Application of Pile-Cutting Technology Suiting Different Tide Levels in A Dock Project in East Africa
The penetration degree serves as a parameter to stop tamping steel pipe pile with hammer,thus the top elevation of pile is often inconsistent with the design elevation,which requires pile-cutting process.The traditional offshore pile-cutting is greatly affected by tide level.Due to limited working time,10～15 piles can be cut by a team with a special crane per day,which means lower mechanical efficiency.Relatively less daily working time corresponds to the area with heavy stormy waves.A floating row suiting different tide levels is designed in a dock project in East Africa.A hoist is used to lift the floating row above water surface,which prevents stormy waves from the steel pipe piles being manually cut up to the connection in a few centimeters.40～50 piles can be cut by a crane a day subject to the operation in a whole area.The above process greatly improves pile cutting efficiency,reduces number of mechanical shifts,and provides a reference for the docks supported on steel pipe piles.
