Abstract

The invention discloses a transition device for eliminating vehicle jumping at the bridge head, which comprises a soil retaining platform, an overlying lap, an abutment, an embankment end and a plurality of viscoelastic height-adjustable supports; each viscoelastic height-adjustable support is located on the soil retaining platform Above, one side of the overlying board is lapped on the abutment, and the other side of the overlying board is located on each viscoelastic height-adjustable support and its end is in contact with the end of the embankment. This device can effectively solve the problem of Bridge head jumping problem caused by uneven settlement of rigid abutment and subgrade.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering and relates to a transition device for eliminating vehicle jumping at the bridge head. Background technique [0002] The road-bridge transition section is a cancer that restricts the overall rapid development of road traffic, and vehicle jumping at the bridge head has become a worldwide problem. The main factors causing the vehicle jump at the bridge head are: uneven settlement, sudden change in stiffness, vehicle speed and the anti-vibration performance of the vehicle itself. As far as urban road conditions are concerned, it is mainly caused by uneven settlement at the junction between flexible roads and rigid structures due to different stiffnesses, resulting in staggered platforms. There are differences in the composition materials, stiffness, strength, and expansion and contraction of bridges and subgrade pavement, and concentrated stress is easy to form when the bridgehead connect...
