Abstract:
Rock anchors, inflation chucks, and inflation systems such as those described herein, allow for substantially complete draining of fluids from interior volumes of the rock anchors. In various situations, corrosive fluids may be introduced to the rock anchor, including inflating the rock anchors and during normal use, such as by groundwater intrusion. The inflation chucks described herein include multiple inflation paths for more effectively introducing and draining fluid from rock anchors during inflation processes and during general use.

Claim (Index 1):
A method for expanding and draining an expandable rock anchor comprising:\n inserting, at least partially into a borehole, a rock anchor having a first shape having a first diameter that is less than a diameter of the borehole, the rock anchor defining first and second openings to an interior volume of the rock anchor; coupling an inflation system to the interior volume of the rock anchor using an inflation chuck; introducing, using the inflation system, a first fluid into the interior volume, thereby causing the rock anchor to expand to a second shape having a second diameter that is greater than the first diameter and substantially equal to the diameter of the borehole; introducing, by the inflation system, a second fluid into the interior volume, thereby displacing the first fluid and draining substantially all of the first fluid from the interior volume via at least one of the first or second openings, wherein:\n the rock anchor maintains the second shape following the draining of substantially all of the first fluid from the interior volume; and \n an exterior surface of the expanded rock anchor engages with an interior surface of the borehole, thereby retaining the rock anchor in the borehole.
