Comparative Analysis of Surface Plants of the Ground Sealing Composition in the Implementation of Construction Works

Abstract

Processes of layer-by-layer consolidation of soil at construction of the bulk engineering constructions built by method of continuous consolidation are considered. Ways of realization of these processes on the basis of two technological schemes - elliptic and shuttle are shown. The assessment of key parameters is made during the operation of units on the classical elliptic scheme of continuous consolidation of soil and on the elliptic scheme with use of a ring method of a turn of the unit when in the course of construction of a road bed automobile and the railroads the movement of the condensing unit is made from roadsides to an axis. It is shown that working platform* more effective andleast critical to topographical and geometrical parameters, the shuttle scheme of consolidation at which the condensing cars make the back and forth motions accompanied with lateral shift on an adjacent working strip after achievement of the demanded density on the previous strip is. The analsis of the major factors proving application of this or that technological scheme of soil consolidation is made. Operating conditions of units depending on type of the used condensing unit and the accepted production technology of works on elliptic and shuttle schemes which realization allows to reach the greatest production effect are studied
