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.

A swivel connector for a spray gun includes a first portion, the first portion including a first interior passage that extends entirely through the first portion along a longitudinal axis and a second a second interior passage that extends along a first axis perpendicular to the longitudinal axis. The swivel connector also includes a second portion coupled to the first portion, the second portion including a third interior passage that extends entirely through the second portion along the longitudinal axis, and a fourth interior passage that extends along a second axis perpendicular to the longitudinal axis. The swivel connector also includes a connector pin coupled to both the first portion and the second portion, wherein the connector pin includes a fifth interior passage that extends along the longitudinal axis.

The present disclosure includes systems, devices, and methods for correcting foundation heave. Some systems may include a compressed air source configured to propel air having a relative humidity that is less than or equal to 30 percent and one or more air injection devices each configured to be disposed within an earth formation to deliver the air. Some air injection devices include an elongated body having: a length that is greater than or equal to 3 feet, a sidewall that defines a conduit extending along a longitudinal axis of the elongated body, the conduit being configured to be in fluid communication with the compressed air source, and a plurality of perforations, each extending through the sidewall and in fluid communication with the conduit.

The present invention relates to a preloading apparatus and a method of reinforcing a foundation using the same, wherein, in a preloading method used for remodeling construction in which an extension of a building, such as an apartment, is required, the preloading apparatus allows adjustment of a preloading load, such as addition of a preloading load, to be performed when loss of the preloading load occurs and allows the new pile to effectively share a load applied before and after an extension of a building so that reinforcement efficiency is increased, and thus a load is adjustable 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.

Provided are a pile foundation bearing platform settlement, reinforcement, lift-up and leveling structure and a construction method thereof. The structure includes a bearing platform and a plurality of pile foundations, a weak soil reinforcement layer under the bearing platform and a pile tip bearing stratum. The weak soil reinforcement layer under the bearing platform forms a plurality of first grouting holes, and the first grouting hole extends through the bearing platform and communicates with the outside. The first grouting hole is used to perform primary grouting in the weak soil reinforcement layer under the bearing platform. The pile tip bearing stratum forms a plurality of second grouting holes, and the second grouting hole extends through the weak soil reinforcement layer under the bearing platform and the bearing platform, and communicates with the outside. The second grouting hole is used to perform secondary grouting in the pile tip bearing stratum.
