Cement soil undisturbed coring device and cement soil undisturbed coring method
The invention discloses a cement soil undisturbed coring device and a cement soil undisturbed coring method, and aims to provide a cement soil undisturbed coring device which can obtain a cement soil core sample of a cement soil pile with a specified depth as required and can prevent the cement soil core sample from being disturbed in a sampling process. The invention discloses a cement soil undisturbed coring device and a cement soil undisturbed coring method. The cement soil non-disturbance coring device comprises a coring pipe, the upper end and the lower end of the coring pipe are open, and a protruding block is arranged at the bottom of the inner wall of the coring pipe. The cement soil undisturbed coring method sequentially comprises the following steps that firstly, before cement soil of a cement soil pile is solidified, a coring pipe is inserted into the cement soil pile from top to bottom; and secondly, the coring pipe is maintained in situ for T1 hours, and the coring pipe is pulled out upwards through a jack.
本发明公开了一种水泥土无扰动取芯装置及水泥土无扰动取芯方法，旨在提供一种既能够根据需要获取水泥土桩指定深度的水泥土芯样，又能够避免水泥土芯样因取样过程中受扰动，而影响水泥土芯样的性能指标的水泥土无扰动取芯装置及水泥土无扰动取芯方法。水泥土无扰动取芯装置，包括取芯管，取芯管的上下两端开口，取芯管内壁的底部设有凸块。水泥土无扰动取芯方法，依次包括以下步骤，第一，在水泥土桩的水泥土凝固之前，将取芯管自上而下的插入水泥土桩内；第二，将取芯管保持在原位养护T1小时，使用千斤顶将取芯管往上拔出。
