The rock standard specimen of overlap type up and down that contact surface has 30 ° of inclination angles is prepared using the utility model, steps are as follows:
Step A, above-mentioned test material preparation device is assembled, movable plate 3 is covered in adjustment and is put horizontal by 30 ° of angles It sets, and is fixed slide bar 8 by clamping screw;
Step B, card slot 4 is fixed by bolts to and is covered above movable plate 3, sampling die 5 is then placed in card slot 4 It is interior, and fixed mold upper end with buckle 6;
Step C, two kinds of rocks analog material A and analog material B are prepared, before analog material pours, first in mold Vaseline is smeared in side, and convenient for demoulding, common process is can be used in the preparation of analog material A and analog material B;
Step D, analog material A is prepared into the preceding state of solidification, be then placed in sampling die 5, it is thick that thickness reaches setting It spends, in the present embodiment, with 50mm, (since mold 5 is in heeling condition, thickness is with cylindrical die center line for reference herein The thickness of scale) for;
Step E, entire sample preparation device is placed on oscillation certain time (generally 5~8 minutes) on concrete vibrating stand, It overflows the bubble in sample as far as possible, is then allowed to stand and materials A is allowed to reach preliminary initial set:
Step F, the analog material B prepared is directly placed above materials A, thickness reaches setting thickness, this implementation In example, by taking 51.5mm as an example, measurement method is identical as step D;
Step G, entire sample preparation device is placed on concrete vibrating stand, is made in material B by the way of intermittent oscillation Bubble overflow as far as possible, in the present embodiment, intermittent oscillation refers to oscillation a few minutes (usually 2~5 minutes), stops 2-3 point Then clock vibrates a few minutes (usually 2~5 minutes) again, then stops 2-3 minutes, about recycle 2-3 times.In oscillation In the process, the case where two kinds of material contacting surfaces being paid close attention to by transparent organic glass, to prevent interface to be mixed, such as Fruit has the tendency that generation intermixing, then reduces amplitude and the time of vibration;
Step H, after the completion of materials A, B are poured, (water conservation refers to that sample is constantly in the state being immersed in water, and guarantees for water conservation Sample is unable to the mode that water shortage is cracked, generallys use regular spray or impregnates) 12 hours are stood, reach analog sample Full initial set;
Step I, then card slot 4 is removed from upper cladding plate 3, unlocks upper end buckle 6 later, open mold 5, takes out initial set Sample afterwards, the concrete curing chamber that sample is put into constant temperature and humidity is maintained certain time on demand (service time is usually 7~ 28 days, the concrete curing standard time was 28 days, if requiring rapid prototyping, curing time is most short to can be compressed to 7 days or 14 It), to reach predetermined strength;
Step J, the rocks sample conserved is fixed on cutting rack, the extra part in sample upper end is cut off, It if there are out-of-flatness situation in sample bottom surface and side, can slightly be polished flat with sand paper, so far, obtain level just as about 30 ° Overlap type rocks 50 × 100mm specification standards mechanics test specimen.
The utility model prepares the proof force of the plurality of specifications such as 50 × 100mm in which can use analog material direct convenience Test specimen is learned, does not need to drill through by drilling machine;But also horizontal layer and inclination stratiform proof force test specimen can be prepared.
