Description

【考案の詳細な説明】[Detailed description of the device] 【産業上の利用分野】[Industrial applications]

本考案は雪崩防止のために斜面に設置される雪崩防止杭に関わるものである。 The present invention relates to an avalanche prevention pile installed on a slope to prevent an avalanche.

【従来の技術】[Prior art]

雪崩予防杭は樹木が茂った斜面では雪崩が起きないことから考案された、斜面に直角に設置される杭状構造物であり、集合的に用いられる。斜面への配置法は千鳥配置とし、３５〜４０度の斜面では杭間の水平距離は５ｍ、列間斜距離は８ｍ程度が標準とされる。その構造は単独柱のものと杭本体を谷側に設けた控柱で支持する２通りの方法が採用されている。基礎はコンクリート基礎または根かせが採用されている。 The avalanche prevention pile is a pile-like structure installed at right angles to the slope, which was devised because an avalanche does not occur on a forested slope and is used collectively. The staggered layout method is staggered, and the standard horizontal distance between piles is 5 m and the diagonal distance between rows is approximately 8 m on a slope of 35-40 degrees. As for the structure, there are two types of methods: one with a single pillar and the other with the main body of the pile supported by a retaining pillar installed on the valley side. The foundation is concrete foundation or skein.

【考案が解決しようとする課題】[Problems to be solved by the device]

現状の雪崩防止杭には以下に述べるような問題がある。法面に無機的な杭状構造物が林立するので、景観上好ましくない。単一な杭状構造物である従来の雪崩防止杭は全層雪崩の防止が対象であり、表層雪崩に関しては何らその効果が期待できない。標準の設計法では１本の雪崩防止杭は水平距離分の雪圧を受けると考えて計算を行うので、多雪地では基礎、部材が共に大きなものになる。そのとき、谷側に控柱を設ける方法もあるが、法面上にさらに部材が多数見えるので景観上好ましくない。現在、雪崩防止杭に用いられているコンクリート基礎、根かせは共に施工時に法面の掘削を伴うので、法面を荒らし、崩落の危険が増大する。本考案は以上のような従来の雪崩防止杭の欠点をなくし、景観的に異和感を与えず、施工のときに法面を荒らさない強度的に優れた雪崩防止杭を提供するものである。 The current avalanche prevention pile has the following problems. Inorganic pile-like structures are lined up on the slope, which is not desirable for the landscape. The conventional avalanche prevention pile, which is a single pile-like structure, is intended to prevent all-layer avalanche, and no effect can be expected for surface avalanche. In the standard design method, one avalanche prevention pile is calculated on the assumption that it receives the snow pressure for the horizontal distance, so the foundation and the members will be large in a snowy area. At that time, there is also a method of providing support pillars on the valley side, but it is not preferable for the landscape because more members can be seen on the slope. At present, both concrete foundations and skeins used for avalanche prevention piles involve excavation of slopes during construction, which damages the slopes and increases the risk of collapse. The present invention eliminates the above-mentioned drawbacks of conventional avalanche prevention piles, provides an avalanche prevention pile with excellent strength that does not give a strange feeling to the landscape and does not roughen the slope during construction. is there.

【課題を解決するための手段】[Means for Solving the Problems]

本体幹材から枝材を多段にわたって放射状に斜め上方に張り出させ、人工樹木風な立体構造物とする。本体幹材の下部は穿孔打設した本体側基礎杭に連結させる。法面上で雪崩防止杭本体の位置から山側上方に控側基礎杭を穿孔打設し、控側基礎杭上部に固定した控ワイヤーロープで本体幹材の頂部から適宜距離を置いた位置で本体幹材を支持させる。本体側、控側基礎に杭基礎を採用し、施工による斜面の荒れを最小にする。 The branch material is projected radially upward from the main trunk material in multiple stages to form an artificial tree-like three-dimensional structure. The lower part of the trunk of the main body is connected to the foundation piles on the main body side that are punched. On the slope, a backing foundation pile is pierced from the position of the avalanche prevention pile main body to the mountain side above, and the main body is placed at an appropriate distance from the top of the main trunk material with a holding wire rope fixed to the top of the backing foundation pile. Support trunk material. Pile foundations are used for the main body side and the back side foundation to minimize the roughness of the slope due to construction.

【作用】[Action]

本体幹材から張り出させた各枝部も雪の移動を防止する。また、基礎杭は穿孔や打設によって施工するので斜面を荒らさない。本体側、控側共に基礎として杭を用いているので、荷重によりある程度自由に変位することが出来る。本体幹材の頂部から適宜離れた位置を控ワイヤーロープで支持するので、本体幹材に作用する雪圧による曲げモーメントを大幅に低減させる。 The branches that extend from the main trunk also prevent the movement of snow. In addition, the foundation piles will be constructed by drilling and placing, so the slope will not be roughened. Since piles are used as foundations on both the main body side and the back side, they can be displaced to some extent by the load. Since the wire rope is supported at a position that is appropriately separated from the top of the main trunk material, the bending moment due to the snow pressure acting on the main trunk material is greatly reduced.

