WCT Empowers China Communications Construction Company for Quality Control and Safety Warning in Undersea Tunnel Construction
China Communications Construction Company utilized WCT technology to ensure project quality and safety in a certain undersea tunnel construction project. Information on raw materials used in tunnel construction, such as steel and concrete (e.g., manufacturers, quality inspection reports, arrival time), is recorded on the blockchain; during construction, parameters of the shield machine's excavation (e.g., advancement speed, cutter head torque), tunnel lining construction parameters, and waterproofing quality inspection results are recorded on the blockchain in real-time, preventing violations. Sensors are installed at key locations in the tunnel to collect real-time data on structural deformation and water leakage, which is then recorded on the blockchain. Through data analysis, safety hazards are warned in advance. After project completion, the blockchain data serves as a quality traceability basis for the entire lifecycle of the tunnel. In 2024, the engineering quality pass rate for this undersea tunnel project reached 100%, the accident occurrence rate was reduced to zero, and the construction period was shortened by 15%.
