The pressure sensor may be positioned in the base portion of the sonde, with removable sensors connected thereto with a sensor plane at a distal end of the sensors that measures any number of parameters associated with the liquid in which the sonde is immersed. An orientation sensor positioned in the base portion determines an orientation angle of the sonde that, in combination with the depth determined at the pressure sensor location by the pressure sensor, provides the ability to determine the actual depth of the sensor plane, irrespective of orientation angle. Accordingly, improved depth measurement is achieved, without having to confine placement of the pressure sensor at the sensor plane.

  • Publication number: 20150117960
    Abstract: 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.

  • Publication number: 20150027785
    Abstract: A borehole reaming cutter retention and fastening/locking system enable field replacement of borehole reaming cutter assemblies utilized in infrastructure emplacement horizontal drilling (HDD) applications. The borehole reaming cutter assembly retention/fastening system can withstand borehole drilling forces without the necessity of permanent welding, thereby allowing cutter interchangeability/replacement in the field. The borehole cutter retention assembly shape and design, coupled with the fastening/locking mechanism design, may be robust enough to replace permanent welding and may allow field cutter interchangeability and replacement. Current designs and devices utilize permanent welding of component/cutter assemblies, thereby requiring workshop/welding construction and deconstruction to enable the interchangeability and replacement of cutter assemblies.
