摘要:
An apparatus and method for raising and supporting the foundation or slab of a building, in which a lifting assembly engages the lower surface of the foundation or slab and is secured thereto. A piling is disposed adjacent the lifting assembly and is engaged by a driving assembly. A hydraulic ram is connected between the driving assembly and the lifting assembly in the expanded position of the ram so that when said ram is retracted, the piling is driven into the ground until it encounters a predetermined resistance. The ram is further actuated after the predetermined resistance is encountered to raise said foundation or slab a predetermined distance.

An apparatus for raising and supporting the foundation or slab of a building in which a lifting assembly is inserted underneath the foundation or slab and is adapted to receive a pipe assembly. A clamping assembly is provided for engaging a portion of the pipe assembly extending above the lifting assembly, and a hydraulic system extends between the lifting assembly and the clamping assembly for sequentially lowering the pipe assembly into the ground so that, when it encounters resistance, the foundation or slab is supported and can be raised to a predetermined level.

An apparatus for lifting and supporting a pile is provided. The apparatus includes a modular support structure, which may include a modular support element such as a modular support helical pile. The modular support structure may further include a modular guide sleeve for guiding the support element as it is driven into strata. The portions of the modular support element and the modular guide sleeve may be installed adjacent a pile supporting a building even in the confined vertical space between the bottom of the building and the surface of the ground. Lifting device elements may be attached to the modular support structure and engaged with the building pile to lift and support the building pile.

An apparatus for lifting and supporting a pile is provided. The apparatus includes a support structure coupled to the pile and a lifting device coupled to the support structure. Gripping plates of a lift head engage and lift the pile during extension of the lifting device. During retraction of the lifting device, gripping plates of a gravity vice engage the pile to support the pile in the lifted position. The extension and retraction of the lifting device is alternately repeated to lift the pile in steps to a desired height.

A system and method for supporting a pier-supported structure includes a pier support assembly for engaging a pier of the structure. The system also includes a guide assembly coupled to the pier support assembly and a piling extending through the guide assembly. The system further includes a clamp assembly adapted to engage the piling upon downward movement of the piling and a drive system coupled to the clamp assembly and the pier support assembly. The drive system is operable to drive the piling downward relative to the pier support assembly until the piling encounters a predetermined resistance.

A system for raising and supporting the foundation or slab of a building, in which a mounting assembly is bolted to the foundation or slab and includes a pair of support sleeves which receive a piling and which are connected to the foundation or slab. A clamping assembly engages the piling, and a hydraulic ram is connected between the clamping assembly and the mounting assembly in the expanded position of the ram so that when the ram is retracted, the piling means is driven into the ground until it encounters a predetermined resistance. The ram is further actuated after the predetermined resistance is encountered to raise the mounting assembly and the foundation or slab a predetermined distance after which the mounting assembly and the foundation or slab are secured to the piling.
摘要:
A system and method of installing a preconstruction support system for a building, according to which the corresponding ends of two piling sections are connected together and an a auger is provided on one or more of the piling sections. The piling sections are driven into the ground in a manner so that a portion of the uppermost piling section extends above ground; and a concrete slab encases the portion of the piling sections.

A method for moving a wall from a first position to a second position and anchoring the wall in the second position, according to which a portion of an elongated assembly is placed through an opening in the wall. An auger is provided on one end portion of the assembly and torque is applied to the assembly to cause the auger to penetrate the ground, and a nut is advanced along the assembly to engage the wall and force the wall from the first position to the second position.
