Abstract
The modernization of machines for compaction of soil on a modular basis has the following advantages: some of their structural elements (working equipment and working elements) can be performed as unified modular units, from which, depending on the technological requirements, it is possible to assemble the required configuration of the sealing machine; the initial state of the machine does not deteriorate, to which it is easy to return; the nomenclature of structural elements and machines in general decreases, as the machine can be completed with variable modules, which leads to an improvement in their quality. When consolidating the soil massive use static, dynamic and combined action on the soil in the form of rollers, vibro-and ramboards. Machines of the boottype are classified into light, medium and heavy, which determines the order of its application. It is obvious that the reduction of technology for the process of soil compaction is possible due to the creation of machines that can change the intensity of the impact on the soil in a wide range.

In modern conditions of ground works during the construction of soil embankments, in particular railway tracks, at the final stage, the issue of effective compaction of soil is relevant, since the stability of the soil structure depends to a large extent on the stability of the parameters of soil moisture and settlement load
Further intensification of soil consolidation is possible with the use of trenches and vibration tracks of shock type
Summary
In modern conditions of ground works during the construction of soil embankments, in particular railway tracks, at the final stage, the issue of effective compaction of soil is relevant, since the stability of the soil structure depends to a large extent on the stability of the parameters of soil moisture and settlement load. Known soil compacting machines (SCM) rollers, vibration plates and ramps traditionally comprise freshly ground soils in successive passages with the basic condition not exceeding the surface pressure of the working element (WE) on the soil of the boundary of soil plasticity. The order of the SCM of the boot type involves, at the first stage, the consolidation of the soil with smooth, small and medium type, with subsequent use of their vibration systems (VS), followed by cam rollers with subsequent use of the aircraft. Goal - the purpose of the work is to develop the principal variants of technical solutions of the SCM WE for accelerated blocked consolidation of soil
