Results of monitoring temperature fields in the basement of the Triumph Stadium in Yakutsk
Annotation
Efficiency control of the so called seasonally operating cooling devices installed to strengthen the foundation of the Triumph Stadium (Yakutsk) is described. These devices are Y-type steel pipes, with the upper part having radiators and the underground part filled with coolant. At subzero environment temperatures the coolant gas circulates in the device, thus leading to ground temperature decrease. The device operates this way during the cold season providing ground freezing in thawed areas. To conduct the monitoring we have chosen the data loggers produced by Dallas Semiconductors. On their basis, in collaboration with ElIn Company (Moscow), we developed thermistor chains which were placed into the wells in the vicinity of the seasonally operating cooling devices. Possessing nonvolatile memory, they continuously recorded the temperature. As a result, the data of ground temperatures at various depths were obtained for a three-year period. The analysis of changes in ground temperature clearly demonstrates the effectiveness of the seasonally operating cooling devices.
