Description

Technical Field

[0001] The present invention relates to the technical field of similarity model making, and in particular to a device and method for making a sawtooth fault similarity model. Background Art

[0002] Rock burst has become the number one disaster in my country's coal mines. Rock burst in coal mines can generally be divided into three basic types: coal compression type, roof fracture type and fault slip type. Among them, fault slip type is the most common and the most harmful. Fault slip rock burst refers to the phenomenon that the fault slips due to mining activities releases energy, and the energy is transmitted to the tunnel in the form of vibration waves, causing large-scale dynamic damage to the tunnel. In recent years, many major accidents caused by fault slip rock burst have occurred, with severe social impacts.

[0003] Similarity simulation is an indispensable and important research method in the study of the mechanism of fault slip type rock burst. Fault slip type rock burst simulation mainly simulates the rock structure fracture caused by fault slip process in the laboratory (such as shear fracture of fault surface serrated structure), thereby generating stress waves inside the model, and the stress waves are transmitted to the tunnel surface to cause tunnel impact. During the laboratory test, the model is divided into two parts: static zone model and dynamic zone model, and the tunnel is arranged in the static zone model. The dynamic zone model is used to move up and down in the loading bin of the test system so that the static zone fault surface serrated fracture occurs, causing stress waves to be transmitted to the tunnel surface.

[0004] At present, the static zone model is generally set to water glass material, and the dynamic zone model is set to concrete material. In the process of making the model, the water glass material reacts chemically with other substances to precipitate internal moisture, causing the model to shrink violently. In the process of making a model similar to a sawtooth fault surface, this type of material is in contact with the sawtooth partition. In the later shrinkage process, due to the obstruction of the fault partition, the fault serrations are pulled apart at the root, affecting the model preparation effect. Summary of the invention

[0005] The present invention provides a device and method for making a sawtooth fault similar model. The device for making a sawtooth fault similar model can effectively prevent the fault surface sawteeth from being sheared off due to material shrinkage, thereby improving the success rate of similar model preparation.

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Combine the following Figure 1-Figure 5 A device for making a sawtooth fault similarity model provided by an embodiment of the present invention is described, comprising a box body 1 and a partition assembly 2, wherein: The box body 1 has a cavity and a pouring port communicated with the cavity.

[0025] The partition assembly 2 can be removably arranged in the cavity and divides the cavity into a first chamber 11 and a second chamber 12. A serrated structure is provided on the side of the partition assembly 2 facing the first chamber 11 so that a serrated fault surface is formed on the side of the quiet zone model a in the first chamber 11 facing the partition assembly 2.

[0026] In the present invention, by setting the partition assembly 2 in a detachable form, during the production process of a large-size sawtooth fault similar model, the partition assembly 2 can be removed after the static zone model a is initially formed and before a large amount of water is precipitated and shrunk, and then the static zone model a material is allowed to shrink and take shape. This can effectively avoid the situation where the sawtooth section layer is broken at the root due to the obstruction of the partition assembly 2 when the static zone model a material shrinks, thereby improving the success rate of similar model preparation.

[0027] In the related art, when preparing a sawtooth fault similar model, the water glass material of the static zone model a reacts chemically with other substances during the model making process to precipitate internal moisture, resulting in a drastic shrinkage phenomenon in the static zone model a. The material of the static zone model a is in contact with the partition, and during the shrinkage process, the sawtooth on the sawtooth fault surface of the static zone model a is broken at the root due to the obstruction of the partition, thereby affecting the effect of model preparation.

[0028] In the embodiment of the present invention, the partition assembly 2 is detachably installed in the cavity, and the cavity is divided into a first chamber 11 and a second chamber 12 by the partition assembly 2. The sawtooth structure of the partition assembly 2 is used to form the sawtooth fault surface of the static zone model a in the first chamber 11. The setting of the sawtooth structure ensures the formation of an accurate sawtooth fault surface, and the independent forming of the static zone model a and the dynamic zone model b is ensured by the chamber separation. The detachable characteristic of the partition assembly 2 avoids stress concentration during the contraction of the static zone model a, and solves the problem of the sawtooth root fracture of the static zone model a due to the obstruction of the fixed partition during the contraction process, thereby ensuring the effect of similar model preparation and improving the success rate.

