高水位复杂环境及地质条件下旋挖桩施工技术

Construction Technology of Rotary Excavation Pile under Complex High Water Level Environment and Geological Conditions

以罗平县妇幼保健计划生育服务中心建设项目为研究对象,对高水位、周边复杂环境及岩溶地质条件下的旋挖灌注桩施工技术做了一定的研究,通过对特殊条件下旋挖灌注桩旋挖成孔一次成孔率的影响因素的分析,结合实际施工条件,比选出最合理的施工技术措施,确保旋挖灌注桩的成孔水平和成孔质量,从而有效地提高了工程整体施工效率。

Taking the construction project of the Maternal and Child Health and Family Planning Service Center in Luoping County as the research object,this paper studies the construction technology of rotary excavation and grouting piles under high water level,complex surrounding environment,and karst geological conditions.By analyzing the influencing factors of the one-time drilling rate of rotary excavation grouting piles under special conditions,combined with actual construction conditions,the most reasonable construction technical measures are selected to ensure the drilling level and quality of rotary excavation grouting piles,thereby effectively improving the overall construction efficiency of the project.
