Description

本発明は、津波からの避難装置に関する。 The present invention relates to an evacuation device from a tsunami.

古来から巨大地震が発生すると当然のように津波（非常事態の１つ）が発生し、この津波は海岸線から押し寄せて大勢の人や民家などを呑み込み甚大なる被害を与えてきたことはよく知られている。 It is well known that a huge earthquake has occurred since ancient times, and a tsunami (an emergency situation) occurred as a matter of course, and this tsunami swept from the coastline and swallowed many people and private houses. ing.

しかし、これまでは、大規模な堤防や水門を造って津波に対処するだけで、安価で有効な津波対策は講じられていなかったのが実状である。 However, until now, it was the case that only a large dyke or sluice was built to deal with the tsunami, and no cheap and effective tsunami countermeasures were taken.

上記課題を解決するため、請求項１記載の発明は、地盤に埋設されたコンクリート基礎を介して立ち上がるようにして立設される支柱と、津波発生時の想定水位を超えるべく支柱の高い位置に設けられた高所避難場所と、地上からの避難者を高所避難場所に導くことのできる昇降手段と、支柱防護手段とを備え、前記支柱防護手段は、前記支柱の基部まわりにおいて上面が球面の一部の形状をして地盤上に盛り上がり下部が地盤内に埋設固着された状態のカバーリング基礎として構成されていることを特徴とする。
請求項２記載の発明は、請求項１記載のものにおいて、カバーリング基礎内には、支柱側から延びた骨材が埋設されている。
請求項３記載の発明は、地盤に埋設されたコンクリート基礎を介して立ち上がるようにして立設される支柱と、津波発生時の想定水位を超えるべく支柱の高い位置に設けられた高所避難場所と、地上からの避難者を高所避難場所に導くことのできる昇降手段と、支柱防護手段とを備え、前記支柱防護手段は、コンクリート基礎側から支柱の基部まわりを取り囲むように立ち上がる複数本のアンカーと、これらのアンカーを互いに結合する連結材とでなることを特徴とする。In order to solve the above-mentioned problems, the invention according to claim 1 is a structure in which a support column is installed so as to stand up through a concrete foundation embedded in the ground, and the support column is positioned higher than the assumed water level when a tsunami occurs. Provided with a high place evacuation place provided, elevating means capable of guiding refugees from the ground to the high place evacuation place, and a pillar protection means, and the pillar protection means has a spherical upper surface around the base of the pillar. It is characterized in that it is configured as a covering base in a state where a part of the shape is raised and the raised bottom is buried and fixed in the ground.
According to a second aspect of the present invention, in the first aspect of the present invention, an aggregate extending from the support column side is embedded in the covering base.
The invention according to claim 3 is a post disposed to stand up through a concrete foundation buried in the ground, and a high place evacuation site provided at a high position of the post so as to exceed an assumed water level at the time of tsunami occurrence And elevating means capable of guiding evacuees from the ground to a high-level evacuation site, and supporting means for supporting pillars, wherein the supporting means for supporting pillars stand up to surround the base of the supporting pillar from the concrete foundation side. It is characterized by comprising an anchor and a connecting material for connecting these anchors to each other.

本発明によれば、比較的安価に済み有効な避難場所として機能を発揮できる津波からの避難装置を提供することができる。 According to the present invention, it is possible to provide a tsunami evacuation device that can function as an effective evacuation place that is relatively inexpensive.

BEST MODE FOR CARRYING OUT THE INVENTION

図１から図３は、本発明に係る津波からの避難装置の一実施形態を示す。以下、こうした他の実施形態でも同様に適用できることを意味する表示として、適用される文の段落後に上記のような…Ａを付すものとする。
図１から図３の実施形態は、支柱４６を連結梁４７で連結したタワー構造物に作用する津波Ｘの掬いおよび浮揚力に対するものである。図２および図３がその具体例で、支柱４６は、地盤４８内に埋め込まれたコンクリート基礎４９上にフランジ５０を介してアンカー５１で連結固定されているが、支柱４６の基部に、先端が下向きに湾曲するアングル材などによる骨材５２を放射状に伸びた形で固定し、これら骨材５２を埋め込むようにモルタルやコンクリート、アスファルトなどによりカバーリング基礎５３を付設したものである。この場合、同基礎５３の上面は球面の一部で形成されるとともに下部が地盤４８内に埋設された状態にして、津波Ｘの流れがその上を通過しタワー基部を掬い上げないようにしてある。また、同基礎５３の付加により前支柱４６の浮揚が阻止される。アンカー５１と骨材５２とはアンカー５１を長くすることで互いに連結することができる…Ａ。1 to 3 show an embodiment of an evacuation device from a tsunami according to the present invention. In the following, as a display meaning that the present invention can be similarly applied to such other embodiments, the above-described...
The embodiment of FIGS. 1 to 3 is for the tsunami X creeping and levitation force acting on the tower structure in which the columns 46 are connected by the connecting beams 47. 2 and 3 are specific examples, and the column 46 is connected and fixed to the concrete foundation 49 embedded in the ground 48 by an anchor 51 via a flange 50. The tip of the column 46 is at the base of the column 46. An aggregate 52 such as an angle material that curves downward is fixed in a radially extending form, and a covering base 53 is attached by mortar, concrete, asphalt or the like so as to embed these aggregates 52. In this case, the upper surface of the foundation 53 is formed as a part of a spherical surface and the lower part is embedded in the ground 48 so that the flow of the tsunami X does not pass over the tower base. is there. In addition, the addition of the foundation 53 prevents the front column 46 from floating. The anchor 51 and the aggregate 52 can be connected to each other by making the anchor 51 longer ... A.

