Description

【0001】
【発明の属する技術分野】
本発明は、法面に植生基盤を定着させて法面上に植生を図るための工法に関するものであり、特に、法面上に植生基盤を充填させるためのポケットを形成する工法に関するものである。
【0002】
【従来の技術】
従来より、法面に植生基盤を定着させて法面上に植生を図るための手段の1つとして法面上へ植生基盤を定着させるためのポケットを形成する手段が知られている。
【0003】
そして、例えば、特許第2852849号に提示されているように、平面状の網体に、水平方向に適宜間隔で支持材を取り付け、法肩から法尻に向けて吊り下げた吊り下げ材に、網体を弛ませた状態にして支持材を取り付けてポケットを形成するもの(図6参照)、実用新案登録第2556883号に提示されているように、落ち葉等の落下物が通過する大きさの網目の網体の背面に、植生基盤を留める補助網を、弛みを保たせて所定間隔で取り付けてポケットを形成するもの(図7参照)、特開平10−140577号公報に提示されているように、階段金網に組み込んだ枠部材に土留め材を挿入取り込んで植生を行うもので、巻回された形状、V字状のポケットを形成、通水性の不織布が組み込まれた土留め材を用いるものが知られている。
【0004】
ところが、特許第2852849号に提示されている工法は、支持材付きの網体および吊り下げ材は、それぞれロール状に巻回させて運搬することができるが、支持材および吊り下げ材に掛かる荷重が大きいため、これらには強度および剛性の大きな素材が必要であり、材料費が高価であった。加えて、支持材の強度および剛性が大きいことによって、凹凸の大きい法面では、法面の形状に合わせて施工することが困難であった。更に、吊り下げ材を法肩に強固に固定する必要があるため、法肩での工事ができない現場では、設置することができないという問題点を有していた。
【0005】
また、前記実用新案登録第2556883号に提示されている工法は、現場の法面上でポケットを形成するのは困難であり、通常は、予めポケットが形成された網体を現場に運搬して施工する方法が採られるが、この網体は極めてかさばるため、運搬しにくくかさばるため、運搬コストが高くついていた。更に、現場でポケットの位置や大きさを設計変更することができないため、法面の凹凸が大きい場合や勾配が一定でない場合には、ポケットが重なり合うことになり設置しにくかった。
【0006】
更に、特開平10−140577号公報に提示されている工法は、土留め材を予め或いは後工程で階段金網に取り付けたものであるため、1つ1つの階段に取り付けるのは困難で手間が掛かるという問題がある。
【0007】
【発明が解決しようとする課題】
本発明は、上記のような問題点を解決し、運搬が容易であるとともに、法面の形状に左右されずに容易に施工可能であり、且つ低コストな法面上における植生用ポケットの形成工法を提案するものである。
【0008】
【課題を解決するための手段】
そこで、本発明は、植物の根や茎の進入が可能であるとともに植生基盤材を保持することが可能な適宜の幅を有する土留めシートを、所定間隔毎に横方向へ折り曲げて複数の襞部を形成するとともに襞部の折曲部を上方側に向けた状態で前記土留めシートの平面部に弛みを保たせた状態で仮止めし且つ襞部の両端を閉じて、前記襞部と前記弛みを保たせた平面部とでポケットを形成したポケット材を、法面の法肩から法尻に向けて敷設した後、その上に、本木植物の生育に支障がなく落ち葉や種子が通過可能な大きさの網目を有する網体を張設して前記法面上に固定するとともに、前記ポケットを形成する襞部の頂部と前記網体とを緊結して前記ポケットの形状を保持させることとした。
【0009】
ポケットを形成するポケット材と網体とを別体とすることによって、運搬が容易であるとともに、ポケット材を法面の形状に合わせて敷設した後に網体を張設することができるので、どのような法面にも適用することができる。
【0010】
また、ポケット材の襞部の下端辺を縫製して環状にすると、環状部の内部へ断熱シートを挿入するだけで、容易に断熱工事を行うことができる。更に、環状襞部の上端に線材を挿入すれば、ポケットの形状を保持させるとともに、網体へ固定しやすくなる。
【0011】
更にまた、ポケット材の平面部の適宜位置に線材を取り付けて網体と線材とを緊結することにより、法面の形状等に応じて、植生基盤の形状や量を自在に調整することができる。
【0012】
【発明の実施の形態】
本発明の実施の形態を図面に基づいて説明する。
【0013】
図1乃至図3は本発明の好ましい実施の形態を示すものである。
【0014】
先ず、図1(A)に示すように、例えば細かい網目を有する網、ラッセル網や不織布等のように、伸長する植物の根や茎の進入が可能で、且つ客土や堆肥等の植生基盤材を保持可能な適宜の幅を有する土留めシート1を、所定間隔毎に横方向へ折り曲げて複数の襞部2を順次形成するとともに、各襞部2の上方側の内側面および襞内に断熱シート3を取り付け、更に、各襞部2における折曲部21の近傍に折曲部21に沿って横方向へ延びる線材4を配置、固定する。
【0015】
そして、例えば図1(B)に示すように、襞部2の折曲部21を上方側に向け状態で平面部22に弛みを保たせた状態で仮止めし且つ各襞部2の両端23,24を閉じて、各襞部2と弛みを保たせた平面部22との間隙にポケット5を形成したポケット材6を作成する。尚、前記仮止めは、例えば手で切断可能か或いはミシン目や切れ目等のように容易に切断可能とした手段を施した糸や帯等、或いは弱い結合力で接着させる等、現場で施工する際に、特殊な道具を使わなくても容易に仮止めを解除することができるものが好ましい。
