Abstract
Description
本発明は、例えば、法面などの緑化に用いられる緑化促進部材及び植生基体に関する。 The present invention relates to a greening promotion member and a vegetation base used for greening such as a slope.
植物の成長には水分が欠かせないが、法面の緑化を図る場合、法面の排水性は一般的に高いため、特に夏期など乾燥の影響を受けやすい時期に緑化用植物が水分不足に陥ることが多い。 Moisture is indispensable for plant growth, but when planting slopes, the slope drainage is generally high, so the planting plant becomes deficient, especially during the summer season when it is susceptible to drying. Often falls.
そこで、緑化用植物に対して必要な水分の補給を可能とすることを一つの目的とした植生基体が使用されている。例えば、特許文献１には、法面上に張設される網状体に、保水材を収容した袋を括りつけるようにした緑化用植生基体が開示されている。 Therefore, a vegetation substrate for the purpose of making it possible to supply water necessary for a plant for greening is used. For example, Patent Document 1 discloses a vegetation base for greening in which a bag containing a water retaining material is bound to a net-like body stretched on a slope.
これまで使用されていた特許文献１に示すような植生基体は、粒状の保水材（高分子吸収剤）を袋内に収容するものであり、袋に保水材を収容する手間が掛かり、安価ともいえない。また、保水材が袋内で偏ってしまうことも考えられ、その場合、水分補給が過多または過少となるエリアの発生、増大を招来する恐れがある。 The vegetation substrate as shown in Patent Document 1 used so far is for storing a granular water-retaining material (polymer absorbent) in a bag, and it takes time and trouble to store the water-retaining material in the bag. I can't say that. In addition, it is conceivable that the water retaining material is biased in the bag, and in this case, there is a risk that an area where water replenishment is excessive or insufficient may be generated or increased.
本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、均一的な給水を可能としながらも製造が容易であり安価な緑化促進部材及び植生基体を提供することにある。 The present invention has been made in consideration of the above-described matters, and an object of the present invention is to provide a greening promotion member and a vegetation base that are easy to manufacture and inexpensive while allowing uniform water supply.
上記目的を達成するために、本発明に係る緑化促進部材は、吸水性繊維を含む不織布によって形成され帯状または筒状を呈することを特徴としている（請求項１）。 In order to achieve the above object, the greening promotion member according to the present invention is formed of a non-woven fabric containing water-absorbing fibers and has a strip shape or a cylindrical shape (Claim 1).
上記緑化促進部材において、前記不織布はレーヨンを含んでいてもよい（請求項２）。 In the greening promoting member, the nonwoven fabric may contain rayon (claim 2).
上記緑化促進部材において、前記不織布は前記吸水性繊維よりも分解速度の遅い耐蝕性繊維を含んでいてもよい（請求項３）。 The said greening promotion member WHEREIN: The said nonwoven fabric may contain the corrosion-resistant fiber whose degradation rate is slower than the said water absorbing fiber (Claim 3).
上記緑化促進部材において、前記不織布はポリエステルを含んでいてもよい（請求項４）。 The said greening promotion member WHEREIN: The said nonwoven fabric may contain polyester (Claim 4).
一方、上記目的を達成するために、本発明に係る植生基体は、請求項１〜４の何れか一項に記載の緑化促進部材を装着する（請求項５）。 On the other hand, in order to achieve the above object, a vegetation substrate according to the present invention is equipped with the greening promotion member according to any one of claims 1 to 4 (claim 5).
本願発明では、均一的な給水を可能としながらも製造が容易であり安価な緑化促進部材及び植生基体が得られる。 In the present invention, a greening promoting member and a vegetation base that are easy to manufacture and inexpensive while allowing uniform water supply can be obtained.
