Description

Technical Field

[0001] The invention belongs to the technical field of rock mass models, and in particular relates to a mold for making a rock-like specimen containing a filled joint surface and a use method thereof. Background Art

[0002] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention, and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0003] Rock masses in nature are formed through long-term geological processes such as construction and transformation, so they inevitably contain natural defects such as joints and fissures, which are collectively referred to as joints here. The existence of natural defects such as joints not only provides crack sources for the destruction of rock masses, but also the stress concentration at the tips of joints can induce low-stress brittle fracture of rock masses. A large number of studies and engineering practices have shown that the destruction of rock mass engineering is mostly related to the evolution, expansion and penetration of the original joints of the rock mass. According to the different occurrence states of joints in the rock mass, they can be divided into filled joints and unfilled joints, through joints and non-through joints, etc. The low strength and large deformation characteristics of the filling material will also change the mechanical properties of the structural surface and the strength of the entire rock mass, increasing the instability of the engineering rock mass. Therefore, the study of various forms of rock mass joints is of great significance; many researchers use molds to make rock-like specimens with cracks for research.

[0004] In the current process of making rock-like specimens, rock-like specimens are usually prepared by pouring filling materials in the reserved joints of rock specimens, or by 3D printing to prepare roughness interfaces to characterize non-filled joints. The above-mentioned cast-in-place reserved joint filling joint production method has many shortcomings. For example, the reserved joints are usually realized by inserting and pulling thin slices. This method can only produce two-dimensional rough filling joint surfaces with uniform height; and the filling process of the filling material added to the reserved joints cannot be visually seen, and it is difficult to judge whether the inside is full of gaps, which affects the test effect of the specimen. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a mold and a method for making a rock-like specimen containing filled joint surfaces. The filling joint material is first made, and then the rock-like test is made. The position of the filled joints can be accurately controlled, and rock-like specimens with filled joint surfaces with coplanar or non-coplanar relationships can be prepared to meet the needs of various test schemes.

[0006] In order to achieve the above object, the technical solution of the present invention is:

[0007] In the first aspect, a mold for making a rock-like specimen containing a filled joint surface comprises a bottom plate, a chute vertical plate and a common vertical plate; the chute vertical plate is installed on a set of opposite side edges of the bottom plate, the common vertical plate is installed between two chute vertical plates, and is perpendicular to the chute vertical plate and the bottom plate respectively; the bottom plate, the two chute vertical plates and the two common vertical plates together form a box structure with a bottom, and the chute vertical plate can slide along the direction of the side edge of the bottom plate on which it is installed; the distance between the two common vertical plates can be adjusted;

[0008] The chute vertical plate is provided with an inwardly concave filling joint groove, and the length direction of the filling joint groove is perpendicular to the upper surface of the bottom plate.

[0009] In a second aspect, the method for using the mold for making a rock-like specimen containing a filled joint surface comprises the following steps:

[0010] S1, assembling the chute vertical plate, the common vertical plate and the bottom plate into a box body, wherein the filling joint groove is located inside the box body, and a rock mass including relative splitting surfaces is placed in the box body, wherein the splitting surfaces of the rock mass are at a set distance, and the gap between the relative splitting surfaces is connected to the filling joint groove;

[0011] S2, pouring the filling joint material into the relative cleavage surface, and allowing the filling joint material to fill the filling joint groove; allowing the filling joint material in the filling joint groove to form a mounting protrusion protruding outward from the rock mass, thereby obtaining an installable filling joint block;

[0012] S3, assembling the chute vertical plate, the common vertical plate and the bottom plate into a box body, moving the relative chute vertical plates installed on the bottom plate, so that the two relative filling joint grooves are in a coplanar or non-coplanar state, and installing mounting protrusions of different filling joint blocks in the two relative filling joint grooves respectively;

[0013] S4. Pour cement mortar into the box, complete curing, and obtain a rock-like specimen containing filled joint surfaces.

[0014] The beneficial effects of the present invention are:

[0015] The present invention includes a filling joint groove, and the filling joint material filled in the filling joint groove can be solidified into a mounting protrusion, and the mounting protrusion is used for positioning the filling joint surface, and the position of the filling joint surface can be accurately adjusted, so that the width, depth and number of the joint surface can be controlled according to the prefabricated filling joint surface. The concave filling joint groove can produce a mounting protrusion that fixes the position of the filling joint surface, and the position of the filling joint surface can be adjusted by moving the chute vertical plate with the filling joint groove, so as to prepare a coplanar or non-coplanar filling joint structure, and realize the production of natural filling joint surface rock specimens. The chute vertical plate and the ordinary vertical plate of the present invention are both detachably installed, and the position of the chute vertical plate relative to the bottom plate can be adjusted by the first long groove. When the chute vertical plate is fixed, the spacing of a group of ordinary vertical plates can be adjusted by the second long groove. The shape and size can be changed flexibly, and the assembly and disassembly are convenient. Various forms of rock joint structures can be produced, which are suitable for different research requirements. The entire production process is visualized, avoiding the problem of uneven filling caused by the inability to visually observe the filling material added to the reserved gap in the past.

