Description

  The present invention is a tsunami countermeasure evacuation facility that is not an evacuation countermeasure that requires a huge amount of funding, such as moving up on a hill, as a countermeasure against a large tsunami. A facility that has the function of floating on the water of a tsunami. For example, if one is located within a walking distance of about 5 to 10 minutes, it will normally live on the current flat ground and a large tsunami will strike. In particular, the present invention relates to a tsunami countermeasure evacuation facility that allows an evacuated person to evacuate on foot and escape to the evacuation unit so as to respond to a tsunami in the vertical direction in the form of a floating ship and to avoid or reduce human life damage.

  In the Great East Japan Earthquake that occurred on March 11, 2011, many human lives were lost due to the great tsunami associated with the earthquake. This human life damage is mostly due to the tsunami that surpasses human knowledge, but it is thought that there are quite a lot of human disasters caused by flaws and deficiencies in tsunami countermeasures by politics and administration so far. By the way, conventional tsunami countermeasures are mainly tsunami blocking by embankments and revetments, and it is obvious that existing dykes and revetments will not be useful if a tsunami exceeding the assumed tsunami scale of embankments and revetments strikes. The damage caused by the great tsunami in the world was clearly shown to the public. After that, in the future large earthquakes such as the Tonankai earthquake, the possibility of the Great East Japan Earthquake or larger, and the accompanying tsunami will far exceed the tsunami associated with the Great East Japan Earthquake. It has been announced that it may be a tsunami. As a result of this influence, we have heard that future tsunami countermeasures will mainly be evacuated, and as an extreme countermeasure plan, there are plans for all residents to move up to high ground. However, it seems that no evacuation measures are being considered at this point in time, taking into account real life and economics.

  The areas affected by the tsunami are mostly near the coast, and it is considered that they are earning income from the industry related to the sea, etc. It is considered unrealistic to move to a high-altitude hill in order to deal with a tsunami that does not know when it will come or how big it will be.

  However, new measures against large tsunami are indispensable. For this reason, there is no need for enormous tsunami countermeasure funding, and there is no significant change in the current living infrastructure, while normally living in the same way as in the past. Proposals for measures that can be reduced are desired.

  By the way, Patent Document 1 and Patent Document 2 were detected as corresponding technical proposals as countermeasures for similar tsunami related to the title of the present invention. However, Patent Document 1 is accompanied by an evacuation tower having an evacuation section provided with an ascending / descending staircase for evacuation on the upper part of a fixed structure such as a police box, a fire station, a rescue station, and a nursing home. It is not a technically related prior document. Patent Document 2 is a structure composed of a multi-story floor having an evacuation floor surface at a position higher than the tsunami height where there is a possibility of invasion. Each floor is connected by a slope, and the refugee walks up using the slope. Thus, the evacuation facility can reach the evacuation floor, and is not applicable as the technically similar prior document of the present invention, as in the previous document.

  The problem to be solved by the present invention is that it is unrealistic to move all over the hills to counter tsunami that does not know when it will come and how big it will be. As a tsunami countermeasure at the place where the tsunami is supposed to hit, there is no need for huge tsunami countermeasure funds, and evacuates in the event of a large tsunami, usually living in the same way as before without greatly changing the current infrastructure It is to provide a tsunami countermeasure evacuation facility that can effectively prevent or reduce human life damage even if the person concerned evacuates on foot.

  In order to solve the above-mentioned problem, the tsunami countermeasure evacuation facility of the present invention is an evacuation facility that is assumed to be disposed at about one place within a range of about 5 to 10 minutes on foot, and is not destroyed by a large tsunami. It has a flat foundation, and at the top of the flat foundation, there are four pillars with a height higher than the assumed upright tsunami height in the shape of a cylinder or a square tube, and is surrounded by the pillars at the four corners. On the inner side, there is a floating bottom that can prevent water intrusion, a wall with a door, and a waterproof function space surrounded by a ceiling, and an evacuation space for people with an evacuation floor. In contrast, it has a floating part that has a function of floating like a ship, and a scaffold and a staircase or ladder for evacuation to the floating part are provided in the vicinity of the outer periphery of the floating part, corresponding to the water of the tsunami , So that the floating body can slide up and down with the pillars at the four corners as guides The most important feature that has a sliding mechanism that.

  In addition, a handrail is arranged on the outer peripheral part of the roof top of the floating body part so that the roof can be evacuated, and the roof part is provided with hatches that can enter and exit the roof. And

  In addition, the present invention is characterized in that a space for storing disaster countermeasure stockpile is provided under the floor of the evacuation space.

  In addition, a support member for allowing tsunami water to pass under the floating body portion and effectively floating the floating body portion is provided.

  In addition, an evacuation scaffolding portion is attached using the reinforcing member of the pillar portion, and a ladder for reaching the evacuation scaffolding portion is attached.

According to the tsunami countermeasure evacuation facility of the present invention, as a tsunami countermeasure in a place where a large tsunami is supposed to come, without changing the current living infrastructure, usually living in accordance with the conventional tsunami countermeasures It is possible to avoid or reduce human lives effectively in the event of a major tsunami attack without the need for funds.
Moreover, it can be used not only as a countermeasure against tsunami but also as an evacuation facility against heavy rain and flood damage in areas where there is a possibility of flood damage due to abnormal water increase during heavy rain, such as a ground zone with a low river basin.

  And the supporting member 5 for ensuring space is arrange | positioned so that the water of a tsunami may be passed through the lower part of the floating body part 3, and the floating body part 3 can be lifted effectively.

