AI Technical Summary
Existing concrete permeability testing devices cannot simulate impact disturbance loads and cannot accurately evaluate the durability of concrete components under complex service environments.
A device for testing the water seepage of concrete specimens under impact disturbance was designed. The device applies downward impact force and upward pre-tightening force through two force-applying mechanisms to simulate the dynamic disturbance environment of concrete components in actual service. A double sealing structure is adopted to ensure that the water flows along a predetermined path, and a motorized linear actuator is used to achieve precise control.
It enables accurate assessment of water seepage in concrete components under dynamic loads, allowing for better prediction of their service durability and improving the accuracy and reliability of the test.
