Precise concrete distribution during the construction of the Three Gorges Dam

During the construction of the world's largest dam, reliable and precise control of concrete distribution across a 3 km wide dam wall was essential. Standard radio solutions reached their limits - but with the DATAEAGLE 2320, interference-free, high-performance radio communication was guaranteed. Find out how this technology enabled the smooth transportation of materials in one of the largest construction projects in history!

Application

During the construction of the Three Gorges Dam in China - the largest dam in the world - concrete had to be precisely transported and distributed across a 3 km wide dam wall. Siemens supplied the electrical engineering for the concrete distribution systems.

Challenges

The concrete cranes transport the concrete using a trolley and must reliably open and close the concrete buckets at the right points. An interference-free radio system with a long range had to be used, as conventional Bluetooth solutions were not sufficient.

Solution

The DATAEAGLE 2320 with 500 mW transmission power was used, which operates via proprietary radio technology in the 869 MHz band. The system transmits switching signals via relays, automatically calculates the position of the concrete bucket and enables precise control in automatic mode.

Products used

  • PROFIBUS radio data transmission system
  • Radio module DATAEAGLE 3712

Outcome

Thanks to the high reliability and robustness of the DATAEAGLE 2000, the multi-year construction of the dam ran smoothly. The precise control of the concrete distribution contributed to the efficiency and safety of the construction project.
