水泥搅拌桩两种取芯检测方法比较

The Comparison between the Two Methods of Sampling Survey for Cement Mixing Pile

通过对双管双动岩芯管和常规的双管单动岩芯管两种取芯设备所抽取的水泥搅拌桩芯样特征及试验强度等进行分析对比 ,认为采用双管单动岩芯管进行水泥搅拌桩取芯检测比较合适。

Through the analyses and comparisons on the characteristics and test strength for the cement mixing pile core sample taken by the sample devices of double tube double swivel barrel and the traditional double tube single swivel barrel,it is considered that the traditional double tube single swivel barrel is more suitable to the sample survey of cement mixing pile.