すなわち、本願の各請求項に係る発明の緑化促進部材では、例えば不織布を帯状にカットするあるいは筒状に形成された不織布を所定長さ分カットするだけで容易に得られるものであり、安価なものとすることができる。また、粒状の保水材を収容した袋が装着される従来の植生基体では、袋内で保水材が偏り均一な給水が実現されない恐れがあるが、本発明の緑化促進部材では、粒状の保水材を用いず、帯状または筒状の不織布を用いるので、上記のような偏りは生じず、均一的な給水を確実に実現することができる。 That is, in the greening promotion member of the invention according to each claim of the present application, for example, the nonwoven fabric can be easily obtained simply by cutting the nonwoven fabric into a strip shape or by cutting the nonwoven fabric formed into a cylindrical shape by a predetermined length. Can be. Further, in the conventional vegetation base on which a bag containing granular water retention material is mounted, the water retention material may be unevenly distributed in the bag, and uniform water supply may not be realized. However, in the greening promotion member of the present invention, the granular water retention material Since a non-woven fabric is used and a strip-like or cylindrical nonwoven fabric is used, the above-described bias does not occur, and uniform water supply can be reliably realized.
請求項３、４に係る発明の緑化促進部材では、吸水性繊維と耐蝕性繊維との併用により、吸水機能とその機能の維持との両立を容易に図ることができる。 In the greening promotion member according to the third and fourth aspects of the present invention, it is possible to easily achieve both the water absorption function and the maintenance of the function by using the water absorbing fiber and the corrosion resistant fiber in combination.
本発明の実施の形態について図面を参照しながら以下に説明する。 Embodiments of the present invention will be described below with reference to the drawings.
図１に示す植生基体は、例えば横１ｍ×縦２０ｍの平面視長方形の植生マット１と、この植生マット１に装着される緑化促進部材２とを具備している。 The vegetation base shown in FIG. 1 includes, for example, a vegetation mat 1 that is 1 m wide × 20 m long and has a rectangular shape in plan view, and a greening promotion member 2 that is attached to the vegetation mat 1.
植生マット１は、ネット３の下面に植生シート４を重合してなるものである。ここで、ネット３の材質としては、年月の経過とともに土壌化する必要があるときは、天然繊維や生分解性プラスチックの繊維を使用し、表層土の流動や侵食防止効果を半永久的に確保したい場合には、ポリエチレン、ナイロン等の繊維を使用すればよい。 The vegetation mat 1 is formed by polymerizing the vegetation sheet 4 on the lower surface of the net 3. Here, as the material of the net 3, when it is necessary to turn into soil with the passage of time, natural fibers and biodegradable plastic fibers are used to ensure the effect of preventing surface soil flow and erosion semipermanently. If desired, fibers such as polyethylene and nylon may be used.
植生シート４は、スフ等の薄綿状シート４ａに、植生種子、肥料、土壌改良材等の植生基材４ｂを担持させたものである。薄綿状シート４ａは、シート状の薄綿（綿花を意味しているのではなく、薄い綿状のものを意味している）であることが望ましいが、不織布や紙のようなものであってもよく、この薄綿状シート４ａは植物の通芽や通根を妨げない程度の強度を有するものであり、その平均厚みを０．１〜１０ｍｍ、望ましくは、０．５〜５ｍｍに設定することで、浸食防止機能を有しながらも植物を地面に根付かせ易くすることができる。 The vegetation sheet 4 is obtained by supporting a vegetation base 4b such as vegetation seeds, fertilizers, and soil conditioners on a thin cotton sheet 4a such as sufu. The thin cotton-like sheet 4a is preferably a sheet-like thin cotton (not a cotton, but a thin cotton-like one), but it may be a non-woven fabric or paper. Well, this thin cotton-like sheet 4a has a strength that does not hinder plant sprouting and rooting, and its average thickness is set to 0.1 to 10 mm, preferably 0.5 to 5 mm. While having the function of preventing erosion, the plant can be easily rooted on the ground.
