Gasket adjusting devices for treating bumping at bridge head

Abstract

The invention provides gasket adjusting devices for treating bumping at a bridge head. At least two gasket adjusting devices are arranged in the horizontal direction of one end of an individual bridge, and each gasket adjusting device comprises a base, wherein a plurality of gaskets are arranged on the base, first bolt holes for fixing the gasket adjusting device on a bridge pier are formed in the front, back, left and right of the base respectively, a groove is formed in the upper end of the base, multiple rows of rollers are arranged in the groove, limiting edges for ensuring that at least the gaskets above the rollers are located in the groove are arranged on the periphery of the groove, a top plate is arranged above the topmost gasket in the base and connected with the topmost gasket, and the top plate is fixed at the lower end of the bridge through second bolt holes. The gasket adjusting devices are novel in design, simple in structure, convenient to use, safe, reliable, low in cost, high in practicability, environment-friendly, saving, easy to popularize and reusable, and can effectively eliminate or avoid bumping at the bridge head.

Description

technical field [0001] The invention belongs to the field of highway engineering, and in particular relates to a gasket adjusting device for treating vehicle jumping at the bridge head. Background technique [0002] The bridge settlement at the bridge head of the highway is generally small, while the settlement of the embankment at the back of the abutment connected to the bridge head is relatively large. Due to the large settlement difference between the bridge and the abutment back, the vehicle jumps when passing the bridge head, forming a bridge head jump. Bridge head jumping will not only cause discomfort to drivers and passengers, accelerate wear and tear of vehicles and bridges, increase operation and maintenance costs, reduce road traffic efficiency, and even cause traffic accidents resulting in loss of life and property. It has become a common problem in highway engineering. At present, the treatment of vehicle jumping at the bridge head is generally to strengthen th...

Problems solved by technology

Bridge head jumping will not only cause discomfort to drivers and passengers, accelerate vehicle and bridge wear and tear, increase operation and maintenance costs, reduce road traffic efficiency, and even cause traffic accidents resulting in loss of life and property. It has become a common problem in highway engineering

At present, the treatment of vehicle jumping at the bridge head is generally to strengthen the treatment of the weak foundation at the back of the abutment, improve the compaction quality of the subgrade at the back of the abutment, adopt light subgrades, pour bridge slabs at the bridge head, and build transitional roads. Although there are certain effects, they are not completely Solve the problem of vehicle jumping at the bridge head, and these treatment measures are time-consuming, laborious and costly. Every time the problem of vehicle jumping at the bridge head occurs, the subgrade and pavement at the back of the platform can only be treated passively, which has become a major problem in highway engineering worldwide
