Optimization of the dimensional parameters of the working body for compaction temporary sprinkler dams

The article presents the results of research work to optimize the working dimensions of the sealing working bodies of the dammer. A ski-shaped sealing sheet and a cone roller are used as working elements to seal the outer and inner parts of the temporary sprinkler dam. The sealing sheet of the sliding working body compresses, thanks to the presence of the inclined cheek SH and eliminates the restoration of compacted soil with the EC section. When the sealing sheet moves along the surface of the dam slope, it is immersed under the action of its own weight or the pressure force of the additional loader (spring) by the value h 1 , the soil layer with the thickness h 1 is pressed into the body of the dam. In this case, the nature of the impact of the compacting cheek of the face on the lump of soil depends on the value of the angle αl of its inclination to the horizon and the speed of movement. To seal the outer part of the dam, take a cone roller as a working body. To substantiate the parameters of the conical working body, conical working elements were manufactured with a change in the large diameter of the truncated cone and different sizes of sealing sheets. During operation, the roller rotates on its axis with sliding and has no torque on the shaft. To find out the effect of sliding on the value of the longitudinal movement of the compacted soil particles on the surface of the dam, the nature of the effect of the base of the conical part of the roller on them is graphically considered.
