    摘要: Apparatus useful for providing a liquid-tight seal around an opening formed in the earth's surface includes a reusable load-supporting surface having at least two sealingly interconnected mats surrounding and spaced-away from the borehole opening. At least one flexible, planar spanner is configured to extend between the borehole wall and mats. At least one elongated spanner support is used to mechanically couple one or more spanners to the borehole wall. At least one elongated lip support is used to mechanically couple one or more spanners to the mats.
