Description

【０００１】
【発明の属する技術分野】
本発明は、植物苗を法面に吹き付けるための植物苗の送付機及びそれを使用した法面の緑化方法に関するものである。
【０００２】
【従来の技術】
掘削して地盤が露出した法面や、コンクリート、モルタル若しくは岩盤等の硬質法面を緑化する方法には、次のような工法がある。
例えば、法面を草本類で緑化する方法としては、法面上に金網などを敷設してその上から草本類の種子を混合した植生基材を吹き付ける方法がある。また、法面勾配が急傾斜である場合や植生基材を厚く設置する場合などに、法面上にコンクリート製の法枠を構築し、その枠内に植生基材を充填し、木本類や草本類を育成して緑化する方法もある。また、木本類を法面に植栽する場合は、ポケット状の植栽用空間を構築してその中に木本類の苗木を植栽する方法もある。
しかし、以上に述べた方法の中で植生基材に種子を混合する方法では、種子の発芽率が悪かったり、生育までに時間がかかったりするため、緑化による早期の法面保護が充分におこなえているとはいえない。また、施工後から緑化法面が形成されるまでの時間が長いため、長期間緑化されていない法面が出現することになり、景観上、好ましくない。さらに、安価に入手でき、植生基材と一緒に吹き付けても生育が期待できる植物の種子は限られており、緑化植物の選択の幅が狭い。また、苗木を植栽する方法は、植栽を人力でおこなうことになるため労力がかかる。
【０００３】
そこで、早期に法面を緑化するために、２節以上を有するノシバ等の匍匐茎の芝茎を植生基材に混合して吹き付ける方法が発案されている。特許文献１には、発芽済みの植物苗を植生基材と混合して吹き付けることによって、植物苗を痛めることなく法面に吹き付けることができるという噴射式植付緑化装置が開示されている。

【本発明が解決しようとする課題】
しかし、植物苗（ちぎり苗）を植生基材と混合して吹き付けた場合、植物苗が圧密されて植生基材の内部に埋没し、植物苗が生育できないことが多い。
また、植物苗を植生基材と撹拌・混合したときに、植生基材の砂質分等によって植物苗が磨耗されて傷つくことも多い。このように損傷した植物苗を法面に吹き付けたとしても、順調に生育する植物苗の割合は少ない。
【０００６】
【本発明の目的】
本発明は上記したような従来の問題を解決するためになされたもので、植物苗（ちぎり苗）と植生基材の同時搬送時間を抑え、吐出口で混合することにより、植物苗を損傷することなく法面まで搬送できる植物苗の送付機及びそれを使用した法面の緑化方法を提供することを目的とする。
また、吹き付けた植物苗が順調に発育可能な植物苗の送付機及びそれを使用した法面の緑化方法を提供することを目的とする。
さらに法面を早期に緑化でき、また従来はコンクリートで被覆されていた道路側面の防火帯に常緑多肉質の難燃性植物層を育成することにより、耐火性が高く景観に優れた道路空間を確保できる法面の緑化方法を提供することを目的とする。
本発明は、これらの目的の少なくとも一つを達成するものである。
【０００７】
【課題を解決するための手段】
上記のような目的を達成するために、本発明の植物苗の送付機は、植物苗を一時的に格納する下方が開口したホッパーと、前記ホッパーの開口部から吐出した前記植物苗を撹拌しながら搬送する撹拌搬送装置と、前記撹拌搬送装置から送り出された前記植物苗を法面まで圧縮空気と共に搬送する送付ホースと、からなるものである。
また、前記撹拌搬送装置から送り出された後に、風圧によって吹き飛ばされた前記植物苗を搬送する接続ホースを、前記撹拌搬送装置と前記送付ホースの間に配置することもできる。この場合、前記接続ホースの内径よりも前記送付ホースの内径の方を大きくするのが好ましい。
また、植物苗の送付機には、前記植物苗の供給量を調節する供給調節装置を設けることもできる。
【０００８】
次に、本発明の植物苗の送付機を使用した法面の緑化方法は、所定の間隔で法面から突出する植生基材受材を設置し、上記のいずれかに記載の植物苗の送付機によって供給された植物苗と、吹付けホースによって搬送された植生基材を法面に同時に吹き付けることを特徴とする方法である。ここで、前記植生基材受材として矩形の有孔板を使用し、法面方向に所定の間隔を開けて前記植生基材受材を横方向に配置し、前記植生基材受材を支持材で固定することができる。
