Wassara is launching a new way of drilling for instrumentation casing in dams
Jul 18, 2014
Wassara has developed a completely new system for installation of monitoring instrument in dams. A 40 mm tube can now be installed in two hours instead of the two days required by traditional technologies.
By combining Wassaras DTH technology with a filter tube, installing instruments can be carried out much faster than with traditional methods. A traditional installation of a 40 mm tube usually requires up to two full working days. A Wassara installation of a 40 mm tube takes approximately two hours. This is up to eight times faster than comparable technologies.
The system comprises a Wassara hammer with 43 mm bit, filter tubes, drill rods (Ø 40mm), inner tube and an extractor tool to retrieve the inner tube after installation. The smallest internal diameter is 26 mm (the filter tube).
