The proven section technology of the Bochumer Eisenhütte and our many years of mining experience are also applied in tunnelling. At the beginning of the 1980s, lattice girders found their way into modern tunnel construction. Today, in addition to the TH and mine support sections, they significantly contribute to mining and tunnelling innovation, together with shotcrete.
As a systematic supplement to our TH support segments and lattice arches, we offer our national and international customers a range of rock bolts tailored to their mining, tunnelling, and general construction needs. They are additionally suited for special civil engineering. The rock bolts comply with the DIN EN 21 521 standards.
Our range of rockbolts and accessories includes:
- Rock bolt based on threaded steel as an adhesive anchor
- Reinforced concrete anchors
- Expansion anchor
- Friction bold
- Injection-drill anchor
- SN Anchor
- Load anchor for transferring static and dynamic transport stresses as in overhead monorail operation
- Self-drilling tube spile
- Accessories via anchor plates, connection sockets, load step indicators
- Galvanisation according to specifications
- On-site consulting
With the lattice girder system “Starke Welle” [Strong Wave], the Bochumer Eisenhütte has developed a supporting arch that has established itself worldwide in the construction of subways, caverns, canals, railway tunnels, and road tunnels. Our company developed the technical concept of today’s lattice girder systems in addition to the TH profile – a patented BE innovation. Our know-how spans from individual consulting and design to the development of alternative solutions, if necessary.
