As will be shown below, this is also confirmed by the fact that the zone of soil violations under the edge of the pile is relatively small, and therefore, the strength of structural ties that determines the subsequent thixotropic strengthening of the soil has slightly changed.
Around the experimental piles at the end of the process of thixotropic hardening of the soil was to dig the pit and a detailed description of its walls was made. Inspection showed that moraine loams in this area were very deformed and compacted. A multilayer shell formed around each pile. It was especially compacted in comparison with the surrounding soil and a vertical concentric layer was clearly observed in Pay, formed from overlying soils, pierced by piles when immersed.
The first layer directly adjacent to Swai consisted of the material of the humus horizon of podzolic soil, the second layer of grayish sandy loam, the third (external) layer of loam. Examinations also showed that the thickness of the layers along the length of the pile was a variable. So, the humus layer, which directly adjacent to the pile from the surface to a depth of 0.85 m, had a significant thickness, and below, along the length of the pile, sophisticated, and only the “raid” of black remained. The sandy gray shell had a noticeable thickness to a depth of 1.2 m from the surface, and below was also found only in the form of a grayish raid. The outer layer of brown loam was gradually thickened and reached the largest size at a depth, where the first two layers turned into thin colored raids. The total thickness of the sealing shell along the length of the pile remained approximately the same. At a depth of 0.75 m from the surface, the average thickness of the layers of the compacted membrane was 2 mm, respectively for the humus layer of black color, 5 mm for a sandy layer and 5 mm for loam.
