Abstract
This paper considers one stage of development of a new power plant for thawing frozen soil during emergency repairs. It includes experimental study of temperature conditions for freezing and artificial thawing of various types of soils in field and laboratory conditions. The main results of laboratory research are presented. The operation process of an industrial prototype of power plant is modelled on a test bench using analogues of radiation-convective heat generators. The obtained calculated and experimental characteristics of artificial thawing of frozen soil by a surface radiation-convective method will allow one to calculate the thermal power of a power plant, and to carry out its design and thermal calculation.
Highlights
The search for new technological solutions and soil preparation systems during repair, construction and emergency operations is an important task in our country due to its harsh climatic conditions
The increased mechanical strength of frozen soils prevents their excavation by conventional technical means, which necessitates the preliminary preparation of such soils
The use of special means of soil loosening or cutting does not enable to use the mixture without a sufficient amount of thawed soil for construction of embankments, backfilling of trenches and sinuses of foundation pits due to the impossibility of high-quality compaction, since it leads to soil subsidence after thawing
Summary
The search for new technological solutions and soil preparation systems during repair, construction and emergency operations is an important task in our country due to its harsh climatic conditions. The recovery time of site directly depends on the speed of opening the damaged pipeline by the repair team Another important aspect of the problem raised above is soil preparation before construction - a task for builders conducting work in winter. The use of special means of soil loosening or cutting does not enable to use the mixture without a sufficient amount of thawed soil for construction of embankments, backfilling of trenches and sinuses of foundation pits due to the impossibility of high-quality compaction, since it leads to soil subsidence after thawing In such conditions, the use of alternative methods of soil preparation during repair, construction and emergency works expands the technical capabilities of the organization and allows ensuring the work efficiency.
