Description

本発明は、山間地等の傾斜面や新規造成地の傾斜面などに植物が生育可能な法面を構築するための法面緑化用支持部材および法面緑化工法に関する。   The present invention relates to a support member for slope revegetation and a slope replanting method for constructing a slope where plants can grow on slopes such as mountainous areas and slopes of newly constructed land.

山間地あるいは新規造成地などの傾斜地盤においては、景観の向上などを目的として、法面の緑化工事が施工されている。このような法面緑化工事では、従来、地盤面に土砂崩壊防止用の補助部材やネットなどを固定して、これらの上に客土層を形成する工法が採用されている。また、このような法面緑化工事で使用する補助部材やネットなどについても様々なものが開発されている。   On sloped ground such as mountainous areas or newly developed land, slope planting work is being carried out for the purpose of improving the landscape. In such slope revegetation work, conventionally, a construction method is adopted in which an auxiliary member for preventing sediment collapse or a net is fixed to the ground surface, and a guest soil layer is formed thereon. In addition, various auxiliary members and nets have been developed for use in such slope planting work.

従来の法面緑化技術としては、例えば特許文献1,2などで開示されているものがある。特許文献1に開示されている法面緑化工法においては、施工面に固定した土留め用ストッパ上に、苗木根が貫通可能な植生袋に混合土壌を充填したものを設置、固定し、この植生袋に苗木を植えることによって緑化法面を構築する。また、特許文献2に開示されている法面緑化工法においては、法面上に多数の柵状体を連結固定して複数の堰を形成し、これらの堰の上方を網状体で覆い、さらに、その上に肥料や植物種子などを含む客土などを施して着根層を形成することによって緑化法面を構築する。   Examples of conventional slope greening techniques are disclosed in Patent Documents 1 and 2, for example. In the slope revegetation method disclosed in Patent Document 1, a vegetation bag filled with mixed soil in a vegetation bag through which seedling roots can penetrate is fixed on a soil retaining stopper fixed on the construction surface. A greening slope is constructed by planting saplings in the bag. Further, in the slope revegetation method disclosed in Patent Document 2, a plurality of fences are connected and fixed on the slope to form a plurality of weirs, and the upper part of these weirs is covered with a mesh body, A greening slope is constructed by forming a root layer by applying soil including fertilizer and plant seeds on it.

また、その他の法面緑化工法として、本発明者が提案した特許文献3に開示の法面緑化工法がある。この法面緑化工法では、木材を素材とする支持部材を地盤上に棚状または千鳥状に配置し、地盤と支持部材との間に、連続気泡を有する発泡ガラスの塊状体を布設し、支持部材および塊状体を覆う客土層を形成する。この法面緑化工法によれば、木材を素材とする支持部材が適度の吸水性および保水性を備えており、発泡ガラスの塊状体が多数の連続気泡を有していることで、地下水や雨水などを適度に吸収し、過剰な水分を透過する機能を備えているため、支持部材を地盤上に棚状または千鳥状に配置し、地盤と支持部材との間に塊状体を布設し、これらを覆う客土層を形成すれば、客土層の流出や崩落が防止されるとともに優れた保水性を発揮し、植物の成長に必要な水分や水分中に含まれる養分などを長期間保持することができ、植物の生育が良好な緑化法面を構築することができる。   Further, as another slope greening method, there is a slope greening method disclosed in Patent Document 3 proposed by the present inventor. In this slope revegetation method, support members made of wood are arranged in a shelf or staggered pattern on the ground, and a foamed glass lump having open cells is laid between the ground and the support member for support. A soil layer covering the member and the lump is formed. According to this slope greening method, the support member made of wood has appropriate water absorption and water retention, and the lump of foamed glass has a large number of open cells. The support members are arranged in a shelf or staggered pattern on the ground, and a lump is laid between the ground and the support members. If the soil layer that covers the soil is formed, the soil layer will be prevented from flowing out and collapsing, exhibiting excellent water retention, and maintain the moisture and nutrients contained in the moisture for a long period of time. Therefore, it is possible to construct a planting method with good plant growth.

特許文献1に開示されている法面緑化工法の場合、施工面に固定した土留め用ストッパ上に、混合土壌を充填した植生袋をそれぞれ設置、固定しなければならないので、混合土壌の充填作業、混合土壌が充填された植生袋の運搬作業および設置作業などに多大な労力と時間とを要し、工期が長期化する。   In the case of the slope revegetation method disclosed in Patent Document 1, vegetation bags filled with mixed soil must be installed and fixed on the soil retaining stoppers fixed to the construction surface, so the mixed soil filling operation In addition, a lot of labor and time are required for carrying and installing the vegetation bag filled with the mixed soil, and the construction period is prolonged.

