次に、２枚の内枠■′を組み合せて、内枠■を形成する
。Next, the two inner frames ■' are combined to form an inner frame ■.
外枠■の内側に、おのおのＬ字形に折り曲げられた内枠
材■′の曲折部を突き合わせ相互にＬ字状の折曲げ部の
内側に挿入し内枠材■’Ｍ文字の形に配置する。The bent parts of the inner frame material ■', each bent in an L-shape, are butted against the inside of the outer frame ■, and each is inserted inside the L-shaped bent parts, and the inner frame material ■' is arranged in the shape of the letter M. .
２枚の内枠材■ｌを突き合わせてできる、共有する空間
２１の径は枠材を法面へ固定する際に使用するメインア
ンカー■の径とほぼ同径か、多少の隙間を有するように
配置する。The diameter of the shared space 21 created by butting the two inner frame materials ■l together should be approximately the same diameter as the diameter of the main anchor ■ used when fixing the frame materials to the slope, or have a slight gap. Deploy.
外枠■と内枠■の接する４点に、それぞれ内枠連結具■
を介在させ、ピン■を挿入し、内枠■を固定する。Attach inner frame connectors to each of the four points where the outer frame and inner frame meet.
, insert the pin ■, and fix the inner frame ■.
固定方法は、外枠■の連結方法と同様に、内枠■の金網
と外枠■の金網との目の間に、はぼ直角に折り曲げられ
た基板４１の突設されたピン受は部４２を組み込み突設

〈２〉法面への枠材配置、固定
前記の工程で組み立てられた枠材を多数個、法面へおの
おの隣接するように配置する。<2> Arranging and fixing the frame members on the slope A large number of frame members assembled in the above steps are arranged adjacent to each other on the slope.
枠材配置の形態は、法面保護の必要な範囲に応じて、ま
す目状、又は、千鳥状に配置する。The frame materials are arranged in a grid pattern or a staggered pattern, depending on the required range of slope protection.
このような配置は、各枠材の相互間に連続した作用をは
たらかせるためである。This arrangement is intended to allow each frame member to work continuously with each other.
次に、それぞれＱ外枠■の隣接する箇所の法面に鋼棒の
一端にフックを形成したサブアンカー■を打ち込む。Next, sub-anchors (2) each having a hook formed at one end of a steel rod are driven into the slope at adjacent locations of the Q outer frame (2).
サブアンカー■は、外枠■に内接する箇所で、かつサブ
アンカー■のフック部が、当該外枠■と外接する他の外
枠■をも同時に固定できる箇所に打ち込む。The sub-anchor (2) is driven into a location that is inscribed in the outer frame (2) and at a location where the hook portion of the sub-anchor (2) can simultaneously fix another outer frame (2) that is circumscribed with the outer frame (2).
サブアンカー■による外枠の固定と並行して、またはそ
の前後に、′内枠■を固定する目的の、メインアンカー
■を２枚の内枠材■′を交叉してできる余聞２１を貫通
させて、法面へ打ち込み、内枠■を固定する。In parallel with, or before and after fixing the outer frame with the sub-anchor ■, the main anchor ■ is passed through the gap 21 created by intersecting the two inner frame materials ■ for the purpose of fixing the inner frame ■. Then, drive it into the slope and fix the inner frame ■.
なお場合によってはメインアンカー８を空間２１の外に
打ち込み、フック部分を余聞２１に貫通させる方法も可
能である。In some cases, it is also possible to drive the main anchor 8 outside the space 21 and allow the hook portion to penetrate the hole 21.
メインアンカー■は、サブアンカー■同様に、強度に優
れた鋼棒で同形状のものであり、枠材固定の範囲に合っ
た適度の長さを有するものとし、アンカーの全長と、フ
ック部の長さの関係も同様とする。The main anchor ■, like the sub-anchor ■, is a steel rod with excellent strength and the same shape, and has an appropriate length that matches the range of fixing the frame material, and the overall length of the anchor and the hook part The same holds true for the length relationship.
また、外枠■を補強する目的の内枠■の内枠材■′の枚
数は、保護する法面の状態に適応する範囲であれば２枚
以上使用することも可能である。Further, the number of inner frame members ■' of the inner frame ■ for the purpose of reinforcing the outer frame ■ may be two or more as long as it is within the range that is compatible with the condition of the slope to be protected.
このようにして、全ての外枠■の接点に、サブアンカー
■を打ち固定し、内枠■の交叉する箇所には、メインア
ンカー■を打ち固定することは、枠材の構造、及び枠材
の配置の関係からも、それぞれ独立した効能（固定）に
止どまらず、相互間に連結した統合的な効能（固定、及
び補強）をも意味する。In this way, the sub-anchors ■ are fixed at the contact points of all the outer frames ■, and the main anchors ■ are fixed at the points where the inner frames ■ intersect. Due to the arrangement of the two, it means not only independent effects (fixation) but also integrated effects (fixation and reinforcement) that are connected to each other.
