Abstract

Modern construction of facilities of various types is accompanied by huge volumes of excavation works. The construction of surface and subsurface facilities requires the solution of a number of complex geotechnical problems, including those related to the creation of a deep underground cavity and a volume of hundreds of thousands of cubic meters. For soils of different categories of complexity of reservoir management at different depths, in some cases up to 50 meters, rope grab buckets are used. The article is devoted to the possibility of preliminary determination of the weight of an excavator grab bucket for excavation in developing the environment by creating various types of facilities. To determine the weight of the bucket, the existing empirical dependencies and the modeling method are used, which allows choosing the optimal weight of the excavator grab bucket for specific soil conditions. In this case, unlike the existing methods, the analytical calculations conducted do not only use the mass function of the soil developed, but also take into account the specificity of its resistivity to digging. Analytical dependence is given to determine the weight of the grab bucket for construction and practical recommendation of its preliminary choice for specific excavation works.
