钻孔灌注桩沉渣控制探讨

摘要

Based on the construction quality analysis of Jingtang Port 30 million tons coal berth 32#~34# project, the corresponding solutions have been put forward, which intensify the control of sediment thickness, increase the success rate of bore holes for the first time, ensure the boring cast-in-place piles going across sand layer under the complicated geological conditions and decrease the rework rate.%通过对京唐港3 000万t煤炭泊位(32#~34#)钻孔灌注桩施工质量分析,提出措施,加强沉渣厚度控制,提高一次成孔率.成功解决了钻孔灌注桩穿越沙层、地质情况复杂、返工率大等问题.
