The invention disclosed is an adjustable support adapted to support an access hatch frame for access to a sub-surface chamber or the like. The support has a lower frame member that at least in part defines a first aperture, the first aperture having or defining a first plane, the lower frame member having at least one upper interface surface. A similar upper frame is present that defines a second aperture, a second plane, and a lower interface surface. Upper frame member also has number of height adjustable mount points. The upper and lower interface surfaces define an interface plane. Rotation of the upper frame member, relative to said lower frame member on the interface plane, adjusts the relative angle of the two.

1. An adjustable support adapted to support an access hatch frame for access to a sub-surface chamber, comprising: a lower frame member that at least in part defines a first aperture, said first aperture having or defining a first plane, said lower frame member having at least one upper interface surface;an upper frame member that at least in part defines a second aperture, said second aperture also having or defining a second plane, said upper frame member also having at least one lower interface surface, and a plurality of height adjustable mount points; andwherein said at least one upper interface surface and said at least one lower interface surface define a planar interface, located on or parallel to an interface plane, said interface plane not being parallel to either of said first or second planes, wherein said lower interface surface and said upper interface surface are bevelled to aid engagement thereof, such that rotation of said upper frame member relative to said lower frame member about or on said planar interface varies the relative angle of said first plane to said second plane, said relative rotation and said height adjustable mount points allowing adjustment of said relative angle and height, relative to said upper frame member and said lower frame member, of a third member adapted to be mounted from said upper frame member via said plurality of height adjustable mount points. 2. A frame as claimed in claim 1 wherein said third member is an access hatch frame that at least in part defines a third aperture. 3. A frame as claimed in claim 2 wherein said access hatch frame is adapted to receive a hatch cover that at least part covers said third aperture. 4. A frame as claimed in claim 2 wherein said upper frame member, lower frame member, and access hatch frame via said first aperture, second aperture and third aperture define an access passage to said sub-surface chamber or the like when mounted thereto and said hatch cover at least in part closes off said access passage. 5. A frame as claimed in claim 2 wherein said sub-surface chamber is substantially sealed from access by said adjustable support, access hatch frame and said hatch cover. 6. A frame as claimed in claim 1 wherein said plurality of height adjustable mount points are adjustable members that extend from said upper frame member to said access hatch frame. 7. A frame as claimed in claim 6 wherein said adjustable members are infinitely adjustable over the height they mount said access hatch frame from said upper frame member. 8. A frame as claimed in claim 6 wherein said adjustable members are step-wise adjustable over the height they mount said access hatch frame from said upper frame member. 9. A frame as claimed in claim 6 wherein said adjustable members are threaded adjustable members. 10. A frame as claimed in claim 6 wherein said adjustable members are stepped adjustable members. 11. A frame as claimed in claim 1, wherein the lower frame element and upper frame element are concrete elements. 12. A method of installing an adjustable support for an access hatch frame for a sub-surface chamber, comprising the steps of: i. Locating a lower frame member onto a sub-surface chamber, said lower frame member at least in part defining a first aperture, said first aperture having or defining a first plane, said lower frame member having at least one upper interface surface,ii. Locating an upper frame member via at least one lower interface surface thereof onto said at least one upper interface surface, said upper frame member at least in part defining a second aperture, said second aperture also having or defining a second plane, said at least one upper interface surface and said at least one lower interface surface defining a planar interface, located on or parallel to an interface plane, said interface plane not being parallel to either of said first or second planes, wherein said lower interface surface and said upper interface surface are bevelled to aid engagement thereof,iii. Rotating said upper frame member relative to said lower frame member on said interface plane as necessary to adjust the relative angle of said upper frame member to said lower frame member,iv. Marking the relative positions of said upper frame member to said lower frame member via an indicia or indices on one of both of said upper frame member and said lower frame member,v. Mounting a third member off said upper frame member via a plurality of height adjustable mounts between said third member and said upper frame member to thereby provide said third member with adjustable relative angle and height from said sub-surface chamber to match a surface angle and height below which said sub-surface chamber is, or is to be, located. 13. A method as claimed in claim 12, further comprising: removing said upper frame member, lower frame member, and third member,preparing said sub-surface chamber or surrounding ground, andrelocating in situ on said sub-surface chamber of said upper frame member, lower frame member, and third member. 14. A method as claimed in claim 12 wherein a locking compound is located between said upper frame member and said lower frame member. 15. A method as claimed in claim 12 wherein said third member is an access hatch frame. 16. A method as claimed in claim 12 wherein fill is located about said upper frame member, lower frame member and said third member to produce said surface below which said sub-surface chamber is located. 17. A kit of parts to provide an adjustable support for an access hatch frame for a sub-surface chamber, comprising: an adjustable support comprising: i. a lower frame member that at least in part defines a first aperture, said first aperture having or defining a first plane, said lower frame member having at least one upper interface surface;ii. an upper frame member that at least in part defines a second aperture, said second aperture also having or defining a second plane, said upper frame member also having at least one lower interface surface, and a plurality of height adjustable mount points; andiii. wherein said at least one upper interface surface and said at least one lower interface surface define a planar interface, located on or parallel to an interface plane, said interface plane not being parallel to either of said first or second planes, wherein said lower interface surface and said upper interface surface are bevelled to aid engagement thereof, such that rotation of said upper frame member relative to said lower frame member about or on said planar interface varies the relative angle of said first plane to said second plane, said relative rotation and said height adjustable mount points allowing adjustment of said relative angle and height, relative to said upper frame member and said second frame member, of a third member adapted to be mounted from said upper frame member via said plurality of height adjustable mount points. 18. A kit as claimed in claim 17 wherein there is included an access hatch frame as said third member. 19. A kit as claimed in claim 17 wherein there is included a hatch cover to at least in part close said access hatch frame. 20. A kit as claimed in claim 17 including a locking material to lock said upper frame member to said lower frame member.
