Instrumentation of a Section of AC Pipe in Expansive Soil
The City of Regina, SK, Canada, has been developed on a post-glacial lake deposit, called Regina Clay. The deposit is highly plastic, unsaturated, expansive clay that exhibits large volume changes as the soil water content changes. The water distribution system of the City of Regina has about 530 km of asbestos cement (AC) water mains. The rate of water main breakage has increased recently in old areas. A study was conducted by the National Research Council Canada, Center for Sustainable Infrastructure Research in Regina to investigate the causes of failures of the water mains. Field instrumentation was successfully installed to monitor the performance of a replacement section of a 150 mm diameter AC water main in south Regina, where failures are frequent, to learn about soil behaviour and its interaction with this type of pipe. The instrumentation included sensors to measure pipe wall strains, in situ soil water content, soil movement, soil stress and temperature. Measurements were made in the pipe trench backfill and in the native soil around the backfill. This paper presents the first year monitoring data of the test section.
