## Abstract

A system and method to enhance the structural performance of a reinforced concrete pile in a ground hole is provided. The ground hole includes an upper shaft cavity connected to a lower bell-shaped cavity. The concrete pile includes a cage assembly disposed within the hole in the ground surface and includes a plurality of rebars coupled together by a plurality of fixtures. Each fixture has a generally hexagonal sheet with a plurality of fingers connected to the sheet at corner junctions with each having a concave edge. Each rebar is designed to secure within the concave edges of the corner junctions of the plurality of fixtures. Concrete is disposed within the ground hole to secure the cage assembly therein, thereby enhancing the structural performance of the reinforced concrete pile by minimizing shear stress failure and enhancing load-bearing capacity of the pile.

## Claims

### Claim 1

A deep foundation reinforced concrete pile with enhanced structural performance for use in a hole in a ground surface, the hole comprising an upper shaft cavity connected to a lower generally bell-shaped cavity, the deep foundation concrete pile comprising:
a cage assembly disposed within the hole in the ground surface, the cage assembly comprising:
a plurality of rebars coupled together by a plurality of fixtures and extending through the upper shaft cavity and the lower bell-shaped cavity, each fixture comprising a sheet comprising a plurality of fingers extending from an outer edge of the sheet, each finger in the plurality of fingers connected to the sheet at a corner junction comprising a concave edge formed by the finger and outer edge of the sheet, each finger in the plurality of fingers comprising a plurality of retaining protrusions on the concave edge of each fixture, the plurality of retaining protrusions configured to contact one of the plurality of rebars secured therein, the plurality of fixtures oriented so the plurality of fingers of each fixture are aligned with the plurality of fingers in an adjacent fixture in the plurality of fixtures, each rebar in the plurality of rebars configured to be secured within the concave edges of the corner junctions of the plurality of fixtures; and
concrete disposed within the hole in the ground to secure the cage assembly therein, thereby enhancing the structural performance of the reinforced concrete pile by minimizing shear stress failure and enhancing load-bearing capacity of the pile.

### Claim 2 (depends on 1)

The deep foundation concrete pile of claim 1, wherein each rebar in the plurality of rebars comprises an upper handle section positioned above the ground surface continuously connected to a neck section extending through the upper shaft cavity continuously connected to a lower bent section extending outward into space within the bell-shaped cavity of the hole.

### Claim 3 (depends on 2)

The deep foundation concrete pile of claim 2, wherein each fixture in the plurality of fixtures comprises a generally hexagonal-shaped sheet with a central opening, the central opening comprising an edge with a plurality of inner hooks, each rebar in the plurality of rebars configured to be secured within the inner hooks of the plurality of fixtures.

### Claim 4 (depends on 3)

The deep foundation concrete pile of claim 3, wherein each finger in the plurality of fixtures comprises a foldable tab configured to contact a sleeve disposed in the upper shaft cavity of the hole.

### Claim 5

A method to enhance structural performance of a deep foundation reinforced concrete pile in a hole in a ground surface, the hole comprising an upper shaft cavity connected to a lower generally bell-shaped cavity, the method comprising:
providing a cage assembly, the cage assembly comprising:
a plurality of rebars coupled together by a plurality of fixtures, each rebar in the plurality of rebars comprising an upper handle section continuously connected to a neck section continuously connected to a lower bent section, each fixture comprising a sheet comprising a plurality of fingers extending from an outer edge of the sheet, each finger in the plurality of fingers connected to the sheet at a corner junction comprising a concave edge formed by the finger and outer edge of the sheet, each finger in the plurality of fingers comprising a plurality of retaining protrusions on the concave edge of each fixture, the plurality of retaining protrusions configured to contact one of the plurality of rebars secured therein, the plurality of fixtures oriented so the plurality of fingers of each fixture are aligned with the plurality of fingers in an adjacent fixture in the plurality of fixtures, each rebar in the plurality of rebars configured to be secured within the concave edges of the corner junctions of the plurality of fixtures;
disposing the cage assembly into the hole in the ground surface so the upper handle sections of the plurality of rebars remain above the ground surface, the neck sections of the plurality of rebars extend within the upper shaft cavity of the hole, and the lower bent sections of the plurality of rebars extend within the lower bell-shaped cavity;
rotating the upper handle sections of the plurality of rebars to permit the lower bent sections of the plurality of rebars to extend outward into space within the bell-shaped cavity of the hole; and
disposing concrete into the upper shaft cavity and lower bell-shaped cavity of the hole.

### Claim 6 (depends on 5)

The method of claim 5, further comprising maneuvering the cage assembly so the lower bent sections of the plurality of rebars do not contact the bottom of the bell-shaped cavity.

### Claim 7 (depends on 6)

The method of claim 6, wherein each fixture in the plurality of fixtures in the cage assembly comprises a generally hexagonal-shaped sheet with a central opening, the central opening comprising an edge with a plurality of inner hooks, each rebar in the plurality of rebars configured to be secured within the inner hooks of the plurality of fixtures.

### Claim 8 (depends on 7)

The method of claim 7, further comprising inserting a tube within the shaft cavity of the hole so the plurality of fingers of the plurality of fixtures contact the tube.
