松散岩样三轴夹持器的研制

A New Development of Triaxial Gripper for Loose Rock Sample

为了便于测试地下松散岩样,研制了松散岩样三轴夹持器。其胶筒外围设有胶筒保护套,利于岩样充填均质而不损坏胶筒,且取下胶筒保护套即可用作普通的岩心夹持器,应用广泛,实用性强;其一端设有轴压柱塞,在实验过程中始终压紧岩样,不会造成压馈岩样影响实验的顺利进行。实验表明,该夹持器岩样充填均质,测试准确,可代替成形岩心进行测试。

In order to test underground loose rock sample conveniently,a triaxial gripper for loose rock sample is developed.The rubber cylinder is surrounded by a rubber cylinder protective sleeve,which is good for filling rock samples evenly without damaging the rubber cylinder.The rubber cylinder protective sleeve can be taken off from the triaxial gripper,and then it can be used as an ordinary core gripper.The triaxial gripper for loose rock sample can be widely used and has strong practicability.At one end of the triaxial gripper,an axially compressed plunger is installed,which always compresses the rock samples during the experiment process to keep the experiment running smoothly.Experiments show that the gripper can be filled evenly and test accurately,and loose rock sample can replace the formed core for testing using this equipment.
