摘　　要：桩端后注浆为隐蔽工程,注浆后浆体在地底的活动过程无从观察。为了控制超长冲孔灌注桩桩端后注浆的施工质量,通过文献资料法、统计及调查分析法研究分析出质量问题存在的具体施工环节,通过控制注浆管套管及连接施工质量、采取正确的焊接方式、控制注浆管连接垂直度等措施,有效保证了注浆量、注浆压力和持荷时间,从而控制了超长冲孔灌注桩桩端后注浆的施工质量。实践中采取文献资料法、统计及调查分析法制定施工技术措施,使施工技术的应用具有针对性和科学性。Research purposes： Control of super long bored pile post grouting construction quality; Research methods： The pile end post grouting technology for concealed works, slurry is not observed in the bottom grouting process, by u- sing the methods of literature, statistics and analysis to research and analysis of specific aspects of the construction quality problems, in order to achieve the ideal effect through the grouting quality control of each construction link ; The results of the research： Through the control of grouting pipe connection sleeve and construction quality, the proper welding manner is adopted, control of grouting pipe connection between such measures, effectively guarantee the quan- tity of grouting, grouting pressure and holding time, so as to control the super long bored pile post grouting construction quality; The conclusion of the research： Should take the literature method, survey method and statistical analysis to formulate the construction technicalmeasures, make the scientific. application of the construction technology of the targeted and
