Abstract
Advanced masonry coring systems for coring and grouting masonry walls are disclosed in this patent. The systems include rotating machinery and a drill column in the form of a cylindrical double-piped string of pipe sections, rotating a cylindrical drill body. The drill body mounts cutting end faces having alternative means of employing carbide or diamond cutting and/or pulverizing elements. The double drill pipe weight is made workable through new aerospace composite fabrication. The double pipe permits more efficient routing of air and removal of drill cuttings. Advancement in various system components and means of placing reinforcement into walls is disclosed. Further disclosure is included of advanced means of optimizing resin grouting materials and procedures to fill the wall cavities created by the core drill, integrating the reinforcement into the walls.
