Abstract
A ground thawing device. The ground thawing device includes an insulated rectangular housing defining an interior volume with parallel sidewalls, end walls, and an open bottom. A pipe having a burn chamber connected to a first end and a second end adapted to connect to an external source of combustible gases is configured to be received through apertures disposed on the end walls. Perforations disposed along the length of the pipe allow for the combustible gas to be released in the interior volume of the housing. The burn chamber allows for an ignition source to be applied to the combustible gases carried therein. Once ignited, heat emanating from the pipe warms the interior volume and thaws the ground beneath, softening frozen soil to be excavated.
