Description
Technical field
The invention belongs to bridge engineering antidetonation and cushion technique field, relate to a kind of landscape configuration presstressed reinforcing steel bridge pier, between bridge pier and basis, rubber layer is set simultaneously, thereby realize the Self-resetting and power consumption function of bridge pier under geological process.This invention is with low cost, and anti-seismic performance is outstanding, easy construction, and effectively restrainer, has good development prospect.
Background technology
In recent years, along with the raising people of people's living standard are also more and more higher for the requirement of antidetonation shock attenuation, especially since Wenchuan earthquake in 2008, the various disasters that earthquake causes more and more cause people's attention, not only to building a building but also also requiring more and more higher for building facilitiess such as bridges.In Wenchuan earthquake in 2008, hundreds of bridge blocks destroy in earthquake, its mode of failure mainly contain bridge pier fracture beam destroy or directly fall beam destroy.The serious impact that this causes Post disaster relief, has brought massive losses more to the country and people's safe property.Therefore the antidetonation shock attenuation performance of researching and developing bridge has great importance.
At present the antidetonation of bridge pier is mainly to increase foundation depth and strengthens being connected of basis and ground, makes basis firmer, the damage of bridge pier when reducing coming earthquake.But the effect of this mode during for large-scale earthquake is little, there is no at present a kind of Antiseismic and shock-absorbing installation of destroying under bridge pier geological process of effectively preventing, in a word at present for the shockproof effect of bridge pier not obvious.The present invention proposes a kind of pier column and separates with basic, and configures the connected mode of transverse prestress muscle, ensures to meet load requirement under normal operating condition, and certain recovery and power consumption function is provided when coming earthquake, realizes and reduces the antidetonation shock attenuation requirement that bridge pier destroys; In addition, if the replaceable landscape configuration presstressed reinforcing steel of the one Self-resetting that this invention proposes power consumption bridge pier is destroying under large shake effect, the replacing that can carry out bridge pier to it, makes aspect the bridge reparation after shake easier.This invention can overcome the deficiency of above-mentioned bridge pier seismic measures, for bridge earthquake resistance provides more multifarious technical support, has great practical meaning in engineering.
Summary of the invention
The present invention provides a kind of replaceable landscape configuration presstressed reinforcing steel Self-resetting power consumption bridge pier, and goal of the invention is to utilize under geological process the restoring force of transverse prestress muscle to realize the Self-resetting function of bridge pier; Meanwhile, filled rubber layer between bridge pier and basis, realizes the clamping function of bridge pier and realizes bridge pier power consumption under geological process; The present invention provides a kind of replaceable landscape configuration presstressed reinforcing steel Self-resetting power consumption bridge pier in addition, can realize the quick-replaceable reparation after seismic damage.
To achieve these goals, the present invention has taked following technical scheme.
The replaceable landscape configuration presstressed reinforcing steel of one of the present invention Self-resetting power consumption bridge pier, it comprises prestressed reinforced concrete post 1, longitudinal prestressing muscle 2, common stirrup 3, rubber layer 4, strengthens stirrup 5, transverse prestress muscle 6, ground tackle 7, basis 8.The interior configuration longitudinal prestressing of prestressed reinforced concrete post 1 muscle 2 and common stirrup 3, the position of passing at transverse prestress muscle 6 arranges strengthens stirrup 5; Prestressed reinforced concrete post 1 is placed in to be with in reeded basic 8, and prestressed reinforced concrete post 18 is connected by the transverse prestress muscle 6 that passes across prestressed reinforced concrete post 1 with basis, between filled rubber layer 4.
Prestressed reinforced concrete post 1 and basis 8 adopt high-strength concrete.
Transverse prestress muscle 6 is non-bending steel cable, and the position reserving hole channel that the transverse prestress muscle 6 of prestressed reinforced concrete post 1 passes adopts post stretching stretch-draw non-bending steel cable.
Prestressed reinforced concrete post 1 is prefabricated, and construction adopts fabricated construction.
Function of the present invention is as follows:
Its restoring force of utilizing transverse prestress muscle realizes the Self-resetting function of bridge pier; Groove on basis is as the positioner of bridge pier, and between bridge pier and basis, filled rubber layer carries out damping power consumption; Bridge pier separates with basic, and transverse prestress muscle adopts post-tensioned construction to be convenient to the replaceable of bridge pier, thereby finally realizes Self-resetting, power consumption, the replaceable function of bridge pier.
Transverse prestress muscle is non-bending steel cable, utilizes its restoring force to realize the reset after move prestressed reinforced concrete post position in earthquake.Transverse prestress muscle adopts post-tensioned construction, and reserving hole channel in prestressed reinforced concrete post, is convenient to the replacing of prestressed reinforced concrete post.
Filled rubber layer between prestressed reinforced concrete post and basis, in earthquake, the extruding of rubber layer etc. realizes the power consumption to prestressed reinforced concrete post, reduces the destruction of prestressed reinforced concrete post in earthquake.
Prestressed reinforced concrete post is positioned in the basis that draw-in groove is set in advance, filled rubber layer between the two, if large earthquake centre prestressed reinforced concrete post occurs to destroy, girder does not come off, can set up the quick-replaceable that support girder ensures prestressed reinforced concrete post, realize the quick reparation of bridge.
Compared with prior art, advantage of the present invention is as follows:
1) the transverse prestress muscle in the present invention, can realize the Self-resetting function in earthquake of bridge pier, has increased the flexibility of bridge pier, has improved the ductility that earthquake Bridge destroys.
2) in the present invention, the rubber layer between prestressing force bridge pier and basis is realized the power consumption to bridge pier in earthquake,, the favourable damping power consumption that realizes girder construction.
3) the present invention proposes a kind of novel bridge pier and the basic structure separating, and realizes the replaceable of bridge pier, thereby can realize the quick reparation after bridge collapse.
4) the present invention needs cost lower, just can realize the high ductility of bridge pier and the failure mode of power consumption, and realizes the replaceable of bridge pier in the time repairing, and effectively reduces financial cost, has larger practical meaning in engineering.
