Abstract
The present invention relates to a kind of preparation method of rock post, more particularly to a kind of preparation method that need to measure rock post multiple directions change in size：（1）Use the rock post of cutting machine cutting certain size；（2）Punched at the center of described rock post both ends cross section；（3）Punched at the rock post side axisymmetric position；（3）Into hole, filling concrete is starched；（4）Measuring piece is assigned into hole.The present invention selects three different directions, ensures the accuracy of experimental data.
Description
Technical field
The present invention relates to a kind of preparation method of rock post, more particularly to one kind need to measure the change of rock post multiple directions size
The preparation method of change.
Background technology
Most of rocks have grain, and the performance in each direction is different, and the composition and line in each region of rock of the same race
Reason also has more or less change, in order to reduce the influence of these factors, the study of rocks single direction in rock expansion experiment
Strain be inadequate, the expansion character of multiple directions need to be considered, and then draw the performance of the rock.
The content of the invention
The present invention measures the length change of same three different directions of rock post to avoid experimental error as far as possible,
Ensure the accuracy of experiment.
The experimental program taken of the present invention is：A kind of preparation method of rock post（1）A scale is cut using cutting machine
Very little rock post；（2）Punched at the center of described rock post both ends cross section；（3）In the rock post side axial symmetry
Opening position is punched；（3）Into hole, filling concrete is starched；（4）Measuring piece is assigned into hole.
Further, in more detail, described rock post is cylinder, and the both ends of described cylinder are equal for diameter and height
More than 3cm.
Further, in more detail, described rock post side is equipped with four holes, and described four holes are in a center of symmetry.
Further, in more detail, wait to the cement solidifies after assigning measuring piece, measure.
Further, in more detail, described hole depth is 1mm-2mm.
The beneficial effect that the present invention is realized（1）Using cylindrical rock post, compound with regular structure, it is straight that cylinder cutting machine can be selected
Tap into capable cutting；（2）Use cement fixation measuring part, fixation；（3）From three different directions, ensure experimental data
Accuracy.
Embodiment
Further detailed description is done to the present invention below in conjunction with embodiment, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
A kind of rock column preparation method, comprises the following steps（1）First by existing cylinder cutting machine, in large rock mass
On cut rock post, the basal diameter and height of rock post are all higher than 3cm；（2）Punched in the bottom center of rock post, hole depth
For 1mm-2mm；（3）Four holes circumferentially are made a call in rock post side, four holes are centrosymmetric, hole depth 1mm-2mm；（4）To
Filling concrete mortar in hole；（5）By in the patchhole of measuring piece one end, after hardening of cement, measuring piece is fixed with rock post；（6）
Pass through the measurement of measuring instrument and measuring piece to rock post direction length change.Measuring instrument in the present invention is spiral micrometer
Device or slide measure, the measuring piece in the present invention is measurement termination, and measuring piece contacts with measuring instrument during measurement.
