Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all belongs to the scope of protection of the invention.
As shown in Figure 1, be the specific embodiment of the construction process of wind-power generating unit tower provided by the invention, comprise:
Step 11, at the outer wall welding shear key of steel tower tube section and/or the array of shear stud.
Due to the maximization of wind power generating set, the height of pylon is more and more higher, its shear stress born is increasing, therefore while steel tower tube section makes, welds shear key, shear stud or the combination of the two at its outer wall, and forms an array on the outer peripheral face of steel tower tube section.And steel tower tube section is generally be rolled into by steel plate, therefore, steel plate welds shear key or shear stud is convenient and easy.On the steel plate that shear key adopts thicker channel-section steel to be vertically welded in for making steel tower tube section, on the steel plate that shear stud adopts the bolt of existing specification to be vertically welded in for making steel tower tube section.
Wherein, the array of shear key and/or shear stud is triangle or rectangle, and namely each shear key and the shear stud shape that cloth postpone is formed on the steel plate being used for making steel tower tube section is triangle or rectangle.Specifically determine according to shear key and the size of shear stud and the wall thickness of steel tower tube section.
Preferably, the length that shear stud gives prominence to steel tower tube section outer wall is more than or equal to 30mm and is more than or equal to 4 times of the peg shank diameter of shear stud.
Secondly, the spacing in the vertical direction of adjacent shear stud is more than or equal to 6 times of described peg shank diameter, in level or be circumferentially more than or equal to 4 times of peg shank diameter.
Step 12, outer wall gunning concrete layer in steel tower tube section.
By the outer wall gunning concrete layer in steel tower tube section to increase pylon wall thickness and external diameter, thus improve the rigidity of pylon.Wherein the thickness of layer of concrete is greater than the length that shear key and/or shear stud protrude from steel tower tube section outer wall, with the array making layer of concrete cover whole shear key and/or shear stud, avoids getting rusty because shear key and/or shear stud expose.Wherein the outermost end of layer of concrete protrudes from the distance of the end of steel tower tube section outer wall to shear key and/or shear stud is topping, and the thickness of this topping should meet Standard.
Because layer of concrete and steel tower tube section are two kinds of different materials, the effect of shear key and shear stud makes the two cooperative bearing and is unlikely to produce slippage because of shear stress, causes layer of concrete to peel off from steel tower tube section.
And concrete material is much lower relative to the cost of steel, and the technique of gunning concrete can be constructed at the scene, avoids the problem due to the too large inconvenience long-distance transport of size.
Step 13, steel tower tube section is coupled together formation pylon in the height direction.
