Description

この発明は、火山に設置されて噴火時に噴石から登山者を防護する噴石シェルターに関する。   The present invention relates to a cinder shelter that is installed in a volcano and protects climbers from cinders during an eruption.

平成２６年９月２７日の御嶽山の噴火は、多数の死傷者を出す戦後最悪の火山災害となった。多くの死因は、飛んできた噴石の直撃による損傷死であった。もし御嶽山に、噴石から身を守ることのできる噴石シェルターが存在していれば、多くの登山者が助かった可能性がある。しかしながら、ある調べによれば、飛んでくる噴石から登山者の身を守る噴石シェルターを設置している国内の活火山は、気象庁の常時監視対象４７火山のうち、草津白根山（群馬・長野）、浅間山（群馬・長野）、阿蘇山（熊本）など１０火山にとどまっている。特に昨今、我が国最大の火山である富士山の噴火の可能性が議論されており、もし登山シーズン中に富士山が噴火することがあれば、その被害は御嶽山とは比べものにならないくらい大きなものになることが予想される。実際に、富士山には噴石から身を守ることのできる噴石シェルターは設置されていない。   The eruption of Mt. Ontake on September 27, 2014 was the worst post-war volcanic disaster that caused many casualties. Many causes of death were deaths from direct hits of flying cinders. If Mt. Ontake has a cinder shelter that can protect itself from cinders, many climbers may have helped. However, according to one study, the active volcano in Japan, which has a cinder shelter that protects climbers from flying volcanic blocks, is one of 47 volcanoes that are constantly monitored by the Japan Meteorological Agency. Mt. Asama (Gunma / Nagano), Mt. Aso (Kumamoto), etc. In particular, the possibility of the eruption of Mt. Fuji, Japan's largest volcano, has been discussed recently, and if Mt. Fuji erupts during the mountain climbing season, the damage will be as great as that of Mt. Ontake. It is expected that. In fact, Mt. Fuji does not have a cinder crest that can protect itself from cinders.

火山に設けられて噴石から登山者の身を守るものではないが、雪崩やがけ崩れ等から道路や鉄道を防護するためのシェルターが特許文献１に記載されている。このシェルターはアーチ型の形状を有している。このシェルターは、シェルターを構築するための曲面板状のセグメントをクローラークレーンで吊り込み、支持台車がこのセグメントを下から支持するとともに支持台車からセグメントの内側部の作業を行い、セグメントの外側部の作業を作業台車から行い、クローラークレーンと、支持台車と、作業台車とを移動させながらセグメントを吊り込むとともにセグメントどうしを接合することで構築することができる。現在火山に設けられている噴石シェルターにもアーチ型のものが存在する。   Patent Document 1 describes a shelter for protecting roads and railways from avalanches and landslides, although it is not provided to protect climbers from volcanic blocks provided at volcanoes. The shelter has an arch shape. In this shelter, a curved plate-like segment for constructing a shelter is suspended by a crawler crane, the support carriage supports this segment from below, and the inside of the segment is operated from the support carriage. The work can be performed from the work cart, and the segments can be suspended while the crawler crane, the support cart, and the work cart are moved, and the segments can be joined together. There is also an arch type cinder in the volcano shelter.

特開平６−１２８９１３号公報JP-A-6-128913

しかしながら、特許文献１に記載のシェルターを火山に設置しようとすると、曲面板状のセグメントを火山の設置場所まで搬送するだけではなく、クローラークレーンと、支持台車と、作業台車とを同場所まで移動しなければならず、設置準備が大掛かりになるといった問題点があった。また、火山の設置場所は通常、斜面が多く足場も悪いため、現場作業が煩雑になるといった問題点もあった。   However, when the shelter described in Patent Document 1 is to be installed on a volcano, not only the curved plate-shaped segment is transported to the volcano installation location, but also the crawler crane, support cart, and work cart are moved to the same location. There is a problem that preparation for installation becomes large. In addition, the location where the volcano is installed usually has many slopes and poor scaffolding, so there is a problem that the work at the site becomes complicated.

この発明はこのような問題点を解決するためになされたもので、簡単に設置できる噴石シェルターを提供することを目的とする。   The present invention has been made to solve such problems, and an object of the present invention is to provide a cinder block shelter that can be easily installed.

