钻孔灌注桩桩底后注浆机理与应用研究

Study of mechanism and application on bored pile end grouting

摘要

摘要: 系统阐述了持力层为砾石层的钻孔灌注桩的桩底后注浆机理和工艺，并给合工程实际分析研究了注浆压力、浆液浓度、注浆量、注浆半径和注浆效果。

Abstract: This paper explains the mechanism and technology of grouting under bored piles whose bearing stratum is grit.Based on four examples,grouting pressure,grout density,grouting capacity,grouting radius and grouting effect has been analyzed and studied.
