Abstract
In one aspect, the present invention provides a stabiliser for stabilising earth, rock or other structures, the stabiliser having a hollow elongate body portion including an opening extending substantially the entire length of the body portion and a closure member aligned to substantially cover the opening of the body portion, the closure member being configured to extend substantially parallel to an inner wall of the body portion in the vicinity of the opening. The present invention also provides a stabiliser assembly including: a stabiliser for stabilising earth, rock or other structures, the stabiliser having an elongate body portion including an opening extending substantially the entire length of the body portion; a closure member aligned to substantially cover the opening of the body portion; and a cartridge containing filler material in a bag of permeable material, the bag being shaped to substantially conform to the internal dimensions of the stabiliser body; wherein the closure member substantially covering the opening of the body portion significantly reduces the likelihood of a cartridge becoming ensnared upon the internal wall of a hole during insertion of the stabiliser assembly into a hole.

4. A stabiliser according to any one of the preceding claims wherein the closure member is a sleeve segment with one of the longitudinal edges of the sleeve segment being affixed to the internal wall of the stabiliser body and the other longitudinal edge remaining free to move relative to the stabiliser body thus allowing the opening to close upon application of a sufficient compressive force whilst retaining the sleeve segment in a position relative to the opening to substantially cover the opening.
5. A stabiliser according to any one of the preceding claims wherein the closure member is shaped to substantially conform with the shape of the inner wall of the stabiliser body in the vicinity of the opening.
6. A method of installing a grouted friction stabiliser, the method including the steps of:
a. drilling a hole in the region to be stabilised, the hole having a smaller diameter than the diameter of the stabiliser to be installed, b. placing at least one cartridge containing a filler substance internal of the stabiliser; and c. inserting the stabiliser into the hole.
a. drilling a hole in the region to be stabilised, the hole having a smaller diameter than the diameter of the stabiliser to be installed, b. placing at least one cartridge containing a filler substance internal of the stabiliser; and c. inserting the stabiliser into the hole.
7. A method according to claim 6 wherein at least one cartridge is exposed to activating fluid to activate setting of the filler material prior to placement in the stabiliser.
8. A method according to claim 6 wherein the stabiliser is immersed in activating fluid subsequent to placement of a cartridge into the stabiliser and prior to insertion of stabiliser into a hole.
9. A method according to any one of claims 6, 7 or 8 wherein the stabiliser is a stabiliser according to any one of claims 1 to 5.
10. A method according to any one of claims 6 to 9 wherein the filler material is grout and the activating fluid is water.
11. A cartridge for use in a stabiliser, the cartridge containing filler material in a bag including at least a portion of fluid permeable material said bag shaped to substantially conform to the internal dimensions of a stabiliser body.
12. A cartridge according to claim 11 wherein the filler material is grout which is is activated by exposure to water and removal therefrom commences a setting process.
13. A cartridge according to either claim 11 or 12 including a closure member attached thereto.
14. A cartridge according to claim 13 wherein the closure member is a sleeve segment adhered to the external surface of the cartridge.
15. A cartridge according to claim 14 wherein the sleeve segment is shaped to conform with the shape of the internal wall of a stabiliser body in the vicinity of an opening in the wall of the stabiliser body.
16. A cartridge according to either claim 14 or 15 wherein the closure member includes a locating protuberance for aligning the closure member with an opening in the wall of a stabiliser body.
17. A cartridge according to either claim 11 or 12 wherein the cartridge is contained within a relatively rigid structure said structure including apertures to enable the ingress of activating fluid.
18. A filler delivery system adapted to install filler into a stabiliser, the delivery system including:
a containing device adapted to contain a predetermined quantity of filler, which when activated, allows the filler to harden to a relatively incompressible state, and wherein the containing device has a profile which is substantially elongate relative to its cross-sectional area, the containing device being of a size which facilitates insertion of the device into a stabiliser.
