Description

Technical Field

[0002] Channel lining refers to a protective measure used in waterway engineering to protect the shoreline and improve its protective capacity. Concrete lining is the most widespread form of channel lining, typically using concrete materials spread on the slope surface to form a retaining wall structure, thereby improving water resistance and erosion resistance. Although concrete lining has high water conveyance efficiency, its frost resistance and adaptability to foundation deformation are poor. To improve the concrete lining's adaptability to deformation caused by temperature changes and foundation settlement, expansion joints are generally installed in the channel lining. However, the presence of expansion joints reduces the water-stopping effect. To compensate for these shortcomings, existing technologies generally install rubber waterstops under the lining. However, existing rubber waterstops have poor deformation adaptability. When the channel lining deforms due to temperature changes or foundation settlement, gaps appear between the rubber waterstop and the channel lining, reducing the water-stopping effect. Utility Model Content
