Abstract
A method and special mechanical apparatus for installation of support pier for structure comprises positioning a hollow tube apparatus in a soil matrix wherein the hollow tube apparatus has a hollow core and is susceptible to lateral and longitudinal movement, removing soil from the hollow core and then filling that core with an aggregate followed by raising and lowering of the hollow tube apparatus by means of a special bottom mechanical device in a manner which compacts the aggregate and also applies lateral forces to the aggregate against the walls of the cavity in the soil matrix, pushing a portion of the aggregate into the soil matrix.
Claims12
A method for installation of a pier in a soil matrix comprising, in combination, the steps of:
- a) positioning a hollow tube apparatus having a longitudinal dimension and a lateral dimension in a soil matrix, said hollow tube apparatus including a hollow core and a lower end;
- b) inserting materials into the hollow tube apparatus in the soil matrix;
- c) moving the hollow tube apparatus incrementally to simultaneously impart lateral forces on the mixture within the hollow tube apparatus and longitudinal forces on the inserted materials to thereby form a compacted lift as the hollow tube apparatus is removed in an incremental step from the soil matrix;
- and
- d) repeating steps (b) and (c).
