A socket wrench attachment (SRA) is connected by a circular array of bolts () connecting the mounting flange () to the rotary output member () on a rotary output shaft (). The shaft () is a part of a rotary drive mechanism () which is mounted for longitudinal travel along a tower ().
Apparatus for placing pipe piling (′) in the ground including a support frame () and a motor () mounted on the support frame (). The motor () has a downwardly extending rotary output shaft () which extends into an opening () in a drive head (). Rotation of the output shaft () by the motor () will rotate the drive head () about a vertical axis. The drive head () is drivenly connectable to the upper end portion of the pipe piling (′). A clamping apparatus is mounted on lower side portions of the support frame. The clamping apparatus includes a pair of horizontally disposed linear hydraulic actuators (). Each actuator comprises a fixed outer end portion () and a retractable/extendable/rotatable inner end portion (). A pair of pipe piling engaging clamps () are connected to the inner end portions () of the actuators (). The clamps () confront each other across space between them. The clamps () are adapted to receive between them a section of the pipe piling (′). The actuators () can be retracted to move clamps () apart and provide between them a pipe piling receiving space. The actuators () can be extended to move the clamps () toward each other and into clamping engagement with a pipe piling (′) that has been placed into space between the clamps ().
Apparatus And Methods For Pipe Piling Placement With Continuous Grouting
A pipe assembly may have one or more pipe segments that are coupled together or coupled to a drive socket by a coupler. The bottom-most pipe segment being a bottom pile segment that may have a body with a central axis, an exterior surface an upper end connectable to the pipe pile assembly, and a bottom end, the bottom end inhibiting grout from passing through the bottom end, helical flights extending from the exterior surface of the body substantially perpendicular to the central axis, and grout ports through which the grout is emittable. The bottom pipe segment is designed to receive grout introduced through the pipe assembly so that the grout can be emitted the grout ports during the driving of the pile assembly into soil. The emitted grout forms a grout/soil mixture jacket within the disturbed soil along an exterior of the pipe pile assembly which adds appreciably to the overall stability, and particularly the lateral stability, of the pipe pile column created.
A pipe assembly may have one or more pipe segments that are coupled together or coupled to a drive socket by a coupler. The coupler may have a body with a generally tubular shape with an interior surface and an exterior surface. First and second flanges may extend outward from the exterior surface to engage the drive socket, thereby providing enhanced stability and coaxiality. The interior surface may have an upper receiving feature that can receive the bottom end of an overhead pipe segment, and a lower receiving feature that can receive the top end of a subtending pipe segment. The upper receiving feature may have an upper threaded bore with a lead-in portion that facilitates alignment of the overhead pipe segment with the upper threaded bore. The interior surface may also have a stop feature that prevents over-insertion of the top end and/or the bottom end into the coupler.
A pile assembly to be driven into the ground comprises an elongate member, a drive member, and a plurality of flight members. The drive member is supported by the elongate member to facilitate axial rotation of the elongate member. The plurality of flight members is supported by the elongate member. Axial rotation of the elongate member causes the plurality of flight members to auger the elongate member into the ground. The flight members are arranged to balance the loads on the elongate member as the elongate member is driven into the ground.
Apparatus And Methods For The Placement Of Pipe Piling
Apparatus and methods for the installation of pipe pilings into the ground for use as structural building foundations, geothermal piles, or both, are disclosed. In addition to specialized fittings for pipe pile assemblies, the inventions include specialized drive mechanisms used in conjunction with rotary or vibratory motors. Methods of installing pipe pilings are further improved with the disclosure of methods of adding grout or similar materials during or after installation of the piles.
