MODELING OF THE PROCESS OF CUTTING MINERAL GROUNDS BY PASSIVE WORKING DRAWNER DURING THE CONSTRUCTION OF CLOSED DRAINAGE

Objectives. The article describes an electronic model of the soil to study its rheological properties and study the process of cutting passive working bodies (knives) of mineral soils with trench-less method of building a closed drainage.Method. The essence of the method consists in cutting through the ground with the help of a passive working body of a narrow slit under a given slope and simultaneously laying a drainage (usually plastic) pipe with a filter on its bottom.Result. The trenchless method is characterized by the possibility of laying pipes at high speeds, the simplicity of the design of drainage machines and, most importantly, the possibility of building drainage in water-saturated and collapsing mineral soils. A big advantage is the possibility of using a drainage machine with a trenchless method in conditions of small slopes with a sufficient length of stacked drains.Conclusion. The study of the process of cutting mineral soils with narrow, deep knives on an electronic model makes it possible, at the design stage, to evaluate the effect of changes in various factors and parameters on the operating modes of the drainage machine; if necessary, make changes to the complex of works on the construction of drainage using the trenchless method with the help of the BDM-300 bed-draining machine, as well as to determine the composition and duration of the work operations of the trench-free bed-draining machine
