Device and method for preparing anchoring and filling cylindrical rock sample

The invention relates to the technical field of rock samples, in particular to a device and method for preparing an anchoring and filling cylindrical rock sample, in the process of pouring, anchoring and filling surrounding rock, an upper filling rock, a filling material and a lower filling rock are sequentially arranged from top to bottom, and therefore the needed filling rock sample can be obtained; then the top end of the upper filling rock is flush with the first footstock, so that an anchoring filling cylinder rock sample can be prepared, and then the anchoring filling cylinder rock sample is adopted to carry out a mechanical property test and a rheological test under corresponding conditions, so that the problem that in the prior art, in the process of pouring, anchoring and filling surrounding rock, the anchoring filling rock cannot be subjected to mechanical property test and rheological test is solved; a technology for anchoring and filling a cylindrical rock sample is rarely introduced, so that a me
