Specification :

Hook case Penn nets overall growth square, using the latest environmental protection structure of technical, mainly for river, bank slope, roadbed protection structure. Can prevent the Banks, waves of erosion by water. During construction, cage, constitute structure filling stone flexible, permeability is strong integrity materials and promote the rapid growth of natural plants. In river regulation engineering, traditional river revetment or revetment generally USES the plasma QiShi or concrete, three area light, impervious, already cannot adapt to the needs of the natural ecological controlling, and hook case Penn nets anti-scouring dint strong, strong permeability and porosity of biological easy to inhabit tectonic, so more often used to many ZiRanXing ecological rivers construction.
