Definitions

  • the present invention relates to a method of sinking and lining a shaft
  • a method of sinking and lining a shaft comprising the steps of excavating a shaft in the ground and lowering a first shaft liner into the shaft, then progressively extending the shaft downwardly by one or more repetitions of the following steps:
  • Figure 1 is a side view of a first shaft liner installed in accordance with an initial step of the method of the present invention
  • Figure 2 is a side view of excavation of earth beneath the first shaft liner
  • Figure 3 is a side view of a second shaft liner being lowered into the shaft
  • Figure 4 is a side view of the second shaft liner being suspended inside the first shaft liner
  • Figure 5 is a side view of a plug being installed over the opening of the shaft
  • Figure 6 is a side view of a headframe being used to lower the second shaft liner downwardly through the first shaft liner;
  • Figure 7 is a side view of the first and second shaft liners being secured together
  • Figure 8 is a side view of excavation of earth under the second shaft liner in preparation for installation of a third shaft liner
  • FIG 9 is a side view of an alternative method of connecting the first and second shaft liners.
  • a method of sinking and lining a shaft 10 includes the using telescoping shaft liners to line a shaft which is sunk in successive stages. Each further shaft liner is inserted through the existing shaft liners installed in the shaft to a position below the lowermost existing shaft liner.
  • an initial step in sinking and lining the shaft 10 in accordance with the present invention. Initially, the earth is excavated by known means to a depth equal to the length of a first shaft liner 12, plus the depth of a plug 14 to be used to seal across the shaft 10.
  • the first shaft liner 12 comprises a cylindrical steel liner.
  • the first shaft liner 12 is lowered into the shaft 10 and levelled.
  • the first shaft liner 12 is then secured in position by a lower concrete layer 16 provided around the first shaft liner 12 adjacent a lower end of the first shaft liner 12.
  • Preferably the lower concrete layer 16 covers around one quarter of the depth of the first shaft liner 12.
  • the volume around the first shaft liner 12 above the lower concrete layer 16 is then filled with sand 18 up to a point below an upper end of the first shaft liner 12.
  • An upper concrete layer 20 is then provided around the upper end of the first shaft liner 12.
  • the upper concrete layer 20 is provided with a recess 22 arranged to receive the plug 14 such that an upper surface of the plug 14 is level with the surface of the ground.
  • the plug 14 is then inserted into the recess 22 so that a headframe 24 may be moved onto the plug 14, over the shaft 10.
  • the plug 14 is provided with one or more suitable apertures to provide access to the shaft 10.
  • the tyres of the headframe 24 are then deflated and a sucker supported on the headframe 24 is lowered into the shaft 10 and used to excavate earth from beneath the first shaft liner 12.
  • the first shaft liner 12 remains in place due to the first and second concrete layers 16 and 20.
  • the second shaft liner 28 is constructed to have an outside diameter slightly less than the inside diameter of the first shaft liner 12. Preferably, the outside diameter of the second shaft liner 28 is around 20mm less than the inside diameter of the first shaft liner 12. The second shaft liner 28 is then lowered inside the first shaft liner 12 by a crane 30 until an upper end of the second shaft liner 28 is adjacent an upper end of the first shaft liner 12.
  • the second shaft liner 28 is suspended by slings provided attached to respective lugs on the upper end of the first shaft liner 12, as shown in Figure 4. As shown in Figures 5 and 6, the plug 14 is reinserted into the recess 22 and the headframe 24 driven back over the shaft 10. A gear winch provided on the headframe 24 is then used to pick up the slings connected to the second shaft liner 28 and raise the second shaft liner 28 sufficiently disconnect the second shaft liner 28 from the lugs on the first shaft liner 12. The headframe 24 then lowers the second shaft liner 28 downwardly until the upper end of the second shaft liner 28 is adjacent the lower end of the first shaft liner 12.
  • the second shaft liner 28 is levelled so that the upper end thereof is level with the lower end of the first shaft liner 12.
  • the upper end of the second shaft liner 28 is provided with a plurality of longitudinal slots 32 such that the upper end may be expanded outward using a jack or other suitable device.
  • the upper end of the second shaft liner 28 is expanded outwardly until the diameter matches that of the first shaft liner 12.
  • the upper end of the second shaft liner 28 is then secured to the lower end of the first shaft liner 12 by welding. Further, the longitudinal slots 32 are welded to provided a water tight seal.
  • Figure 9 shows an alternative method of securing the upper end of the second shaft liner 28 to the lower end of the first shaft liner 12.
  • a connecting member 33 is provided.
  • the connecting member 33 comprises a tapered portion of shaft liner.
  • the connecting member 33 is tapered from a diameter equivalent to that of the first shaft liner 12 at a first end to a diameter equivalent to that of the second shaft liner 28 at a second end.
  • the connecting member 33 is provided in one or more segments to be lowered down the shaft where they are welded together to form the completed connecting member 33 and welded at the first end thereof to the first shaft liner 12 and at the second end thereof to the second shaft liner 28.
  • the second shaft liner 28 is also provided with a plurality of holes through which concrete can be poured to provide a lower concrete layer 34.
  • the lower concrete layer 34 of the second shaft liner 28 extends approximately one quarter of the way up from the lower end of the second shaft liner 28.
  • the void 36 above the lower concrete layer 34 remains empty unless poor ground conditions dictate that it be filled with concrete.
  • the headframe 24 may be used to excavate a portion of the earth under the existing shaft liner and then lower the further shaft liner down to the bottom of the excavated shaft 10 and then repeat the process until the desired depth is reached.

Abstract

La présente invention concerne un procédé pour creuser et revêtir un puits (10). Le procédé comprend l'excavation d'un puits (10) dans le sol et l'abaissement d'un premier revêtement de puits (12) à l'intérieur du puits (10), puis l'extension progressive du puits (10) vers le bas. Le puits (10) est étendu par l'excavation de la terre en-dessous du revêtement de puits existant situé le plus bas (12), et la mise en place d'un autre revêtement de puits (28) dont les dimensions lui permettent de passer à travers les revêtements de puits existants (12). L'autre revêtement de puits (28) est passé vers le bas à travers les revêtements de puits existants (12) jusqu'à ce qu'une extrémité supérieure de l'autre revêtement de puits (28) soit adjacente à l'extrémité inférieure du revêtement de puits situé le plus bas (12). Une partie de l'autre revêtement de puits (28) qui est adjacente à une extrémité supérieure, est alors étendue et fixée à l'extrémité inférieure du revêtement de puits situé le plus bas (12).
