Abstract: Mass pier concrete maintenance has become a hot topic of many scholars and units, but the maintenance of pier body is still frequent. Taking the maintenance of pier and abutment of Xi'an to Hancheng line of new inter-city railway as an example, according to the characteristics of drought and water shortage in northwest area, the intelligent sprinkling maintenance system of water supply without tower in pier abutment is studied, which has the advantages of long radiation line, high maintenance pier and flexible operation, the realization of automatic water storage, timing maintenance, moisture retention function.

key words: Mass pier concrete maintenance; water supply without tower; sprinkling maintenance system