[0029] Specifically, the sawtooth structure can be selected from triangles with different angles, sawtooths with different depths, and arrangements with different spacings, and can be designed according to the required model.

[0030] In some embodiments, the serrated fault surface of the static area model a is enclosed with the box body 1 to form a molding cavity 13 after the partition assembly 2 is removed, and the molding cavity 13 is used to mold the dynamic area model b.

[0031] In the present invention, the sawtooth fault surface is used as a boundary surface of the forming cavity 13. After the partition assembly 2 is removed, the sawtooth fault surface of the static zone model a is formed. The sawtooth fault surface and the box body 1 are enclosed to form a forming cavity 13 for casting the dynamic zone model b. The dynamic zone model b is cast in the forming cavity 13. The sawtooth fault surface of the static zone model a is enclosed with the box body 1 to form the forming cavity 13, which ensures the precise matching of the dynamic zone model b and the static zone model a, simplifies the manufacturing process of the dynamic zone model b, and ensures the matching degree of the sawtooth structure between the dynamic and static zone models a.

[0032] In the related art, in the current similar model preparation process, the static area model a and the dynamic area model b are simultaneously prepared, and the dynamic area model b and the static area model a are respectively cast and formed on both sides of the partition, and finally the mold is disassembled to obtain a similar model. The side of the dynamic area model b facing the static area model a is shaped through the partition, and it is difficult to ensure the degree of matching between the dynamic area model b and the static area model a.

[0033] In this embodiment, by adopting a design that the partition assembly 2 can be disassembled separately, the static zone model a can be cast first. When the static zone model a is initially formed and before a large amount of water is precipitated, the partition assembly 2 is removed, and the static zone model a is waited for to precipitate water and shrink to form, thereby ensuring the integrity of the sawtooth fault surface structure of the static zone model a. Then, the sawtooth fault surface of the static zone model a is used as a side surface of the dynamic zone model b to cast the dynamic zone model b, thereby ensuring that the dynamic zone model b and the static zone model a are precisely fitted at the sawtooth fault surface, thereby improving the matching degree of the contact surface between the dynamic zone model b and the static zone model a.

[0034] In some embodiments, the sawtooth structure extends along the first direction, and at least a portion of the partition assembly 2 can slide along the first direction so that after the partition assembly 2 is removed, a sawtooth fault surface is formed on the side of the quiet zone model a facing the second chamber 12.

[0035] In the present invention, the sawtooth structure is arranged to extend along the first direction, and after the quiet zone model a is initially formed, the partition assembly 2 is slid and removed along the first direction, thereby forming a complete sawtooth fault surface of the quiet zone model a. By setting the sliding structure in the first direction, the partition assembly 2 is smoothly removed, the integrity of the sawtooth structure after the quiet zone model a is initially formed is ensured, and damage to the quiet zone model a is prevented during the removal process.

[0036] Specifically, the serrated structure on the partition assembly 2 is generally arranged horizontally to form a plurality of serrated structures extending horizontally on the serrated fault surface of the quiet zone model a. By disassembling at least part of the partition assembly 2 by sliding in the horizontal direction, it can be ensured that the serrated structure on the partition assembly 2 will not damage the serrated fault surface on the quiet zone model a, thereby ensuring the integrity of the serrated fault surface.

[0037] Of course, the serrated structure on the partition assembly 2 may not be arranged in the horizontal direction, but may be arranged in the vertical direction or at an angle to the horizontal direction according to the actual design requirements of similar models. As long as the sliding and disassembly direction of the partition assembly 2 is consistent with the extension direction of the serrated structure, the integrity of the serrated fault surface on the quiet zone model a can be guaranteed.

