  • Patent number: 9481972
    Abstract: In one embodiment, a pile splicing system and method uses a pile segment adapted to form part of a spliced pile, the pile segment including an elongated concrete body having first and second ends, one-way anchor embedded in the body that is adapted to resist passage of a post-tensioning strand in a direction toward the first end of the body; and a splicing duct embedded in the body that extends from the first end to the embedded one-way anchor.

  • Patent number: 6783273
    Abstract: A method for detecting and locating foreign inclusions in a drilled cylindrical shaft includes the steps of positioning at least one logging tube within the drilled shaft in parallel relation to a longitudinal axis of the drilled shaft, providing a temperature sensing means, identifying a plurality of temperature locations along the extent of the logging tube, pouring concrete into the drilled shaft, covering the at least one logging tube and monitoring in real time the temperature at various depths and radial directions within the logging tube during the hydration phase of the concrete curing. Temperature readings that differ from expected readings are deemed positioned in the vicinity of an anomalous inclusion. The range over which these anomalous readings are detected, the magnitude of the variance, and the orientation are used to predict the size and location of anomalies prior to the full curing of the concrete.

  • Patent number: 6386043
    Abstract: A lateral motion sensing assembly for sensing movement experienced by a structural member such as a support beam or driven pile. The sensing assembly is immersed within a casing which is mounted to the structural member. The sensing assembly includes a support body and an accelerometer mounted to the support body for measuring movement of the structural member. The accelerometer is aligned with an anticipated line of motion such that measurements can be made along this line of motion. A pair of lever arms are pivotally mounted to the support body for removably securing the support body within the casing. A spring is mounted between the support body and lever arms for continuously biasing the lever arms to a position perpendicular with the support body.
