摘要
结合中铁世界博览城会展及配套项目岩土工程详细勘察钻孔实践,针对地层复杂,钻孔过程中发生的泥浆严重漏失、卡钻、埋钻等现象,采取了优质泥浆护壁、注浆、下套管、优化钻进参数等行之有效的技术措施,提高了施工效率,降低了成本,取得了非常明显的技术效果。
Combining with the drilling practice of the detailed investigation for geotechnical engineering of China Railway world expo city and the matching projects,in view of the complicated formations,serious mud leakage,drill pipe sticking and burying in the drilling process,some effective measures,such as wall protection with high quality mud,grouting,casing putting and drilling parameters optimization,are taken to improve the construction efficiency and reduce cost,and obvious technical results have been achieved.
