3、.1.Scope1.1 This guide covers procedures that can be employed tomechanically attach fabricated geomembranes to structures,pipes,etc.1.2 This guide does not address all problems or situations ageomembrane installer or design engineer may face in theattachment of geomembranes to structures,pipes,etc.T
4、he solepurpose of this standard guide is to point out typical problemswith geomembrane attachments and clearly state objectives ofeach component of the geomembrane attachment(s).1.3 This guide has been generated for geomembrane appli-cation(s);however,a geomembrane installer or designengineer,or bot
5、h,may find portions of this guide applicable toother geosynthetics.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.Combinin
6、gvalues from the two systems may result in non-conformancewith the standard.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine
