A system for lifting and moving a pre-tensioned concrete a foundation system comprising a pair of bridles secured to ends of the foundation, at least one lifting tendon spanning the underneath the foundation between the bridles and lifting arms attached to the bridles and tendon to apply a compressive clamping force to the foundation while lifting the foundation.

Disclosed in the present invention is a lifting and reinforcing process for a dust-free factory floor, including: reinforcing a soft foundation and precisely lifting a settlement range. Reinforcing a soft foundation includes: step 1: determining a depth of a soft soil layer in an inner settlement area of the factory, and designing a drilling curve; step 2: drilling guiding holes from the outer construction point of the factory; step 3: connecting and communicating grouting channels; and step 4: grouting. Lifting a settlement area includes: step 1: determining a depth range between the reinforced soft foundation and the floor, and designing the drilling curve; step 2: drilling the guiding holes; step 3: connecting and communicating the grouting channels; step 4: starting grouting; and step 5: stopping grouting.

Methods and Systems provide for a Rapid Deployment Robotic Self-Installing and Self-Leveling Payload Structure (hereinafter, RDR-PC) anchors a payload structure to site with no prior site preparation. The RDR-PC is ideal for remote, and/or difficult installations-whether on/off world-where deployment/development speed is critical and prior access to site is impractical, limited, or impossible. Leave-no-trace removal of the same system is achieved by reverse process.

In one embodiment, a variable height pier leg extension apparatus provides adjustable leg extension to a plurality of bridge panel components each having two panel bridge pier legs for a panel bridge pier. The bridge panel components are disposed in a panel bridge pier leg configuration. The variable height pier leg extension apparatus comprises a plurality of variable height pier leg extension frames arranged in the panel bridge pier leg configuration and to be attached to a pier foundation, each variable height pier leg extension frame including a plurality of vertically spaced mounting locations to be selected to elevate the panel bridge pier legs of the bridge panel components relative to the pier foundation; and a plurality of mounting members to mount the panel bridge pier legs of the bridge panel components to the variable height pier leg extension frames at selected mounting locations to elevate the panel bridge pier legs to provide a selected elevation for the bridge panel components of the panel bridge pier.

A modular foundation support system includes modular foundation support components including shafts provided with integrally formed coupler features on their respective distal ends. The coupler features are configured with a non-uniform wall thickness defining a plurality of sections of respectively different diameter to matingly couple the shafts to one another in a torque transmitting relationship. The coupler features may be integrally formed and fabricated on the distal end of each respective shaft.

A device and methods for raising an underground footing or foundation beneath a structure such as a home, office building or roadway, using a means of pumping expandable fluid into substratum below the area to be raised. The device includes an elongated shaft comprising a trailing end and a leading end and may define a fluid pathway from the upstream trailing end to the downstream leading end. The trailing end is adapted to secure fluid communication between the fluid pathway and the means of pumping expandable fluid may include. The fluid pathway terminates in a downstream fluid pathway exit, in a section of the leading end having a reduced diameter smaller than a diameter of the leading end upstream from said fluid pathway exit. The leading end further comprises a tip region converging to a point facilitating pushing of the leading end deeper into the substratum. The enlarged diameter of the leading end upstream from the fluid pathway exit defines an obstacle to upstream travel of the expandable fluid outside the fluid pathway exit, thereby containing the expandable fluid in the area beneath the footing to be raised. Besides the initial pushing of the leading end of the shaft into the substratum, the method for raising the footing also includes initially injecting a relatively smaller amount of expandable fluid at the initial depth, allowing the fluid to expand and solidify, then pushing the shaft further into the substratum to a deeper depth for injection of additional expandable fluid beneath the initial treatment area. This facilitates the raising of the initial treatment area rather than just the area of current injecting.

The present application relates to a method for lifting a factory building floor in a weak soil layer geology, including: S1, measurement: measuring a settlement numerical value of a floor of a factory building and a depth of a weak soil layer; S2, determining grouting point locations: marking grouting point locations on a ground of the factory building, with equal distances between adjacent point locations; S3, inserting grouting pipes: inserting a plurality of grouting pipes at the grouting point locations, the grouting pipes passing through the weak soil layer and abutting against the bearing layer; and S4, grouting: forming support columns by grouting into the grouting pipes, while simultaneously withdrawing the grouting pipes from the weak soil layer.

An engineering method for reinforcing and lifting a sunken foundation of a residential building includes stratigraphic structure, conducting a curtain reinforcement, reinforcing and strengthening a shallow layer, reinforcing a deep layer, steadily lifting an intermediate layer, and reinforcement supports of the composite foundation, the shallow layer reinforcement and strengthening adopts a progressive layered reinforcement process, the foundation slab of the building is reinforced with grouting to form the reinforcement body of an integral raft composite foundation.
