At present, a pile stabilization platform is usually used to control the pile sinking accuracy of the jacket foundation.

First, sink the center positioning pile, then insert the platform body into the center positioning pile through the center positioning pile sleeve, and float on the sea surface with the help of the buoyancy box at the bottom of the platform. Then insert the auxiliary piles into the auxiliary pile limiting guide holes. After the auxiliary piles are sunk, weld the platform body and the auxiliary piles so that the platform body is built above the sea surface. Finally, insert the steel pipe piles of the conductor frame foundation into the steel pipe pile limiting guide dragon mouth.
