Definitions

  • the present invention relates to a method and an apparatus for constructing long span, shell-shaped, substantially horizontal concrete structures.
  • the invention relates to shell-shaped concrete structures which are utilized in constructing submerged tubes (bridges, tunnels), pipe bridges and floating bridges, but also in general where such long span, shell-shaped, substantially horizontal concrete structures are utilized, and where the requirements to homogenity, water-tightness and strength are important.
  • shell-shaped concrete structures are assembled by prefabricated elements which are constructed by known methods, for example constructed in a floating vertical position by conventional slip-forming methods, eventually constructed in a dry dock or at a construction site (yard), whereafter the elements are transported to the final construction site and assembled.
  • the assembly of the elements is carried out, for example by means of bolts for pulling the elements together, and thereafter by using prestressing cables for tightening the elements together.
  • the known methods can be applied on the assumption that sufficient water-tightness and strength are achieved in the joints.
  • the joint between the elements is a weak part in relation to both strength and water-tightness.
  • Experience has shown that such joints have a tendency to leak, and thereby increase the maintainance costs. Therefore, these joints must be considered as undesirable elements regarding the overall strength of the structure.
  • such long span, shell-shaped, substantially horizontal concrete structures are constructed as a continuous (homogeneous) concrete structure without joints.
  • the problem related to the water tightness of the joints is avoided and a substantial increase in strength of the structure is achieved because the joints between the reinforcement bars of the structure are not located at certain locations, which is the case for conventional methods utilizing prefabricated elements, and in addition the joints for joining the prestressing cables together can be distributed over the complete length of the structure.
  • Another substantial advantage of the solution is that no elements or the like transversally perforate the concrete wall, hence the risk for leakage is avoided.
  • the shell-shaped, substantially horizontal concrete structures are continuously constructed in an approximately horizontal position and by means of a number of longitudinal movable formwork modules, each comprising at least two outer and two inner formwork elements.
  • the present method is characterized in that the concrete structure is constructed in a continuous casting process by applying a substantially horizontal formwork apparatus with continuous supplying of fresh concrete with suitable consistency and by establishing, in relation to the horizontal plane, a free rearwardly inclining freely exposed casting surface.
  • the method comprising the steps of applying a completely or partly displacable and removable formwork unit comprising a plurality of - in the operation mode - mutually joined formwork modules which sequentially and repeatedly are moved from the front end of the formwork to the rear end of the formwork, the concrete structure together with the formwork unit being moved forward in conformity with the curing speed of the concrete at the front end of the formwork, until the complete concrete structure has achieved a desired length.
  • the operation is carried out in a continuous process with inclined casting surface, in which fresh concrete is supplied all the time.
  • Reinforcing bars and ducts for prestressing cables are installed in front of the casting surface.
  • the installation and tightening of the prestressing cables are carried out in a known manner from recesses in the wall after the formwork elements are removed. New cable lengths are connected to already prestressed cables and thereafter prestressed. After prestressing, the cables are grouted and the recesses are closed by concreting.
  • tunnels are built up by prefabricated elements 1, 2, see Fig. 1.
  • the elements are towed to the installation site, and joined together by bolts and sealed with a rubber sealing 3 as a first sealing and joint, whereafter the recess 4 is filled with concrete.
  • the production apparatus mainly consists of, as shown in Figs. 2a-c and 3a-f, a base 23, a skid 24, a number of formwork modules 18 comprising outer formwork elements 6-11 and inner formwork elements 12-17, a support beam 2 with the first end supported on a support frame 20 and the second end on a temporary support 28 prior to casting of the first module, thereafter inside the cured part of the concrete structure 32.
  • the formwork elements 6-17 are mounted together behind the curing surface (in front of support frame 20) and they are demounted in a demounting pit 30 located in the front end of the structure.
  • the tube is constructed in accordance with the following method:
  • the method is coat efficient, due to the fact that pulling (skidding) of the structure, concreting with the inclined casting surface and the prestressing operation can be carried out as independent operations.
  • the above example describes an apparatus in which six inner and six outer formwork elements are utilized, but an mentioned above, two inner and two outer formwork elements can be used. Further, instead of using inner/outer movable formwork elements, it is possible to utilize prefabricated tubes or tube sections which are mounted together to form a later permanent inner/outer lining of the structure.
  • the preferred embodiment of the invention describes a circular, tube-shaped structure, however the method can be applied in constructing for example rectangular open semi-circular structures, etc.
