〔発明の技術分野〕
この発明は、道路や鉄道線路沿いに切立つ崖の傾斜面に
設けて、落石による不測の被害を未然に防止する吊式落
石防止柵に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a hanging rockfall prevention fence that is installed on the slope of a steep cliff along a road or railway track to prevent unexpected damage from falling rocks.
〔発明の技術的背景とその問題点）
崖際に隣接する道路や鉄道線路には、その崖からの落石
により不測の被害を蒙る危険があり、このため一般にこ
のような箇所においては、崖の傾斜面下方部に落石防止
柵を設け、この防止柵で落石を受止めて被害の発生を防
止するようにしている。[Technical background of the invention and its problems] Roads and railroad tracks adjacent to cliffs are at risk of suffering unexpected damage from falling rocks from the cliffs. A rockfall prevention fence is installed at the lower part of the slope to catch falling rocks and prevent damage.
ところが、従来のこの種の落石防止柵は、傾斜面の地盤
に直接建て込む剛体構造のものであり、このため落石時
のＷｉｓがそのまま柵全体に加わり、したがって比較的
早期に破損し、耐久性の点で難点があり、また施工に当
たって、いちいち傾斜面の地盤にコンクリート等でその
構築用の基礎を築かなくてはならないから、作業に手間
が掛かるとともに、費用が嵩んでしまう。さらに、防止
柵の内側に落石や土砂が堆積した際に、その廃棄が相当
面倒となり、しかも一旦設置してしまうとその移設が不
可能になるという問題があった。However, conventional rockfall prevention fences of this type have a rigid structure that is built directly into the ground on a slope, and as a result, the Wis from falling rocks is directly applied to the entire fence, which causes it to break relatively quickly and reduce its durability. Moreover, during construction, the foundation for the construction must be built with concrete etc. on the ground of the slope, which makes the work time-consuming and increases the cost. Furthermore, when falling rocks or earth and sand accumulate inside the prevention fence, there is a problem in that it becomes quite troublesome to dispose of it, and furthermore, once it is installed, it is impossible to relocate it.
この発明はこのような点に着目してなされたもので、そ
の目的とするところは、耐久性に優れ、施工が簡単で、
ざらに落石や土砂の廃棄を容易に行なえ、しかも必要に
応じて他の箇所への移設や撤去も容易に行なうことがで
きる吊代落石防止柵を提供することにある。This invention was made with attention to these points, and its purpose is to have excellent durability, easy construction,
To provide a hanging rock fall prevention fence which can easily dispose of fallen rocks and earth and sand, and can also be easily moved to another location or removed as required.
すなわちこの発明は、欄フレームに金網を張設して柵体

体で落石を受止めるようにしたものである。That is, in this invention, a fence body is constructed by stretching a wire mesh on a parapet frame, and this fence body is installed almost at right angles to the slope of a cliff so as to be able to slide freely, and furthermore, the fence body is installed from the top and bottom of the fence body, respectively. A support wire rope is led out, the suspension wire rope is lowered from the top of the slope, the support wire rope is connected to the suspension wire rope to support the fence body, and the fence body receives falling rocks. It was meant to be stopped.

用意な倒伏が防止される。Therefore, if a rock falls from the upper end side of the slope 10, it will be caught by the fence 1 while moving along the slope 10. At this time, since the fence body 1 is supported in a suspended state by the support wire ropes 9... and the hanging wire ropes 12... ..., 8..., and slides slightly downward through the supporting wire ropes 9... and the suspending wire ropes 12...
- Elastic elongation occurs, and this elastic elongation alleviates the impact on the fence 1, thereby preventing damage to the fence 1 and improving durability. In addition, there is a risk that fence body 1 will shake due to falling rocks, but this fence body 1 has support 7
... are provided, and these supports 7 ... serve as a support plate 8.
Since it is in contact with the inclined surface 10 through..., it is prevented from falling down inadvertently.

。Furthermore, such a rock fall prevention fence is not built into the ground, but has a structure in which the fence body 1 installed on the slope 10 is simply supported by the supporting wire ropes 9 and the hanging wire loafs 12. , construction is simple and extremely advantageous both in terms of work and economy. When falling rocks or dirt accumulate inside the fence 1, it can be easily disposed of by lifting the fence 1 with a crane or the like and lifting its lower edge off the slope 10. Further, the fence body 1 can be easily removed or relocated to another location if necessary.
なお、この落石防止柵は、５以外の落下物、或いは雪崩
に対しても有効に作用する。It should be noted that this rockfall prevention fence effectively acts against falling objects other than 5 or avalanches.
以上説明したように、この発明によれば、支持ワイヤロ