[0038] In a specific embodiment, the entire partition assembly 2 can slide along the first direction, so that the partition assembly 2 can be slid out of the box body 1 as a whole to the outside of the box body 1, thereby ensuring that the serrated fault surface of the quiet zone model a is not damaged when the partition assembly 2 is removed.

[0039] In another specific embodiment, the partition assembly 2 can be configured in the form of multiple pieces, wherein the portion directly connected to the box body 1 is configured to slide along a first direction to complete disassembly, and the portion not directly connected to the box body 1 can be selected to move toward the second chamber 12 to complete disassembly.

[0040] Optionally, after the quiet zone model a is initially formed and before a large amount of water is precipitated, the partition assembly 2 can be moved toward the second chamber 12 to complete the disassembly. However, since the quiet zone model a is not completely formed in this disassembly method, adhesion will form between the partition and the quiet zone model a, thereby affecting the integrity of the serrated fault surface of the quiet zone model a.

[0041] In some embodiments, the box body 1 includes a first side panel 14 and a second side panel 15, and the first side panel 14 and the second side panel 15 are arranged relatively to each other along a first direction; the partition assembly 2 includes: a first partition 21, which is detachably connected to the first side panel 14; a second partition 22, which is detachably connected to the second side panel 15; and a connecting member for connecting the first partition 21 and the second partition 22.

[0042] Specifically, the box body 1 includes five steel plates, namely a bottom steel plate and four side steel plates. The top is provided with an opening as a pouring port. The bottom steel plate is a flat plate. Different numbers of ribs are provided on the outside of the four side steel plates to improve the bending rigidity of the plane. The connection between the bottom steel plate and the side steel plates can be a "keyway" connection. Different numbers of circular groove openings are arranged around the bottom steel plate. The corresponding positions of the bottom of the side steel plates are provided with raised keys. During the installation process, the surrounding steel plates are inserted into the corresponding circular grooves of the bottom plate according to the raised positions, and wedges are used to fix and tension the surroundings. The first side plate 14 and the second side plate 15 are two of the side steel plates.

[0043] In the present invention, the first side plate 14 and the second side plate 15 are arranged relatively to each other along the first direction, and the first partition plate 21 and the second partition plate 22 are connected to the first side plate 14 and the second side plate 15 respectively. When disassembling, the first partition plate 21 slides along the first direction to complete the disassembly with the first side plate 14, and the second partition plate 22 slides along the first direction to complete the disassembly with the second side plate 15. The split design facilitates assembly and disassembly, while ensuring the integrity of the serrated fault surface of the quiet zone model a. The first partition plate 21 and the second partition plate 22 are connected by a connecting piece to improve the structural stability.

[0044] In a specific embodiment, a first socket extending along a first direction is provided on the first side panel 14, and a first plug board 211 plugged into the first socket is provided on the first partition panel 21; and / or a second socket extending along the first direction is provided on the second side panel 15, and a second plug board 221 plugged into the second socket is provided on the second partition panel 22.

[0045] like Figure 2 As shown, in the present invention, the first plug hole on the first side plate 14 extends along the first direction, and the first plug plate 211 on the first partition plate 21 is plugged and matched with the first plug hole. Specifically, a wedge socket 212 is also provided on the first plug plate 211. When the first plug plate 211 passes through the first plug hole from the box body 1, the wedge is driven into the wedge socket to complete the reliable connection between the first partition plate 21 and the first side plate 14. When the first partition plate 21 is disassembled later, the wedge is first removed, and then the first partition plate 21 is pushed along the first direction, so that the first plug plate 211 can be withdrawn from the first plug hole, and the sawtooth fault surface of the quiet zone model a will not be damaged when the first partition plate 21 is disassembled, thereby ensuring the molding effect and integrity of the sawtooth fault surface.

