灌注桩后注浆施工技术在建筑工程施工中的应用研究

Application Research of Post-Grouting Construction Technology of Cast-in-Place Pile in Construction Engineering

为减少建筑工程施工中桩体沉降,解决传统注浆施工中桩基底存在泥皮、沉渣等问题,加强科学施工技术的应用,论文介绍了灌注桩后注浆施工技术的工作原理,探讨其应用优势,并基于工程案例,从前期的注浆管制作、压水实验以及后期的注浆管安装、注浆等多道施工工序详细研究了灌注桩后注浆施工技术的应用。

In order to reduce the settlement of pile in construction engineering,control the problems of mud skin and sediment at the bottom of pile foundation in traditional grouting construction,and strengthen the application of scientific construction technology,this paper introduces the working principle of post-grouting construction technology of cast-in-place pile,discusses its application advantages,and based on engineering cases,the application of post-grouting construction technology of cast-in-place pile is studied in detail from the grouting control operation in the early stage,water pressure experiment,grouting pipe installation,grouting and other construction procedures in the later stage.
