摘要： Embodiments relate to a method and apparatus for investigating the uniformity of concrete and/or grout. Embodiments can identify the existence of one or more anomalies in the uniformity of concrete and/or grout, and/or determine or estimate the size, shape, type, and/or location of one or more anomalies in the uniformity of concrete and/or grout. Embodiments can utilize a string of temperature measuring sensors placed within one or more access bore(s), such as tube(s), positioned at least partially within the concrete and/or positioned proximate the concrete. The measurements obtained from the temperature measuring sensors can then be used to assist in the identification of existence of, size of, type of, shape of, and/or location of anomalies in the concrete and/or grout.

摘要： In a machine for driving screw anchors and other foundation components, a desired embedment depth is calculated based on a minimum required embedment depth, work point height and length of available upper leg sections. Once calculated, the machine automatically drives the screw anchor to the depth so that one of the available upper leg lengths will fit between the driven screw anchor and apex truss hardware. If uplift is detected during driving, the machine will add additional embedment depth. In-situ validation of driven screw anchors may be performed after the embedment depth is reached.

摘要： The embankment monitoring system comprises an optic sensor chain (10) and an interrogator (20). The optic sensor chain (10) comprises a series of intrinsic fiber optic sensors (12) that are mutually spaced with respect to each other in a longitudinal direction of the optic sensor chain and at least one optic fiber (14) to optically connect the plurality of intrinsic fiber optic sensors to the interrogator. The interrogator is configured to issue an optic interrogation signal and the intrinsic fiber optic sensors are configured to respond to the optic interrogation signal with an optic measurement signal that is indicative for at least one physical parameter (P1) sensed by the intrinsic fiber optic sensors. The interrogator is further configured to process the optic measurement signals of the intrinsic fiber optic sensors to estimate a depth (d) as a function of a position (p) along said optic sensor chain (10).

摘要： Disclosed is a cavity-type load box, comprising an oil cavity unit. The oil cavity unit comprises a sealing plate with a U-shaped section and two flat plates with edges wrapped in the sealing plate and is provided with an oil injection structure. Liquid oil injected from the oil injection structure flows into the oil cavity unit. Herein, a top flat plate refers to the uppermost flat plate. The edges of the two flat plates are wrapped in the sealing plate with the U-shaped section, so that after the liquid oil enters an oil cavity via the oil injection structure, the sealing plate is stretched under the pressure of the liquid oil to cause deformation of the oil cavity; and as a stress required for deformation of the sealing plate is very small, the pressure generated by the liquid oil directly acts on an object on the upper or lower surface of the cavity-type load box, and accordingly, the object is pushed.

摘要： A foundation shift detection device includes a foundation portion attached to a foundation to be monitored, a base portion attached to a base adjacent to the foundation and supporting the same, and a rotary indicator attached to the base portion and adapted for rotation responsive to displacement of the foundation relative to the base. The rotary indicator is visible to a casual or walking inspection from a moderate distance, as by a human inspector making a walking inspection of a number of such devices.

The slide stop of the driving member is spaced apart from and disposed above the anchor. The anchor rod is permanently coupled to the anchor. The slide collar is disposed on the driving member and is selectively affixed to the driving member with a release mechanism. The load cell is permanently coupled to the slide collar and selectively coupled to the anchor rod. The load cell is configured to measure a load through the anchor rod during a setting operation of the anchor.