また、特許文献2に開示された法面緑化工法は、多数の柵状体を連結固定して堰を形成するものであるため、各々の柵状体にはそれぞれ連結機構を設ける必要があり、その構造が複雑で製作に多くの手間を要している。また、柵状体を横方向に連結固定して連続した堰を形成する必要があるので、凹凸や起伏の多い法面においては採用が困難である。   In addition, since the slope revegetation method disclosed in Patent Document 2 is to form a weir by connecting and fixing a large number of fence-like bodies, it is necessary to provide a connection mechanism for each fence-like body, The structure is complex and requires a lot of work to produce. In addition, since it is necessary to form a continuous weir by connecting and fixing the fence-like bodies in the lateral direction, it is difficult to adopt it on slopes with many irregularities and undulations.

特許文献3に開示された法面緑化工法は、これらの法面緑化工法の問題点を解決するものであるが、この工法では、木材を素材とする支持部材を地盤上に配置した後に、地盤と支持部材との間に連続気泡を有する発泡ガラスの塊状体を布設する必要がある。   The slope revegetation method disclosed in Patent Document 3 solves the problems of these slope revegetation methods, but in this method, after placing a support member made of wood on the ground, It is necessary to lay a lump of foamed glass having open cells between the support member and the support member.

そこで、本発明においては、特許文献3に開示された従来の法面緑化工法をさらに改良し、材料点数および施工工数を少なくすることが可能な法面緑化用支持部材および法面緑化工法を提供することを目的とする。   Therefore, in the present invention, the conventional slope greening method disclosed in Patent Document 3 is further improved to provide a slope greening support member and a slope greening method capable of reducing the number of materials and construction man-hours. The purpose is to do.

本発明の法面緑化用支持部材は、地盤上に棚状または千鳥状に配置される法面緑化用支持部材であって、連続気泡を有する発泡ガラスと、この発泡ガラスが充填される筒状籠とから構成されるものである。そして、本発明の法面緑化工法は、この法面緑化用支持部材を地盤上に棚状または千鳥状に配置し、法面緑化用支持部材を覆うように客土層を形成することを特徴とする。   The slope greening support member of the present invention is a slope greening support member arranged in a shelf or staggered pattern on the ground, and has a foamed glass having open cells and a cylindrical shape filled with the foamed glass. It is composed of firewood. The slope greening method of the present invention is characterized in that the slope greening support members are arranged in a shelf or zigzag pattern on the ground, and a soil layer is formed so as to cover the slope greening support members. And

本発明の法面緑化用支持部材では、筒状籠内に充填された連続気泡を有する発泡ガラスが、地下水や雨水などを適度に吸収し、過剰な水分を透過する機能を備えるとともに、この発泡ガラスが充填された筒状籠が、従来の木材を素材とする支持部材と同等の客土層の支持機能を発揮する。そのため、この法面緑化用支持部材を地盤上に棚状または千鳥状に配置し、この法面緑化用支持部材を覆うように客土層を形成すれば、客土層の流出や崩落が防止される。また、この客土層は優れた保水性と保肥機能を発揮し、植物の生長に必要な水分や水分中に含まれる養分などを長期間保持することができ、植物の生育が良好な緑化法面を構築することができる。   In the slope greening support member of the present invention, the foamed glass having open cells filled in the cylindrical cage has a function of absorbing groundwater and rainwater appropriately and transmitting excess water, and this foaming. The cylindrical basket filled with glass demonstrates the support function of the guest soil layer equivalent to a support member made of conventional wood. Therefore, if this slope greening support member is placed on the ground in a shelf or zigzag form, and the customer soil layer is formed so as to cover this slope greening support member, the outflow and collapse of the customer soil layer is prevented. Is done. In addition, this soil layer exhibits excellent water retention and fertilization functions, can maintain the moisture necessary for plant growth and nutrients contained in the moisture for a long time, and planting with good planting A slope can be constructed.

また、ここで生育する植物の根は筒状籠に絡むように伸長するので、客土層の流出、崩落や植物の脱落などが防止される。また、本発明の法面緑化用支持部材は筒状籠内に連続気泡を有する発泡ガラスが充填されたものであるため適度な隙間を有しており、客土層に浸透した雨水などがこの隙間を通して下方へ流出するとともに、客土層中の通気性も確保されるので、客土層の過剰水分を効率良く排出し、植物生育に適した水分量および通気性を維持できるほか、雨天などによる客土層の流出を防ぐことができる。   In addition, since the roots of the plants that grow here extend so as to be entangled with the cylindrical cocoons, it is possible to prevent the outflow, collapse, and dropout of the plants. In addition, since the sloped green support member of the present invention is filled with foamed glass having open cells in a cylindrical basket, it has an appropriate gap, and rainwater or the like that has permeated the soil layer of the soil. As it flows downward through the gap and the air permeability in the soil layer is secured, excess water in the soil layer can be efficiently discharged, maintaining the moisture content and air permeability suitable for plant growth, and rain Can prevent the outflow of the customer soil layer.

