set in consideration of safety. If the water level exceeds the critical water level or exceeds the set water level, the mooring of the ascending evacuation boat is lifted. At that time, the mooring rope 12 is gradually unwound so as not to be swept away suddenly, thereby ensuring the safety of the refugees in the escape boat.

The installation table 4 holds the evacuation boat 2 with a concrete structure, a structure configured in a tower shape with steel pipes, sand, gravel, or the like in consideration of the installation location, environment, and situation.
