Application of T thread self drilling anchor bar
Time:2022-06-02 17:05:03From:This Site

Hollow steel tendons with the SINODRILLS T thread are used when the bond behavior is critical for the level of safety required. The advantage of the self drilling system (SDA / IBO) system are:



 Variable applications


No stalling when drilling across clefts Dynamic grouting during drilling


Simple to install in unstable boreholes


Drilling and installation in one operation No need to extract drill strings


Especially advantageous in rocks / soils with low cohesion



Grouting assured over full depth of borehole



Stabilization of the borehole with cement slurry
