    摘要： A post-tensioned tube foundation for supporting a structure subject to high upset forces is described herein. The post-tensioned tube foundation includes an outer CMP, an inner CMP, and a tubular concrete base positioned between the inner CMP and the outer CMP. The outer CMP includes an inner surface that defines a cavity extending between a first open end and an opposite second open end. The outer CMP is positioned within an excavated hole defined along a ground surface. The inner CMP is positioned within the cavity of the outer CMP such that an annular space is defined between the inner CMP and the outer CMP. The tubular concrete base is positioned within the annular space defined between the inner CMP and the outer CMP. A plurality of bracing beams extend radially outwardly from the tubular concrete base.

    摘要： A pile splice section for a spliced prestressed concrete pile includes a prestressed concrete element including a first end and a second end and a plurality of tendons that extend from the first end to the second end. A first end assembly at the first end of the prestressed concrete element includes a first plate coupled to the plurality of tendons. The first end assembly further includes a plurality of internally threaded fasteners embedded in the first end of the prestressed concrete element that are engagable via apertures extending through the first plate. A second end assembly at the second end of the prestressed concrete element includes a second metal plate coupled to the plurality of tendons. The second end assembly further includes a plurality of apertures extending through the second plate and accessible via pockets proximate the second end of the prestressed concrete element.

    摘要： A self-piloting compressible piling is provided comprising a plurality of pre-formed pile sections having bores therethrough and adapted to be arranged in end-to-end relation such that the bores are concentrically collinear. An auger plate is positioned beneath the lowest of the sections and has an upper face and lower face. The lower face of the plate has a plurality of curved blades extending therefrom. The plate further has a flared bore concentrically collinear with the bores of the piling sections through its center such that the diameter of the hole is greater on the upper face than on the lower face. A tension-bearing cable having a collapsible lock-jaw mechanism secured to one end thereof is provided which is extendable from above the highest of the piling sections through the bores of the sections and the bore of the plate and engageable with the lower face of the plate for loading the sections and the plate in compression.

    摘要： Provided is an anchor assembly having a pre-stressed mandrel, which consists of an inner pre-stressed concrete mandrel and an outer cast-in-place anchoring slurry, wherein pre-stressed tendons are arranged inside the concrete mandrel and are prefabricated by a pretensioning method; the anchoring slurry wraps the pre-stressed concrete mandrel, and the cast-in-place anchoring slurry is formed by placing the pre-stressed concrete mandrel in a pile hole, and solidifying after primary grouting or secondary grouting. According to the anchor assembly, the pre-stress is not required to be tensioned and locked on site, so that the quality of the pre-stressed mandrel can be ensured, the on-site construction period can be greatly shortened, and the existing pre-stressed and common non-pre-stressed anchors can be replaced.