【０００９】
【本発明の実施の形態】
以下、図面を参照しながら本発明の実施の形態について説明する。
【００１０】
＜イ＞植物苗の送付機
植物苗の送付機１は、植物苗６を搬送し法面に送付するための装置である。
送付機１は、植物苗６を一時的に格納するホッパー２と、ホッパー２の開口部から吐出した植物苗を撹拌しながら搬送する撹拌搬送装置３と、撹拌搬送装置３から送り出された植物苗６を法面９まで圧縮空気と共に搬送する送付ホース４とから構成する。
ホッパー２は、下方に開口部を有し、一時的に格納した植物苗６を徐々に開口部から吐出して供給する。ホッパー２の内部には撹拌翼を設けておいて投入した植物苗６を撹拌しながら供給することもできる。撹拌搬送装置３は、例えば回転軸周りに螺旋翼を取り付けたスクリューで構成する。ホッパー２の開口部から吐き出された植物苗６は、撹拌搬送装置３のスクリューによって撹拌されながら横方向に搬送される。このため、植物苗６が塊になり難く、開口部から落下した塊状の植物苗６もほぐされながら搬送される。なお、ホッパー２の開口部に開閉式の扉を付けて扉の開閉を制御したり、撹拌搬送装置３の回転速度や稼動及び停止を制御したりする供給調節装置２１を設けることで、植物苗６の供給量を調節することができる。
【００１１】
撹拌搬送装置３で所定の位置まで横移動した植物苗６を、例えば漏斗状の受け口５２に放出する。そして、受け口５２に落ちた植物苗６は、送風ノズル５１から噴射される風の圧力によってばらばらになりながら接続ホース５に送り込まれる。接続ホース５は、撹拌搬送装置３と後述する送付ホース４を繋ぐホースであって、省略することもできる。
送付ホース４は、植物苗６を法面９まで搬送するホースであって、後方はコンプレッサー等に接続されている。そして、コンプレッサーから送り出された圧縮空気４１の流れに乗せて植物苗６を搬送する。送付ホース４の内径は、その側面に接続する接続ホース５の内径よりも大きいものにするのが好ましい。接続ホース５の内径よりも送付ホース４の内径を大きくすることで、送付ホース４に植物苗６が吸込まれ易くなる。例えば、接続ホース５の内径を３０ｍｍにした場合、送付ホース４の内径を６０ｍｍにする。
【００１２】
＜ロ＞植物苗
植物苗６には、セダム類植物の苗、発芽済みの植物、２節以上を有する匍匐茎の芝茎などが該当する。
セダム類植物は、ベンケイソウ科キリンソウ属の園芸植物をいう。セダム類植物は、北半球の温帯ないし亜寒帯に広く分布するほか南アメリカにもあって約四〇〇種ある。日本にもキリンソウ、メノマンネングサ、イワレンゲなど約三〇種が自生する。また、メキシコマンネングサ、オノマンネングサ、ツルマンネングサ、サカサマンネングサ、アルブム、スプリューム、オオベンケイソウ、ヨーロッパベンケイソウなど多種が栽培されている。一般的には多年生、稀に一年生の多肉植物で、耐乾性が強く繁殖力が旺盛である。しかし、セダム類植物の種子は入手困難でかつ高価なため、生長したセダム類植物の一部をちぎって３〜４日自然乾燥させた苗（かかる苗をちぎり苗という）又は生育苗が緑化用に使用されている。
【００１３】
＜ハ＞植生基材
植生基材７は、植物が生育に必要とする基盤材料をいう。通常は、土と肥料を混合したものをいう。ここでは、土として現地発生土、土砂、砂、シラス等が使用できる。また、肥料としてはバーク堆肥等が使用できる。
セダム類植物を使用する場合は、肥料を混合する量を通常の草本類に必要な量より少なくすることができる。また、現地発生土等を使用する場合であって土自体に植物苗６の育成に必要な栄養分が含まれている場合は、別途肥料を混合しなくても良い。
なお、セダム類植物の種子等の植物の種子を植生基材７に混合して一緒に吹付けても良い。
【００１４】
＜ニ＞植生基材受材
植生基材受材８１は、植生基材７を法面９に定着させるために用いる。植生基材受材８１は、法面から突出し、法面９から植生基材７が滑り落ちることを防ぐものであれば良い。特に、急勾配法面（１：０．６〜１：０．３）においては、植生基材受材８１を配置するのが好ましい。
