FIELD: hydraulic engineering. SUBSTANCE: method consists in that in local area of sandy soil, where drawdown is to be effected, holes are drilled along one straight line spaced at 10-15 m and reinforced with perforated casing, layer of crushed stone is laid on hole bottom. Lowered in holes are branch pipes of pump and ground water is pumped out. To increase efficiency of the process placed on hole bottom is vibration source exciting elastic vibrations within 60-1500 Hz, local part of ground is subjected to excitation and ground water is pumped out in combination with vibration effect. EFFECT: higher efficiency. 5 cl, 1 dwg
