METHOD OF BUILDING FOUNDATION FOR RESERVOIR

FIELD: construction engineering. SUBSTANCE: invention can be used at building of reservoirs on widths of heavily compressible grounds. Proposed includes making of ground cushion, bored cast-in-place piles united by ring grillage, carrying out hydraulic tests and eliminating tilting of reservoir. Novelty is that first of all driven piles are lowered preliminarily along ring through cushion to make wells for bored cast-in-place which are then filled with concrete, leaving top part non-filled, and then reinforcement frames and tubes-sleeves are installed which are fixed by means of grillage reinforcement members over wells, then ring grillage which units all piles is concreted, and reservoir is mounted with provision of possibility of access to wells. After hydraulic tests and elimination of reservoir tilting, concrete, is delivered through tubes-sleeves for filling up top parts of wells and putting cast-in-place piles in operation. EFFECT: prevention of settling of foundation and tilting of reservoir. 2 dwg