【0016】
また、ポケット材6における、襞部2の幅や形成間隔は、施工する法面の傾斜や表面の状況、更には長さなどに応じて適宜変化させると効率が良く、複数種類を予め用意しておいたものから適宜選択するか、施工する法面に適したものを独自に作成する。
【0017】
このようにして製造されたポケット材6は、例えば巻回された状態、或いは適宜の長さに折り畳んだ状態で保管され、また、現場に運搬される。
【0018】
そして、図2(A)に示すように、最初に例えば巻回状のポケット材6の上端辺61を、例えばアンカ7などにより法面8の法肩81付近に固定して法尻方へと展開し、図2(B)に示すように、法面8上に敷設する。
【0019】
次に、図2(C)に示すように、前記法面8に敷設したポケット材6上の適宜間隔を有した位置に設置されるように、例えば金網等からなる網体9を張設し、アンカー10を用いて法面8上に固定する。更に、図2(D)に示すように、前記襞部2の仮止めを解除しながら各襞部2と弛みを保たせた平面部22との間隙ならびに閉じた両端部23,24とで所定形状のポケット5が形成されるように緊結位置を調節しながら線材4と網体9とを紐や接続金具等を用いて緊結する。こうして、法面8上に多数のポケット5が並設されるので、各ポケット5内に、図2(E)に示すように、植生基盤材11を充填する。
【0020】
尚、本実施の形態では、ポケット材6は襞部2の近傍に配設した線材4を介して配設されているので、ポケット材6と網体9とを少ない緊結部で強固に固定されるうえ、ポケット5の形状が安定するので施工作業が簡単迅速に行え、安定した状態でポケット5を形成することができる。
【0021】
また、本実施の形態では、襞部2における折曲部21の近傍に線材4を配設したが、図3に例示するように、襞部2の他の部分、或いはポケット材6の平面部22の任意の位置に設置してもよく、このようにすることにより、自在にポケットの形状を調整することができることから、法面8の凹凸が大きい場合や勾配が一定でない場合にも対応させることができるばかりか、ポケット5の大きさを自由に調整することができることから法面の状況や使用目的にあわせて植生基盤材の量を調整できることも可能で、経済的にも優れている。
【0022】
更に、本実施の形態では、線材4をポケット部材6の予め定めた位置に配設したが、現場における施工時に法面の凹凸や勾配等に応じてポケットの位置や大きさを調整しながら所望位置に取り付けても良く、更に、きめ細かい作業を簡単に行うことができる。
【0023】
更に、前記ポケット材6の上方に張設される網体9には、各ポケット5内に植栽した植物が伸長した際、植物の生育に支障がなく落ち葉や種子等の落下物を通過させて植生基盤11内に取り込めるように、落下物が通過可能な大きさの網目を有するものが用いらる。
【0024】
図4は本発明の異なる実施の形態を示すものであり、ポケット材6の襞部2の基端辺を縫製して、襞部2を環状に形成するものである。そのため、環状の襞部2の内部へ断熱シート3を挿入するだけで固定することなしに且つ施工時にも位置ずれや外れる心配がなく、容易に断熱工事を行うことができる。更に、環状の襞部2の上端に線材4を挿入すれば、ポケット5の形状を保持させるとともに、網体9へ固定しやすくなる。
【0025】
更に、図5は本発明を法枠81内に施工する場合の実施の形態を示すものであり、ポケット材6を法面8の奥行きに応じて設置し網体9を固定することができるので法面8の奥行きに応じた設置が可能である。また、ポケット材6を適宜寸法で作成することによって、法枠81の大きさや深さに応じて自在にポケット5を形成することが可能である。
【0026】
【発明の効果】
本発明によると、ポケットを形成するポケット材と網体とが別体になっているので、保管ならびに運搬時にかさばることがなく、運搬コストを低くおさえることができる。
【0027】
しかも、ポケット材の製造や現場での取り付けに関して特殊な技術や道具等を必要とせず、誰にでも容易に実施することができ、ポケット材と網体とが別体になっているので横方向に広がっている法面に対しても対処しやすい。
【0028】
また、網体の設置高さやポケット体と網体との固定位置等を調整することによって、ポケットの大きさや網体の目などを法面の凹凸や勾配の変化等、現場の状況に容易に適応することができる。
【0029】
更に、ポケット材に線材を取り付けて網体と線材とを緊結することにより少ない緊結個所で強固に固定されるので施工作業が簡単且つ短時間で済むだけでなく、ポケットの形状も安定しやすい。
【0030】
更にまた、法枠内に施工する場合に、ポケット材を法面の奥行きに応じて設置し網体を固定することができるので法面の奥行きに応じた設置が可能である。また、ポケット材を適宜寸法で作成することによって、法枠の大きさや深さに応じて自在にポケットを形成することも可能である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for fixing a vegetation base on a slope and achieving vegetation on the slope, and more particularly to a method for forming a pocket for filling a vegetation base on the slope. .
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a means for forming a pocket for fixing a vegetation base on a slope has been known as one of means for fixing a vegetation base on the slope and achieving vegetation on the slope.
