Description
Technical field
The utility model relates to indoor rock sample preparation facilities, more specifically relates to a kind of indoor simple check crack rock sample preparation facilities, belongs to the Geotechnical Engineering technical field.
Background technology
Problems such as cracking, load-bearing capacity reduction, perviousness enhancing and then chance water softening inevitably will appear in rock mass in the on-the-spot digging process of engineering rock mass, and therefore, grouting and reinforcing becomes the important technique measure in rock mass engineering project field in certain range of disturbance.But the rock cranny shear resistance promotes the problem that the assessment of effect is this domain engineering of puzzlement technician always after the slip casting; Get at the scene under the unsuccessful situation of core method,, and make slurries by on-the-spot proportioning if generate fissure-plane at indoors artificial; Carry out the direct shear test of slip casting fissure-plane; And compare with no slip casting situation, can make assessment well, for engineering design provides basic foundation.But; In the process that simple check crack rock sample is made; The crack up and down concentricity, two of the core indexs such as the depth of parallelism and adhesive layer thickness that load end faces is difficult to accurately control, can't satisfy the requirement of shop experiment to the rock sample preparation, also accurate simulated field actual conditions; Therefore, carrying out of relevant mechanical test and obtaining of design considerations have seriously been restricted.
Summary of the invention
The purpose of the utility model is to be to provide a kind of simple in structure, easy to use, practical, can make things convenient for simple check crack rock sample preparation facilities in the preparation room.
To achieve these goals, the utility model adopts following technical measures:
A kind of indoor simple check crack rock sample preparation facilities, preparation facilities is made up of base, the movable seat of honour, bottom core retaining collar, top core retaining collar, threaded spindle, adjusting nut, fastening nut, has the groove that connects upper and lower surfaces on base one end; The threaded spindle lower end connects fixedly calotte, and groove is passed in the threaded spindle upper end, is fixed on the top of base through fastening nut; Threaded spindle has the keyway of perforation along axis direction, and the movable seat of honour one end has circular hole, has keyway in the circular hole; Key is fixed in the keyway of circular hole; The movable seat of honour is sleeved on the threaded spindle through key, and the keyway sliding contact on key and the threaded spindle has the horizontal groove vertical with end wall on the end wall of the other end at the movable seat of honour; Fastening nut that the above and below at the movable seat of honour is respectively equipped with and adjusting nut; The horizontal groove at the core retaining collar insertion activity seat of honour, top, and through bolt, bottom core retaining collar is through being bolted on the base.
Have equally distributed radial screw bore on top core retaining collar and the bottom core retaining collar ring wall.
The internal diameter equal and opposite in direction of top core retaining collar and bottom core retaining collar.
Owing to adopted above technical scheme, this indoor simple check crack rock sample preparation facilities has following advantage:
1 in order to guarantee rock sample top core and bottom core concentricity; Two groove designs have been adopted at the base and the movable seat of honour; Can regulate position, the left and right sides and the top core retaining collar of threaded spindle groove on base front and back position at the movable seat of honour; Adopt the threaded spindle design that splines, can move along the axial single direction of threaded spindle at the assurance activity seat of honour, prevent that the movable seat of honour from swinging in the process of moving up and down; Thereby can keep that the concentricity of top and the bottom core satisfies the standard sample requirement behind the fracture filling binding material, so that Experiments of Machanics such as shear.
2 in order to guarantee that rock sample loads the depth of parallelism of end face up and down; The retaining collar of top core and bottom core adopts parallel design; Bolt tightening sample around top core retaining collar and bottom core retaining collar pass through; The bottom core is after base is fixing, and the end face of top core flushes with top retaining collar top end, can satisfy shop experiment loads faces parallel up and down to rock sample requirement.
3 adopt adjusting nut and fastening nut design; Can accurately quantitatively the movable seat of honour be moved either up or down to the distance that experiment needs; Ensured the adhesive layer thickness between top core and the bottom core, accomplished the butt coupling of top core and bottom core, to satisfy the needs of shop experiment.
The indoor simple check crack rock sample preparation facilities of the utility model has solved the difficult problem that present indoor simple check crack rock sample is difficult for making; Indoor simple check crack rock sample preparation facilities is rational in infrastructure, simple; Be easy to make; Simple to operate, practical, can generally be used for the preparation of the indoor simple check of various models crack rock sample.