そして、ネット３と植生シート４とは積層状態で一体化されて植生マット１を構成するのであり、その一体化は、例えば植生シート４の薄綿状シート４ａの繊維をネット３に絡み付かせることによって行ってもよいし、ネット３と植生シート４とを少量の水溶性接着剤で接着することによって行ってもよく、両方の手段を併用するようにしてもよい。薄綿状シート４ａの繊維をネット３に絡み付かせる方法としては、ネット３と植生シート４とを積層した状態でローラ間に通して加圧することにより、薄綿状シート４ａの繊維をネット３に絡み付かせる方法や、薄綿状シート４ａ側から空気を吹きつけたり、ネット３側から空気を吸引したりすることにより、薄綿状シートの繊維をネット３側に起毛させてネット３に絡みつかせる方法が考えられる。 And the net | network 3 and the vegetation sheet | seat 4 are integrated in the lamination | stacking state, and the vegetation mat 1 is comprised, The integration is carried out by making the fiber of the thin cotton-like sheet | seat 4a of the vegetation sheet | seat 4 entangle with the net | network 3, for example. It may be performed by adhering the net 3 and the vegetation sheet 4 with a small amount of water-soluble adhesive, or both means may be used in combination. As a method of entwining the fibers of the thin cotton-like sheet 4a with the net 3, the fibers of the thin cotton-like sheet 4a are entangled with the net 3 by pressing between the rollers while the net 3 and the vegetation sheet 4 are laminated. It is conceivable to use a method or a method in which air is blown from the thin cotton-like sheet 4a side or air is sucked from the net 3 side so that fibers of the thin cotton-like sheet are raised on the net 3 side and entangled with the net 3.
また、ネット３には、緑化促進部材２を展張した状態で収容可能な筒状のポケット部５が長手方向に一定の間隔おきに形成されている。 Moreover, the cylindrical pocket part 5 which can be accommodated in the state which extended the greening promotion member 2 in the net | network 3 is formed in the longitudinal direction at fixed intervals.
緑化促進部材２は、吸水性繊維と、吸水性繊維よりも分解速度の遅い耐蝕性繊維とを含む不織布によって形成され帯状（例えば長さＬが１０５ｃｍで幅Ｗが５ｃｍの短冊状）を呈する部材である。そして、緑化促進部材２の長さＬを植生マット１のポケット部５の長さ（植生マット１の横幅）Ｘとほぼ同一長さとすることができ、本例では緑化促進部材２をポケット部５よりも若干長くしてある。 The greening promotion member 2 is a member formed of a non-woven fabric including water-absorbing fibers and corrosion-resistant fibers having a decomposition rate slower than that of the water-absorbing fibers and exhibiting a strip shape (for example, a strip shape having a length L of 105 cm and a width W of 5 cm). It is. The length L of the greening promotion member 2 can be made substantially the same as the length X of the pocket portion 5 of the vegetation mat 1 (the lateral width of the vegetation mat 1). In this example, the greening promotion member 2 is connected to the pocket portion 5. It is slightly longer than.
本例の緑化促進部材２を構成する不織布は、吸水性繊維としてレーヨンを６０％含み、耐蝕性繊維（非分解性繊維）としてのポリエステルを４０％含むものであり、目付けは１００〜３００ｇ／ｍ2 （特に１５０ｇ／ｍ2 位が好ましい）、厚みは２〜１０ｍｍとなっている。 The nonwoven fabric constituting the greening promotion member 2 of this example contains 60% rayon as a water-absorbing fiber, 40% polyester as a corrosion-resistant fiber (non-degradable fiber), and has a basis weight of 100 to 300 g / m. 2 (particularly 150 g / m 2 is preferable), and the thickness is 2 to 10 mm.
