The invention relates to a method for producing a contiguous ice body in a ground region, wherein first cooling lances are inserted into the ground region in which the contiguous ice body is to be produced in the presence of a flow of a fluid flow medium flowing through the ground region, in particular in the form of groundwater, wherein a first coolant is introduced into the first cooling lances, and wherein furthermore at least one second cooling lance is introduced into the ground region on a side of the first cooling lances facing the flow and a second coolant, which has a temperature that is lower than the temperature of the first coolant, is introduced into the at least one second cooling lance in order to support the formation of a contiguous ice body that surrounds all of the cooling lances.
A method for producing a contiguous ice body in a ground region, comprising inserting first cooling lances into the ground region, in which the contiguous ice body should be produced in the presence of a flow of a fluidic flow medium flowing through the ground region, introducing a first refrigerant into the first cooling lances, and furthermore inserting at least one second cooling lance into the ground region on a side of the first cooling lances facing the flow and introducing a second refrigerant, which has a temperature that is lower than the temperature of the first refrigerant, into the at least one second cooling lance in order to promote the formation of a contiguous ice body enclosing all cooling lances.
