Abstract: Tuotuo River Pumping Station on Gela Oil Transport Pipeline lies near the bank of Tuotuo River. As the sand soil bank couldn't stand with the scour of the flood, the safety of the pumping station was in danger. To protect the station site, bank protection had to be carried out. Rubble masonry dyke would be damaged by freeze under local climate condition; flexible rock crib dyke could stand with frost heave and scour, and it was a reliable protection measure. Introduced the role of the rock crib dyke, concrete design and construction method.
