Technical criteria for choosing an excavator for pit development
Incoming article date: 05.01.2021Information modeling of construction processes should be attributed to the actual problems of development of technology and organization of construction. An important part of the information model is the geometric description of the technological sites (excavator faces). When designing technological sites (faces) of excavators, it is recommended to use the maximum digging radius on the ground surface as a criterion, taking into account the conditions of work (types of soil). To calculate the minimum value of the digging radius, a mathematical expression is proposed, which contains a complex indicator describing the physical and mechanical characteristics of the soil (tga). The results obtained allow us to cut off earthmoving machines at the decision-making stage by the size of the maximum digging radius on the earth's surface. These results describe the first step in the information modeling of the process of excavation by an excavator.
