The excavation safety of underground dependence is determined by the rate and correctness of the support system used. Argentium presents its innovative Water Water Expandable Rock Bolts, a revolution in geotechnical engineering, which is a new style to provide urgent load-carrying capacity in the most challenging rocky masses. The space unlike the traditional grouted bolts, which require hours of settling, our expandable system employs the use of high pressure water injection to achieve a mechanical interlock between the bolt and the borehole, thus holding on to the workspace within seconds of installation.
Being durable and user-friendly, the Argentium rock bolts are a preference in the modern mining, tunnelling and civil engineering works. This is because, by eliminating the need to use resin or cement grout, we significantly reduce environmental footprint and also cleanup of the site, as well as, timing of projects. And in the case of fractured rock, seismic activity, or high-stress conditions, Argentium can offer a strong, flexible and permanent support, which is geometricalally modified to match the specifics of each borehole.
Argentium Expandable Support has 4 Pillars:
- Immediate Full-Column Anchoring: The bolt widens in all directions, following the dissimilarities of the borehole. This creates a powerful frictional bond and mechanical interlock that provides complete load bearing ability immediately and allows the excavation face to immediately advance.
- Grout Free Installation: We do not use chemical resins and cement because we only use high pressure water to expand it. This leads to a more clean working environment, no chemical discharges and an easier supply chain hence lowering the cost and complexity.
- Extraordinary Versatility and Flexibility: Our bolts have been designed to suit changes in borehole diameter and shape. They are also excellent in both soft rocks and fractured zones as well as hard rocks, taking up the deformations of rock and controlling seismic energy due to their internal makeup of ductility.
- Quality-Assured Installation The process of installation has inbuilt quality control. The expansion pump will release the bolt when the required pressure is met and this gives the engineers and the operators the visual and mechanical assurance that the bolt is properly fixed and tight.
