Abstract
A method of making and applying a chemical anchoring adhesive in the form of a highly viscous, self-contained rope or slug is provided. The rope or slug has an average cross-sectional area determined from a formula that takes into account the cross-sectional area of a borehole, the average cross-sectional area of an anchor pin to be inserted into the borehole, and a penetration factor which reflects penetration of the adhesive into the walls of the borehole. By selecting the proper area for the anchoring adhesive, the rope can be cut into slugs having depths equal to the depths of boreholes. When the slugs are inserted into the boreholes, and anchor pins are driven, the amount of adhesive provided by each slug will be just enough to completely fill the interstitial spaces between the anchor pin and inner wall of the borehole, accounting for penetration of some adhesive into the borehole wall.
