Melbourne Metro project: a showcase of Dextra solutions
The Metro Tunnel is a major enhancement to Melbourne’s rail network, a multibillion-dollar project comprising the design and construction of twin nine-kilometer tunnels and five underground stations.
The stations are designed based on the architectural character of the local area.
Dextra has been selected as a one-stop solution supplier, thanks to its wide range of products.
The numbers are impressive:
- 400,000 Griptec rebar couplers
- 5,300 GFRP Combination Bolts
- 900 GFRP soil nails
- 16 软眼
Dextra was able to support and share their expertise on GFRP at design stage and produce the GFRP solutions as per the owner expectation.
Coupler performance tests at elevated temperatures
The Imperial College London tested Dextra Bartec/Fortec and Griptec couplers at elevated temperatures to evaluate how the couplers would perform in case of a fire.
测试的亮点包括：
- The findings indicate that current codified rules can be used for assessing the strength and stiffness properties of both non-spliced rebar and rebar connected with Bartec/Fortec or Griptec couplers.
- At temperatures below 400°C the ultimate tensile strength and stiffness of Bartec/Fortec and Griptec splices, as well as un-spliced rebar is not significantly affected.
- When tensile tested at temperatures below 500°C, failure still generally occurred in the rebar outside of the Bartec/Fortec or Griptec coupler region.
