[0030] An annular mounting groove 23 is formed on the top of the base 21 , and a sealing ring 24 is installed in the annular mounting groove 23 .

[0031] Furthermore, a sealing ring 24 is provided between the bottom plate 37 and the base 21 to enhance the sealing between the bottom plate 37 and the base 21 and prevent water leakage.

[0036] Working principle: When in use, the cement-stabilized gravel test block is installed in the cylinder 36. A sealing coating is applied between the cement-stabilized gravel test block and the inner wall of the cylinder 36 to prevent water leakage between the cement-stabilized gravel test block and the cylinder 36; after the cement-stabilized gravel test block is installed, the entire test mold 3 is placed on the base 21, and the positioning rod 38 at the bottom of the bottom plate 37 is inserted into the positioning hole 22 to prevent relative sliding between the bottom plate 37 and the base 21. At the same time, a sealing ring 24 is provided between the bottom plate 37 and the base 21 to enhance the sealing between the bottom plate 37 and the base 21 to prevent water leakage; after the test mold 3 is installed on the upper part of the base 21, The hydraulic cylinder 16 drives the lifting plate 11 to move downward, and the lifting plate 11 pushes the spring 13 to move downward, and the spring 13 pushes the limit plate 14 to move downward, and the limit plate 14 drives the lifting rod 15 to move downward, and the lifting rod 15 drives the pressing plate 18 to move downward, so that the circular through hole 17 is sleeved on the outside of the cylinder 36. At the same time, the pressing plate 18 is pressed on the upper part of the bottom plate 37, so that the bottom plate 37 and the base 21 are closely fitted. At the same time, the use of the sealing ring 24 is used to achieve the sealing of the bottom plate 37 and the base 21. After the pressing plate 18 moves down and contacts the bottom plate 37, the hydraulic cylinder 16 can still drive the lifting plate 11 to continue to move downward for a small distance. The lifting plate 11 is compressed on the spring 13, and the spring 13 generates continuous pressure on the limit plate 14. The limit plate 14 transmits the pressure to the pressure plate 18 through the lifting rod 15, so that the pressure plate 18 generates continuous pressure on the bottom plate 37, and then the bottom plate 37 generates continuous pressure on the base 21, preventing the bottom plate 37 from fitting loosely with the base 21. At the same time, the spring 13 also plays a buffering role to prevent the pressure plate 18 from being crushed when the pressure of the hydraulic cylinder 16 is too large. Finally, the anti-seepage tester 2 is started, and the anti-seepage tester 2 injects water into the inner circle of the base 21 to observe the top of the cement stabilized gravel test block in the cylinder 36. Whether there is water seepage; after the inspection is completed, the hydraulic cylinder 16 pushes the lifting plate 11 to move upward, the lifting plate 11 pushes the limit plate 12 to move upward, and the limit plate 12 drives the crimping plate 18 to move upward through the lifting rod 15; when the crimping plate 18 moves to the top of the test mold 3, the test mold 3 is removed from the base 21, and then the cross bar 31 is rotated, and the cross bar 31 drives the screw rod 33 to rotate, so that the screw rod 33 moves in the direction of the cement-stabilized gravel test block, and the screw rod 33 drives the circular plate 35 to move in the direction of the cement-stabilized gravel test block, so that the circular plate 35 pushes the cement-stabilized gravel test block out of the cylinder 36, making the demoulding of the cement-stabilized gravel test block more convenient and quick.