例えば、矩形の有孔板を植生基材受材８１に使用する。有孔板としては、金網、樹脂製ネット等が使用できる。有孔板であれば、法面方向の水の流れを遮断することもなく、植物の根系の伸長を妨げることもない。また、紙製の有孔板を使用することもできる。この場合、年月の経過と共に植生基材受材８１が腐食し、植生基材７と一体化する。
植生基材受材８１は、法面９に支持材８２で固定する。支持材８２としては、例えばアンカーピン、鉄筋、ロックボルト等が使用できる。
【００１５】
以下に、図３を参照しながら植物苗の送付機を使用した法面の緑化方法について述べる。
【００１６】
＜イ＞適用法面
植物苗の送付機１によって搬送された植物苗６は法面９に吹き付けられる。ここで、法面９には地山を掘削して発生した切土法面や盛土によって発生した盛土法面の他に、急勾配（１：０．６〜１：０．３）の既設コンクリート若しくはモルタル吹付け法面、又は岩盤法面も含まれる。
コンクリート若しくはモルタル吹付け法面、又は岩盤法面等の硬質法面の表層に植生基盤を設けた場合、一般に、法面９から植生基盤への地下水等の供給はなく、植生基盤で生育した植物もその根系を法面内部にまで伸長させることは難しい。また、法面の温度が高温になり乾燥し易く、導入した植物は枯死する。このため硬質法面には、植生基材受材８１を使用して厚く植生基材７を吹き付けて植生基盤を形成するか、若しくは耐暑性に優れたセダム類植物を吹き付けるのが好ましい。
【００１７】
＜ロ＞植生基材受材の設置
植生基材受材８１を法面９の横方向に設置する。ここで、植生基材受材８１は横方向に連続していても、断続的に設置されていても良い。断続的に設置する場合は、例えば千鳥配置とする。図３は横方向に連続して植生基材受材８１を設置した状態を示した図である。
植生基材受材８１は、例えば法面９に垂直に立てて配置し、転倒しないようにアンカーピン等の支持材８２で固定する。
【００１８】
＜ハ＞植物苗及び植生基材の吹付け
植生基材７は、コンプレッサーに接続したモルタル吹付け機、又は客土吹付け機等によって吹付けホース７１内を搬送し、法面９に吹き付ける。
吹付けホース７１の先端付近には、植物苗６を搬送する送付ホース４の先端付近を添わせて配置し、植生基材７と植物苗６を吐出口で混合して一緒に法面９に吹き付けることができるように構成するのが好ましい。
本発明では、植物苗６を植生基材７とは別のルートで搬送することで植物苗６と植生基材７の同時搬送時間を抑えることができるため、吐出口に至るまでの搬送中に植物苗６が植生基材７と擦れて損傷することがない。また、植物苗６を植生基材７と吐出口で混合して同時に吹き付けることによって、植物苗６が植生基材７に埋没することがない上に、吹き付けられた植生基材７の表層に定着するように植物苗６を配置することができる。すなわち、植生基材７を吹き付けた後に植物苗６を吹き付けた場合は、充分に植物苗６を定着させることが難しいため、別のルートで搬送した植物苗６と植生基材７を同時に吹き付けるのが好ましい。この場合、植物苗６が植生基材７よりも上に配置されるように、送付ホース４を吹付けホース７１よりも上に配置するなどの調整をすることができる。
吹付けは、少なくとも植生基材受材８１の上端が隠れる厚さとなるまで行う。
【００１９】
【本発明の効果】
本発明の植物苗の送付機及びそれを使用した法面の緑化方法は、以上説明したようになるから次のような効果を得ることができる。
＜イ＞植物苗を損傷させることなく搬送することができる。このため、良好な状態で植物苗が法面に吹き付けられ、吹き付けられた多くの植物苗が効率よく順調に発育することができる。
＜ロ＞植物苗と植生基材を別のルートで搬送して同時に法面に吹き付ける。このため、植物苗が植生基材に埋れることがない上に、植生基材に確実に定着させることもできる。
＜ハ＞自然環境の保全・再生という観点から、既設モルタルや既設コンクリート斜面からの反射熱を抑制することによって地球温暖化防止に寄与できるとともに自然景観及び快適な道路空間を創出することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a plant seedling sending machine for spraying plant seedlings on a slope, and a slope greening method using the same.
