摘要：The present invention relates to an apparatus or device for storing elongatedflexible elements, such as drilling pipe, in a coiled form. This apparatus includes an innercylindrical framework supported about a vertical axis, an outer cylindrical frameworkconcentrically separated from the inner framework and connected thereto by an annularbase plate closing the bottom of the apparatus. The space between the inner and outerframeworks is open at the top to receive the elongated elements, and the annular baseplate is formed of a plurality of annular sector elements connected together in such amanner as to allow a vertical displacement of respective adjacent elements with respectto one another. Various means for connecting adjacent elements are provided. Moreover,various driving and supporting members are provided for rotating the apparatus aboutthe vertical axis.
