Description

Technical Field

[0001] The invention relates to the field of construction engineering, in particular to a full-automatic concrete impermeability tester. Background Art

[0002] As a widely used building material, the impermeability of concrete is one of the key factors to ensure the durability and safety of the structure. Concrete with good impermeability can effectively prevent the penetration of moisture and harmful substances, thereby slowing down structural corrosion and enhancing durability. Therefore, evaluating the impermeability of concrete is crucial for quality control and life prediction of construction projects.

[0003] Existing concrete permeability testers usually include a closed test chamber for placing concrete samples and applying pressure to the samples through a hydraulic or pneumatic system to simulate the water pressure environment under actual use conditions. These devices can measure the amount of water seepage in a concrete sample over a certain period of time by setting different pressure levels in a controlled environment, thereby deriving its permeability performance index. In this way, engineers can predict the performance changes of concrete structures under long-term stress and environmental influences.

[0004] Although existing concrete impermeability testers can provide basic impermeability performance tests, they usually have some limitations, such as low test efficiency and inability to process multiple samples at the same time, which is particularly evident in engineering projects that require a large number of sample tests. In addition, existing equipment often requires more manual operation and maintenance, which not only increases labor costs, but also increases the risk of test errors caused by human operating errors. These shortcomings limit the application efficiency and reliability of concrete impermeability performance tests. Summary of the invention

[0023] After the detection is completed, the sprocket is driven by the motor to rotate in the opposite direction, so that the mounting seat is separated from the sleeve and the pressure inside the sleeve is discharged. At this time, the infiltrated water can be collected by the box body, and the collected water can be gathered and discharged from the device under the action of the connecting pipe.

[0024] The present invention provides a fully automatic concrete impermeability tester. It has the following beneficial effects:
