Abstract
A laboratory device for simulating the cement sheath consolidation in the frozen soil strata includes the main body, the pressure system and the measuring system. The main body includes the fixing plate, the detachable plate and the base plate. The circular hole is provided in the center of the base. The central column or the heat insulating casing is mounted on the base through the circular hole. The fixing plate, the detachable plate, the base plate and the central column or the heat insulating casing form a cavity for preparing the core and the cement sheath. During use, the device is placed in a low temperature context, and then the frozen soil core with a hollow cylinder can be artificially fabricated. Further, the heat insulating casing holder is placed, and the cement is added to simulate the state of the cement sheath consolidation under the actual strata conditions.