[0046] Similarly, the second plug hole on the second side plate 15 extends along the first direction, and the second plug plate 221 on the second partition plate 22 is plugged and matched with the second plug hole. Specifically, a wedge socket 212 is also provided on the second plug plate 221. When the second plug plate 221 passes through the second plug hole from the box body 1, the wedge is driven into the wedge socket 212 to complete the reliable connection between the second partition plate 22 and the second side plate 15. When the second partition plate 22 is disassembled later, the wedge is first removed, and then the second partition plate 22 is pushed along the first direction, so that the second plug plate 221 can be withdrawn from the second plug hole, and the sawtooth fault surface of the quiet zone model a will not be damaged when the second partition plate 22 is disassembled, thereby ensuring the molding effect and integrity of the sawtooth fault surface.

[0047] In some embodiments, the connecting member includes a connecting beam 23 , which is detachably connected to the first partition plate 21 and the second partition plate 22 , and the connecting beam 23 is located in the second chamber 12 .

[0048] In the present invention, the design of the detachable connection of the connecting beam 23 ensures the stability and detachability of the overall structure of the partition assembly 2; the design of the connecting beam 23 being located in the second cavity avoids direct contact with the quiet zone model a, reducing the impact on the molding of the quiet zone model a; through the setting of the connecting beam 23, the connection strength between the first partition 21 and the second partition 22 is improved, and the detachable connection method facilitates the maintenance and replacement of the device.

[0049] Specifically, the connecting crossbeam 23 can be a transverse supporting member made of metal material, and can be connected to the first partition 21 and the second partition 22 by a detachable connection form such as bolt connection and snap connection. By arranging the connecting crossbeam 23 in the second cavity, avoiding the casting area of ​​the quiet zone model a, the forming of the sawtooth fault surface of the quiet zone model a will not be affected.

[0050] In a specific embodiment, the partition assembly 2 includes a first partition 21, a second partition 22 and a connecting beam 23. One end of the first partition 21 is connected to the first side plate 14, and one end of the second partition 22 is connected to the second side plate 15. The first partition 21 and the second partition 22 are detachably connected, and then the first partition 21 and the second partition 22 are reinforced by the connecting beam 23 to form a complete partition structure.

[0051] In some embodiments, the connecting member further includes at least one third partition 24 , at least one third partition 24 is detachably connected to the first partition 21 and the second partition 22 at both ends along the first direction, and at least one third partition 24 is detachably connected to the connecting beam 23 .

[0052] In the present invention, the third partition 24 is added to provide multi-point support, which significantly enhances the overall rigidity of the partition assembly 2. The detachable design of the third partition 24 maintains the flexibility of the overall structure, and forms a stable frame structure by cooperating with the connecting beam 23. The multi-point connection improves the anti-deformation ability of the partition assembly 2 during use, which facilitates the adjustment of the support position and quantity according to actual needs.

[0053] Specifically, one or more third partitions 24 may be provided, and connected to the first partition 21 and the second partition 22 at both ends along the first direction; a sealing strip or a sealing gasket may be provided as needed to ensure the sealing of the connection between the first partition 21, the second partition 22, and the third partition 24.

[0054] In the embodiment of the present invention, by providing the third partition 24, the preparation size of similar models can be effectively increased, and by splitting the partition assembly 2 into multiple split structures, disassembly and assembly are facilitated. Moreover, when disassembling the partition assembly 2, the connecting beam 23 can be disassembled first, and then the third partition 24 that is not in direct contact with the box body 1 can be disassembled, and the disassembly direction can be directly moved toward the second chamber 12. After the third partition 24 is disassembled, a movable space is reserved for the sliding of the first partition 21 and the second partition 22, thereby facilitating the sliding removal of the first partition 21 and the second partition 22. The length of the third partition 24 along the first direction is greater than the sum of the lengths of the first plug plate 211 and the second plug plate 221. When the third partition 24 is removed, space can be reserved for the sliding of the first partition 21 and the second partition 22.

