Research purposes: The construction problems of bearing platforms with high piles were solved under hydrology and geology conditions of uncovered riverbed,hard and inclined rock surface,corrosion,deep water.This could serve as a useful reference for future construction of similar kinds of bearing platforms.Research methods:By construction of bearing platforms with high piles for the Sanmenjiang bridge in Liuzhou city,this paper introduces design and construction of steel hoisting box cofferdams with pull and compression columns,and puts emphases on design scheme,working principle,construction technology,construction gist of steel hoisting box cofferdams.The problems which may be paid attention to in steel hoisting box cofferdams construction are expatiated.Research conclusions:This paper sums up a suit of steel hoisting box construction technology under geology conditions of deep water,uncovered rock and corrosion.The design of this steel hoisting box with pull and compression columns was reasonable and could satisfy the requirement of engineering.