図４の実施形態は、骨材５２を水平にしたもので、フランジ（孔付きでもよい）にしてもよい。 In the embodiment of FIG. 4, the aggregate 52 is horizontal and may be a flange (may be provided with a hole).

図５の実施形態は、線条材５６によりタワー構築体を引張支持する方式のものにおいて、同線条材５６が津波Ｘなどの流れで掬い上げられずしかも切断されないように防護をする施工方法およびその構造に関する。すなわち、５７は地盤で、同地盤５７に穴５８を掘り下げ、その底を介して補助杭５９付きで本杭６０を打ち込み、この本杭６０に線条材５６の端部を連結したあと、コンクリート（あるいはモルタルやアスファルト、岩石など）６１を埋設固着する。その前に線条材５６の地表面を境にする高さ位置に孔付き球体６２を備え付けておき、コンクリート６１と同時に下部を埋設するようにする。球体６２は、コンクリートや、ゴム、樹脂などでなり、上下に（あるいは周方向）に分割形で合体する方式のものでもよい。その上に更に球体６２を付加してもよい。また、線条材５６まわりにはゴムや樹脂チューブなどの防護材６３を被せてより完全な防護をしてもよい…Ａ。 The embodiment of FIG. 5 is a method of protecting the tower structure so that it is not scooped up by a flow of tsunami X or the like and is not cut in a system in which the tower structure is pulled and supported by the wire material 56. And its structure. That is, 57 is a ground, a hole 58 is dug into the ground 57, a main pile 60 is driven through the bottom with an auxiliary pile 59, and the end of the wire 56 is connected to the main pile 60. 61 (or mortar, asphalt, rock, etc.) is buried and fixed. Before that, a holed sphere 62 is provided at a height position bordering on the ground surface of the wire material 56, and the lower part is buried simultaneously with the concrete 61. The spherical body 62 is made of concrete, rubber, resin, or the like, and may be of a type that is united in a vertically divided manner (or circumferential direction). Further, a sphere 62 may be added thereon. Further, a protective material 63 such as rubber or a resin tube may be put around the wire material 56 to provide a more complete protection.

尚、線条材５６を地盤に直接打ち込んだ杭により連結固定する場合には、その周りにモルタル等を流し固めて球面状あるいは円錐状に防護することができる…Ａ。 When the wire rod 56 is connected and fixed by a pile driven directly into the ground, a mortar or the like can be poured and hardened around it to protect it into a spherical shape or a conical shape.

図６の実施形態において、６６は支柱、６７はフランジ、６８はコンクリート基礎、７１はアンカー（ボルト）であり、この場合、アンカー７１は上に短いものでなくロングボルトによりなり、これらが支柱６６の外周を囲うようにして防護を構成するものにしてある。これらアンカー７１は相互に連結材６９で結合してもよいし、その内周空間に廃タイヤなどの緩衝材やコンクリートなどを投入保持するようにしてもよい。アンカー７１は高ナットで上下を連結してもよい。尚、仮想線７０は地盤で、支柱６６の基部がこの地盤７０と同等の高さである場合と地盤７０の中に低い埋設される場合とがあることを示している…Ａ。 In the embodiment of FIG. 6, 66 is a support, 67 is a flange, 68 is a concrete foundation, and 71 is an anchor (bolt). In this case, the anchor 71 is not a short top but a long bolt. The protection is configured so as to surround the outer periphery. These anchors 71 may be coupled to each other by a connecting material 69, or buffer materials such as waste tires, concrete, or the like may be input and held in the inner circumferential space thereof. The anchor 71 may be connected up and down with a high nut. The virtual line 70 is the ground, and indicates that the base of the support 66 may be as high as the ground 70 or embedded in the ground 70 at a low level.
