An Evaluation of the Applicability and Cost of Polyester Resin and Cementitious Grouts for the Installation of Rock Anchors at Hydro Projects

Document Type: Proceeding Paper

Part of: Waterpower '89

Abstract:

The success of two proposed hydropower projects in the States of Virginia, and West Virginia depended on the ability of a rock anchor system to support the penstocks at the crown of the tunnel. Both projects involved dams built by the U.S. Army Corps of Engineers. The rock anchor system heavily relies on the bond between the anchor and the supporting rock mass. This bond is provided by the bonding agent that fills the clearance between the anchor bolt and the rock mass. Polyester resin and cemtitious grouts are the most common bonding agents used in rock anchor installations. The purpose of this paper is to report the results of a study on the merits and demerits of polyester resin grouted anchor system and cement grouted anchor system as viable alternatives for use in these projects.
