A root-like expandable foundation pile is disclosed. It includes a movable drill, a foundation body, a number of foundation blade, a foundation cap and a stopper. The foundation blades are designed to have the warped portion protruding outward, so that they can expand outward by rotating the root-like expandable foundation pile in a direction different from that makes the root-like expandable foundation pile drilled into the soil. Extra bearing capacity can be available from the expanded foundation blades. Time and cost of installation can both be saved.

A modular slab, slab system, piles and methods of use thereof are described along with specific applications and methods of manufacture. The slab or slab system may be pre-insulated and pre-finished before being assembled on site. The slab system may be advantageous to use as a replacement for traditional in-situ poured building foundations. The slab system may also have uses in other fields such as for floors, roads, bridges, pavements/side walks and other civil and structural applications.

A device for stabilizing a metal pier installed in the ground. The device includes a device to provide lateral support to the pier and a shaft configured so that a force imposed, parallel to an axis of the pier, on the device is not imposed on the pier. A method of stabilizing a pier installed in ground to support a structure. The method includes determining the location of an unstable soil zone of the ground and a stable soil zone of the ground. The method also includes placing a stabilizing plate in the unstable soil zone to provide lateral support to the pier. A device configured to lift a foundation slab above the ground. The device includes a lifting bolt and apparatus that restricts lateral deflection of the pier when a torque is applied to the lifting bolt to raise the slab. A method of stabilizing soil around a pier.

A system for and method of stabilizing rail track structures using a load transfer apparatus is disclosed. The load transfer apparatus includes a vertical load transfer element and a top load transfer element, wherein the top load transfer element is used to transfer applied locomotive and rail car loads to the vertical load transfer element. In one embodiment, the top load transfer element includes helical flights. In another embodiment, the top load transfer element includes a flared top. In yet another embodiment, the top load transfer element includes a load transfer cap. In a further embodiment, the top load transfer element includes two or more support legs each with a top support attached thereto. The railroad stabilization system can comprise any one type or any combinations of types of the aforementioned load transfer apparatuses.

A support assembly for supporting a building structure, the building structure having a support frame including at least one support beam, the support assembly comprising: a pile adapted to be buried into a ground surface, the pile having a longitudinal axis; a pile head adapted to be secured to a top end of a pile, the pile head including a mounting member engaging the pile and an extendable member movably mounted to the mounting member, the extendable member being movable relative to the mounting member, along the longitudinal axis, the extendable member including: a support platform adapted to receive the support beam of the mobile home's support frame thereon; and at least one holding member adapted to engage the support beam and prevent movement of the support beam relative to the support platform.

A system for simultaneously driving multiple piles into the ground to create A-frame type structures that are anchored by piles running at angles to one another and to the ground. The system comprises a guide assembly and an actuator for driving the piles into supporting ground at the same time. The actuator may engage slots or teeth in the pile to drive them into the ground and/or may apply torque and downward pressure.

The Open End Friction Pile comprises of four steel plates, four brackets, and one driving head. The steel plates have a first bend line and a second bend line that are equidistant from a distal end. The first bend line and second bend line of the steel plates are equidistant from each other creating a center portion. The brackets have a first bend line and a second bend line that are equidistant from a distal end. The first bend line and second bend line of the brackets are equidistant from each other creating a center portion. The bracket has a third bend line along the center portion. One bracket is connected to one steel plate along the distal ends and center portion. All four steel plates and four brackets concurrently connect along the distal ends to form two open-ends. A driving head is connected covering the top open-end.

Fiber optic sensors are used to monitor the integrity of a subsurface concrete structure such as a pile or diaphragm wall. A fiber optic sensor array (48) is attached to a reinforcement or framework assembly (20) for the subsurface concrete structure. Concrete is applied to surround the reinforcement or framework assembly (20) and fiber optic sensor array (48). The fiber optic sensor array (48) is then used to collect temperature data during hydration of the subsurface concrete structure. The temperature data is monitored in real time to determine differentials across the structure, indicative of a problem within the structure.
