Abstract

Устройство для подводной выемки и всасывания грунта содержит всасывающую головку (1), имеющую входное отверстие (3) на свободном наружном конце и выходное отверстие (12), соединенное со всасывающим шлангом (10), расположенным на расстоянии от входного отверстия (3). Всасывающая головка (1) установлена на гидравлической управляющей руке (13) и снабжена у входного отверстия (3) механическими и гидравлическими средствами измельчения твердого материала (отложений). Гидравлические средства содержат множество струйных сопел (7), а механические средства содержат стержни (4,5). Площадь поперечного сечения входного отверстия (3) больше площади поперечного сечения выходного отверстия (12).
