Ground surface access assemblies
A ground surface access assembly 110 includes a frame 112 defining an opening 14 the frame 112 includes a mounting 16 for a cover 18, which is arranged so that, in use, the cover locates in the opening. The assembly includes an upper chamber part 122 of a chamber structure 80, wherein, in an assembled condition, the frame locates on and is supported by the upper chamber part the frame and the upper chamber part each include a mutually cooperating interlock feature 28, 30, which, in use and in the assembled condition, interlock to resist lateral relative movement between the frame and the upper chamber part; one of the interlock features includes a projection 34 and one of the features defines a recess 32 in which, in the assembled condition, the projection locates to provide the interlock; the upper chamber part interlock feature defines the recess and the frame interlock feature includes the projection; the frame includes one or more side members 194; each side member includes an upstanding frame side wall 40; each side member includes a base wall 144; the or some or each base wall comprises a flange part 92; each flange part projects inwardly from a lowermost part of one of the frame side walls; and no part of the base wall(s) or the flange part(s) projects outwardly from any of the side walls; the frame includes mounting projections 17 for mounting the cover, which project inwardly from the side wall, projecting over an in use vertically extending centreline of the base wall, and which are spaced upwardly from the base walls and/or the flange part; the frame being formed of a metallic material.