不織布を構成する吸水性繊維の比率が大きくなると、吸水（保水）機能が向上する反面、全体としての分解速度が速まり吸水機能を長期間維持することができなくなり、逆に耐蝕性繊維の比率が大きくなると、全体としての分解速度が遅くなり形状及び吸水機能は長期間維持されるが吸水機能は劣ることになる。従って、不織布を構成する吸水性繊維と耐蝕性繊維の比率は、吸水機能と機能維持との双方を満足することができる範囲で設定することが好ましい。 If the ratio of the water-absorbing fibers constituting the nonwoven fabric increases, the water absorption (water retention) function improves, but the overall decomposition rate increases and the water absorption function cannot be maintained for a long time. Conversely, the ratio of the corrosion-resistant fibers When becomes larger, the decomposition rate as a whole becomes slower and the shape and the water absorption function are maintained for a long time, but the water absorption function is inferior. Therefore, the ratio of the water-absorbing fibers and the corrosion-resistant fibers constituting the nonwoven fabric is preferably set within a range that can satisfy both the water absorption function and the function maintenance.
植生マット１に対する緑化促進部材２の装着は、例えば緑化促進部材２を植生マット１の各ポケット部５に一つずつ挿入し、その両端をステープラー（図示していない）で植生マット１に連結することによって行うことができる。 The greening promotion member 2 is attached to the vegetation mat 1 by, for example, inserting the greening promotion member 2 into each pocket 5 of the vegetation mat 1 and connecting both ends thereof to the vegetation mat 1 with a stapler (not shown). Can be done.
上記のように構成される植生基体を例えば法面緑化に用いる場合には、各ポケット部５が法面の等高線にほぼ沿うように植生基体を法面上に配置し、アンカーピン等の適宜の部材で固定すればよい。そして、この場合、植生基体は、法面における凹凸に対応して柔軟に変形できる程度の柔軟性を有するものであることが望ましい。また、植生シート４は、雨水などを吸収することにより、ネット３から速やかに離脱し、地表面に密着するように構成してあることが望ましい。 When the vegetation substrate constructed as described above is used for, for example, slope greening, the vegetation substrate is arranged on the slope so that each pocket portion 5 is substantially along the contour line of the slope, and an appropriate pin such as an anchor pin is used. What is necessary is just to fix with a member. In this case, it is desirable that the vegetation base is flexible enough to be deformed flexibly corresponding to the irregularities on the slope. Moreover, it is desirable that the vegetation sheet 4 is configured to quickly detach from the net 3 and adhere to the ground surface by absorbing rainwater and the like.
ここで、法面に植生基体を設置する場合、展開した植生基体に占める緑化促進部材２の面積比率（設置率）は、１ｍ2 当たり０．０５〜０．８ｍ2 （より好ましくは、０．１〜０．５ｍ2 ）の範囲とすることが好ましい。上記範囲を下回ると緑化促進部材２による緑化（植生）促進効果が乏しくなり、上回ると十分な緑化面積の確保が困難となる。また、上記範囲を本例の緑化促進部材２（長さＬが１０５ｃｍで幅Ｗが５ｃｍの短冊状とした場合）に当て嵌めると、１ｍ2 当たり１〜１６本程度（より好ましくは２本〜１０本程度）設けることになるが、緑化促進部材２の取付けに掛かる手間等も考慮すると、１ｍ2 当たり２〜５本程度とすることが最も好ましい。そして、緑化促進部材２の設置率を調節するには、緑化促進部材２の長さＬ、幅Ｗ、植生マット１におけるポケット部５の配置（隣り合うポケット部５、５の間隔）や数等を調節すればよいことはいうまでもない。 Here, when the vegetation base is installed on the slope, the area ratio (installation rate) of the greening promotion member 2 in the developed vegetation base is 0.05 to 0.8 m 2 per 1 m 2 (more preferably, 0. 1 to 0.5 m 2 ) is preferable. If it is below the above range, the greening (vegetation) promoting effect by the greening promotion member 2 becomes poor, and if it exceeds the above range, it is difficult to secure a sufficient greening area. Further, when the above range is applied to the greening promotion member 2 of this example (when the length L is 105 cm and the width W is 5 cm), about 1 to 16 per 1 m 2 (more preferably 2 to 2). However, it is most preferable to set the number to about 2 to 5 per 1 m 2 in consideration of the labor required for mounting the greening promotion member 2. And in order to adjust the installation rate of the greening promotion member 2, the length L and width W of the greening promotion member 2, arrangement | positioning of the pocket part 5 in the vegetation mat 1 (space | interval of the adjacent pocket parts 5, 5), the number, etc. Needless to say, it is only necessary to adjust this.