また、筒状籠内の発泡ガラスは、その外周から内部に連続した気泡を有しているため、客土層中において有益な土壌微生物などの住処となり、これらの働きによっても植物の生育が活性化される。さらに、筒状籠内の発泡ガラスはガラス質であるため化学的に安定であり、有害物質の溶出や腐食なども生じないため、環境汚染の恐れがなく、耐久性にも優れている。   In addition, the foamed glass in the cylindrical cage has bubbles that are continuous from the outer periphery to the inside, so that it becomes a place for beneficial soil microorganisms in the soil layer, and the growth of plants is also activated by these functions. It becomes. Furthermore, since the foamed glass in the cylindrical basket is glassy, it is chemically stable, and no elution or corrosion of harmful substances occurs. Therefore, there is no fear of environmental pollution and excellent durability.

ここで、筒状籠は、木や竹などにより形成された網を利用して製作することが可能であるが、合成樹脂製や金属製の網を利用して製作したものであることが望ましい。木や竹の場合には長期間経過すると腐食してしまう可能性があるが、合成樹脂の場合には腐食することがない。また、金属製の網の場合には合成樹脂よりも強度的に優れており、客土層および構築された緑化法面の重量物を支持するのに適している。特に、金属製の網では亜鉛めっきされた針金を用いるよりも、例えば銅をアルミニウム被覆した素線や亜鉛アルミニウム合金めっき鉄線を用いることが望ましい。銅をアルミニウム被覆した素線、亜鉛アルミニウム合金めっき鉄線や合成樹脂は耐腐食性に優れており、長期間に渡り、客土層および構築された緑化法面を支持することができる。また、筒状籠は、円筒状、三角筒状や四角筒状など様々な断面形状のものを用いることが可能である。   Here, the cylindrical basket can be manufactured using a net formed of wood or bamboo, but is preferably manufactured using a synthetic resin or metal net. . In the case of wood and bamboo, there is a possibility of corrosion after a long period of time, but in the case of synthetic resin, there is no corrosion. Further, in the case of a metal net, it is superior in strength to a synthetic resin, and is suitable for supporting a heavy soil layer and a constructed greening slope. In particular, for a metal net, it is desirable to use, for example, an element wire coated with aluminum with aluminum or a zinc aluminum alloy-plated iron wire, rather than using a galvanized wire. Copper-aluminum-coated strands, zinc-aluminum alloy-plated iron wires, and synthetic resins are excellent in corrosion resistance, and can support the soil layer and the constructed greening slope for a long period of time. In addition, as the cylindrical rod, those having various cross-sectional shapes such as a cylindrical shape, a triangular cylindrical shape, and a rectangular cylindrical shape can be used.

また、本発明の法面緑化工法は、連続気泡を有する発泡ガラスと、この発泡ガラスが充填される筒状籠とから構成される法面緑化用支持部材を、地盤上に棚状または千鳥状に配置し、地盤および法面緑化用支持部材を覆う状態に網状体を張設し、さらに、法面緑化用支持部材を覆うように客土層を形成することを特徴とする。   Further, the slope revegetation method of the present invention includes a sloped or staggered support member for slope greening composed of foam glass having open cells and a cylindrical basket filled with the foam glass. The mesh body is stretched in a state of covering the ground and the slope greening support member, and the soil layer is formed so as to cover the slope greening support member.

地盤上に配置された法面緑化用支持部材を覆うように網状体を張設し、この上に客土層を形成するので、客土層はより強固に固定され、ここで生育する植物の根は網状体に絡むように伸長するので、客土層の流出、崩落や植物の脱落などを防止する機能がさらに向上する。   A net-like body is stretched so as to cover the support member for slope planting arranged on the ground, and the soil layer is formed on this, so the soil layer is more firmly fixed and the plant growing here Since the roots are stretched so as to be entangled with the nets, the function of preventing the outflow, collapse and dropping of the plant of the soil layer is further improved.

