The main elements of the system are self drilling anchors, reinforced shotcrete surface cover and subhorizontal drains.The length and spacing of the self drilling anchors are variable depending on the depth of the excavation, environmental loads and soil conditions, etc.
In this self drilling anchor system, depending on the ground conditions after each excavation stage pre-shotconcrete is applied, followed by passive anchor drilling. Appropriate reinforcement is placed into the drill holes according to the design and the drill hole around the reinforcement is grouted with cement grout.

Besides tunneling,mining,slope foundation,civil construction,
Sinorock's high quality self drilling anchor systems also work to stabilise foundations and support structures for excavation, making worksites safer. We work closely with geotechnical engineers to assist with project design and selection of anchor type after consideration of ground conditions, ensuring lasting integrity of all our self drilling anchor systems.
