Abstract: Height-adjustable fixtures for buried tubulars and methods of adjusting the height- adjustable fixtures. The height-adjustable fixtures include a frame and a plurality of slot nuts. The frame has an upper frame surface, a lower frame surface, a flange that defines a plurality of slots, and a central opening that extends between the upper frame surface and the lower frame surface. The central opening is sized to provide access to a buried tubular conduit of the buried tubular. Each slot nut is shaped to be received within a corresponding slot. In some examples, each slot nut defines a lower nut surface, an upper nut surface, and a neck region positioned between the lower nut surface and the upper nut surface. In some examples, when each slot nut is received within the corresponding slot, the lower nut surface is recessed within the corresponding slot.

Abstract: Adjustable fixtures for buried tubulars, forming tools for defining a hole in the adjustable fixtures, and/or methods of manufacturing the adjustable fixtures. The adjustable fixtures include a fixture body and a plurality of spaced-apart holes extending between an upper surface of the fixture body and a lower surface of the fixture body. The adjustable fixtures also include a plurality of jack-screw-accepting threaded regions that at least partially defines the plurality of spaced-apart holes. The forming tools include a forming tool engagement structure, a threaded tool end region, and a hole-defining body. The methods include positioning a plurality of jack- screw-accepting threaded regions and a plurality of forming tools within a mold, filling a fixture-defining cavity of the mold with a composite material, curing the composite material, disengaging the plurality of forming tools from the plurality of jack-screw-accepting threaded regions, and removing the fixture body from the mold.
