Abstract
A method for reinforcing an aggregate pier. The method includes inserting a conical-head pipe into the aggregate pier, injecting grout into the aggregate pier by injecting the grout into the inner chamber of the hollow rod, driving the conical-head pipe into a soil under the aggregate pier by driving a secondary pipe into the aggregate pier and pushing the conical-head pipe toward the soil under the aggregate pier by utilizing the secondary pipe, filling the secondary pipe with grout, and inserting a reinforcement bar into the secondary pipe and the hollow rod. This method reinforces an aggregate pier against excess tensional and compressional loads of a concrete foundation.
Claims11
A method for reinforcing an aggregate pier, the method comprising:
- inserting a conical-head pipe into the aggregate pier, the conical-head pipe comprising:
- a hollow rod with an inner chamber and a thorough injection hole;
- a conical head attached to a bottom end of the hollow rod;
- and
- a first plurality of T-shaped elements mounted around an outer surface of the hollow rod, each respective T-shaped element of the first plurality of T-shaped elements comprising:
- a respective rectangular-shaped plate comprising a respective rectangular face;
- a respective triangular-shaped plate comprising a first edge and a second edge, the triangular-shaped plate attached at the first edge of the triangular-shaped plate to the rectangular face of the rectangular-shaped plate, the triangular-shaped plate attached to the outer surface of the hollow rod at the second edge of the triangular-shaped plate;
- injecting grout into the aggregate pier by injecting the grout into the inner chamber of the hollow rod;
- driving the conical-head pipe into a soil under the aggregate pier by driving a secondary pipe into the aggregate pier and pushing the conical-head pipe toward the soil under the aggregate pier by utilizing the secondary pipe, the secondary pipe further comprising a second plurality of T-shaped elements attached around an outer surface of the secondary pipe, each respective T-shaped element of the second plurality of T-shaped elements comprising:
- a respective rectangular-shaped plate comprising a respective rectangular face;
- and
- a respective triangular-shaped plate comprising a third edge and a fourth edge, the triangular-shaped plate attached at the third edge of the triangular-shaped plate to the rectangular face of the rectangular-shaped plate, the triangular-shaped plate attached to the outer surface of the hollow rod at the fourth edge of the triangular-shaped plate;
- inserting a reinforcement bar into the secondary pipe and the hollow rod;
- and
- filling the secondary pipe with grout.
