Sinorock produces a range of standard and high capacity self drilling rock bolt

It is obvious that theself-drilling rock anchorhas the advantage that ordinary anchors do not have, and it is common practice to apply bushings to the weathered rock, gravel, clay, sand, pebble, etc. To prevent collapse, with a self-drilling rock anchor can save the casing, the water-cement ratio of 0. 4 -0 7 pure cement slurry (non-clay formations) to consolidate the pore walls to prevent collapsing at the same time when drilling. The biggest advantage of the self-drilling anchor is the completion of drilling, anchoring and grouting in one process, simplifying the construction process, saving at least 25% of the workload, greatly shortening the duration, in order to achieve the goal of reducing engineering costs. Self-drilling rock anchor can effectively replace the general steel bar and part of the prestressed anchor cable, it is a reliable new technology of rock and soil anchorage, with a wide range of applications, and it can promote the rock and soil materials production technology sets, factories standardization, which is conducive to improving the quality of the project.

Sinorock produces a range of standard and high capacityself drilling rock boltsuited for various uses including: micropiles, tension rods, nailing, slope stabilization, etc.

Sinorock self drilling rock boltoffers an excellent choice for micro piles in difficult ground conditions where open-hole drilling isn’t possible. The continuously threaded bar profile lends itself perfectly for restricted headroom applications because the bar can be cut and coupled at any length.
