Execution of special geotechnical works - Ground freezing cen:proj:69130

Scope

Controlled ground freezing for construction and mining is used to provide ground support, groundwater control or structural underpinning during construction. Constructed prior to excavation, the frozen earth wall, for practical purposes, eliminates the need for sheeting of the earth, site dewatering, soil stabilization, or concern for movement of adjacent ground.
Freezing may be used for any size, shape or depth of excavation and the same refrigeration plant can be used from job to job despite a wide variation in these factors.
The document shall provide the design considerations, freezing methods and installation, structural design, monitoring requirements, and other construction considerations.
