  • Publication number: 20130294843
    Abstract: 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 associate with a support portion of the auger. Such a support portion defines a proximal section of the helical structure, which has an extension substantially centred 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; ?-?) that is not aligned relative to the longitudinal axis (X-X).

  • Patent number: 8506207
    Abstract: A helical screw pile includes a longitudinal shaft having a top end and a bottom end with a plurality of helical plates arranged on the shaft in increasing diameter from the top to the bottom. The first helical plate is located toward the bottom of the shaft and has the largest diameter. The second helical plate is located above the first helical plate and has a diameter smaller than that of the first plate. The third helical plate is located above the second helical plate and has a diameter smaller than that of the second plate. The helical plate with the smallest diameter is located toward the top of the shaft. The distance between the first helical plate and the second helical plate is larger than the distance between the second helical plate and the third helical plate.

  • Publication number: 20130168154
    Abstract: A horizontal directional drilling sonde housing has a cavity for receiving a sonde. Signal channels extend from the cavity to an exterior of the housing. A polymer lines at least part of the cavity and fills the signal channels. The drilling tool has a bit body and a drilling body. The two bodies have respective lateral surfaces which engage each other to prevent the transverse movement of the drilling body relative to the bit body during operations. The drill bit has a forward extending drill tooth, which drill tooth is removable from a bore. A spacer is located in the bore between the bottom end of the bore and the tooth. The drilling bit has buttons located on the side in a spiral configuration about a longitudinal axis of the bit.

  • Patent number: 8443918
    Abstract: Excavation equipment for the construction of compaction piles includes a tool mounted at the end of a drilling rod; the tool is constituted by a shaft (10) provided on its end with digging teeth (12) and with at least a plate (14) for collecting debris rotating between an open position during the excavation and closed during the ascent of the tool. A screw (17, 18, 17?, 18?, 20); is of the type having at least two principles (17, 18, 20), in the upper part (20) fixed directly on the shaft (10) and in the lower part (17, 18) fixed on a cylindrical element (16) inserted on the shaft. A compactor (19) is positioned on the screw (17, 18) of the cylindrical element (16). The shaft rotates between two positions displaced between them, one corresponding to the excavation condition and the other to the ascent one; each of the at least two-principle screws of the shaft (20) constitutes the continuation of a corresponding screw (17, 18) of the cylindrical body (16) depending on the angular position of the shaft (10).

  • Patent number: 8418784
    Abstract: In one aspect of the invention, a drilling assembly comprises a head located on a rotational axis of the assembly and comprises at least one head element. At least one blade extends distally from the head. A plurality of blade degradation elements are rotationally supported on the blade. Each degradation element comprises an attack angle that affects the penetration rate of each degradation element and a laterally offset angle that primarily affects the rotational rate of each degradation element within their holders. The drilling assembly comprises a central cutting region. The blade degradation elements within the central cutting region form an attack angle of 15 to 20 degrees with the rotational axis of the drilling assembly.

  • Patent number: 8381843
    Abstract: A well bore reamer has an elongated body for coupling between members of a well string, a first set of cutting elements on the body at a fixed position, a second set of cutting elements on a sleeve closing around a sleeve carrying portion of the elongated body. The sleeve is slidable along a longitudinal axis of the body and rotatable thereabout. A lower clutch mechanism operates between the sleeve and the elongated body at a bottom end of the body's sleeve carrying portion to block rotation of the sleeve relative to the elongated body in a predetermined direction about the longitudinal axis under sliding of the sleeve into a lowered position adjacent said bottom end of the sleeve carrying portion.
