Abstract
The invention relates to a slipform concrete structure (12), and a method of operating a slipform apparatus (10) for constructing a slipform concrete structure (12). The slipform apparatus (12) comprising a platform (10) and a lift device. The method includes performing a concrete slipform operation comprising pouring concrete and raising the platform using the lift device to construct the slipform concrete structure, and performing an excavation operation comprising removing material from underneath or one side of the slipform concrete structure (12) so that the structure lowers under the action of gravity.
Claims (27)
1. A method of operating a slipform apparatus for constructing a slipform structure, the slipform apparatus comprising a platform and a lift device, the method including: performing a concrete slipform operation comprising pouring concrete and raising the platform using the lift device to construct the slipform structure; and performing an excavation operation comprising removing material from underneath or one side of the slipform structure so that the slipform structure lowers under the action of gravity.
2. A method according to claim 1, and further including performing the concrete slipform operation at the same time as performing the excavation operation.
3. A method according to claim 1, and further including stopping the concrete slipform operation, waiting until the concrete has set, and then performing the excavation operation.
4. A method according to claim 3, and further including repeating the concrete slipform operation on top of the section of the slipform structure, and repeating the excavation operation.
5. A method according to any preceding claim, wherein the platform has at least one work level around a perimeter of the platform that surrounds a central space through the at least one work level, the method further including: said excavation operation comprising removing material via an open mouth of the slipform structure.
6. A method according to any preceding claim, and further including providing the slipform structure with a cutting edge at a base thereof prior to performing the concrete slipform operation on top thereof
7. A method according to claim 6, and further including providing the cutting edge as a taper on one side of the slipform structure to push material to one side thereof as it lowers under the action of gravity.
8. A method according to claim 7, when dependent on claim 5, and further including providing the taper so that the material is pushed radially inward of the central space
9. A method according to any preceding claim, and further including providing the slipform structure with a capping structure adjacent thereto prior to performing the concrete slipform operation, wherein the platform is above the capping structure and has a part thereof for preventing the platform from moving below the capping structure .
10. A method according to claim 9, when dependent on any of claims 6 to 8, and further including placing the cutting edge with the capping structure adjacent thereto prior to performing the concrete slipform operation.
11. A method according to any preceding claim, and further including providing the slip form structure with a support adjacent thereto prior to performing the concrete slipform operation .
12. A method according to claim 11, when dependent on any of claims 9 or 10, and further including forming the support with the capping structure prior to performing the concrete slipform operation.
13. A method according to any of claims 6 to 8, when dependent on any of claims 9 or 10 and any of claims 11 and 12, and further including forming the capping structure so that it is outermost of the slipform structure, and forming the support so that it is innermost of the concrete structure, wherein the cutting edge is placed between the capping structure and the support .
14. A method according to claim 13, and further including separating the cutting edge from the capping structure and the support using shuttering during forming thereof
15. A method according to any of claims 11 to 14, and further including removing the support when performing the excavation operation.
16. A method according to any preceding claim, and further including performing a lift device installation operation comprising: installing one or more jack rods into the slipform structure, the lift device comprising one or more jacks that operate on the one or more jack rods to raise the platform; or installing one or more cables and winches for the lift device suitable for raising or lowering the platform.
17. A method according to any preceding claim, wherein the platform has a plurality of work levels, the method further including using one level to perform one operation, and using another level to perform another operation.
18. A method according to claim 17, wherein said concrete slipform operation further includes using one of the plurality of work levels for pouring of the concrete, and another of the plurality of work levels to finish the set concrete .
19. A method according to any preceding claim, and further including assembling the platform above ground prior to operation thereof.
20. A method according to any preceding claim, and further including installing a foundation underneath the slipform structure after completion thereof.
21. A method according to any preceding claim, and further including performing a reinforcement operation of the slipform structure comprising: performing a rebar installation operation of the slipform structure comprising installing at least one rebar cage; and/or using fibre concrete for the concrete slipform operation.
22. A method according to claim 21, when dependent on claim 17, wherein said rebar installation operation further includes using one of the plurality of work levels to install vertical reinforcing bars, and another of the plurality of work levels to install horizontal reinforcing bars.
23. A method according to any preceding claim, and further including using a slurry agent to assist with lowering of the slipform structure under the action of gravity.
24. A slipform structure produced using the method of any of claims 1 to 23.
25. A slipform structure comprising a cutting edge at a base thereof, the cutting edge having a taper on one side of the slipform structure for pushing material to one side thereof as it lowers under the action of gravity.
26. A slipform structure according to claim 25, and further including a capping structure adjacent thereto, wherein a platform to form the slipform structure is above the capping structure and has a part thereof for preventing the platform from moving below the capping structure.
27. A slipform structure according to claim 26, and further including a support adjacent thereto, wherein the capping structure is outermost of the slipform structure, the support is innermost of the concrete structure, and the cutting edge is between the capping structure and the support.
