In this embodiment, since the transverse plate 33 and the longitudinal partition plate 34 are used for being matched with the T-shaped section 31 and the section steel 32 in a splicing manner, a plurality of T-shaped grooves are arranged at intervals on one side of the transverse partition plate 33 in the width direction and are used for being matched with the T-shaped section 31; and a plurality of L-shaped grooves are arranged at intervals on the other side and are used for matching with the section steel 32, the first datum lines 100 of the transverse partition plate 33 on the two sides in the width direction are arranged at the positions of the T-shaped groove and the L-shaped grooves, and when the transverse partition plate 33 is matched with the T-shaped section 31 and the section steel 32 in a splicing manner, the transverse partition plate can be spliced according to the first datum lines 100, so that the operation is simple and convenient, and the installation precision is controllable. The distances between the four first reference lines 100 of the transverse partition 33 and the ends thereof are not limited herein, and may be selected according to the size thereof and the size and position of the T-shaped bar 31 and the section bar 32.

As shown in fig. 7, when the block 3 is spliced, the inner shell plate 35 and the outer shell plate 36 are located on two sides, the T-shaped bar 31, the section steel 32, the transverse partition plate 33 and the longitudinal partition plate 34 are arranged between the inner shell plate 35 and the outer shell plate 36 in a crossing manner, and four first reference lines 100 are used as installation references of the spliced block 3. Meanwhile, two second reference lines 200 perpendicular to each other are designed on the upper surfaces of the inner shell plate 35 and the outer shell plate 36. It will be appreciated that the first datum line 100 will be disabled after the blocks 3 are spliced, and the blocks 3 will need to be pre-assembled and the like in the subsequent steps, and the reference needs to be made through the second datum line 200 until finally the pipe joint 1 is closed. As for the drawn positions of the two perpendicular second reference lines 200, there is no limitation here, and they may be adaptively selected according to the sizes and shapes of the inner skin 35 and the outer skin 36.

In this embodiment, the bottom plate block and the top plate block of the small segment 2 have the same shape and size, and the remaining two blocks 3 are different, but the four blocks 3 are all spliced by the most basic part unit of the steel shell structure according to the first reference line 100. Because the first reference lines 100 are aligned when the parts are spliced into the block bodies 3, most of the first reference lines 100 of the parts on the spliced block bodies 3 are shielded, and at this time, when the four block bodies 3 are pre-assembled into the small segment 2, the second reference lines 200 of the block bodies 3 need to be aligned as references for pre-assembly. Firstly, taking a bottom plate block as a positioning reference block, turning over a side wall block to be normal, positioning the side wall block through a second reference line 200, and welding a butt joint of the bottom plate block and the side wall block; then hoisting the middle wall block, positioning the middle wall block and the bottom plate block by a second datum line 200, and welding the butt joint; and finally, hoisting the top plate block to the upper side, and respectively welding the top plate block with the middle wall block and the side wall block after the top plate block is positioned through the second reference line 200 to complete the pre-assembly of the small segment 2.

In this embodiment, in order to ensure the effect of folding the plurality of small segments 2, height reference lines 300 are further provided at the height positions of 3.3m of the middle wall block and the side wall block of the small segments 2, and when the plurality of small segments 2 are folded, the height reference lines 300 of the small segments 2 are also aligned, so that the precision of assembling the pipe joint 1 is further ensured. In other embodiments, the position of the height reference line 300 may also be adaptively adjusted.
The embodiment also provides a steel shell pipe joint of the immersed tunnel, which is manufactured by adopting the manufacturing method of the steel shell pipe joint of the immersed tunnel. As shown in fig. 10, the length of the steel shell pipe section of the immersed tunnel is 165m, the width is 46m, the height is 10.6m, and the immersed tunnel is divided into 11 small sections 2 with the length of 15m in the length direction, and then the width direction is divided into 22 small sections 2 according to the principle of left-right substantially symmetrical division. Specifically, when the small sections 2 are divided, the scale of the small sections 2 is divided as large as possible so as to reduce the hoisting times of the overall assembly of the platform lines on the small sections 2 and improve the overall assembly efficiency; meanwhile, the principle of convenient manufacture is considered, and the front and the back of the small segment 2 are divided into the same structural form. In other embodiments, the size of the steel shell pipe section of the immersed tunnel can be adjusted adaptively, and the number of the divided small sections 2 can be increased or decreased appropriately.
