| Abstract: | The membrane valve is designed for lined canal lining by plastic membrane and concrete plate which is a drainage inverted valve. The valve has many advantages of sensitive action, large drainage flow, good invert perfor- mance, simple structure, cheap cost, easy construction, testing and repairing which are proved by the modelling test and practical operation in a canal section of the Huang-cai resevoir. The membrane valve is effective for release the canal bank soil water pressure and maintaining the lining stable and safety. |