[0002]
[Prior art]
There are the following methods for greening the slope where the ground is exposed by excavation and the hard slope such as concrete, mortar or rock.
For example, as a method of greening the slope with herbs, there is a method of laying a wire net or the like on the slope and spraying a vegetation base mixed with herbaceous seeds thereon. In addition, when the slope of the slope is steep or when the vegetation base is thickly installed, a concrete frame is constructed on the slope, and the vegetation base is filled in the frame. There is also a method to cultivate and plant herbs. In addition, when planting trees on a slope, there is a method of constructing a pocket-shaped planting space and planting tree seedlings therein.
However, among the methods described above, the method of mixing seeds with the vegetation base material has poor seed germination rate and takes time to grow, so that early slope protection by greening can be sufficiently performed. I cannot say that. Moreover, since it takes a long time until the greening slope is formed after the construction, a slope that has not been greened for a long time appears, which is not preferable in view of the landscape. Furthermore, the seeds of plants that can be obtained at low cost and can be expected to grow even when sprayed with a vegetation base are limited, and the range of green plant selection is narrow. In addition, the method of planting seedlings requires labor since planting is done manually.
[0003]
Therefore, in order to green the slope at an early stage, a method has been devised in which turf shoots such as barbs having two or more nodes are mixed and sprayed on a vegetation substrate. Patent Document 1 discloses a spray-type planting planting device that can spray a plant seedling that has been germinated with a vegetation base material and spray it onto a slope without damaging the plant seedling.
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 11-123007
[Problems to be solved by the present invention]
However, when plant seedlings (chigiri seedlings) are mixed and sprayed with a vegetation base material, the plant seedlings are often compacted and buried inside the vegetation base material, and the plant seedlings often cannot grow.
In addition, when a plant seedling is agitated and mixed with a vegetation base material, the plant seedling is often worn and damaged by the sandy content of the vegetation base material. Even if the plant seedling damaged in this way is sprayed on the slope, the ratio of the plant seedling growing smoothly is small.
[0006]
[Object of the present invention]
The present invention has been made to solve the conventional problems as described above, and suppresses the simultaneous conveyance time of the plant seedling (chigiri seedling) and the vegetation base material, and damages the plant seedling by mixing at the discharge port. An object of the present invention is to provide a plant seedling sending machine that can be transported to a slope without any problem and a method of planting a slope using the same.
It is another object of the present invention to provide a plant seedling sending machine capable of growing the sprayed plant seedlings smoothly, and a slope greening method using the same.
Furthermore, the slopes can be planted early, and the road space that has high fire resistance and excellent scenery can be obtained by cultivating an evergreen fleshy flame-retardant plant layer in the fireside zone of the road side that was conventionally covered with concrete. The purpose is to provide a method for greening the slope that can be secured.
The present invention achieves at least one of these objects.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the plant seedling sending machine according to the present invention stirs the hopper with a lower opening that temporarily stores the plant seedling and the plant seedling discharged from the opening of the hopper. The agitating and conveying apparatus that conveys the medium while conveying the plant seedlings fed from the agitating and conveying apparatus to the slope with compressed air.
In addition, a connection hose that conveys the plant seedling blown out by wind pressure after being sent out from the stirring and conveying device can be disposed between the stirring and conveying device and the sending hose. In this case, it is preferable to make the inner diameter of the sending hose larger than the inner diameter of the connection hose.
Further, the plant seedling sending machine may be provided with a supply control device for adjusting the amount of plant seedling supplied.
