Description

【0001】
【発明の属する技術分野】
この発明は、法面など傾斜面の緑化方法に関する。
【0002】
【従来の技術】
【特許文献1】特開2002−332624号公報
近年、生物の多様性、遺伝子攪乱防止などへの配慮から、緑化施工地周辺の植物を使用することへの要望が高まっており、施工地周辺の種子を採取して用いたり、施工地周辺の表層土壌や施工地周辺の森林内からそこに生育する植物の種子を埋土種子として含む表土シードバンクを採取して、この表土シードバンクを緑化方法に使用する傾向が高まって、それが実施されつつある。
【0003】
【発明が解決しようとする課題】しかしながら、上記表土シードバンクを活用する緑化方法において、緑化対象面である法面など傾斜面を吹き付け等によって全面を緑化を行おうとすると、その吹き付け等のために採取する表土の量が多くなりそれだけ周囲環境に与える影響が大きくなるとともにコスト高となる。また、目的とする木本類の侵入が遅れるといった問題がある。
【0004】この発明は、上述の事柄に留意してなされたもので、その目的は、緑化対象面の周囲環境に悪影響を与えることなく、これとマッチした緑化を安価かつ確実に行うことができ、自然度の高い緑化を行うことのできる傾斜面の緑化方法(以下、単に緑化方法という)を提供することである。
【0005】
【課題を解決するための手段】上記目的を達成するため、この発明の緑化方法は、緑化対象である傾斜面に、鞘部を備えた植生ネットを敷設した後、前記鞘部に適宜高さの補強部材を挿入して前記鞘部および補強部材によって適宜高さかつ前記傾斜面の等高線に平行な植生基材受け部を形成し、この植生基材受け部の上方側の傾斜面に表土シードバンクを含んだ植生基材を吹き付けることを特徴としている(請求項1)。
【0006】また、この発明の緑化方法は、緑化対象である傾斜面に、鞘部に適宜高さの補強部材を予め挿入してある植生ネットを敷設して、前記鞘部および補強部材によって適宜高さかつ前記傾斜面の等高線に平行な植生基材受け部を形成し、この植生基材受け部の上方側の傾斜面に表土シードバンクを含んだ植生基材を吹き付けることを特徴としている(請求項2)。
【0007】上記いずれの緑化方法においても、緑化対象面(または施工対象面)である傾斜面に、植生ネットの一部に形成された鞘部および補強部材による植生基材受け部が適宜の間隔をおいて適宜高さかつ等高線に平行になるように形成されるので、この植生基材受け部の上方側の傾斜面に表土シードバンクを含んだ植生基材を吹き付けることによって、前記傾斜面に等高線に平行になるように複数の植生帯が形成される。そして、これらの植生帯以外の傾斜面は人工的な裸地となっており、周辺から植物種子が入り易く、植生の遷移が促進され、自然度の高い緑化を行うことができる。そして、表土シードバンクを含んだ植生基材を、傾斜面全体に吹き付けるのではなく、前記傾斜面に点在するように形成される植生基材受け部の上方側の傾斜面にのみ吹き付けるだけでよいので、表土の採取量が少なくて済み、周囲環境に及ぼされる悪影響がほとんど無いとともにコスト安に施工することができる。また、前記傾斜面に植生基材が吹き付けられることによって形成される複数の植生帯によって前記裸地の保水性が向上し、余所から飛来してきた種子の発芽が促進される。
【0008】そして、前記補強部材として金網やプラスチック網などの網体を用いた場合(請求項3)、補強部材として軽量なものが得られるとともに、傾斜面の凹凸に応じてその形状を適宜変形することができ、設置部分の隙間を可及的に小さくすることができる。そして、この網体としては市販のものを用いることができるので、施工コストを低く抑えることができるとともに、植生ネットが設けられているので、前記網体の目合いを大きくしても、吹き付けられた植生基材の流亡が巧みに防止できる。
【0009】また、上記目的を達成するため、この発明の緑化方法は、緑化対象である傾斜面に、植生ネットを、前記傾斜面の等高線に平行な鞘部が形成されるようにして敷設し、前記鞘部の最上位を、前記傾斜面の等高線に平行に保持された持ち上げ部材によって持ち上げて植生基材受け部を形成し、この植生基材受け部の上方側の傾斜面に表土シードバンクを含んだ植生基材を吹き付けることを特徴としている(請求項4)。