[0063] S1, assemble the chute riser 2, the common riser A31 and the bottom plate 1 into the following Figure 1 In the box shown in FIG. 1 , one of the filling joint grooves 4 is located inside the box, and the other of the filling joint grooves 4 is located outside the box. Figure 7 As shown, a rock mass 6 including relative splitting surfaces is placed in the box, the splitting surfaces 61 of the rock mass 6 are at a set distance, and the gap between the relative splitting surfaces 61 is connected to the filling joint groove 4;

[0065] S3, assemble the chute riser 2, the common riser B32 and the bottom plate 1 into the following Figure 2 The box shown, such as Fig. 9 As shown, the relative positions of the slide groove risers 2 installed on the moving bottom plate 1 are made so that the two relative filling joint grooves 4 are in a coplanar or non-coplanar state, and the mounting protrusions 51 of different filling joint blocks 8 are respectively installed in the two relative filling joint grooves 4, so that the cleavage surfaces 61 of the different filling joint blocks 8 are in a coplanar or non-coplanar position;

[0066] S4, pour cement mortar 9 into the box body, complete the curing, and obtain Fig.10 The rock-like specimen shown contains filled joint surfaces; after preparation, the mounting protrusion 51 is removed by a rock cutter.

[0067] In the above process, a filling joint block 8 with a mounting protrusion 51 is first manufactured, and then the position of the splitting surface 61 is accurately located using the mounting protrusion 52, and then a rock-like specimen including a plurality of filling joint blocks 8 is manufactured, so that the plurality of splitting surfaces 61 satisfy different relationships such as coplanar or non-coplanar, thereby improving the degree of similarity between the prepared rock-like specimen and the actual rock and meeting various experimental requirements; since the mounting protrusion 51 is inserted on the box, the error of the internal structure of the prepared rock-like specimen being changed due to the displacement of the filling joint block 8 during the pouring of the cement mortar 9 can be avoided.

[0072] Example 3

[0073] The method for using the mold for making a rock-like specimen containing a filling joint surface in Example 1 is different from that in Example 2 in that: in S2, after the filling joint material 5 is initially set, the filling joint block 8 can be removed, and only the rough surface of the filling joint material 5 formed by the filling joint block 8 is retained. In S3, after positioning by using the mounting protrusion 51, cement mortar 9 is poured into the box body in the same way as in S4, so that a joint surface containing coplanar or non-coplanar joints with adjustable width and position can be made, such as Fig.11 shown.

[0074] Example 4

[0075] The method for using the mold for making a rock-like specimen containing a filled joint surface of Example 1 comprises: preparing a plurality of rock-like specimens with different filled joint surfaces:

[0076] In S1, when the chute riser 2, the common riser B32 and the bottom plate 1 are assembled into a box body, a cavity with a longer length relative to the cleavage surface 61 can be obtained, thereby preparing filling joint materials 5 of different lengths.

[0077] In S2, after the filling joint material 5 has initially set, the filling joint block 8 can be removed, and the filling joint material 5 can be taken out, and the installation protrusion 51 can be cut off by a rock cutting machine.

[0078] In S3, the filling joint material 5 after the installation protrusion 51 is cut off is placed at the set position on the left edge of the box body using the scale of the device. The second filling joint material 5 is placed at a set distance to the right of the placed filling joint material 5, and so on, and finally the cement mortar 9 is poured to fill the remaining gap; therefore, as long as the size of the filling joint material 5 is appropriate, the following can be made. Fig.12 The rock-like specimen shown contains multiple filled joint surfaces.

[0079] In this process, the filling joint block 8 can change the size and the roughness parameters of the joint surface, that is, each filling joint material 5 produced is different, so as to prepare a rock-like specimen containing multiple different filling joint surfaces.

[0080] Since the placement position of the filling joint material 5 is controlled by the device scale or by the operator through actual measurement, the placement angle of the filling joint material 5 after the installation protrusion 51 is removed can also be arbitrarily selected, and the following can be made: Fig.12 The rock-like specimen shown contains filled joint planes at multiple angles.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
