Abstract

A chemical anchoring assembly useful for fast application of a driving tool into a borehole includes an elongated tube having a first end and a second end, a quantity of chemical anchoring material within the elongated tube, and a vent at the second end of the elongated tube. As an anchor pin is driven through the elongated tube and into the borehole, forcing the chemical anchoring material into the borehole, some of the pressure caused by compression of the chemical anchoring material is released into the vent, allowing easier driving of the anchor pin.
