    摘要： The helical drill bit defines a helical end section of a helical structure formed at its periphery by an auger of an excavation assembly, and it is associated or associable with a support portion of the auger. Such a support portion defines a proximal section of the helical structure, which has an extension substantially centered around a longitudinal axis (X-X). The helical drill bit is adapted to rotate about the longitudinal axis (X-X) together with the support portion so as to drill a hole in the ground. The helical end section extends around an extremity axis (Y-Y; Ψ-Ψ) that is not aligned relative to the longitudinal axis (X-X).

    摘要： A method and apparatus for driving a pile are disclosed. The pile-driving apparatus comprises a pile, a shoe tip coupled to a toe of the pile, and a drill string disposed within the pile. The drill string comprises a gripping device coupling the drill string to the pile and a hammer deployed into the pile such that the hammer is capable of transmitting a force to the shoe tip. The method, comprises positioning a hammer in a pile such that the hammer is capable of transmitting a force to a shoe tip; positioning, in the pile, a portion of drill pipe having a gripping device to engage the pile; and deploying the pile beneath the surface of a body of water.

    摘要： The present invention relates to a method and an apparatus for a loading test of a pile using a self-repulsive force. The loading test is separately performed in two stages, a first stage to estimate the ultimate peripheral skin friction force and a second stage to estimate the ultimate tip end bearing capacity. The loading test apparatus of the present invention has simple construction capable of reusing, which results in carrying out the loading test with ease and in cost effective manner.

    摘要： Expandable tubular mandrels have lengthwise sections the upper ends of which are joined by a head. Hydraulically operated piston-cylinder units within the mandrel are spaced apart lengthwise of the sections and connected to the mandrel in a manner such that the axis of each unit extends lengthwise of the mandrel and expanding and contracting forces are applied to the mandrel sections when the units are operated to vary their overall length, to effect mandrel expansion when their overall lengths are changed in one direction and mandrel retraction when changed in the opposite direction.
