CARTRIDGE FOR GROUTING AN ANCHOR ELEMENT IN A HOLE OF A SUPPORT STRUCTURE

A grouting cartridge is described for placing in a hole of a support structure. The cartridge is capable of rapidly forming a solid grout about an anchor element where the anchor element is thrust into the hole. The cartridge comprises a frangible outer tubular casing fabricated of plastic or the like and containing a uniform mixture of a water-hardenable cement and a multitude of frangible microcapsules which hold droplets of water. One or more of these cartridges is placed in the borehole, and the anchor element in a one-step operation is inserted therein, and preferably rotated, to pierce the casing and rupture the microcapsules to uniformly wet the cement to form a cement paste. The cement paste under the pressure of the anchor element flows into intimate contact with the hole wall of the support structure and into intimate contact with the surfaces of the anchor element. The cement paste rapidly solidifies forming a solid grout between the support structure and the anchor element to affix the anchor element securely to the support structure.