【0010】このようにした場合においても前記請求項1または2に記載の緑化方法と同様の作用効果が得られるとともに、さらに、植生ネットそのものが植生基材受け部を構成するので、植生基材受け部の構成が簡素であり、施工コストがより安価となる。
【0011】そして、植生ネットに肥料袋を装着しておけば(請求項5)、植物の遷移がより促進される。
【0012】
【発明の実施の形態】以下、この発明の詳細を、図を参照しながら説明する。図1〜図3は、この発明の第1の実施の形態を示すものである。まず、図1および図2において、1は緑化対象面としての傾斜面で、例えば、法面である。2はこの法面1の上面に敷設される植生ネットで、この植生ネット2上には法面1の等高線と平行に複数の植生基材受け部3が適宜の間隔をおいて形成されており、各植生基材受け部3の上方側の法面1には植生基材4が吹き付けられて、複数の植生帯5が形成されている。そして、6は植生基材受け部3を植生ネット2の一部と構成する補強部材7(後述する)を所定の姿勢に保持するアンカーピン、8は植生ネット2に付設される肥料袋、9は植生基材吹付け機(図示していない)の吹付けノズルである。
【0013】前記植生ネット2は、適宜の素材によって適宜の目合いを有するように、例えば、図3に示すように、平面視長方形に編組されている。そして、この植生ネット2の表面には、その長手方向をY、短手方向をXとするとき、補強部材7を収容する高さが例えば10cm程度の複数の鞘部10と、肥料袋8を収容する肥料袋収納部11とが適宜の間隔をおいて前記X方向に形成されている。
【0014】そして、前記植生基材4は、表土シードバンクを含んだものよりなり、より具体的には、前記法面1の近傍の地山や森林等の表土(植物種子12を含んでいる)にピートモスやバーク堆肥や保水材など生育補助材13を適宜混合してなるものである。また、前記肥料袋8は、植物の生育を助長するための肥料や保水材などを適宜混合した肥料材8aを適宜の袋8b内に収容してなるものである。
【0015】さらに、前記補強部材7は、例えば、板状体(金属,プラスチック,木材等)が使用でき、好ましくは、平面視長方形の金網よりなる。この金網7は、例えば、植生ネット2の目合いよりも大きい目合いを有しており、鞘部10内に挿入できるように、10cm程度の高さHを有している。
【0016】次に、この発明の緑化方法について、図1〜図3を参照しながら説明すると、まず、緑化対象面(施工対象面)である法面1を適宜整備して、凹凸した部分をできるだけ少なくなるように整地する(必ずしも平坦な面にする必要はない)。
【0017】前記整地後の法面1に、複数の鞘部10および肥料袋収納部11が互いに平行になるように形成されている植生ネット2を、鞘部10および肥料袋収納部11が法面1の等高線に平行になるように敷設する。
【0018】次いで、前記鞘部10および肥料袋収納部11のそれぞれに金網7および肥料袋8を収容する。そして、特に、鞘部10内の金網7は、図1および図2に示すように、鉛直方向またはほぼ鉛直方向となるように法面1に立設し、その後、アンカーピン6を法面1に打ち込んで、前記金網7が法面1において所定の姿勢を保持させる。これによって、法面1には、植生ネット2の鞘部10とこれに装填される金網7とからなる複数の植生基材受け部3が適宜の間隔をおいて法面1の等高線と平行に立設される。なお、この植生基材受け部3は、前記等高線と平行な方向において必ずしも連続している必要はなく、同じ等高線位置において植生基材受け部3を適宜の間隔をおいて立設してあってもよい。
【0019】その後、図1に示すように、適宜の吹付け装置(図示していない)を用いて、植生基材4を、各植生基材受け部3の上方側の法面1に吹き付けるのである。この植生基材4の吹き付けによって、法面1には、図2に示すような断面形状が直角三角形状の複数の植生帯5が適宜の間隔をおいて法面1の等高線に平行となるように形成される。
