TXI and AXI Barriers (Bafu* Approved 100 kJ to 500 kJ barriers)

The TXI and AXI Barriers without retaining ropes are designed for low-energy rock-fall protection. They are approved according to the guidelines of the Swiss Federal Office for the Environment (BAFU). Tests on the TXI Barriers show that the barriers are only minimally deflected with a maximum event and maintained a residual useful height of 85% in the impact zone. Thanks to a logically planned overall construction with lightweight parts and easily installed individual components, TXI rockfall barriers can be installed with a minimal outlay of man-hours and cost.

The AXI rockfall barriers were developed for protective structures adjacent to (service) roads: They have reinforced posts which do away with the need for retaining ropes. The rigid AXI systems are also suitable for supporting walls, existing concrete structures or compacted rock faces to which they can be simply mounted and anchored.

RXI Barriers (Bafu Approved) 250 kJ to 5000 kJ barriers)

Geobrugg supplies RXI rockfall protection barriers approved according to the guidelines of the Swiss Federal Office for the Environment (BAFU) for absorption capacities of 250 kJ (low energy), 500 kJ, 1000 kJ, 1500 kJ and 2000 kJ also for 3000 kJ and 5000 kJ (high energy). They are characterised by large residual heights in the impact field, no deflection with maximum event and the ability to maintain functional serviceability with combined stresses such as multiple hits, tree falls and snowslides.

Central to the RXI concept is the ROCCO® ring. In the case of an event the energy is first dissipated through the plastic deformation of the ring bundle. This reduces the stress on the anchors. RUNTOP® running ropes allow the ring net which is fixed to shackles to slide in a matter of split seconds to the place they are most needed - known as the curtain effect. The components are:

• Ground plates with linked post fixing
• Spiral rope anchors or self-drilling anchors with Geobrugg FLEX head
• Supporting and retaining ropes, guided by brake rings

GBE Series Barriers (Etag Approval 500 kJ to 3000 kJ)

The new GBE rockfall protection barriers are supplied for impact energies of 500 kJ, 1000 kJ, 2000 kJ and 3000 kJ and have been successfully tested and approved under vertical fall conditions according to the guideline ETAG 27.

Mounting is amazingly quick and simple. The mutually adapted components are quick and simple to install. The high-tensile TECCO® or the SPIDER® spiral rope net can be delivered to the site pre-assembled to the posts, where they are drawn over the supporting rope like a drape.

GBE barriers satisfy the stringent requirements of ETAG 027 category A.

Our GBE rockfall protection barriers have a verified residual useful height corresponding to the highest category A of ETAG 27: After the test at 100% of the nominal energy, we verified a residual useful height of over 50% of the original construction height. The European Technical Approval (ETA) was issued by a recognized licensing authority. This allows the product to carry the CE mark which in a few years will become obligatory in all European countries.
