摘要
以某酒店工程为例,详细阐述大直径混凝土灌注桩在煤田采空区的施工要点,包括定位,成孔,护筒,水下混凝土浇筑等几个方面,重点介绍水下混凝土浇筑的工艺流程及施工措施,以及施工中各技术参数的计算,为煤田采空区的地基处理提供了可借鉴的施工经验。
Taking some hotel project as the example,the paper illustrates the construction points of the large-diameter concrete filling piles at coal mine goaf,including the positioning,pore-forming,pile casing and underwater piling,and mainly introduces the craft procedure and construction measures of the underwater piling,as well as the calculation of various technical parameter,so as to provide some construction experience for the foundation treatment at coal mine goaf.
