Abstract

The present invention discloses a system and method for testing the waterproof performance of a deformation joint waterproof structure. The system comprises a main structure having a hollow cavity disposed therein, the deformation joint waterproof structure and a water inlet and outlet disposed thereon; a pressure rack unit disposed outside the main structure and configured to apply axial pressure to the main structure; a pressure control unit comprising a pressure pump that injects water into the hollow cavity through the water inlet and outlet; and a processing unit comprising electrodes disposed on the main structure and a data processing device connected to the electrodes. The present invention can test the effect of axial force on the waterproof performance of the main structure, reducing test complexity and improving test accuracy.