【0020】上記法面1に形成された植生帯5は、法面1から高々10cm程度突出している低い囲いであり、この植生帯5の間の法面部分1aは、植生ネット2が敷設された人工的な裸地部分となっており、しかも、この裸地部分1aには、図2に示すように、肥料袋8が設けられているだけであるので、裸地部分1aに周辺から植物種子が入り易い。そして、この裸地部分1aの周囲の植生帯5は植生基材4を含むものであり、この植生基材4から植物が生育し、裸地部分1aを遮光し、防風する。したがって、裸地部分1aの乾燥が巧みに防止され、余所から飛来してきた種子の発芽が促進される。発芽した植物種子は保水性に優れ、かつ肥料袋8を有する裸地部分1aにおいてより確実により速く生育する。したがって、植生の遷移が促進され、自然度の高い緑化が行われる。
【0021】そして、上記緑化方法においては、緑化対象面である法面1全体に植生基材4を吹き付けるのではなく、法面1に段々状に形成される植生基材受け部3にのみ吹き付けるだけでよいので、表土の採取量が少なくて済み、周囲環境に及ぼされる悪影響がほとんど無いとともにコスト安に施工することができる。
【0022】また、上記緑化方法においては、法面1に植生ネット2を敷設するようにしているので、法面1の崩落が巧みに防止される。また、この植生ネット2の素材を腐食性素材で形成した場合、植生ネット2が経時変化により法面1に同化し、環境をより保護することができる。さらに、鞘部10に金網7を収容する場合、金網7の目合いを大きくしても、植生ネット2により植生基材4を確実に保持することができ、また、それらの網目が互いに重ならないようにすることにより、それらによって形成される目合いをより小さいものとすることができるので、植生基材受け部3によって植生基材4をより確実に保持することができる。
【0023】ところで、上記実施の形態においては、法面1に植生ネット2を敷設した後、植生ネット2に形成された鞘部10および肥料袋収納部11にそれぞれ補強部材7および肥料袋8を収容しているが、これに代えて、前記鞘部10および肥料袋収納部11に補強部材7および肥料袋8を工場などにおいて予め収容しておき、この補強部材7および肥料袋8を備えた植生ネット2を法面1に敷設するようにしてもよい。
【0024】なお、上記実施の形態において、補強部材7として金網を用いているが、これに代えて、プラスチック製の網を用いてもよい。また、多数の孔を穿設した板状体(金属製、プラスチック製、木製等)を用いてもよい。
【0025】また、法面1において土砂分が多いような場合、このような法面1に植生ネット2を敷設するに際しては、図4に示すように、植生ネット2の法面1側に木毛14を設けるようにすれば、前記法面1の浸食が効果的に防止される。
【0026】図5は、この発明の第2の実施の形態を示すもので、この実施の形態においては、鞘部10を、例えば、鉄筋など適宜の持ち上げ部材によって所定高さになるように保持している。すなわち、この図において、15は鞘部10に挿通される持ち上げ部材としての鉄筋で、この鉄筋15は、法面1に打ち込まれるアンカーピンなどの保持部材16によって水平に保持されている。この場合、保持部材16は、図5において仮想線で示すように、鉄筋15によって鞘部10が法面1から最も離間した状態で鉛直方向またはほぼ鉛直方向に張設されるように、法面1に打ち込まれる。つまり、この実施の形態における植生基材受け部3は、鉄筋のような持ち上げ部材15によって鉛直方向またはほぼ鉛直方向に立設される鞘部10によって形成されている。
【0027】このような構成を有する植生基材受け部3を法面1に形成した緑化方法においても、前記第1の実施の形態と同様の作用効果を奏することはいうまでもない。また、この実施の形態における緑化方法は、第1の実施の形態のものに比べて植生基材受け部3の構成が簡単であり、それだけ、施工コストが低減される。なお、持ち上げ部材15は、鞘部10を所定の高さ位置に水平状態に保持できるものであればよく、したがって、材質としては金属やプラスチックであってもよく、形状としては、棒状や管状であってもよい。
【0028】
【発明の効果】以上説明したように、この発明の緑化方法は、緑化対象面の周囲環境に悪影響を与えることなく、これとマッチした緑化を安価かつ確実に行うことができ、自然度の高い緑化を達成することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for greening a slope such as a slope.
