粉喷桩复合地基常用质量检测方法的对比分析

Comparison and Analysis on Common Methods of Quality Checking for Composite Ground of Cement Mixing Pile

粉喷桩用于地基处理,属于隐蔽工程。成桩质量受到天然地基土的性质、水泥用量、搅拌机械性能、施工工艺和人员素质等众多因素的影响,在实际工程中粉喷桩的质量检测和评价就成为其方案是否可行的重要依据。该文介绍了粉喷桩施工期和竣工期的常用检测方法。最后指出现有的检测方法各有利弊,有待进一步改进。

Often used for ground treatment, the cement mixing pile is concealed work. As the quality of pile is affected by many factors, such as the nature of raw ground, cement volume applied, mechanical features of mixer, construction process and the quality of personnel etc, the quality checking and evaluation of cement mixing pile became the basis for judging whether the scheme is feasible or not. Introduced in this paper are common checking methods for construction period and completion period of cement mixing pile, as well as their advantages and disadvantages.
