METHOD OF BUILDING EARTHEN STRUCTURES BY HYDRAULIC DEPOSITION OF SOIL Russian patent published in 1997 - IPC

FIELD: hydromechanization works; building of road hydraulic fills and subgrades. SUBSTANCE: method comes to working the soil in quarry by suction tube dredger, transportation of slurry along pipeline to thickener, delivery of thickened slurry along turnable distributing pipe to zone of filling and return of water from thickener into quarry. When delivering thickened slurry into filling zone distance from thickener to discharge hole in distributing pipe is changed either by telescoping the pipe or making several discharge holes over pipe length. Slurry is additionally distributed over area by passing it through divider. Side slopes in form of bankings are formed by changing position of distributing pipe and distance from discharge hole. Zone formed by banking walls is filled with slurry. EFFECT: facilitated building of earthen structures. 3 cl, 2 dwg
