Abstract
The utility model discloses a U-shaped bridge abutment provided with a reinforced concrete cover plate which includes an abutment body and a flarewall. The utility model is characterized in that the upper ends of the abutment body and the flarewall are provided with an integral reinforced concrete cover plate; the reinforced concrete cover plate is cast on the abutment body and the flarewall. The U-shaped bridge abutment provided with a reinforced concrete cover plate has the advantages that: 1, the structure stress states of the abutment body and the flarewall of the U-shaped bridge abutment are improved; 2, the infiltration of surface water to an abutment cavity is reduced by the reinforced concrete cover plate, thereby reducing the effects of the filling earth of the abutment cavity to the active earth pressure and the frost heaving of the abutment body and the flarewall; 3, the direction pressure of a running load to the filling earth of the abutment cavity is obstructed by the reinforced concrete cover plate, thereby reducing the active earth pressure of the abutment body and the flarewall caused by the filling earth of the abutment cavity.
Description
Technical field
The utility model relates to a kind of U type abutment with the steel concrete cover plate.
Background technology
Entity gravity U type abutment is made up of with the aileron that is connected the embankment both sides the abutment body of supporting spanning, wall body majority is the barnacle bricklaying, be applicable to that the depth of fill is 4 to 10 meters single hole and a multiple span bridge, its technical characterstic shows as: 1, the wall health is long-pending big, simple in structure, basis end pressure-bearing surface is big and stress is less; 2, the platform cavity segment is many fills with dank material; 3, the platform chamber easy ponding that bankets causes soil pressure to increase, be subject to frost heave, and makes the side wall cracking; 4, force-bearing situation more complicated, it bears load actings in conjunction such as power that soil pressure, spanning transmit, driving; 5, the more and origin cause of formation of all kinds of diseases is complicated, and it is more also more loaded down with trivial details to keep in repair related factor, as: because the not enough caused drainage of the fill compaction degree at position, platform chamber damages, cause platform chamber ponding and cause the disease that soil pressure increases and frost heave is produced.
Summary of the invention
The purpose of this utility model just provides a kind of U type abutment of band steel concrete cover plate of the structural stress state that can improve abutment abutment body and aileron.
The U type abutment of band steel concrete cover plate of the present utility model comprises abutment body, aileron, is characterized in that the upper end of abutment body, aileron is provided with the monolithic reinforced-concrete cover plate, and the steel concrete cover plate now is cast on abutment body, the aileron.
The advantage of the U type abutment of band steel concrete cover plate of the present utility model is: the structural stress state that 1, has improved U type abutment abutment body and aileron; 2, reduced the infiltration of surface water by adding the steel concrete cover plate, banketed to the active earth pressure of abutment body and aileron and the influence of frost heave generation thereby reduced the platform chamber to the platform chamber; 3, intercept the direct pressure that traffic load bankets to the platform chamber with the steel concrete cover plate, banket to the active earth pressure of abutment body and aileron thereby reduced the platform chamber.