[0002]
[Prior art]
[Patent Document 1] Japanese Patent Application Laid-Open No. 2002-332624 In recent years, there has been an increasing demand for using plants around a greening construction site in consideration of biodiversity and prevention of gene disruption. A method of greening this seed bank by collecting and using seeds, or collecting a topsoil seed bank containing seeds of plant growing there from the surface soil around the construction site and the forest around the construction site as buried seeds There is a growing tendency to use it and it is being implemented.
[0003]
However, in the above-mentioned revegetation method utilizing the topsoil seed bank, if the entire surface is to be replanted by spraying an inclined surface such as a slope, which is a replanting target surface, the replanting process may be difficult. The amount of topsoil to be collected increases, and the effect on the surrounding environment increases, and the cost increases. In addition, there is a problem that intrusion of the target woody tree is delayed.
The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to make it possible to perform inexpensive and reliable greening without adversely affecting the surrounding environment of the greening target surface. Another object of the present invention is to provide a method of greening an inclined surface (hereinafter, simply referred to as a greening method) that can perform greening with high naturalness.
[0005]
In order to achieve the above object, the present invention provides a method for greening, comprising laying a vegetation net having a sheath on an inclined surface to be greened, and then appropriately setting a height on the sheath. And a vegetation base receiving portion formed by the sheath portion and the reinforcing member at an appropriate height and parallel to the contour line of the inclined surface, and a topsoil seed is formed on the inclined surface on the upper side of the vegetated substrate receiving portion. A vegetation base material including a bank is sprayed (claim 1).
Further, according to the method for greening of the present invention, a vegetation net in which a reinforcing member having an appropriate height is inserted in advance in a sheath portion is laid on an inclined surface to be greened, and the vegetation net is appropriately formed by the sheath portion and the reinforcing member. A vegetation base material receiving portion having a height and parallel to the contour line of the slope is formed, and a vegetation base material including a topsoil seed bank is sprayed on the inclined surface on the upper side of the vegetation base material receiving portion ( Claim 2).
In any of the above-mentioned revegetation methods, a vegetation base receiving portion made of a sheath formed on a part of the vegetation net and a reinforcing member is provided on an inclined surface which is a revegetation target surface (or a construction target surface) at an appropriate interval. The vegetation base material including the topsoil seed bank is sprayed on the inclined surface on the upper side of the vegetation base material receiving portion, so that the vegetation base material is formed so as to be parallel to the height and the contour line as appropriate. A plurality of vegetation zones are formed so as to be parallel to the contour lines. And the slopes other than these vegetation zones are artificial bare land, plant seeds are easy to enter from the periphery, transition of vegetation is promoted, and natural greening can be performed. Then, instead of spraying the vegetation base material including the topsoil seed bank on the entire inclined surface, only spraying on the inclined surface on the upper side of the vegetation base material receiving portion formed so as to be dotted on the inclined surface. Since it is good, the amount of topsoil collected can be small, there is almost no adverse effect on the surrounding environment, and the cost can be reduced. In addition, a plurality of vegetation zones formed by spraying a vegetation base material on the inclined surface improves water retention of the bare land and promotes germination of seeds flying from other places.
[0008] When a net such as a wire net or a plastic net is used as the reinforcing member (claim 3), a lightweight reinforcing member can be obtained, and its shape is appropriately deformed according to the unevenness of the inclined surface. It is possible to make the gap of the installation part as small as possible. And as this net, a commercially available one can be used, so that the construction cost can be kept low, and since the vegetation net is provided, even if the mesh of the net is enlarged, it can be sprayed. The runoff of the vegetation base material can be skillfully prevented.
[0009] In order to achieve the above object, the present invention provides a method for greening, wherein a vegetation net is laid on an inclined surface to be greened so that a sheath portion parallel to the contour of the inclined surface is formed. The top of the sheath is lifted by a lifting member held in parallel to the contour of the inclined surface to form a vegetation base material receiving portion, and a topsoil seed bank is formed on the upper inclined surface of the vegetation base material receiving portion. A vegetation base material containing is sprayed (claim 4).
