NONWOVEN FABRIC, AND EROSION PREVENTION MATERIAL USING THE SAME AND EROSION PREVENTION METHOD
PROBLEM TO BE SOLVED: To provide a nonwoven fabric and an erosion prevention material which can protect a slope and are suitable for being used when drilling work is performed upon being installed on the slope, and to provide an erosion prevention method.SOLUTION: A nonwoven fabric 2 has basis weight of 25 to 155 g/m, the ratio of component fiber in the basis weight is equal to or larger than 50%. The average fineness of the component fiber is 2 to 100 dtex. Partial junction between gauze 1 and the nonwoven fabric 2 at a plurality of joint regions 3 configures an erosion prevention material E, in jointing the nonwoven fabric 2 to one side of the gauze 1. Using the erosion prevention material E in such a way that the nonwoven fabric 2 is located on the lower side thereof prevents erosion of a slope N.
【課題】法面の保護を図ることができ、特に法面への設置の際にドリリング作業が行われる場合に用いて好適な不織布並びに侵食防止材及び侵食防止方法を提供すること。【解決手段】不織布２の目付けを２５〜１５５ｇ／ｍ２とし、目付けにおける構成繊維の比率を５０％以上とし、前記構成繊維の平均繊度を２〜１００ｄｔｅｘとする。また、不織布２を金網１の片側に接合するに際して、金網１と不織布２とを複数の接合領域３において部分的に接合することにより、侵食防止材Ｅを構成する。さらに、不織布２が下側となるように侵食防止材Ｅを用いて法面Ｎの侵食防止を図る。【選択図】図１
