Definitions

  • the present invention relates to ground surface access assemblies.
  • a ground surface access assembly is known from prior art EP 323 944 A1 for instance.
  • ground surface access assemblies comprise a frame defining an opening and one or more covers which locate onto the frame in or above the opening.
  • the or one or each cover is openable or removable to permit access to underground services via the opening.
  • the frame is laid on a bed of bedding material such as mortar on top of a chamber structure formed of concrete or brick.
  • Surround material (which could comprise underlying foundation material, bedding material, haunching material, sub base material, road base material and surfacing material) is then installed up to ground surface level, substantially to the top of the frame, so that the sides of the frame are fully covered.
  • the terms inner, outer, inwardly and outwardly, when used in relation to the frame, are used with respect to the opening, which is inward of the frame, and the terms upward and downward are used in relation to the in use orientation of a ground surface access assembly, in which downward means down into the ground.
  • cover has been used to mean solid and/or gridded covers (gratings).
  • the invention is a ground surface access assembly with the features of claim 1, The additional features of claims 2-14 describe further embodiments of said assembly.
  • Figs. 1 and 2 show a prior art ground surface access assembly 10.
  • the assembly 10 includes a frame 12 defining an opening 14.
  • the frame 12 includes a mounting 16 for a cover 18, which is arranged so that, in use, the cover 18 locates in the opening 14.
  • the frame 12 includes four side members 94.
  • Each side member 94 includes an upstanding side wall 40.
  • Each side wall 40 includes an outer side wall surface 38 and an inner side wall surface 42.
  • Each side member 94 includes a base wall 44.
  • Each base wall 44 includes a flange part 90, which projects outwardly from a lowermost part of one or more of the side walls 40.
  • the ground surface access assembly 10 includes a pair of covers 18.
  • the mounting 16 includes mounting projections 17, which project inwardly from the side walls 40, for mounting the cover 18.
  • the mounting projections 17 are spaced upwardly from the base walls 44.
  • each cover 18 is mounted so that it contacts the frame 12 at three points, to provide non-rock mounting.
  • the frame 12 and the covers 18 are formed by casting of cast iron, which could be ductile iron.
  • Fig. 2 shows the prior art ground surface access assembly 10 in an installed condition.
  • the frame 12 is laid on a layer 88 of bedding material 78 (such as mortar) on top of an upper part 22 of a chamber structure 80, which defines a passage 24 which communicates with the opening 14.
  • the chamber structure 80 could be formed of concrete or brick.
  • the upper chamber part 22 includes outer side wall surfaces 36.
  • Surround material 82 (which could comprise underlying foundation material, bedding material, haunching material, sub base material, road base material and surfacing material) is then installed up to ground surface level 84, substantially to the top of the frame 12.
  • the outwardly extending base walls 44 extend laterally outwardly beyond the outer side wall surfaces 36 of the upper chamber part 22. This provides the advantage that the span distances between the mounting projections 34 for the covers 18 are minimised, which assists in reducing product weight.
  • this arrangement causes a number of disadvantages.
  • braking forces apply horizontal lateral loads (arrow F H , Fig. 2 ) to the covers 18 and the frame 12, resulting in horizontally extending shear stress planes being formed in the bedding layer 88, between the bedding layer 88 and the frame 12 and between the bedding layer 88 and the upper chamber part 22.
  • the stress planes can cause failure planes resulting in lateral movement of the frame 12 relative to the upper chamber part 22 (arrow L).
  • loading on the surround material 82 can be transmitted through the surround material 82 to dislodge or distort the chamber upper part 22 of the chamber structure (arrows F R ).
  • Figs. 3 to 5 show a first embodiment of a ground surface access assembly 110 according to the invention, many features of which are similar to those already described in relation to the prior art arrangement of Figs 1 and 2 . Therefore, for the sake of brevity, the following embodiment will only be described in so far as it differs from the arrangement already described.