[0008]
Next, in the method of planting the slope using the plant seedling sending machine of the present invention, a vegetation base receiving material protruding from the slope at predetermined intervals is installed, and the plant seedling sending according to any one of the above The plant seedling supplied by the machine and the vegetation base material conveyed by the spray hose are sprayed simultaneously on the slope. Here, a rectangular perforated plate is used as the vegetation substrate receiving material, the vegetation substrate receiving material is arranged in a lateral direction with a predetermined interval in the slope direction, and the vegetation substrate receiving material is supported. Can be fixed with material.
[0009]
[Embodiments of the Invention]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
<I> Plant seedling sending machine The plant seedling sending machine 1 is an apparatus for conveying the plant seedling 6 and sending it to the slope.
The sending machine 1 includes a hopper 2 that temporarily stores the plant seedling 6, a stirring and conveying device 3 that conveys the plant seedling discharged from the opening of the hopper 2 while stirring, and a plant seedling that is sent from the stirring and conveying device 3. 6 is composed of a sending hose 4 that conveys 6 to the slope 9 with compressed air.
The hopper 2 has an opening at the lower side, and the plant seedling 6 temporarily stored is gradually discharged and supplied from the opening. It is also possible to provide a stirring blade in the hopper 2 and supply the plant seedling 6 that has been introduced while stirring. The agitation transport device 3 is constituted by, for example, a screw having a spiral blade attached around a rotation axis. The plant seedling 6 discharged from the opening of the hopper 2 is conveyed in the lateral direction while being stirred by the screw of the stirring and conveying device 3. For this reason, the plant seedling 6 does not easily become a lump, and the lump-like plant seedling 6 dropped from the opening is conveyed while being loosened. In addition, by attaching a door that can be opened and closed to the opening of the hopper 2 to control the opening and closing of the door, and to provide a supply adjusting device 21 that controls the rotation speed, operation and stop of the stirring and conveying device 3, a plant seedling is provided. The supply amount of 6 can be adjusted.
[0011]
The plant seedling 6 that has been laterally moved to a predetermined position by the agitating and conveying device 3 is discharged to, for example, a funnel-shaped receiving port 52. Then, the plant seedling 6 that has fallen into the receiving port 52 is fed into the connection hose 5 while being separated by the pressure of the wind sprayed from the blower nozzle 51. The connection hose 5 is a hose that connects the agitation transport device 3 and a sending hose 4 described later, and can be omitted.
The sending hose 4 is a hose that conveys the plant seedling 6 to the slope 9, and the rear is connected to a compressor or the like. And the plant seedling 6 is conveyed in the flow of the compressed air 41 sent out from the compressor. The inner diameter of the sending hose 4 is preferably larger than the inner diameter of the connection hose 5 connected to the side surface. By making the inner diameter of the sending hose 4 larger than the inner diameter of the connection hose 5, the plant seedling 6 is easily sucked into the sending hose 4. For example, when the inner diameter of the connection hose 5 is 30 mm, the inner diameter of the sending hose 4 is 60 mm.
[0012]
<B> Plant seedlings Plant seedlings 6 include sedum plant seedlings, germinated plants, turf turf stalks having two or more nodes, and the like.
A sedum plant refers to a horticultural plant belonging to the genus Giraffe. Sedum plants are widely distributed in the temperate and subarctic regions of the northern hemisphere, and there are about 400 species in South America. In Japan, about 30 species such as giraffes, menamanengusa and iwarenge grow naturally. In addition, various species are cultivated, such as Mexican prunus, Onomanengusa, Tsurumanengusa, Sakasamanengususa, Arbumu, Sprume, Papilio japonica, and European peonies. In general, it is a perennial, rarely an annual succulent plant that has strong drought tolerance and strong fertility. However, because seeds of sedum plants are difficult to obtain and expensive, seedlings that have been naturally dried for 3 to 4 days after tearing off some of the grown sedum plants (such seedlings are called tearing seedlings) or growing seedlings are used for greening. Is used.
[0013]
<C> Vegetation base material The vegetation base material 7 refers to a base material that a plant needs for growth. Usually, it is a mixture of soil and fertilizer. Here, locally generated soil, earth and sand, sand, shirasu and the like can be used as the soil. Moreover, bark compost etc. can be used as a fertilizer.
When using sedum plants, the amount of fertilizer mixed can be less than that required for normal herbs. Further, when locally generated soil or the like is used and the soil itself contains nutrients necessary for growing the plant seedling 6, it is not necessary to separately mix fertilizer.
