Abstract
The utility model discloses an anti-slide arch bridge base side pier, n (n >= 8) rigid inclined piles which are arranged in quincunx shapes are positioned under the reinforced concrete bottom board ofa traditional arch bridge pier, the ratio L / D of pile length L and pile diameter D ranges from 1.5 to 2.5, the slope angle theta of the pile is greater than zero degree, the ratio of the pile center distance alpha and the pile diameter ranges from 2.5 to 3.5, forced longitudinal steel bars in the piles are only arranged at tensile sides in the range of 150 degrees, and constructional steel barsare only arranged in other ranges. The anti-slide arch bridge base side pier greatly enhances the horizontal-slide resistant bearing capacity of traditional side piers through the arrangement of rigid inclined pile groups.
Description
Technical field
It is honest to the utility model discloses limit, a kind of antiskid moving arch bridge basis.
Background technology
Arch type bridge is one of structural shape of a kind of not only attractive in appearance but also economic security, but when on soft foundation, building arch bridge, the anti-horizontal slip ability of abutment pier of conventional method design is lower, the reinforced concrete pile of traditional design pile foundation is a flexible pile, though have very high vertical bearing capacity, but anti-horizontal slip ability is not high yet, and two kinds of methods all are difficult to meet design requirement, even has restricted the application of arch bridge on soft foundation.
The utility model content
The purpose of this utility model just is to overcome the lower deficiency of the anti-horizontal slip ability of traditional arch bridge abutment pier, in traditional abutment pier reinforced concrete floor bottom many rigidity inclination antislide piles are set, to improve the supporting capacity of the anti-horizontal slip of abutment pier, effectively bear the horizontal force that superstructure transmits.
The utility model is achieved in that n root (n 〉=8) the rigidity raked pile that quincuncial arrangement is set under traditional arch bridge abutment pier reinforced concrete floor, the length L of stake and the ratio of the diameter D of stake
Be 1.5～2.5, the tiltangle of stake is greater than 0 °, and each pile center is 2.5～3.5 apart from the ratio in a and stake footpath.Stressed longitudinal reinforcement only is arranged in 150 ° of scopes of tension one side in the stake, only arranges distributing bar in all the other scopes; The passive earth pressure q that rigidity inclination pile group side produces and the horizontal component T of rigidity raked pile side frictional resistance can significantly improve the horizontal antiskid bearing capacity of arch bridge abutment pier.
The utility model is by being provided with the anti-horizontal slip bearing capacity that rigidity taper pile group greatly improves traditional arch bridge abutment pier.

Fig. 3 is the utility model rigidity taper pile arrangement of reinforcement schematic diagram.
Be labeled as among the figure: 1-arch bridge abutment pier steel bar concrete foundation slab; 2-rigidity raked pile; 3-arch bridge top arch ring; 4-arch bridge abutment pier abutment pier cap; 5-arch bridge abutment knee wall; The stressed longitudinal reinforcement of 6-; The 7-distributing bar; The 8-stirrup.
The specific embodiment
Embodiment:
As shown in Figure 1, 2, the rigidity raked pile (2) that 11 steel concrete of quincuncial arrangement are made is set, the length L of rigidity raked pile (2) and the ratio of diameter D under arch bridge abutment pier reinforced concrete floor (1)
Be 2, the tiltangle of rigidity raked pile (2) is 10 °, and each rigidity raked pile (2) center to center distance a is 2 with the ratio in stake footpath.Rigidity raked pile (2) arrangement of reinforcement as shown in Figure 3, stressed longitudinal reinforcement (6) only is arranged in 150 ° of scopes of tension one side in the rigidity raked pile (2), only arranges distributing bar (7) in all the other scopes.
Claims (1)
1. limit, an antiskid moving arch bridge basis is honest, it is characterized in that being provided with the n root rigidity raked pile (2) of quincuncial arrangement under arch bridge bridge pier reinforced concrete floor (1), n 〉=8; The ratio of the diameter D of the length L of rigidity raked pile (2) and rigidity raked pile (2)
Be 1.5～2.5, the tiltangle of rigidity raked pile (2) is greater than 0 °, and each rigidity raked pile (2) center to center distance a is 2.5～3.5 with the ratio in stake footpath; Stressed longitudinal reinforcement (6) only is arranged in 150 ° of scopes of tension one side in the stake, only arranges distributing bar (7) in all the other scopes.
