SAS anchor systems for mining and tunnelling application.
SAS anchor systems are used in various ways in mining and tunnelling constructions and serve to optimize traffic routes or mine raw materials. Dependent on the construction system used, geology of the surrounding rock and hydrological conditions underground, we offer a variety of anchor systems to meet specific project requirements.
SAS permanent anchor system used for soil stabilization systems. Anchors are devices which introduce forces through the pre-stressed components into the ground. The function of the pre-stressed anchors is to prevent stretch deformations caused by occurring loads and to provide safety by transferring the forces into the grouted body, which transfers the load into the stable building ground.
SAS anchor systems are available using thread bars in the grades SAS 450/700, SAS 500/550 (with DIBT approval), SAS 650/800, SAS 670/800 and as smooth bars, grade E 360/690-830. The wide range of steel grades ensures technic and economic optimized construction systems.
SAS anchor systems such as the SAS expansion shell anchor or SAS resin anchor systems are either individually assembled or supplied as preassembled anchor systems. SAS anchor systems effectively improve the stability of underground rock masses. The increased load-bearing capacity of the rock conditions enables an early construction start, thus providing both technical and economic advantages.
For soil stabilization the SAS Rock bolt system and the SAS Hollow bar system are used. Hollow bar nails consist of three main components: the nail head, the steel tendon (including coupler and single-use drill bit) and the grout body. The steel tendon is a hollow steel bar with a cold rolled round thread and can therefore be cut or joined at any desired point.
Thanks to our systems’ flexible application options, our customers can choose next to mechanical and chemical anchors and bolts from a variety of anchoring systems, e.g. eyebolt anchors, hook anchors and additional roof support structures, which are all custom-tailored to satisfy individual project requirements.