[0055] In a specific embodiment, the number of the third partition 24 is one, and the entire partition assembly 2 includes a first partition 21 plugged into the first side plate 14, a second partition 22 plugged into the second side plate 15, a third partition 24 connecting the first partition 21 and the second partition 22, and a connecting beam 23, and the connecting beam 23 is provided with different numbers of bolt holes, and the first partition 21, the second partition 22 and the third partition 24 can be connected as a whole by bolts 25.

[0056] Specifically, the first partition plate 21, the second partition plate 22 and the third partition plate 24 are all provided with a sawtooth structure on one side facing the first chamber 11, and the continuity of the sawtooth structure is ensured by positioning.

[0057] In some embodiments, an ejection mechanism 3 is further included. The ejection mechanism 3 is located outside the box body 1 and has a retractable ejection portion for ejecting the first plug board 211 in the first plug hole and the second plug board 221 in the second plug hole along a first direction.

[0058] In the present invention, the setting of the ejection mechanism 3 realizes the active separation of the first partition 21 and the second partition 22, which solves the inconvenience of traditional manual removal. The abutment design of the ejection mechanism 3 and the first partition 21 ensures the smooth and controllable separation process, reduces the risk of model damage caused by manual operation errors, improves the demolding efficiency and operational safety, and facilitates the control of the demolding force to avoid damage to the quiet zone model a.

[0059] like Figure 3-5 As shown, specifically, the ejection mechanism 3 includes a body 31, a roller 32 is provided at the bottom of the body 31, and the body 31 can move freely on the ground. The body 31 is provided with a telescopic unit 33 that can be extended in the horizontal direction, and the telescopic unit 33 has an ejection portion 331. By moving the body 31 to the outside of the first side plate 14 and aligning the ejection portion 331 with the first plug plate 211 of the first partition 21, and then pushing the first partition 21 into the box body 1 through the ejection portion 331 extending, the first partition 21 is slidably separated from the first side plate 14. By moving the body 31 to the outside of the second side plate 15 and aligning the ejection portion 331 with the second plug plate 221 of the second partition 22, and then pushing the second partition 22 into the box body 1 through the ejection portion 331 extending, the second partition 22 is slidably separated from the second side plate 15. The force of pushing out the first partition 21 and the second partition 22 can be precisely controlled, and the direction of pushing out the first partition 21 and the second partition 22 can be ensured, further ensuring that the serrated fault surface that is not fully positioned is damaged when the first partition 21 and the second partition 22 are slid and removed.

[0060] Furthermore, a reaction frame 34 is provided on the body 31, and bolt holes are provided on the reaction frame 34 for connecting and fixing with the first side plate 14 and the second side plate 15 of the box body 1, so that a connection relationship is established between the body 31 and the box body 1, thereby ensuring that the ejection part 331 can stably push out the first partition 21 or the second partition 22 when it is extended.

[0061] Furthermore, a lifting unit 35 is also provided on the machine body 31, and the telescopic unit 33 and the reaction frame 34 are both provided on the lifting unit 35. The telescopic unit 33 and the reaction frame 34 can be adjusted by the lifting unit 35 to ensure that the force application point of the telescopic unit 33 can be aligned with the first plug plate 211 and the second plug plate 221 to ensure the stability of the first partition 21 and the second partition 22. At the same time, by providing the lifting unit 35, it can also be applied to boxes 1 of different heights, and the partition assemblies 2 of different heights can be slidably disassembled.

[0062] The device for making similar models of sawtooth faults arranges the partition assembly 2 in a detachable form. During the process of making similar models of large-sized sawtooth faults, the partition assembly 2 can be removed after the initial formation of the quiet zone model a and before a large amount of water is precipitated and shrinks. Then, the material of the quiet zone model a can be waited for to shrink and take shape. This can effectively avoid the situation where the sawtooth section layer is broken at the root due to the obstruction of the partition assembly 2 when the material of the quiet zone model a shrinks, thereby improving the success rate of similar model preparation.

