Abstract: After having been used for 30years,the emergency gate, along with working gate and slots were badly damaged by sand erosion and leaked severely. The rehabilitation is very difficult. We have come up with a series of new technology to solve those problems, it includes changing filling water valve, repairing gate body, zincing for anti-erosion work under high density dust and carrying out anti-seepage and blocking leakage under different conditions and surrounding. It proved to be a good method and got good result.
