Continuous increase, automobile overload phenomenon happens occasionally, the event for causing girder seriously to roll or even topple under extreme uneven loading action
It happens occasionally, socially produces totally unfavorable influence.
In practical applications, traditional Single column pier bridge direction across bridge is using single fulcrum support, in overloaded vehicle uneven loading action
Under, structure transverse direction resistance to capsizing is poor.
In order to guarantee the structure safety of existing Single column pier bridge, the remedial measure that this field is usually taken is to Single column pier bridge
Beam carries out antidumping reinforcing, and existing reinforcement means mainly has following four:
One, Single column pier is changed to wall type solid pier, support is increased in former support position two sides by beam body jacking；
Two, add pier stud in only column two sides, after being jacked by beam body on new pier stud erection support；
Three, corbel type structure is set at the top of former Single column pier and forms support by section, is formed in bracket and is pacified by section two sides
Fill support；
Four, the defect too weak due to General Purpose Rubber support anti-pulling ability, original support is improved to can satisfy only column
The anti-pulling support that pier composite beam bridge antidumping requires.
Wherein, although by increase pier stud method can maximally efficient raising girder resistance to capsizing, to under-clearance
It is unfavorable with bridge beauty.
And the method by adding corbel type structure or anti-pulling support is then more demanding to technical level, and the above reinforcing
Method is both needed to jack girder, and reinforcement cost is relatively high.
It therefore, it is necessary to be improved to existing anti-overturning devices, overcomes the deficiencies of existing technologies, improves construction efficiency.
