Since the air tightness of the evacuation room 3 does not depend on the opening/closing of an entrance door 8, there is no need for closing the door 8 during evacuation and no fear that the entrance 2 is blocked during escape. The inclination of the outer wall, the sufficient dead weight of the tsunami shelter 1 itself, and fixture 5 to a ground function to resist the pressure of tsunami waves and collision 18 with rubbles swept away by the tsunami waves.

Description

本発明は津波から人命を守る避難施設に関するものである。  The present invention relates to an evacuation facility for protecting human lives from a tsunami.
東日本大震災において津波の高さは場所によっては20メートルを越し、地震とそれに続く津波により木造、鉄骨造や鉄筋コンクリート造の建物の多くが倒壊し、残った建物の屋上に避難した多数の方々も屋上を遙かに超える津波に流された。確実に逃げるためには津波の到達地点より高い場所への避難が必要であるが、周りに高台がない場所や、子供、お年寄り、障害者の単独での避難は困難である。この為、確実に人命を保護できる施設が身近に必要である。従来のシェルターは地下室式のものと、地上に設けられ避難室が浮上式の物(特許文献1及び2参照)がある。
特開3541197号 特開2006−226099号
In the Great East Japan Earthquake, the height of the tsunami exceeded 20 meters depending on the location, and many wooden, steel and reinforced concrete buildings collapsed due to the earthquake and subsequent tsunami, and many people who were evacuated to the rooftop of the remaining buildings were also on the rooftop It was swept away by a tsunami that far exceeded. To evacuate reliably, it is necessary to evacuate to a place higher than the tsunami arrival point, but it is difficult to evacuate places where there are no hills, children, the elderly, and the disabled alone. For this reason, facilities that can protect human lives are necessary. Conventional shelters include those in the basement type and those in which the evacuation room is levitated (see Patent Documents 1 and 2).
Japanese Patent No. 3541197 JP 2006-226099 A
地下室にシェルターにおいては、入り口の扉を閉め水の侵入を防ぐ事になるが、逃げ遅れた人の避難を考えると閉めるタイミングが難しく、閉め遅れたり隙間があると浸水してしまい、また、入り口が水や瓦礫や土砂に塞がれると脱出も困難になる。上記特許文献1及び2では浮遊式の避難室にて津波を避ける構造であるが、この構造では津波に流された家や船舶や無数の瓦礫の衝突が予想される。更に引き波にもさらされる為、この場合浮遊式ではシェルター自体の破損は避けられず、運良く衝突が避けられた場合しか生き残れない。本発明の津波シェルターは、上記問題点を解消する為に、津波の下で水が引くまでの安全を確保し、津波の潮位や威力に関係なく効果的な避難施設を目的とする。  In the shelter in the basement, the entrance door is closed to prevent water from entering, but considering the evacuation of people who are late to escape, the timing to close is difficult, and if there is a delay or there is a gap, it will be flooded, and the entrance If it is blocked by water, rubble or earth and sand, it will be difficult to escape. In the above Patent Documents 1 and 2, the structure is a structure that avoids a tsunami in a floating evacuation room, but in this structure, a house, ship, and countless rubble that are swept away by the tsunami are expected. Furthermore, since it is also exposed to a pulling wave, in this case, damage to the shelter itself cannot be avoided in the floating type, and it can survive only when the collision is fortunately avoided. In order to solve the above problems, the tsunami shelter according to the present invention secures safety until water is drawn under the tsunami, and aims at an effective evacuation facility regardless of the tide level and power of the tsunami.
津波シェルターの入り口からの連通路天井部の最下部よりも避難室の最低部位を高くし、開口部を入り口のみとすることにより空気を閉じ込め水の侵入を防ぎ、被災時には酸素ボンベ又はエアーボンベにより内部に酸素を供給し、内部の空気の量を必要に応じて増加させることで避難者の生命を保護する。  The lowest part of the evacuation room is made higher than the lowest part of the ceiling of the communication passage from the entrance of the tsunami shelter and the opening is used only as an entrance to prevent air from entering, and in the event of a disaster, use an oxygen cylinder or air cylinder. Protect the lives of evacuees by supplying oxygen inside and increasing the amount of air inside as needed.
津波シェルター本体の外壁に傾斜を付けることと、津波シェルター自体の十分な自重と地盤への固定により被災時の津波の圧力や津波に押し流された瓦礫、建築物、船舶の衝突に耐える。  The outer wall of the tsunami shelter body is inclined, and the tsunami shelter itself is fully weighted and fixed to the ground to withstand tsunami pressure and rubble, buildings, and boats swept away by the tsunami.
津波シェルター本体を地上に設け、入り口を開放状態にすることで、瓦礫が入り口の扉を塞ぎ水が引いた後の脱出の妨げになることを防ぐ。  By installing the tsunami shelter body on the ground and opening the entrance, it prevents the debris from blocking the entrance door and preventing escape after water is drawn.
津波シェルター内部に空気を閉じ込め、被災時に中に逃げこむだけの構造なので、体力の無い高齢者や子供でも簡単に活用でき、内部の酸素ボンベ又はエアーボンベと非常食により長期間の避難に活用できる。  Because it is a structure that only traps air inside the tsunami shelter and escapes in the event of a disaster, it can be easily used by elderly people and children without physical strength, and can be used for long-term evacuation by internal oxygen cylinder or air cylinder and emergency food .
津波シェルター本体を浸水時の浮力より重くし、強固に地盤へ固定し、外壁に傾斜を設けることで津波シェルター本体が津波の圧力により流されるのを防ぎ、瓦礫や船舶の衝突で津波シェルターが破損されることに耐えることが出来る。  The tsunami shelter body is heavier than the buoyancy at the time of flooding, firmly fixed to the ground, and the outer wall is inclined to prevent the tsunami shelter body from being washed away by tsunami pressure, and the tsunami shelter is damaged by debris and ship collision Can withstand being done.
津波シェルターを地上に設けることと入り口を開放しておくことで、被災後瓦礫や水などが入り口を塞ぎ脱出を妨げることを防ぐ。  By installing a tsunami shelter on the ground and opening the entrance, we will prevent rubble and water from blocking the entrance and preventing escape after the disaster.

