-
摘要: 通过工程实例,介绍了后注浆技术及其在提高硷钻孔灌注桩承载力方面的效果检测,并提出了通过注浆管采用声波透射法对桩身进行检测的理论与实践,同时总结了后注浆硷灌注桩检测中应注意的问题。Abstract: Through engineering case, after grout injection technique and its result check for improvement on bearing capacity of concrete bored pile are introduced. The theory and practice of inspection on the pile adopting sonic transmissing-beam method through grout pipe are also advanced. The problems worth attention. of inspection on concrete filling pile after grout injection.
