Abstract
Stabilization of sagged building foundations is carried out by raising and supporting these concrete foundations. To that effect, an L-shaped lifting assembly is bolted to the concrete to support the foundations. This lifting assembly is also formed with a vertical tubular member in which a tubular pile can slide longitudinally. An assembly of two pivotal jaws, positioned on opposite sides of the pile, is mounted above the lifting assembly. In order to drive the pile into the soil, a pair of hydraulic cylinders interconnect the lifting and jaw assemblies.
As the cylinders extend, the jaws pivot to enable the jaw assembly to slide upwardly over the pile. As the cylinders retract, the jaws pivot to grasp the pile and drive it into the soil. When the lower end of the pile reaches soil of sufficient hardness, further retraction of the hydraulic cylinders raises the lifting assembly and accordingly the foundations.
When the foundations have been adequately raised, the pile and the tubular member, both made of steel, are welded together to stabilize the foundations.