[0003]
Then, for example, as disclosed in Japanese Patent No. 2852849, a support member is attached to a flat net at appropriate intervals in the horizontal direction, and a suspending member suspended from the shoulder to the hip is used. A pocket is formed by attaching a supporting member with the net body slackened (see FIG. 6). As shown in Japanese Utility Model Registration No. 25555683, a pocket having a size through which a falling object such as a fallen leaf passes. An auxiliary net for holding a vegetation base is attached to the back of the mesh net at predetermined intervals while keeping slack (see FIG. 7), as disclosed in JP-A-10-140577. The vegetation is carried out by inserting the earth retaining material into the frame member incorporated in the staircase wire netting, forming a wound shape, forming a V-shaped pocket, and using an earth retaining material incorporating a water-permeable nonwoven fabric. Things are known .
[0004]
However, according to the construction method disclosed in Japanese Patent No. 2852849, the mesh body with the supporting material and the hanging material can be transported by being wound in a roll shape, respectively, but the load applied to the supporting material and the hanging material can be transported. Therefore, these materials require high strength and rigidity, and the material cost is high. In addition, due to the strength and rigidity of the support material, it is difficult to construct a slope having large irregularities according to the shape of the slope. Furthermore, since it is necessary to firmly fix the hanging material to the shoulder, there is a problem that it cannot be installed at a site where construction at the shoulder is not possible.
[0005]
Further, it is difficult to form a pocket on the slope of the site by the construction method disclosed in the Utility Model Registration No. 25555683, and usually, a net having a pocket formed in advance is transported to the site to transport the net to the site. Although the method of construction is adopted, this net body is extremely bulky, difficult to transport, and bulky, so that the transportation cost is high. Furthermore, since the position and size of the pockets cannot be changed at the site, the pockets overlap when the unevenness of the slope is large or the slope is not constant.
