A system and method used to translate a building structure (e.g., a single-family home) from a first position (e.g., above grade) to a second position (e.g., below grade) is provided. The system may thereby protect building structures from above grade threats such as wildfires, tornados, hurricanes, and other threats by lowering the building structure into a below grade cavity and sealing it therein. The system may include a base that supports the building structure and a translation system that lowers the base and the building structure below grade. The translation system may include scissor lifts, hydraulic lifts, jackscrew lifts and/or other types of lifts. The system also may include a quick release utilities system to disconnect the various utilities during the translation and a protective roof that may be extended over the top of the building structure to protect it from the threats above.

Described are an apparatus and method for driving piles prior to lifting and stabilizing foundations that have subsided in unstable ground. A press head, comprising two non-slip arms actuated by a safety lever, is connected to an angle cleat-type foundation piece secured to the foundation by a pair of hydraulic rams in order to drive the piles into the ground as far as the bedrock when the rams contract. The apparatus includes a safety system actuated by the lever for controlling the arms. In order to level the building, other hydraulic rams are installed on each driven pile, all connected in series in order that they may be actuated simultaneously in order to lift the building. When the foundations have been adequately raised and levelled, each pile and the corresponding angle cleat-type foundation piece, both made of steel, are welded in order to stabilize the foundations.

The disclosure provides a core-pulling transfer device for reverse demolition of reinforced concrete structures and a construction method. The device comprises temporary supports, long-stroke hydraulic jacks and steel crossbeams, wherein the temporary supports are supported on bottom surfaces of bottom crossbeams of the reinforced concrete structure, a beam end through hole is formed in each end, connected with a force-transmitting structure column, of each bottom crossbeam, two long-stroke hydraulic jacks are symmetrically arranged on both sides of each force-transmitting structure column, core-pulling holes are formed in upper end sides of demolition floor structure columns, one steel crossbeam is in clearance fit with each core-pulling hole, both ends of each steel crossbeam extend out of the corresponding core-pulling hole, lower surfaces of the long-stroke hydraulic jacks are fixedly connected to a foundation, and upper surfaces of oil cylinders of the long-stroke hydraulic jacks are propped against lower surfaces of the corresponding steel crossbeams after moving up and penetrating through the corresponding beam end through holes. The disclosure can quickly carry out vertical load transfer of the reinforced concrete structure, smoothly transfer vertical force, and achieve a safe reverse demolition construction process.

A device for moving a building module along the ground, the device includes: a first frame member and a second frame member, spaced apart from the first frame member. The device also includes a first wheel assembly having at least one first wheel, the first wheel assembly being operatively coupled to the first frame member, and a second wheel assembly includes at least one second wheel, the second wheel assembly being spaced apart from the first wheel assembly and operatively coupled to the second frame member. The device further includes at least one cross-member having a first end removably secured to the first frame member and a second end removably secured to the second frame member.

A modular foundation support system includes modular foundation support components including self-aligning and torque transmitting coupler features wherein a plurality of axially elongated ribs are aligned with a plurality of axially elongated ribs to rotationally interlocke the modular foundation support components to one another.

The present invention relates to a foundation reinforcing apparatus using a bracing-type supporting structure and a lateral prestressing device and a foundation reinforcing method using the same, wherein, in the foundation reinforcement used for remodeling construction that requires an extension of a building such as an apartment, the foundation reinforcing apparatus introduces lateral pre-stressing force into a bracing-type supporting structure to introduce a preloading load to a new pile of a new footing by using an upper supporting plate, which is connected to an existing vertical part and an existing slab, as a reaction bed and allows the new pile to share a load applied before and after the extension of the building so that reinforcement efficiency is increased, and thus construction is performed economically.

A robotics-assisted foundation installation system is provided in which data reporting the X, Y, and Z positions of foundation column tops are sent from a total surveying station to a grid control system. The grid control system receives the data and associates specific data with specific columns in an arraythe grid. The grid control system compares the actual positions of the columns in the grid to target positions that were determined based on the requirements of the structure to be supported. After determining differences between the actual positions and the target positions, the grid control system sends instructions to column positioning tools associated with the individual columns. Actuators in a column positioning tool are directed by the grid control system to adjust the position of the associated column. Once the live streamed data confirms that each column is in the proper position, the columns are fixed in place.

A modular foundation support system includes modular foundation support components including self-aligning and torque transmitting coupler features wherein a plurality of axially elongated ribs are aligned with a plurality of axially elongated ribs on a second distal end to rotationally interlocked the modular foundation support components to one another. First and second pair of fastener holes are self-aligning with one another to receive a fastener therethrough such that the fastener is mechanically isolated from rotational torque transmission.
