Conclusions 1.New apparatus for a hydraulicking slurry line intended for dispersal hydraulicking, which makes it possible to build earth structures with beachside slopes on beds above and below the water line, have been developed and tested; it is expedient to use them for the hyraulicking of roads and dikes on swampy beds, narrow dikes in bodies of water, and dikes with a beachside dynamically wave-resistant slope in those cases when the slope calculated on the basis of wave resistance is significantly steeper than the slope created with the frontal method of hydraulicking.2.The slurry-line apparatus for the above-water hydraulicking of soil combines the technical merits of the trestle-free method with the advantages of the dispersal method.3.The installation of protons on the floating line for the dispersal hydraulicking of soil in water makes it possible to raise the slurry line spontaneously as the soil cone rises above the water line.4.Use of the new apparatus for dispersal hydraulicking makes it possible to shape beachside slopes 1.5 times steeper than with the frontal trestlefree method; this provides for an appreciable reduction (up to 30%) in the volume of the structure and lessens the ecological consequences during its construction.5.In each specific case, selection of the method used for the hydraulicking of structures should be based on design analysis of alternate schemes of the possible technology with allowance for reliability and economic requirements. |
