Abstract
1. Способ глубинного отбора донного грунта, включающий образование между грунтом и накрытой на него гибкой оболочкой, поджимаемой по периметру к грунту равномерно распределенной нагрузкой, охлаждаемого объема, в котором замораживание грунта происходит сначала по периметру оболочки, затем после сокращения охлаждаемого объема замораживание продолжается по всей поверхности оболочки до заданного значения промерзания грунта.2. Устройство, содержащее теплоизоляционную, гибкую оболочку, имеющую форму усеченного конуса, и расположенными с внешней стороны по периферии балластными грузами, а внутри оболочки закреплены периферийный и центровой испарители, имеющие сильфонную форму, причем объем оболочки через клапан связан с баллоном, содержащим воздух низкого давления.3. Устройство по п. 2, отличающееся тем, что вместо балластных грузов на гибкой оболочке закреплены грузоподъемные электромагниты.1. A method of deep sampling of bottom soil, including the formation between the soil and a flexible shell covered by it, pressed along the perimeter of the soil with an evenly distributed load, of a cooled volume in which the soil is frozen first around the perimeter of the shell, then after the cooling volume is reduced, freezing continues throughout the surface of the shell to a specified value of freezing. 2. A device containing a heat-insulating, flexible shell having the shape of a truncated cone and ballast weights located on the periphery on the periphery, and peripheral and center evaporators having a bellows shape are fixed inside the shell, the shell volume through a valve connected to a cylinder containing low pressure air. 3. The device according to claim 2, characterized in that instead of ballast weights, lifting electromagnets are fixed on a flexible shell.
