| Abstract: | The current standards of prefabricated drain filters and present condition of short fiber filter in China are described in this paper, and it is pointed out lacking of two important indexes of the trapezoidal tearing strength and gluing strength of glued seam about the filter in the standard. The superiority of the long fiber filter are explained,the difference between the domestic long fiber filter and imported one is presented,and it can draw that the import one can be replaced by domestic one completely at present.The suggestion standards of the filter technique indexes are put forward to provide a reference for revising standard. |
| Keywords: | prefabricated vertical drain filter made of short fiber filter made of long fiber trapezoidal tearing strength standard for filter of PVD |
