后注浆技术在钻孔灌注桩中的应用

摘要

This paper takes the project of Pingtan Xiehe Hospital as an example,elaborates on the post grouting technology of cast-in-place bored pile,introduces pile-end grouting pile reinforcement mechanism,the relationship between quantity and time,etc.,in order to provide references for future similar engineering construction.%本文以平潭协和医院项目为工程实例,对冲孔灌注桩后注浆技术进行了阐述,对桩端注浆加固机理、注浆量与时间的关系等方面进行了介绍,为以后同类工程施工提供参考.
