СПОСОБ И УСТРОЙСТВО ДЛЯ ЗАДЕЛКИ ТРЕЩИН В ГИДРОТЕХНИЧЕСКИХ СООРУЖЕНИЯХ

摘要

FIELD: hydraulic building, particularly to seal cracks in underwater part of hydraulic structure. ^ SUBSTANCE: method for crack sealing by introduction of grout in cracks under the action of ultrasound oscillations involves fixedly securing bath filled with water and provided with nipple system to dam body so that closed cavity is created, wherein one cavity wall is defined by dam body; opening two nipples; supplying air via the first nipple to displace water from bath via the second nipple; closing the second nipple; terminating air supply; opening another nipple to feed ground via the nipple along with air discharge from air delivery nipple; closing air delivery nipple after bath filling with grout and continuing grout supply to create necessary grout pressure in bath; switching-on ultrasound oscillator as necessary grout pressure is achieved to generate ultrasound oscillations is the grout and to provide deep grout penetration in small cracks; switching-off ultrasound oscillator after crack sealing and reducing grout pressure is in bath; feeding air to displace grout in initial vessel; closing grout delivery nipple; reducing air pressure and opening water delivery nipple so that water fills the bath. As air is discharged and bath is filled air delivery nipple is closed, bath is separated and connected to next dam body area. ^ EFFECT: increased quality of crack sealing. ^ 1 dwg
