一、结构与原理三层双动岩心管的结构如图所示。冲洗液从双管接头的分水眼流入内外管的环状空间至孔底,经外管与孔壁的环状空间又返回孔口。岩心容纳管是由两根半合管组成,借助上下轴承座将两根半合管连成一体,保证岩心容纳管不随外、内岩心管的转动而转

First, the structure and principle Three double acting core tube structure as shown. Rinsing liquid from the double pipe joints of the water diversion into the inner and outer tube ring space to the bottom of the hole, the outer tube and the hole wall of the annular space and returned to the orifice. Core containment tube is composed of two semi-combined, with the upper and lower bearing block will be two semi-co-pipe connected to ensure that the core does not accommodate tube with the outside, the core tube rotation and turn
