Grouting Treatment of Sedimentary Dregs of Cast-in-place Bored Pile Bottom
-
摘要: 对桩底沉渣产生的原因、沉渣对灌注桩承载能力的影响以及沉渣的处理作了简要分析，讨论了灌注桩桩底压浆工艺的作用机理。重点结合实际工程介绍了该技术，经检测表明，灌注桩桩底压浆技术的使用有效地处理了沉渣，提高了桩的承载能力。Abstract: The reasons for sediment,sediment's effect on the bearing capacity of cast-in-place bored pile and treatment with sediment are analyzed,and the effecting mechanism of grouting at the piles bottom is discussed. The technique is emphasized by means of practical work. The test indicates that grouting at the piles bottom is an effective method to deal with sediment and it improves the bearing capacity of piles.
