The bottom ends of the support columns 4 are fixedly connected to the top of the strength test bench 1. In the middle of the top of the fixed plate 5, a hydraulic telescopic rod 31 is fixedly installed. The telescopic end of the hydraulic telescopic rod 31 extends below the fixed plate 5 and is fixedly connected to the middle of the top of the support plate 32. On both sides of the top of the detection plate 34, there are fixed connection guide rods 35. The outer walls of the guide rods 35 are slidably sleeved inside the fixed plate 5. On the left side of the top of the strength test bench 1, a display 36 is fixedly installed. The pressure sensor 33 is signal-connected to the display 36.

[0022] In this embodiment, through the setting of the test collection cover 21, it is convenient to place the soil to be detected. Through the setting of the support columns 4 and the fixed plate 5, it is convenient to support the hydraulic telescopic rod 31. And through the setting of the hydraulic telescopic rod 31, it is convenient to drive the support plate 32, the pressure sensor 33 and the detection plate 34 to move. At the same time, by using the setting of the guide rods 35, it is convenient to vertically guide the detection plate 34. By moving the detection plate 34 down into the test collection cover 21 to press the soil block, it is convenient to test the compressive strength of the soil block.

[0023] Embodiment Two:

[0024] As Figures 1 - 3As shown in the figure, protective grooves 29 are formed on both sides of the bottom of the inner wall of the test protective cover 2. A top block 28 is movably sleeved inside the protective groove 29. Limiting grooves 211 adapted to the outer wall of the top block 28 are formed on both sides of the bottom of the test collection cover 21. The limiting grooves 211 are located above the top block 28. An installation plate 23 is provided below the strength test bench 1. Straight rods 22 are fixedly connected to both sides of the top of the installation plate 23. The top ends of the straight rods 22 are fixedly connected to the bottom of the strength test bench 1. The inside of a push plate 26 is slidably sleeved on the outer wall of the straight rod 22. A motor 24 is fixedly installed in the middle of the bottom of the installation plate 23. The output end of the motor 24 extends above the installation plate 23 and is fixedly connected to a lead screw 25. The top end of the lead screw 25 is rotatably connected to the middle of the bottom of the strength test bench 1. The middle of the push plate 26 is threadedly sleeved on the outer wall of the lead screw 25. Positioning grooves 212 are formed on both sides of the bottom of the inner wall of the test protective cover 2. A rubber pad 213 is fixedly connected to the bottom of the inner cavity of the positioning groove 212. A magnetic sheet 214 is fixedly connected to the top of the rubber pad 213. Iron sheets 215 are fixedly connected to both sides of the bottom of the test collection cover 21. The outer walls of the iron sheets 215 are movably inserted into the positioning grooves 212. The bottom of the iron sheets 215 is magnetically connected to the top of the magnetic sheet 214.

[0025] In this embodiment, by inserting the iron sheets 215 into the positioning grooves 212 and magnetically adsorbing them together with the magnetic sheets 214, it is convenient to increase the stability of the test collection cover 21 inside the test protective cover 2. Through the arrangement of the motor 24 and the lead screw 25, it is convenient to drive the push plate 26 to move on the outer wall of the straight rod 22. The push plate 26 drives the top block 28 to move through a top rod 27, and can jack up the test collection cover 21 upward, facilitating the ejection of the test collection cover 21 from the inside of the test protective cover 2, thereby facilitating the replacement of the test collection cover 21.

[0026] In summary, as Figures 1 - 3As shown in the figure, for this soil structure strength test device, during use, first place the soil block to be tested inside the test collection cover 21. At this time, the telescopic end of the hydraulic telescopic rod 31 drives the support plate 32, the pressure sensor 33, and the detection plate 34 to move downward. The detection plate 34 drives the guide rod 35 to move vertically downward inside the fixed plate 5, and the detection plate 34 can be moved to the inside of the test collection cover 21 to apply pressure to the soil block to detect the compressive strength of the soil block. At this time, the pressure sensor 33 is used to detect the pressure during pressing, and the detected pressure data is transmitted to the display 36, facilitating the staff to understand the pressure of the soil block during the strength test through the display 36. At this time, if the soil block splashes and breaks, the test collection cover 21 is used for protection and to collect the broken soil blocks. After the strength test of the soil block, the telescopic end of the hydraulic telescopic rod 31 contracts and drives the detection plate 34 to move upward for resetting in the same way. At this time, the motor 24 drives the lead screw 25 to rotate, and the lead screw 25 drives the push plate 26 to move vertically upward on the outer wall of the straight rod 22. At the same time, the push plate 26 drives the ejector rod 27 and the ejector block 28 to move, inserts the ejector block 28 into the limit groove 211 at the bottom of the test collection cover 21, and ejects the test collection cover 21 from the inside of the test protection cover 2. At this time, the staff collects the test collection cover 21, then sleeks the limit groove 211 at the bottom of the new test collection cover 21 over the outside of the ejector block 28, and uses the motor 24 to drive the lead screw 25 to rotate in the reverse direction and drives the ejector rod 27 and the ejector block 28 to move downward for resetting in the same way. At this time, the test collection cover 21 moves downward to the inside of the test protection cover 2, and the iron sheet 215 at the bottom of the test collection cover 21 is inserted into the positioning groove 212 and magnetically adsorbed with the magnetic sheet 214, thus facilitating the replacement of the test collection cover 21 and facilitating the subsequent work of the test device for the soil strength test.
