【発明の詳細な説明】
本発明は、法面の土砂の崩落と、吹付基本の崩
落を防止する為に考えられた網体及び工法の発明
に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a net structure and construction method designed to prevent the collapse of earth and sand on slopes and the collapse of spraying bases.
（従来技術）
従来より法面の土砂の崩落を防止する方法とし
て、網体を法面に張設する方法が広く実施され、
それなりの効果を上げている。(Prior art) As a conventional method for preventing the collapse of earth and sand on slopes, the method of stretching nets on slopes has been widely practiced.
It's having some effect.
又、法面における緑化工法として、種子吹付工
法が大量に採用されているが、種子吹付基材の崩
落防止という点では、勾配のゆるやかな盛土法面
を除き、特に切り取り法面では種子吹付基材の定
着率を増す為に網体を張設することが非常に有効
であり、全んどの切り取り法面で網体を併用した
種子吹付工法が行なわれている。 In addition, the seed spraying method is widely used as a greening method on slopes, but in terms of preventing the seed spray base material from collapsing, it is difficult to prevent the seed spray base material from collapsing, except for embankment slopes with gentle slopes, especially on cut-out slopes. It is very effective to install a net to increase the retention rate of the timber, and the seed spraying method is used in conjunction with the net on all cut slopes.

網体にあつては、張設時にアンカー、釘等の碇止
具で碇止させる場合、碇止部が破れたり、網体と
碇止具がはずれ易かつたりして、法面と網体との
唯一の接点である碇止部が一体とならず、これが
問題となつていた。 Even with the nets that are used in large quantities, especially those woven from chemical or vegetable fibers, they must be anchored with anchors, nails, or other anchoring devices when being stretched. If this happens, the anchoring part may be torn, or the net and anchoring device may easily come off, causing the anchoring part, which is the only point of contact between the slope and the netting, to not become one piece, which is a problem. Ta.
この法面と網体が一体とならないということは
網体が法面土砂の崩落防止効果に乏しいと同時

亡しやすいということであり、この点の改良が望
まれていたのである。 The fact that the slope and the net are not integrated means that the net has a poor effect on preventing slope soil from collapsing, and at the same time, when the seed spraying method is used, the seed spraying base material is likely to be washed away. Improvements were desired.
本発明者等は、この従来の網体の欠点に鑑み、
種々研究を重ねた結果、碇止具でもつて網体を法

たせればよいという知見に基き、本発明に到達し
た。 In view of the drawbacks of this conventional mesh, the present inventors
As a result of various studies, we have arrived at the present invention based on the knowledge that if the anchoring device has a part that anchors the net on the slope, it is sufficient to make it wider and stronger.
以下本発明の構成を説明する。 The configuration of the present invention will be explained below.
（本発明の構成）
本発明の網体の内テープ部を除く部分を構成す

ラあるいはフラツトヤーンと呼ばれる糸が最も使
用に適している。(Structure of the present invention) The material constituting the portion of the mesh body of the present invention other than the inner tape portion may be made of chemical, vegetable, or metallic material, and may be monofilament or flat yarn, which is a chemical fiber thread. The most suitable thread is called .
又、この網体を編織する際用いるテープは、ポ
リエチレン、ポリプロピレン等の材質で巾が５〜
25mmのものを用いる。 Also, the tape used when weaving this net is made of polyethylene, polypropylene, etc. and has a width of 5 to 50 mm.
Use a 25mm one.
以上の材料を用いて本発明の網体を構成するに
はモノヒラあるいはフラツトヤーン糸を用いてラ
ツセル編みという編み方にて網体を編んでゆき、
通常横方向適宜間隔毎にテープを編み込むように
して完成する。 In order to construct the net of the present invention using the above-mentioned materials, the net is knitted using a monofila or flat yarn using a latssel stitch method.
It is usually completed by weaving tapes at appropriate intervals in the lateral direction.
テープを編み込むピツチは通常20〜50cm間隔で
任意に選択し、網体の巾は1.5〜２ｍ、長さは、
100ｍで両端部と中央部に補助ロープを配置する
ようにし、荷姿はロール巻きとする。 The pitches in which the tape is woven are usually arbitrarily selected at intervals of 20 to 50 cm, the width of the net is 1.5 to 2 m, and the length is:
Auxiliary ropes will be placed at both ends and in the center for a length of 100m, and the packaging will be rolled.
この網体を広げてみれば、横縞模様を呈するの
である。 When this net is expanded, it appears as a horizontal striped pattern.
以上のようにして製造した網体を法面に搬入し
施工する施工方法につき説明すると、法面上部か

面に完全に密着するよう張設し、網体と法面を強
固に一体化させるようにするのである。網体を法
面に張設したならば、通常公知の種子吹付工法を
行う。 To explain the construction method in which the net produced as described above is carried onto the slope and installed, the net is placed from the top of the slope so as to form a horizontal striped pattern on the slope.
By driving anchor fasteners into the tape section, the net is stretched so as to be in complete contact with the slope, and the net and the slope are firmly integrated. Once the net is stretched on the slope, a commonly known seed spraying method is carried out.

止用網体及び該網体を使用した土砂崩落防止工法
であるから、網体は法面と強固に一体となること
ができる。(Effects of the present invention) As described above, the present invention provides a net for preventing landslides, which is formed by weaving tapes at appropriate intervals at least in the lateral direction of the net, and a construction method for preventing landslides using the net. Because of this, the net body can be firmly integrated with the slope.
従つて通常の網体のように碇止具によつて破れ
るとか、はずれるといつたようなことはなくな
り、法面の土砂の崩壊を網体のテープ部で完全に
遮断して防止できたのである。 Therefore, unlike regular nets, there is no chance of the net being torn by the anchorage or coming off, and the tape section of the net can completely block and prevent the collapse of earth and sand on the slope. be.
又、吹付を行なつたならば、吹付基材は網体の

生物は旺盛な生育をとげることができるのであ
る。 Moreover, when spraying is carried out, the sprayed base material stays on the tape part of the mesh body, and this becomes a base for vegetation, allowing plants to grow vigorously.
