Аннотация (краткое описание)
In Kazakhstan, more than 70 engineering anti-sedimentation protective structures are operated, most of which were put into operation in the period 1974–1985. During the same time, more than 30 mudflows were registered in the basins of mudflows, many of which were accompanied by the removal of a large amount of solid material to the protective structures, and the issues of cleaning mudflows by excavators are annual planned work of the operational divisions of Kazselezashchita. The main type of engineering protection is the construction of capital dams with village storages capable of accommodating from 100 thousand m3 to 15 million m3 of mudflow. The types of structures are different: dams of settling tanks and sections of stabilized channels within cities and settlements, for safe passage of post-mudflows and nanowater flows. In connection with their long-term operation, the issue of frequency, methods and means of mechanization of cleaning of silos, settling tanks, selesbass paths, and the amount of annual costs for work becomes more and more urgent. However, the issues of operating dams in the conditions of annual nanowater floods, the development of modern technologies and means of mechanization of cleaning silos from coarse clastic soils are very relevant. The value of the work consists in the development of the design and manufacture of a prototype, methods for calculating and selecting the parameters of the bucket of an excavator with a hydraulically controlled jaw for excavation during the development of large-fragment inclusions of mudslides.DOI

d on the results of the work, the following conclusions were made: - It has been established that the most difficult to develop in the sections of dams, selectors are coarse clastic soils, which require the creation of special RC in order to increase the efficiency of traditional earthmoving machines, widely used in emergency situations. The total content of fractions with a diameter of 200 to 1000 mm of mudflows in sediments of river basins on the northern slope of the Zailiysky Alatau is 23,7 % (р = 0,217); – An algorithm and method for determining the positions of the links of the mechanism for opening the guide-controlled jaw of the excavator bucket have been developed, which make it possible to determine the coordinates of points of any link using formed matrices, vectors, formulas for transferring and rotating coordinate axes relative to stationary coordinate systems; – An algorithm and method for determining the positions of the links of the mechanism for opening the guide-controlled jaw of the excavator bucket have been developed, which make it possible to determine the coordinates of points of any link using formed matrices, vectors, formulas for transferring and rotating coordinate axes relative to stationary coordinate systems.Impact Factor
