Description
Technical Field
The utility model relates to an experimental technical field of geotechnical engineering, concretely relates to concrete rock interface sample making devices for shear strength test.
Background
At present, underground space development becomes the trend of urban development, therefore bring a large amount of underground constructions, to the underground structure that is located on the rock foundation, can form the adhesion between concreting cushion and soleplate and the rock, the size of this adhesion need obtain through the experiment, and the current way is gone on at the scene, and the operation process is very loaded down with trivial details, and consuming time and power, and the cost is very big. If change indoor test, then can be simple a lot, for obtaining accurate concrete rock adhesion strength in indoor test, need a set of device that can make and contain concrete rock interface sample urgent.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a concrete rock interface sample making devices for shear strength test, can bore and obtain the core appearance that the concrete rock interface is located in the middle of the core appearance cross section to further obtain the sample that satisfies the shear test requirement in core appearance cutting process.
In order to achieve the above purpose, the utility model adopts the following technical proposal: it comprises cutting rock blocks and concrete blocks; a concrete block is arranged above the cutting rock block; it also includes:
the number of the L-shaped steel plates is two, and the two L-shaped steel plates are arranged diagonally to form a die; the cutting rock and the concrete block are both arranged in the mould.
Preferably, the peripheral wall of the cutting rock block is cut into a flat structure, and the upper surface of the cutting rock block is a natural state structure.
Preferably, the connecting pieces are fixed on the connected side edges of the L-shaped steel plates, through holes are formed in the connecting pieces, and bolts are arranged in the through holes in the two connected connecting pieces in a penetrating manner.
After the structure is adopted, the beneficial effects of the utility model are that: the utility model provides a concrete rock interface sample making devices for shear strength test through dismantled and assembled mould, becomes concrete rock piece with concrete placement to through exerted interface line all around, can bore and obtain the core appearance that the concrete rock interface is located in the middle of the core appearance cross section, and further obtain the sample that satisfies the shear test requirement in core appearance cutting process.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 4, the following technical solutions are adopted in the present embodiment: the cutting rock comprises a cutting rock block 1 and a concrete block 2; a concrete block 2 is arranged above the cutting rock block 1; it also includes:
the number of the L-shaped steel plates 5 is two, and the two L-shaped steel plates 5 are arranged diagonally to form a die; the above-mentioned cut rock block 1 and concrete block 2 are both set in the mold.
Preferably, the circumferential wall of the cutting rock block 1 is cut into a flat structure, and the upper surface of the cutting rock block 1 is a natural state structure.
Preferably, connecting pieces 6 are welded on the connected side edges of the L-shaped steel plates 5, through holes 7 are formed in the connecting pieces 6, and bolts are arranged in the through holes 7 of the two connected connecting pieces 6 in a penetrating mode.
Utilize the utility model discloses the flow of preparation sample as follows:
firstly, selecting flat rock blocks from an engineering site, transporting the flat rock blocks to a laboratory for cutting, cutting the peripheral sides of the flat rock blocks to be flat, and keeping the upper surfaces of the rock blocks in a natural state to form cut rock blocks 1; splicing two L-shaped steel plates 5 with the same shape into a die, and fastening by utilizing bolts to match with through holes 7;
then, placing the cut rock block 1 into a mould, pouring concrete on the cut rock block to form a concrete block 2, and removing the mould after the concrete is solidified to obtain a concrete rock block body;
then, drilling a core sample 4 along the direction of a concrete-rock interface 3 (namely the adjacent interface of the cutting rock block 1 and the concrete block 2) on the side surface of the concrete-rock block body, and enabling the concrete-rock interface 3 to be positioned in the middle of the cross section of the core sample 4;
finally, the drilled core sample 4 is cut to the desired dimensions for the shear test into test specimens 8.
After adopting above-mentioned structure, this embodiment's beneficial effect is: the concrete rock interface sample manufacturing device comprises a detachable mold, wherein a concrete block and concrete are poured into the concrete block through the detachable mold, a core sample with a concrete rock interface positioned in the middle of the cross section of the core sample can be obtained through an exposed interface line on the periphery, and a sample meeting the requirements of a shear test is further obtained in the cutting process of the core sample.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
