Benefits of technology
[0015]One advantage of the present invention is that it provides a system which is adaptable for faster, easier injection of solidifying material into a soil subsurface during the composite pier placement process, thereby achieving voidless soil stabilization, load carrying and anchorage.
[0016]Another advantage of the invention is that the composite pier can be driven into the ground surface at predetermined precise locations using easily interchangeable types of torque, hydraulic and percussion drilling machines.
[0017]Yet another advantage of the invention is that it provides a rugged yet relatively inexpensive drilling system that can be used interchangeably to form either a voidless anchor or load carry pier.
[0018]Still another advantage of the invention is that the system allows for rapid, stable and uniform construction of voidless anchors or load carry piers on all types of terrain and soil conditions.
[0019]Yet another advantage of the invention is the ease with which soil stabilization may be achieved in remote areas far removed from solidifying material mixing plants.
Problems solved by technology
Unfortunately, such post-drilling operation techniques leave voids both within the solidifying material and between the solidifying material and soil with resulting loss of soil stabilization and resistance to displacement.

Embodiment Construction
[0028]While grout is the solidifying material of choice, the present invention is not limited to use with grout. Rather, it should be apparent that any solidifying material capable of being pumped under pressure may be used. As used herein, the term “anchorage apparatus” is meant to included all shafts, drills, bits, tools and the like capable of expressing solidifying material during the drilling process, be it during insertion of the anchorage apparatus, during removal of the apparatus, or both.
[0029]Referring to FIG. 1, in a preferred embodiment, the soil stabilization and anchorage system used in the method of the present invention 10 comprises three main components: a solidifying material swivel 2 for receiving both a power drive unit 68 and a solidifying material (not shown), a drive connector 4 operatively connected to the solidifying material swivel 2, and a anchorage apparatus 6 operatively connected to the drive connector 4.
[0030]Turning to FIGS. 2 and 3, solidifying mater...

This invention relates to a method for installing anchorage apparatus used in stabilizing different types of soils and / or creating anchorage and more particularly, to a method for injecting various types of solidifying material into a subsurface through a anchorage apparatus during the drilling operation. The anchorage apparatus may be used in conjunction with grout and similar materials for forming an anchor or load carry pier. A solidifying material swivel, a drive connector and a anchorage apparatus, in combination are attached to a power drive unit such that after insertion, the anchorage apparatus remains within the soil subsurface, encased in solidifying material.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application in a continuation-in-part and claims benefit of U.S. application Ser. No. 11 / 423,323 filed Jun. 9, 2006, incorporated by reference herein.FIELD OF THE INVENTION[0002]This invention relates to a method of installing a pier anchorage system used in stabilizing different types of soils and / or creating anchorage, and more particularly, but not by way of limitation, to a method of installing a pier that permits injecting various types of solidifying material into a subsurface during its placement.BACKGROUND OF THE INVENTION[0003]Soil stabilization techniques such as helical plate bearing anchors, mini-piles and micro-piles are known. For example, helical plate bearing anchors are mounted on steel bar shafts and pipe shafts with plate helices that are drilled into soil and used as tension, compression and lateral force resisting members. These types of anchors may be mounted to hollow shafts to provide a channel for injecting s...
