85mm Inclinometer Casing

The HMA Geotechnical 85mm Inclinometer Casing is used as access tubing for the Model 7000 Inclinometer Probe. Application Used in conjunction with the Model 7000 Inclinometer Probe to measure displacements and inclination associated with slip planes, landslide, slope stability, dam walls, pilings and other large-scale excavations. FEATURES Compatible with all standard inclinometer probes Self-aligning and snap/glue coupling Flexible, impact resistant ABS plastic Accurately machined grooves Quick and simple assembly Flush coupled 85mm for greater shear capacity OPERATING PRINCIPLE The HMA Geotechnical Inclinometer casing functions primarily as an accurate guide for the Model 7000 Inclinometer Probe. The Inclinometer Casing consists of four equally spaced, precision machined internal grooves, which guide the inclinometer probe along the length of the borehole. When ground movement occurs, the casing is also displaced. Traversing the probe along its length reveals changes in its profile. The rate, depth and extent of these changes are calculated by comparing current readings to initial readings.

Borehole Camera - R-Cam TLE Level Wind

Recently designed for 2019, HMA Geotechnical is pleased to present the most up to date Laval Underground Surveys R-CAM, the R-CAM TLE Level Wind. Intended to build on the flexibility and transportability of the R-CAM camera framework, the R-CAM TLE Level Wind includes a large group of highlights not found on the standard R-CAM XLT winch, beginning with the incorporation of a level wind. The R-CAM TLE's level wind has been intended to give a higher degree of cable management that allows the operator to focus solely on conducting video surveys. The R-CAM TLE likewise includes a high resolution, 100 pulse encoder that has been repositioned to vastly increase counter accuracy and allow for a variety of in-field setups such as the use of a tripod. To expand the dimension of versatility of the R-CAM TLE, the extendable boom arm and winch handle can now be totally removed to help in transporting, mounting, dispatching, or putting away the system. Moreover, a battery compartment has been added to give a helpful area to store the 12-volt battery. The R-CAM TLE Level Wind is available as an upgrade for both new and existing R-CAM camera systems. The winch comes equipped with either 1,000 feet (304.8 m) or 1,300 feet (396.24 m) of coaxial, Kevlar reinforced cable.

RST Instruments Borehole Packers are pneumatically or hydraulically inflatable packers that incorporate one fixed and one sliding head attached to a center shaft. This sliding head allows the packer gland to retract about the center shaft as it inflates. The packer heads are constructed of either plated steel or aluminum while the shaft is polished stainless steel or aluminum. The packer gland consists of a rubber membrane reinforced with either polyester fabric or steel. Packers made from steel heads, stainless steel shaft and a steel reinforced gland are suitable for medium pressure applications, while packers made from aluminum heads, aluminum shaft and a polyester reinforced gland are suitable for low pressure applications. APPLICATIONS Permeability testing Hydro-fracturing of formations Monitor well sampling Sealing artesian flows in open or cased boreholes Packer piezometers Pressure grouting QUICK SPECS Steel reinforced, or fabric reinforced, abrasion resistant glands that are easily replaced in the field. Hollow center shaft for placement of sampling and monitoring equipment, or for passing water through the packer during permeability testing or hydrofracturing. RST packers are suitable for a wide variety of applications in open or cased holes. Optional sealed instrument and/or pump pass through.