[0006]
Further, in the construction method disclosed in Japanese Patent Application Laid-Open No. H10-140577, since the earth retaining material is attached to a staircase wire mesh in advance or in a later process, it is difficult and time-consuming to attach the retaining material to each step. There is a problem.
[0007]
[Problems to be solved by the invention]
The present invention solves the problems described above, is easy to carry, can be easily constructed irrespective of the shape of the slope, and forms pockets for vegetation on the slope at low cost. It proposes a construction method.
[0008]
[Means for Solving the Problems]
Accordingly, the present invention provides a plurality of folds by bending a retaining sheet having an appropriate width capable of entering the roots and stems of a plant and holding a vegetation base material at predetermined intervals in a lateral direction. With the bent portion of the fold portion facing upward, the portion is temporarily fixed while keeping the flat portion of the retaining sheet loose, and both ends of the fold portion are closed. After laying a pocket material that forms a pocket with the flat part that keeps the slack, from the slope of the slope to the bottom of the slope, on it, fallen leaves and seeds do not hinder the growth of the main tree plant A net having a mesh of a size that can pass therethrough is stretched and fixed on the slope, and the top of the fold forming the pocket and the net are tightly held to maintain the shape of the pocket. I decided.
[0009]
By separately forming the pocket material and the net forming the pocket, it is easy to carry, and the net can be stretched after the pocket material is laid according to the shape of the slope. It can be applied to such slopes.
[0010]
Further, when the lower end side of the fold portion of the pocket material is sewn to form an annular shape, heat insulating work can be easily performed simply by inserting an insulating sheet into the annular portion. Furthermore, if a wire is inserted into the upper end of the annular fold, the shape of the pocket can be maintained and it can be easily fixed to the net.
[0011]
Furthermore, the shape and amount of the vegetation base can be freely adjusted according to the shape of the slope by attaching the wire at an appropriate position on the plane portion of the pocket material and tightening the net and the wire. .
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
[0013]

[0014]
First, as shown in FIG. 1 (A), the roots and stems of elongating plants can enter, such as a net having a fine mesh, a Russell net or a nonwoven fabric, and a vegetation base such as soil or compost. An earth retaining sheet 1 having an appropriate width capable of holding the material is folded laterally at predetermined intervals to form a plurality of folds 2 sequentially, and the inner side surface and the folds on the upper side of each fold 2 are formed. The heat insulating sheet 3 is attached, and the wire 4 extending in the lateral direction along the bent portion 21 is arranged and fixed near the bent portion 21 in each fold portion 2.
[0015]
Then, as shown in FIG. 1B, for example, the bent portion 21 of the fold portion 2 is temporarily fixed in a state where the flat portion 22 is kept loose with the bent portion 21 facing upward, and both ends 23 of each fold portion 2 , 24 are closed to form a pocket material 6 in which a pocket 5 is formed in a gap between each fold portion 2 and a flat portion 22 having slack. In addition, the temporary fixing is performed on site, for example, by using a thread or a band that can be cut by hand or a means that can be easily cut such as a perforation or a cut, or by bonding with a weak bonding force. In this case, it is preferable that the temporary fixing can be easily released without using a special tool.
[0016]
In addition, if the width and the forming interval of the fold portion 2 in the pocket material 6 are appropriately changed according to the slope of the slope to be constructed, the surface condition, and the length, etc., it is efficient to prepare a plurality of types in advance. Select the appropriate one from the presets or create your own suitable for the slope to be constructed.
[0017]
The pocket material 6 thus manufactured is stored, for example, in a wound state or in a state of being folded to an appropriate length, and is transported to the site.
[0018]
Then, as shown in FIG. 2 (A), first, for example, the upper end side 61 of the wound pocket material 6 is fixed to the vicinity of the slope 81 of the slope 8 by, for example, the anchor 7 and the like, and is shifted toward the slope. It is developed and laid on the slope 8 as shown in FIG.
