Abstract:
A method for maintaining a stable soil by surrounding a chilled gas pipe with a material that has an antifreeze component that prevents the soil from freezing. By keeping the soil from freezing, it remains stable at all times. The method calls for excavating a trench, lining it with a geotextile membrane that keeps water from infiltrating into the trench, and then surrounding it with a bed of limestone (calcium carbonate) that is mixed with calcium magnesium acetate (CMA), which acts as an anti-freeze agent. The limestone-CMA mixture surrounds the pipe. The trench is covered by another geotextile membrane to completely seal it. In this way, the pipeline is surrounded by a material that is not subject to freezing. As such, it provides a stable bed for the pipeline to prevent frost heaving.