上記の構成からなる緑化促進部材２は、例えば不織布を帯状（短冊状）にカットするだけで容易に得られるものであり、安価なものとすることができる。また、粒状の保水材を収容した袋が装着される従来の植生基体では、袋内で保水材が偏り均一な給水が実現されない恐れがあるが、本実施形態の緑化促進部材２では、粒状の保水材を用いず、帯状の不織布を用いるので、上記のような偏りは生じず、均一的な給水を確実に実現することができる。 The greening promotion member 2 having the above-described configuration can be easily obtained by simply cutting a nonwoven fabric into a strip shape (strip shape), for example, and can be inexpensive. Moreover, in the conventional vegetation base | substrate with which the bag which accommodated the granular water retention material is mounted | worn, there is a possibility that a water retention material may be biased in a bag and uniform water supply may not be implement | achieved, but in the greening promotion member 2 of this embodiment, granular Since a band-shaped non-woven fabric is used without using a water retaining material, the above-described bias does not occur, and uniform water supply can be reliably realized.
そして、上記の緑化促進部材２を用いる本実施形態の植生基体は、図１に示すように、植生マット１のポケット部５によって緑化促進部材２を安定性良く保持して、緑化促進部材２による均一的な給水を確実に行わせることができる。 And the vegetation base | substrate of this embodiment using said greening promotion member 2 hold | maintains the greening promotion member 2 with stability by the pocket part 5 of the vegetation mat 1, as shown in FIG. Uniform water supply can be performed reliably.
なお、本発明は、上記の実施の形態に何ら限定されず、本発明の要旨を逸脱しない範囲において種々に変形して実施し得ることは勿論である。例えば、以下のような変形例を挙げることができる。 In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.
緑化促進部材２は帯状（短冊状）のものに限られず、例えば筒状（平面視帯状）を呈するものや、１枚の帯（あるいは短冊）を折り畳んだもの等であってもよい。 The greening promotion member 2 is not limited to a belt-shaped (strip-shaped) member, and may be, for example, a tube-shaped (strip-shaped strip) or a folded one strip (or strip).
緑化促進部材２の不織布を構成する吸水性繊維には、レーヨン以外に、再生セルロース繊維、綿、ウール、やし繊維などを用いることができ、耐蝕性繊維には、ポリエステル以外のポリプロピレン、ポリエチレン等の非分解性繊維、ポリ乳酸繊維等の生分解性プラスチック繊維、羊毛等の動物性繊維、やし繊維や竹繊維等の強度のある植物性繊維などを用いることができる。やし繊維は、吸水性繊維としても耐蝕性繊維としても用いることができるので、不織布をやし繊維のみから構成してもよい。また、吸水性繊維あるいは耐蝕性繊維の少なくとも何れか一方を２種以上用いるようにしてもよい。 In addition to rayon, regenerated cellulose fiber, cotton, wool, palm fiber and the like can be used as the water-absorbing fiber constituting the nonwoven fabric of the greening promotion member 2, and polypropylene, polyethylene, etc. other than polyester can be used as the corrosion-resistant fiber. Nondegradable fibers, biodegradable plastic fibers such as polylactic acid fibers, animal fibers such as wool, and strong plant fibers such as palm fibers and bamboo fibers can be used. Since the palm fiber can be used as both a water-absorbing fiber and a corrosion-resistant fiber, the non-woven fabric may be composed only of palm fiber. Further, at least one of water-absorbing fibers and corrosion-resistant fibers may be used.
