Key Technology of Rubble Base Leveling in Offshore Deepwater Port

For the problems of underwater riprap rubble bed leveling work caused by the offshore deepwater port,Through the domestic and overseas surveys,using model test,land-based prototype test,trial test,and water measurement test,the deep water rubble base leveling ship was developed,the researches on the new technology of riprap,new method to accurately measure the elevation of the fixed point under water,and the deepwater mechanization leveling method were carried out,the overall objectives for integrating the ripped-rock,leveling,and detection and the mechanized leveling are become true.
