Embodiment 1

[0036] as attached figure 1 , 2 As shown, the present invention provides a device for solving bridge head jumping, which includes a single basic device for connecting the abutment and the roadbed. A device for solving bridge head jumping, which is composed of a foundation 2, a cover plate 1, and a connecting device; the cover plate 1 includes a cover beam and a plate; the connecting device includes a spring column 4 and a gasket 3, which can adjust and change the position of the cover plate Height and angle, there is space inside the unit for personnel to operate.

[0037] A row of spring posts 4 are respectively arranged on the bridge abutment and the subgrade road surface end of the device for solving bridge head jumping, and a plurality of gaskets 3 are nested on the spring posts 4 to bear the force transmitted from the cover plate 1 . The spring column 4 is mainly used to keep the gasket 3 within a certain position range, so as not to allow the gasket 3 to move arbitrari...

Embodiment 2

[0051] as attached Figure 4 , 5 , the present invention provides a device for solving bridge head jumping, the device includes three basic devices for connecting the bridge abutment and the roadbed. Each basic device is composed of a foundation 2, a cover 1, and a connecting device. Expansion joints 5 are used to connect between the cover 1 of a single basic device, and between the cover 1 of a single basic device and the abutment or road surface. The deck 1 comprises deck beams and plates. The connection device includes a spring column 4 and a gasket 3, which can adjust and change the height and angle of the cover plate, and there is space inside the device for personnel to operate.

[0052] Each basic device is provided with a row of spring columns 4 on the side of the abutment and the side of the subgrade road surface. The gasket 3 nested on the spring column 4 is used to bear the force transmitted from the cover plate 1, and the main function of the spring column 4 is t...

Abstract

The invention discloses a device for solving vehicle jumping at the bridge head, which includes one or more independent basic devices. The device for solving the problem of vehicle jumping at the bridge head is connected to the bridge abutment and the roadbed. The single basic device consists of a foundation, a cover plate , Connection device composition. The connecting device includes spring posts and spacers, which can be adjusted to change the height and slope of the cover; there is space inside the basic device for personnel to operate. The invention also discloses a method for solving the vehicle jumping at the bridge head. The invention can control the height and slope of the cover plate only by adjusting the spacer, so as to realize the connection between the bridge abutment and the road surface. Compared with other inventions for solving bridge head jumping, the present invention is simple, strong in operability and convenient in maintenance.

Description

technical field [0001] The invention relates to a device for solving vehicle jumping at the bridge head, in particular to a device and method for solving the problem of vehicle jumping at the bridge head, and belongs to the technical field of municipal administration. Background technique [0002] At present, in the field of roads and bridges, the phenomenon of vehicle jumping at the bridge head is relatively common. The main causes of vehicle jumping 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, resulting in staggered platforms. There are differences in the composition materials, stiffness, strength, and expansion and contraction of bridges, subgrades, and pavements, and concentrated stress is easily formed when the bridgehead conne...
