[0035] Example 1

[0036] like Figures 1 to 3 As shown, this embodiment provides a V-shaped pier structure, including a V-shaped pier 1, a connecting beam and a pier cap 4. The V-shaped pier 1 is an inverted trapezoidal structure. The V-shaped pier 1 is installed on the pier cap 4. The end of the V-shaped pier 1 away from the pier cap 4 is provided with a V-shaped groove. The connecting beam is fixed on the V-shaped pier 1 and erected on the V-shaped groove.

[0037] This design utilizes V-shaped piers 1, with a V-shaped groove at the upper end of the piers 1, upon which connecting beams are installed. This simplifies the overall bridge structure and ensures reliable quality. Compared to conventional pile-and-column pier cap beams, the V-shaped piers 1 offer a more concise and aesthetically pleasing design, and the V-shaped grooves significantly save space beneath the bridge.

[0038] Specifically, the V-shaped groove divides the V-shaped pier 1 into a symmetrically distributed first support column 11 and second support column 12. The side of the first support column 11 and the second support column 12 away from the V-shaped groove is a straight sidewall that slopes away from the V-shaped groove.

[0039] Among them, the connecting beam is a variable height tie beam 2, which is installed in a V-shaped groove. One end of the variable height tie beam 2 is connected to the first support column 11, and the other end is connected to the second support column 12. The upper ends of the first support column 11 and the second support column 12 are respectively provided with main bridge support pads 13.

[0040] Specifically, the variable-height tie beam 2 has a straight section at the end away from the bottom of the V-shaped groove, and an arc-shaped section at the end near the bottom of the V-shaped groove, with the arc-shaped section concave in the direction away from the bottom of the V-shaped groove. T-shaped reinforcing ribs are provided on the opposite sides of the first support column 11 and the second support column 12.

[0041] In the embodiment, the pier is a V-shaped reinforced concrete structure, the outer profile is a slanted straight line, and the inner profile is a spline curve, which is beautiful in shape and can be applied to the bridge type structures of the main bridge, such as the arch tower cable-stayed bridge, the arch tower suspension bridge and the arch bridge; the line shape of the spline curve can be adjusted according to the height and width of the pier and echo the shape of the tower and the main arch of the main bridge; when the main bridge and the approach bridge adopt the integral box girder, the V-shaped pier structure is adopted for the main bridge auxiliary pier, the transition pier and the approach bridge pier, and the variable height bent cap is adopted at the top to balance the horizontal component.

[0042] Embodiment 2

[0044] Among them, the two ends of the side of the variable height bent cap 3 away from the V-shaped pier 1 are respectively provided with bent cap stoppers 31, and a plurality of approach bridge support pads 32 are arranged between the bent cap stoppers 31.

[0045] Further, as shown in Figures 7 to 9 , the upper end of the variable height bent cap 3 is provided with an L-shaped step, the L-shaped step includes a first support surface and a second support surface, and the second support surface is higher than the first support surface.

[0046] Among them, the first support surface is provided with a plurality of main bridge support pads 13, and each main bridge support pad is located directly above the first support column 11 and the second support column 12. The two ends of the second support surface are respectively provided with bent cap stoppers 31, and a plurality of approach bridge support pads 32 are arranged between the bent cap stoppers.

[0047] In the embodiment, when the approach bridge upper structure adopts the prefabricated assembly type small box girder, T girder and composite girder, the main bridge and the approach bridge transition pier and the approach bridge pier still adopt the V-shaped pier, and the top adopts the prestressed reinforced concrete large cantilever bent cap, which can place the assembly type upper structure of multiple bearings while balancing the horizontal component. The scheme is simple and beautiful in shape compared with the conventional pile column type pier bent cap, and can greatly save the space under the bridge.
