Description
本考案は崩壊や道路開設等で生じた裸地斜面の自然景観復元を図るための飛来種子捕捉部材および構造体に関するものである。 The present invention relates to a flying seed capturing member and a structure for restoring a natural landscape of a bare slope caused by collapse or road establishment.
山間部の崩落地や道路開設により生じた裸地斜面（法面）を現地の樹木等が生産する種子の飛来により緑化を図る場合、雨水等による流下水やそれに伴う表層土砂の移動等が生じるため、種子を斜面に定着させることが困難となっている。このような飛来種子の流亡を防ぐため、斜面にステップを造成する方法が知られている。 When planting bare land slopes (slopes) caused by the collapse of mountainous areas and roads by the seeds produced by local trees, etc., sewage due to rainwater, etc., and the movement of surface soil associated with it occur. Therefore, it is difficult to fix seeds on the slope. In order to prevent such flying seeds from flowing away, a method of creating steps on the slope is known.
上記の方法は、クリンプ金網や溶接金網あるいはプラスチック成型品等による生育基盤保持具を斜面に設置し、現地発生土等の生育基盤を覆土することで飛来種子が定着するための平地を作るものであるが、生育基盤保持具の設置箇所はフラットな面である必要があり、凹凸のある斜面では、人力または機械により斜面表面をフラットに仕上げなければならず施工性が低下する場合がある。また、覆土の作業を斜面で実施することは容易ではなく、生育基盤の運搬等も考慮すると施工性は劣る。 In the above method, a growth base holder made of crimped wire mesh, welded wire mesh, plastic molding, etc. is installed on the slope, and the ground is set up by covering the growth base such as locally generated soil. However, the installation location of the growth base holder needs to be a flat surface, and on an uneven slope, the slope surface must be finished flat by human power or a machine, and workability may be reduced. Moreover, it is not easy to carry out the soil covering work on the slope, and the workability is inferior considering the transportation of the growth base and the like.
本考案は上記の事柄に留意してなされたもので、その目的は、凹凸のある斜面でも容易に飛来種子を捕捉する箇所を造成し、それらの種子の発芽・生育を促進する環境を整えることで裸地斜面の自然景観復元に寄与する飛来種子捕捉部材および構造体を提供することである。 The present invention has been made in consideration of the above-mentioned matters, and its purpose is to create a place where trapped flying seeds are easily captured even on uneven slopes, and to prepare an environment for promoting germination and growth of those seeds. It is to provide flying seed capture members and structures that contribute to the natural landscape restoration of bare slopes.
上記目的を達成するために、本考案に係る飛来種子捕捉部材は、複数の棒状体を結合具を用いて連結し、その連結箇所を屈曲可能な構造とすることを特徴とする。（請求項１） In order to achieve the above object, the flying seed catching member according to the present invention is characterized in that a plurality of rod-like bodies are connected using a coupler and the connecting portion is bent. (Claim 1)
さらに、上記目的を達成するために、本考案に係る飛来種子捕捉構造体は、前記飛来種子捕捉部材を、長手方向が等高線と平行になるように斜面に設置することにより形成される。（請求項２） Furthermore, in order to achieve the said objective, the flying seed capture | acquisition structure which concerns on this invention is formed by installing the said flying seed capture | acquisition member in a slope so that a longitudinal direction may become parallel to a contour line. (Claim 2)
この考案における斜面とは、例えば法面等の植物を植生しようとする斜面を意味する。また、斜面は、その表面に植生面を有していてもよい。 The slope in this device means a slope on which a plant such as a slope is vegetated. Moreover, the slope may have a vegetation surface on the surface.
前記植生面は、例えば、斜面の表面に肥料、保水材、土壌改良材の少なくとも一つを用いた植生基材からなる植生基盤層を造成したものである。なお、前記植生面は、上記の構成からなるものに限られず、例えば、現地周辺の土壌などの種子を含む客土を用いてもよい。さらに、前記植生面は、例えば、斜面の表面に植生シートや植生マット及び前記植生基材を収容した土のうを敷設することによって形成してもよい。 For example, the vegetation surface is formed by forming a vegetation base layer made of a vegetation base material using at least one of a fertilizer, a water retention material, and a soil improvement material on the surface of a slope. In addition, the said vegetation surface is not restricted to what consists of said structure, For example, you may use the guest soil containing seeds, such as the soil around a field. Furthermore, the vegetation surface may be formed, for example, by laying a vegetation sheet, a vegetation mat, and a sandbag containing the vegetation base material on the surface of the slope.
前記飛来種子捕捉部材は、複数の棒状体を、例えばボルトナット等の結合具を用いて連結し、その連結箇所を屈曲可能な構造としたものである。 The flying seed catching member has a structure in which a plurality of rod-like bodies are connected using a coupler such as a bolt and nut, and the connecting portion can be bent.
上記の構成からなる本考案によれば、凹凸のある斜面でも容易に飛来種子を捕捉する箇所を造成し、それらの種子の発芽・生育を促進する環境を整えることで裸地斜面の自然景観復元に寄与することが可能になる。 According to the present invention configured as described above, a natural landscape restoration of a bare slope can be achieved by creating a place where trapped seeds can be easily captured even on uneven slopes and preparing an environment that promotes germination and growth of those seeds. It becomes possible to contribute to.
すなわち、前記飛来種子捕捉部材が複数の棒状体の連結箇所を屈曲可能な構造であることから、斜面の凹凸に沿うように設置することができ、棒状体と斜面により作られる凹部に飛来種子を捕捉することができる。 That is, since the flying seed capturing member has a structure that can bend the connecting portion of a plurality of rod-shaped bodies, it can be installed along the irregularities of the slope, and the flying seeds can be placed in the recesses formed by the rod-shaped body and the slope. Can be captured.
また、森林の地上面では倒れた古木を礎にして新たな世代の木が育つ倒木更新が見られるが、これは、倒木自身が養分の供給源となり、また、適度な湿度を有しているためである。このことから、特に前記飛来種子捕捉部材を木製とした場合には、倒木更新と同様に養水分の供給の面で有利に働き、捕捉した種子の発芽・生育を促進する環境を整えることができる。 In addition, there is a renewal of fallen trees where a new generation of trees grows based on fallen old trees on the ground surface of the forest, but this is the source of nutrients for the fallen trees themselves and has moderate humidity Because. For this reason, particularly when the flying seed capturing member is made of wood, it can work in an advantageous manner in terms of the supply of nourishing moisture as in the case of fallen tree renewal, and an environment for promoting germination and growth of the captured seed can be prepared. .
