[0002] The bottom plate and top plate of the pile shoe are linear, thick (there is a difference in plate thickness), have many plate seams, and a large amount of welding for the panels.

[0122] 4.2. Panelization of Section E bottom plate 408:

[0123] A slow welding zone 409 is set in the middle between the E-section one plate 402 and the E-section two plate 403. The E-section one plate 402 and the E-section two plate 403 are firstly automatically welded and the welding area is the left and right sides of the slow welding zone 409. The slow welding zone 409 is not welded. Then, cold working is performed to form a large plate 404 of the E-section.

The overall weight after the panels are assembled is overweight, which does not meet the relevant requirements of the cold processing equipment. After planning, the panels are assembled in two parts. The E-section second large plate 405 is a separate plate and is cold processed first. There is an E-section first plate seam 411 in the E-section large plate 404, and the E-section first plate seam 411 For the cross-E section processing line 410, one branch plate 402 and two branch plates 403 of one large plate 404 of section E can be spliced ​​first, and a 300mm slow-welding zone 409 can be left at the E section processing line 410 to avoid the weld being cold processed. After cold processing, one large plate 404 and two large plates 405 of section E can be spliced ​​by submerged arc automatic welding. The 300mm long slow-welding zone 409 is oxygen welded, which can meet the capacity of the cold processing equipment and realize submerged arc welding splicing.
