Analysis of drainage canal defects and review of canal cleaner designs

The drainage system elements, namely, the canals, lose their initial design characteristics over time. In general, canals with unstable profiles are often in reclamation construction. problems of are, primarily, related to physical and mechanical properties soils, formation internal mechanical, as well chemical biological processes occurring by action natural conditions. Maximum stability is characteristic for formed cohesive organic various kinds peat thickness considerably exceeding depth canal. With insignificant above mineral canal slopes will be rather insignificant. Wood peats most stable among soils. laid sapropelic soils characterized flow have low stability. That why, required wet can achieved removing excess moisture. made clays loams large relatively high
