[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Figures 1-6As shown, this utility model provides a device for making rock mass tunnel models with different cross sections, including a base plate 1, a side mold box mechanism 2 detachably provided on the base plate 1, and a connecting mechanism 3 that works with the base plate 1 on the side mold box mechanism 2, a tunnel mold mechanism detachably provided in the middle of the base plate 1, and a limiting mechanism 8 that works with the tunnel mold mechanism on the base plate 1.
[0022] The side mold box mechanism 2 includes a first side mold plate 21 and a second side mold plate 22, both of which can be detachably connected to the base plate 1.

Both ends of the first side mold plate 21 are provided with L-shaped grooves 23, and the L-shaped plate 31 can be slidably inserted into the L-shaped grooves 23. The outer diameter of the L-shaped plate 31 is the same as the inner diameter of the L-shaped groove 23, thereby ensuring the stability of the insertion of the first side mold plate 21 and the second side mold plate 22. The connecting rod 32 is slidably inserted into the side mold box. Both ends of plate 1 21 are connected to the connecting rod 32, which can be slidably inserted into the connecting hole 34. The end of the connecting rod 32 is fixedly connected to the handwheel 35, and a spring 36 is fixedly installed on one side of the handwheel 35. The handwheel 35 has a groove 37 for matching use, and the groove 37 has a symmetrical structure. The groove 37 provides convenience for the operation of the handwheel 35. The spring 36 is movably sleeved on the connecting rod 32, and the end of the spring 36 is fixedly connected to the side plate 1 21. The insertion rod 33 is fixedly installed in the middle of the lower end of one side of the side plate 1 21. The bottom plate 1 has insertion holes 11 on both sides, and the insertion rod 33 can be slidably inserted into the insertion holes 11.
[0023] By adopting the above technical solution, hold two side template 1 21 in sequence and insert their corresponding rods 33 completely into the corresponding holes 11 on the base plate 1. Then hold two side template 22 in sequence and insert the L-shaped plates 31 at both ends into the L-shaped grooves 23 on the corresponding sides. Pull the two handwheels 35 on the corresponding sides in opposite directions, which will drive the two connecting rods 32 to move in opposite directions and stretch the two springs 36. When the distance between the two handwheels 35 is moved to the maximum, stop pulling the handwheels 35 and continue to push the side template 22 down until the corresponding L-shaped plate 31 on the side template 22 is completely inserted into the corresponding L-shaped groove 23 and the bottom end of the side template 22 is tightly attached to the base plate 1. Release the two handwheels 35. At this time, the springs 36 will drive the corresponding handwheels 35 and connecting rods 32 to reset, so that the connecting rods 32 can be inserted into the corresponding connecting holes 34, thereby realizing a convenient and stable connection between the side template box mechanism 2 and the base plate 1.
[0024] The limiting mechanism 8 includes a guide block 81 and an insert block 82. The guide block 81 is fixedly connected to the top center of the base plate 1. The insert block 82 can be slidably inserted into the base plate 1, and a screw 83 is fixedly inserted into the insert block 82. The screw 83 can move through the guide block 81, and a nut 84 is threaded onto the screw 83. The tunnel mold mechanism includes tunnel mold one 4, tunnel mold two 5, tunnel mold three 6, and tunnel mold four 7. Each of the tunnel molds has a guide groove 9 and a through hole 91 for cooperation. The guide groove 9 can be slidably fitted onto the guide block 81, and the screw 83 can move through the through hole 91. A slot 12 is opened at the bottom center of the base plate 1, and the insert block... 82 can be slidably inserted into the slot 12. The outer diameter of the insert 82 is the same as the inner diameter of the slot 12. The outer diameter of the guide block 81 is the same as the inner diameter of the guide groove 9, thus ensuring the stability of the insertion point. The bottom plate 1 and the guide block 81 are connected by a through hole 13 in the middle, which is connected to the slot 12. The screw 83 can move through the through hole 13. The raw materials of the model material include gypsum, cement and quartz sand. The raw materials are as follows by weight: gypsum accounts for 40% of the binder, cement accounts for 60% of the binder, and quartz sand accounts for 35% of the binder. In addition, the quartz sand is 70-110 mesh, the cement is 525 cement powder, and the gypsum is GRG special high-strength gypsum powder.
[0025] By adopting the above technical solution, the screw 83 is passed through the through hole 13 and the insert block 82 is fully inserted into the slot 12. Then, the tunnel mold 1 4, tunnel mold 2 5, tunnel mold 3 6 and tunnel mold 4 7 are sequentially placed on the screw 83 and the guide block 81 is fully inserted into the corresponding guide groove 9. Finally, the nut 84 is used to fix it.
[0026] Working principle: In use, hold the two side templates 1 21 in sequence and insert the corresponding rods 33 into the corresponding holes 11 on the base plate 1. Then hold the two side templates 22 in sequence and insert the L-shaped plates 31 at both ends into the L-shaped grooves 23 on the corresponding sides. Then pull the two handwheels 35 on the corresponding sides in reverse motion, which will drive the two connecting rods 32 to move in reverse motion and stretch the two springs 36. When the distance between the two handwheels 35 is moved to the maximum, stop pulling the handwheels 35 and continue to push the side template 2 22 down until the corresponding L-shaped plate 31 on the side template 2 22 is fully inserted into the corresponding L-shaped groove 23 and the bottom end of the side template 2 22 is tightly attached to the base plate 1. Then release the two handwheels 35. At this time, the springs 36 will drive the corresponding handwheels 35 and connecting rods 32 to reset, so that the connecting rods 32 can be inserted into the corresponding connecting holes 34, thereby realizing the convenient and stable connection between the side template box mechanism 2 and the base plate 1.
[0027] Next, screw 83 is passed through hole 13 and insert block 82 is fully inserted into slot 12. Then, tunnel mold 1 4, tunnel mold 2 5, tunnel mold 3 6 and tunnel mold 4 7 are sequentially fitted onto screw 83 and guide block 81 is fully inserted into corresponding guide groove 9. Then, nut 84 is used to fix them. After tunnel mold 1 4, tunnel mold 2 5, tunnel mold 3 6 and tunnel mold 4 7 are fixed, the material needs to be poured into the assembled mold. When pouring, it is necessary to pour along the joint protrusion to ensure the integrity of the joint part of the sample. Then, the sample in the mold is fully vibrated to avoid air holes in the sample, thus ensuring the integrity of the sample. After the tunnel model solidifies and forms, the mold is disassembled in the reverse order of mold installation, and the formed tunnel model sample can be taken out quickly and without obstacles.
