The Installation of Sinorock Self-drilling Anchor Bar
Sinorock self drilling anchor bar sets drilling,grouting, anchoring functions in one.
It is suitable for a variety of environments.Here are the two conditions of
the anchor bolt installation.
1.For the bigger cover thickness and less gravel layer,using sinorock self drilling
anchor bar is appropriate to use cyclotrondrilling method with the anchoring
bar and it also can guarantee the engineering quality.
2.For the seriously weathering rocks,using DTH drilling method drills borehole
whose aperture isΦWhen the drill bit pull out from the second borehole,it is
usually collapsed.Then using the sinorock self drilling anchor bar drill again,
it solves the problem of not deep even we drilling once more.On the other hand,
it can also smoothly install the sinorock self drilling anchor bar in that condition.
According to the method of construction,sinorock self drilling anchor bar
can cope with various complex conditions.Meanwhile,the construction quality
and the period can be guaranteed.
