大直径灌注桩桩端后注浆施工技术

Post-grouting Construction Technology of Large Diameter Cast-in-place Pile

文中主要研究了厦门白鹭西塔工程项目中大直径灌注桩桩端后注浆施工技术的应用,介绍了大直径灌注桩桩端后注浆技术施工过程,利用该技术将能够有效固化桩底沉渣并提高灌注桩承载力,从而提高超大直径灌注桩的施工质量。目前,灌注桩桩端后注浆作为较为先进的工程技术,在本项目的实践应用,对后续技术发展有着重要意义。

This article mainly studies the application of post-grouting construction technology for large-diameter cast-in-place piles in Xiamen Bailu West Tower Project, and introduces the construction process of post-grouting technology for large-diameter cast-in-place piles in detail. The technology will be able to effectively solidify the sediment at the bottom of the pile and improve the bearing capacity of the cast-in-place pile, thereby improving the construction quality of the super-large diameter cast-in-place pile. At present, the post-grouting of cast-in-place piles is a relatively advanced engineering technology, and its practical application in this project is of great significance to the subsequent technical development.