本シェルターの本体1は、人命を保護する避難室3を強固な外壁17で覆い、入り口2の連通路天井最下部15より避難室3の内部の床12を高くすることで避難室3をエアーポケットとする構造であり、避難時に酸素ボンベ又はエアーボンベ10により内部の空気量を増加させ人命を保護する。また、シェルター本体1は基礎杭5により強固に地面に固定される。入り口2に続く連通路には扉6又はシャッターが取り付けられ、内側に開く7ことにより、避難者16が素早く内部に入れ、内側に開放状態8にすることで脱出を妨げない効果がある。また、入り口及び連通路2にはスロープ4が設けられ、お年寄りや車椅子、ベビーカーでの迅速な避難を可能にする効果がある。設置場所を地図に記載し内部に発信機9を設置することにより、被災後の人命を容易に救助出来る効果がある。  The main body 1 of this shelter covers the evacuation chamber 3 that protects human lives with a strong outer wall 17, and raises the floor 12 inside the evacuation chamber 3 from the bottom of the communication path ceiling 15 at the entrance 2, thereby allowing the evacuation chamber 3 to air. It has a pocket structure, and protects human life by increasing the amount of air inside by an oxygen cylinder or air cylinder 10 during evacuation. The shelter body 1 is firmly fixed to the ground by the foundation pile 5. A door 6 or a shutter is attached to the communication path following the entrance 2, and the opening 7 opens inward, so that the refugee 16 can quickly enter the inside and open the inside 8 to prevent the escape. In addition, a slope 4 is provided at the entrance and the communication path 2, which has the effect of enabling quick evacuation by the elderly, wheelchairs, and strollers. By describing the installation location on the map and installing the transmitter 9 inside, there is an effect that the life after the disaster can be easily rescued.
被災時には津波シェルター本体1が津波の水面11より下に水没する形になるが、内部に侵入した海水面13が入り口連通路2の天井最下部15までの高さとなり、避難室3の床面12より常に下に位置する。そして、内部の空気を逃がさない気密性の構造と酸素ボンベ又はエアーボンベによる空気の放出14で避難室3の避難者16を保護する。津波により流れて衝突する瓦礫18などは強固な外壁17に傾斜を付けることで耐えることが出来る。  In the event of a disaster, the tsunami shelter body 1 is submerged below the water surface 11 of the tsunami, but the sea level 13 that has entered the interior reaches the bottom of the ceiling 15 of the entrance passage 2 and the floor of the evacuation chamber 3 Always below 12. And the refugee 16 of the evacuation chamber 3 is protected by the airtight structure which does not let internal air escape, and the discharge | release 14 of the air by an oxygen cylinder or an air cylinder. The debris 18 that flows and collides with the tsunami can be resisted by inclining the strong outer wall 17.
本シェルターの本体1は、設置する土地の利用形態によってシェルター底面及び避難室の形を四角形や多角形、円、楕円に変えることができる。シェルター本体1は内部に収容する予定の人数に応じて大きさを変えるが、常に避難室の浮力よりもシェルターの自重が大きくなるようにする。入り口2の高さを低くすることによりシェルター本体1を小型化することが出来る。多人数を収容する大型の場合は内部に天井を支える支柱を有する。  The main body 1 of the present shelter can change the shape of the bottom surface of the shelter and the evacuation room into a square, a polygon, a circle, or an ellipse according to the use form of the land to be installed. The shelter body 1 varies in size according to the number of people scheduled to be accommodated therein, but the weight of the shelter is always greater than the buoyancy of the evacuation room. The shelter body 1 can be downsized by reducing the height of the entrance 2. In the case of a large size that accommodates a large number of people, it has a support column that supports the ceiling inside.
海に面し避難できる高台が近くにない場所や海岸線付近の家屋、港湾施設に隣接して設置し付近に明示する。建築物自体にシェルター本体1を組み込み、シェルター本体1の上部に住居部分を建てることが可能である。  It should be installed next to places near the sea where there are no hills that can be evacuated, houses near the coastline, and port facilities.
