1、Designation:D646219Standard Practice forSilt Fence Installation and Maintenance1This standard is issued under the fixed designation D6462;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parenthes
2、es indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers common installation and mainte-nance procedures for temporary silt fence applications.Thispractice is based on AASHTO M288.1.2 This pract
3、ice is applicable to the use of silt fence as avertical permeable interceptor designed to remove suspendedsoil from overland,non-concentrated water flow.The functionof a temporary silt fence is to trap and allow settlement of soilparticles from sediment laden water by intercepting andimpounding wate
4、r in an effort to slow the transport velocityand provide storage for sediment to be captured.The purposeis to greatly limit the transport of eroded soil from theconstruction site by water runoff.1.3 The practices presented herein are intended to ensuregood workmanship and quality,but do not necessar
5、ily apply tothe concentrated flow applications.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents,therefore eachsystem shall be used independently of the other.Combiningvalues from the two