ここで、客土層を、連続気泡を有する発泡ガラスで形成された粒状体と堆肥と植物種子と粘着材とを含有する基盤材を地盤上に吹き付けて硬化させることにより形成することができる。このような基盤材を吹き付けて硬化させることにより、客土層の表面は植物が生長可能な適度の硬さとなり、工事完了後も長期間に渡りその硬さが保たれるだけでなく、客土層内においては、基盤材に含有される粘着材の作用により、発泡ガラスの粒状体、堆肥、植物種子などが互いに固結して団粒化構造が形成されるため、降雨などによる客土層の浸食、風による基盤材の飛散などが発生せず、耐久性に優れた緑化法面を構築することができる。また、この客土層は乾燥時期においても適度の保水性を維持することができるため、植物が枯死するようなことがなく、安定した生育状態を確保することができる。   Here, the customer soil layer can be formed by spraying a base material containing granular materials, compost, plant seeds, and an adhesive material formed of foamed glass having open cells on the ground and curing. By spraying and curing such a base material, the surface of the customer soil layer has an appropriate hardness that allows the plant to grow. In the soil layer, the granular material of foamed glass, compost, and plant seeds are consolidated together by the action of the adhesive material contained in the base material to form an aggregated structure. No erosion of the layer or scattering of the base material due to the wind occurs, and a greening slope with excellent durability can be constructed. Moreover, since this soil layer can maintain a suitable water retention even during the dry season, the plant does not die, and a stable growth state can be ensured.

また、客土層を構成する基盤材が発泡ガラスの粒状体を含有していることにより、客土層の内部に、植物の根や芽などの生育に必要とされる隙間を確保することができるので、工事完了後、発芽した植物種子は堆肥などに含まれる養分を吸収しながら客土層の表面から外部へ成長していき、緑豊かな緑化法面を構築することができる。この粒状体は、多数の微小連続気泡を有する発泡ガラスで形成され、比較的軽量で、地下水や雨水などを適度に吸収し、余分な水分は透過する機能を備えているため、工事完了後、長期間経過しても、初期の軽量性が失われることがなく、客土層の流出や崩落などを防止することができる。   In addition, since the base material constituting the soil layer contains the foamed glass granules, it is possible to secure gaps necessary for the growth of plant roots and buds in the soil layer. Therefore, after the construction is completed, the germinated plant seeds can grow from the surface of the soil layer to the outside while absorbing nutrients contained in the compost, etc., and a rich greening slope can be constructed. This granular material is formed of foamed glass with a large number of minute open cells, is relatively light, absorbs groundwater and rainwater appropriately, and has the function of allowing excess moisture to pass through. Even after a long period of time, the initial lightweight property is not lost, and the outflow or collapse of the soil layer can be prevented.

さらに、この客土層に含まれる発泡ガラスについても、前述のように、その外周から内部へ連続した気泡を有するため、客土層中において有益な土壌微生物などの住処となり、これらの働きによっても植物の生育状態が活性化される。これらの粒状体はガラス質であるため化学的に安定であり、有害物質の溶出や腐食なども生じないため、環境汚染のおそれがなく、耐久性にも優れている。なお、発泡ガラスの粒状体は、新たなガラス材はもちろん、廃棄された空瓶やガラス廃材などを原料として製造することもできるため、資源の有効活用を図り、資源環境の保護に寄与することができる。   Furthermore, as described above, the foam glass contained in this soil layer also has a continuous bubble from the outer periphery to the inside, so that it becomes a place of residence for beneficial soil microorganisms in the soil layer, and also due to these functions. The growth state of the plant is activated. Since these granular materials are glassy, they are chemically stable, and no leaching of harmful substances or corrosion occurs, so there is no risk of environmental pollution and excellent durability. In addition, since the granular material of foamed glass can be produced using not only new glass materials but also discarded empty bottles and glass waste materials as raw materials, it is intended to effectively utilize resources and contribute to the protection of the resource environment. Can do.

なお、堆肥としては、落ち葉、藁、塵芥、野草などを積み重ね、腐敗させて作った有機物質の混合物が好適であり、客土層に含有される植物種子が成長する際の養分供給源となるほか、保肥力の増強、保水性や通気性の改善、土壌微生物の活動促進などの作用があるため、良好な植物生育基盤を形成することができる。この場合、基盤材に各種化学肥料を添加しておけば、植物の成長をさらに促進することができる。   As compost, a mixture of organic substances made by stacking fallen leaves, straw, dust, wild grass, etc. and decaying is suitable, and it becomes a nutrient source when plant seeds contained in the soil layer grow In addition, since it has effects such as enhancement of fertilizer retention, improvement of water retention and air permeability, and promotion of soil microorganism activity, a good plant growth base can be formed. In this case, if various chemical fertilizers are added to the base material, the growth of the plant can be further promoted.

また、法面緑化用支持部材は、外径が円筒状籠の編み目の内径よりも大きな頭部を有するアンカーにより固定することが望ましい。これにより、このアンカーを打ち込むと、その頭部が円筒状籠の編み目に掛かるようになり、アンカーを打ち込むだけで簡単に法面緑化用支持部材を地盤の表面に固定することが可能となる。   Further, the slope greening support member is preferably fixed by an anchor having an outer diameter that is larger than the inner diameter of the stitch of the cylindrical rod. As a result, when the anchor is driven, the head of the anchor comes into contact with the stitch of the cylindrical hook, and the slope greening support member can be easily fixed to the surface of the ground simply by driving the anchor.

