Title:
EROSION CONTROL SHEET MAT CAPABLE OF BEING LAID/REMOVED AND CAPABLE OF GREENING
Document Type and Number:
Japanese Patent JP3396199
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an erosion control sheet mat capable of being laid/removed and capable of greening, which protect a bank slope surface and the like from erosion while performing greening of the same, are excellent in strength, flexibility, and durability, do not mount laying costs, does not pose a danger of washed- away of plants after laying of the sheet mat, and forms a slope surface beautiful to the eye.
SOLUTION: The erosion control sheet mat capable of being laid/removed and capable of greening, are comprised of a thermoplastic resin fibrous material, a net-like material, a tape-like material, or a composite material of the same, each fiber having a diameter of 0.1 to 5 mm, and formed into a three- dimensional porous sheet mat having a porosity (λp) of 80% or more. The thickness of the sheet mat is set to a value (mm) or less calculated by the following equation: [20d/{1-(λp/100)}0.5], and at the same time set to 50 mm or less.
