METHOD FOR REDUCING NOISE EMISSIONS ON GROUND FREEZING CONSTRUCTION SITES
First Claim
1. Method for creating a contiguous frozen mass (1) in an area of ground (100), wherein at least one first cooling lance (10) is introduced into the area of ground (100) in which the contiguous frozen mass (1) is to be created, a first fluid coolant (T) is fed into the at least first cooling lance (10) to support the formation of a contiguous frozen mass (1) which surrounds the at least first cooling lance (10), the first coolant (T) evaporates during formation of the contiguous frozen mass (1) and the evaporated coolant (T′
- ) is led out of the at least first cooling lance (10) in into a means (22, 24) for accommodating and/or dissipating the evaporated coolant (T′
), particularly an exhaust manifold (22) and/or an outlet pipe (24), characterized in thatnoise emissions generated during the creation of the contiguous frozen mass (1) are minimised by a soundproofing means (30, 31, 32, 33, 34, 35, 36, 37).

Abstract
The invention relates to a method for producing a contiguous frozen mass in an area of ground wherein at least one first cooling lance is introduced into the area of ground in which the contiguous frozen mass is to be generated, wherein a first fluid coolant is fed into the at least first cooling lance to support the formation of a contiguous frozen mass which surrounds the at least first cooling lance, the first coolant evaporates during formation of the contiguous frozen mass and the evaporated coolant is displaced out of the at least first cooling lance into a means for holding and/or dissipating the evaporated coolant. In this context, it is provided according to the invention that noise emissions generated during the creation of the contiguous frozen mass are minimised by a soundproofing means. The invention relates further to a device for performing the method according to the invention.