この発明に係る噴石シェルターは、複数の曲面板状の鋳物製のセグメントを、それらの湾曲方向に隣接して並べてアーチ型に設置し、隣接するセグメント同士を接合させて構成したものである。   The cinder crusher according to the present invention is constructed by arranging a plurality of curved plate-like cast segments adjacent to each other in the curve direction and installing them in an arch shape, and joining the adjacent segments together.

この発明によれば、複数の曲面板状の鋳物製のセグメントを、それらの湾曲方向に隣接して並べてアーチ型に設置し、隣接するセグメント同士を接合させて構成されていることにより、曲面板状のセグメントを設置場所まで搬送すればよく、それらを組み立てる際にも特別な装置が必要ないので、噴石シェルターを簡単に設置することができる。   According to the present invention, a plurality of curved plate-shaped casting segments are arranged adjacent to each other in the curve direction and installed in an arch shape, and the adjacent segments are joined to each other to thereby form a curved plate. It is only necessary to transport the segment to the installation location, and no special equipment is required when assembling them, so the cinder crest can be easily installed.

以下、この発明の実施の形態を添付図面に基づいて説明する。
図１に示されるように、噴石シェルター１は、複数の曲面板状のセグメント２を、それらの湾曲方向に隣接して並べてアーチ型に設置し、隣接するセグメント２同士を、図示しないボルトで接合させて構成されている。複数のセグメント２のうち、アーチ型の両端に位置するセグメントはそれぞれ、公知の技術で地面８に固定された土台９に、図示しないボルトで接合されている。噴石シェルター１の内部の空間に登山者が避難することにより、火山で噴火が起こった時に、各セグメント２が登山者を噴石から防護することができる。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the cinder crusher 1 has a plurality of curved plate-like segments 2 arranged adjacent to each other in the curved direction and installed in an arch shape, and the adjacent segments 2 are joined together by bolts (not shown). Is configured. Of the plurality of segments 2, the segments positioned at both ends of the arch shape are joined to a base 9 fixed to the ground 8 by a known technique with bolts (not shown). By evacuating the climber to the space inside the cinder 1, each segment 2 can protect the climber from the cinder when an eruption occurs at the volcano.

図２に示されるように、各セグメント２は、矩形の形状を有しており、その長手方向に延びる図示しない軸に関して湾曲した曲面板状の形状を有している。各セグメント２は、その周縁部に沿って設けられた周縁リブ部３を有している。周縁リブ部３は、互いに平行な一対の第１周縁リブ部３ａ，３ａと、第１周縁リブ部３ａと垂直な方向に延び第１周縁リブ部３ａよりも短い、互いに平行な一対の第２周縁リブ部３ｂ，３ｂとから構成されている。また、各セグメント２は、第１周縁リブ部３ａが延びる方向に関して中央の位置に、一端が一方の第１周縁リブ部３ａに接続されるとともに他端が他方の第１周縁リブ部３ａに接続されるように設けられた中央リブ部４を有している。   As shown in FIG. 2, each segment 2 has a rectangular shape, and has a curved plate shape that is curved with respect to an axis (not shown) extending in the longitudinal direction. Each segment 2 has a peripheral rib portion 3 provided along the peripheral portion thereof. The peripheral rib portion 3 includes a pair of first peripheral rib portions 3a and 3a parallel to each other and a pair of second peripheral ribs extending in a direction perpendicular to the first peripheral rib portion 3a and shorter than the first peripheral rib portion 3a. It is comprised from the peripheral rib part 3b, 3b. Each segment 2 is connected to the first peripheral rib portion 3a at one end and connected to the first peripheral rib portion 3a at the other end at the center position in the extending direction of the first peripheral rib portion 3a. The central rib portion 4 is provided as described above.

図３に示されるように、各第１周縁リブ部３ａには、４つのボルト孔５が形成されている。複数のセグメント２をそれらの湾曲方向に隣接して並べてアーチ型に設置すると、隣り合うセグメント２の第１周縁リブ部３ａ同士が接する状態となるが、互いに接する第１周縁リブ部３ａのそれぞれに形成された４つのボルト孔５はそれぞれ重なり合う。重なり合ったボルト孔５に、図示しないボルトを挿入してナットで締め付けることにより、隣り合うセグメント２同士が互いに接合される。   As shown in FIG. 3, four bolt holes 5 are formed in each first peripheral rib portion 3a. When a plurality of segments 2 are arranged adjacent to each other in the bending direction and installed in an arch shape, the first peripheral rib portions 3a of the adjacent segments 2 are in contact with each other, but each of the first peripheral rib portions 3a that are in contact with each other The formed four bolt holes 5 overlap each other. Adjacent segments 2 are joined together by inserting bolts (not shown) into the overlapping bolt holes 5 and tightening them with nuts.

