Definitions

  • the present invention relates to hollow concrete towers formed with precast pieces, especially but not exclusively, such as those used in wind turbines and more in particular to a mounting method and a mounting device thereof.
  • WO 03/069099 describes a tower structured by a set of sections formed by several precast pieces where vertical tensor cables are used as primary attachments means of the precast pieces.
  • WO 2006/111597 describes a tower structured by a set of precast pieces of reduced thickness stiffened by an internal structure of horizontal and vertical ribs where horizontal and vertical tensor cables are used as attachments means of the precast pieces.
  • wind turbine towers can be located in places difficult to be accessed by cranes capable of lifting heavy loads to great heights.
  • the present invention is directed to solving that problem.
  • An object of the present invention is to provide a mounting method of a hollow tower without using a conventional crane and a tower mounted by this method, the tower being structured in a plurality of vertical sections formed by several precast pieces.
  • Another object of the present invention is to provide a mounting device of a hollow tower structured in a plurality of vertical sections formed by several precast pieces.
  • Said mounting device according to the invention comprises:
  • the method of the invention is applicable to any hollow tower structured in a plurality of vertical sections formed by several precast pieces in which the attaching means of the precast pieces are accessible through the interior of the tower.
  • the tower is structured in a plurality of vertical sections formed by several precast pieces, configured with outer and inner walls, upper and lower horizontal bases and side walls, comprising on the one hand interlocking means and on the other hand an anchoring element embedded in the inner wall having an upper conduit and a lower conduit for the passage of tensor cables.
  • the joining operations of the concrete precast pieces consist of, on one hand, on the sealing of the interlocking means of the concrete precast pieces located on two adjacent vertical sections with a grout which is poured through a hole accessible from the interior of the tower and, on the other hand, joining each concrete precast piece of a vertical section to the adjacent concrete precast pieces of the lower section by passing a tensor cable by, respectively, their upper and lower conduits and forming with it a tensioning ring that joins the precast pieces of two adjacent vertical sections.
  • the above mentioned objects are achieved with a tower comprising the tower mounted by the mentioned method and the auxiliary tower used in the mounting.
  • the auxiliary tower provides an access means both to the interior of the tower and to the nacelle and turbine blades to perform maintenance tasks.
  • a mounting device comprising:
  • the tower (Figs. 1-5)
  • the tower 11 of the invention is a tower structured in vertical sections 13, each section being formed by several precast pieces 15.
  • the precast pieces 15, configured with outer and inner walls 51, 53, upper and lower horizontal bases 57, 55 and side walls 59, 61, have, preferably, a dowel shape as illustrated in Figures 1a, 1b and are made with high strength concrete and inner steel bars 16.
  • the tower 11 may have a frusto-conical or cylindrical shape as illustrated in Figures 4a and 4b .
  • all the vertical sections 13 have the same diameter while in the first case they have different diameters and different number of precast pieces 15 at different vertical sections 13, for example 6 precast pieces in the first vertical section and 2 precast pieces in the last vertical section.
  • the height of the precast pieces 15 is comprised between 1.2 - 3m and the ratio width/height is greater than 2. They are therefore precast pieces 15 of a relatively small size.
  • the tower 11 is structured with the precast pieces 15 of each vertical section 13 mounted staggered with respect to the pieces of the lower section (see Figure 5 ) and joined by two attachment means: on the one hand, interlocking means as vertical attachment means between the precast pieces 15 of a vertical section 13 with the precast pieces of the lower vertical section; on the other hand tensor cables 17 to link together by the inside the tower 11 the precast pieces 15 of a vertical section with the adjacent precast pieces of the lower section.
  • the interlocking means comprise two female recesses 31, 33 and two male inserts 35, 37 located respectively on the lower and upper bases 55, 57 of the precast pieces 15.
  • the male inserts 35, 37 are made of steel and configured with a cross-shaped head 36 and a shank 40 which is screwed into a sheath 41 embedded in the precast pieces 15.
  • the joints between male inserts 35, 37 and female recesses 31, 33 are filled with slurry of high strength concrete which is poured through holes 39 (see Figure 2 ).
  • Male inserts 35, 37 absorb part of the shear stress to which the tower 11 is subjected and the staggering of the precast pieces 15 of a vertical section 13 of the tower 11 with respect to the precast pieces 15 of the lower vertical section implies that the two female recesses 31, 33 of a precast piece 15 engage with the male inserts 37, 35 of two different precast pieces 15 of the lower vertical section thereby enhancing the strength of the tower 11.
  • the precast pieces 15 comprise anchoring elements 21 for tensor cables 17 which are embedded in the precast pieces 15 by their inner wall 53.
  • These anchoring elements 21 comprise an upper conduit 23 and a lower conduit 25 for the passage of tensor cables 17.
  • a tensor cable 17 passes through the upper conduits 23 of the precast pieces 15 of the central vertical section 13 and through the lower conduits 25 of the precast pieces 15 of the lower section and another tensor cable 17 passes through the lower conduits 25 of the precast pieces 15 of the central vertical section 13 and by upper conduits 23 of the precast pieces 15 of the upper section.
