preparation example Construction

[0073] According to an embodiment of the present invention, the preparation method uses the above-mentioned sample preparation device for cemented granular materials, and, referring to Figure 5 , the preparation method comprises:

[0074] S100: Combine the base, the slurry plate and the sample preparation cylinder, and put the limit sleeve on the outside of the sample preparation cylinder.

[0075] In this step, the base 1 , the slurry plate 2 and the sample preparation cylinder 3 are combined, and the limit sleeve 4 is placed on the outside of the sample preparation cylinder 3 to seal the sample preparation cylinder 3 .

[0076] According to the embodiment of the present invention, the specific method of combining the base 1, the slurry plate 2, the sample preparation cylinder 3 and the limit sleeve 4 is not particularly limited, and those skilled in the art can carry out according to the specific shape of the sample preparation cylinder 3 Adjustment. In some embodiments o...

Embodiment 1

[0092] In this example, refer to Figure 1~4 The cemented granular material sample preparation device.

[0093] Among them, the sample preparation mechanism includes a sample preparation cylinder 3. The sample preparation cylinder 3 is composed of two split semicircular tubes. And use the limit cylinder 4 to seamlessly seal the sample preparation cylinder 3; the bottom end of the limit cylinder 4 is fixed on the permeable plate 2; the sealing plate 11 can be fixed on the permeable plate 2 by springs and bolts 12; the upper surface of the pouring plate 13 is engraved with The second groove 15 has the same inner and outer diameters as the inner and outer diameters of the pouring cylinder 14; the pouring cylinder 14 is embedded in the second groove 15 on the upper surface of the pouring plate 13; 2 have the same outer diameter; the pouring plate 13 is fixed on the upper end of the limiting cylinder 4; the raised end of the lower surface of the pouring plate 13 seals the upper su...

Abstract

The invention provides a cement particle material sample preparation device and a method for preparing a cement particle material sample. The cement particle material sample preparation device comprises a sample preparation part, wherein the sample preparation part comprises a base, a slurry penetration plate arranged above the base and provided with a plurality of first slurry penetration holes,a sample preparation drum with the lower end embedded into a first groove of the slurry penetration plate, and a limiting drum sleeving the outer wall of the sample preparation drum and used for sealing the sample preparation drum, wherein the sample preparation drum and the slurry penetration plate form a sample preparation cavity. According to the sample preparation device, the limiting drum ofwhich the size is matched with that of the sample preparation drum can sleeve the outer side of the sample preparation drum, so that the airtightness of the sample preparation drum and the close fitting between the sample preparation drum and the slurry penetration plate can be improved, and accordingly, a dense and porous cement particle material sample can be obtained.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular, the invention relates to a sample preparation device for cemented granular materials and a method for preparing samples of cemented granular materials. Background technique [0002] Cementitious granular material is a kind of bulk granular material poured from self-compacting cement-based materials, polymers and other gels, including rockfill, pebbles, sand, etc., through the hydration reaction of cement-based materials or polymers The curing reaction bonds the loose granular material into a whole with high strength. The cemented granular material is widely used in many fields of geotechnical engineering, such as mine goaf filling, diseased dam reinforcement, slope grouting reinforcement and foundation treatment Wait. Cemented granular materials are different from bulk materials such as rockfill, and also different from solid materials such as concrete, but a...
