That is, the hopper 202 can move not only in the up-and-down motion on the second slider 7 along with the up-and-down groove 8, but also in the linear motion on the guide rail 1 along with the second slider 7, thereby realizing the control of the movement of the hopper 202 from a plurality of directions.
Specifically, as shown in fig. 9 to 10, the hopper 202 includes an articulated shaft 10, a fixed bucket piece 11 and a movable bucket piece 12, the movable bucket piece 12 is movably articulated on the fixed bucket piece 11 through the articulated shaft 10, so that the movable bucket piece 12 can deflect around the articulated shaft 10 on the fixed bucket piece 11, in addition, the upper portions of the fixed bucket piece 11 and the movable bucket piece 12 are bent and then mutually enclosed to form a storage cavity 13, the lower portions of the fixed bucket piece 11 and the movable bucket piece 12 are linearly extended and then mutually overlapped to form a normally closed flat clamping nozzle 14, and when in use, the flat clamping nozzle 14 can be driven to open by controlling the movable bucket piece 12 to rotate around the articulated shaft 10. It should be noted that, in this embodiment, the hinge shaft 10 is located inside the material storage chamber 13 and above the flat clamping nozzle 14, so that the upper end of the movable bucket 12 and the flat clamping nozzle 14 are respectively located at the upper side and the lower side of the hinge shaft 10, and thus, as long as the upper end of the movable bucket 12 is pushed and pressed to deflect toward the inside of the material storage chamber 13, the flat plate at the lower end of the movable bucket 12 can be driven to deflect outward, and further the flat clamping nozzle 14 is driven to open, and after the flat clamping nozzle 14 opens, the filling material inside the material storage chamber 13 can fall into the slit downward, so as to implement the operation of filling the fault. In addition, because the lower parts of the fixed bucket piece 11 and the movable bucket piece 12 are overlapped with each other after extending linearly to form a normally closed flat clamping mouth 14, therefore, when the kerf of the simulation model is filled, the hopper 202 can be controlled to descend through the lifting groove 8 of the second lifting structure 201, so that the flat clamping mouth 14 is inserted into the deep part of the kerf in advance, the movable bucket 12 is then manipulated to rotate about the hinge axis 10 to drive the flat jaws 14 to open, properly spread the slits of the phantom with the flat jaws 14 open, meanwhile, the filling material in the storage cavity 13 can fall into the cutting seam through the opened flat clamping nozzle 14 to fill the cutting seam, during the continuous blanking and filling process, the flat clamping nozzle 14 is guided to move transversely and move up and down through the second lifting structure 201 and the guide rail 1 at the same time until the filling material completely fills the whole inside of the cutting seam, so that the dense filling can be ensured.

Based on the above specific solutions, this embodiment further provides a fault making method for the similar model test of the underground engineering, as shown in fig. 1 to 13, which includes the fault making apparatus for the similar model test of the underground engineering, and includes the following steps:

s3, erecting and fixing the fault making device at a proper position on the simulation model according to the direction of the fault marking line;
s4, moving the movable disk saw 3 of the joint cutting device 100 to the end part of the fault marking line, adjusting the saw falling depth of the movable disk saw 3 through the first lifting structure 101, starting the movable disk saw 3, and controlling the movable disk saw 3 to cut a joint on the simulation model along the fault marking line by using the guide rail 1 to cut the joint until the simulation model is cut through to form a fault joint cut;
s5, filling the hopper 202 of the filling device 200 with a filling material, and moving the hopper 202 along the guide rail 1 to the end of the fault-cutting seam;
S6, controlling the hopper 202 to descend through the second lifting structure 201 so that the flat gripper 14 at the bottom of the hopper 202 is inserted into the depth of the fault incision;

s8, adjusting the position and height of the hopper 202 through the guide rail 1 and the second lifting structure 201 until the filling material is filled in the fault cutting seam;
and S9, removing the fault making device.
In step S1, after the simulation model is laid, the model may be demolded after curing to be formed, but it is not necessary to wait for complete curing, otherwise the strength of the model is too high, which increases difficulty in cutting and filling.
In step S2, by making fault marking lines for simulating fault positions on the simulation model in advance, on one hand, it is convenient to pre-position the fault making device according to the track direction of the fault marking lines in step S3, make the guide rail 1 parallel to the fault track line and to pre-correspond the movable disk saw 3 and the flat clamping mouth 14 downwards to the fault marking lines, so as to perform the function of pre-positioning; on the other hand, the movable disc saw 3 can accurately cut a pre-designed fault cutting slit along the fault marking line.
In step S4, the guide rail 1 guides the movable disk saw 3 to move linearly on the phantom so as to ensure that the cut cross-sectional cut is straight, and the first elevation structure 101 adjusts the cutting depth, which is the drop depth of the movable disk saw 3, so as to ensure that the movable disk saw 3 can cut through the phantom to form the cross-sectional cut. Therefore, after the cutting depth of the movable disk saw 3 can be adjusted, the fault making of different sizes can be dealt with, the movable disk saw 3 can be ensured to cut through the simulation model, and the fault making of any size can be realized.
The hopper 202 is moved to the end of the fault-cut in advance in step S5 in preparation for subsequent filling of the fault-cut.
In steps S6 to S8, the hopper 202 is controlled to descend by the second lifting structure 201, so that the flat nozzles 14 are inserted into the deep parts of the fault cuts in advance, then the movable bucket 12 is controlled to rotate around the hinge shaft 10 to drive the flat nozzles 14 to open, the fault cuts of the simulation model are properly opened by the open flat nozzles 14, the internal space of the fault cuts is properly enlarged, meanwhile, the filling material in the storage cavity 13 can fall into the cuts through the open flat nozzles 14, so as to fill the cuts, and then the flat nozzles 14 are guided to move transversely and lift by the second lifting structure 201 and the guide rail 1 until the filling material completely fills the whole cuts, so that the dense filling of the fault cuts can be ensured.
In conclusion, the fault making method for the underground engineering similar model test can realize fault making in any direction and any size, and can ensure that the fault is straight and is densely filled.
