The Maintenance and Inspection of Inflatable Rubber Dams: The lifespan of the rubber dam bags is related to factors such as climate, usage regulations, load-bearing conditions, and the production quality, thickness, etc. of the dam bags.

Prior to inflating the berm bags, the sediment fine sand around the bottom area of the downstream berm bag collapse zone and on the berm bags must be thoroughly cleared, and floating debris that could pierce the berm bags should be swept and retrieved.

2) During overflow, the dam bag may experience impacts or vibrations. In practice, methods such as increasing or decreasing the dam height are often used to prevent the bag from producing impacts or vibrations during overflow. It is prohibited to operate the inflatable rubber dam at excessive pressure, meaning that filling (with water or air) must not exceed the designed pressure.

3) During hot weather, the dam height can be moderately reduced to produce short-term overflow behind the dam, or water can be sprinkled on the dam surface to cool it down, in order to slow down the aging rate and erosion level of the dam bags.

4) Inspection of the exterior mineral wool board focuses on checking for any exposed areas, loose fitting, or water leakage. In case of any anomalies, promptly implement countermeasures such as tightening, securing, sealing, or replacing as needed.

5) The concrete central pier or side pier in contact with the inflatable rubber dam head is timely coated with epoxy resin mortar, maintaining a smooth surface, reducing the vibration and swinging friction of the dam bag, and extending the service life of the dam bag.

6) In cases of punctures, scratches, and渗水 issues with inflatable rubber dams, emergency repair measures can include using wood wrapped with cloth to plug the leaks, patching with barge cloth by making holes and tightening bolts, and securing belt buckles. For large-scale渗水, cold bonding repairs to the collapsed dam section or complete replacement of the dam section can be employed.

That concludes the methods for the maintenance and repair of inflatable rubber dams. If you have any further questions, please feel free to contact us.
