Problems solved by technology
[0002] The traditional large-diameter segmented, diameter less than φ10000mm, large-diameter composite tube, the general construction method is to assemble the large-diameter composite tube upright, weld, and then turn over the segments and close them, although this method can The composite cylinder is built in sections, but the efficiency is relatively low, and the submerged arc automatic welding cannot be effectively used
The main reason for the low efficiency of this method is that the efficiency of the vertical assembly of the cylinder section is relatively low, and the efficiency of welding the circular seam is lower. Because the vertical assembly cannot use submerged arc welding, only carbon dioxide gas shielded welding can be used, and the assembly and welding efficiency is very low. , the processing period is longer

[0029] like Figure 1 - Figure 5.4 Shows a specific embodiment of the present invention provides a method of construction of large diameter pile composite cartridge: comprising the steps of:
[0030] Sl, cylindrical shell made of: A composite cylinder divided into a front section, the rear section C and the section B, the size of each segment in accordance with the material and cut the steel plate, and each plate roll round steel plate welded into circularly cylindrical section, wherein the B segment consists of segments B1 and B2 composed of segments;
[0031] S2, and set the wheel frame welding holder: As the current team and the maximum diameter of the welding machine frame may be used in the range of 10m, the diameter of more than 10m, the safety wheel angle of less than 45 degrees, so in order to apply a diameter greater than 10m, the first the need to weld frame and wheel frame heightening widening treatment (e.g. figure 1 Shown), welding the supporting structure, both sides ...

The invention discloses a construction method of a super-large-diameter single-pile composite cylinder. The construction method comprises the following steps: S1, manufacturing cylinder sections; S2, arranging a roller frame and a welding frame; S3, performing longitudinal stitching; S4, forming a team; S5, manufacturing a first platform; S6, closing the middle section B and the rear section C; S7, shifting; S8, manufacturing a second platform; S9, arranging a roller carrier; S10, carrying out large folding; S11, checking the straightness; and S12, coating. The horizontal manufacturing method is adopted, the assembling time of pipe joints can be effectively saved, submerged arc automation can be used, the production efficiency is improved, and the production time is saved.
Description
Technical field [0001] The present invention belongs to the technical field of wind power equipment, particularly relates to a method for the construction of floating wind power for the base of the large diameter cylinder of the composite pile. Background technique [0002] Conventional large diameter segment, diameter less than φ10000mm, large diameter composite tube, generally requires construction methods for the large-diameter tubular composite stands for assembly, welding, and then turn over the segment, collapse, although this method may be the construction of the composite tube segment out, but the efficiency is relatively low, it can not effectively use the submerged arc welding. This method, mainly due to the low efficiency of the vertical tubular section assembly efficiency is relatively low, and lower efficiency girth welding, assembly can not be used due to the vertical submerged arc welding using only carbon dioxide gas welding, the welding and assembling efficiency ...
