Standard Practice for Specifying Rock to Fill Gabions, Revet Mattresses, and Gabion Mattresses — 3 стр.
Значение и использование

5.1 Gabions and mattresses are described in Specifications A974 and A975. Gabions and mattresses are primarily used for earth retaining walls, erosion mitigation and scour protection works. Their ability to function properly depends on their stability, which is partly dependent upon the rocks filling them. Rock sizes should be chosen to prevent individual rocks from falling through the mesh of the gabions or mattresses. The rock also has to withstand natural weathering processes during the life of the project that would cause it to breakdown to sizes smaller than the wire mesh opening dimensions.

Область применения

1.1 This practice covers the sizes and quality of rock to fill gabions and mattresses.

1.2 This practice does not cover the sizes and quality of rock for other erosion control uses such as riprap or drainage.

1.3 This practice does not cover the material properties or construction of gabions or mattresses.

1.4 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