特にメインアンカー８は、複数の内枠材２のＬ字状折り
曲げ部を交互に綴り合わせるような状態で相互に挿入し
て形成した空間２１を貫通する。In particular, the main anchor 8 penetrates a space 21 formed by inserting the L-shaped bent portions of a plurality of inner frame members 2 into each other in a state in which they are alternately stitched together.
その結果り字状の内枠材２′は強固に十文字状に拘束さ
れ、円弧状の外枠１と一体となって外１を内側から確実
に補強する。As a result, the cross-shaped inner frame member 2' is firmly restrained in a cross shape, and is integrated with the arc-shaped outer frame 1 to reliably reinforce the outer frame 1 from the inside.
また同時に外枠１と一体の内枠２を法面に固定するので
内枠２と一体の外枠１を確実に法面に固着する作用をは
たす。At the same time, since the inner frame 2, which is integral with the outer frame 1, is fixed to the slope, the outer frame 1, which is integral with the inner frame 2, is reliably fixed to the slope.
このようにメインアンカー８は内枠２と外枠１を一体化
すると共に、サブアンカー９と同様に保護材全体を法面
に固定することになる。In this way, the main anchor 8 integrates the inner frame 2 and the outer frame 1, and, like the sub-anchor 9, fixes the entire protective material to the slope.
従って一部の法面に崩壊があっても、最小限度にくい止
めることが可能である。Therefore, even if a part of the slope collapses, it can be stopped to a minimum.
特に、水による法面上砂の流出、崩壊を防止するために
は、枠材の網目の大きさを適当に選択することによって
防止することが可能である。In particular, in order to prevent the sand from flowing out and collapsing on the slope due to water, it is possible to prevent this by appropriately selecting the mesh size of the frame material.
〈３〉客土、植生 枠材社に枠材がかくれる程度に客土を行ない植生する。<3> Soil, vegetation Add soil to the frame material and add vegetation to the extent that it will cover the frame material.
枠材く金網によって、構成されているので、容易に土中
に埋設させることができる。Since the frame is made of wire mesh, it can be easily buried in the ground.
また、枠材が金網によって構成されているので、排水性
にも優れ、土中に染み込んだ雨水などが、枠材の網目を
通り抜け、崩壊の原因ともなる、水留りが生じにくい。In addition, since the frame material is made of wire mesh, it has excellent drainage, and rainwater that has seeped into the soil passes through the mesh of the frame material, making it difficult for water to accumulate, which can cause collapse.
枠材が、すっぽりと、土中に埋設可能なため、法面の全
面緑化ができる。The frame material can be completely buried in the soil, making it possible to fully green the slope.
その上、植生した植物の根が枠材にからみつき易く、簡
単に緑化ができ、枠材自体の補強が可能である。In addition, the roots of the growing plants tend to get entangled with the frame material, making greening easy and reinforcing the frame material itself.
本発明は、以上のような構成から、次のような効果を得
ることができる。The present invention can obtain the following effects from the above configuration.
〈１〉第３図に示すように単純な形状の枠材に分割され
ているため、格納や運搬に大変便利であり、かつ組立て
作業の省力化がはかれる。<1> As shown in Fig. 3, since it is divided into simple-shaped frame members, it is very convenient to store and transport, and labor-saving assembly work can be achieved.
〈２〉柔軟性を有する枠材を使用するため、凹凸の法面
にも容易に適応し、施行が簡単である。<2> Since a flexible frame material is used, it can be easily adapted to uneven slopes and is easy to install.
〈３〉排水性に優れた枠材を使用するため、水による法
面崩壊が防止できる。<3> Since a frame material with excellent drainage properties is used, slope collapse due to water can be prevented.
〈４〉枠材自体を地中に埋設するため、より一層の美化
がはかれる。<4> Since the frame material itself is buried underground, further beautification can be achieved.
〈５〉芝などの植物のねからみが容易で、全面緑化がで
きる。<5> It is easy to grow plants such as grass, and the entire area can be greened.
〈６〉外枠の外に内枠も使用するため、客土の安定性が
向上する。<6> Since the inner frame is also used in addition to the outer frame, the stability of the soil is improved.
〈７〉枠材の構造、及び枠材の配置から、枠材の連結力
が相互間に使用し合い、法面土砂の流出、崩壊を最小限
度に（い止めることができる。<7> Due to the structure of the frame materials and the arrangement of the frame materials, the connecting force of the frame materials is mutually used, and the outflow and collapse of slope earth and sand can be minimized (prevented).
