SDA_Self Drilling AnchorsOngoing development of faster, safer and more exotic tunnelling techniques places a constant pressure on manufacturers to provide more efficient rock support solutions which will help the shortening of cycle time. As ground conditions get more and more demanding, emphasis is placed on flexible and intelligent support systems in which rock and soil reinforcement is expected to contribute to the productivity and safety of the operation.
The trend has been to provide rock support and reinforcement systems that are easy to install, assure efficiency and providing safety. The self-drilling anchor is today’s answer to the increasing demands of the tunnelling industry and ground engineering for safer and faster production. The system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.
The components of SDA – Self Drilling Anchor System : Hollow Core Bar/Rod , Nut , Anchor Plate , Bit (Sacrificial), Coupler ( where necessary), Simultenous injection adaptors (where necessary), System can be used also as galvanized.
