ABSTRACT:
A method for placing probes, sensors, transducers, and other kinds of instruments in a bore hole is disclosed as including a sleeved-port piping system, also known as a tube-a-manchette, about which isolation packers are placed around selected sleeve-port locations. The instruments that are to be installed underground are attached to the exterior of the packers and the piping system is then lowered into the bore hole. A chemical grout injector is then lowered into the piping system and chemical components are supplied, under pressure, to the injector where they are reacted to produce a chemical urethane grout that is ejected from the injector out through an adjacent sleeved-port and into each of the packers. As the packer is filled with urethane grout it expands and tightly presses the instruments against the walls of the bore hole. The grout hardens and remains viable for decades of time. After all of the packers have similarly been filled with urethane grout, the injector is used to fill the annulus i.e., the remaining space between the outside of the piping system and the walls of the bore hole with additional urethane grout that is ejected from the piping system out through some or all of the remaining sleeved-ports, thereby sealing the bore hole. The injector is itself removed from the piping system.