In addition, seeds of plants such as seeds of sedum plants may be mixed with the vegetation base material 7 and sprayed together.
[0014]
<D> Vegetation base material receiving material The vegetation base material receiving material 81 is used for fixing the vegetation base material 7 to the slope 9. The vegetation base material 81 may be any material that protrudes from the slope and prevents the vegetation base 7 from sliding down from the slope 9. In particular, it is preferable to arrange the vegetation base material 81 on a steep slope (1: 0.6 to 1: 0.3).
For example, a rectangular perforated plate is used for the vegetation base material receiving material 81. As the perforated plate, a wire net, a resin net, or the like can be used. If it is a perforated plate, it will not block the flow of water in the direction of the slope and will not hinder the growth of the root system of the plant. A paper perforated plate can also be used. In this case, the vegetation base material receiving material 81 is corroded with the passage of time and integrated with the vegetation base material 7.
The vegetation base material 81 is fixed to the slope 9 with a support material 82. As the support member 82, for example, an anchor pin, a reinforcing bar, a lock bolt, or the like can be used.
[0015]
Hereinafter, a method for planting a slope using a plant seedling sending machine will be described with reference to FIG.
[0016]
<I> The plant seedling 6 conveyed by the sending device 1 of the applied slope plant seedling is sprayed on the slope 9. Here, in addition to the cut slope generated by excavating the natural ground and the bank slope generated by embankment, the existing concrete with a steep slope (1: 0.6 to 1: 0.3) is included in the slope 9. Or a mortar spray slope or a rock slope is also included.
When a vegetation base is provided on the surface of a hard slope such as a concrete or mortar spray slope or a rock slope, there is generally no supply of groundwater from the slope 9 to the vegetation base, and plants grown on the vegetation base However, it is difficult to extend the root system into the slope. In addition, the slope temperature becomes high and it is easy to dry, and the introduced plant dies. For this reason, it is preferable that the vegetation base material 7 is sprayed thickly on the hard slope to form a vegetation base, or a sedum plant having excellent heat resistance is sprayed.
[0017]
<B> Installation of Vegetation Substrate Receiver The vegetation substrate receiver 81 is installed in the lateral direction of the slope 9. Here, the vegetation base material 81 may be continuous in the lateral direction or may be intermittently installed. In the case of intermittent installation, for example, a staggered arrangement is used. FIG. 3 is a view showing a state in which the vegetation base material receiving material 81 is continuously installed in the horizontal direction.
The vegetation base material receiving material 81 is, for example, arranged perpendicularly to the slope 9 and fixed with a support material 82 such as an anchor pin so as not to fall.
[0018]
<C> Spraying plant seedling and vegetation base material The vegetation base material 7 is transported through the spray hose 71 by a mortar spraying machine connected to a compressor, or a soil spraying machine, and sprayed on the slope 9.
In the vicinity of the tip of the spray hose 71, the vicinity of the tip of the sending hose 4 that conveys the plant seedling 6 is arranged, and the vegetation base material 7 and the plant seedling 6 are mixed together at the discharge port to the slope 9 together. It is preferable to be configured so that it can be sprayed.
In the present invention, since the plant seedling 6 is transported by a route different from that of the vegetation base material 7, the simultaneous transport time of the plant seedling 6 and the vegetation base material 7 can be suppressed. The plant seedling 6 is not damaged by rubbing against the vegetation base material 7. Further, the plant seedling 6 is mixed with the vegetation base material 7 at the discharge port and sprayed at the same time, so that the plant seedling 6 is not buried in the vegetation base material 7 and is fixed to the surface layer of the sprayed vegetation base material 7. The plant seedling 6 can be arranged to do so. That is, when the plant seedling 6 is sprayed after spraying the vegetation base material 7, it is difficult to sufficiently fix the plant seedling 6, so the plant seedling 6 and the vegetation base material 7 conveyed by another route are sprayed simultaneously. Is preferred. In this case, adjustments such as arranging the sending hose 4 above the blowing hose 71 so that the plant seedling 6 is arranged above the vegetation base material 7 can be performed.
The spraying is performed until at least the thickness of the upper end of the vegetation base material receiving member 81 is hidden.
