[0002] The impermeability of hydraulic concrete is an important indicator for evaluating its ability to resist water seepage in hydraulic engineering projects. To ensure that concrete structures can effectively prevent water penetration, specialized testing equipment is usually used for testing.

[0003] Existing testing equipment for the impermeability of hydraulic concrete typically involves placing a concrete sample in a testing chamber and then introducing water into the chamber to test the sample. However, since the size of the testing chamber is fixed and cannot be changed, it can only hold concrete samples of the corresponding size and shape, which is not convenient for meeting the testing needs of concrete samples of different sizes and shapes, resulting in low flexibility of use.

[0004] Therefore, a hydraulic concrete impermeability testing device has now been developed that allows for the replacement of different placement frames and sealing caps to meet the testing needs of different concrete samples. Utility Model Content

[0005] To overcome the shortcomings of existing hydraulic concrete permeability testing equipment, such as fixed test chamber size that cannot be changed and can only hold concrete samples of corresponding size and shape, which is not convenient to meet the testing needs of concrete samples of different sizes and shapes and has low flexibility, this utility model provides a hydraulic concrete permeability testing equipment that can replace different placement frames and sealing covers to meet the testing needs of different concrete samples.

[0006] Technical Solution: A device for testing the impermeability of hydraulic concrete includes a base box, casters, a testing box, an opening and closing door, placement frames, mounting blocks, water outlet pipes, air bladders, a water collection frame, valves, fixing components, and a sealing component. Multiple casters are rotatably connected to the lower side of the base box. The testing box is connected to the upper side of the base box. An opening and closing door is snapped onto the front of the testing box. Multiple placement frames are placed at the bottom of the testing box.

Detailed Implementation

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] A device for testing the impermeability of hydraulic concrete, such as Figures 1-5 As shown, the assembly includes a base box 1, casters 2, a testing box 3, an opening / closing door 4, a placement frame 5, a mounting block 6, a water outlet pipe 7, an airbag 8, a water collection frame 9, a valve 10, a fixing component, and a sealing component. Four casters 2 are rotatably connected to the lower side of the base box 1. The testing box 3 is connected to the upper side of the base box 1. The opening / closing door 4 is snapped onto the front of the testing box 3. The opening / closing door 4 has a gripping groove on its right side for easy gripping. The opening / closing door 4 is made of transparent material to facilitate viewing the internal structure. The detection box 3 has three placement frames 5 at its lower part. Each placement frame 5 has a mounting block 6 connected to its lower left and right sides. Each placement frame 5 has a water outlet pipe 7 connected to its lower middle side. Each placement frame 5 has an airbag 8 connected inside it. The detection box 3 has a water collection frame 9 connected to its lower side. The water outlet pipes 7 are all connected to the water collection frame 9. The water collection frame 9 has a valve 10 on its lower side, which is connected to the base box 1. The detection box 3 has a fixing assembly, which includes a lead screw 11 and a fixing bracket 12. The lead screw 11 is rotatably connected to the middle of the detection box 3. The lead screw 11 has a handle on its front side for easy gripping and rotation. The lead screw 11 passes through the base box 1. The fixing bracket 12 is threadedly connected to the rear side of the lead screw 11. The fixing bracket 12 is slidably connected to the detection box 3. Each mounting block 6 engages with the fixing bracket 12. The detection box 3 also has a sealing assembly, which includes an electric push rod 13. The test box 3 is equipped with a connector 14, a connecting frame 15, a fixing screw sleeve 16, a sealing cover 17, and a water inlet pipe 18. The upper side of the test box 3 is connected to the electric push rod 13, and the telescopic end of the electric push rod 13 is connected to the connector 14. The fixing screw sleeve 16 is threaded onto the connector 14. The lower part of the fixing screw sleeve 16 is connected to the connecting frame 15 through damping rotation. The sealing cover 17 is connected to the lower side of the connecting frame 15, and the water inlet pipe 18 is connected to the sealing cover 17.

[0021] When using this invention, firstly, the base box 1 is moved to the hydraulic concrete impermeability testing area using the universal wheels 2. Then, the opening and closing door 4 is removed, and samples are taken from the same piece of concrete. The concrete samples are placed into the placement frame 5, and then the opening and closing door 4 is reset. After the concrete samples are placed in the placement frame 5, the airbag 8 can expand and fit against the concrete samples. Then, the electric actuator 13 is activated to push the connecting frame 15 downward, so that the sealing cover 17 closes with the placement frame 5. Water is then supplied to the water inlet pipe 18, so that the water flows in from the top of the concrete sample, flows out from the bottom of the concrete sample, and flows out from the water outlet pipe 7 and collects in the designated area. In the water collection frame 9, the valve 10 is opened to drain the accumulated water. The permeability coefficient is calculated by measuring the amount of water passing through the sample within a certain time. When different concrete samples need to be tested, the screw 11 can be rotated to move the fixing frame 12 forward and disengage it from the mounting block 6, allowing the placement frame 5 to be replaced. After replacement, the fixing frame 12 is re-engaged with the mounting block 6 to fix the placement frame 5. Then, the fixing screw sleeve 16 is rotated off the connector 14 to replace the sealing cover 17. This allows for the replacement of different placement frames 5 and sealing covers 17 to meet the testing needs of different concrete samples.

[0022] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
