Geotechnical investigation and testing - Field testing - Part 15: Measuring while drilling (ISO/DIS 22476-15:2015)
|ICS Code (Earthworks. Excavations. Foundation construction. Underground works):||93.020|
This standard specifies the technical principles for measuring equipment requirements, the execution and reporting on the parameters of investigation drilling process for geotechnical purposes. The measuring while drilling (MWD) method deals with the recording of the machine parameters during the drilling process. This can be done manually or with the use of computerized systems which monitor a series of sensors installed on rotary and/or percussive drilling equipment. These sensors continuously and automatically collect data on all aspects of drilling, in real time, without interfering with the drilling progress. The data are displayed in realtime and are also recorded for further analysis.
