Road and bridge connection structure capable of effectively relieving bridge bump

2016 
The invention discloses a road and bridge connection structure capable of effectively relieving bridge bump. The connection structure comprises an inverted frustum-shaped structure and filler. A flexible structure layer good in integrity and large in stiffness is formed by using the inverted frustum-shaped structure and mixing soil processed by sodium silicate, namely sodium silicate stabilized soil. By using the modulus gradual change principle and taking settlement factors including a foundation and a roadbed into consideration, an inverted frustum-shaped structure reinforcing area is arranged on a road and bridge transition section, the sodium silicate stabilized soil is added into the structure reinforcing area, one end of the flexible structure layer is fixed to an abutment, the other end of the flexible structure layer is connected with the roadbed, too large differential settlement is eliminated, and stable transition between the modulus of the rigid abutment and the modulus of the flexible roadbed is achieved. The connection structure can effectively reduce bridge bump and secondary bump problems, improves comfort and safety of driving, greatly reduces maintenance cost for bridge processing, and is remarkable in economic benefit.