[0063] Combine the following Figure 6-Figure 9 Description The embodiment of the present invention provides a method for making a sawtooth fault similarity model, using the above-mentioned sawtooth fault similarity model making device, the making method includes: S1, mold assembly: install the partition assembly 2 in the box body 1, and divide the cavity of the box body 1 into a first cavity and a second cavity 12; S2, casting of the quiet zone model a: casting the quiet zone model a in the first chamber 11; S3, partition removal: when the quiet zone model a is initially formed, the partition assembly 2 is removed; S4, contraction of quiet zone model a: water is analyzed out of quiet zone model a and shrinks to form; S5, casting of the dynamic area model b: the sawtooth fault surface of the static area model a and the box body 1 are used to enclose a forming cavity 13, and the dynamic area model b is cast in the forming cavity 13. After the dynamic area model b is finalized, the preparation of a similar model is completed.

[0064] In the present invention, by first casting the static zone model a, after the static zone model a is initially formed and has a certain strength, but before it begins to shrink significantly, the partition is selected to be removed, and the removal method adopts sliding disassembly along the extension direction of the sawtooth structure, which will not cause damage to the sawtooth fault surface on the static zone model a, thereby ensuring the integrity of the sawtooth fault surface; after removing the partition, the static zone model a is cured, so that the water in the static zone model a is analyzed out, and when the curing is 3-5 days, the water analysis of the static zone model a is observed, and after a large amount of water is analyzed out, the static zone model a is completely shrunk, the static zone model a is finalized, and the fault surface remains in a sawtooth shape. On this basis, the sawtooth fault surface of the static zone model a is used as one side of the forming cavity 13, and the dynamic zone model b is cast, and the preparation of a similar model is completed after the dynamic zone model b is finalized. By completing the disassembly of the partition assembly 2 when the static zone model a is initially formed, it is prevented that the static zone model a is relatively displaced with the partition assembly 2 when shrinking, thereby preventing the serrated fault surface of the static zone model a from being damaged; by using the serrated fault surface of the static zone model a after being finalized as one side of the casting of the dynamic zone model b, it can be ensured that the dynamic zone model b and the static zone model a are precisely fitted at the serrated fault surface, thereby ensuring the yield and quality of similar models.

[0065] Specifically, Figure 6As shown, when assembling the mold, first fix the front, left and right steel plates of the box body to the bottom plate (insert into the circular groove of the bottom plate and fix with wedges on the outside), then install the three partitions on the front steel plate from the back of the box body (insert the protruding plugs of the partitions into the plug holes of the front steel plate), and fix and tension them with wedges, and fix the three partitions with connecting beams. On this basis, install the steel plate on the back of the box body, and fix the back steel plate and the partition with wedges, and the mold assembly is completed. Figure 7 As shown, when casting the quiet zone model, water glass is cast into the first cavity; Figure 8 As shown, when removing the partition, first remove the connecting beam, then remove the third partition in the middle, and then use the ejection mechanism to slide and remove the first and second partitions on both sides to form a molding cavity. Fig. 9 As shown, when pouring the dynamic area model, concrete is poured into the forming cavity, and the dynamic area model is waited to be formed to obtain a similar model.

[0066] In some embodiments, the quiet zone model a contraction includes: S41. Wrapping the quiet zone model a with an isolation film to isolate the quiet zone model a from the air.

[0067] Specifically, the isolation film can be made of plastic wrap to prevent the quiet zone model a from contacting the air when shrinking, thereby ensuring the later forming effect of the quiet zone model a. Moreover, by wrapping the plastic wrap, the quiet zone model a that is not fully formed can be fixed to prevent the quiet zone model a from deforming toward the second chamber 12 after the partition assembly 2 is removed. Moreover, the plastic wrap can change its shape adaptively with the shrinkage of the quiet zone model a, and will not affect the forming effect of the sawtooth fault surface of the quiet zone model a.