あるいは、法面緑化用支持部材は、この法面緑化用支持部材の外周に掛かる略U字状または略J字状のフック部を有するアンカーにより固定することが望ましい。これにより、これらのアンカーを打ち込むと、法面緑化用支持部材の外周が略U字状のフック部または略J字状のフック部の内側に掛かるようになり、アンカーを打ち込むだけで簡単に法面緑化用支持部材を地盤の表面に固定することが可能となる。   Alternatively, the slope greening support member is preferably fixed by an anchor having a substantially U-shaped or substantially J-shaped hook portion that hangs on the outer periphery of the slope greening support member. As a result, when these anchors are driven, the outer periphery of the slope greening support member comes to hang on the inside of the substantially U-shaped hook portion or the substantially J-shaped hook portion. It becomes possible to fix the support member for greening to the surface of the ground.

(1)連続気泡を有する発泡ガラスと、この発泡ガラスが充填される筒状籠とから構成される法面緑化用支持部材を、地盤上に棚状または千鳥状に配置し、法面緑化用支持部材を覆うように客土層を形成することにより、客土層の流出や崩落が発生せず、保水性に優れ、植物の生育も良好な緑化法面を構築できる。特に、本発明では、発泡ガラスが充填された筒状籠を地盤上に配置するだけで、客土層を形成することが可能であるため、従来のように木材を素材とする支持部材を地盤上に配置した後に、地盤と支持部材との間に発泡ガラスの塊状体を敷設する必要がなく、材料点数および施工工数が少なくなる。また、ここで生育する植物の根は筒状籠に絡むように伸長するので、客土層の流出、崩落や植物の脱落などが防止される。さらに、本発明の法面緑化用支持部材が筒状籠内に連続気泡を有する発泡ガラスが充填されたものであるため適度な隙間を有しており、客土層に浸透した雨水などがこの隙間を通して下方へ流出するとともに、客土層中の通気性も確保されるので、客土層の過剰水分を効率良く排出し、植物生育に適した水分量および通気性を維持できるほか、雨天などによる客土層の流出を防ぐことができる。 (1) A slope greening support member composed of foamed glass having open cells and a cylindrical basket filled with the foamed glass is arranged in a shelf or staggered pattern on the ground, for slope greening By forming the soil layer so as to cover the support member, it is possible to construct a revegetation slope with excellent water retention and good plant growth, without causing outflow or collapse of the soil layer. In particular, in the present invention, it is possible to form a guest soil layer simply by placing a cylindrical basket filled with foamed glass on the ground. It is not necessary to lay a lump of foamed glass between the ground and the support member after the arrangement, and the number of materials and construction man-hours are reduced. In addition, since the roots of the plants that grow here extend so as to be entangled with the cylindrical cocoons, it is possible to prevent the outflow, collapse, and dropout of the plants. Furthermore, since the support member for slope planting of the present invention is filled with foamed glass having open cells in a cylindrical basket, it has an appropriate gap, and rainwater or the like that has permeated into the soil layer has As it flows downward through the gap and the air permeability in the soil layer is secured, excess water in the soil layer can be efficiently discharged, maintaining the moisture content and air permeability suitable for plant growth, and rain Can prevent the outflow of the customer soil layer.

(2)連続気泡を有する発泡ガラスと、この発泡ガラスが充填される筒状籠とから構成される法面緑化用支持部材を、地盤上に棚状または千鳥状に配置し、地盤および法面緑化用支持部材を覆う状態に網状体を張設し、さらに、法面緑化用支持部材を覆うように客土層を形成することにより、保水性に優れ、植物の流出、崩落や植物の脱落などを防止する機能がさらに向上する。 (2) A slope greening support member composed of foamed glass having open cells and a cylindrical basket filled with the foamed glass is arranged in a shelf or staggered manner on the ground, and the ground and slope A net is stretched over the support member for greening, and a soil layer is formed so as to cover the support member for slope greening. The function to prevent such is further improved.

(3)客土層を、連続気泡を有する発泡ガラスの粒状体と堆肥と植物種子と粘着材とを含有する基盤材を地盤上に吹き付けて硬化させることによって形成すると、降雨などによる客土層の浸食、風による基盤材の飛散などが発生せず、保水性および耐久性に優れた緑化法面を構築することができ、植物の生育状態もさらに安定する。 (3) When the base soil layer is formed by spraying a base material containing foamed glass granules having open cells, compost, plant seeds, and an adhesive on the ground, the base soil layer due to rain or the like No erosion, scattering of the base material due to wind, and the like, a greening slope with excellent water retention and durability can be constructed, and the growth state of the plant is further stabilized.

