Embodiment 1
[0038] Such as Figure 1 to Figure 3 As shown: the integral abutment based on corrugated steel plates in this embodiment includes a box girder and several abutment foundations 4 for supporting the box girder. The box girder includes a concrete roof 2, a concrete bottom 3 and a corrugated rigid web. The slabs are respectively connected to the concrete top slab 2 and the concrete bottom slab 3; the end of the corrugated steel web is connected to the abutment foundation 4 through the corrugated steel plate group, and the bottom end of the middle part of the corrugated steel web 1 extends downward and is inserted into the pier 6. In this embodiment, the corrugated steel plate group includes only one corrugated steel plate 5 .
[0039] The box girder includes at least two corrugated steel webs 1, and the corrugated steel webs 1 are connected with the concrete top plate 2 and the concrete bottom plate 3 of the box girder through perforated steel plates and / or welding nails to form a...
Embodiment 2
[0053] Such as Figure 4 As shown, this embodiment provides an integral abutment based on corrugated steel plates. Compared with Embodiment 1, the difference lies in that the corrugated steel web 1 of the box girder in this embodiment corresponds to the corrugated steel plate group of the abutment It includes two or three corrugated steel plates 5 parallel to each other.
Embodiment 3
[0055] Such as Figure 5 As shown, the difference between the present embodiment and the first embodiment is that: the corrugated steel plate 5 in the present embodiment is provided with a vertical stiffener 10, and the stiffener 10 is a plate rib or a T rib.
