Jet Grouting

Jet grouting technique consists in injecting cement grout at high pressure. The bi-fluid jetgrouting technique consists in injecting air and cement, and allows to obtain piles with a greater diameter. Tri-fluid injection, consists in injecting simultaneously air, water and cement.

DAT instruments, datalogger for drilling, MWD, jet grouting, soil mixing, deep mixing, CFA, vibroflotation

Display, directly on datalogger LCD, of instantaneous and average recorded parameters, of graphics in terms of depth and of summarizing data.Automatic start of the equipment when starting recording, automatic stop when reaching required depth, automatic management of step time of rod ascent.Automatic recognition of rod changing operation. Automatic recording suspension.Data downloading to PC in order to process, file, export and print exhaustive reports. Measuring and recording of the following parameters (by appropriate sensors, both during drilling and withdrawal rod movement):

  • drill depth (JET DEPTH)
  • feed force (JET FORCE)
  • translation rod speed (JET DEPTH)
  • boring rod rotation torque (JET TORQ)
  • boring rod rotation speed (JET ROT)
  • X and Y mast inclination (JET INCL XY)
  • cement pressure, flow and volume
  • water pressure, flow and volume
  • air pressure
  • rod rise step time
  • injected column length
  • date and time of drilling/jetting and duration
  • soil relative energy
  • input for GPS receiverDAT instruments, dataloggers for Jet grouting - Grouting - Cement injection - TAM grouting - Drilling - MWD - CFA - Deep mixing - Soil mixing - Vibroflotation - Diaphragm walls - Lugeon test - Mineral investigation
