采用灌注桩双护筒工艺穿过海底 抛石斜坡的应用研究.

During the construction of the deep drainage project for the new works for Shenhua Luoyuan Bay Power Plant in Fujian Province, the construction of offshore cast-in-place piles was seriously impacted due to the bad geological conditions as the construction area was located in the riprapped slope of the jetty, easily causing the slipping of the slope. The boreholes for cast -in -place pile construction cannot be made with the conventional method. The paper describes how the construction of cast -in -place piles on the riprapped slope was completed by using the double casing technology and presents effective measures to control the slipping of the casing and the leakage of slurry during boreholing.
