A load bearing clamp including a first clamp member, the first clamp member including a first semi-annular clamping surface, a second clamp member, the second clamp member including a second semi-annular clamping surface, the second semi-annular clamping surface opposing the first semi-annular clamping surface and at least one member for drawing the first clamp member and the second clamp member toward each other, wherein at least one of the first semi-annular clamp surface and the second semi-annular clamp surface includes at least one irregular surface that deforms at least a portion of a shaft clamped between the first and second clamp members.

Load bearing clamp for transmitting loads to a shaft

The present disclosure provides a load bearing clamp including a first clamp member, the first clamp member including a first semi-annular clamping surface, a second clamp member, the second clamp member including a second semi-annular clamping surface, the second semi-annular clamping surface opposing the first semi-annular clamping surface and at least one member for drawing the first clamp member and the second clamp member toward each other, wherein at least one of the first semi-annular clamp surface and the second semi-annular clamp surface includes at least one irregular surface that deforms at least a portion of a shaft clamped between the first and second clamp members.

Soil displacement piles having a shaft and one or more soil displacement assemblies secured to the shaft are provided. If more than one soil displacement assembly is utilized, each soil displacement assembly is separated by a longitudinal distance. Each soil displacement assembly has an upper helical plate, a lower helical plate and separated from the upper helical plate by a longitudinal plate distance, and at least one soil displacement plate positioned relative to the shaft, the upper helical plate and the lower helical plate.

The present disclosure provides a lateral support for a shaft of a helical pile, the lateral support including a tubular portion for receiving the shaft and a plurality of fins extending from the tubular portion.

Supports for helical piles and anchors

Soil displacement piles having a shaft and one or more soil displacement assemblies secured to the shaft are provided. If more than one soil displacement assembly is utilized, each soil displacement assembly is separated by a longitudinal distance. Each soil displacement assembly has an upper helical plate, a lower helical plate separated from the upper helical plate by a longitudinal plate distance, and at least one soil displacement plate positioned relative to the shaft, the upper helical plate and the lower helical plate.

Soil displacement piles having a shaft and one or more soil displacement assemblies coupled to the shaft such that the one or more soil displacement assemblies are movable relative to the shaft are provided. Each soil displacement assembly has an upper plate, a lower plate, a reamer between the upper and lower plates and secured to each plate, and at least one soil displacement arm extending from the lower plate.

Pile with soil displacement assembly

A coupling assembly for connecting first and second members of a helical pile system. A coupling member has a first opening at a first end and a second opening at a second end. A hollow protrusion extends outwardly from and axially along the outer surface of the coupling member. A fastener opening is disposed in the coupling member. A first member is fixedly receivable by the first opening of the coupling member. A second member has a rib disposed on an outer surface. The rib is receivable by the protrusion when the second member is received by the second opening of the coupling member. A fastener is receivable in the fastener opening. The fastener prevents withdrawal of the second member after being inserted in the coupling member.

Coupling assembly for helical pile system

A helical screw pile having a soil displacement device (lead displacement plate) on its shaft above at least one helical plate, which pulls the pile into the ground when the shaft is rotated. The lead displacement plate has a disk that carries at least two curved, axially extending bottom blades, which preferably extend beyond the disk periphery. The axial height of the blades preferably is greater than the axial pitch of the helical plate(s) divided by the number of blades. The top of the disk has an axially extending adapter ring that defines an annular seat for centering a tubular casing. Extension displacement plates can be used between extension shafts for centering additional tubular casings.

An improved transition coupling for a helical soil pile assembly transfers a compression load between two coupled shaft segments with little or no compression loading on the bolts that fasten the parts together. The coupling body has a shaft-receiving socket that extends axially into the body from one end to a socket bottom that axially abuts the end of one of the shafts. The body also has at least one shoulder between its ends that extends laterally outward and faces toward the end remote from the socket. A cylindrical portion of the body, which fits closely within the hollow end of the other shaft, extends axially toward the socket end up to the shoulder, which is adapted to abut the end of that shaft. At least one pair of aligned transverse holes in the body is adapted to receive a fastener.

Transition coupling between cylindrical drive shaft and helical pile shaft

An adapter for connecting a helical pile to a drive assembly includes a pin block connectable to the helical pile. A tool body has a first protrusion to receive the pin block to facilitate aligning the helical pile with the tool body. A locking member is movably connected to the tool body. The locking member is movable between an insertion position to allow insertion of the pin block and a locking position to lock the pin block in the tool body.

Helical pile adapter

A pipeline buoyancy control assembly is operable to simultaneously retain a plurality of pipelines against buoyancy forces. Respective ends of two retaining straps corresponding to two respective pipelines engage a tie-down member of a single control assembly. The retaining straps are placed over the respective pipelines and other ends of the retaining straps are attached to additional control assemblies. Further, stresses exerted on the retaining straps when the pipelines are subjected buoyancy forces are minimized by the unique structure of the tie-down member and the manner by which the retaining straps attached thereto.
