Title of the articleMethod of selection of the dredger for dredging sand and gravel from the bottom of the River Kama
Abstract.In the context of the raging worldwide economic crisis, taking into account the need to ensure continued economic development, reduce pollution, economical use of all resources and technology, the subject of a rational choice of construction machinery and equipment is becoming more important. The relevance of the article is to develop procedures for the selection of the dredger for dredging sand and gravel from the bottom of the Kama River, providing a reduction of performance time, reduction of material costs for the preparation and execution of works, minimizing potential accidents dredge, as well as reducing the negative impact on the ecology of the reservoir. In order to solve this problem, the domestic and foreign dredgers Nizhegorodets-1, Nizhegorodets-2, ZRS-M, Beyer B550, the formulas for calculation of these parameters were analyzed, presented the design scheme and operation of the dredge was conducted patent research, based on which have been proposed various methods for improving productivity, revealed their advantages and disadvantages. The article is devoted to a rational choice of a dredger on the basis of a systematic approach, which consists in selecting the dredger performance by calculating the main parameters. When comparing the domestic and foreign dredgers was identified a significant gap in a number of characteristics, such as performance and maximum depth of excavation. Therefore, on the basis of the modern Russian development recommendations for the introduction of innovative technology resources and increase the efficiency of the dredger in order to increase the volume of soil excavated from the bottom of dredger Kama rivers and other water bodies of the city of Perm and the Perm region.
Keywords.dredger, capacity, sludge, slurry pipeline, pressure, pump, cultivator, slurry, alluvium, soil.