(4)法面緑化用支持部材を、外径が円筒状籠の編み目の内径よりも大きな頭部を有するアンカーにより固定することにより、このアンカーを打ち込むだけで簡単に法面緑化用支持部材を地盤の表面に固定することが可能となる。 (4) By fixing the support member for slope greening with an anchor having an outer diameter larger than the inner diameter of the stitch of the cylindrical ridge, the support member for slope greening can be easily achieved simply by driving the anchor. It becomes possible to fix to the surface of the ground.

(5)法面緑化用支持部材を、この法面緑化用支持部材の外周に掛かる略U字状または略J字状のフック部を有するアンカーにより固定することにより、これらのアンカーを打ち込むだけで簡単に法面緑化用支持部材を地盤の表面に固定することが可能となる。 (5) By fixing the support member for slope greening with an anchor having a substantially U-shaped or substantially J-shaped hook portion that hangs on the outer periphery of the support member for slope greening, just driving these anchors It becomes possible to easily fix the slope greening support member to the surface of the ground.

A lid 12 formed of the same net is provided at both ends of the cylindrical basket 10 so as to be openable and closable. It is also possible to form the cylindrical cage 10 with a synthetic resin net.

なお、本実施形態において使用した円筒状籠10は、直径約50〜200mm、長さ約1〜2mのものである。また、この円筒状籠10の中央には、発泡ガラスの塊状体11を充填しても直径が一様な円筒状を維持できるように補強用の輪13が設けられている。この支持部材1では、円筒状籠10内に粒径10mm〜50mmの発泡ガラス11が充填され、蓋12が閉じられる。蓋12は、例えば針金により円筒状籠10に固定される。   The cylindrical basket 10 used in the present embodiment has a diameter of about 50 to 200 mm and a length of about 1 to 2 m. Further, a reinforcing ring 13 is provided at the center of the cylindrical bowl 10 so that a cylindrical shape having a uniform diameter can be maintained even when the foamed glass lump 11 is filled. In this support member 1, a foamed glass 11 having a particle size of 10 mm to 50 mm is filled in a cylindrical basket 10, and the lid 12 is closed. The lid 12 is fixed to the cylindrical basket 10 with a wire, for example.

本実施形態の法面緑化工法においては、まず、図2(a)および図3に示すように、軟岩、硬岩(岩盤)やモルタル吹き付けの法面などの緑化法面を構築すべき傾斜した地盤2に、図1に示す支持部材1を所定間隔ごとに配置し、アンカー3を打ち込んで固定する。このとき、支持部材1の側面の一部を地盤2の表面に密着させて固定する。なお、アンカー3は、その頭部3aの外径が円筒状籠10の編み目の内径よりも大きなものを使用する。これにより、アンカー3を打ち込むと、その頭部3aが円筒状籠10の編み目に掛かるようになるので、アンカー3を打ち込むだけで簡単に支持部材1を地盤2の表面に固定することができる。また、本実施形態では、図3に示すように、複数の支持部材1を地盤2の表面に水平かつ千鳥状に配置しているが、地盤2の強度や他の施工条件に応じて、縦横方向に0.5〜3.0m程度の間隔で配置する。   In the slope revegetation method of this embodiment, first, as shown in FIG. 2A and FIG. 3, the slope where a greening slope such as soft rock, hard rock (bedrock), or a mortar spray slope should be constructed is inclined. Support members 1 shown in FIG. 1 are arranged at predetermined intervals on the ground 2 and anchors 3 are driven and fixed. At this time, a part of the side surface of the supporting member 1 is brought into close contact with the surface of the ground 2 and fixed. In addition, the anchor 3 is used in which the outer diameter of the head 3a is larger than the inner diameter of the stitch of the cylindrical collar 10. As a result, when the anchor 3 is driven, the head 3 a comes to hang onto the stitch of the cylindrical rod 10, so that the support member 1 can be fixed to the surface of the ground 2 simply by driving the anchor 3. In the present embodiment, as shown in FIG. 3, a plurality of support members 1 are arranged horizontally and in a staggered manner on the surface of the ground 2, but depending on the strength of the ground 2 and other construction conditions, It arranges at intervals of about 0.5-3.0 m in the direction.

そして、支持部材1の配置および固定が完了したら、図2(b)に示すように、地盤2および支持部材1を覆うようにラス金網4を張設し、係止ピン5を用いて地盤2に固定する。ここで、ラス金網4とは亜鉛めっき鉄線を素材とする菱形金網のことであり、一定のピッチで山形に曲げられた列線を互いに絡ませることによって形成した平行四辺形の編み目を有する網状体である。   When the placement and fixing of the support member 1 is completed, a lath wire mesh 4 is stretched so as to cover the ground 2 and the support member 1 as shown in FIG. Secure to. Here, the lath wire mesh 4 is a rhombus wire mesh made of a galvanized iron wire, and a mesh body having parallelogram stitches formed by entanglement of row lines bent into a mountain shape at a constant pitch. It is.

