Description

The preparation cutter sweep containing different angle structural plane rock sample

Technical field

This utility model relates to rock mechanics experiment technical field, is specifically related to one and prepares containing not Cutter sweep with obliquity structure face rock sample.

Background technology

Rock mass is to compose to be stored in certain geological environment, cut by different structure face and have one Determine the natural object of engineering Geological Characteristics.Experience different times, the geological structure fortune of different scales After Dong, rock mass is internally formed the geological interface of different origins, different qualities, as tomography, joint, Aspect and crack etc., be referred to as structural plane.Structural plane generally exists in rock mass engineering project region, and Directly affect the stability of rock mass engineering project.

With landing ground, the developing rapidly of underground rock engineering, the increasing energy, traffic, Mine, water conservancy and defence engineering are built in the rock mass region containing structural plane, its engineering design, execute Work and safety evaluation (intensity, deformation, stability, durability etc.) all depend directly on rock The research of the features such as body intensity, deformation and failure law thereof.

The quantitative test of Mechanical property, is mainly carried out by large-scale in-situ test, but its Long in time limit, investment is big, operation is many.Rock mechanics experiment is the basis of rock mass mechanics, is research One of important means of rock mass mechanics and engineering, determines offer foundation for rock mass parameter, affects The design of rock mass engineering project and construction.Therefore, the true and reliable property of rock indoor mechanical test result Most important.

The premise of rock mechanics experiment is the rock sample that processing preparation Pass Test requires.At present, Mostly indoor rock mechanics experiment is to prepare complete rock sample, and the rock mass in Practical Project is many Containing the structural plane such as crack, joint, the result of the test of intact rock sample can not represent containing crack, The structural plane rock mass such as joint.Therefore, structural plane such as research crack, joint etc. is special to rock mass mechanics Property, the impact of failure mechanism be accomplished by preparation containing the structural plane such as crack, joint special rock examination Sample.

Rock mechanics laboratory Technical comparing in terms of the complete rock sample of the standard of making both at home and abroad Mostly maturation, be to drill through longer core first with minor diameter rock core drilling rig, then pass through rock Cutting machine cuts into required rock sample.But making containing different angle crack, joint etc. The rock sample aspect of structural plane, owing in preparation process, cutting angle is difficult to accurately control, its Manufacturing technology and processing unit (plant) still need to improve further, perfect so that laboratory makes through, The key rock sample in non-through structure face is difficult to see report.

Existing rock cutter uses a fixed dam mostly, by rock is against baffle plate The upper realization cutting to rock, but only cannot realize cutting rock by a fixed dam Overall fixing, rock sample cutting process easily produces angle skew, disrumpent feelings；It addition, It is generally fixed on base motionless, along with rock owing to installing the supporter of cutting machine cutter sweep The increase of sample depth of cut, the cutting arc line length between cutting blade and rock sample can be held Continuous increase, necessarily causes frictional force between cutting blade and rock sample to increase, and motor load increases Greatly.Meanwhile, high temperature and chip removal difficulty that frictional force produces will also result in cutting blade and damage, limit Make cutting specimen size.

Along with people recognize destruction more of stress and the coefficient result of structure of rock mass, Present in rock mass, structural plane plays control action for the stability of rock mass engineering project so that containing knot The research of the physico mechanical characteristic of structure face rock mass is increasingly becoming focus.Therefore, preparation in laboratory Meet the standard size rock sample containing structural planes such as different angle crack, joints of test requirements document And develop corresponding cutting processing device and become current urgent problem.
