Initial and Final Shotcrete Linings for Edouard Montpetit Station of REM Project – 2024 Honorable Mention Project
R.seau Express M.tropolitain (REM) is an automated (driverless) light-rail transit (LRT) system in Montreal, Canada. It features 67 km (42 mi) of double tracks and 26 stations. Once completed, it will be the 4th longest automated LRT transportation system in the world.
Anderson Dam Tunnel – 2024 Outstanding Underground Project
Drill Tech Drilling & Shoring, Inc. performed Sequential Excavation Method (SEM) tunnel construction with geometric cross sections consisting of 19 ft to 24 ft (5.6 to 7.3 m) diameter tunnels (including wide span intersections) for the Anderson Dam Tunnel Project.
Relieving Water Pressure on Shotcrete Lining by Integrating a Drainage Mesh
Underground construction, especially a tunnel, is one of the most complex challenges in the field of civil engineering. Dolenco Drain is an innovative solution which addresses many of the difficulties with controlling or eliminating water pressure in an easy, safe, long-term, and cost-effective manner.
Early Age Strength Testing for Shotcrete: 2024
For improved safety in tunneling and mining projects that use shotcrete for ground support, early shotcrete strength should be evaluated by testing. Based on their range of effectiveness, two procedures stand out: The new Hilti BX 3-SCT stud driving method and the beam end tester.
The Application of Shotcrete in Shafts: Work Preparation and Construction Based on Various Projects in Central Europe
Shotcrete shafts often present unique challenges for construction projects. In many cases the construction method is different from the one used in the main tunnel (often using a TBM), presenting challenges recruiting experienced and certified personnel for the shaft works.
Polymer Rubber Gel Technology: High-Performance Waterproofing for Shotcrete and Blind-Side Applications
The innovative GTS Polymer Rubber Gel waterproofing systems are proven and effective for underground construction applications.
Summary of ‘Guideline on the Applicability of Fiber-Reinforced Shotcrete for Ground Support in Mines’
This guide examines and provides a description of the common testing methods used for FRS and how to interpret the information generated for ground support in mines.
Updated Fiber-reinforced Shotcrete Testing Standard — Faster, Easier and Better!
The updated fiber-reinforced shotcrete testing standard in underground projects provides not just significant cost savings, but just as critical, helps us to significantly reduce the carbon impact of the underground construction industry and provide for a better environment and future for us all.
The Rondout Bypass Tunnel Shafts – Shotcrete Lining
The Rondout-West Branch Tunnel (RWBT), a segment of the Delaware Aqueduct (the Aqueduct), was built from 1937 to 1944 and provides about 50% of New York City’s total water supply. The tunnel is concrete lined and has a finished inside diameter of 13.5 ft (4.1 m). It is about 45 mi (72 km) in length and runs in the southeasterly direction from the Rondout to the West Branch Reservoirs.