ラス金網4の張設が完了したら、図2(c)に示すように、地盤2、支持部材1およびラス金網4を覆うように、地盤2に向けて基盤材6を吹き付けて硬化させることにより客土層7を形成する。基盤材6は、連続気泡を有する直径20mm以下の発泡ガラスの粒状体8、堆肥、植物種子、粘着材および化学肥料などを含有しているため、工事完了後時間が経過すると、図4に示すように、客土層7中の植物種子が発芽し外部に向かって植物20が成長していき、緑豊かな緑化法面21が構築される。   When the stretch of the lath wire mesh 4 is completed, as shown in FIG. 2 (c), the base material 6 is sprayed and cured toward the ground 2 so as to cover the ground 2, the support member 1, and the lath wire mesh 4. The customer soil layer 7 is formed. The base material 6 contains foamed glass granules 8 having a diameter of 20 mm or less having open cells, compost, plant seeds, an adhesive material, and a chemical fertilizer. Therefore, when time passes after the completion of the construction, it is shown in FIG. As described above, the plant seeds in the soil layer 7 germinate and the plant 20 grows outward, so that a green planting slope 21 is constructed.

本実施形態における支持部材1では、筒状籠10内に多数の連続気泡を有する発泡ガラスの塊状体11が充填されたものであるため、この筒状籠10内の発泡ガラスの塊状体11が地下水や雨水などを適度に吸収し、過剰な水分を透過する。したがって、この支持部材1を地盤2上に千鳥状に配置し、これらを覆う客土層7を形成すれば、客土層7は地盤2上に配置された支持部材1で強固に固定されるため、客土層7の流出や崩落が防止される。また、この客土層7は優れた保水性と保肥機能を発揮し、植物20の成長に必要な水分や水分中に含まれる養分などを長期間保持することができ、植物20が良好に生育する緑化法面21を構築することができる。   In the support member 1 in the present embodiment, the foamed glass lump 11 having a large number of open cells is filled in the cylindrical gutter 10, and therefore the foamed glass lump 11 in the cylindrical gutter 10 is Appropriately absorbs groundwater and rainwater, and permeates excess water. Therefore, if this support member 1 is arranged on the ground 2 in a zigzag pattern and the customer soil layer 7 covering them is formed, the customer soil layer 7 is firmly fixed by the support member 1 placed on the ground 2. Therefore, the outflow and collapse of the customer soil layer 7 are prevented. In addition, the soil layer 7 exhibits excellent water retention and fertilization functions, can retain moisture necessary for the growth of the plant 20 and nutrients contained in the moisture for a long period of time, and the plant 20 is excellent. A growing slope 21 can be constructed.

また、本実施形態における支持部材1は、筒状籠10内に連続気泡を有する発泡ガラス11が充填されたものであるため適度な隙間を有しており、客土層7に浸透した雨水などをこの隙間を通して下方へ流出させることができる。また、これにより、客土層7中の通気性も確保されるので、客土層7の過剰水分を効率良く排出し、植物20の生育に適した水分量および通気性を維持できるほか、雨水などによる客土層7の流出を防止することができる。   Moreover, since the supporting member 1 in this embodiment is the thing in which the foamed glass 11 which has an open cell is filled in the cylindrical cage | basket | basket 10, it has a moderate clearance gap, the rain water which osmose | permeated the customer soil layer 7, etc. Can flow downward through this gap. In addition, since air permeability in the soil layer 7 is also secured, excess moisture in the soil layer 7 can be efficiently discharged, and the moisture amount and air permeability suitable for the growth of the plant 20 can be maintained. The outflow of the customer soil layer 7 due to the above can be prevented.

また、地盤2および支持部材1を覆うようにラス金網4を張設し、これらの上に基盤材6を吹き付け、硬化させて客土層7を形成するので、客土層7はきわめて強固に地盤2に固定され、客土層7で生育する植物20はラス金網4や支持部材1の筒状籠10に絡むように成長していくため、客土層7の流出や崩落、植物20の脱落などを有効に防止することができる。なお、地盤2の勾配が緩やかであり、地盤2に対する基盤材6の密着力も強いなどの施工条件が整えば、ラス金網4なしで客土層7を形成することも可能である。   Further, the lath wire mesh 4 is stretched so as to cover the ground 2 and the support member 1, and the base material 6 is sprayed and cured thereon to form the customer soil layer 7, so that the customer soil layer 7 is extremely strong. The plant 20 fixed on the ground 2 and growing on the soil layer 7 grows so as to be entangled with the lath wire mesh 4 and the cylindrical basket 10 of the support member 1. Dropout can be effectively prevented. If the construction conditions such as the gradient of the ground 2 is gentle and the adhesion of the base material 6 to the ground 2 is strong, the customer soil layer 7 can be formed without the lath wire mesh 4.

