Description
図3は保護マット10の断面構造を示したものである。
固化処理土袋マット11に使用する織布としては加工糸を使用することが好ましく、例えば東洋紡績(株)製の土木工事用キャンバス#1030や#1050を使用することができる。
図4に示す試験装置20を用い、防滑性試験を下記手順により行った。
(1) 高摩擦不織布:850g/m2の長繊維不織布の表面に防滑処理*を施したもの。
(2) 高摩擦織布タイプ1:300kgf/3cm以上の織布の構成糸自体に高摩擦糸を編入することによって摩擦特性を向上させたもの。
(3) 高摩擦織布タイプ2:300kgf/3cm以上の織布表面に防滑処理*を施したもの。
(4) 高摩擦織布タイプ3:500kgf/3cm以上の織布表面に防滑処理*を施したもの。
(5) 一般の不織布
(6) 一般の織布
*アクリル樹脂および砂粒を対象物の表面に付着させ、表面をサンドペーパー状に加工したもの。