  • the upper and lower conduits 23, 25 are located at a different distance from the inner wall of the precast pieces 15 (contrary to the embodiment shown in Figure 3 ). With this provision, the tensor cables 17 allow "tying" two vertical sections 13 of the tower 11.
  • the tensor cables 17 by, for example, a portable electric tensioning pump or a portable mono-cable tensor they are arranged in the form of a ring which starts and ends at the same point in which is placed a double cone terminal (a cone for the start of the cable and other for the ring closure).
  • the mounting device of the tower (Figs. 6-9)
  • the mounting device of the tower 11 is formed by an auxiliary tower 12, a deliverer platform 27 and a mounting gateway 19.
  • the auxiliary tower 12 comprises a primary module 14 formed by a lattice of metal bars and additional modules 26 that are assembled to the auxiliary tower by its base in the lifting steps of the auxiliary tower 12. Additional modules 26 are formed by a lattice of metal bars divided in two parts to facilitate its assembly in each lifting step of the auxiliary tower 12 as will be discussed below.
  • the deliverer platform 27 that is coupled to the top of the auxiliary tower 12 so that it can rotate 360 degrees about it, comprises a box girder 71 of great inertia with two hoists 73, 75 at their ends provided with an engine power appropriate for the structure of the tower 11 which are arranged for hoisting (more particularly raising) two precast pieces 15 simultaneously to give balance to the system. It also comprises four auxiliary arms 77 intended to control that the precast pieces 15 are maintained in their position until they are joined to other precast pieces 15 by the tensor cables 17.
  • FIG 9c shows one possible embodiment of the invention in which each one of the hoists 73, 75 comprise trolleys 80 provided with rollers 81 in contact with the box girder 71, said rollers 81 are provided with a movement mechanism (not shown in the figures) which, when operated, make the rollers 81 rotate and consequently forces the trolleys 80 to move along the main direction of box girder 71 to a certain desired position.
  • the engine (and consequently the hook 84 which is attached to the wire 83), can slide along the intermediate member 82, for example by means of a first pinion rack arrangement 85, to obtain a more precise positioning of the hoist 73, 75.
  • the sliding movement of the engine and hook 84 along the intermediate member 82 is represented in figure 9c with dotted lines.
  • An additional rack 86 can be disposed at the bottom part of the box girder 71 and additional pinions (not shown) can be provided in the trolleys 80 to form a second pion rack arrangement intended to smooth the movement of the trolleys 80 along the box girder 71.
  • hoist 73, 75 (and more precisely of the hook 84) is necessary for mounting towers in which the diameter of the vertical sections 13 vary with height, for example the frusto-conical tower shown in Fig. 4a .
  • Auxiliary arms 77 can be optionally provided at their ends with hoists 73, 75, substantially identical to those described in connection with the box girder 71.
  • the mounting gateway 19 comprise several radial telescopic beams 79 which can be retracted during the lifting of the auxiliary tower 12 to conform to the inner surface of the tower 11.
  • Above the telescopic beams 79 will slide several stretches of "tramex" type, formed by a lower bearing part and an upper part. They are 10cm wide stretches, which are attached by pins in a hinge mode. When receding the telescoping beams 79 the stretches will fall one by one, applying a delay to the telescopic beams 79 in order to avoid that they hit between them.
  • the mounting gateway 19 structured in three pieces, allow operators perform various operations for joining the precast pieces 15 during the mounting process of the tower 11.
  • the auxiliary tower 12 together with the mounting gateway 19 will remain in the interior of the tower 11 after its mounting as it can be used to hold the ladder and other equipment.
  • a first step the primary module 14 of the auxiliary tower 12 is mounted in the center of the intended location for the tower 11 on a base 10 with the deliverer platform 27 coupled to its top and the mounting gateway 19 fitted in a position close to its lower base.
  • Figure 10e shows the mounting device arranged at the appropriate height for initiating a cycle after the mounting of four vertical sections of the tower 11.
  • Figure 10f shows the deliverer platform 27 of the mounting device lifting two precast pieces 15.
  • Figure 10g shows the deliverer platform 27 of the mounting device placing two concrete precast pieces 15 over the last section of the tower 11.
  • this step is performed as illustrated in Figures 11a-11i lifting a pair of precast pieces 15 from particular locations outside of the tower 11 and rotating the deliverer platform 27 to place them in their proper position over the last section of the tower 11.
  • This embodiment of the mounting method is applicable to a tower 11 structured with an even number of precast pieces 15 in each vertical section 13.
  • Figures 10h-10j illustrate the first step of the cycle mentioned.
  • Figure 10h shows the auxiliary tower 12 arranged to rise on the height of a vertical section 13 of the tower 11 by using stabilizer arms 18, 18' supported on the vertical sections 13 of the tower 11 already mounted.
  • Figure 10i shows the auxiliary tower 12 in its new position.
  • the elevation is performed by a hydraulic or an electric system.
  • Figure 10j shows the auxiliary tower 12 with a new additional module 26 assembled thereto.
  • Figure 12 is a schematic elevation view of the lifting of precast pieces 15 during the placing of said precast pieces 15 over the last section of the tower (step d), according to an alternative embodiment of the of the mounting method of the invention, in which precast pieces to be raised are provided with stabilizer wheel arrangements 90 in order to slide along the external walls of the vertical sections 13.
