Sinorock self drilling anchor can solve construction’s problem efficiently
During the constructions of underground works, it is very common to encounter soft rock, fractured zone and large deformation due to high ground stress. In the case of serious collapsing, extra-long anchor is needed instead of ordinary one.
Because of poor rock stability, it’s difficult for drilling machine to form hole. While regular pipe shed is often steel tube with eyelet on its surface, jacking and grouting methods are needed when construction, so it’s difficult to install.Self drilling hollow anchor bar can solve this problem effectively.
Sinorock self-drilling anchor embodies drilling, grouting and anchoring as a whole. Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It’s irreplaceable in narrow construction environment.
Sinorock Self drilling hollow anchor with drill bit can drill hole with common drilling machine. When reaching to designed location, self drilling anchor and drill bit are left in rock body, grouting can be proceeded directly. Unlike pipe shed, self drilling hollow anchor has injected holes on the top of drill bit, slurry is from bottom to eyelet, then diffuses all around to reinforce surrounding rock. Without pulling out hollow anchor bar and drill bit, it has strong adaptation on surrounding rock, even drilling and grouting at loose and broken surrounding rock.
Self drilling hollow anchor in loose surrounding rock tunnel can be used as pipe shed to support in advance, which can solve construction problems of hole-forming and installation.
