2results about How to "Comprehensive detection effect" patented technology

This utility model discloses a high-performance concrete impermeability testing device, including a testing box and a test block. The test block is slidably connected inside the testing box, and a testing component is movably connected above the test block inside the testing box. The advantages are: by installing a pressure plate inside the testing cylinder and the pressure cylinder, and configuring an electric push rod for driving the pressure plate to adjust its displacement, this utility model achieves flexible and precise adjustment of the water pressure inside the testing cylinder and the pressure cylinder. Therefore, the testing device can perform more accurate testing on the concrete test block. Furthermore, it can control the pressure plate to increase the water pressure at an appropriate time and decrease it after an appropriate time, thus achieving a more comprehensive testing effect on the concrete test block. Alternatively, it can control the pressure plate to continuously increase the water pressure at a certain speed and gradually decrease it after reaching a set value, thereby achieving a linear testing effect.
