Sinorock self drilling anchors can applied in various strata

Self drilling anchors are high strength hollow steel all thread bars which is used as grout injecting, self- grouting soil nail installed as drill rods with a sacrificial bit. These method of installation solves the problem of hole stability in loose overburden soils. Using conventional drill and grout installation methods it provides for unit pull-out capacities. They are lower in cost than the conventional bar system. Fiber- reinforced composite soil nails which is used in the tunnelling industry in which the excavation occurs through the reinforced soil mass. The weight of the shotcrete wall limits the use of this type of materials to temporary walls due to the poor shear capacity.
Sinorock self drilling anchor bars as a reliable and efficient construction method which are most used in applications around the world.
Sinorock self drilling anchor bar is suitable for all the strata that retaining wall and soil nail wall and also the prestressed cable bolt can apply to.
