Adaptive transition section device for solving bridge head bump

Abstract

The invention discloses an adaptive transition section device for solving bridge head bump. The adaptive transition section device comprises a transition pit, a base plate, a transition panel, and lifting adjusting devices, wherein the transition pit is arranged between a roadbed and the bridge head in a sunken mode; the base plate is arranged at the bottom of the transition pit; the two ends of the transition panel are connected with the roadbed and the bridge head in an overlapped mode correspondingly, and the upper surfaces of the overlapped positions are flush; and the lifting adjusting devices can expand and contract axially, one ends of the lifting adjusting devices are fixed to the base plate, and the other ends of the lifting adjusting devices vertically extend upwards and are fixed to the transition panel; and the lifting adjusting devices are arranged at least corresponding to the four corners of the transition panel. According to the adaptive transition section device for solving bridge head bump, it can be ensured that the bridge head is in smooth connection with the roadbed, and the problem of bridge head bump is solved.

Description

technical field [0001] The invention relates to the technical field of solving the problem of vehicle jumping at the bridge head, in particular to an adaptive transition section device for solving the vehicle jumping at the bridge head. Background technique [0002] Affected by factors such as treatment measures and structural stiffness, there is usually a big difference between the settlement of the bridge head pile foundation and the settlement of the bridge head subgrade section. Especially in the soft soil area, the difference is obvious. The bridge pile foundation in the soft soil area is driven into a good bearing layer, while the measures taken for the surrounding roadbed are relatively weak, and generally only a part of the treatment is handled according to the situation. And due to the limitations of the preliminary survey methods and understanding, after the project is completed and put into operation, the preliminary design may not achieve the expected effect, res...
