Problems solved by technology

[0003] The present invention is to avoid the shortcomings of the above-mentioned prior art, and to provide a transitional subgrade for treating vehicle jumping at the bridge head, so that the road surface near the bridge head will continue to settle without causing a sudden change in settlement, and fundamentally solve the problem caused by sudden changes in road surface settlement. bridge jump problem

Embodiment Construction

[0017] In this example, figure 1 As shown, the bridge includes pile foundation 9, bridge pier 10 and abutment 1; the transition road section includes road surface, reinforced concrete hollow slab 3 and backfill soil 2;

[0018] see figure 1 , the present embodiment is that one end of the reinforced concrete hollow slab 3 having the same width as the subgrade width is implanted in the abutment 1 with a fixed steel bar 4, and the reinforced concrete hollow slab 3 at the position of the fixed steel bar 4 is buried under the pavement cushion 5; The other end of the reinforced concrete hollow slab 3 is placed on the end support 11 near the original embankment 6, so that the reinforced concrete hollow slab 3 is placed obliquely between the abutment 1 and the end support 11 to form a transition roadbed. The rigidity of the reinforced concrete hollow slab 3 is set to be consistent with or close to the rigidity of the abutment 1 .

[0019] In specific implementation, such as figure...

Abstract

The invention discloses a transition roadway for managing bumping at bridge-head, which is characterized in that one end of each reinforced concrete hollow slab of which the width is same as that of the roadway is embedded into an abutment with fixed reinforcing steel bars, and the reinforced concrete hollow slabs at the positions at which the fixed reinforcing steel bars locate are buried below a bed course; the other ends of the reinforced concrete hollow slabs are arranged on end strutting pieces closing to the original embankment, so that the reinforced concrete hollow slabs are obliquely arranged between the abutment and the end strutting pieces to form a transition roadway; and stiffness of the reinforced concrete hollow slabs is consistent with that of the abutment. The transition roadway provided by the invention is used, so that settlement and abrupt change of the road surface nearby the bridge head are not caused by continuous settlement, thus fundamentally solving the problem of bumping at bridge-head resulting from the settlement and abrupt change of the road surface.

Description

technical field [0001] The invention relates to a transition roadbed structure used for controlling the phenomenon of vehicle jumping at the bridge head. Background technique [0002] Bridge head jumping is a phenomenon in which vehicles run bumpy due to large differences in settlement due to the large difference in stiffness between the abutment and the roadbed. The vehicle jumping at the bridge head seriously affects the safety and comfort of driving, and the impact load generated by the vehicle jumping has a very adverse effect on the abutment. Slowing down bridge head jumping and improving driving safety and comfort has always been a difficult problem in the engineering field, and it is also one of the problems that need to be solved urgently in highway engineering construction. Many scholars at home and abroad have done a lot of research on the mechanism and solutions of the phenomenon of vehicle jumping at the bridge head, and put forward some control measures. Exist...
