TECHNICAL FIELD

[0002] The concrete permeability tester is a test device specially used for detecting the permeability of concrete. The permeability of concrete refers to the ability of concrete to resist the penetration of a pressurized medium (usually water). During the test, a certain water pressure is applied to the concrete test piece to simulate the water pressure environment that the concrete may be subjected to in actual engineering. During the test, the concrete test piece is installed in the specific test cavity of the instrument, and the instrument uses its own pressure system (usually a water pump and other components) to apply water pressure to the test piece, and can accurately control the size of the water pressure, the pressure increasing rate and other parameters.
[0003] During the experiment, the cylindrical concrete test piece is installed in the cylindrical sleeve, and the sleeve is fixed on the device. However, the elastic sealing gasket needs to be clamped between the outer surface of the test piece and the inner wall of the sleeve to seal the gap. However, the sealing gasket is generally clamped on the outer surface of the test piece. During the installation of the test piece, the sealing gasket may be displaced due to the friction between the sleeve and the test piece, resulting in a positional deviation from the expected set position. This makes it difficult to determine the installation position of the sealing gasket, which in turn affects the sealing effect of the sealing gasket at different positions of the test piece, and reduces the overall detection accuracy of the test piece.
[0004] In view of the above related technologies, the inventors believe that the sealing gasket between the concrete test piece and the sleeve has the defect that the sealing effect and position are not easy to control. Therefore, a concrete permeability tester for multiple groups of test pieces is proposed to solve the above problems. CONTENT OF THE INVENTION
