摘要
Abstract
In the construction of steel casings in a deep-water steep-bare-rock area,steel casings is hard to be driven into rock by the adverse factors such as deep water,high fluctuation of water level,steep bank slope and high rock strength.Based on an anchorage project in the Three Gorges Reservoir Area,a drilling cylinder with screw rod was developed through the study on the design and construction technology of steel casing,An innovative construction plan was proposed,namely,leveling the rock surface at pile position,reaming and drilling by stages,pouring concrete first and then driving piles.The results showed that the proposal was a solution to the problem of driving steel casings into deep-water steep-bare-rock,ensured the construction quality,served as a basis and a reference for similar structure design and construction in the future.关键词
