The project will adopt domestically made equipment to recycle the polluted oil and silt to abstract the residual oil and have it refined into crude for sale.
The soft riverbed filled with silt and sand also made the construction challenging as it had higher requirements for stability.
This meant cutting open the "belly" of the lake with a large-section structure to prevent any water leakage and conducting ant-like transport of lake earth and silt to exterior regions in large quantities.
The river banks were all covered with bushes and silt.
You could barely see the river because it was all covered with bushes and silt.
Measuring 130 meters long and weighing 4,800 metric tons, the slurry TBM, with a maximum thrust of 25,000 tons, can cope with complex terrains such as soft silt and hard granite bedrock, according to its manufacturer the China Railway Engineering Equipment Group Co Ltd (CREG), one of the leading TBM suppliers worldwide.
But 5G robots can accomplish the task in about 20 days as they obviate the need to pump out water from the stilling basin, besides doing some basic work like removing silt.
And with the advantage of the 5G network's large bandwidth, the high-definition images collected by underwater robots can be transmitted back to a control center in real time and the staff can remotely control the robots to do some basic work such as removing silt.