[0019]
Next, as shown in FIG. 2C, a mesh body 9 made of, for example, a wire mesh is stretched so as to be installed at a position having an appropriate interval on the pocket material 6 laid on the slope 8. Is fixed on the slope 8 using the anchor 10. Further, as shown in FIG. 2 (D), while the temporary fixing of the folds 2 is released, the gap between each fold 2 and the flattened portion 22 and the closed both ends 23, 24 are determined by the gap. The wire 4 and the net 9 are tied together using a string or a connection fitting while adjusting the tying position so that the pocket 5 having the shape is formed. In this way, a large number of pockets 5 are juxtaposed on the slope 8, and each pocket 5 is filled with the vegetation base material 11 as shown in FIG.
[0020]
In the present embodiment, since the pocket material 6 is provided via the wire 4 provided in the vicinity of the fold portion 2, the pocket material 6 and the net 9 are firmly fixed with a small number of binding portions. In addition, since the shape of the pocket 5 is stabilized, the construction work can be performed easily and quickly, and the pocket 5 can be formed in a stable state.
[0021]
Further, in the present embodiment, the wire 4 is disposed in the vicinity of the bent portion 21 in the fold 2, but as illustrated in FIG. 22 may be installed at any position. By doing so, the shape of the pocket can be adjusted freely, so that it is possible to cope with the case where the unevenness of the slope 8 is large or the slope is not constant. In addition to being able to adjust the size of the pocket 5, the size of the vegetation base material can be adjusted according to the conditions of the slope and the purpose of use because the size of the pocket 5 can be freely adjusted, which is economically excellent.
[0022]
Further, in the present embodiment, the wire 4 is disposed at a predetermined position of the pocket member 6, but it is possible to adjust the position and size of the pocket in accordance with unevenness or slope of the slope at the time of construction at the site. It may be attached to a position, and further, detailed work can be easily performed.
[0023]
Furthermore, when the plants planted in each pocket 5 elongate, the fallen objects such as fallen leaves and seeds pass through the mesh body 9 stretched above the pocket material 6 without any hindrance to the growth of the plants. What has the mesh of the magnitude | size which a fallen object can pass so that it can be taken in the vegetation base 11 by using is used.
[0024]
FIG. 4 shows a different embodiment of the present invention, in which the base end of the fold 2 of the pocket material 6 is sewn to form the fold 2 in an annular shape. Therefore, it is possible to easily perform the heat insulation work without inserting and fixing the heat insulation sheet 3 into the inside of the annular fold portion 2 without having to worry about displacement or detachment at the time of construction. Furthermore, if the wire 4 is inserted into the upper end of the annular fold 2, the shape of the pocket 5 can be maintained and the pocket 5 can be easily fixed to the net 9.
[0025]
FIG. 5 shows an embodiment in which the present invention is applied to the inside of the lawn frame 81. Since the pocket material 6 can be installed according to the depth of the slope 8 and the net body 9 can be fixed. Installation according to the depth of the slope 8 is possible. In addition, by appropriately forming the pocket material 6, it is possible to freely form the pocket 5 according to the size and depth of the legal frame 81.
[0026]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, since the pocket material which forms a pocket and the net are separate bodies, it is not bulky at the time of storage and transportation, and can hold down transportation cost.
[0027]
Moreover, no special skills or tools are required for the manufacture of the pocket material or installation at the site, so it can be easily carried out by anyone, and since the pocket material and the net are separate, It is easy to deal with slopes that are widespread.
[0028]
In addition, by adjusting the installation height of the mesh body and the fixing position of the pocket body and the mesh body, the size of the pocket and the eyes of the mesh body can be easily adjusted to the situation of the site such as unevenness of the slope and changes in the slope. Can be adapted.
[0029]
Further, since the wire is attached to the pocket material and the net body and the wire are tightened, they are firmly fixed at a small number of tying points, so that not only the construction work can be completed easily and in a short time, but also the shape of the pocket is easily stabilized.
[0030]
Furthermore, when the work is carried out in the slope, the pocket material can be installed according to the depth of the slope and the net can be fixed, so that the installation according to the depth of the slope is possible.
