Abstract
Piles and methods for installing them appear. An alternative pile has a lead section driven a depth below the soil surface, and then a reinforcing structure such as a rebar cage is placed above the lead section. Liquid grout is allowed to harden in contact with the reinforcing structure, thereby forming the pile. Reinforcing structure extending above the surface of the soil can tie in supported structure, such as pile caps, reinforced columns, and cmu columns, for example.
Claims20
A method for constructing a pile in soil, comprising:
- driving a lead section comprising a shaft having a flight of helical screws between a top end and a bottom end into the soil, thereby forming a hole in the soil about the lead section, wherein the lead section is joined to a driving section that applies force to the lead section;
- optionally adding one or more extension sections between the lead section and the driving section, wherein the one or more extension sections are joined at a lower end to the lead section and are joined at an upper end to the driving section;
- wherein the top end is a depth below a surface of the soil;
- uncoupling the lead section from the driving section or, if present, from the lower end of the one or more extension sections;
- removing the driving section and, if present, the one or more extension sections from the hole;
- adding a reinforcing structure to the hole,
- thereby forming the pile in the soil.

A pile in soil, comprising:
- a lead section disposed in the soil, comprising a flight of helical screws between a top end and a bottom end defining a shaft,
- wherein the top end is a depth below a surface of the soil;
- a reinforcing structure having a first end proximal to the top end of the lead section and a second end proximal to the surface of the soil;
- and
- grout in contact with the reinforcing structure.
