| 摘要： | Nearly all geomembrane installations are fixed at the perimeter of the containment by burying the liner in an anchor trench or by attaching it to concrete (i.e., a collar wall, foundation, ring wall, manhole, vault, etc.). The standard approach for connecting the geomembrane liner to concrete is to use anchor bolt geomembrane connections with batten strip or Rondel connections, as described in ASTM D6497, "Standard Guide for Mechanical Attachment of Geomembranes to Penetrations or Structures." For polyolefin (PE and PP) geomembranes, Rondels or embedment strips are the preferred methods of attachment for the following reasons. 1. Speed of installation: Welding to an embedment strip can reduce the time it takes to attach a liner to concrete. 2. Cost reduction: Stainless steel batten and anchors are expensive and labor intensive to install and maintain. |
