[0044] The main frame 11 of the flat push plate 19 has protrusions, and square holes are opened inside the protrusions. The bottoms on both sides of the main frame 11 of the flat push plate are welded with the first strip steel 12 and the second strip. Steel 13.

[0045] The material box 18 is composed of five steel plates, a first side plate 1, a second side plate 2, a third side plate 3, a fourth side plate 4 and a bottom plate 5. The adjacent side plates are fastened by bolts. 10 is connected, the bottom plate 5 is drilled with screw holes, and the bottoms of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 are respectively welded to the first angle steel 6, the second angle steel 7, and the third angle steel 8. The fourth angle steel 9, which is respectively welded to the first angle steel 6, the second angle steel 7, the third angle steel 8, and the fourth angle steel 9. The holes corresponding to the screw holes on the bottom plate 5, the first side plate 1, the second The side plate 2, the third side plate 3, and the fourth side plate 4 are respectively connected to the bottom plate 5 by fastening bolts 10, and the top of the first side plate 1 and the second side plate 2 of the material box 18 are respectively provided with two screw holes.

[0046] The T-shaped frame 20 is an inverted "T"-shaped frame, which is composed of a special bolt 14 and a third strip plate 15. The cross section of the special bolt 14 is a square with rounded corners.

[0047] The method of laying a variety of similar materials uniformly layer by layer is used to obtain the multi-layered model material block 17, and multiple thin layers of material are obtained by sliding the flat push plate 19 for multiple times, which are placed under a pressure testing machine and pre-compressed. Obtain the corresponding multi-layer model material block 17.

[0048] There is a raised part in the middle of the main frame 11 of the flat push plate of the flat push plate 19 and a square hole is opened inside the raised part. The bottoms of both sides of the flat push plate main frame 11 are welded with the first strip steel 12 and the second strip. Shaped steel 13.

[0049] The T-shaped frame 20 is an inverted "T"-shaped frame, which is composed of a special bolt 14 and a third strip plate 15. The cross section of the special bolt 14 is a square with rounded corners and only the rounded corners are tapped. The straight side part is not tapped.

[0050] The adjusting nut 16 and the special bolt 14 of the T-shaped frame 20 are marked with scales.

[0051] The material box 18 is composed of a first side plate 1, a second side plate 2, a third side plate 3, a fourth side plate 4, a bottom plate 5 and a number of fastening bolts 10. The adjacent side plates are fastened The bolt 10 is connected. A number of screw holes are opened on the bottom plate 5. The bottoms of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 are respectively welded to the first angle steel 6, the second angle steel 7, and the third angle steel 8. The fourth angle steel 9, the first angle steel 6, the second angle steel 7, the third angle steel 8, and the fourth angle steel 9 have holes corresponding to the screw holes on the bottom plate 5. The first side plate 1, the second side plate 2, The third side plate 3 and the fourth side plate 4 are respectively connected to the bottom plate 5 by a plurality of fastening bolts 10. Two screw holes are respectively opened on the top of the first side plate 1 and the second side plate 2 of the material box. The material box 18 can be easily moved after screwing in ordinary bolts.

[0052] The three views (front view, top view and left view) of the flat push plate 19 are as follows Figure 5 Shown. There is a raised part in the middle of the main frame of the flat push plate 11 and a square hole is opened inside the raised part, and the side length of the hole is slightly smaller than the width of the special bolt 14 of the T-shaped frame 20. Its function is to ensure that the T-shaped frame 20 is relatively flat. The push plate 19 can only slide with a single degree of freedom in the vertical direction. The bottoms of both sides of the main frame 11 of the flat push plate are welded to the first bar steel 12 and the second bar steel 13. The distance between the outer edges of the first bar steel 12 and the second bar steel 13 is slightly smaller than that of the material box 18 The distance between the inner wall of the side plate 1 and the third side plate 3 is to ensure that the horizontal push plate 19 can only move in a horizontal direction relative to the material box 18, so that the T-shaped frame 20 can only be parallel. The bottom plate 5 of the material box 18 moves smoothly.

[0053] The three views (front view, top view and left view) of the T-shaped frame 20 are as follows Figure 5 As shown, it is an inverted "T"-shaped steel frame composed of special bolts 14 and a third strip plate 15. The special bolt 14 is characterized in that its cross section is a square with rounded corners, with only rounded corners. Partially tapped, but the straight side part is not tapped. The rounded part is tapped to match the adjusting nut 16, and the distance between the two opposite straight sides is slightly smaller than the side length of the square hole in the middle convex part of the main frame 11 of the flat push plate. The purpose is to enable the T-shaped frame 20 to be vertical The height can be adjusted arbitrarily in the straight direction and the T-shaped frame 20 will not rotate during the adjustment process.

[0054] The adjustment nut 16 is marked with a scale on the periphery, and one side of the special bolt 14 of the T-shaped frame 20 is also marked with a scale. The reading method of the scale is the same as that of a common spiral micrometer. The two sets of scales can be used to accurately calculate the readings. The purpose of adjusting the height of the T-shaped frame 20 is to accurately control the thickness of a single layer of material.

[0055] The basic process of using this device to prepare multi-layer model materials is as follows:

[0056] 1. Assemble related parts

[0057] The first side plate 1, the second side plate 2, the third side plate 3, the fourth side plate 4 and the bottom plate 5 of the material box 18 are assembled, and the corresponding fastening bolts 10 are assembled in place. The height of the T-shaped frame 20 is pre-adjusted by turning the adjusting nut 16.

[0058] 2. Lay a thin layer of similar materials

[0059] Similar materials are added in the order from bottom to top, and the quality of the added materials is determined by the thickness of the single layer of the material. First, the similar material at the bottom of the model material block 17 is laid, and the similar material powder of the corresponding mass is weighed out and poured into the material box 18.

[0060] After a single layer of similar materials is added to the material box 18, a thin layer of uniform thickness cannot be formed immediately. You can use a brush or other tools to spread the material as evenly as possible. Place the assembled flat push plate 19 and T-shaped frame 20 on the material box 18, and turn the adjusting nut 16 to adjust the bottom end of the T-shaped frame to a proper height. Then push the flat push plate 19 to drive the T-shaped frame 20 to spread the similar material into a thin layer of uniform thickness.

[0061] Remove the flat push plate 19 and turn the adjusting nut 16 to adjust the T-shaped frame 20 to the desired height. The thickness of the single layer of material should be equal to the reading of the T-shaped frame 20 after adjustment minus the degree before adjustment. Add a second layer of similar material, and lay a second layer of similar material in a similar way to the first layer of material.

[0062] Repeat the operation until the last layer of similar materials has been laid.

[0063] 3. Pre-compression molding

[0064] Place the material box 18 on the pressure testing machine, and then place a large-thickness rectangular steel plate on top of the multilayer material, the purpose of which is to make the material receive uniform pressure during the compression process. Then, according to the test requirements, pre-compress the multi-layer materials in the material box 18 for a certain period of time. After the pre-compression molding, the first side plate 1, the second side plate 2, the third side plate 3 and the first side plate of the material box 18 are removed. Four side plates 4 can be formed as Figure 7 The block 17 of multi-interlayer model material is shown.

[0065] Then use the model material block 17 to carry out corresponding rock and soil mechanics tests.
