Pilot Project Uses Steel Fiber-Reinforced Tubbings in Construction of U5

  • Posted on

During construction of the new underground U5 line in Hamburg, Germany, U5 GmbH will use steel fiber-reinforced concrete segments in tunnel construction for the first time in Germany, marking a major milestone for the project. These prefabricated concrete components, used to line and stabilize tunnels, reduce traditional steel reinforcement by replacing steel bars with finely distributed steel fibers within the concrete. U5 has received an “approval in individual cases” from the technical supervisory authority for the application. As a result, the joint venture between ZÜBLIN and Wayss & Freytag will be able to install the reduced-steel tubbings in the machine-excavated […]

Patent-Pending Tech May Help Prevent Hazardous Underground Utility Strikes

  • Posted on

The Common Ground Alliance estimated in 2019 that the annual total social costs of underground infrastructure damage in the United States reached approximately $30 billion. With that in mind, Purdue University engineers have developed a patent-pending method to decrease hazardous strikes to underground utility pipes during construction projects. Engineers are improving upon traditional ground-penetrating radar data to better estimate the location, orientation and radius of underground utility pipes with new technology that could lower related financial losses, service disruptions, injuries and fatalities. The research uses a Bayesian framework to quantify uncertainty in estimating underground pipe depth, horizontal position, orientation and […]
