Under complex geological conditions, the use of rotary drilling rigs to excavate pile foundations to form holes, unfavorable factors such as silt and groundwater will bring problems such as deviated holes and collapsed holes. Research on construction technology is required to overcome these difficulties. In this paper, the technology of rotary excavation and hole formation in a thick seam and high groundwater area of a seashore is studied. The influence of mud parameters and drilling speed on the quality of hole formation is explored. An efficient drilling rate and an economical and reasonable mud parameters are obtained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
