摘要： The disclosure describes, in part, battered composite piles arranged in-line with angled legs of a tower (e.g., lattice tower). The number of battered composite piles may be equal to the number of angled tower legs of the tower, and each of the battered composite piles may attach to a respective angled tower leg and may have batter angles at angles that match an angle of the angled legs of the tower. These battered composite piles are loaded predominantly axially rather than in shear and, thus, the piles may be designed to be much smaller in size while still meeting safety requirements. In addition, the piles may be installed in less time and at a lower cost than compression/lift and shear loaded foundations.

摘要： A method and apparatus for forming a support aggregate pier having compacted aggregate lifts in a soil matrix, includes an elongate, hollow tube with a bulbous leading end bottom head element that is forced or lowered into the soil matrix. The hollow tube includes a mechanism for releasing aggregate from the lower head element of the tube as the tube is lifted in predetermined increments. The same hollow tube is then lowered or pushed in predetermined increments to vertically compact the released aggregate in thin aggregate lifts, while forcing a portion of the compacted aggregate transaxially into the soil matrix at the sidewalls of the cavity. The process may be repeated to form a series of compacted aggregate lifts comprising an aggregate pier or the process may include forming only a single lift for the aggregate pier while densifying adjacent matrix soils and imparting lateral stress in these soils.

摘要： A set of one or more reaming members is secured to a pile mandrel. Each reaming member is moveable between a first position where the reaming member extends a first distance from a center of the pile mandrel, and a second position where the reaming member extends a second distance from the center of the pile mandrel. An apparatus including a pile mandrel and one or more reaming members attached to the mandrel is driven into soil, creating a hole extending down from a surface of the soil. While the reaming member(s) are below the surface of the soil, the reaming member(s) are extended to an extended position; the pile mandrel is rotated with the reaming member(s) extended to ream a section of the hole to a second diameter that is larger than the first diameter; the reaming member(s) are retracted, and the mandrel is removed from the hole.

摘要： A method of forming a grouted pile member in unstable soil involves introducing a pile member into the ground and passing it through a first extremely unstable layer of soil into a second layer of relatively unstable material. Grout is introduced through the pile member under pressure and forms a column generally below the pile member. The pile member is then lowered into the grouted material.

摘要： The invention relates to a method of manufacturing a reinforced oblong concrete product for longitudinal load-bearing purposes, in particular a driving pile. According to the present invention reinforcing fibers are used to prevent break-up of the concrete due to radial forces which occur during driving, and the concrete composition is provided with said reinforcing fibers before the concrete composition is applied to the reinforcing wire. This method reduces the amount of heavy labour and cost. The invention also relates to a driving pile comprising reinforcing fibers.
