摘要
分析钻孔灌注桩施工中导致孔底沉渣过厚的主要因素,介绍沉渣厚度的检测方法,提出选择合适的清孔方法、严格控制清孔泥浆指标、有效固孔及尽量缩短清孔至混凝土灌注之间的时间间隔等减小和控制钻孔灌注桩孔底沉渣厚度的具体措施。
Analysis the reason of precipitation thickness in the pile construction, Introduce the test method of precipitation thickness, Proposed the appropriate method of cleaning precipitation and control index of slurry and reinforcing the bored wall,and shortening the time interval between bore cleaning and bore perfusion and so on.