An evacuation scaffold portion 7 is attached using the reinforcing member 6 of the pillar portion 2, and a ladder 8 for reaching the evacuation scaffold portion 7 is attached. Further, in order to maintain safety during movement / standby in the evacuation scaffolding portion 7, a lifeline hanger bar 9 is attached to the lower part of the reinforcing member 6, and the lifeline is hung on this. Evacuees maintain their safety by using their lifeline.
Then, when evacuating from the outside to the evacuation space 32, the stairs 41 for evacuation to the floating body 3 is basically run up from the scaffolding 4 to the evacuation space 32 from the door 31 e of the wall. Further, when the evacuation from the door 31e to the evacuation space 32 is not in time, the ladder 31j for evacuating from the outside to the rooftop is used, or the ladder 8 for arriving at the evacuation scaffolding 7 attached to the pillar 2 Is used to evacuate from the refuge scaffolding section 7 to the roof of the floating body section 3.
Hereinafter, what should be specially described for the main parts and members of the device of the present invention will be described.

  The flat foundation 1 is preferably reinforced concrete. The size of one side, the thickness dimension, and the like are appropriately set based on the estimated tsunami height and the desired scale of the floating body 3. Moreover, it is preferable that the foundation pile 101 is arrange | positioned suitably.

  Basically, the column part 2 is preferably a cylindrical or rectangular steel pipe, but is not limited thereto. Specifications such as dimensions and column spacing are appropriately set in relation to the estimated tsunami conditions and the desired size / conditions of the floating body 3. Further, the reinforcing member 6 is preferably angle steel or groove steel, but is not limited thereto. And the joining of the column part 2 and the reinforcement member 6 is joined via a joining member.

The size and specifications of the floating body 3 may be appropriately set according to desired conditions and the like, and are not limited as long as the object of the present invention can be achieved, but the size of one side is, for example, about 3 to 5 m. It is preferably set within a range of dimensions. The material is not limited as long as it can achieve the object of the present invention. For example, iron, stainless steel, aluminum or an alloy thereof, fiber-reinforced reinforced plastic, and the like are preferable, and the specific gravity is as light as possible. The material is preferred.
In particular, the floating body bottom 31a also takes into account the collision of drifting objects. For example, it is possible to consider the surroundings in a form that is less likely to be deformed or damaged, such as a slope form or a ship bottom form, and the material used. preferable.
The door 31e of the wall preferably has at least a transparent part that allows visual confirmation of the external situation, and is a mechanism having a waterproof function. The opening / closing method may be a hinged door type or a sliding door type, and may be determined as appropriate.
The evacuation space 32 is preferably provided with a gripping bar and the like, and a soft member is attached to the inside of the floor, wall, and ceiling to take measures to avoid injury such as bruise.
The slide mechanism portion 35 that can be slid by fitting with the column portion 2 has a mechanism / form so that the floating body portion 3 does not protrude from the inside of the column portion 2 at the four corners. For example, the roller mechanism and the frictional resistance are small. Although the thing of the mechanism incorporating a sliding member is considered, if it has a slide mechanism which can achieve the object of the present invention, it will not be limited. And since the fluctuation | variation permissible space | interval between the structure parts with respect to the influence of a tsunami is needed, it is preferable to incorporate an elastic member or a spring material etc. as the countermeasure.

  The scaffold 4 and the staircase 41 may be appropriately disposed depending on the conditions of the installation location of the evacuation equipment, but it is preferable that the scaffold 4 and the stairs 41 be evacuated to the floating body portion 3 from four directions as much as possible. The width of the scaffold 4 is not limited, but is preferably at least about 50 cm to 1 m. Moreover, it is preferable that the staircase 41 has a form that allows tsunami water to easily pass between the treads.

  The support member 5 for securing a space below the floating body portion 3 circulates tsunami running water below the floating body portion 3 to effectively lift the floating body portion 3. Arrange appropriately. Moreover, it is preferable to attach an elastic member such as a rubber material at a contact portion between the floating body portion 3 and the support member 5. And although the height of the supporting member 5 is not limited, about 30-50 cm is suitable.

  The refuge scaffolding part 7 using the reinforcing member of the column part is installed using the reinforcing member 6. And although the width | variety of the refuge scaffold part 7 is not limited, It is preferable that it is about 50 cm-about 1 m. And it is preferable to attach a minimum handrail-like member.

  The ladder 8 for arriving at the evacuation scaffold part 7 is preferably in a form that can be lifted by human power, arranged on the side part of the evacuation scaffold part 7, and in a form that can be directly reached to the top.

  The lifeline hanger bar 9 is configured such that the lifeline can be always suspended in one corner, and the escape scaffold 7 can be moved using the lifeline.

By the way, since there are many cases where drifting objects accompany large tsunamis, when installing the tsunami countermeasure equipment, the wall surface of the floating body 3 is directly opposed to the direction in which the large tsunami is likely to strike. Instead, it seems that it is effective in terms of countermeasures for drifting objects to be arranged so that one column part 2 is inclined as a tip part. In addition, since it is not known when the big tsunami will come, a solar power generation facility will be attached to the roof of the floating part 3, the refuge scaffolding part 7, etc., a disaster prevention broadcast speaker will be attached to the pillar part 2, etc. The space 33 that can store the stockpile for countermeasures may be effectively used as a storage place for normal equipment for disaster prevention training, public backup materials for disaster response, and the like. And the floating part 3 may be effectively utilized as a disaster response educational facility.
