摘要
针对某特大桥超深钻孔灌注桩桩底混凝土出现的缺陷,详细介绍了利用钻探取芯孔和声测管切割后进行高压水清孔,然后压注高标号水泥浆的处理技术和工艺流程,为今后处理类似工程质量事故积累了经验。
In light of concrete defects at the bottom of extra deep bored pile of the great bridge,it specifically introduces the processing technique and technical procedure by using drilling core hole and sound test tube cutting,cleaning hole with high-pressure water,and then injecting slurry premium.Thus,it has accumulated experiences for processing future similar engineering quality accidents.