[0010] Even in this case, the same effect as the greening method according to claim 1 or 2 can be obtained, and the vegetation net itself constitutes the vegetation base material receiving portion. The configuration of the receiving portion is simple, and the construction cost is lower.
If a fertilizer bag is attached to the vegetation net (claim 5), the transition of the plant is further promoted.
[0012]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment of the present invention. First, in FIGS. 1 and 2, reference numeral 1 denotes an inclined surface as a greening target surface, for example, a slope. Reference numeral 2 denotes a vegetation net laid on the upper surface of the slope 1, and a plurality of vegetation base material receiving portions 3 are formed on the vegetation net 2 at appropriate intervals in parallel with the contour lines of the slope 1. The vegetation base material 4 is sprayed on the slope 1 above the vegetation base material receiving portions 3 to form a plurality of vegetation zones 5. Reference numeral 6 denotes an anchor pin for holding a reinforcing member 7 (described later) that forms the vegetation base material receiving portion 3 as a part of the vegetation net 2 in a predetermined posture, 8 denotes a fertilizer bag attached to the vegetation net 2, 9 Is a spray nozzle of a vegetation substrate spraying machine (not shown).
The vegetation net 2 is braided in a rectangular shape in a plan view as shown in FIG. On the surface of the vegetation net 2, a plurality of sheaths 10 having a height of, for example, about 10 cm for accommodating the reinforcing member 7 and a fertilizer bag 8 when the longitudinal direction is Y and the transverse direction is X. The fertilizer bag storage section 11 to be stored is formed in the X direction at an appropriate interval.
The vegetation base material 4 includes a topsoil seed bank. More specifically, the vegetation base material 4 includes topsoil (plant seeds 12) such as a mountain or a forest near the slope 1. ) Is appropriately mixed with a growth aid 13 such as peat moss, bark compost, and water retention material. The fertilizer bag 8 is a fertilizer material 8a obtained by appropriately mixing a fertilizer, a water retention material, and the like for promoting the growth of plants, and is accommodated in an appropriate bag 8b.
Further, the reinforcing member 7 can be, for example, a plate-like body (metal, plastic, wood, or the like), and is preferably made of a wire net having a rectangular shape in a plan view. The wire mesh 7 has, for example, a mesh size larger than that of the vegetation net 2, and has a height H of about 10 cm so that it can be inserted into the sheath portion 10.
Next, the greening method of the present invention will be described with reference to FIGS. 1 to 3. First, a slope 1 which is a greening target surface (construction target surface) is appropriately maintained, and irregular portions are removed. Level the ground as little as possible (not necessarily a flat surface).
On the slope 1 after the leveling, the vegetation net 2 in which a plurality of pods 10 and a fertilizer bag storage section 11 are formed in parallel to each other is used. It is laid so as to be parallel to the contour line of the surface 1.
Next, the wire net 7 and the fertilizer bag 8 are stored in the sheath 10 and the fertilizer bag storage 11, respectively. In particular, as shown in FIGS. 1 and 2, the wire mesh 7 in the sheath portion 10 is erected on the slope 1 so as to be in a vertical direction or substantially in a vertical direction. To hold the wire mesh 7 in a predetermined posture on the slope 1. Thereby, on the slope 1, a plurality of vegetation base material receiving portions 3 including the sheath portion 10 of the vegetation net 2 and the wire mesh 7 loaded therein are arranged at appropriate intervals in parallel with the contour lines of the slope 1. It is erected. Note that the vegetation base material receiving portion 3 does not necessarily need to be continuous in a direction parallel to the contour line, and the vegetation base material receiving portion 3 is erected at an appropriate interval at the same contour position. Is also good.
Thereafter, as shown in FIG. 1, the vegetation base material 4 is sprayed on the slope 1 above the vegetation base material receiving portions 3 using an appropriate spraying device (not shown). is there. By spraying the vegetation base material 4, a plurality of vegetation zones 5 having a right-angled triangular cross section as shown in FIG. 2 are parallel to the contour line of the slope 1 at appropriate intervals on the slope 1. Formed.