また、図１に示されるように、各第２周縁リブ部３ｂにも、２つのボルト孔６が形成されている。第２周縁リブ部３ｂ同士が接するように２つのセグメントを隣接させると、第２周縁リブ部３ｂのそれぞれに形成された２つのボルト孔６はそれぞれ重なり合う。重なり合ったボルト孔６に、図示しないボルトを挿入してナットで締め付けることにより、隣り合うセグメント２同士が互いに接合される。これにより、噴石シェルター１の軸方向の長さを調節することができる。   Moreover, as shown in FIG. 1, two bolt holes 6 are also formed in each second peripheral rib portion 3b. When the two segments are adjacent to each other so that the second peripheral rib portions 3b are in contact with each other, the two bolt holes 6 formed in each of the second peripheral rib portions 3b overlap each other. Adjacent segments 2 are joined together by inserting bolts (not shown) into the overlapping bolt holes 6 and tightening them with nuts. Thereby, the length of the axial direction of the cinder 1 can be adjusted.

セグメント２は、飛んできた噴石が衝突しても破壊しない材質で形成する必要がある。そのような材質としては、鉄、コンクリート、鋳物等が挙げられが、形状生産性及び量産効果の良い鋳物が好ましい。   The segment 2 needs to be formed of a material that does not break even when the flying cinder collides. Examples of such a material include iron, concrete, castings, and the like, but castings having good shape productivity and mass production effects are preferable.

噴石シェルター１を火山の噴火口近辺に設置する際には、まず必要な枚数のセグメント２及び土台９を火山の麓に搬送しておき、ヘリコプターでセグメント２及び土台９を設置場所に搬送する。設置場所での噴石シェルター１の組み立ては、特別な装置を使わずに作業員が手作業で行えるので、必要な資材の搬送及び噴石シェルター１の組み立てを簡単に行うことができる。   When the cinder shelter 1 is installed in the vicinity of the volcano crater, the necessary number of segments 2 and bases 9 are first transported to the volcano base, and the segments 2 and base 9 are transported to the installation site by a helicopter. Assembling of the cinder crusher 1 at the installation site can be performed manually by a worker without using a special device, so that necessary materials can be transported and the cinder crusher 1 can be easily assembled.

このように、複数の曲面板状のセグメント２を、それらの湾曲方向に隣接して並べてアーチ型に設置し、隣接するセグメント２同士を接合させて構成されていることにより、曲面板状のセグメント２を設置場所まで搬送すればよく、それらを組み立てる際にも特別な装置が必要ないので、噴石シェルターを簡単に設置することができる。   In this way, a plurality of curved plate-like segments 2 are arranged adjacent to each other in the bending direction and installed in an arch shape, and the adjacent segments 2 are joined to each other, thereby forming a curved plate-like segment. 2 need only be transported to the installation location, and no special equipment is required when assembling them, so that the cinder crusher can be easily installed.

尚、噴石シェルター１の内部の空間の半径は、セグメント２が湾曲する曲率半径を調節することにより、任意に変更することができる。   Note that the radius of the space inside the cinder 1 can be arbitrarily changed by adjusting the radius of curvature at which the segment 2 is curved.

この実施の形態では、第１周縁リブ部３ａに４つのボルト孔５が設けられるとともに第２周縁リブ部３ｂに２つのボルト孔６が設けられていたが、それぞれのボルト孔の個数は任意に変更可能である。尚、ボルト孔６はなくてもよい。   In this embodiment, four bolt holes 5 are provided in the first peripheral rib portion 3a and two bolt holes 6 are provided in the second peripheral rib portion 3b. However, the number of each bolt hole is arbitrary. It can be changed. The bolt hole 6 may not be provided.

１ 噴石シェルター、２ セグメント。   1 Cinder crest, 2 segments.