【実施例】【Example】

本考案の実施例を図面に基づいて説明する。図１は本考案の雪崩防止杭を法面に設置したときの側面図である。雪崩防止杭本体１は鋼管で構成した本体幹材２から同様に鋼管で構成した本体枝材３を多段にわたって放射状に斜め上方に張り出させて一体構造としたものである。基礎は本体側、控側共に基礎杭とする。その際、雪崩防止柵のアンカーとして多用されている、杭自体に先端ビット７が付いていて、それを旋回掘進させてそのまま杭とするものを使用すると施工が容易になる。雪崩防止杭本体１の本体側基礎杭４への固定には連結パイプ５を介してボルトナット８で行う。雪崩防止杭本体１の山側上方の適切な位置に同様に控側基礎杭６を打設し、控ワイヤーロープ９を控側基礎杭６の上端に固定し、それを雪崩防止杭の本体幹材２の上端から適切な位置に結び付け支持させる。 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view when the avalanche prevention pile of the present invention is installed on the slope. The avalanche prevention pile main body 1 has a one-piece structure in which a main body trunk member 2 made of a steel pipe and a main body branch member 3 made of a steel pipe are radially and diagonally extended in multiple stages. The foundation will be foundation piles on both the main body side and the back side. At this time, the pile itself, which is often used as an anchor for an avalanche prevention fence, has a tip bit 7 attached to it, which can be swiveled to form a pile as it is. The avalanche prevention pile main body 1 is fixed to the main body side foundation pile 4 with the bolt nut 8 through the connecting pipe 5. In the same way, a backing foundation pile 6 is laid at an appropriate position above the mountain side of the avalanche prevention pile main body 1, and a backing wire rope 9 is fixed to the upper end of the backing foundation pile 6, which is used as a main trunk material of the avalanche prevention pile. The upper end of 2 is tied and supported at an appropriate position.

【考案の効果】[Effect of device]

本考案の雪崩防止杭は以上のような構成であり、以下に示すような効果がある。本体幹材に放射状に枝部が配置されているので、従来の単純な支柱状の雪崩防止杭に較べて、斜面積雪の移動をより効果的に押さえることが出来、雪崩防止効果が高い。また、人工樹木風の外観であるので景観上好ましい効果がある。その際、ＦＲＰコーティングなどにより表面に擬木的な塗装処理を施せばより効果的である。本体幹材が本体側基礎杭と控側基礎杭に結び付けられたワイヤーロープの２点で支持されているので、従来の単支柱的な雪崩防止杭で対応できないような積雪深の場所でも適用することが出来る。また同じ積雪深ならより小さな断面の材料で済む。なお控柱を付けた雪崩防止杭でも同様な効果が期待出来るが、ワイヤーロープに較べてはるかに目に付く断面の大きい控柱が必要であり、しかも目立ち易い本体の谷側に控柱が位置するので景親上、極めて都合が悪い。法面の不整などで側圧が作用した場合でも基礎杭の場合は柔軟に変位し、雪崩防止杭本体材料に無理が掛かりにくい。また、コンクリート基礎や根かせを使用しないので法面を荒らさない、また特にコンクリート基礎に較べて目立たないので景観上好ましい。 The avalanche prevention pile of the present invention is configured as described above and has the following effects. Since the branches are radially arranged on the trunk of the main body, the movement of snow on sloping areas can be suppressed more effectively compared to the conventional simple pillar-shaped avalanche prevention piles, and the avalanche prevention effect is high. . In addition, the appearance of an artificial tree has a favorable effect on the landscape. At that time, it is more effective if the surface is coated with a pseudo-wood like FRP coating. Since the trunk material of the main body is supported at two points of the wire rope connected to the main body side foundation pile and the holding side foundation pile, it can be applied even in deep snow areas where conventional avalanche avalanche prevention piles cannot handle. You can If the snow depth is the same, a material with a smaller cross section will suffice. A similar effect can be expected with an avalanche prevention pile with retaining columns, but a retaining column with a much larger cross section than a wire rope is required, and the retaining column is located on the valley side of the main body where it is easily noticeable. It is extremely inconvenient because of the fact that it does. Even if lateral pressure is applied due to irregular slopes, the foundation pile will be displaced flexibly, and it will be difficult for the material of the avalanche prevention pile body to be forced. In addition, since it does not use concrete foundations or skeins, it does not roughen the slope, and it is particularly unobtrusive compared to concrete foundations, which is preferable for the landscape.
