Embodiment Construction
[0012] like Figure 1-2 Shown, a kind of flexible wall anti-seismic abutment of the present invention consists of vertical pile 1, inclined pile 2, pile cap foundation 3, support beam 4, enlarged bridge deck 7, reinforced concrete flexible anti-seismic wall 9, anti-seismic joint 10, Composed of box-shaped retaining wall 12 and expanded polystyrene board 11; the bridge deck slab on the span structure 6 of the bridge is extended to the abutment to form an enlarged bridge deck 7, and directly connected with the road deck to form a road-bridge joint 8 , there is no expansion joint between the bridge abutment and bridge span structure 6; vertical piles 1 and inclined piles 2 support the pile cap foundation 3 of the abutment, this foundation form has a large bearing capacity and good stability, and can avoid foundation slippage that may occur in earthquakes Move and turn. On the pile cap foundation 3, there are fixed support beams 4, five reinforced concrete flexible shock-absorbin...
