DYWI ® DRILL SYSTEM
DYWI ® Drill System
System DescriptionThe DYWI ® Drill System is a fully threaded steel bar which can be drilled and grouted into loose or collapsing soils without a casing. The bar features a
hollow bore for simultaneous drilling and grouting and a left-hand rope thread for connection to standard drill tooling.
Manufactured from heavy wall steel tubing to EN 10083-1, DYWI ® Drill Hollow Bar is cold rolled to form a standard rope thread profile (R25-R51). The rolling process refines the grain structure of the steel, increasing the yield strength and producing a durable drill rod suitable for a range of applications.
DSI Injection Anchors can be installed into a variety of different soils and ground conditions ranging from sand and gravel to inconsistent fill, boulders, rubble and weathered rock, as well as through footings and base slabs.
Key features of the DYWI ® Drill System are:
Simultaneous Drill and Grout Installation
Combines both operations into a single construction cycle, enabling high rates of production.
Fully Threaded Rod Sections
Continuous thread ensures that rods can be cut and coupled at any point.
No Casing Required
Can be installed into loose or collapsing soils without the need for a temporary casing to support the borehole.
Rotary Percussive Drilling
Enables quick rates of installation, good directional stability and assists in the consolidation of the grout within the borehole.
Rope Thread Profile
Standard ISO rope thread (R25 - R51) produces an excellent bond between the bar and grout, and enables connection to conventional drill tooling.
Self-Drilling Injection Anchor
Suitable for a range of applications, including: Soil Nails, Micro Piles, Ground Anchors for temporary works, Rock Bolts and Spiles.