The vegetation zone 5 formed on the slope 1 is a low enclosure projecting at most about 10 cm from the slope 1, and a vegetation net 2 is laid between the vegetation zones 5 on the slope portion 1a. As shown in FIG. 2, only the fertilizer bag 8 is provided in the bare land portion 1a. Seeds are easy to enter. The vegetation zone 5 around the bare land portion 1a includes the vegetation base material 4. Plants grow from the vegetation base material 4, and the bare land portion 1a is shielded from light and windproof. Accordingly, drying of the bare land portion 1a is skillfully prevented, and germination of seeds flying from other places is promoted. The germinated plant seeds are excellent in water retention and grow more reliably and faster in the bare part 1 a having the fertilizer bag 8. Therefore, vegetation transition is promoted, and greening with a high degree of naturalness is performed.
In the above-described greening method, the vegetation base material 4 is sprayed not on the entire slope 1 to be greened, but only on the vegetation base receiving portion 3 formed stepwise on the slope 1. Therefore, the amount of topsoil collected is small, there is almost no adverse effect on the surrounding environment, and the cost can be reduced.
Further, in the above-mentioned greening method, since the vegetation net 2 is laid on the slope 1, the collapse of the slope 1 is skillfully prevented. When the material of the vegetation net 2 is formed of a corrosive material, the vegetation net 2 can be assimilated to the slope 1 due to a change with time, and the environment can be further protected. Furthermore, when the wire mesh 7 is accommodated in the sheath portion 10, even if the mesh of the wire mesh 7 is increased, the vegetation base material 4 can be securely held by the vegetation net 2, and the meshes do not overlap each other. By doing so, the mesh formed by them can be made smaller, so that the vegetation base material 4 can be more reliably held by the vegetation base material receiving portion 3.
In the above embodiment, after the vegetation net 2 is laid on the slope 1, the reinforcing member 7 and the fertilizer bag 8 are respectively placed on the sheath 10 and the fertilizer bag storage 11 formed on the vegetation net 2. Instead, the reinforcing member 7 and the fertilizer bag 8 were previously stored in the sheath portion 10 and the fertilizer bag storage portion 11 in a factory or the like, and the reinforcing member 7 and the fertilizer bag 8 were provided. The vegetation net 2 may be laid on the slope 1.
In the above embodiment, a wire mesh is used as the reinforcing member 7, but a plastic net may be used instead. Further, a plate-like body (metal, plastic, wooden, etc.) having a large number of holes may be used.
When the slope 1 has a lot of sediment, when the vegetation net 2 is laid on the slope 1, as shown in FIG. If the hairs 14 are provided, erosion of the slope 1 is effectively prevented.
FIG. 5 shows a second embodiment of the present invention. In this embodiment, the sheath 10 is held at a predetermined height by an appropriate lifting member such as a reinforcing bar. are doing. That is, in this figure, reference numeral 15 denotes a reinforcing bar as a lifting member inserted into the sheath 10, and the reinforcing bar 15 is horizontally held by a holding member 16 such as an anchor pin driven into the slope 1. In this case, as shown by the imaginary line in FIG. 5, the holding member 16 is sloped on the slope so that the sheath 10 is stretched in the vertical direction or almost vertically by the reinforcing bar 15 with the sheath 10 being most distant from the slope 1. Driving into 1. In other words, the vegetation base material receiving portion 3 in this embodiment is formed by the sheath portion 10 that is erected in the vertical direction or almost vertically by the lifting member 15 such as a reinforcing bar.
It is needless to say that the greening method in which the vegetation base material receiving portion 3 having such a configuration is formed on the slope 1 has the same operation and effect as the first embodiment. Further, in the greening method according to this embodiment, the configuration of the vegetation base material receiving portion 3 is simpler than that of the first embodiment, and accordingly, the construction cost is reduced. The lifting member 15 may be any member that can hold the sheath portion 10 at a predetermined height in a horizontal state. Therefore, the material may be metal or plastic, and the shape may be a rod or a tube. There may be.
[0028]
As described above, the greening method according to the present invention can perform greening inexpensively and surely without adversely affecting the surrounding environment of the greening target surface, and has high naturalness. Greening can be achieved.
