In some embodiments of the present invention, as shown in fig. 1-2, the peripheral wall of the first connecting plate 120 exceeds the peripheral wall of the main body column 110, so that, in the case that the main body column 110 is small in volume, the first connecting plate 120 can be connected to the upper fork column 200 with a large volume, so that the upper fork column 200 can be connected to the bridge structure 2000 with a large volume, and the problem that the bridge structure 2000 needs to be erected in a small ground environment can be solved. A plurality of sixth reinforcing plates 143 are disposed between the first connecting plate 120 and the main body column 110, the plurality of sixth reinforcing plates 143 are spaced apart in the circumferential direction of the main body column 110, the upper end of the sixth reinforcing plate 143 is connected to the first connecting plate 120, and the end of the sixth reinforcing plate 143 near the center of the main body column 110 is connected to the outer circumferential wall of the main body column 110.

The poured lower pier stud 100 has better structural strength, better pressure resistance and better durability.
The process steps for manufacturing the lower pier 100 are described below with reference to fig. 1-2:
the method comprises the following steps: welding the third reinforcing plate 130 to the inner side of the main body column 110, for example, a double-sided fillet weld may be used to connect the third reinforcing plate 130 and the main body column 110;
step two: the fourth reinforcing plate 141 and the fifth reinforcing plate 142 are welded to the bottom surface of the first connecting plate 120, the upper end of the fourth reinforcing plate 141 is welded to the lower surface of the first connecting plate 120, and the fifth reinforcing plate 142 is welded to the lower end of the corresponding fourth reinforcing plate 141, whereby the fourth reinforcing plate 141 and the fifth reinforcing plate 142 form an inverted T-shaped structure, the number of which may be 4, and there is no particular limitation. The inverted T-shaped structures are evenly distributed around the center of the first connecting plate 120 to increase the rigidity of the first connecting plate 120;
step three: the first connecting plate 120 is placed on top of the main body post 110, the first connecting plate 120 is rotated to shift the inverted T-shaped structure from the third reinforcing plate 130, as shown in FIG. 2, and then the joint of the first connecting plate 120 and the main body post 110 is welded, where it can be integrally welded by all penetration or the like.
Step four: welding the sixth reinforcing plate 143 outside the main body column 110, wherein the parts of the sixth reinforcing plate 143 connected with the first connecting plate 120 and the main body column 110 are welded, and double-sided fillet welding can be adopted;
step five: the body column 110 and the sixth reinforcing plate 143 are wrapped by the collar 144, and the collar 144 is welded to the outer side of the sixth reinforcing plate 143, wherein the collar 144 can be welded to the outer side of the sixth reinforcing plate 143 by a single-sided fillet weld;
step six: a material with good compressive strength and durability, such as concrete, is poured through the pouring holes 121 of the first connecting plate 120.
The process steps for manufacturing the upper cross columns 200 of the pier 1000 are explained below with reference to fig. 4 to 13:
the method comprises the following steps: the intersecting part of the first pillar 211 and the third pillar 213 is cut off, and then the intersecting part is welded completely, for example, strong welding such as penetration welding can be adopted;
step two: the intersecting portion of the second pillar 212 and the fourth pillar 214 is cut off, and then the intersecting portion is welded, for example, a strong welding such as penetration welding;
step three: intersecting the connecting whole of the first support column 211 and the third support column 213 with the connecting whole of the second support column 212 and the fourth support column 214, cutting off the connecting whole of the second support column 212 and the fourth support column 214, and then welding the intersecting part completely, for example, through-fusion welding or other strong welding can be adopted;

In the splicing step of the upper fork column 200, the sequence of cutting and welding the first column 211 and the third column 213, and the second column 212 and the fourth column 214 in the first step and the second step can be replaced by the sequence of cutting and welding any two adjacent columns 210, but the sequence of cutting and welding any two adjacent columns 210 cannot be replaced by the sequence of cutting and welding two opposite columns 210. It can be understood that any two adjacent pillars 210 are respectively cut and welded so that the central lines of the roots of the pillars 210 are not all intersected at one point, but are still symmetrical left and right or symmetrical up and down, therefore, during production, the pillars 210 can be spliced up and down and then spliced left and right, or spliced up and down and then spliced left and right, and the difficulty of construction can be reduced. The diagonal splicing precision is difficult to guarantee, the construction is complex, and the overall connection strength of the 210 struts is poor.
