[0002] In water conservancy projects, the impermeability of concrete is one of the important indicators for measuring its quality, which directly affects the durability and safety of water conservancy facilities. With the expansion of the scale of water conservancy projects and the increasing complexity of the construction environment, the requirements for testing the impermeability of concrete are also getting higher and higher.

[0003] A search revealed a Chinese patent disclosure for a concrete impermeability testing device (authorization announcement number CN213364538U), comprising a base plate, with bases fixedly connected to both sides of the bottom end of the base plate, two support plates fixedly connected to the top edge of the top of the base plate, a top plate fixedly connected to the top of the two support plates, a connecting rod fixedly connected to the middle of the top of the top of the top plate, a test cover plate fixedly connected to the bottom end of the connecting rod, an annular protrusion fixedly connected to the bottom edge of the test cover plate, a test platform fixedly installed at the top of the base plate, and a concrete test specimen installed at the middle of the top of the test platform. Although this patented technology can achieve a sealed connection through the annular groove at the top of the concrete test specimen and the annular protrusion at the bottom of the test cover plate, and then apply pressure while the water pump injects water into the annular groove.

[0004] However, the above-mentioned device still has some shortcomings in actual use. The most obvious one is that the concrete impermeability test equipment lacks an important structure for measuring the penetration depth, which results in a lack of data in the impermeability test and thus fails to achieve the best performance of the device. In addition, the above-mentioned impermeability test equipment lacks a water resource recovery structure, which will affect the test environment due to water flowing everywhere.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1-4 A concrete permeability testing device for water conservancy engineering quality inspection includes a workbench 1. A scale 4 is mounted on the top of the workbench 1. Two fixed blocks 5 are fixedly connected to one side of the scale 4. A limit rod 6 is fixedly connected between the two fixed blocks 5. A lifting plate 8 is slidably connected to the outside of the limit rod 6. A spring 7 is sleeved on the outside of the limit rod 6 and above the lifting plate 8. A probe 9 is fixedly connected to one end of the bottom of the lifting plate 8, and a pointer 12 is fixedly connected to the end of the lifting plate 8 away from the probe 9. After the concrete permeability test is completed, the scale 4 can be pushed towards the concrete test specimen through a displacement component. Subsequently, the lifting plate 8 can be pushed downwards along the outer wall of the limit rod 6 by the force of the spring 7, allowing the probe 9 to contact the inner wall of the permeated hole. The operator can then use the scale 4 to measure the permeation depth, providing data for the permeability test and achieving the optimal performance of the device.

[0026] Specifically, the workbench 1 is equipped with a recycling component, which includes a support groove located at the center of the workbench 1. A drain plate 14 is fixedly connected inside the support groove. A water collection tank 3 is placed at the bottom of the workbench 1, below the support groove. The perforated design of the drain plate 14 provides support for the concrete test specimen and facilitates water flow into the water collection tank 3, thereby collecting the water for easy cleaning and reducing the impact of wastewater on the test environment. The bottom of the scale 4 is equipped with a displacement component, which includes components fixedly connected to the workbench 1. The top of the workbench 1 has a slide rail 10, and a slider 11 is slidably connected inside the slide rail 10. Through the cooperation of the slider 11 and the slide rail 10, the scale 4 can be moved to facilitate the measurement of the penetration depth by the staff. The slider 11 is fixedly connected to the outside of the scale 4. The top of the workbench 1 is equipped with a clamping assembly, which includes two support plates 15 fixedly connected to the top of the workbench 1. As the screw 16 is continuously screwed in, it can drive the rubber block to move, thereby achieving the purpose of clamping concrete test pieces of different sizes. The support plates 15 are all threadedly connected with screws 16.

[0027] Specifically, a concrete test specimen is placed on top of the drain plate 14, and rubber blocks are fixedly connected to the near ends of the two screws 16 to prevent damage to the concrete test specimen due to excessive clamping force. A metering pump 13 is fixedly installed on top of the U-shaped frame 2, and a nozzle 17 is fixedly connected to the output end of the metering pump 13. The input end of the metering pump 13 can be connected to an external drainage pipe, and water can be sprayed out through the nozzle 17. Support feet are fixedly connected to both ends of the bottom of the workbench 1, and a handle is fixedly connected to the top of the lifting plate 8.

[0028] Working principle: First, the concrete test specimen is placed on the permeable plate 14. As the screw 16 is screwed in, the rubber block moves, thus clamping the concrete test specimen. Then, the metering pump 13 is started by the external controller, drawing external water into the nozzle 17 to pressurize the concrete test specimen. The perforated design of the permeable plate 14 provides support for the concrete test specimen and facilitates water flow into the water collection tank 3 for collection, making it easier for staff to clean and reducing the impact of wastewater on the test environment. After the concrete impermeability test is completed, the scale 4 can be moved by the cooperation of the slider 11 and the slide rail 10 and pushed towards the concrete test specimen. Then, the lifting plate 8 is pushed down along the outer wall of the limit rod 6 by the force of the spring 7, so that the probe 9 comes into contact with the inner wall of the permeable hole. The staff can then use the scale 4 to measure the penetration depth, providing data for the impermeability test.
