Continuous monitoring of drill head parameters at pilot drilling is fundamental to horizontal drilling technology. Control can be achieved with Radiodetection’s state-of-the-art detection system RD385, which includes the following:
A compact portable receiver, RD385L, with parameter calibration, control and display systems.
A remote monitor, RD385 DataView, installed at the drilling rig operator’s workplace.
Sondes installed in drill heads to transmit drilling data.
The sonde transmits data on drill head roll, tilt angle, depth, position, sonde battery charge levels and temperature to the RD385L receiver in the operator’s hands. The receiver has different modes that enable its use as a standard detector for cables and pipes detection.
The 50-Hz detection mode is used when searching for conducting cables. In the passive radio mode (14-26 kHz), the receiver gets signals from radio transmitting equipment on cables or pipelines.
Operations with generators can be conducted in two modes: detection by induction (with two induction frequencies, 8 kHz and 33 kHz) and direct connection of a generator with a traceable line. Radiodetection’s recommended generator is RD4000 T10 or Genny+.
The RD385 DataView Remote Monitor displays the data (on roll, tilt angle, and depth) that RD385L receives. The monitor is installed on a drilling machine to provide convenient steering control. It displays the same data as the receiver, and can obtain information from a receiver up to 250 meters away. The remote display unit shows data on the angles of longitudinal and lateral tilt, transmitter temperature and accumulator battery conditions.
The RD385 DataSonde is installed in drill heads and can measure roll, tilt angles, temperature and battery charge levels.
