目前一般在岩层破碎孔壁掉块的情况下,进行压水试验时,往往由于为了防止掉块将栓塞埋于孔内,使得试验不能很好进行,而影响地质资料的取得,为了解决这一问题,我们采用了安装取块管的办法。于栓塞上端的工作管外面套一管子,我们称它为取块管,其大小视试验段上部的孔 At present, it is common to break off the hole wall of a rock formation in the case of water block test. In order to prevent the block from being buried in the hole, the test can not be performed well and the acquisition of geological data is affected. In order to solve this problem Problem, we used to install the way to take the tube. In the plug on the top of the tube outside the tube set a tube, we call it take the tube, the size of the upper part of the hole as the test section
