The technology for construction of steel tubular pile caps is described in the this paper.
When installing steel tubular piles in regions where granite is shallowly overburdened, the piles are easy to deviate and the pile tip is easy to warp, resulting in slow driving.
These problems are discussed in the light of the construction of the steel tubular pile foundations for Bahekou Heavy Cargo Wharf in the Three Gorges and Yangjiawan Container &General Cargo Wharf.