また、緑化促進部材２を、吸水性繊維のみからなる不織布によって形成してもよく、例えば、レーヨン１００％の不織布を用いて緑化促進部材２を形成してもよい。 Moreover, the greening promotion member 2 may be formed of a non-woven fabric composed only of water-absorbing fibers. For example, the greening promotion member 2 may be formed using a non-woven fabric of 100% rayon.
上記実施形態では、緑化促進部材２を構成する不織布の目付けを１００〜３００ｇ／ｍ2としているが、これに限らず、不織布を構成する繊維によって１００〜９００ｇ／ｍ2 の範囲で設定すればよく、例えばレーヨン１００％の不織布を用いる場合には、目付量を８５０ｇ／ｍ2 程度とすることが考えられる。 In the above embodiment, although the basis weight of the nonwoven fabric constituting the greening promoting member 2 and 100 to 300 g / m 2, not limited thereto, it may be set by the fibers constituting the nonwoven fabric in the range of 100~900g / m 2 For example, when using a 100% rayon nonwoven fabric, the basis weight may be about 850 g / m 2 .
植生シート４の薄綿状シート４ａとして、例えば吸水性に優れた素材であるレーヨンからなる繊維に、耐蝕性のある素材であるポリ乳酸繊維（例えば商品名「ラクトロン」などの生分解性プラスチック）からなる繊維をそれぞれ５０％ずつの割合で混合したものや、この混合の比率を変えることにより薄綿状シート４ａが所望の分解速度で分解し、かつ、所望の吸水性を有するものとしたものを用いるようにしてもよく、薄綿状シート４ａを構成する繊維の素材は種々に変更可能である。 The thin vegetative sheet 4a of the vegetation sheet 4 is made of, for example, a fiber made of rayon, which is a material with excellent water absorption, and a polylactic acid fiber (for example, a biodegradable plastic such as “Lactron”, which is a corrosion-resistant material). It is preferable to use fibers in which the fibers are mixed at a ratio of 50%, or those in which the thin cotton sheet 4a is decomposed at a desired decomposition rate and has a desired water absorption by changing the mixing ratio. The material of the fibers constituting the thin cotton sheet 4a can be variously changed.
上記実施形態では、ステープラーによって緑化促進部材２を植生マット１に取り付けているが、植生マット１に対する緑化促進部材２の装着方法はこれに限らない。例えば、緑化促進部材２をポケット部５よりも長めに形成し、緑化促進部材２をポケット部５に挿入したときにポケット部５の両端から緑化促進部材２の両端がはみ出すようにし、はみ出した部分を植生マット１の下面側に折り返して植生マット１の下側に敷きこむようにしてもよい。 In the said embodiment, although the greening promotion member 2 is attached to the vegetation mat 1 with the stapler, the mounting method of the greening promotion member 2 with respect to the vegetation mat 1 is not restricted to this. For example, the greening promotion member 2 is formed to be longer than the pocket portion 5, and when the greening promotion member 2 is inserted into the pocket portion 5, both ends of the greening promotion member 2 protrude from both ends of the pocket portion 5. May be folded back to the lower surface side of the vegetation mat 1 and laid on the lower side of the vegetation mat 1.
上記実施形態では、ネット３にポケット部５を設け、ポケット部５に緑化促進部材２を挿入し取り付けるようにしているが、これに限らず、例えば、ネット３と植生シート４とを一体化して植生マット１を形成する際に、ネット３と植生シート４の間に緑化促進部材２を挟み込んだ状態としておき、緑化促進部材２が当初から植生マット１と一体化されているようにしてもよい。 In the said embodiment, although the pocket part 5 was provided in the net | network 3, and the greening promotion member 2 was inserted and attached to the pocket part 5, it is not restricted to this, For example, the net | network 3 and the vegetation sheet | seat 4 are integrated. When the vegetation mat 1 is formed, the greening promotion member 2 may be sandwiched between the net 3 and the vegetation sheet 4 so that the greening promotion member 2 is integrated with the vegetation mat 1 from the beginning. .
