Embodiment Construction
[0026] Such as Figure 7 The process shown, refer to Figure 8 Illustrate the installation method of the whole cantilever beam of the present invention dragged to the platform, including the following steps:
[0027] Step 1. Independently construct the upturned part of the track in the glide path at the bow end of the cantilever beam. attached figure 1 It is a cantilever beam lower track structure built separately in the open area of the bow (upward warping slide track), and the structure is machined as a whole after all welding work is completed. The structure mainly includes the main structures such as the lower sliding track panel 1, the main vertical plate 2 and the V-shaped plate 3.
[0028] Step 2. After the cantilever beam is built as a whole on the bank, the upturned part of the track is horizontally sealed at the installation position of the cantilever beam with fixing parts. At this time, there is a gap between the upturned part of the track and the cantilever b...
