[0027] 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.

[0028] Example 1: Please refer to Figures 1-5Existing permeability testing instruments require placing a test block inside an iron ring during use. However, the test block and the iron ring often do not fit tightly, leading to water seepage from the edges of the iron ring and the test block during subsequent permeability testing. Furthermore, simply coating the test block with wax to prevent seepage is cumbersome. To address this technical problem, this embodiment discloses the following technical content: a leak-proof concrete permeability testing device, including a concrete permeability testing instrument 1. A workbench 2 is mounted on the upper end of the concrete permeability testing instrument 1, and a fixing seat 3 is mounted on the upper end of the workbench 2. The upper end of the fixing seat 3 is used for... The test piece 4 is placed on the outside of the test piece 4. A sealing sleeve component 5 is provided on the outside of the test piece 4. The sealing sleeve component 5 is used to wrap and seal the edge of the test piece 4. The sealing sleeve component 5 includes a protective steel sleeve 501, a rubber ring 502 and a locking component 503. The protective steel sleeve 501 is located on the side of the test piece 4. The rubber ring 502 is provided on the inside of the protective steel sleeve 501. The protective steel sleeves 501 are fixed to each other by the locking component 503. The protective steel sleeves 501 are symmetrically arranged about the longitudinal central axis of the test piece 4. The locking component 503 that fixes the symmetrically distributed protective steel sleeves 501 to each other is a bolt.

[0029] When concrete test specimen 4 needs to be tested, the test specimen 4 is placed on the fixed base 3. Then, a rubber ring 502 is put on the outside of the test specimen 4, and two protective steel sleeves 501 are placed on the outside of the test specimen 4. The two protective steel sleeves 501 are fixed with bolts, which can achieve the clamping and limiting of the test specimen 4. The setting of the rubber ring 502 improves the sealing between the test specimen 4 and the protective steel sleeves 501, preventing water from seeping out from the gap between them. Then, the power supply of the concrete permeability tester 1 is turned on, the upper and lower limit pointers of the electric contact pressure gauge are adjusted, the water pump is started, the control valve is opened, and water pressure is sent into the specimen. Pay attention to whether there is any seepage at the bottom of the test mold. If there is seepage, the corresponding compression nuts need to be tightened. When pressurized water seeps out from the end face of a specified number of test specimens 4, the test can be stopped. The detection principle of the concrete permeability tester 1 described above is all existing technology. This application is a direct utilization of the concrete permeability tester 1.

[0030] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. The following technical content is disclosed in this example: a positioning hole 504 is provided on the protective steel sleeve 501, and a guide slider 6 is provided on the side of the protective steel sleeve 501. The lower end of the guide slider 6 is located in the connecting groove 7 opened on the fixed base 3, and the end of the positioning screw 8 on the guide slider 6 is screwed into the positioning hole 504 on the side of the protective steel sleeve 501. The lower outer wall of the guide slider 6 and the inner wall of the connecting groove 7 are in contact with each other, and the guide slider 6 can slide in the connecting groove 7. The inner wall of the positioning hole 504 is provided with an internal thread that cooperates with the thread on the surface of the positioning screw 8, and the positioning screw 8 and the guide slider 6 are threadedly connected.

[0031] The positioning screw 8 on the guide slider 6 is screwed into the positioning hole 504 on the side of the protective steel sleeve 501, thereby fixing the guide slider 6 and the protective steel sleeve 501. The movement of the guide slider 6 allows the protective steel sleeve 501 to move synchronously, which facilitates the removal of the test piece 4 placed inside. At the same time, the movement of the left and right protective steel sleeves 501 makes it easy to fix test pieces 4 of different sizes. Since the guide slider 6 and the protective steel sleeve 501 are fixed by the positioning screw 8, by rotating the positioning screw 8, the end of the positioning screw 8 is disengaged from the positioning hole 504 on the side of the protective steel sleeve 501, thereby releasing the fixation of the protective steel sleeve 501 and facilitating the subsequent replacement of the protective steel sleeve 501.