また、発泡ガラスの塊状体11および粒状体8は、その外周から内部に連続した気泡を有しているため、客土層7中において有益な土壌微生物などの住処となり、これらの働きによっても植物の生育が活性化される。さらに、塊状体11および粒状体8はいずれもガラス質であるため化学的に安定であり、有害物質の溶出や腐食なども生じないため、環境汚染のおそれがなく、耐久性にも優れている。   Moreover, since the lump body 11 and the granular body 8 of foam glass have continuous bubbles from the outer periphery to the inside thereof, they become a residence for beneficial soil microorganisms and the like in the soil layer 7, and planting is also performed by these functions. Is activated. Furthermore, since the lump 11 and the granule 8 are both glassy, they are chemically stable, and no leaching or corrosion of harmful substances occurs, so there is no risk of environmental pollution and excellent durability. .

さらに、本実施形態では、客土層7は、粒状体8、堆肥、植物種子、粘着材および化学肥料などを含有する基盤材6を地盤2上に吹き付けて硬化させることによって形成されているため、客土層7においては、基盤材6に含まれる粘着材により粒状体8、堆肥、植物種子などが互いに固結して団粒化構造が形成され、降雨などによる客土層7の浸食や、風による基盤材6の飛散などを防止することができる。   Further, in the present embodiment, the soil layer 7 is formed by spraying the base material 6 containing the granular material 8, compost, plant seeds, adhesive material, chemical fertilizer and the like on the ground 2 and curing it. In the soil layer 7, the granular material 8, compost, plant seeds and the like are solidified together by the adhesive material included in the base material 6 to form an aggregated structure. The scattering of the base material 6 due to wind can be prevented.

また、基盤材6に含まれる堆肥は、落ち葉、藁、塵芥、野草などを積み重ね、腐敗させて作った有機物質の混合物であり、客土層7に含有される植物種子が成長する際の養分供給源となるほか、保肥力の増強、保水性や通気性の改善、土壌微生物の活動促進などの作用があるため、良好な植物生育基盤を形成することができる。また、基盤材6に化学肥料を添加しているため、植物20の成長をさらに促進することができる。   Moreover, the compost contained in the base material 6 is a mixture of organic substances made by stacking fallen leaves, straw, dust, wild grass, etc., and rotted, and the nutrients when the plant seeds contained in the soil layer 7 grow. In addition to being a supply source, it has the effects of enhancing fertilizer retention, improving water retention and air permeability, and promoting the activity of soil microorganisms, so it can form a good plant growth base. Moreover, since the chemical fertilizer is added to the base material 6, the growth of the plant 20 can be further promoted.

また、客土層7は発泡ガラスの粒状体8を含有しているので、客土層7の内部に、植物20の根や芽などの生育に必要とされる隙間を確保することができ、工事完了後、発芽した植物種子は堆肥などに含まれる養分を吸収しながら客土層7の表面から外部へ順調に成長していき、緑豊かな緑化法面21を構築することができる。この粒状体8は、前述したように、多数の微小連続気泡を有する発泡ガラスで形成され、比較的軽量で、地下水や雨水などを適度に吸収し、余分な水分は透過する機能を備えているため、工事完了後、長期間経過しても、初期の軽量性が失われることがなく、客土層7の流出や崩落などを防止することができる。   Moreover, since the customer soil layer 7 contains the granular material 8 of foam glass, the clearance gap required for growth, such as a root of a plant 20, a bud, can be ensured inside the customer soil layer 7, After the completion of the construction, the germinated plant seeds grow smoothly from the surface of the soil layer 7 to the outside while absorbing nutrients contained in compost and the like, and a green planting slope 21 can be constructed. As described above, the granular material 8 is formed of foamed glass having a large number of minute open cells, is relatively lightweight, has a function of absorbing groundwater and rainwater appropriately, and transmitting excess water. Therefore, even after a long period of time has elapsed after completion of the construction, the initial lightweight property is not lost, and the outflow or collapse of the customer soil layer 7 can be prevented.

なお、発泡ガラスの塊状体11および粒状体8は、新たなガラス材で製造することができるが、本実施形態においては、廃棄された空瓶やガラス廃材などを原料として製造したものを使用しているため、資源の有効活用が図られ、ガラス廃材の不法投棄が減少し、自然環境の保護に寄与することができる。   In addition, although the lump body 11 and the granular material 8 of foam glass can be manufactured with a new glass material, in this embodiment, what was manufactured using the discarded empty bottle, the glass waste material, etc. as a raw material is used. Therefore, effective use of resources can be achieved, and illegal dumping of glass waste can be reduced, contributing to the protection of the natural environment.
