A post foundation system is provided. The system has a shaft with a helical disk attached to one end and a post support attached to the other end. The helical disk drives the shaft into the ground as a rotational force is applied to the shaft. A fin section is rotatably coupled about the shaft between its first and second ends. The fin section can have one or more fins extending outwardly from the shaft. The fin section engages the ground to stabilize the post foundation system as the shaft of the post foundation system is driven into the ground.

A pile system for support structures includes at least two piles each having a first end, a second end, and a cylindrical elongate body. Each cylindrical elongate body has an inner surface and an outer surface, extends from the first end toward the second end, and defines an internal cavity with a longitudinal axis. Each pile further includes a transition region between the elongate body and the second end, the transition region including an annular seating shoulder disposed on the inner surface of the cylindrical elongate body that defines a step increase from a primary inner diameter to a secondary inner diameter. The first end of a first pile of the at least two piles is configured to be inserted into the second end of a second pile until a first distal edge thereof contacts the seating shoulder of the second pile.

A template for installing piles underwater includes a template frame and pile guides having parallel pile guide centerlines and being fixed to the template frame. Each pile guide has a pile guide frame that surrounds a passageway configured for passing a pile therethrough. Each pile guide frame includes upper and lower ends. Each pile guide includes a spacer fixed to the pile guide frame and protruding into the passageway. The spacer has a pile contact surface for guiding a pile. The pile contact surface encloses an imaginary cylinder including a centerline which coincides with the pile guide centerline. In a circumferential direction about the pile guide centerline, the location of the pile contact surface shifts with respect to the corresponding pile guide frame in a direction from the lower end to the upper end thereof as seen in a direction from the template center to the pile guide centerline.

The invention relates to a foundation engineering method and a construction apparatus for producing a columnar structure in the ground, in which a foundation engineering tool is driven in a rotating manner about an axis of rotation and introduced with a feeding motion into a ground, wherein the columnar structure is produced in the ground. According to the invention it is provided that during the production of the columnar structure a rotating motion and a feeding motion of the foundation engineering tool are recorded over time and forwarded to an evaluation unit, in that by means of a sensor means at least one further processing parameter is recorded over time during the production of the columnar structure in the ground and is forwarded to the evaluation unit and in that by the evaluation unit a three-dimensional model of the columnar structure is produced and displayed.

A device for levelling an offshore foundation construction including a cylinder equipped with a fastening member for removably fastening the cylinder to a part of the offshore foundation construction, a rod mobile in axial translation with respect to the cylinder, the rod including a pushing end so configured to push against a mudmat.

An erosion control roll comprises a porous outer casing having an interior, a fill material within the interior, wherein the fill material comprises a mineral wool. The erosion control roll is flexible and positionable where it can provide one or more of erosion control, sediment separation, water flow diversion, and a fire barrier.

A foundation for a windmill includes an annular pedestal, which is divided into several ring sections and is composed of prefabricated concrete elements, the pedestal including a platform for a windmill tower and several support elements extending radially outward from the pedestal, wherein the pedestal is supported by strut ribs on the support elements, wherein the pedestal, at its end forming the platform, includes a circumferential projection extending radially outward from the pedestal and including at least one channel for receiving a tensioning cable, the channel being provided in the projection and extending in the circumferential direction.

A foundation support system and method of installing the foundation support system. The foundation support system includes a pier system for providing support beneath a foundation, a support member, and a heave plate attachable to a bottom surface of the foundation. The method includes driving a pier system using a ram, coupling a support member to the heave plate, and engaging the support member with the pier system.

Disclosed are various embodiments of a mechanically stabilized earth (MSE) retaining wall that employ, for reinforcement, a geosynthetic strip that attaches to the MSE retaining wall and extends into the backfill soil. In one embodiment, the MSE retaining wall has at least one concrete panel. The panel has a cavity extending from the backside into the body for receiving a flexible, generally flat, geosynthetic strip. The panel has a plastic pipe (or first cylindrical body) that is situated within the body of the panel in a position so that the plastic pipe is generally horizontal from a front elevation view vantage point of the panel and is generally parallel with the backside of the panel from a top view vantage point of the panel. The plastic pipe extends through the cavity and its ends reside within the concrete panel. The MSE retaining wall further includes a steel rod situated inside of the plastic pipe. The geosynthetic strip extends from backfill soil adjacent to the backside of the panel, into the cavity of the panel, around the elongated body of the plastic pipe, out of the cavity, and into the backfill soil. In another embodiment of the MSE retaining wall, an end of the geosynthetic strip is bound to the panel with a double compression loop arrangement that utilizes an additional solid second plastic rod (or second cylindrical body).

The present disclosure discloses a fiber reinforce plastic (FRP) composite material pile prepared by an FRP composite material. The FRP composite material pile includes: an FRP winding pipe, an FRP pultrusion hollow profile, and a connecting device. The FRP pultrusion hollow profile includes an outer ring pipe, an inner ring pipe, and a plurality of reinforcing bars. The FRP pultrusion hollow profile is pultruded at one time by pultrusion equipment, and fiber materials thereof are arranged in the longitudinal direction of the pipe. The FRP winding pipe is provided with circumferential fiber materials by taking the FRP pultrusion hollow profile as a membrane, and forms a composite pipe section with the FRP pultrusion hollow profile. The inner ring shape of the cross section of the FRP winding pipe is matched with the FRP pultrusion hollow profile. The FRP connecting device includes connecting plates, connecting bars, and connecting pins.
