The requirements for electromechanical repair and maintenance of water conservancy projects are: job quota standards for water conservancy project management units and quota standards for water conservancy project repair and maintenance.

The damage caused by various types of hydraulic structures varies. Cracks, water seepage and surface damage often occur in earth, stone and concrete buildings. In addition, geotechnical buildings may also suffer from slope instability, slope protection failure, and downstream seepage damage problems such as piping and flowing soil.

River banks, reservoir banks and hillsides related to buildings may collapse and slide, thus affecting the safety and use of buildings; water conveyance, water discharge and energy dissipation buildings may suffer from erosion and cavitation erosion and abrasive damage.

Water conservancy project maintenance scope:

The surface of earth, stone and concrete buildings must be kept intact, blasting near the project is strictly prohibited, and various external sabotage activities and adverse factors must be prevented from damaging the project. damage, regular inspections should be conducted to understand the external conditions of the project, and monitoring methods should be used to understand the internal safety conditions of the project; the drainage system of the dam and its downstream decompression drainage facilities should be regularly dredged, cleaned, and kept smooth.

If there is any minor damage to the energy dissipation facilities downstream of the water discharge building, they must be repaired immediately to avoid aggravating the damage after water discharge during the flood season and freezing in winter; frequent desilting and sand discharge in front of the gates and waste rails; Steel structures should be rust-protected regularly; lubricants should be regularly added to hoisting and closing equipment to facilitate opening and closing; artificial destruction and obstacles are strictly prohibited on rivers and embankments, and the integrity of the embankments must be maintained.
