Choice and justification oF the complexes of machines for cleaning drainage channels based on reclamation requirements
Presents the results of studies of drainage canals, the number and amounts of sediments in the channels. Indicated the need for cleaning and maintenance of channels in a healthy state. Lists the operations to clear channels, on the basis of which can be formed by a different set of machines. At the outset, distinction must be made between irrigation and drainage zone. Differences in terms of zones of mechanization is big enough. This refers to the nomenclature of the maintenance operations, constructive forms of channels, the ratio of their geometrical dimensions, specific volume, types of cleaning of vegetation, and to the additional restrictions associated with the width of the dams, approaches to channels availability of anchorages and coatings, etc., it is obvious that it is necessary to have two sets of machines for drainage and irrigation zone. Of course, that individual machines or working bodies of each of these systems can be quite identical, but in general you should expect a completely self-contained complexes. Currently on reclamation systems in the Russian Federation there is a different condition: from efficient drainage systems with frequent flushes of the bottom and slopes of channels to those channels on which cleaning is not carried out at all.
